AMD tasted a bit of success with its Phenom II series of processors, which reflected in recent market share figures, where the company's share grew by around 5 percent, despite a fall in sales throughout the PC processor industry. Leading its pack currently, is the Phenom II X4 955 Black Edition, which holds a full-featured 45 nm Deneb core with unlocked bus multiplier, and AM3 platform support. It seems like AMD isn't stopping at this. The company is preparing a new model targeted at the enthusiast segment, called Phenom II TWKR ("tweaker").

High-end PC manufacturer Maingear PC has reportedly received this chip in a display model form, and looks forward to incorporating it in its lineup of PCs. Very little is known at this point in time, about this chip, beyond the point that it will provide better clock-speeds compared to the Phenom II X4 955. We can tell that it retains the AM3 socket package from the looks of it, and comes in a pretty jewel-case. AMD is yet to announce the chip, or disclose more about how it plans to sell it, and at what price.

AMD announced a platform refresh today for Dragon platform technology, including the new AMD Phenom II X4 955 Black Edition processor. As AMD's fastest ever quad-core processor, it brings all the capabilities gamers, enthusiasts and do-it-yourselfers have come to expect from AMD, including world record setting performance, high-speed DDR3 memory support and AMD OverDrive 3.0 technology, giving users more control over their computing experience.

The Dragon technology refresh consists of the new AMD Phenom II X4 955 Black Edition processor, AMD 7-Series chipsets and award winning ATI Radeon HD 4890 graphics. With this platform refresh, AMD is combining its fastest processor with the massive graphics processing muscle of its most powerful GPU to deliver high definition video entertainment and "beyond HD" resolutions3 that allow gamers to take the latest games to the extreme.

AMD has implemented price-cuts for its desktop CPUs under the Athlon X2, Phenom and Phenom II series. The price cuts affect Athlon X2 model 7750, Phenom X3 models 8750, 8650 and 8450, and the company's current flagship product Phenom II X4 940. The Phenom X3 8750 in particular, is pushed into the $100 mark with its 26% reduction in price.

With the revised price-table, AMD looks to make space for three upcoming products that include the much awaited Phenom II X4 955 Black Edition. Expected to have reached retail in the US on April 20, the chip has been pushed to a later date, when the company plans four launches in all: Phenom II X4 955, Phenom II X4 945, Athlon X2 7850, and AMD Overdrive 3 software.

Phenom II X4 945 is a 3.0 GHz quad-core processor with its multiplier locked at 16x, while the Athlon X2 7850 takes over as the company's flagship dual-core chip spec'd at 2.80 GHz, 3 MB of total cache, and a TDP of 95W. The chip is based on the 65 nm Kuma core. Phenom II X4 955 has already received listings in Europe, where it is priced at €229.90 including taxes.

AMD is attempting to set its record straight with the Phenom II series of 45 nm desktop processors. The company had started off its Dragon desktop platform with the introduction of its flagship CPU, the Phenom II X4 940. This processor however, is not compliant with the AM3 socket, and will not support DDR3 memory, unless an AM3 socket motherboard can provide DDR2 memory support. Come April 20, and AMD will have released its newest processor: Phenom II X4 955 Black Edition. Based on the 45 nm Deneb core, this processor supports AM3 socket motherboards, and DDR3 memory. It features a core clock speed of 3.20 GHz (16.0 x 200 MHz), 512 KB of L2 cache per core, and 6 MB of L3 cache. It is overclocker-friendly thanks to its unlocked bus multiplier, and the "massive headroom" AMD has been brandishing lately.

One of our sources from Hong Kong was able to make an early-purchase this processor in its retail "processor in a box" (PIB) package (marked with the OPN HDZ955FBGIBOX), from the Golden Computer Parts Center, who took a few snaps of the package. It could be bought for around HKD 2170 (US $280).

New information from German tech site Hardware-Infos, has lead to the news that AMD's fastest CPU, the Phenom II X4 955, could be available from April 20th this year. Using the AM3 socket, the CPU is made using AMD's latest 45 nm fabrication process, and is clocked in at 3.2 GHz (16*200 MHz). Sporting 512 KB of L2 cache per core, and a 6 MB L3 cache, AMD have managed to match the 125 W TDP of the recently released Phenom II X4 940.

While AMD played smart in diverting all its engineering resources in designing only one core: the Deneb / Shanghai, and then carving out umpteen SKUs out of them based on disabling cores, and/or setting L3 cache amounts, its implementation seems to be shoddy, to the least. Weeks ago, a Korean enthusiast found an easy way to unlock the factory-disabled fourth core on some Phenom II X3 (Heka) processors. A fresh report suggests that it is possible to enable the complete L3 cache on the Phenom II X4 800 series processors.

The series is AMD's line of Deneb-based 45 nm quad-core processors with 2 MB of L3 cache disabled, leaving 4 MB that can be addressed by the processor. An enthusiast found the Phenom II X4 810 processor to be spontaneously able to address 6 MB of L3 cache, when used on an ASRock AOD790GX /128M motherboard. The most likely cause of this could be "poorly-coded" motherboard BIOS that is able to see the Deneb core "as is". The motherboard was using BIOS version 1.40, that adds Phenom II support. The additional cache was found to have a positive impact on system performance. Beyond that, the enthusiast did not provide an explanation. After clearing the CMOS of the motherboard, it was able to correctly detect the processor with its intended specifications.

It is a well-known fact that AMD has been carving out triple-core and dual-core Phenom/Phenom II series processors out of complete Agena/Deneb dice with one or two cores disabled. In a fresh revelation, a Korean enthusiast claims to have discovered that it is rather easy to unlock the disabled core on Phenom II X3 processors, provided the motherboard supports the Advanced Clock Calibration (ACC) feature that is meant to enhance overclocking using AMD's Overdrive software. The enthusiast claims the soft-mod to have worked in his/her case, where a Phenom II X3 710 was paired with a Biostar TA790GX 128M motherboard. The CPU was overclocked to 3.12 GHz, with a vCore setting of 1.37 V.

The method employed: Set the appropriate BIOS setting for the Advanced Clock Calibration feature to "Auto", save settings and restart. The system will be able to deal with the disabled core, and off load some work to it. The processor with the "additional" core was tested to be Prime95 stable and was able to boost 3DMark06 CPU score by as much as 1,000 points. Let the screenshots below speak for themselves:
The method:

In yet another overclocking feat using AMD's Phenom II series processors, Team Finland set a new 3DMark06 world-record score of 35,698 3DMarks. The team consisted of renowned overclockers Petri "SF3D" Korhonen Sampsa Kurri and Sami "macci" Mäkinen. The team used AMD's DDR3-supportive AM3 platform and used high-performance DDR3 memory to demonstrate its overclocking capabilities. The bench consisted of:

• AMD Phenom II X4 6187MHz (4500MHz NB) under Dragon F1EE pot, liquid nitrogen cooling
• ASUS M4A79T Deluxe (790FX chipset)
• Corsair XMS3-2133 2x1GB DDR3-1800 CL7-7-7-1T
• 2x Radeon HD 4870 X2 830/950MHz with stock cooling
• Thermaltake Toughpower 1200W

As NordicHardware notes, for the first time in ages, an AMD-platform topped 3DMark06 Hall of Fame, crossing the previous record holder by 150 3DMarks. Validations of the score can be found here. A video of the feat has been posted on YouTube, and can be viewed here.

Shuttle Inc., the market leader in the Mini-PC segment and manufacturer of Multi-Form-Factor solutions expands the CPU compatibility for the XPC Barebone SN78SH7. A newly published BIOS version now enables the use of AMD Phenom II processors. Besides current AM2 and AM2+ processors, the state-of-the-art 45nm models Phenom II X4 940 and Phenom II 920 with four cores are now also officially supported.

The compact XPC Barebone SN78SH7 with case dimensions of only 32.5 x 20.8 x 18.9 cm (DWH) uses brushed aluminium with a high-grade finish. The core of the robust Mini hides a NVIDIA GeForce 8200 chipset and the graphics processor of the same name. Picture and sound are transferred in excellent HD quality via the integrated HDCP-compliant HDMI interface. The package is rounded off by a PCI-Express 2.0 (x16) and one PCI slot, a Gigabit LAN interface and eSATA connectors. The Shuttle XPC Barebone SN78SH7 is now available at an RRP of EUR 281 (ex VAT). The Phenom II-supportive BIOS can be obtained from here.

BIOSTAR MICROTECH INT'L CORP., a professional manufacturer of motherboards today announced the TA790GX A3+, the first AMD "Dragon Platform" qualified motherboard with next generation AMD AM3 Phenom II processors support.

The Phenom AM3 processors are able to support up to DDR3 1600MHz memory speed (when equipped with AMD 790FX northbridge), the TA790GX A3+ offers Dual x16 PCI-E 2.0 graphics interfaces to deliver up the latest ATI CrossFireX support for the ultimate gaming platform.

AMD today extended its Phenom II line-up with five new processors, including the industry's only 45nm triple-core CPUs and three new AMD Phenom II quad-core processors. Part of the fire breathing AMD Dragon platform, these new Phenom II chips fit in either AM2+ or AM3 sockets and support DDR2 or next generation DDR3 memory. The new triple-core and quad-core AMD Phenom II processors are available immediately with the following model numbers:

• AMD Phenom II X4 910 2.6GHz, 6MB of L3 cache
• AMD Phenom II X4 810 2.6GHz, 4MB of L3 cache - $175
• AMD Phenom II X4 805 2.5GHz, 4MB of L3 cache
• AMD Phenom II X3 720 Black Edition 2.8GHz, 6MB of L3 cache - $145
• AMD Phenom II X3 710 2.6GHz, 6MB of L3 cache - $125

All five Phenom II chips have the same 95W TDP.

Intel is planning on a newer flagship desktop CPU to lead the Core i7 Extreme Edition pack: the Core i7 975 Extreme Edition (XE). The model surfaced at an XtremeSystems forum thread where overclockers FUGGER and Mikeguava took a shot at the 3DMark05 world record of 45,474 3DMarks, set by AMD at its presentation of the Phenom II X4 processor running at speeds of around 6.30 GHz. The overclockers used a bench consisting of the new Core i7 975 XE, Gigabyte GA-EX58 Extreme motherboard, two Radeon HD 4870 X2 accelerators in a CrossFireX setup, powered by a PC Power & Cooling Silencer 750W PSU. The CPU was cooled by a custom-made copper cooling pot. At a clock speed of 5,239 MHz and the graphics cards running at reference speeds, the bench cracked the world record to reach 47,026.

During the course of this feat however, we get to know more about the Core i7 975 XE. The new premium offering by Intel comes with a clock speed of 3.33 GHz. It achieves this frequency using a bus multiplier of 25X. Intel built this chip on the new D0 revision of the Bloomfield core, on which the company also plans to release fresh batches of the Core i7 920. Apart from the unlocked bus multiplier and the broader QuickPath Interconnect bandwidth of 6.4 GT/s, other features remain standard: 4 processing cores supporting 8 threads with HyperThreading enabled, 256 KB of L2 cache per core, 8 MB of shared L3 cache, and a triple-channel DDR3 memory interface.

Beating its chest on the "massive headroom" (read: clock speed increment potential) its newest line of processors, the Phenom II have, it was about time the company utilized the said headroom to carve out new SKUs. With the AM2+ exclusive Phenom II X4 940 already showing impressive overclocking potential, while shipping with a clock speed of 3.00 GHz, the company is planning to increase stock clock speeds in increments of 100 MHz (0.5x multiplier) with a string of SKUs post Phenom II X4 950. This according to the insider sources a German website called AMD News caught up with.

All the upcoming processors will be built on the AM3 package, making them compatible with DDR3 and DDR2 memory standards. With the Phenom II X4 950 being clocked at 3.10 GHz, succeeding SKUs take 100 MHz steps, starting from a Phenom II X4 960 at 3.20 GHz to a Phenom II X4 990 at 3.50 GHz. Despite the high clock speeds, the chips will continue to maintain rated TDPs of 125W. At some point within the succession, AMD will crank up the HyperTransport interconnect speed from 1,800 MHz to 2,000 MHz. The launch-schedule for these processors will be spread throughout 2009.

With the AMD K8 architecture, AMD had made it very simple for CPUs and motherboards to get along. Memory support being purely subjective to the memory controller on the CPU, the only thing the motherboard chipset was left to do was to connect the rest of the system to the CPU using the HyperTransport interface. With the introduction of the DDR2 supportive AM2 socket that was mostly pin-compatible with socket 939, motherboard vendors took to cost-cutting using older s939 and s754-"supportive" chipsets such as the NVIDIA nForce 3. ASRock is one of them. The company used the nForce 3 in the AM2NF3-VSTA motherboard.

Having bought that motherboard in its time, might just pay off now, with the company including it in its latest socket AM3 CPU compatibility list. The motherboard might go on to support the latest Phenom II X4, X3 series; Athlon X4, X3 series, and other processors in AMD's 45nm desktop CPU lineup. That will also add to the reputation of the NVIDIA nForce 3 chipset being the only platform core-logic to span across three generations of CPU sockets: socket 754, socket 939, and socket AM2. And supporting AMD processors from three generations of sockets: AM2, AM2+ and AM3. This is what AMD originally conceived when designing its socket model. Unfortunately, vested commercial interests and "sandbagging" have plagued many a motherboard manufacturer who continue to discriminate CPU support within the AM2/3 socket series, to create new product lines, and to keep their sales up.

Better late than never, AMD is embracing the DDR3 memory standard. Its newest desktop CPU socket, the AM3, connects the processor to dual-channel DDR3 memory. Initial specifications about AMD's processors on the new socket suggest that DDR3 1333MHz (PC3-10600) will be held as the memory standard the integrated memory controllers on AMD's processors support. The far-east team of Tom's Hardware posted the first series of benchmarks of a Phenom II AM3 processor, when paired with DDR3-1333. The benchmarks featured Gigabyte's MA790FXT-UD5P motherboard along with Corsair's dual-channel DDR3-1333 kit running at DRAM timings of 9-9-9-24. The CPU-Z window also shows that the memory modules are running unganged, meaning that the two memory controllers of the Deneb core are independent, with each controller handling a 64-bit wide memory channel. This state is somewhat comparable to that of single-channel memory, except that multi-threaded applications will still be able to independently address memory on each channel, utilizing all the bandwidth on offer.

At the center of the test-bench was the AMD Phenom II X4 910, the company's first flagship quad-core AM3 processor. The X4 910 features a default clock speed of 2.60 GHz. The same chip was tested in two settings: default clock-speeds, and overclocked to 3.12 GHz (240 x 13.0 @ default vCore). The screenshots below show the test results for WPrime. The overclocked chip scored a crunch-time of 46.613 s (1M). The overclock did not affect SuperPi at all, with insignificant differences in the scores between the two. PC Mark 05 got a decent boost, while 3DMark06 didn't. Memory bandwidth and latency tests showed something strange, with the overclocked CPU (in effect memory) turning up with lesser latency (while normally, increase in clock speeds tend to step up latencies). The tests show that there are increments in performance with the use of DDR3 memory, though they are merely proportional to the clock speeds the memory is running at.

Barely a month into its launch, AMD's newest processors, the Phenom II X4 920 and Phenom II X4 940 Black Edition, are already in for global price-cuts, of as much as 20%, in the days to come. Sources close to the company indicate that the price-cuts are in view of the recent announcement by Intel to significantly lower the prices of certain models of its Core 2 Quad lineup, which pose direct competition to AMD's new chips.

Once implemented, the Phenom II X4 920 would sell for US $195, down from its launch-price of $235, and a whole $50 would be waived off the $275 price-tag of the Phenom II X4 940 Black Edition, sending it down to $225. These price-cuts are not yet officially confirmed or announced by AMD, and so it isn't known as to when exactly they get officially implemented. All prices in 1000 unit tray quantities.

In all past roadmaps, AMD told us that its DDR3-supportive CPU lineup would begin with the Phenom II X4 945. Evidently that is not the case. From a recent DigiTimes report, there was hint given that all's not well with AMD's DDR3 plans, with the company toiling hard to get DDR3 memory run smooth and stable on AM3 socket CPUs, with integrated DDR3 memory controllers. The same report also highlighted the larger issue of both AMD and Intel being reluctant in orchestrating an industry-wide transition to the newer DDR3 memory standard across all market-segments. Amidst all this, AMD seems to have a small change of plans with its entire Phenom II lineup, with several processors earlier thought to be based on AM2+, emerging now as DDR3-supportive AM3. Also, it is known that AMD's first DDR3-supportive flagship quad-core chip will be the Phenom II X4 925, which arrives before the 945 and the newer SKU that has come to light.

AMD finally seems to have put a realistic assessment of its processors, with its claims of the Phenom II X4 having "massive headroom" with its overclocking potential being validated once again, this time by Team Finland, at a CES overclocking event. Team Finland was able to overclock a Phenom II X4 940 processor at its highest stable clock speed of 6.30 GHz using extreme cooling. Earlier attempts to overclock the chip beyond the 6 GHz mark only yielded in test-beds that were able to POST, boot and display the clock speed using CPU-Z. This attempt however, was a benchmark-stable overclocking feat.

The bench consisted of a Phenom II X4 engineering sample, DFI LANParty Dark 790FXB-M2RS, OCZ DDR2-1066 memory, two Radeon HD 4870 X2 graphics cards in CrossfireX and Windows XP. The CPU cooling employed was liquid helium, which dropped the temperature to -242 degrees Celsius. To achieve a clock speed of 6.30 GHz, the processor's vCore was set at 1.84V, its bus speed at 280 MHz and a multiplier of 22.5 was set. The HyperTransport frequency multiplier was set at 8. The Radeon HD 4870 X2 accelerators were set at 800 MHz (core) and 950 MHz (memory). The machine was put through 3DMark05, where it ended with a world-record score of 45,474.

Unleashed earlier today AMD's Dragon platform has now been integrated into Dell's latest XPS 625 desktop PC. Starting at $999, the system is powered by a 3.0GHz AMD Phenom II X4 940 Black Edition processor, two ATI Radeon HD 4850 graphics cards in CrossFire mode, 8GB memory, and a 10,000 rpm hard drive. All that hardware is placed carefully in a special Dell aluminum chassis with a choice of either black or red accents, plus the AlienFX customizable lighting system inside it. For more information on the XPS 625 system, please click here.

With the official launch of the AMD Dragon platform, AMD lifed whatever NDA restrictions it had over the media to publish reviews of its Phenom II X4 processor, letting proper and final reviews make to the internet. Several tech-enthusiast websites have taken the opportunity. Reviewers put the Phenom II X4 940 Black Edition to test.

The Phenom II X4 940 Black Edition is AMD's flagship desktop CPU. With four processing cores clocked at 3.00 GHz, it embeds 2 MB L2 and 6 MB of L3 cache. Based on the AM2+ socket, it supports the DDR2-1066 standard. This processor is especially overclocker friendly with its unlocked FSB multiplier and the overall positive response from the reviewers on its overclocking headroom. Here are some of the reviews at:

Empowering consumers to get elite-level computing performance for under $900 U.S. dollars, AMD today launched "Dragon" platform technology for desktop PCs featuring the new AMD Phenom II X4 processor. Even the most demanding users such as enthusiasts and high-end gamers desire affordable systems capable of delivering HD entertainment, graphic-intensive game play at the highest settings their monitors can handle, as well as quick and easy transfer of video entertainment to and from mobile devices. Dragon platform technology provides the power to do it all by combining AMD's highest-performing CPU, the AMD Phenom II X4 processor, with award winning ATI Radeon HD 4800 Series graphics and AMD 7-Series chipsets. And it's offered at an incredible value with Dragon-based systems available for up to $1,200 U.S. dollars less than competing systems that deliver comparable performance.

Leading global PC manufacturers HP, Dell and Alienware plan to offer Dragon platform technology-based desktop systems in the first quarter of 2009, with Dell offering immediate availability in its Dell XPS desktop line. "The XPS 625 desktop powered by AMD's Dragon platform technology features new AMD Phenom II processors to enable a significant boost in speed for enhanced gaming, as well as the flexibility to enable multi-tasking and HD video capabilities free from delays, stalls and lags," said Arthur Lewis, general manager of Dell Gaming Group. "The XPS 625 gives gamers the unbelievable experience they expect at a price point that won't break the bank."

AMD is heading towards kicking off its desktop CPU lineup built on the 45nm manufacturing process this 8th of January. The company also started off with selling certain "business-class" CPUs last year, CPUs that are rated for long MTBF, giving it a little incentive for business/office PC manufacturers for using the processors in their models. The company is looking to do the same with its 45nm desktop CPU lineup, with six business-class CPUs on the cards, sources tell DigiTimes.

The models planned are dual-core Athlon X2 B23 (2.9GHz, 2MB cache) and B21 (2.7GHz, 2MB cache), triple-core Phenom II X3 B73 (2.8GHz, 7.5MB cache) and B71 (2.6GHz, 7.5MB cache), and quad-core Phenom II X4 B93 (2.8GHz 8MB cache) and B91 (2.6GHz 8MB cache). These processors are slated for Q3 2009. Following the introduction of these, the company plans to phase-out its current business class CPUs by issuing last-order notices for them in Q4. These will be issued for Phenom II X4 9850B, 9750B, 9600B and Phenom II X3 8850B, 8750B, 8600B as well as Athlon X2 5600B, 5400B, 5200B, 5000B, 4850B, 4450B and Athlon 1640B.

AMD will be launching its 45nm desktop CPU lineup with two of its flagship CPUs, the Phenom II X4 940 Black Edition and Phenom II X4 920, clocked at 3.00 GHz and 2.80 GHz respectively. Retailers can start selling these two processors in the processor in a box (PIB) form starting from January 8.

The suggested retail prices for the EMEA region according to NordicHardware are around 250€ for the Phenom II X4 940 Black Edition and 220€ for the Phenom II X4 920. The same source points at the US markets' suggested pricing, which states US $280 for the Phenom II X4 940 Black Edition, and $230 for the Phenom II X4 920. This puts AMD's flagship processor in the price range of Intel's Core i7 920 and Core 2 Quad Q9450 processors, while AMD's platform costs will be much lower than those of the Intel Core i7.

AMD, on the brink of making a start with its first desktop CPUs made on the 45nm manufacturing process, seems to have updated time-frames in which it will introduce new CPUs and manage inventories of currently available CPUs. Data compiled by DigiTimes from sources in the motherboard manufacturing industry points towards the following in 2009:

• The introduction of four new SKUs in the months of April, that include Athlon X4 (Propus core) 615 and 605, Athlon X3 (Rana core) 420 and 410, followed by Athlon X2 (Regor core) 240 and 235 in June
• Last orders for Phenom X4 9850 and 9950 (140W) to be taken in March, Phenom X4 9750, 9850 (95W) and 9950 (125W) will be in June, before which Phenom II X4 920 and 940 in May (in most likelihood replaced by models 925 and 945)
• Phase-out of Phenom X3 8450 and 8550 started, that of Phenom X3 8650 in March followed by Phenom X3 8850 and 8750 in June
• Last order notice for Athlon X2 4450e to be issued in March

BreakTheLimt.net, a Malaysian hardware portal tested the Phenom II X4 940 at its stock speed of 3.00 GHz, and posted a sting of benchmark results of the said chip. It was tested on a platform consisting of a MSI DKA790GX Platinum motherboard, with 2 GB of DDR2 1066 MHz memory and a ASUS Radeon HD 4870 TOP graphics card. All components were set to run at stock speeds. The chip was put through Super Pi 1M and 32M, Cinebench R10, PiFast Multithreaded, WPrime 1.5, Aquamark and 3DMark06.
