“HP ENVY includes the latest in materials and technology inside and out and pushes the technological and performance boundaries of what can be done in sleek, powerful and lightweight notebook PCs,” said Ted Clark, senior vice president and general manager, Notebook Global Business Unit, Personal Systems Group, HP. “Discerning consumers will get a premium experience and performance.”

Triplex Designs Radeon HD 4830 Without Auxiliary Power Connector

A relatively unknown company, Triplex, has designed a Radeon HD 4830 graphics accelerator that does not require the 6-pin PCI-Express power connector. This is especially interesting for two reasons: that it is RV770, and that it runs at reference clock speeds despite shedding its traditional power design. Spotted on XtremeSystems, this engineering sample PCB features a 2+1 phase power design, that draws all its power from the PCI-Express slot.

Also featured are 512 MB of 256-bit GDDR3 memory, DVI-D, HDMI and D-Sub outputs, and a seemingly two-slot cooler design that is yet to be pictured. The card lacks CrossFireX fingers. The GPU has 640 stream processors, DirectX 10.1 compliance, and a 256-bit memory interface. It has AMD reference clock speeds of 575/900 MHz (core/memory). For reference the third picture shows a Radeon HD 4670 accelerator of the same make, and PCB length.

Radeon HD 4750 Previewed, Performs Closer to HD 4850

An unexpected visitor to Guru3D.com's offices was a pre-release sample of a yet to be released 40 nm RV740-based Radeon HD 4750 graphics accelerator. Not bound by any NDAs with AMD, the website went ahead with a little (p)review of the card. The HD 4750 is the RV740XT model, and features GDDR5 memory. The name contradicts an earlier report suggesting HD 4770 to be the shelf-name for the RV740XT, and HD 4750 for the GDDR3-based RV740Pro. It features 640 stream processors, core clock speeds between 650~700 MHz and GDDR5 memory clocked at 800 MHz (3.20 GHz effective), across a 128-bit wide memory bus. The RV740XT comes with a rated shader compute power of 900 GFLOPs, as against 740 GFLOPs the RV770LE-based HD 4830 is rated at, while having similar specifications. It comes with 32 TMUs and 16 ROPs.

The findings of the preview show it to be somewhere between the performance levels of the Radeon HD 4830 and HD 4850. Interestingly, Guru3D omitted GeForce 8800 GT/9800 GT from the comparison, though GeForce 9600 GT was left to face the onslaught from stronger ATI GPUs. The Radeon HD 4750 is expected to be priced below the $100 mark and is expected to outperform most competitive accelerators in its price-range. To read the review, head over to Guru3D here.

NVIDIA Preparing GeForce 9800 GT Green Edition, Readying GTS 200 Series

NVIDIA is going ahead with the launch schedule of the GeForce GTS 200 series, that consist of products based on the current-generation G92 GPU. It is known that the GTS 240 and GTS 250 are re-branded 9800 GT and 9800 GTX+ respectively. The 9800 GTX+ SKU will officially be renamed GTS 250 on March 3. One can expect NVIDIA partners to come up with cheaper SKUs that fit into the US $ 130 range, lower than the current $150 range 9800 GTX+ and ATI Radeon HD 4850 compete in.

The GTS 240 on the other hand, will be introduced soon with a newer price-range of around $100, lower than the $120 mark the 9800 GT revolves around. This should make it more competitive against the Radeon HD 4830, which is currently winning in the price/performance figure. Additionally, the company is preparing a GeForce 9800 GT Green Edition, which carries forward the design methodology of the 9600 GT Green Edition: lowering the GPU voltage and slightly reducing the clock speeds. It is expected to carry clock speeds of 550/1375/900 MHz (core/shader/memory) against the reference 9800 GT specifications of 600/1500/900 MHz. The new SKU might be priced at a premium over the GTS 240, at around $ 120.Source: VR-Zone 1, 2

More XFX Radeon Series Graphics Cards Pictured

It does come as a surprise to us, that XFX is going to have a full-fledged non-reference design ATI Radeon lineup, barely a month into its official announcement of a tie-up with AMD. Pictured below are XFX Radeon HD 4350, Radeon HD 4650 and Radeon HD 4830. Ideally XFX will use a common design with its Radeon HD 4600 series cards. Both incorporate black-coloured PCBs, and the XFX colour scheme with the coolers.

The XFX Radeon HD 4350 (model: HD435X-YAH2) comes with a core clock speed of 600 MHz and 512 MB of DDR2 memory clocked at 1000 MHz. It is passively cooled and is low-profile friendly. The XFX Radeon HD 4650 / HD 4670 cards use reference AMD clock speeds. The Radeon HD 4850 card comes in two variants, HD465X-YAF2 (512 MB) and HD465X-ZAF2 (1 GB). Also pictured is the XFX Radeon HD 4830 512MB (model: HD483X-YDFC) that looks identical to the XFX Radeon HD 4850, pictured earlier.

RV740 a 40nm RV770LE in Disguise?

RV740, the first GPU built by AMD on the 40nm silicon fabrication process, seems to be gaining attention. While earlier reports suggested this core to be simply a miniaturized RV730, a fresh report emerging from VR-Zone says otherwise.

The RV740 is supposed to be largely derived from the RV770, as in its RV770LE avatar which went into making the ATI Radeon HD 4830. There are some interesting specifications attached to it. To begin with, the core physically holds only 640 stream processors, in comparison to the 800(+) on the RV770. The core continues to have 32 texture memory units (TMUs) and 16 render back-ends. Interestingly, there is a 128-bit wide GDDR5 memory bus instead of 256-bit wide GDDR3 (for the RV770LE). With this, the RV740 has a rated memory bandwidth identical to that of the RV770LE, 57.6 GB/s, though the bus width would warrant the use of lesser number of memory chips, and effectively reduce manufacturing costs. Graphics cards based on this GPU are expected to emerge in early 2009. You can also expect derivatives based on this core with GDDR4, GDDR3 or even DDR2 memory. In any case, the products are expected to cost below US $100.

HIS Ready with HD 4830 IceQ-4

Almost a month into the launch of the ATI Radeon HD 4830, HIS is ready with its IceQ-4 model. The graphics card uses the Radeon HD 4830 at reference speeds of 575 MHz, and features 512 MB of GDDR3 memory running at 1800 MHz. The card uses the same exact PCB and cooler design, as that of the Radeon HD 4850 IceQ-4, since the GPU is pin-compatible, but the heatsink over the VRM area is lacking.

As with other ATI graphics cards in its cadre, it provides audio-routed HDMI via a dongle, ATI CrossfireX multi-GPU technology, and DirectX 10.1 support. The card is expected to hit stores soon, carrying a price-tag of €140 in Europe.

NVIDIA Responds to Radeon HD 4830 Launch, Claims GeForce 9800 GT is Better

NVIDIA has issued a slide-show, a consolidated presentation taking into account, the findings of some review sources. In short, NVIDIA claims that the GeForce 9800 GT is not only faster than Radeon HD 4830, but also that its value-added features such as the CUDA HPC foundation and PhysX acceleration amount to a superior product all in all. Donanim Haber got their hands on this slide-show before anyone could, so here goes: GeForce 9800 GT vs. Radeon HD 4830 - a presentation by NVIDIA.

AMD Responds to TechPowerUp Investigation, Issues Remedy

Earlier this week, when evaluating samples of the new Radeon HD 4830 GPU-based graphics card, W1zzard, who also authors the GPU-Z diagnostic utility, had found an anomaly with the stream processor (SP) counts on samples sent by AMD. The GPU could access only 560 out of its 640 SPs available. This affected the card's performance significantly, and TechPowerUp's findings were validated by several other reviewers with similar samples.

AMD on its part quickly followed up the issue with its engineering department, and released a video BIOS update that fixes the issue and makes available all the 640 SPs. AMD will be circulating this BIOS to all its press contacts and add-in-board (AIB) partners, to make sure the issue is isolated and fixed. The updated BIOS file can be downloaded from here. AMD also asserts that the issue isn't hardware related, and that updating the BIOS resolves the issue completely.

Shader-deficient Radeon HD 4830 Could be in the Channels

The ATI Radeon HD 4830, the newest foot-soldier from the red-camp, is AMD's answer to the GeForce 9800 GT, a gap left by the company, that may have been eating into its profits for months now. As usual, TechPowerUp received its review samples from TUL (PowerColor), AMD's long-standing partner, and AMD itself. We reviewed both of them, as soon as the product became official today. During the course of reviewing them, with the card from AMD in particular, our reviewer, W1zzard noticed an anomaly: the sample from AMD was showing an abnormal stream processor count of 560.

W1zzard also authors the GPU-Z diagnostic utility, and it is his routine chore to program the utility to detect a new GPU. The newest build of GPU-Z detected the card from AMD to have as many as 80 stream processors disabled from the original specifications for the Radeon HD 4830. In his article, W1zzard attempts to explain this anomaly.

AMD Launches ATI Radeon HD 4830 Graphics Card

The ATI Radeon HD 4830 continues that great trend, providing tremendous value to gamers for less than $150.”

HIS Radeon HD 4830 Pictured, Looks Familiar

HIS is ready with its newest graphics card, based on the upcoming Radeon HD 4830 graphics processor, and what do you know? It looks identical to the HD 4850 Fan the company released earlier. This can be attributed to the fact that the RV770 LE GPU uses the same pin-layout as the HD 4850, and uses the same memory sub-system (256-bit GDDR3). The only difference comes with the newer GPU featuring 640 stream processors, and slightly lower clock-speeds of 575 MHz (core) and 1800 MHz (memory).

The card features a blue PCB with a 2 phase power circuit, it features 512 MB of GDDR3 memory. It uses a simplistic GPU cooler, with a blue LED-illuminated fan. The card supports 4-way CrossfireX. It is expected that the card sells for a price between US $140 and $150.

Slides Reveal Radeon HD 4830 to be Tougher than Expected

Performance projections for the upcoming Radeon HD 4830, made news yesterday, where it is projected to outperform the GeForce 9800 GT. Two new slides published by VR-Zone shed light on how the RV770LE graphics processor manages to do that, and there's a surprise: It was earlier known that the RV770LE comes equipped with 480 stream processors, and one of the earliest reports even suggested that it could have a narrower 192-bit memory bus. The slides published, show that the new GPU could carry as many as 640 stream processors, double that of the RV670. It comes with a proper 256-bit wide GDDR3 memory bus. Also included, is hardware support for 24x custom filter anti-aliasing (CFAA).

It is also known that the new card is gearing up for an October 21 launch and would be priced below US $150. AIBs would be able to sell custom designed cards right upon launch. While the new GPU does look "tougher" and more equipped than expected, here's something to ponder: with twice the amount of stream processors as the Radeon HD 3870, as projections suggest, is it going to be only 10% faster than the 9800 GT?

Radeon HD 4830 Projected to Outperform GeForce 9800 GT

As reported earlier, AMD is preparing a scaled-down version of the RV770 graphics processor, called RV770LE. The new graphics core would go into making the Radeon HD 4830 SKU. The new graphics core was created to compete with the GeForce 8800/9800 GT, which seem to be in a comfortable market position owing to their price and price/performance. They are comfortably placed between the GeForce 9600 seties and the 8800 GTS 512M/9800 GTX/GTX+.

AMD has already started projecting the HD 4830 to outperform the the G92GT, in essence, the GeForce 9800 GT. In a slide titled "Best Graphics Card for <$150", the company puts up figures where the new card is projected 10% faster in most games tested. The only glitch, is that most of AMD's own increment projections are based around that 10% mark, which means it could be a very tight contest between the HD 4830 and 9800 GT. A prelude could be that for the 9800 GT, its CUDA and PhysX processing capabilities could bail it out, if it does fall into a tight spot, as in, if the two end up in a neck and neck contest. The new Radeon accelerator comes out sometime next month.

ATI Radeon HD 4830 to be Launched this October

At this point, ATI has a product to counter NVIDIA in every segment barring some gaps, such as the GeForce GTX 260 (216 SP) at $299 and the GTX 280 itself at its low price, GeForce 8800/9800 GT in their price ranges and the GeForce 9600 GSO.

The entry of Radeon HD 4850 X2 aims to disturb the market position of the GeForce GTX 280. To compete with the 8800/9800 GT and 9600 GSO, ATI is preparing a new down-scale graphics processor called RV770LE. The GPU has 480 stream processors and carries the brand name Radeon HD 4830. It will sport 512 MB of GDDR3 memory. Upon launch, ATI's partners would be free to launch it at speeds that suit their product lines. This GPU launches sometime in October.Source: VR-Zone
