    AMD today unveiled more industry-defining architectural features for its upcoming native Quad-Core AMD Opteron processors (codenamed “Barcelona”) during a presentation to the International Solid State Circuits Conference (ISSCC). In addition to the estimated 40-percent performance advantage native Quad-Core AMD Opteron processors can offer over the competition in benchmark testing, AMD’s redesigned microarchitecture will enable new power- and thermal-management techniques, strengthening the industry-leading performance-per-watt AMD Opteron processors currently deliver today. Among the new features are enhancements to AMD PowerNow! technology for dynamic adjustment of individual core frequencies.

    “AMD has always focused on delivering increased levels of performance without making compromises in power efficiency,” said Randy Allen, corporate vice president, Server and Workstation Division, AMD. “‘Barcelona’ will build on this value proposition while delivering industry-changing dynamics to the x86 server market, much like the original AMD Opteron processor did in 2003. New power management features, unique to the x86 market, combined with industry-leading performance and stability, make it clear why AMD remains the smarter choice for enterprises.”

    Optimum Power Consumption
    AMD is taking a multi-pronged approach to enabling reduced system-level power consumption for exceptional performance and low energy costs. Enhancements to AMD PowerNow! technology will enable systems based on native Quad-Core AMD Opteron processors to dynamically adjust frequencies at the individual core level for further power consumption reductions.

    Another new power management enhancement leverages AMD’s Direct Connect Architecture and integrated memory controller by enabling “Barcelona” processor cores to reduce voltage levels even while the memory controller runs at full speed. This enables the memory controller to service external memory requests independent from core p-state transitions, thus enabling p-state opportunities which can lead to additional power savings.

    The system memory interface also includes a feature that powers down memory logic when not in use. AMD has also made extensive use of “clock gating” in the “Barcelona” design to enable automatic shut-down of areas of logic not being utilized for further power savings.

    “Today’s IT system purchasers must weigh performance-per-watt as well as raw performance as they make their buying decisions,” noted Nathan Brookwood, Research Fellow at Insight 64. “By doubling the number of cores, adding a shared third level cache and applying a variety of other extensive CPU design enhancements, AMD’s ‘Barcelona’ designers clearly have addressed the numerator in the performance-per-watt equation. Today’s ISSCC disclosures reveal ‘Barcelona’ also includes innovations such as the ability to vary each CPU core’s frequency independently, along with a number of proven energy-saving techniques like ‘clock-gating’ that address the denominator in the equation. The combination of these new performance and power-saving features should drive a dramatic improvement in the already strong performance-per-watt AMD Opteron processor-based systems offer today.”

    Upcoming native Quad-Core AMD Opteron processors are designed for the same power infrastructure AMD customers depend on today - 68, 95 and 120 Watt thermal envelopes.

    Optimum Performance Levels
    While special attention was paid to the power-saving design features in native Quad-Core AMD Opteron processors, equal emphasis was placed on delivering industry-leading performance. Quad-Core AMD Opteron processors are packed with core and cache enhancements designed to improve performance on a range of server and workstation applications. Cache-sensitive transactional applications such as Web, database and email servers can benefit from the addition of a 2MB shared L3 cache. Simulations conducted in AMD laboratories indicate that certain database applications will see performance improvements up to 70 percent and certain floating point applications will experience performance gains of up to 40 percent over platforms powered by current dual-core AMD Opteron processors. High-performance computing (HPC) applications can benefit tremendously from a doubling of Barcelona’s floating-point execution pipeline to 128-bit width, which includes an AMD-only doubling of instruction and data delivery capabilities. Finally, through enhancements to AMD Virtualization™ (AMD-V™), including Nested Paging, virtualization customers can enjoy additional application performance improvements over non AMD-V driven applications.

    Availability
    Quad-Core AMD Opteron Processors are expected to be available in mid-2007.

    While this all sounds fantastic and I applaud AMD for supposed owning Intel with this proc release, how do we know for sure? I mean, are they comparing this with the Intel Xeon Quad core or the QX6700? IF amd delivers on these with a price to match, they may have a hit on their hands.

    these two don't compete...

    I wonder how amd's chip will REALLY perform. If it goes as well as they say it will i may be buying amd for my end of summer new pc. Also have to wonder how penryn will do in the 45nm shrink.

    amd have pwned intel for the last 6-8 years, while intel have jumped the gun and whooped amd with the conroe series chips i cant see amd bowing out and taking it hands down, which after all is good for all us hardware addicts because war means price war :toast:

    i actually prefer amd as it has been the most consistent performer over the last few years while i have built many a system but i am not a fanboy hence my e4300 on my current rig but i in a hardware sense grew up with amd, whatever packs the punch/price ratio is where im at ppl :toast:

    peace.

    Well if you want to look at most consistant performer it would actually be intel, amd has just recently really gotten into the spotlight. Both companies were created a year apart from each other and intel had a good 30 year run or so before amd even really became competition. Netburst seems to have been the only thing to hold intel back so far.

    Those seem like more or less server orienated, how would it work out in your standard everyday PC, or in a gaming machine? And which part of the compeition are they talking about?

    magibeg, that is an entirely unfair competition. It wasn't until very recently that AMD was creating their own chips; for a very long time, they were licensing and producing intel chips for less, such as the am286. It wasn't until the K5 that AMD began developing their own CPU technology and it wasn't until K7 that they launched their own socket interface.
