Athlon não acho gasto por que Pentium está ainda mais gasto...
Epá o grande Athlon continuará nos tops...
"Thanks to wlaote for digging up this article (German) discussing some details on ClawHammer from AMD's Jan Gütter. From the report, ClawHammer is apparently 20 to 25 percent faster than the current Athlon XP at the same clockrate in 32-bit applications. Applications compiled for x86-64 running in 64-bit mode exhibit an additional 15 percent performance increase, as has been reported previously.
Mr. Gütter also stated that power consumption should not be worse than it is with the Athlon XP, though it was not clear which processes he was referring to (ClawHammer will be on 0.13µ, but Athlon XP is currently on 0.18µ). He also stated that clockrate would become less important in the future because of Hammer's IPC improvement over the Athlon core, and that ClawHammer will initially sell at a premium over Athlon XP, but prices should fall over time.
Furthermore, Planet3DNow also had an opportunity to sit down with AMD Product Manager John Crank and ask a few questions here (German). There isn't much new information here, but Mr. Crank confirms that SledgeHammer will have up to 1 MB of L2 cache and a 128-bit DDR SDRAM memory interface. Multi-core versions of SledgeHammer were also denied to be in development."

"AMD has announced the official brand name of its upcoming 64-bit line of Hammer microprocessors: Opteron. Specifically, the new name refers to multiprocessor versions of Hammer, such as ClawHammer DP and SledgeHammer, but not uniprocessor versions. Uniprocessor desktop versions of Hammer (ClawHammer) will remain under the Athlon brand, though most likely with a suffix of some type to denote its 8th generation core. The Hammer-based Athlon is expected to be introduced in Q4 of this year, with the multiprocessor Opteron following in the first half of next year.
Additionally, the company has also announced an agreement with Microsoft to support a 64-bit version of the Windows operating system running on AMD's x86-64-based Hammer microprocessors. Furthermore, AMD will demonstrate a 64-bit version of Windows running on a dual-processor Opteron server tomorrow during its annual shareholders' meeting in New York City. In addition to the operating system itself, a variety of 64-bit and 32-bit Windows applications will also be shown running on the system. The development version of Windows to be demoed tomorrow will be a server version of the Windows codebase. This version of Windows does not have any specific optimizations with regards to Opteron's NUMA architecture, though AMD is confident that such optimizations will not be critical to performance and scalability given Hammer's low-latency memory controller and high-bandwidth HyperTransport CPU-to-CPU links. From the press release:
“Since the inception of the PC, hardware and software have been inextricably linked. The best advances in technology happen when the hardware and software are in sync. The union of AMD’s 8th-generation processor technology and a Microsoft Windows operating system built to support that technology lays the groundwork for broader industry adoption of 64-bit computing platforms, especially in the enterprise, and helps drive performance to stunning new levels,” said Dirk Meyer, group vice president of AMD’s Computation Products Group.
"At Microsoft, our vision for 64-bit computing is a highly scalable and affordable platform that is easy to deploy, easy to manage and easy to develop applications for,” said Dave Cutler, Sr. Distinguished Engineer, Microsoft’s Windows Team, and one of the world’s foremost software architects. “AMD’s 8th-generation architecture gives customers great 32-bit performance and 64-bit capabilities on a single system. Together, AMD’s 8th-generation processors and Windows should provide customers a flexible platform and a compelling value proposition.”
AMD's presentation on Opteron has been made available here in PDF format, and it contains some interesting details. Specifically, beginning on page 8 is a system diagram for an entry-level dual-processor Opteron system. This diagram seems to describe a dual-processor ClawHammer system, as you will notice the 72-bit (64-bit + 8-bit ECC) DDR SDRAM memory interface clocked at 200 MHz to 333 MHz (PC1600-PC2700). As we know, ClawHammer features a 64-bit memory interface, while the high-end SledgeHammer has a 128-bit memory interface. On page 10, you can see a description of a four processor Opteron server with a 144-bit memory interface (128-bit + 16-bit ECC). A dual-processor workstation configuration for SledgeHammer/Opteron can be found on page 11.
Another interesting detail seen in this presentation is the difference in the bandwidth of the coherent HyperTransport links used for multiprocessor configurations. Specifically, it seems the dual-processor Opteron uses 3.2 GB/s cHT links between processors (1.6 GB/s each way), while the quad-processor Opteron has 6.4 GB/s cHT links (3.2 GB/s each way).
Continuing, on page 13 there is an interesting note regarding the performance improvements associated with the Opteron architecture over that of the Athlon. Specifically:
Note: the AMD Opteron processor is planned to provide 20- 25% better performance than the AMD Athlon ™ processor -- 20% from on-chip low latency memory controller and 5% from improvements on processor core.
So, apparently, the 20 to 25% performance increase over Athlon that has been reported in the past is primarily due to the integration of the memory controller onto the processor itself. The additional 5% performance improvement would seemingly not include any improvements resulting from the use of x86-64 (indicated to be roughly 15%), if previous statements hold true.
As reported in the past, the Opteron processor will include up to 1 MB of L2 cache, with the dual-processor version presumably featuring 512 KB. Moving on to page 15 of the presentation, we see a roadmap placing the uniprocessor Athlon-branded Hammer in line for a fourth-quarter 2002 introduction. The multiprocessor Opteron for the server and workstation segment is scheduled for the first half of next year.
AMD's 8th generation Hammer-based processors will be manufactured at the company's Dresden Fab30 facility on an 0.13µ SOI process. "Barton," the company's 0.13µ Athlon XP with 512 KB L2 cache will be outsourced to UMC, and it will not be produced on an SOI process. Barton, which is expected to make its debut during the second half of this year, will become a low-end solution for AMD, taking the place of the current Duron processor. Finally, the 0.13µ version of the Athlon XP, codenamed Thoroughbred, remains on-track for an introduction during the first half of this year. "

Portanto pela leitura não vais ser um mero CPU de 64bits, SSE2 e uns pozinhos como se diz por aí...
"So, say it again, Opteron. Opteron from the Latin optimus meaning best..."

Ou seja era como a Intel quando lançou o Celeron que em pretuguê quer dizer que é também é rapido... estes gajos devem ser doutores em fillogia e essas coisas de latim, porque até agora todos os nomes dos CPUs vêm de Latim...
O nome não me interessa... eu quero desempenho duro...
