<"Daiki knows of someone who chunked faster SRAM ("this Athlon is Athon500@835 with DDR-SRAM Full speed L2 :)") of some sort in place of the L2 on a 830MHz (overclocked) Athlon. Reportedly, the latency of the cache was 23 cycles. According to Daiki, performance with this was very fast, allowing the Athlon to outperform the Coppermine even in the "Athlon-killing" Super-Pi benchmark .... If this is true, it's very promising. The Thunderbird will have far superior caching compared to this setup, as the latency will be probably better than halved (and hopefully, the cache bandwidth will be improved, but even without that it should be fairly sweet). More on this later, I guess. :) > By the time Thunderbird/Spitfire get into volume production (est. Q2), CuMine should have some robust support on the chipset side but a good Athlon chipset with DDR can do wonders. The real upside I see here is the on-die L2 cache: Low latency victim caches should do wonders to Athlon derivatives. I fancy musing that SpitFire will benchmark favorably with CuMine.

Samuel - RE: "According to JC's News:" Ahh, yes. Signs of the Athlon getting faster and faster. First comes KX133, then on-chip cache, then mustang and its faster RAM and fsb.

Samuel, digital.com This link from JC's is a nice read. The DEC technical marketing guys seems to have done a good job. It is long but I recommend it for the technically oriented folks on this thread. IA-64 is entering a new world that was not quite what Intel had in mind when the program began. If I look at the roadmaps from AMD and Intel that are being thrown around, there is a chance that there will be substantial enhancements or new cores every 6 months starting with Athlon all the way through end of 2001. IA64 derivatives may just not able to keep up with this kind of pace. Chuck
