Dan, <P4 has a short latency 2 cycle L1 cache, while AMD has a 3 cycle L1. Since AMD's design allows more time to access the L1, it can operate at a higher frequency - think of it as a long pipeline "netburst" style L1 cache.> Maybe you forgot that Athlon's L1D cache is eight times the size of Pentium 4's L1D cache. There is no way on Earth that Athlon's L1D can run "at a higher frequency" than that of P4. But I'm sure things work a little differently on your planet ... Tenchusatsu

still doesn't make sense. if it takes 2 cycles to access the cache at 2.2ghz, it can be said that the cache is running at 1.1ghz. if it takes 3 cycles at 1.6ghz, it means the cache is running at 533mhz. the question is "what's the smallest period where you can get one word out of a cache?". i think that number is smaller for p4 than athlon.

Intel (Nasdaq: INTC - news) -- Best PC Processor of 2001 biz.yahoo.com Wednesday February 20, 8:09 am Eastern Time Press Release SOURCE: Cahners In-Stat/MDR Cahners In-Stat/MDR Announces Intel and Texas Instruments as Recipients of Microprocessor Analysts' Choice Awards SAN JOSE, Calif.--(BUSINESS WIRE)--Feb. 20, 2002--Cahners In-Stat/MDR (MicroDesign Resources), publisher of the Microprocessor Report, Wednesday announced the fourth and fifth category winners of its fourth annual Analysts' Choice Awards, honoring the best new microprocessor chips and most promising new microprocessor technology unveiled in 2001. In-Stat/MDR's Analysts' Choice Awards, awarded this year in 10 categories, recognize excellence in semiconductor technology innovation, design and implementation. The awards will be formally presented during the week of the Embedded Processor Forum (http://www.mdronline.com/epf), April 29-May 2 in San Jose. The winners (in alphabetical order) in the following categories are: Intel (Nasdaq: INTC - news) -- Best PC Processor of 2001 Texas Instruments (NYSE: TXN - news) -- Best DSP Chip of 2001 Of the PC processors to ship in 2001, Intel's Pentium 4/Northwood has top scores on a large number of benchmarks, including SPEC; the highest clock frequency; more bus bandwidth; has chip set support for three memory types; and was fabricated in advanced 0.13-micron semiconductor process a quarter ahead of its closest competitor. For these reasons, we give Intel's Pentium 4/Northwood the Microprocessor Report Analysts' Choice Award for Best PC Processor of 2001. This award for Northwood also recognizes the significant contributions of the Pentium 4 in 2001: the first 2GHz processor, SSE2 instructions, and accessible pricing. The VLIW processor is certainly the most intricate DSP architecture available in 2001. Despite its complexities, TI's design techniques and excellent manufacturing capabilities allow the company to offer a 600MHz machine. Although it runs at twice the operating frequency of the C62x products, the C6414 consumes roughly half the power. MPR believes TI's claims its EEMBC Telemark is substantially better than that of its 300MHz C6203 (with a Telemark of 68.5), even after normalizing for frequency. Combining the TI's C6414's performance and power with the architecture's roadmap, overall value, and development tools makes this device the winner of the Microprocessor Report Analysts' Choice Award for Best DSP Chip of 2001. Each year, Microprocessor Report analysts review and evaluate more than 100 microprocessors, digital-signal processors, and application-specific digital machines.
