PB - RE: "Advanced Transfer Cache 256KB integrated L2 [Other Cascades products with larger cache] Full speed 256 bit wide data bus 8-way associativity Advanced System Buffering 6 fill buffers (up from 4) 8 bus queue entries (up from 4) 4 writeback buffers (up from 1) High throughput on read/store operations (11.7GB/s at 733MHz) Improved cache hit rate on read/store operations >4X lower latency on read/store operations Sustained bandwidth >1GB/s with 133MHz bus" I thought you spoke English! Translation for us folks not in the business please. All I know is "8-way associativity" is higher compared to Intel's L1 cache. And "Sustained bandwidth >1GB/s with 133MHz bus" doesn't matter much when combined with i810E.

PB - RE: "E" For the record, my "hubris" with the optimized Athlon SPEC scores is under the Assumption that particular Athlon estimated is not an Athlon Ultra. The slides didn't say Ultra. All the test configuration said was - "System Configuration AMD Athlon? Processor Hardware: 700 MHz, 650 MHz, and 600 MHz AMD Athlon processors 512KB L2 SRAM cache on processor module" It didn't say anything about the projected scores system configuration. But even if it turns out to be the scores of the Ultra, that performance is still impressive. BTW, AMD claims their L2 cache on the Ultra to be 16 way associative vs. "E"'s 8-way. But I assume it doesn't have "Full speed 256 bit wide data bus" because the cache isn't on the chip.
