Re: "You better tell us how many spins it took for Intel to make the 440BX chip." Ali, what makes you think it took any "spins" to fix it? What is your estimate? How many do you think it took? EP

Some interesting tidbits regarding the benefits of moving to PC66 to PC100: www4.tomshardware.com www4.tomshardware.com www4.tomshardware.com www4.tomshardware.com I looked at Tom's trusty CPU benchmarks again, and I saw that he also ran some tests on a Celeron 400 which wasn't multiplier locked. He ran that Celeron both on a 100 MHz bus (4x multiplier) and on a 66 MHz bus (6x multiplier). Comparing these two configurations can provide us a good look into the benefits associated with increasing the bus speed from 66 MHz to 100 MHz. First of all, the bad news. For a Celeron running at 400 MHz, going from PC66 to PC100 SDRAM provides a 1.9% improvement in Business Winstone 99 under Windows 98, and a 6.7% improvement in the same benchmark under Windows NT. That's it for a 50% increase in SDRAM speed. Now the good news. Highend Winstone 99 did better, a full 15.0% improvement. And Dragon's Naturally Speaking 3.52 showed a whopping 23.3% improvement! It seems to me that these two benchmarks are highly dependent on memory bandwidth. Now why do I bring this up? I bring this up so that we can predict what performance benefits might come from a transition from PC100 to PC133 SDRAM. Going from PC66 to PC100 is a 50% increase in memory bandwidth, but going from PC100 to PC133 is only a 33% increase. Obviously, there should be only miniscule improvements in Business Winstone 99, significant improvements in memory-intensive tasks like Highend Winstone 99 or Naturally Speaking, and almost no improvement in games since they're even less memory-intensive than Business Winstone. Pretty complicated picture, no? Tenchusatsu
