Dr. Engel: <<It is competition for the K6-3 because Mendocino may outperform - or at least match - a K6-2.>> A PII with cache at half speed can't even match the K6-2 clock for clock when playing games with 3DNow or even chess. bootnet.com GLQuake II....333MHz-K6-2.....333MHz Pentium II 640x480.......71.3fps.........68.8fps 800x600.......71.3fps.........62.0fps 1024x768......62.2fps.........44.7fps Another similar findings hardware.pairnet.com "....While 1024x768 was slower than 640x480, it is still almost 80 frames per second! Personally, I am more than happy to give up 3 frames per second to enjoy 1024x768. From what I have been told, the Pentium II consistently takes a near 20 fps loss by going to 1024x768. 3DNow! is giving the K6-2 a dominating lead over the Pentium II when running 1024x768 with a pair of Voodoo 2 cards...." This is due to the fact that the bottleneck of the PII system is the CPU. The PII couldn't keep up with 3D calculations. A Xeon is a PII with L2 cache running at full speed is only 1-2% faster than PII www2.tomshardware.com In games like QuakeII or many of the 3D games the speed of L2 cache is not as important as in 3D calculations. Thus Xeon WILL NOT OUTPERFORM K6-2 clock for clock. A Mendocino is just a PII with integrated 128K L2 cache. Mendocino is NOT FASTER than Xeon clock for clock. Thus there is no way Medocino will outperform K6-2 running 3DNow applications. You put too much hope on the Mendocino and Celeron. With the new price cut AMD didn't react to Intel's Celeron pricing. The K6-2 ASP is still at healthy above $100 level. The bottom line is that Intel doesn't have a CPU that can do 4 FLOPS per clock cycle. Dream on. Maxwell
