<I have heard that Intel CPU's with full speed caches do not show much performance improvement over their half speed counterparts, for desktop benchmarks. Can anyone confirm or deny these rumors?> For Deschutes, this is true. Check out: tomshardware.com For single-threaded benchmarks, Pentium II Xeon shows no noticeable improvement over Pentium II. Also, for multithreaded tasks in Windows NT that doesn't exercise the processor bus, once again there is little improvement. However, one benchmark caught my eye. Running Highend Winstone 98 with a 1.2 GB file compression task AND an AVI video playback occuring concurrently shows a 16% improvement from Pentium II to Pentium II Xeon. As Tom himself states, "Xeon shows its superiority if there's really heavy traffic on the buses." I'm sure the improvement would have been even better if Tom ran any server benchmarks, but of course, we all know that Tom Pabst isn't interested in servers. Tenchusatsu

Scumbria, here's another Xeon vs. Pentium II benchmark from Maximum PC Magazine. The Gateway GX-450XL 450 MHz Xeon at $3,999 was reviewed in the December issue. The Dell Dimension XPS R450 ($2,917), in the November issue. Benchmark: _____Dell P2-450__________Gateway XEON 450 Synthetic CPU______209 ______________________223 (+7%) Windows APPS_____185_______________________193 (+4%) 3D Rendering_______492s______________________473s(+4%) Photoshop Test_____ 71s______________________ 70s(+1%) QuakeII FPS________57.5_______________________62 (+8%) Conclusion on the Gateway "Goodies galore -- Xeon's a bore" Petz

Scumbria - Re: "I have heard that Intel CPU's with full speed caches do not show much performance improvement over their half speed counterparts, for desktop benchmarks." Available benchmarks - try Tom Uberclockermeister - show that the Mendocino - a 128 K full CPU speed L2 Cache Celeron - performs almost as good as a Pentium II with 512K half-CPU speed L2 cache, when the Mendocino and Pentium II are clocked at the same speeds. Conclusion - SMALL FULL SPEED caches can provide enough performance as a half speed cache FOUR TIMES the size ! Paul
