Hi guys. So I'm trying to answer the age old question "Just how much slower is the K6-III compared to intel's Pentium II and Pentium III CPU's?" so I put my K6 machine against a 500MHz P2 and a 500Mhz P3. As you know, there's no such thing as a 500MHz Pentium II, so I overclocked my 333Mhz SL2TV to 500Mhz by running it at FSB 100 and 2.3V. I should have ran the K6-3 at 500MHz as well, but commodity got the best of me. Things ballance out a little tough since the intel machine uses a faster Diamond Monster Fusion card witch is clocked at 105 MHz core / 120MHz memory vs the 100 / 100 MHz Creative 3D Blaster in the K6.
1. Test Systems
AMD Machine:
CPU: AMD K6-III+ 400ADZ 1.6v @ 550Mhz 1.8v
Mainboard: Aopen AX59PRO VIA MVP3 2MB cache, ATX format -> http://www.motherboards.org/mobot/motherboard … pen/AX59%2BPro/
RAM: 2x128MB Micron 100MHz CL2 (compaq OEM)
Video: Creative Voodoo Blaster Banshee 16MB SGRAM AGP, 100MHz core, 100MHz memory -> http://hw-museum.cz/view-vga.php?vgaID=24
Sound: Yamaha DS-XG YMF754
Intel Machine:
CPU1 - Intel Pentium II (Deschutes) 333MHz SL2TV overclocked to 500MHz (FSB 100, 2.3V, IOQD8 )
CPU2 - Intel Pentium III (Katmai) 500 MHz
Mainboard: Abit BE6-II V2.0 Intel 440BX -> http://www.motherboards.org/mobot/motherboard … t/BE6-II%2B2.0/
RAM: 2x128MB PQI 133MHz CL3
Video: Diamond Monster Fusion 16MB SGRAM AGP 105MHz core, 120Mhz memory -> http://www.vgamuseum.info/index.php/component … -voodoo-banshee
Sound: Yamaha DS-XG YMF754
2. Software used:
- Aida64 2.5
- Speedsys 4.78
- 3DMark 99
- GL_Quake
- Quake 2 3.20
- 3dfx MiniGL v1.46
- Creative and Diamond drivers based on the 10300 3dfx banshee drivers (Diamond Fusion 213 and Creative Drivers 1.19, both released in 1999)

4. Test results:
As expected, the super socket 7 rig has the slowest memory speeds out of the 3 setups, but this thread is about FPU and 3D performance. Despite it's low memory scores, the K6 manages the highest Speedsys score as well as the highest CPU Queen scores out of the 3 machines. In fact, it beats Finalwire's 600Mhz Duron by a small margin! It also has the best FPU julia score, edging out the Katmai by 9 points. Keep in mind that these are not clock per clock results - if it were, the K6-III+ @ 500Mhz would be trailing the Katmai slightly.
The P3 is the best performer overall, but the K6 isn't far behind. In fact, it's very close in 3Dmark - both CPU and Graphics tests, even tough the Intel setup was tested using a faster video card. It also holds it's own in Quake 2, beating the overclocked Pentium II and trailing the Pentium III by a meager 0.6 fps. GL_Quake favours the Pentium II for some reason, but that's the only test the PII leads. The K6 is the worse performer in GL_quake, losing to the Pentiums by about 6 FPS.
Direct 3D Performance:
3DMark doesn't seem to like the Pentium 2 for some reason. No amount of tweaking would increase the result above 4500 points in the CPU test witch I find suspicious. Even lowering latency, setting in-order que depth to 8 and increasing voltage did not help the PII in this test. The P3 emerges the clear winner here - most noticeably in the First Person Shooter test.
Speedsys again favours the K6-III with a score of 626.7 because it's more frequency sensitive. The test isn't very relevant here, and the difference between the P2 Deschutes and P3 Katmai is a meager 2 pts. I'm quite certain the K6-3 at 500Mhz would have scored in the same ballpark as the pentiums, if a tiny bit faster.
Aida64's Cache and Memory Benchmark shows the K6-III and the P3 have similar cache system performance - the K6 being slightly faster due to the extra 50MHz. Memory speed is another story. The super 7 platform is showing it's age with these poor memory results.
That's about it for now. Here -> http://imgur.com/a/jRQ8N you can find pictures of the quake benchmarks, 3dmark screenshots, as well as Aida64 scores and some other stuff relating to the tests. Hope you enjoyed reading this as much as I enjoyed making it!
