So, a couple weeks ago I ordered a K6-2+ 500 off of eBay for my Super7 system "Titania". It originally had a K6 266MHz in 1998 but it's had a K6-2 500 in it since early 2001. I've always been curious what real world performance that the K6-III and K6-2+/III+ chips offered over the original K6's, but never got around to actually getting one until recently because they're hard to find. Most here likely know but for those who don't, the K6-2+ is a cut down K6-III+ with 128k on-die L2 Cache instead of 256k. From what I've heard there isn't a huge difference between the II+ and III+ so I wasn't worried about getting the cheaper chip, though I'd love to have a faster one for my collection in the future.
Anyway, while I had the SS7 system apart, I decided to do a bit of Benchmarking using Quake II and 3DMark 2001se.
So, here are the results, what you're about to see is the result of hours of possibly pointless work and testing:
Test system specs:
FIC VA-503+ BabyAT Super7, VIA MVP3 Chipset, 1MB L2 Cache, JE4333 BIOS (support for K6-2+/III+)
256mb PC100 RAM (2x128)
6.4GB Fujitsu MPC Hard Drive
3DFX Voodoo3 2000 16mb AGP (3DFX v1.07 Driver)
15" Dell LCD Monitor (1024x768@75Hz)
Windows 98 Second Edition.
Software Setup:
MadOnion 3DMark2001 Second Edition, full version.
Textures converted to 16bit during install, as the Voodoo3 supports maximum 16bit colour.
Quake II v3.20 with 3DNow! Patch.
Added "+set s_initsound 0" to shortcut to disable sound.
Tests run on the included demo tests, Demo1.dm2 and Demo2.dm2, 3 runs on each.
All tests run at 1024x768.
= K6-2 500MHz =
Quake II:
Demo1.dm2: 54.7 / 54.9 / 54.9
Demo2.dm2: 55.4 / 55.7 / 55.8
I ran 2 runs of 3DMark 2001 SE to be sure. The tests are excruciatingly slow, so I ran only 1 run each from here on.
= K6 300MHz (3x100) =
This chip is actually my original K6 266MHz 2.2v chip from 98. I knew I could overclock it to 350 at normal voltage/cooling on 100MHz FSB, so instead of screwing with the gawdawful amount of jumpers on the VA-503+, I went lazy and just set it to 3x100 and ran the test.
Quake II:
Demo1.dm2: 32.0 / 32.2 / 32.2
Demo2.dm2: 31.9 / 32.1 / 32.1
This one was fragging slow, eeesh!
= K6-2 300MHz (3x100) =
For fun, to draw a comparison of how much difference there was between the K6 and K6-2, I dropped in my K6-2 333 chip from my CPU collection and left the 3x100@2.2v the same. I found the performance difference surprising!
Quake II:
Demo1.dm2: 44.0 / 44.5 / 44.3
Demo2.dm2: 44.1 / 44.3 / 44.5
Unfortunately I forgot to grab a screenshot of the 3DMark2001 results, but I did write them down.
SCORE: 414
Now for the moment I'd been waiting for, the K6-2+!
= K6-2+ 500MHz =
Quake II:
Demo1.dm2: 67.0 / 67.0 / 66.9
Demo2.dm2: 64.9 / 65.4 / 65.4
I also ran the Quake II tests with the 3DNow! enhancements off.
Demo1.dm2: 59.6 / 59.9 / 59.9
Forgot to run Demo2.dm2, but you get the idea. The K6-2+ results with 3DNow off are faster than the K6-2 with 3DNow on.
These results I thought were fantastic. about a 10FPS increase in Quake II and a big boost on 3DMark just by adding a little bit of L2 cache. In the end, I'd have to say that anyone who's considering building a K6-2 based system, that upgrading it to a cheap K6-2+ (I got mine for 12$) is a worthwhile upgrade for that extra boost in performance, especially when there are games that'll put much more of a strain on the system than Quake II. Just be sure your board can supply 2.0 volts and has a patched BIOS available for K6-2+/III+ support.
And for sh*ts and giggles, I threw my Slot A Athlon "Titania-II" up on the bench.
Specs:
FIC SD11 Slot A Motherboard (AMD 751+VIA 686A)
512mb PC100 RAM (2x126+1x256)
20GB WD200BB 7200RPM HDD
3DFX Voodoo3 3000 16mb
Windows XP SP2
Athlon 550MHz (0.25um Argon)
Quake II:
Demo1.dm2: 83.6 / 84.2 / 84.2
Demo2.dm2: 84.7 / 84.8 / 84.6
Then, I installed the 3DNow patch, ran it again.
Demo1.dm2: 84.2 / 84.2 / 84.2
Demo2.dm2: 84.9 / 85.0 / 84.9
Originally I had 3Dhq 1.09beta drivers installed, however, 3DMark crashed when running, probably a buggy D3D Driver. So I uninstalled them and installed AmigaSport v3.0f for Voodoo3 cards. I reran the Quake II tests, but this had the unfortunate side effect of locking out the V-sync, so all tests pretty much came at around 75fps, due to the 75Hz refresh rate. However, the 3DMark test did run.
Athlon 700MHz (0.18um Orion)
I popped in another Slot A chip I had lying around for testing, I had to blow on it like an NES cart, but it worked. Unfortunately the QuakeII tests were eschewed due to the refresh rate, but the 3DMark01 test ran fine.
And just to put everything in perspective, I ran the tests on my Main PC.
Specs:
AMD Phenom II X6 1090T (6 Core, 3.2GHz with 3.6GHz Turbo)
Asus M5A88-E AM3+ AMD880G mATX Board
16GB (4x4) DDR3-1600 Kingston HyperX Genesis RAM
500GB Seagate 7200.11 SATA2 HDD
Sapphire 512mb ATI Radeon 4850 PCIe
Quake II:
Demo1.dm2: 804.9 / 793.8 / 903.0
Demo2.dm2: 682.9 / 886.7 / 886.7
How far we've come. Thanks for reading!
