Hi retro enthusiasts,

I'm the owner of the following system:
-Gigabyte GA-5AA motherboard rev 3.2
-Chipset ALI Aladdin V @ 100 MHz
-AMD K6-2 @ 550MHz
-Noname sd -> ide adapter
-Asus Voodoo 3 3000 AGP
-128MB PC133 @ 100MHz
-Crystal ISA soundcard

The thing is, i think it is underperforming. There are more threads about this topic, but not with the normal K6-2. I hope there are more owners of this motherboard, to compare the results of some benchmarks.

1: Speedsys
Memory bandwith: 352 MB/s
Vesa memory: 83525 MB/s
CPU score: 631.00
Data cache L1 (32KB) 2505.92 MB/s
Data cache L2 (512KB) 317.38 MB/s
Memory Throughput 172.87 MB/s

2: 3dMark99 640x480 tripple buffer (16 bit colors)
2304 3DMarks
6715 CPU 3DMarks

3: Final reality Default settings No sound
3.35 Reality marks

4: 3DMark 2000 640x480 tripple buffer (16 bit colors)
1247 3DMarks

Anyone experiencing the same results?

Operating System?
Size of external cache?

It may be likely that just 64 of your 128 MB SDRAM are inside the cacheable area of your external cache.

Operating system is windows 98se.

The size of the external cache is 512KB.

I will try 64MB RAM.

You also can try this tool from heise's famous c't magacine to measure cacheable area:

Thanks, i did try this and there are no non-cacheable area's found. The board can cache the full 128MB ram.

I will try and test a voodoo banshee and voodoo 2 sli, maybe a tnt2 to compare results.

Update on the benchmark of another videocard: Voodoo Banshee with same settings in each benchmark like used with the voodoo3 3000

3DMark99:
2418 3DMarks
6616 CPU 3DMarks
Interesting result.. Faster than a voodoo3 3000, but the cpu is slower??

Final reality:
3.63 Reality marks
Again faster than a voodoo3 3000??

3DMark 2000:
1133 3DMarks
This time the voodoo 3 3000 is faster. This might have something to do with the newer 3dmark utilizing multitexturing. This is a weak point of the banshee.

Next testresults with a tnt2 32MB:

3DMark99:
2992 3DMarks
6811 CPU 3DMarks

Final reality:
4.00 Reality marks

3DMark 2000:
1386 3DMarks

This card is a lot faster than the voodoo3 3000. It also has double the video memory. Looks like ali loves the tnt2 more than the voodoo.. Will try other drivers for the voodoo3.

-AMD K6-2 @ 550MHz

Do you have an AFX or AGR version of this cpu with stock 550Mhz?

Or it is overclocked?
If yes, which voltage?

The processor model is k6-2 550AGR, 2.3v and is not overclocked. Default voltages are set on the mobo.
