I'm currently upgrading my VLB system. It is based on the Aquarius MB-4DUV motherboard, currently runs a Cyrix 5x86-100, has 32MB 60ns RAM and a Paradise 4030 cache controller.

Few days ago I got a nice Cirrus Logic GD5428 VLB in the mailbox, it had 1MB and I upgraded to 2MB. This works fine and provides some bonus colours and resolution over the old GD5424.

This afternoon I managed to repair an Advance Logic ALG2228 VLB 1MB which had broken traces (actually fixed a bad earlier repair attempt by three previous owner). After testing it seems to be a little faster (~5-10%) than the 5428 in DOS benchmarks. The downside is, there are no sockets for ram upgrade, so no 16b colours at 1024 resolution. I can live with that.

Now I know the Cirrus had pretty good compatibility with everything, but for the ALG it's just guessing to me.

They both are not the fastest cards in VLB kingdom but they are all I have. Actually I don't need to have the fastest cards in the world.
I've got a K6-3+ with voodoo3, also good and fast DOS support.
I've got a 386 DX 40 with ISA GD542x too.
So instead on pure speed I think I need best general support.

So how would the ALG do, compared to the GD5428?

2301 is mostly fine (for what 486 can handle anyway) - https://gona.mactar.hu/DOS_TESTS

I’d pick the Cirrus Logic with 2MB. You won’t notice the small performance difference but you might appreciate the extra VRAM more and the CL has unbeatable compatibility.

For whatever it's worth the Cirrus 542x were super common in 486 machines. Just thinking back to the second hand systems I had back in the 1990s I know I remember seeing a 5429, 5428, and 5426. So you can almost guarantee any 486 game was at least tested with one of those. Your post is the first I've ever heard of the ALG2228.

I have not tested these exact chipsets in VLB, but I have tested very similar ones in PCI. The Avance Logic ALG2301.B PCI is roughly 3-6% faster than the CL-GD5430 PCI. Some specific numbers, tested on a Pentium 75 -
Doom:
ALG2301.B = 34.6 fps
GD5430 = 32.6 fps

Quake 320x200:
ALG2301.B = 18.5 fps
GD5430 = 17.9 fps

3DBench 1.0C:
ALG2301.B = 61.1 fps
GD5430 = 57.6 fps

The more I learn, the more I realize how much I don't know.

Anyone got working Windows 95 Drivers ? (using Windows 95C)

i have V7 VEGA Plus VL with BIOS 2.0 and did not manage do get any Driver working..
I Already tried a few from fi ftp mirror and other sources.

The ALG does very well in DOS.

Thanks for the advise and benchmarks. These benchmarks do confirm my own:
Testing with a DX2-66, 8MB ram, 265kB cache. (Yes different system, but benchmarks tend to scale well between these)

Pc bench 1.0c:
ALG: 43.3, 5428: 42.1, tgui9420: 38.8

Chris'3D VGA:
ALG: 30.7, 5428: 27.3, tgui9420: 25.5

The differences are small enough not to notice them. The very common gd542x cards just do what they're supposed to do, that's true.
I guess it would be the safer choice, and I'll put the 2228 aside for now.

Thanks all!
