I've been thinking about this since you posted your benchmarks. One thing to consider in VLB benchmarks in addition to whether the card uses VRAM vs DRAM is if the card has 1MB or 2MB of ram

None of these will be a big difference, maybe 3-5%, but when so many cards are clustered closely together in the charts, it can have a big impact on the ranking.

I think about the same.
Does the Tseng Labs ET4000/W32i use interleave at all on that 1 MB card or will it run faster with 2 MB?

From what I've read the interleaving is disabled when you have less than 2 MB.

when I looked at the chart I was surprised to see Cirrus Logic wasn't last on the benchmarks!
I stare at the eBay store screen at the prices for Cirrus Logic VLB!

I was also expecting slower results from Cirrus Logic.
In terms of DOS compatibility, Cirrus Logic cards are the best choice.
I have also selected a Cirrus Logic card for my 486 VLB DOS machine: an Alaris Tomahawk (CL-GD5428).
However, PCChips M919 owners must avoid Cirrus Logic cards.
Pentium VLB systems with OPTi and VIA chipsets also do not like CL-GD542x cards (the CL-GD5434 works perfectly).
But likely Pentium VLB builders going to select a faster card.
