Eisa video card performance.

Postby Baoran » 2018-12-01 @ 10:12

I have one of those eisa 486 motherboards. Anyone knows if there is any performance gain if you replace normal tseng et4000ax isa card with an compaq eisa card like this https://www.ebay.com/itm/Compaq-EISA-VG ... 3500140287

Running benchmarks shows small differences yes, though how noticeable may depend on other system factors like CPU... I have only ran these tests on a 386. A 486 may give greater gain, more noticeable difference though I doubt not by too much.

I have around eight EISA graphics cards and benched them together if it is of interest: -

The Compaq cards ran really well in DOS and were great for Doom I recall.

Thanks. I didn't even know that eisa were used with 386. I always thought they were a 486 thing like vlb.

I own a Compaq 486 33Mhz System with EISA, it runs Doom like Hell.
I can make Benchmarks for comparision.

EISA has more bandwith, you will get roughly 20mb/s in real world.

I am curious too. I have a 486 33mhz too and would like to know how many realtics you get with the eisa card at full screen benchmark.
