I thought the ISA chips stopped around the 5428/5429? Wikipedia lists the 5434 as having a 64bit memory interface - it would seem a bit pointless having such a fast design on the ISA bus 😀

I know that 5434 cards were made for the ISA bus too, never owned one though... would be interesting to see some speed benchmarks, hope someone here has such a card and willing to share the fun 😁

I know at least one person in here has one. It's an Orchid card of some sort.

Orchid Kelvin 64-ISA VGA card, quick test

I am sure retro games 100 will benchmark this 😀

I'd really like to, and I would do this immediately, but very unfortunately I'm not at the same location where all of my retro equipment is. Ugh! I'm very sorry for this inconvenience! 😢

I use a diamond speedstar64 in my 386DX40 machine, I did a few dos tests that may or may not prove anything in a machine such as mine however.

ET4000AX CL5434
PCPBench 4.0fps 4.0fps
3DBench 15.3fps 15.3fps
Doom 7.0fps 7.1fps
Quake 1.8fps 1.8fps

I tried comparing speedsys results but it would'nt do the test with the ET400AX, just says VESA UNKOWN.

10mhz 8mhz
5434 3,295 4,123

Okay just tried the 5434 in a POD83

Speedsys

PCLK/4 - 3,777
PCLK/3 - 6,099

3dbench

5434 50.0fps
ET4000AX 50.0fps

PCPBENCH (VGAMODE,) ET4000 wont do it svga for some reason

ET4000AX - 16.3fps
5434 -16.3pfs

I daresay their is no discernable differance in any benchmark for dos, The 5434 wipes the floor in windows 95 as it has those accleration features, IMO the 5434 is the best ISA video card, perhaps an ati accelerator would be its equal

You could try running univbe before you run speedsys to get ET4000AX results.

Its not isa... but I sold a 2mb VLB 5434 on ebay a lit ago.

speaking of ebay, here is one for sale http://www.ebay.com.au/itm/Diamond-23020039-2 … #ht_7963wt_1042

Geez...that 5434 VLB card is damn ugly....and the speedsys results are terrible.

What should(could/is) a VLB video card score in speedsys?

I would think you should be getting twice the score you had posted. Are you certain your memory upgrade is working?

I'll have to run speedsys on my CL 5429 for comparison. CL 5434 should be faster than 5429 as far as I know.

Ive got a VLB 5429 2mb, gets 8,200kb/s in speedsys.

my isa 5434 came with 2mb out of the box, it certainly works with the extra memory, im pretty sure you need to be running windows programmes to show the benefit of 64bit/2mb with this card,

In windows the main advantage is that you get accelerated graphics, but that only really helps for drawing window elements.

The card runs in 64-bit memory mode (with 2mb installed) regardless of whether or not you are in DOS or windows, and the performance gain should be quite noticeable. Most ISA, VLB and early PCI cards work like this if they are 64-bit or 32-bit interleaved.

I'm going to try out my CL card today and let you know the results. Maybe the VL bus is just not very good on your motherboard. Is it one of those VL/PCI type boards? The reason I am concerned is that my trident 9440 scored higher, and trident is supposed to be the slowest thing out there. I have an ISA card that isn't much slower than your CL cards.

Okay. I got the CL5429 going somehow. The speedsys results are unimpressive. 8.3MB/sec. I always thought cirrus logic was supposed to be a speed champion in DOS, but maybe not. At least according to speedsys, the Trident 9440 is faster.

I strongly recommend you switch to vidspeed for your comparison. Speedsys seems to be ok to see any difference if you change clockrates, but not if you change cards.

Anybody in here with this card? I have heard it is supposed to be the fastest ISA VGA card for DOS, but I have never seen any data to back it up. I currently have an ET4000W32i based ISA VGA card, and while I was not impressed with the vidspeed results, the speedsys results are VERY impressive:

5.3MB/sec at 8MHz
6.6MB/sec at 10MHz

For comparison, most of my ATi ISA cards get about 2MB/sec (trident 1MB/sec)

Please post CL5434 ISA speedsys results and state the speed of the ISA bus.

Abit FU340
Cyrix 486DLC-40
16 MB RAM / 128 KB L2 cache
ISA BUS = 10 MHz

SPEEDSYS:

Trident8900: 1200 KB/s
CL5434: 3227 KB/s
Mach64: 3574 KB/s
ET4000 W32I: 5296 KB/s

3DBENCH:

Trident8900: 18.8
CL5434: 20.4
Mach64: 20.8
ET4000 W32I: 22.8

Tseng seems to be the King of the ISA graphics bus.

I just did a speedsys test with my STB 1mb 5429 isa card...
with wait states enabled I get 4281 kb/s
with wait states disables I get 9313 kb/s (is this real???)

I am using an IBM PS1/pro that was a 386sx/20 and now has a 486slc2/40 clip-on cpu upgrade...
