Radeon 7500 blues

[Fauji]

Using a Duron 933 (133 MHz bus) with a radeon 7500 I get a fill rate of just 250 Mpixel/s and 600 MTexel/s while other people report twice as much. Is my 7500 crippled in some way being OEM? Powerstrip reports core/mem as 200/180 (DDR) and I can over-clock to 230/230 (which is retail speed) but that makes no difference to the fill rates!!

Even serious sam (using benchmark() )shows fill rates that are pretty low i.e. lower than MX400!

First off retail speed is 270/230, so you are far below that. You need to make sure you have the latest version of PowerStrip, because something is not right with the whole picture there. Who makes the OEM card you have? Because others need to stay away from it.

Oh, and welcome to the AT Forums.

Also, I have an OEM made by Ati, and it was clocked at 270/230 but reaches 315/280 (and could go higher) no problem.

I am sorry, I should have said I did manage to clock it to 280/230. The default was 230/180 (it has 5.5 ns DDR memory onboard). Thats how far it will go with stock cooling. Its an OEM (powered by ATI) that I bougt from newegg for $110. I agree the whole thing sounds strange. I will re-install win ME again with fresh drivers on a new harddisk for testing tonite. I am using the latest version of powerstrip. But I did install rage3d tool for overclocking and my PC kept locking up after that. I had to re-install my drivers after that.

I just cant understand how my fill rate could be half of what others get! I guess the fill rate is related to the core speed and what kind of pixel pipeline and number of texture units it has. I hope ATI have not got a cut down core in the OEM 7500!

The 7500 has the best 2-d that I have seen and I would hate to return it and get a Ti200.

I havent heard much positive output on the batch of 7500 OEMs comming out of newegg, 5.5ns is pretty low. Im really surprised ATI would even bring RAM that slow into the factory let alone sell them. Makes you wonder what kind of ATI card you would get in a prebuilt box?

Personally I'd return it and get one of ATi's own OEM Radeon 7500's so you can be assured it will be clocked at 270/230, which is what the vast majority of third party R7500's clock in at, and all of ATi's own OEM 7500's.

So, I'm looking at the 4 or 5 different "ATI Radeon 7500"s at Newegg and all I see is different parts of the marketing blurbs quoted in each description - certainly nothing that states RAM speeds, or Mhz speeds, or whether it is made by ATI or not.

Do I have to buy one of each of the "ATI Radeon 7500"s at Newegg and then return all but one? :disgust:

 

[Killrose]

HepDude, your best bet is to go with a 'Made by Ati" not a "Powered by Ati" Radeon 7500. Of course you could contact Neweggs customer service and tell them what your after.

Buy a card made buy ATi, not a third party Radeon 7500. Then your guaranteed that it will ship at 270/230 for the OEM model.
So far as I'm aware all currently available third part Radeon7500's are also 270/230 besides the one model which Newegg sells... and you bought

Sounds like you picked up the Radeon 7500 VE (Value Edition). Which side of the board are the RAM chips on, top (GPU side) or bottom?

 

[Fauji]

Both sides! 4 RAM chips on one side, 4 on the other. Its a board which says on the fan "powered by ATI". It should have said "underpowered by ATI". The RAM is definitely 5.5 ns DDR. I returned it and am now thinking of ATI 8500 (OEM again?) or Geforce 3 ti200. Thanks to everyone who replied on Anandtech forums. You guys are a great bunch.

Is that the leetle one with no DVI but instead has RCA composite along with S-Video and VGA?

I am wondering if that one is any good and still has dual monitor support (TV and VGA) to display videos to TV simultaneous to desktop on VGA.

 

[Fauji]

No its the big one with S-video, DVi and vga outputs. The specs are 230/180. It will overclock to 280/240. But my main concern is why my fill rate with this card with 3dmark2001 is just 600 Mtexel/sec (multi-texture) when everyone else reports double that! That could only happen if the core is somehow not 2 pixel /pipeline with 3 texture units. It still does not make sense. Either way I have returned it and I will decide on a GeForce 3 Ti 200 or ATI 8500.
