~ 4890 Roundup ~

It does indeed.

Also it would have been nice if they could have maxed out the GTX 275 clock and benched it along side to see how they both compare when overclocked to their maximums.
 
Could have been an idea but then they got extra core and memory speeds from all 4 off the ati cards with 3 of them doing over 1ghz and a ton on the memory. Think it would have been too much of a hassle to run through all the games again or did you mean just in 3dmark06. Think they should have used vantage for that personally.

Would be a good article though as a follow up to test all the cards maxed out on core and memory in all the games again. Thing i would be wanting to see also as how much of a gap the gtx285 could gain.

I'd have liked to have seen that as well...

The 275 *** I think is clocked at 713Mhz or somewhere around there - which doesn't give it a huge amount of headroom - I think they max out around 740 - which wouldn't have boosted scores hugely - but who knows.

I'd have been more interested personally to see how an OC'd to the max 260 maxcore stacked up :D

Yeah but they used software voltage increases on the 4890s so they could have done the same to the 275.
 
ah I missed that point :D

Well in that case, whip the cooler off, get it on some high end water or LN2 and you can pretty much max out the slider on a 275 without barely having to touch the voltage :P

Yeah. I think most review sites seem to miss the idea of cheaper cards being overclocked enough to beat/equal more expensive cards. I'd quite like a *good* (e.g. not Tom's Hardware) chart comparing stock and decently overclocked cards from various price ranges from about £50 to £400...would be very interesting...

edit: on air cooling, from a completely selfish point of view :p
 
I really wish I had access to a lot of cards as I would be happy to do some proper testing with all cards overclocked to their stable maximums on stock cooling.

Never knew it was so easy to up the voltages on the gtx series as no one seems to do it much. I am not sure it may have been greebo that said going past around 720 core matters little if you can't get the shader speed to go much further but i am not to clued up on overclocking with nvidia cards. Think what was said is shader speed matters more for performance than core speed when you get to around the 720 core mark on the gtx280.

Shader clock tends to get you the biggest gains in benchmarks with todays titles - once you've maxed out the shader clock unlinking the core and increasing it only gives very marginal gains.

From my experience - tho this was with earlier 260 and 280 cards - they respond better to increased cooling rather than higher voltages if your going for insane clocks.

I found that to be the case. You turn the volts up and the shaders clocks seem to suffer from the heat.
I used a 240 volt monster swiftech fan, and it helped a little, but without going OTT on the cooling, I found that extra voltage would actully make things worse.

The 285 has fixed voltage, but can you soft mod the 275 ?

Hey gurusan,

thanks for link, gonna read it now! :)

I was gonna say you have had pretty much every single GPU under the sun and you game at beyond Full-HD resolution so you have had a wealth of experience. I noticed you mainly gravitate towards ATI products which I suspect is due to their peformance vs price but you did try some of the newer nVidia stuff although I noticed you didn't stay green very long! :p

How are you finding the new HD4890? Did you volt-mod it or do you have one of these cards that feature software voltage adjustment?

I wonder if its possible to tell the difference between a 1GB HD4850 and a 1GB HD4890 outside of benchies? :cool:
