Hi guys,

Just wondering if there are any 2900 1GB GDDR3 vs 2900 1GB GDDR4 reviews or forum threads out there?

Mainly wondering as have seen around some 2900pro 1gb gddr3 and wandered if they are worth it COMPARED TO the 1gb gddr4 cards? (assume same clock speeds, either pro or xt).

the memory's not really worth it. in general the extra memory only helps if you , well, go over the 512mb limit, which is rare. ati have had a lead for a long time on nvidia in terms of texture compression. lots of benchmarks on the 640/320gts reviews would should this drop in performance in situations where the 640 suddenly got double the fps of the 320gts. but in these benchies the 256mb 1950xt went ahead of the 320gts because lack of memory for textures simple destroys performance. ati's way better compression meant that what didn't fit in the 320mb memory fit into the 256mb memory. in other words 512mb seems to be plenty for ati right now and for some time to come. also worth bearing in mind is the 2900xt 512 used 30W more than the 2900xt 1gb gddr4, because ddr3 is sucking in a lot of juice at high speeds. so the 1gb version or anything with gddr3 is going to mean excessive power usage for little benefit. the reason the 2900xt gddr4 does better is , well lower power consumption, gddr4 is overclocking quite a bit further. the 512mb 2900 pro is a steal of a card though.
 
That's what I'm thinking you see, will it really be worse for overclocking? I would think that with tighter timings the gddr3 would actually be performing better than gddr4? I could easily out perform a gddr4 1950xtx with my xt on only gddr3 and excessively clock the memory. Was thinking that maybe the 1gb 2900pro may be the same?

Power problems aside I mean...

Just read reviews of the 512mb pro, the extra 512mb dont make a diff, unless your playing at insane uber res on a 30+ incher, where you might get about 1 frame more. :p

Only card worth getting is the GT, obliterates the pro, and same price.

no, it doesn't, not even close. loadsamoney, you talk such entire trash. most of the reviews that are trickling out, that aren't part of the completely ridiculous release reviews are mostly showing that a LOT of games at 1680x1050/1920x1200 where the GTS does infact beat the GT, infact in a majority. the 2900pro is simply an underclocked XT, for £150. the 2900xt rarely loses to the gts by more than 5%, beats it by 30% in ut3 engined games(of which without ut3 being release, there are loads of ut3 engined games already should indicate just how used the engine will be like the previous engines). sorry but the pro is still a fantastic card, and for all 1680x1050 and up resolutions we should regularly see the 2900 pro/xt win over the GT when aa/af are used. in a bunch of games where the maximum and average is won by the GT over the 2900xt, the minimum framerate is HIGHER on the 2900xt. i DON'T CARE if the GT can do 300fps when its not stressed while ht 2900xt can only get 80, minimum framerate is most important, the GT is crippled at all the resolutions its designed for. JUST like the 320MB gts, its an insanely powerful core, as powerful/more powerful than the GTX completely and utterly crippled for use in any real resolution. its way to overpowered for 1280x1024, and completely crippled for everything above that, and in the next year it will struggle more and more with games that push the hardware further.
 
I wasn't asking about whether to get card A or card B, I was asking about the performance differences with gddr3 and gddr4 on the 2900 series. The reason I talked about the 1GB version is because there is not a 512mb gddr4 version on the xt. If there was i'd have used that as a comparison.

So... has anyone actually seen a review, tested it themselves, or has seen the differences on forums with these 2 memory types on the HD2900 series please?

drunkenmaster, the 8800GT is a better card than the old 8800GTS 640's with 96sp's, the 8800GT is faster, I know as I've had 2 8800GTS's and now an 8800GT.

And the 2900XT at 1680x1050 compared to an 8800GT and when including AA in there the 8800GT totally destroys the 2900XT.

And wth are you on about a GTS 320 having a better core than a GTX? honestly, are you drunk? you're telling everyone all the reviews are crap and coming out with some trash yourself, the 8800GTS 640 in my experience is faster than a 2900XT, the 8800GT also is, the 2900 cant handle anywere near as much AA as my GT can and also the GT is topping my 8800GTS too.
, my 8800GTS proberbly would only be better in crysis at 1680x1050 were I might be able to enable 2xAA.

look i have now 2900xt 1 gig ddr4 core:860 memory:1107 temperatures : 34 ~ 36 idle 40 on load and i can get even more i crashed when i tried core on 907 i think. im using water/liquid cooling of course heatsinks on ram.

i hope it helps :rolleyes:

helps what?
 
yeah your right, i talk complete trash, i got my cards mixed up, the GT is only GTX performance, not the faster 2900 pro/XT, my apologies.

Your also right about the GT being crippled with AA/AF, im playing just about everything on my GT with 16xAA/16xAF and the superior IQ of SuperSampling, and it absolutely rips through everything, so looks like an RMA is in order, clearly ive got a defective card, thanks for letting me know otherwise i wouldn't have known, i better get it RMA'd for a working one which cripples under AA/AF.
 
Everyone> This is not a 8800gt thread, please keep your comments for that confined to threads, ta.

Thanks for the info Psychas :) What equivalent speed for the gddr3 base mhz would you need with ddr to match your base mhz gddr4?
