Official HD 2900 Discussion Thread

[ahmad]

That's the sort of thing you'll find on that blog. Can we not ban the posting of these piece of crap fanboy blogs?

First of all, those are official benchmarks released by ATI. Not that they are worth anything to me or you.

Second of all, they used 8xAA/16xAF and adaptive AA. ATI's 8x AA implementation is different from nvidias, so Nvidia cards take a larger hit from that alone. ATI always had more efficient AA algorithms, so its no surprise its wins in most benchmarks.

Third point is, its compared to the 8800GTS. 8800GTS is not the 8800GTX so no great achievement there from ATI.

But like Kinc said, too many variables for us to take anyone's word for anything...

R600 has 16 TMU's while G80 has 32

That is why it stays behind

Here is the one of the key reasons why R600 marchitecture falls behind the G80 GTX version. While Geforce 8800 GTX or G80GTX has 32 Texture Memory Units (TMUs) Radeon HD 2900 XT has 16 only.


TMUs are responsible for getting the textures in your games and more you have the faster you can handle the texture work.

Still, the Radeon HD 2900 XT at 750 MHz core is about 30 percent faster in raw clock speed from Geforce 8800 GTX at 575 MHz and finishes the texture cycle some 30 percent faster then Nvidia.

In spite of that this is not really a fortunate solution as Nvidia has twice as much texture memory units. The only hope is that ATI has more effective TMUs, but this is one big marchitectural disadvantage over the G80 marchitecture.

So fuad gives us hope that this still maybe a g80 killer.....

One more thing, according to beyond3d, the latest release-candidate driver from ATI causes the r600 to do weird and wonderful things like destroy an 8800gtx in performance...

Time to get some sleep now.

[generics_user]

this is the best hype i've ever seen, so many benchmark scores and ll completely different (one showing a slow card not keeping up with the gts, the other one a tie between GTX and XT and the third a huge lead for ati)

everyone seems to talk about their product, some bashing and some praying but no one rlly nows, this is better than cinema



BTW: pcgameshardware (germany) got no info about a launch on may 2nd, maybe they're releasing final drivers for testing on this date, NDA still seems to be lifted on 14th:

Nice info!! Bit weird that the R600 only has 16 more physical unified pipelines....

the 8800gtx scores were done in 3dmark05, x2900xt scores in 3dmark06.
of course it's higher!

Yeah and 3dmark 05 was probably at a lower resolution too.

[Gorgul]

Only 60-80% faster in mosts games than the old 1950XTX.

[96redformula]

Maybe this will make for some killer price drops after all . I am all for killer price drops despite whoever has the crown.

On a Side note: I HATE BENCHMARK GRAPHS THAT DO NOT START AT 0 !!

Edited note: Those last graphs are for special circumstances only ! Notice they are with HDR and the second one is for stencil shadow, whatever that may be.

Sooo what, you play games at 640x480x16bit color?

[S1mon-]

I can't wait to see some real benchmarks!!

[96redformula]

I don't understand you.......

Inside joke or something about what I said? I meant how they started the graph with 80% making it seems further stretched out of a difference and also how it is using % and not actual FPS.

My 8800GTS maxes out my westinghouse 27" actually at 1365x768 in all games so far.

[XeRo]

Is that the lowest res? I think I play my games at a res lower than that.

my point is that Those last graphs are not for special circumstances only, simply because HDR and high detail resolution is going to become massively more popular

What part of "60-80%" warranted an "Only" in the beginning of the sentence ?

If ppl keep that attitude up, there will be a lot of jaws dropping on launch day...

[situman]

Hector Ruiz wouldn't allow a catastrophe of that magnitude...

There are so many examples, recent ones too to dispute that, but that's an entirely different discussion.

keep in mind the 1950xtx is the current flagship, and the 2900xt is only the next-gen 2nd card, and thats why its just barely faster. 1950xtx should be crushed by the 2900xtx.

Soo you don't think 40+% performance improvement isn't crushing?
You might want to tell that to the Conroe fanboys

Its much more than 80%. In some of those numbers its close to 100% faster.

Saying only 60-100%.. is silly. Thats a huge difference.

We learned that AIB partners for both NVIDIA and ATi have already received the GeForce 8800 Ultra cards and Radeon HD 2900 XT cards and are preparing for shipments now. These cards will hit the retail shelves by May 14th, the same day AMD officially launch their R6xx series. However, only 2900 XT cards will be available while 2900 XTX, 2600 and 2400 cards will be available at a later date. We heard that there are some 6000 pieces of 2900 XT cards by the first week of launch and no supply problems are expected.

[perkam]

HD 2900XTs at $399 should be enough to hold off the G80 series for now...

A $700+ Ultra isn't going to make a dent in AMD's R600 sales, irrespective of how good looking it can be

It is crushing by any means.

The numbers for example in 3Dmark06 with the HD 2900XT are double than my current card a x1950xtx.
Thats crushing.

It runs Vista and Crysis generation 2 engine in DX10 and 10.1 which no other ATI card can do previous generation, that is crushing.

It has HDMI, programable GPU and will become more and more performance wise in older games and newer games so the crushing will continue over time.

It draws more power than any other previous generation and crushes by power alone

Its a canadian card that is crushing alone even it it does not count.

It has high quality at default and will run anything I can throw at it and will come cheaper by 2k at launch which is welcome since the older cards did cost to much in high end.

It has coustomable AA with a better imagequality than Nvidias 8800 and the old x1950 series.
So not only will it crush the old tech but it will look better doing so

It runs at a higher precision point than x1950xtx.

It will crush due to having more transistors.
700mil+
It has a wide memory bandwidth and its a lot more than previous gen.40+gb more.
Rejoice all 24 and 30inch screeenowners.

It process HDR textures biliniar filtered at "7X" faster from previous X1 gen.

Its HOT and RED and has looks you can die for.

What else do anyone want?
Green and slimy or RED and HOT?
Are Paris Hilton not enough in daylight?

Anyone not seeing the numbers and the performance and the tweakability are fooling themselves, this card will last a long time, much longer than Nvidias serie.
A lot of people still use 9700 series from ati.

Crossfire scales much better than previous generation which then 2 cards are something even I might consider down the line for once.

The card also overclock well and 1ghz core might be mainstream with watercooling...that is so sexy and hot by itself.

It crush the previous generation due to some good old fashion creative thinking from ATI design team.

HD 2900XT
Red and hot and with looks you can die for, what else would a man want?
If ATI would deliver the cards with one hot sexy woman and do personal service but I consider that over the top though....
