[Denny] ATi HD2900XT 9.5" 1GB GDDR4 testing 56k warning

[MAS]

512Mb for 2900XT was not enough - so it has bad results in heavy videomodes

1Gb of memory will give a great boost

[DStealth]

i forget to change to 7.5... i will try it maybe tomorrow or next week


here is some 16x+4x weak CF testing, 1st card @ stock clocking and 2nd card @ 500/500 clocking (much lower than stock clock speed)


3Dmark03.......................60120
3Dmark05.......................26586
3Dmark06.......................19390


just like Kinc said, CF uses less CPU overhead
also 01 doesn;t really benefit when CF enable

according to coolaler
3D06 701/1163 SLi.............19819

3D03 685/1150 SLi.............69224

Right 2 cards and less CPU usage with CF.
But let we talk freely, when will this card hit retail ?
1-2 mounts when g80 will be 1 year old architecture and will be cheaper for sure. Now we have ~500$ for GTX and due to less heat overclocked can beat 2900XT 1gb GDDR4 even in 3dmarks comparing your scores. All ATI drivers right now are on open beta state, so in games there is no need to compare them even
I think last year ATI made lots of disappointments and this card, would be the continuation of the saga

nice scoores

[Cornelious0_0]

Very nice scores...I really need an HD2900XT...my board is begging for some real VGA power!

Hi Denny why did you clock that second Card only to 500/500 ?

Some further question your a girl or a guy denny ?

It's what i think too, specially cause the ring controller (512/1024bit in 2 ways) is designed for 1024Mo GDDR4.. this should be enough for stop the big lost of FPS with AA @ High res.. ( but i think the problem come too of a better optimisation for the AA, 7.5 have begin solve this prob on some games..)


Nice bench Denny, and i like the perfect quality of the pics you have put on the thread..

afaik its a core (r600) problem. no amount of memory bandwidth or size will help that. the current big losses aren't due to memory bandwidth as the current 2900XT has enough memory bandwidth so deal with any AA the GPU can delve out.

as far as ATI's own engineers have said the GPU is built around CSAA which should be used more in future games.

will this give the 8800gtx a run for it's money?

unless the retail version is clocked higher i doubt it (at 4/8xAA).

[CraptacularOne]

Nice scores Denny Keep them coming.

[bloodbanger]

any info on price-range for these puppies??

[BuBBle.D]

Probably a 100 bucks plus for this card.

[bloodbanger]

so probably still cheaper than a 8800Gtx?So still not a 8800GTX killer than,lol....

i use p975 4.4G yesterday which is 8x+8x, the only score increase is CPU score XD
and then i back to P965 4.4Gtodat which is 16x+4x... same score...
makes me believe CF doesn't make a lot of different on 16x + 4x or 8x + 8x

[ahmad]

You got two bridges, thats not suprising. But it is good news for the rest of us.

I see a big diference especially in SM3.0 in 06. In 05 there aint much difference.

my 05 score actually drop using P975
with no overclock @4.4G 3Dmark06 P965 and P975 both give me ~20400
and atomworks can't detect 3D clock.... sad

[trajik78]

good article on the effects of different slot combinations:

http://www.tomshardware.com/2007/03/...ling_analysis/

seems the biggest loss is when using 4x. the article also shows that it really does pay to have a board with 2 16x slots, but only REALLY matters when running this latest generation of cards.

How about Company Of Heroes DX10 ?

@P35 Asus P5K-D motherboard, Intel Quadcord 4.5G, GSKILL 2GBHZ 1023 CL4
16x+4x, PCIE 120

3Dmark05 close to 29k



3Dmark06............... SM2 8218 and SM3 9053


================================================== ===========================


@P975 Asus P5WDH motherboard, Intel Quadcord, GSKILL 2GBHZ 1015 CL4
8x+8x PCIE 138



4G
3Dmark06............... 20056
it is my 1st time see GPU no mod overclock and stock cooler with 20k+ on 06



4.4G
3Dmark06




but even with ~4.5G

3Dmark05............... 28230
game1 and game 2 much lower than P35
but game 3 is up to 193 FPS, 5 extra FPS increase shows GPU power is much higher than P35 GPU power

I'm fed up with 3dmark scores. 2900XT 1GB can only fight 8800 Ultra with 3dmark not games.

not important to me cuz i don't play game

[Fr3ak]

Denny, are you sure that the P5K-D uses 16x and 8x? Isnt it 16x and 4x?

With better cooling and overclock of both cards, K|ngp|n's record of 24.4k seems to be within reach...

[AbelJemka]

I'm fed up with 3dmark scores. 2900XT 1GB can only fight 8800 Ultra with 3dmark not games.

Cost 2 times less than 8800 Ultra.
