Powercolor HD4850 512Mb (single & Crossfire)

[Stuen4y]

i only instaled the cards ~ 3 hours ago (lunch time in midle)

regards

OK then, I see you want to install the second card, so to unleash the beast. We'll wait till you get satisfied with the CF and then will ask you for some other possible bench games - like F.E.A.R, UT3, World in Conflict, GRID, Age of Conan and the promised 3.2 ghz processor tests, of course if that is no problem . GL with the CF .

Any micro-stuttering issues you could have noticed while benching, mascaras?

[WrigleyVillain]

Ooops. Sorry !

I just corrected that

Heh, no problem. Figured you had to have seen that so was confused. Anyway, fyi, jimmyz's second 4850 shows up today so there will be xfire results in that thread soon as well

Now only if one could overclock them already.

added crysis "in game" crossfire

no micro-stutering at all in 1st level , but dont get too excited because with HD3000 series crossfire on crysis 1st level also no micro-stutering , but other levels yes !


i will test more levels and also very High

Hi!!!! thx you very much

Can you Oc memory and see how it scales??? so we can see how much bottleneck is because of ddr3? Thx you

[STaRGaZeR]

Mascaras please include some detailed comparisons of AA perfomance hit in other games

[zerazax]

Looks like the shader count on the RV770 is really starting to kick in... just noticed that DX10 high @ 1280 x 1024 has 34.41 avg FPS for the 4850 w/ 4xAA while 9800GTX is 34.64 w/ no AA... interesting!

[mascaras]

nice pic

1600x1200
very high

sweet thread!

can't wait to see more benchmark results. The 4850 seems to be right on the 9800GTX's ass,. Good to see!

all testes till now

Wow... 4850 is realy close. But nvidia is going to launch drivers that'll boost 9800 GTX performance (if Fudzilla isn't lying). I wonder how much will that driver change the situation.

But you still have to consider this. These are early drivers for the 4850 and the performance of the drivers will get better.

Yeah, I understand. This makes it even more interesting...

[mascaras]

added crysis in game (high & very high @ crossfire)


In last level of Crysis @ crossfire i noticed few breaks/stutering (example : when runing down the stairs inside the ship ) !

[godsfist]

So do we know the performance increase of the 4870 over the 4850 yet?

ok extremely good to know. and by the way fantastic review!!! i love the screen shots of in game FPS. thanks for giving us that info on the mircostuddering. great review as always man!!

[MrHydes]

lovely review Mascaras as always, my favourite of course...

how 4850 performs in what concerns to image quality, is smoth or what?

any breaks in Single or CF config?

cheers might

[mascaras]

image quality so far is good !

will test few more games !


regards

[Luka_Aveiro]

Well...

1280x1024 4xAA 4050mhz e8400, 2gb Vistax64 64 bit test 8800GT @ 625/1000

Drivers @ default values



I am the only one that thinks this is not surprising? I mean, 8 months after 8800GT is out, and for more 45€ you get about the same performance (at least at those settings)

[Dragy2k]

nice review....just cant wait till we get some modest OC results, when that nut is cracked im sure this card for the price will rock.....bring on the big boys toys !!

[WrigleyVillain]

So do we know the performance increase of the 4870 over the 4850 yet?

No we don't. Higher clock speeds and GDDR5, new ram rumored to provide 5-10% boost in certain scenarios.

UPDATE: hardware.fr 4850 review posted in Xtreme News

Performance greater than 9800GTX and 8800 Ultra. Bring on the 4870!

[BigDisk]

Hey mascaras,

can you try some different frame buffer depth and see if it has any impact on micro-stuttering??

Thanks a bunch !!

[metro.cl]

Just a Tip, include min FPS too that is important great review you got here waitting for more tests

[mascaras]

grid Race added


best optimized game for Crossfire i ever played


Btw:

9800GX2 results i had saved with same system but Grid Demo (not full game like HD4850 CF) and only 1680x1050 (HD4850CF in 1st post @ 19200x1200)







regards

[Blacklash]

No WiC results?

[xMrBunglex]

great thread. i heard GRID didn't scale well with CrossFire. did you rename the .exe or force AFR through CCC? or did it just scale well out of the box?
