Crysis
Crysis is a game that can beat down all cards. We're once again using the high settings with the shaders at very high, and even at a fairly tame resolution of 1680x1050 only 8 cards manage to get past the magical 30fps rate, with nearly half of those are just squeaking by. Crysis is particularly punishing on the HD3000 series cards at these kinds of settings, where only the HD3870 X2 was competitive without resorting toCrossfire. This makes the placement of the HD4000 series all the more important.
What we see with the 4870 is very promising. Here it leapfrogs the $100 more expensive GTX 260 and delivers 7% more performance at the same time, delivering manageable framerates. It does struggle a bit to separate itself from its cheaper brother the 4850 however, with only a 20% boost in performance for a 50% boost in price. This isn't unexpected of course, it's almost exactly in line with the shader power difference between the two and we've known that this test is shader-bound for some time, but we're not seeing the memory bandwidth make even a slight difference here even at the more unplayable 1900x1200 resolution.
Neither HD4000 card can crack 30fps at higher resolutions however, after 1680x1050 you either need to turn the settings down or start throwing down additional cash for one of NVIDIA's more expensive cards or a Crossfire/SLI solution. In either case, this situation highlights the fact that on a dollar-for-dollar basis, the HD4000 series has negated NVIDIA's commanding lead with Crysis merely two weeks ago.

Apple has passed over control of Open CL to the Khronos group, which manage open sourced coding.To all intentions and purposes, it is open source. :-)

i hope you do 3x crossfire can do. maybe a 4x 4850 vs 3x GTX 260 just to satisfy us readers for the moment would be lovely!DerekWilson - Wednesday, June 25, 2008 - link
i'm not sure if this is supported out of the box ... ill have to check it out ...emergancyexit - Wednesday, June 25, 2008 - link
i would really like to know what type of performance theese cards could get in an MMO. (and hopefully compare them to some cheaper cards) Games im interested in are some of the newer titles like Age of conan ( i hear it's graphics are great and is a workout for even a 8800 ultra) And Eve-online (thier new graphics engine works cards pretty hard too)MMO's Graphics usually get pretty intesive with some odd 200+ characters flying around shooting fireballs evrywhere with missles sailing through the air in a land of hundreds of monsters as far as the eye can see. it can get pretty demanding on a gameing computer, just as much (if not more) as a hit new title.
for example, on my current Rig i can get around 50FPS steady at 1440x900 but on Eve-Online i get 35 at the most at peacefull times and 20 or even 15 in a large fight with FEW graphics options selected.

Great review, the 4870 looks to be fantastic value. However, we're missing the 'heat and noise' part.skiboysteve - Wednesday, June 25, 2008 - link
Not only do these cards rock, but I wouldn't be surprised if AMD has an ace up its sleeve with the 4870x2... with that crossfire interconnect directly connected to the data hub that you showed on the chart. That and the fact that they have been looking forward to this crossfire strategy of attacking the high end for quite some time so they might have some tricky driver stuff coming with it.I have been disappointed with the heat and power consumption of these cards. But:
1) Someone said powerplay is getting a driver tweak and, I can always clock them lower in 2D than 500/1000 (which is insane for 2d)
2) That hardware site someone linked earlier showed a more than 50% reduction in temperatures with an aftermarket cooler! Thats insane!!
And finally, if I can get the 1 & 2 fixed... I want to know how well these babys overclock. If I can get a 4850 running like a 4870 or better... yum. And in that case, how high will a 4870 OC? And I want to know this with a non stock cooler, because apparently the stock ones suck. With a non stock cooler if the 4850 clocks up to 4870 level, but the 4870 clocks way up too... i'm gonna have to grab a 4870.
So yeah, fix #1 and #2 and find me non-stock cooler OC #s and I'll go buy one (maybe two?) when nehalem comes out

Impressive review, Thanks :)A few glitches:
It says "Power Consumption, Heat and Noise", but the graphs only shows Power Consuption.
In Page 17 (The Witcher), in second paragraph, it says 390X2 instead of 3870.
Thanks again.
Cheers from Argentina.

atleast that was the tile of the second to last page...but only see two power consumption graphs?Proteusza - Wednesday, June 25, 2008 - link
I quote one Kristopher Kubricki regarding whether the RV770 is inferior to the GT200:"It is. Even AMD isn't going to tell you otherwise. You can debate this all you want, but it's still a $200 video card."
So, please tell me now why I should pay $650 for a GTX280. I'm struggling to see the logic here.

I can live with a greedier card than my 8800GT but I refuse to put up with a noisy machine.Any comments on the heat and noise please? would be nice!
