Enjoy it while it lasts ATI.

Unless nV screws G300 up (rebranding G200) then it may be a nice time but wont last forever.

If only they could get a damn seperate shader clock. With 1600 SPs running at 1.7GHz they could blow nV out of the water....

It's dissapointing to hear the memory had to be put so low...
Though I'd love to liquid cool my i7, then add a 5870 and liquid cool that also. I got a radiator at work that can likely handle a 10 kilowatt system, add to that it's constantly cooled by sub zero temperatures (during winter atleast), with a 5 barrel resevoir, and dual 24" fans (used to cool 3000psi hydraulics).

Even more dissapointing to see it can't keep up with it's dual 4xxx series cousin.
Also, GPU waterblocks just look so inneficient...

WOOOOOOOW extremely low temperatures... but not worth the 500W draw.
I think now am interested in water cooled video cards.

but honestly, i thought the gain will be 20% at least... disappointing.

You made a mistake on the test and benchmark page on the Crysis Bench config. It states you tested it at low quality. This would mean at least 100-150FPS....

Nice work but I also wish you guys tested Crysis at Very High settings.... its always great to see Crysis tested at its maximum threshhold.

Being a single card 5870 performs very impressively...
And the power usage is impressive too(Only on stock).

This is the best card for now and with a lil price dip it'll be fav. of all high end gamers.

I love the draw on their oc 1 gpu is greater then 2 older gen gpus draw that's just hilariously bad results. Still with the waterblock set up maybe you can afford the 1000 dollar electric bill with you're fastest possible machine. Sorry but as far as ATI venders powercolor is low on the list of ones i trust. Poor 5870 gpu wasted on excess and ya can't waste those things, hard to come by with tsmc doing jack in the yields department.

I have convinced myself watercooling is a must for GPUs.

I am running a watercooling setup on my CPU alone at the moment. Despite majority of heat gone from internal case, my HD4850 card would barely escape overheat in room temperature of 23deg C in UK winter. I once tried moving my soundcard closer leaving 2 inch clearance from HD4850 and it crashes every single time when I run Mass Effect. Now it crashes once in a while and I am 100% sure it's due to overheating of the GPU. Load temperature reaches 106 deg C. The card crashes at 110 deg C.

so i`m 1 of the few people who was not surprised by the outcome!? 2 4890`s packs a decent punch, the fact 1 5780 can keep up with that is not bad, I did not expect anything different...

Keen to find out if DX 11 will make a difference once its mature...

I don't understand how the 5870 can be slower than a 4870x2/2x4890. Aren't the specs EXACTLY the same, except for the 5870's HIGHER clocks and that the 5870 has all those specs in ONE gpu die rather than two?

i've seen in many sites that 4890 in crossfirex scale eceptionally well.
4890 crossfire even beats gtx 295 (gtx 275 sli)! but a single 4890 is
equal or less in performance of gtx 275. its as though the card was made
for crossfirex.

A note on your setup issue: there isn't really any "input" or "output" nozzle. Your water will not change temperature very much before and after one single component (GPU/VRM/VRAM). Also, after it has made a few passes, the entire water system pretty much gets to one temperature and stays there (unless the load changes). The input and output is interchangeable between the two nozzles.

^ +1 to jonxor. With these blocks, it doesn't matter which is inlet or outlet...and once your temp reaches operating temps, they will only go up depending on load and your ability to dissipate heat via the rads and ambient temps.

This article is crap. Sapphire has already sold 4890 @ 1 GHz way before 5000 was even released. Why buys a card, overclocks it and calls it a breakthrough when plenty of factory overclocked cards has already done it?

And what's up with the GHz war again? Haven’t we learned anything? One AMD MHz != one Nvidia MHz. Fermi/GT300 will not run at 1GHz or even 850MHz but will still competes with 5870 simply because it is designed differently.

Non-Chris articles are usually crap.

The problem with overclocking now for a hundred mhz is that it doesn't make much of a difference since its already over 800mhz.

Still like it being a single-slot cooler. Only if it was the 6 mini-port design.

The title refers to the GHz limit imposed by the BIOS on this specific card Pei-chen, not all 5870s or graphics cards in general.
Nor do I ever mention a GHz war, nor do I suggest that one AMD MHz = one Nvidia MHz...

It's pretty clear you didn't read it at all.

Might I suggest that you actually read the article before knee-jerking a sensationalist complaint?
It might make more sense to you...

Interesting article. I expected the 4890s to beat the 5870 because the 4870x2 was generally close and a xfire 4890s ought to be better than that. Still, I wish I had $$ for a 5870, or even a 5850 (later into Xfire with those)- great engineering work by ATI.

AMD's rep said that the explanation is likely that the Radeon HD 5870 is optimized for DirectX 11, and not DirectX 10 and 9 titles. As DirectX 11 titles are released, we'll see the 5800-series deliver even better performance.

This makes absolutely no sense to me, DX11 adds to DX 10 and 9, how can something be optimised for 11, and not 10 and 9?!

5870 should be on par or a bit faster than 4870x2. I don't expect 5870 to be faster than 2x4890.

In fallout: "Once again, the overclocked Radeon HD 4890s in CrossFire take the win at the highest resolution."

Seems that those 4980s are overclocked too. That might count also.

Perhaps the coolant is supposed to flow over the memory first before going through the GPU? That could be why the memory refused to Overclock. Switching could make it harder to OC The GPU though.

The 4890's weren't OC'd, they were run at stock speeds as per the setup info. Fixed the mistake tho, thanks for pointing it out.

As I mention on the last page, i did ask AMD why the 5870 didn't beat two 4890s even thouguh it didn't have to deal with Crossfire latencies. The 5870 has the same stats but faster core and memory speeds, so it didn't make sense to me. AMD's answer was that the 5870 is optimized for Dx11 and we'll see the advantages in future titles.

Still seems odd to me that there's such a large performance disparity, hopefully as the drivers are updated they can squeeze more performance from the 5x00 series.

Yes. once again, I'm not claiming to irst to break a GHz. As mentioned in the article, I was talking about breaking the GHz limit this particular card has in the BIOS.

Cards have been overclocked over a GHz for a long time now.

Correct me if I'm wrong, but don't forget that the 5870 has hardware tesselation. Some of it's archetiture is being utilized for this new DX11 feature. This will also mean, even under DX11 titles, it probably will not give higher framerates, but rather it will give tesselation with great FPS compared to trying to do software tesselation on two 4890's.

I personally find anything over 60 fps undectectable, but I can notice tesselation, so this is a welcome sacrafice.

Well after 5870 is really available (one TSMC get it right... it can take forever in bad case...) the price of new 5870 will become much more competitive against 4890, and even now the 5870 is fast enough, even the 2*4890 is faster option, just like they sayd in the article. Nice article all the way, maybe a little bit obscure, because water cooling is not mainstream hobbe, but it proves where the limits of current 5870 production technology are.
The 5870 seemed to eat a lot of power in extreme settings. It would be nice to see more linear clockspeed upgrades, so it would be possible to define the sweat spot. The maximum speed that don't eat too much power.

Someone else, who shall go unnamed, brought up an excellent point: two 5850's are just above the price of a 5870LCS, but will defeat the LCS none the less. But at that price point, a 5970 is probably the better bet for just plain ease of use.

So....

There isn't any win here, just tie. A 5970>5870LCS>5870>5850, but two 5850's beats a 5870LCS but would be outdone by a 5970. So, no matter what you do, you can't beat ATi's current price scheme.

...

Dang.
