HD5970 Reviews

[tajoh111]

Ever heard of CPU limitation? Your babbling

The 5970 is limited by the CPU, it cannot perform at 100%, even if OCed to the levels of 2 5870 because the CPU is to slow, even an I7 at 4.2ghz. We need 5Ghz Gulftowns really fast.

Don't be unrealistic and a fanboy. If Anandtech is running into CPU limitations now with top end cpu which are not likely going to be eclipsed by anyone that not buying a gulftown, than most people are going to run into cpu limitations anyways which makes these results relevant than imaginary non cpu bound results.

Real performance matters more to the general public than performance imagined by a 6ghz core i7 with liquid nitrogen cooling.

This is more of a limitation of performance limitations of the 300W envelope kicking in.

Any news for water blocks?

I'm not a fanboy, the 5970 is limited by the CPU.
I own an 8800GT and i want to buy a GTX 275 in short time, to go with my new 920 D0. So, i don't base my GPU opinions on fanboyism, i buy what is the best bang for the buck.

But, we need higher performing CPUs to really stress a 5970.

Your right its limited. Its limited by r600-r700 technology. The performance yields from just upping the specs and quantity were incredibly not linear from 4870 -> 5870. 5850 CF is the same speed as this card, yet it has 10% less shaders.

If AMD just doubled the specs again from r800 to r900, there would be even less of a performance gain.

[Florinmocanu]

i'm not talking about architecture scaling between a 4870 and a 5870.

The reason why 5850 CF, 5870 CF and 5970 do not scale that well from the single cards is because they are CPU limited.

less power usage than the 4870x2?

Win.

maybe at 1024x768-1280x1024 IE bench resolutions
Gaming at 19**x**** I doubt raising the cpu speed from 3.8ghz (techpowerup article) to 4.2ghz would net you much gain at all.

Check the OC results, 750 1000 to 950 1300 increased frames %20 in some cases. That wouldnt happen if the card was being choked by the cpu.

Bold for truth.

Any QUAD XFIRE? reviews of quad xfire???
I would love to see that !!

Danger Den is the only one that has showed a block off. Expect more in the coming weeks. However it's a moot point if there are no HD5890's to be found.

please note that unlike other vga reviews i tested the oc performance at 2560x1600 instead of 1920x1200 to avoid cpu limitation

not possible. maximum 4 gpus

^ guru's had quad fire..and the scaling was pretty impressive imo on most tests


or was he referring to it as 4 5970s?...ignore response if so

Hey, i was referring to 2 x HD5970s , so thats quad. I saw the review, pretty good man, over $1500 in GPU power though

"We are in high-quality DX10 mode with 8x AA (anti-aliasing) and 16xAF (anisotropic filtering). And ooh .. i just felt something move in my pants"

on a serious note it scales surprisingly well!

[Manicdan]

just read the TPU review, i was very shocked at how well this did for cyrsis, (over 100% scaling?)

i hope im not being dumb, but were the 5870 and 5970 using the same drivers?

[D749]

thats wallpaper worthy

My new work desktop wallpaper. Good thing I use two monitors.

[W1zzard]

oh just two cards? been there, done that

[Monstru]

Yes, it does. I was amazed in some situations, most of the problems that I ran into with older generations are gone now. I think that the drivers for HD5xxx series have imporved a lot compared to how drivers were for other generations at launch. I had all sorts of problems with 2 x 3870X2 and 2 x 4870X2 back in the day, but no problems with 2 x 5970.

That's not an r600-r700 limitation. You are not going to see linear scaling by simply doubling the number of execution units on any architecture. Even an nvidia one.

how is $599 x2 over $1500?

I believe its mainly 3 games severely bottlenecked which guru3d illustrates the severe bottleneck in its graphs: COD WaW, RE5, and Fallout 3. I agree also this card is ahead of its time in terms of raw power.

Games we have right now and an overclocked i7 @3.8ghz is barely keeping up.

Any idea if ATI is going to provide the software voltage tweaking tool released to reviewers?

[dan7777]

when will these be available in the uk ?
