Will Radeon HD 4870 turn up the heat on the GTX 280?

[Fotis]

First 4870 (http://translate.google.com/translate?u=http%3A%2F%2Fwww.expreview.com%2Ftopic %2F2008-06-24%2F1214282167d9273.html&hl=zh-CN&ie=UTF8&sl=zh-CN&tl=en]ATI%204870%20512MB%20DDR5) review by the chinese.Its seems to be beating the GTX260 most of the times by 5-30%.

[Lfctony]

Wow, around 10-20% slower in general than the GTX280, and faster in a couple of tests. That's great performance for it's price...

That translation didn't work for me, here's a fixed one:

Makes it a lot easier to navigate to whatever page.

Still reading...

Ok, first up, looks like the memory overclocks well, they got it up the the ATI CP max of 1100MHz, that's 4.4Ghz effective, and effective 800MHz overclock. Who knows how far the core will go past 790, I wouldn't want to push it without some software to speed up the fan myself.

As for its performance, let's just call it a GTX 270. :) Awesome!

Great, great numbers. It beats the GTX 260 in almost every test (all except Lost Planet and FEAR), and sometimes even the GTX 280 when using high AA & AF at 1920x1200 (HL2 and Bioshock for example).

Even in Crysis it beats the 896 mb GTX 260, and they just tested the 512 Mb 4870!!! (I want to see the 1 Gb version tested under Crysis)

Conclusion: about 20-25% faster than 4850, 5-10% faster than GTX 260, 10-15% slower than GTX 280. I say: IMPRESSIVE!!!

I will wait for more benchs, but I think I'm turning red this time

[brady]

LOL, forget it.

Wow.

[SH64]

Not bad! a ~10% avarage difference to the 280 .. i wonder if the 1GB version can do any better.

[nekrosoft13]

it might, but i still believe gtx280 is better deal, mostly because of cuda

Wait, you mean the word deal hasn't been outlawed from sentences where GTX 280 is the subject? I've lost faith in society.:headexplode:

4870 is under half the price. Can't say I'm thinking about CUDA when looking at those benchmarks and comparing the prices...

[Toss3]

I really fail to see how cuda could be such a big deal. ATi is working with Havok, Nvidia has physX, ATi has a folding client for the GPU and nvidia has a folding client for the GPU, so they match each other in almost every way.

[nekrosoft13]

don't care about folding or physx

hd video encoding has huge potential

Cuda is a bit different than ATI's CTM (Close To Metal). Interesting read.

Inpart:

"Clearly, there are advantages and disadvantages to both approaches, and both approaches ultimately represent attempts by NVIDIA and AMD/ATI to get people who need this sort of GPU-driven math coprocessing power to standardize on one or the other vendor's hardware. Both of these moves are also about building an application base around existing GPU hardware before Intel moves into the market with whatever it's planning to unleash, so that Chipzilla (ideally) finds that the existing customers for GPUs-as-coprocessors are already tied to either AMD/ATI or NVIDIA."

Had completely forgotten about that, but even though it looks nice I'm more interested in decoding rather than encoding and of course lossless audio. ATi is already probably designing their own encoding tool as we write, so just give it some time. :)

Wow.

Wow.

Its not, neckro is just upset because he already purchased a GTX 280 and now after seeing these benchies with a card that cost half as much he is ready to cry.

Aherm.. (http://www.nvnews.net/vbulletin/showpost.php?p=1691871&postcount=60) Posted it in the wrong thread... :D

learn to spell rob, in case you never heard of this thing called a return policy. if i was upset about it i could return it back to store.

[particleman]

wow I certainly wasn't expecting that from the 4870. It almost makes me regret buying my 280 GTX. I mean only 10% less performance but less than half the price I paid. Competition is a great thing though, and at that price I will probably grab one and stick it in my second rig where I was going to put my 8800 GTX but it looks like that is going in the closet.

nVidia has to drop the price on the 260 though and maybe even the 280.

See neckro at least some can admit it.

[Revs]

I think it's fair to say the 4870 is on a par with the GTX260 +/- a few % and prices are gonna be similar. I really want to see 4870 CF against GTX260 SLI. (it's too late for me anyhow but it'd be interesting).

[ginfest]

My first choice would be the 280 but the price is ridiculous. I was then going to go 260 but this 4870 is blowing it also at price/performance. Although I'd rather an NV based card, I hope the prices fall quick or I'll be going red also.

There's not that much in it...

I'm hoping the 260 will OC higher than the 280 because of it running a little cooler.

[shadow001]

I think that given the results above,it's pretty much a given that the HD4870 X2 is going to walk all over the GTX280 and for less money too.


The worse that can happen is that there's no scaling with a game that's just been released,but even then you still get better than GTX260 performance from an HD4870X2,wich is a nice place to be.

maybe not in all test, but keep in mind that 9800GX2 has higher FPS in more then half the test then GTX 280 aswell.

4870 x2 will be competition to 9800 gx2, or nvidia might release gt200 gx2 by that time.

[slaWter]

Since the X2 is scheduled for an August release I guess it'll be up against a GT200b.

Well,keep in mind a few things though:


1:The performance gap between an HD4870 and the GTX280 is only about 15%.
2:Crossfire scaling from 1 to 2 GPU's is anyhwere from 50 to to 70%.(on supported games)
3:A single HD4870 easily beats a 9800GTX by a good 30~35%.
4:A 9800GX2 is basically 2 9800GTX's bolted together,but running at lower clocks.
5:An HD4870 X2 is basically 2 HD4870's bolted together too,but without clocks being lowered


So in all likelyhood,the HD4870X2 will not only outrun a GTX280 by a large amount,but even beat an 9800GX2 by a decent amount too,maybe even 30~35% there,since scaling on SLI and crossfire is pretty similar in terms of percentage gain overall.
