ATI Radeon HD 4000 Series discussion

[zerazax]

I'm confused. Are you saying that the 850MHz core speed and 1050MHz shader shader speed are incorrect? And are you also implying that the shader speed may still be the same as and tied to the core speed?

That would be a real shame.

I think he means that we don't really have any idea if they are separated or not, and that ATI hasn't settled on final clocks.

However, i think with Computex starting essentially in a couple days, the clocks will be close to final if not already settled there

If they're already shipping to Retail/OEM then AMD know the final clocks & they have been set. At least for the 4850.

[zerazax]

Yep 4850's should be already set, especially since the box pictures and all that are out there

[purecain]

if it wernt for fast cars/moterbikes women and new gpu's life would be soooo dull...
it'll feel like christmas when these cards arrive...

not long now

Original graph from JC:



After some modifications...



Catalyst 8.4:
· A picture is worth a thousand words -> WiC avg FPS.

Catalyst 8.5 :
· Call of Juarez DX10: Performance increases up to 12% on systems containing an ATI Radeon HD 3000
· World in Conflict DX10: Performance increases up to 25% on systems containing an ATI Radeon HD 3800.
· Higher performance gains are noticed on systems contianing an ATI Radeon 3870 X2.

Remember the part where they had 800SPs?

That's not entirely impossible either.

[Bo_Fox]

Overall, the 4870 Pro is 5% faster than the 9800GTX, right? And the 4870 XT is 25% faster than 9800GTX?

If yes, then I'd say it's a home-run for ATI (as they claimed to fix the AA issue).

[philbrown23]

that graph saying that the new nvidias are fatser than the ati's, was produced by nvidia, of course it's going to say that nvidia is a better card!

You say that like it's questionable/debatable

it's a gt280 vs a 3870x2, of course the gt is portrayed as a better card.
Everyone would do so

There is no such thing like 4870 Pro and 4870 XT... You have:

HD4850 (RV770pro)

HD4870 (RV770 XT)

HD4870X2 (R700, 2 RV770XT(?) same PCB)

madcho what a load of rubbish those graphs are! what exactly are those random numbers on the side? is it trying to say that the 3870x2 gets 1fps in 3dm vantage? also trying to draw a conclusion based on hypothetical scores?

percent, 3870x2 is always 1 (100%).

ever seen scientific graphs? they quite often have such a scale as well. you just divide the measured value by the one you want to compare it to.
in these graphs it's the values of the HD-3870X2.

why do they do this? quite easily, you can see the differences very well and you have a value without unit. for instance in 3D06 you got points, in most other cases you got FPS. this way you can put several bars in one graph...

wrong was, that NVIDIA began with 0.8, but thats marketing!

Latest rumors, but i don't know where it comes from.

HD 4850 => 10 Prozent schneller als 9800 GTX
HD 4870 => 40 Prozent schneller als 9800 GTX
HD 4870 X2 => 30 Prozent schneller als 9800 GX2

Gut, das ist sehr schnell!

RV770 PR SAMPLING PROGRAM






http://www.ati-forum.de/allgemein/ne...-presentation/

How we reported some days ago, the new Catalyst 8.6 contains the support of the RV770 and more further models of the new 4000 series. Today we can show with a save source you further models, under all the IDs of the 4400 series:

HD4870 40% faster than 9800 GTX, yet HD4870 X2 only 30% faster than 9800 GX2?!

I find this strange. That would mean HD4870 X2 scales extremly poorly.

I call this rumor BS.

[Telo]

What is the current ETA on these cards please?

[bigslappy]

sub'ed

HD4850 middle June. HD4870 July I guess due to GDDR5 shortage.

seconed.

[perkam]

seconed.

It is called diminishing returns from the second GPU, and can be seen in early GX2s as well when drivers had not fully matured.

THe GX2 has been out for a while, hence the lower result due to tweaks that may still be necessary on the 4870X2 to optimize the performance from both cores.

I am NOT stating that the source is correct, just that the above argument cannot be used as a basis for discrediting it.

Unless of course HD4870X2 clock is lower than HD4870. But that would be a step back from HD3870X2 which actually had slightly higher clock than HD3870.

Anyway drivers could be the reason too.

On the other hand I find the performance of HD4xxx kinda high. Actually much higher than what I was expecting. Thats also a reason why I call it BS.

Thanks much for the quick reply. I'll sub this thread and keep an eye out for the 4870x2 to replace my HD2900XTs. Thanks again.
