ATI Radeon HD 4000 Series discussion

I want somebody to break the NDA as I said, you sacrifice one so that the rest of the team gets satisfied.

Well I won't ask that. But at least someone with one of this cards could tell something like: "you'll like what you're gonna see" or "don't get to high expectations"

Latest rumours: nVidia score are pretty much reliable ATI's score less at this moment.

Vantage Xtreme settings, 1920*1200+4aa+16af

GTX 280 = X4098
GTX 260 = X3782
9800GX2 = 3608
HD4870XT = X2595
HD3870X2 =2582
8800ULTRA = 2.403
HD4850PRO = X1981
HD3870 = X1440

Just rumours. I think we'll see more benchmarks soon.

I don't the 4870 results are legit (though gt200 ones probably are) because we're talking about 50% more shaders and double the texture power, the increase should be far more than 25% (over the 3870) for such a high level of detail.


Also 3dmark vantage definitely seems to suit nvidia cards far better than ati cards, and its not a game so I don't really think 3dmark vantage is a good representative of what games will show. However, if the gtx 280 spanks the 4870x2 results by a large margin in 3dmark 06 which is favors the r600 cards, then its safe to say the gtx 280 will be the undisputed king for benching and probably games too.

Why not? The HD4870 score seems more then logic. HD4870 seems to be 80% faster then the HD3870. It was rumoured the HD4870 would be 50% faster in overall performance, but the HD4870 has far better AA performance, so 80% doesn't seems wrong to me.

Remember that the shader clock on the 4870 is rumored to be 1,050 MHz (200 MHz over the core clock). When you take this into account, the 4870 has (in theory) twice the shader power of the 3870, not 50% more.

Yeah I realize that, but the chart initially showed the 3870=4850 and something like x1950 (which I quoted) and that's what I saying, way too low, should be 50%+, 80% sounds perfect to me actually

Oh and AliG it says the 3870 scores 1440 while the 4870 does 2595.
Oh well, I won't make any conclusions about their performance until the cards are officially released.

As I said, look at what I quoted, the poster fixed it

Once again, I understand this

Kinda what I expected for ATI but definitely below expectations as far as GTX 280 goes!

What this means is that X2 from ATI would probably win against GTX 280. Since 3870X2 is almost 80% faster than 3870 we can assume 4870X2 to get around X4600 points! Way above GTX 280.

Why? 1 GPU smacks 2 GX2 GPU's to the ground. Not bad I would say. I know people always hope for more power, but seriously, if the GTX-280 is really this fast, then nVidia did a real good job.

Ofcourse it's fast, problem is I think most fanboys expected much faster. And I don't think those numbers for GT200 are true. I think they are higher than that.

It should be like 8800GTX vs 7950GX2 but even more in favor of the GTX because nV has said that this time the preformance increase will be greater than previously.

Unless they talk about 8800GTX->9800GTX

[003]

Unless they talk about 8800GTX->9800GTX

They specifically said something along the lines of:

"The transition to the GTX280 from the 9800GX2 will make the transition from the 7800GTX to the 8800GTX look like peanuts by comparison"

I hope that holds true.

Hmm, those scores look pretty good for the 4870XT. Just a bit faster than the HD3870X2 (as many said it would be comparable) and much faster than the 3870. And with that amount of AA and AF, looks like they fixed a lot of the AA and AF issues. Plus, if ATI cars in Vantage aren't doing so well and can increase in performance once fixed, it will certainly be a good % faster than the Ultra, which at those settings still beats 9800GTX. So it's in line with the idea that the 4870XT is ~20-30% faster than the 9800GTX.

HD4850PRO looks like a great deal at its price range too.

Hopefully those GTX280 scores will be higher, but at the same time, in synthetic tests, dual GPU cards tend to be more optimized than real-world performance would indicate.
