ATI Radeon HD 4000 Series discussion

4870 X2 looks good.

That depends on how well the mcm design will do compared to the regular ol' xfire. Hopefully the performance will be a true 2*single die situation (which looking at how well core 2 duo and k10 scale multicore wise that may finally be the case) and that will give them the power they need for a high end gpu. If not, then I'll still be happy if its around $400 USD

On the chiphell's graphics roadmap was appeared a RV770 with specs 800SP/32TMUs . Real or not ?

Probably not, but let's just stick to this statement:
Prepare for the worst, hope for the best.

RV740 240 24 12 256-bit

256-bit interface isn't happening on the 4650 (the first midrange products) if one knows anything about ATI midrange history.

There is a discrepancy between the west and the east regarding the number of SPs. Here in the west, most stories claim 480 shaders, while most in the east says 800.

In my opinion, 480 is the more likely of the two, but I have a hard time believing that would bring any more TMUs. They would likely just add 160 more shaders then, and no TMUs. Although, I should say that I've been told that there will be more TMUs.

With 800 SPs it seems more likely with 32 TMUs. But then we have the fact that the core is said to be only 830 million transistors. 480 shader processors and 16 TMUs from a mere 170 million transistors. Somehow I don't see that happening...

Actually I'm willing to bet the rv740 will have a 256bit memory interface, as ati needs something to compete with the 9600gt. If it does have 256 bit memory, then we'll be seeing a monster midrange card. Thing about it, it has the same amount of TMUs as the r600 did but less shaders. So in other words it won't be any where near as bottlenecked, and if you look at how the r600 performed with roughly 2/3rds of its power being used, we'll see something comparable to the 3870 for the midrange.

I hope when the real numbers are out the 4870 would have a really good c/p ratio.

Probably not, but let's just stick to this statement:

QTF, too much hope usually leads to disappointment.

1GHz core plus gddr5? sounds great

[flopper]

now it sounds good with 4870.

I dont know about him being an AMD fan, but he has been known to add to the FUD:

When clocked at 3.0 GHz and equipped with two overclocked HD2900XT cards in CrossFire, Agena FX or single-core Barcelona smashed an index of 30,000 3DMarks 06.
Yes, you’ve read it right - the barrier of 30,000 was passed to, barely, 30.031.
We know that there are different systems floating around, and we have no doubt that leaks will start appearing after this article goes live. Knowing what was the overclock of Kentsfield processor, Intel Yorkfield has quite a big job to do. One thing is clear, though. Intel needs Nehalem, and it needs it badly.

This was just enough for me to think twice before read his articles. The most of his articles is about AMD.

1,05ghz coreclock on an engineering sample is amazing. ES cards are always lower clocked then retail cards. What would be the retail speed? 1100mhz would be crazy.

[Hornet331]

i doubt that we see 1ghz core clocks with 55nm, maybe with 45nm but that will take some time.

[HKPolice]

I can confirm: under 1Ghz clock for the 4870, probably 900 and 800 for 4850.

I'm definately going to be upgrading to a 4870 instead of a second 3870.

Im no fanboy, but its just because I have a crossfire motherboard, so theres no point buying an Nvidia card if I cant add a second one later.

Also the 4870 should be $300 / £150 I hope, which will make it worth it if it really is going to be as good as expected.

I'll layback and wait on one of the Dumped 3870 and run Crossfire on my next system.

I strongly suggest you to not doing that, you won't be pleased with the results

[[XC] gomeler]

I hope the GPU clocks aren't too high.. I want to be able to get some wicked overclocks

I'll layback and wait on one of the Dumped 3870 and run Crossfire on my next system.

Not suggested unless you get an X38 board. Better off going with a stronger single-card.

[fireice2]

single GPU gives less headaches as well.

[AliG]

QTF, too much hope usually leads to disappointment.

True words to live by. I'm afraid to hope for shanghai because of barcelona's poor track record, but by doing that if it does perform well it'll be a nice surprise.

But I have no doubt the 4870 will be a very strong performer and will spank g92b unless that has some more shaders

[AliG]

Both GDDR3 and GDDR5 memory will be supported by the chip, but ATI itself will only be offering GDDR5 cards.

Very interesting, does this mean ati will start selling their own cards again? I know they didn't with the r600 cards but they did before them

[Eastcoasthandle]

we should see leaked benchmarks soon. Very soon.
