Official AMD Radeon 6000 Series Discussion Thread

[mastrdrver]

Anyone have that picture that was posted in October that first showed the 1500+mhz GPUz shot for the 6970?

That may not be real. The zero is smaller for "30". The "3" in 32 appears to be a different font. Also, the "0" in 1920 also appears to be smaller and doesn't seem to line up flush with the other digits as 0's in 1600 beside it. But we will have to wait and see once the card is released though.

Unless that picture is a lower resolution then the one posted some people are over scrutinizing this.

Now given the pic posted......

I think it makes sense because the shader to texture ratio jumps to 5:1 from the 4:1 that it has been at for a couple generations now for ATI. Looks like there are 5 texture units per SMID cluster now too.

What I want to know is if the setup area has changed from Evergreen since I think it is kind of obvious that it was limited in Evergreen when compared to Barts.

We don't know if it's true or not but the skepticism is warranted. The placement of digits don't look right and that is labeled as slide 72. While the leaked slide for 6990 is slide 6. A lot of that just doesn't make sense. But like I said we have to wait until it's officially release to see.

 

[mastrdrver]

Unless you know the order of the slides I don't understand how anyone can come to a conclusion based on slide numbers.

HD 6970 (Details+picture)

Sorry I did not know where I put the news

 

[micropage7]

from the spec thats kinda cool, at some point it looks like refresh from 5870 now with new architecture, just wait for the final version

 

[FordGT90Concept]

Eh? It's a dual GPU card (dual graphics engine)? It's pretty disgruntling that the 5870 is a great deal faster than the 6870 and if it took them a dual GPU to beat the 5870 in the 6970. Not to mention, AMD killed 64-bit FPUs in the 6 series so overall, 6 series just sucks. I hope my 5870 doesn't die because I'm not too crazy about the 6 series.

 

[crazyeyesreaper]

dual graphics ENGINES slide said nothing about dual gpu man read the slide carefully. From the looks the die layout shot above seems to look more like a dual core gpu then a dual gpu card. Should be just fine as it is. Benchmarks and reviews are what we really need tho.

 

[Lionheart]

Im no GPU expert but they could of at least gave it more ROPS and increase the memory bandwidth a tad more

I can't believe these misconceptions still exist on TPU

The 6870 is NOT the replacement of the 5870.
The 6970 is NOT the replacement of the 5970.
The 6970 is NOT a dual GPU card, the 6990 is.

NDA is not up, it was extended to December 13th.

The point is still the same. Instead of increasing the power of the "core," they decreased it substantially and added a second. One step forward and two steps back (as is the case with the entire multi-/many-core movement).

Has there been any information as to how these two "cores" are programmed? Is it essentially on-chip Crossfire? There's a lot of games that don't take much liking to Crossfire/SLI in the first place so there could be a huge penalty in a lot of games for taking that approach.

But you're absolutely right: we need benchmarks comparing the 6970 to the 5870. No matter how it comes out though, 6970 can't do 64-bit floating point operations like that 5870 and that's a major downside (not today, but tomorrow). Virtually all CPU processing has already moved to 64-bit floating point numbers and most modern CPUs are capable of handling 128-bit floating point values. Okay, so maybe the gaming industry will refrain from using 64-bit for quite a while yet because of the increased GPU load but still, it will eventually become the norm as environments get larger and models get more detailed. There is already existing demand for 64-bit in GPGPU applications which AMD is already way behind NVIDIA in (CUDA probably has 3-4 to 1 market acceptance over Stream).

Why put more when you can increase their efficiency ?



And read well the slide : higher of 160GB/s .... not 160 ..... they just don't want give any infos about the clock speed. we believe the 2gb of the 6950 - 6970 will be clocked between 5000 to 6000mhz

Yes, thankyou for clearing that up for me as I said before, im not a GPU expert, I was only taking a piss

 

[GC_PaNzerFIN]

Oh look it is new power limiter! Where are the haters now? Still busy complaining at GTX 580 limiter?

It's only the uncore who are doubled, this mean 2 Vertex Assembler, 2 Rasterizer, 2 Tesselators, who work separately.. this is the front end of the core.. not the core... for the rest the architecture is completely modified, including a refont of the GPU compute parts. ( sorry maybe i have not understand what you mean, it's the cfx you was speaking who have maybe confuse me )

ahem
5870

5770

apparently you didn't pay much attention to the 5870's architecture.

5870 literally is 2x 5770.
just the same as 5850 literally is 2x 5750.

while it seems we do not know the card that will be 1/2 the 6970 (is there is one) it's the same configuration as the 5870. seriously I swear people's memory is like half a seocnd long.

Hey mastrdrver,

Here is your proof that slide 72 was photo shopped. The real one is in the post I quoted above. Yes, we do need to scrutinize information if the image itself doesn't look right.

In other news, the 6900 series will include both MLAA and EQAA (Enhanced Quality Anti-Aliasing).

Nice work Columbo.





Edit: Oh... just one more thing...

Another leak but for Antilles card. Mayeb confirms 1920 sp's for single caymen.

Looks like slide show for sure on a big screen.

Sorry but that's another fake slide :shadedshu.
Proof here.

If there are any blems (blemishes such as blurring, blacks outs, odd fonts, different size fonts, etc) with any other slides scrutinize them. Another dead give away any underscored red words indicating a misspelled word. That indicates that slide is not the final presentation slide.

hey guys..
Did you know, when Shappire 6870 non reference + factory OC'ed, release .. ??
