RV670 info

[KasuCode]

If you were looking for a good crossfire setup "Redeemed" this might be the card for you.





R600 original design didn't include the UVD and now we know that AMD made an effort to include this nice video features in this quasi mainstream part.




RV670 will offer a great performance but at the price of a mainstream or performance mainstream part and UVD was something that we all missed at the original R600 design.




The other thing that is improved from the original R600 design is the DirectX 10.1 support as well as Shader model 4.1 support. All it all his RV670 will probably turn better than anyone has expected.

RV670 will be a mainstream part that ATI plans to offer from November on but there is someething that Nvidia doesn't expect from this chip. RV670 specification is actually an improved version of R600 design with PCIe 2.0 support and Shader model 4.1 support but the chip will be almost as powerful as the R600.



The only thing that won't be as good as the R600 is the memory controller that is cut in half. The new RV670 will feature 256 bit memory controller but it will have faster clocks to compensate.




At the end we expect a bit slower card than the original R600 at $199 to $249 prices and this might get Nvidia to start worrying.

That's a rather interesting HSF design.

So.... now we need benchies. :captnkill:

[Redeemed]

Hmm... I could easily see two of those in CrossFire...

Yeah, I'm still holding out for benchies, and I hope this comes with atleast a 512MB Variant, though 1 GB would be awesome as well. :D

Here will be no 1GB part, RV670 have 2 SKUs: Radeon HD 2950 Pro 256MB GDDR3/512MB GDDR3 $229/$259? and Radeon HD 2950 Pro 512MB GDDR4 $299.

When in single mode

The RV670 will work between 750MHz and 825MHz and there might eventually be even a slower version of the core for some custom slower cards.



The 825MHz is the top speed of the chip and you will probably be able to overclock it even more but DAAMIT wants to stay on the safe side.




The clock speeds can chance for the shipping date but at least this is what you can expect.

According to theoretical numbers RV670 will be as fast as R600. I guess this is ATI's dark secret as RV670 is indeed an improved version of its R600.



The RV670 at 750 MHz has 480 Gigaflops processing rate, while the R600 at its 742MHz has 474Gigaflops which implies that the chips will have the same performance at the same speed.


ATI's dark secret is that at maximal 825MHz the chip can gain an additional 50+ Gigaflops but we still believe that the RV670 has to lose to R600 in high resolution with FSAA and Aniso due to its 256Mbit memory interface.


RV670 in its three iterations comes in November.

The base of RV670 design is the R600 architecture and ATI learned a lot from its mistakes. Nvidia overclocked Shader speed really boosted Nvidia's performance and ATI simply could not catch up.

It was a time for a new strategy. The RV670 is a redesigned and improved R600 core done in 65 nanometre with official support for PCIe 2.0. The base R600 design is improved with UVD and this is a something that was missing from this big card.

ATI added Shader model 4.1 and DirectX 10.1 support for this new core. At the same time the company claims that it managed to improve antialiasing performance and at the same time that it managed to reduce the memory interface bandwidth. The anisotropic texture filtering quality is also improved and at the same time ATI managed to reduce the transistor count.

We will soon see just how fast this new card really is.

With X38 boards out and these new AMD cards, things could get interesting. If AMD wants to do things right, they now need to ensure widespread bug free driver support for Crossfire in all games! Do that, and we have a winner that can compete with nVidia again.
