AMD Turks GPU detailed

Written by Slobodan Simic

AMD Radeon HD 6570 and Radeon HD 6670 cards
Guys from pcinlife site managed to get their hands on AMD's upcoming entry-level Radeon HD 6570 and Radeon HD 6670 cards that will be based on the 40nm Turks GPU. The Turks and the high-end dual-GPU Antilles are both scheduled to make their appearance sometimes during this quarter.

Both SKUs based on the Turks GPU have 480 Stream processors, 16 ROPs and come with a 128-bit memory interface. The first SKU, or the slower one, will be known as the Radeon HD 6570 card. This one ends up clocked at 650MHz for the GPU and will feature 2GB of GDDR3 memory clocked at 1800MHz. The "faster one", Radeon HD 6670, ends up clocked at 800MHz and features 1GB of GDDR5 memory clocked at 4000MHz.

These two should replace the Radeon HD 5570 and the 5670 cards. Of course, you might want to take these specs with a grain of salt since these cards are still far from an official release.

So what will be the 5770 replacement? The 6850?

5770 and 5750 are being "Rebadged" as 6770 and 6750, only available to OEM partners (you can't buy them retail). Take that as you will.

sadly.

a 5770 with a decent memory bus would rock :/

5770 has enough memory bandwidth. You can confirm that because memory oc has no effect in performance whereas gpu overclock increases linearly the performance.

GPU clock naturally gives more performance but when you play on FullHD and with AA, it loses a lot more FPSs then it would be the case with 256bit. A mid class card with a low class memory bus is non sense.

I don't understand why the slower, cheaper card has twice the memory. Is GDDR5 that much more expensive than DDR3 that they can pack twice as much on a card and still sell it for less?

Edit: I checked the link, and it says the 6570 will have GDDR5 and the 6670 will have DDR3. Not very credible info at all.

The 6800 series is the successor to the 5700 series. Also, the 5700s are rebranded as stated above.

It might be on par with the 4770 in performance...at least a lot better than the 5650/5670... :-)

If this leak is real then it's less than 10% faster than my hd5670 in 3dmark06. The extra ROP's and TMU's will certainly help more than the extra shaders, but to be honest this appears to be more of a consolidation of AMD's performance per mm2 advantage over Nvidia and improving their margins than it is any large improvement over Redwood.
