Radeon HD 6700 detailed on slides

Written by Slobodan Simic

Full specs for Bart XT and Pro

Following the leak from Chiphell a few weeks ago, a forum member on Pcinlife published a full slide taken from the what appears to be a legit AMD slide. This time we can see full details of both Radeon HD 6750 and Radeon HD 6770, or simply Bart Pro and XT.

The slide compares Radeon HD 6700 series to couple of Radeon HD 5700 and 5800 series cards, which gives you a more clear picture of what we can expect once these cards show up at the market. The Radeon HD 6750 should be placed and perform close to the HD 5850, and although it has the same clocks as the Radeon HD 5850 (725MHz for the Core and 1000MHz for memory) it will have less Stream Processors, 280 compared to the 288 on the HD 5850, less texture units, 56 compared to the 72 on the HD 5850, which also means less compute performance that ends up at 1624 TFlops compared to the 2088 on the HD 5850.

The HD 6770 ends up close to the HD 5870. It has the same amount of Stream processors, 320, although they are a bit differently organized. It has less texture units as well, so the HD 6770 ends up with 64 (16x4) compared to 80 on the HD 5870. This one should end up clocked at 900MHz for the core and 1050MHz (4.2Gbps) for memory.

The specs look quite good for now, and it looks like AMD will sell these ones quite easily. This also means that Cayman, high-end parts, will end up a lot faster than the HD 5800 series, at least when compared how well the HD 6700 compares to the previous HD 5700 series.

You can find the slide here.

Update: We're sorry for the inconvenience and confusion caused by a part of this article, as it had to be noted that the HD 6770 has the same amount of SPs per module as the HD 5870 and not the same amount in total. The HD 5870 of course has 1600 SPs orginized in five modules (320SP x5), while the HD 6770 has the same amount of SPs per module but only has four modules thus ends up with 1280SPs. Same thing goes for the HD 6750 that has four modules with 280SPs per module so ends up at 1120SPs, while the HD 5850, of course, has five modules with 288SPs per module, or with simple math, 1440SPs.
