Chiphell, a Chinese tech site has leaked out some specs on the upcoming Barts series from AMD.
The upcoming Barts series will be the successor to the very popular HD 5750 and 5770 boards. What's impressive about the new Bart boards, is it will compete with the GTX460. Not only will it compete, but it's upgraded it's memory bus from 128 to 256bit.
Barts XT will have 12 SIMD's, 960 shaders, 48 texture units and 32 ROP's. To compare this to the current Juniper XT (5770), the current board has 800 shaders and 40 texture units (with the 128bit bus). Core clocks should be about the same (850mhz), but with the internals being tweaked - it looks like this might become the favorable board of the upcoming gaming season in November. Barts XT looks to have a TDP of over 150W.
Barts PRO will feature 800 shaders, 40 texture units and 32 ROP's - this is pretty much smack on what the 5770 is now, but with the increased 256bit bus, it will be interesting to see how this performs against the current 5770 and the competitions GTX460. Barts PRO will have a TDP of under 150W.
Memory wise, the XT variant will have 1GB and the PRO version will contain 768MB. By going on the above specs, Barts XT might hover around 5830/5850 performance - which again, makes it very good value for money if AMD can keep the price south of $200 - $220.
The 6 series from all these leaks is starting to form a very good picture for not only AMD but consumers. Consumers like you and me are the ones that win in these battles.
It looks like the Barts boards will be a winner... let's just hope NVIDIA don't have a cow, man.
