Radeon HD 6870 is a 255mm chip

1.8 billion transistors

We are still getting some last minute details about Barts PRO and XT. This time we can tell you that Barts PRO and XT parts feature a 255mm2 die size. This is quite good as Radeon HD 5850 and 5870 had 334mm2 size. The chip is almost 30 percent smaller and the new one consumes up to 151W in the XT version, which is less than the Radeon HD 5850 series. Radeon HD 5850 had 2.15 billion transistors while the Radeon HD 6850 and 6870 have 1.8 billion.

Radeon HD 6870 has a total memory bandwidth of 134.4 GB/s, 900 million polygon/ sec geometry throughput and 14 SIMD engines, four less than Radeon HD 5850. the total number of stream processors is 1120, while HD 5850 has 1440, the 6870 has 56 texture units, 128 Z/stencil ROPs and 32 color ROPs.

AMD claims that with a good CPU it scores 7730 in 3Dmark Vantage Extreme, most likely with a six core top notch CPU. The maximum board power is as we previously reported 151W, while the idle power stays at 19W which is also better than Radeon 5850's 27W.

Launch day is as Friday the 22nd, as we've already said a few times. All this comes from the mouth of Eric Demers, CTO of graphics group and a very nice chap. Of course he didn't tell us this directly, but these specs is what he showed to AMD's tame press.
