AMD Cayman info (or rumor)

[SpuTnicK]

All I wanna to say that VLIW4 SP performs not almost the same as VLIW5 SP
and

"Radeon HD 6900 is Cayman, will be good support double-precision floating-point operations, the performance ratio will be higher than the Radeon HD 5870 . This changed the internal GPU, Radeon HD 6800 for single precision and double precision arithmetic computation ratio is one in 5, while the Radeon HD 6900 was one of 4 points. So even if the Radeon HD 6800 Stream Processor has the same number, Radeon HD 6900 performance of double-precision operations can also increase by 20%. "
