AMD Radeon HD 6790 Specifications Revealed

Not long after AMD's upcoming Radeon HD 6790 was first revealed, Nordichardware is reporting the final specifications for the HD 6790. It is indeed a Barts derivative, codenamed Barts LE and it is to the HD 6850 much like the HD 5830 was to the HD 5850. The HD 6790 disables a further 2 SIMDs from the Barts die, now left with 800 SP and 40 TMU. The GPU is clocked at 840 MHz, so thus far, it looks much like a HD 5770. However, the HD 6790 thankfully retains all 256-bit memory bus with surprisingly the same memory bandwidth as the HD 6870 - more than twice than the HD 5770. All 32 ROPs are retained too - once again, twice that of the HD 5770. The HD 6790 also features the enhanced Barts architecture with improved tessellation, and this along with far superior pixel fillrate and memory bandwidth are the areas where the HD 6790 will gain a significant advantage over the HD 5770 (and also the GTX 550 Ti).
