Following our first article that discloses the official specifications of AMD Radeon HD 6970, the highest performing single-GPU card in Northern Islands family, we managed to get a hold of official specifications for the first entry-level part into the HD 6900 Series.
According to AMD, Radeon HD 6950 and HD 6970 represent "The Ideal Enthusiast Card"
AMD Radeon HD 6950 features 22 groups of SIMD units. Under the new VLIW4 architecture, this means there are 352 "processors" i.e. 1408 cores. While this is 32 cores less than its precedessor [Radeon HD 5850], Radeon HD 6950 GPU works at increased clock of 800MHz.

The impressive bit about this "lower spec" part is that it also brings 32 ROP units, i.e. is capable of outputting 32 pixels per clock, with 88 Texture Units. 32 ROPs is the same amount as the Radeon HD 5870 and the HD 6970. This is a change from the previous architectures, where a model bearing the mark "50" would have a cut down pixel output.
At 800MHz, the computing power is set at 2.25 TFLOPS in Single Precision and 563 GFLOPS in Dual Precision [all in IEEE754 format]. To us, it will be quite interesting to see just how much AMD increased the architectural efficiency if this part is compared clock-per-clock with HD 5850.
AMD Eyefinty now should be playable on HD 6950 as well, thanks to the pixel output and the amount of local video memory
The interesting bit about this part is that AMD kept its policy from the Radeon HD 5850/5870 era, allowing for HD 6950 to feature the same amount of GDDR5 memory as the HD 6970. Full 2GB of GDDR5 should give advantage over its direct competition, GeForce GTX 470 [1.28GB] and GTX 570 [1.28GB]. 2GB of GDDR5 memory also enables performance with more complex Anti-Aliasing modes and this card should handle higher resolutions with no issues.
If you’re wondering what the performance of the HD 6950 versus its green competition, you can see that AMD did not foresee the arrival of GeForce GTX 500 series.
Just like the Radeon HD 6970 and its comparison against the GTX 480, AMD pretends that the GTX 500 series does not exist and compares the upcoming HD 6950 with GTX 470, instead of GTX 570.
Again, all will be revealed in just a few days.
