XFX’s Radeon HD 7970 Black Edition Double Dissipation: The First Semi-Custom 7970
by Ryan Smith on January 9, 2012 6:00 AM ESTCompute Performance
Compute tasks, in spite of the name, are not always purely GPU bound. Depending on the task memory bandwidth can also play a significant part – which is why memory bandwidth was the single biggest increase on the 7970 over the 6970 – and our compute benchmark end up reflecting this.
Among our tests only the DX11 Compute Shader Fluid sample fully benefits from the increased clockspeed of XFX’s factory overclock, gaining 9% over the reference 7970. Our Civilization V and SmallLuxGPU benchmarks meanwhile only gain 4-5%, and our AES benchmark only gains 2%, the latter likely due to the fact that the setup time for the program’s dataset does not decrease, only the execution time does.

It would be nice to see "Higher is Better" or "Lower is Better" on every chart. I've been using onboard video, but in order to play BF3 at it's full potential, I'm in the market for a new video card and seeing "Higher or Lower is better" on every chart would help me understand the benchmarks better.Thanks

But what is the max temperature limit?(Or won't AMD tell you either?)

An when i just played Dead IslandIn either Low Medium or high
it went to 78+ heat fan speed 37%
an shut down
it cant handle dead island game
i used to owne a Radeon HD 5870 it had 1 GB
it ran the game in High had no problem at all
how come this grafic card cant handle it ?
Nothing else in my computer gets that hot !
