AMD Radeon HD 7870 GHz Edition & 7850 Video Card Review

3DMark 11

3DMark 11 is the latest version of the worlds most popular benchmark for measuring the 3D graphics performance of gaming PCs. 3DMark 11 uses a native DirectX 11 engine designed to make extensive use of all the new features in DirectX 11, including tessellation, compute shaders and multi-threading.

Since Futuremark has recently released 3DMark11 we decided to run the benchmark at both performance and extreme presets to see how our hardware will run.

3DMark11 Performance Benchmark Results:

In Futuremark 3DMark11 with the default Performance Preset we found the AMD Radeon HD 7870 GHz Edition scored P6720 and the Raden HD 7850 scored P5594. Not bad scores at all!

3DMark11 Extreme Benchmark Results:

We know that 3DMark11 is fairly math or compute heavy, so it didn’t come
as a big surprise to see the AMD Radeon HD 7950 and the Radeon HD 7870
GHz Edition performing so closely. AMD says the Radeon HD 7950 has a
compute performance rating of 2.87 TFLOPS and than the Radeon HD 7870
GHz Edition comes in at 2.56 TFLOPS. This makes the Radeon HD 7870 GHz
Edition ~10.8% slower in terms of compute performance and in 3DMark11 with the Extreme preset we found it to be ~9.6% slower. By the time you factor in the lower memory clocks, fewer stream processors and all the other reductions it makes sense.
