Yes, yes, I know you're dying to get into game benchmarks. However, synthetic benchmarks set the stage for everything else, helping to demonstrate how well the theoretical peak throughput numbers we've discussed translate into delivered performance.
|Radeon HD 7770||40||20||72|
|Sapphire Radeon HD 7790||56||28||102|
|Radeon HD 7850 1GB||55||28||154|
|MSI GeForce GTX 560 Twin Frozr II||49||49||134|
|Zotac GeForce GTX 650 Ti 2GB AMP!||66||66||99|
In the real world, memory bandwidth plays a part in texturing performance. That probably explains why the Radeon HD 7790 falls behind the 7850 1GB here.
|Radeon HD 7770||1000||72|
|Sapphire Radeon HD 7790||2150||102|
|Radeon HD 7850 1GB||1720||154|
|MSI GeForce GTX 560 Twin Frozr II||1760||134|
|Zotac GeForce GTX 650 Ti 2GB AMP!||2066||99|
Wow. The 7790's two geometry engines do wonders for tessellation performance, especially when paired with a 1075MHz core clock speed, as on the Sapphire card.
|Radeon HD 7770||1.3||72|
|Sapphire Radeon HD 7790||1.9||102|
|Radeon HD 7850 1GB||1.8||154|
|MSI GeForce GTX 560 Twin Frozr II||1.2||134|
|Zotac GeForce GTX 650 Ti 2GB AMP!||1.6||99|
The 7790 comes out on top here.
We'll have to stop our theoretical explorations here, unfortunately. I normally include LuxMark, an OpenCL-accelerated ray-tracing benchmark, in this set, but it refused to run using the drivers AMD provided for the 7790. Oh well; moving on...
