![]() ![]() Iris Pro does very well here, tying the GT 640 but losing to the 650M. ![]() While DirectCompute is used in many games, this is one of the only games with a benchmark that can isolate the use of DirectCompute and its resulting performance. Civ V includes a sub-benchmark that exclusively tests the speed of their texture decompression algorithm by repeatedly decompressing the textures required for one of the game’s leader scenes. Given the ALU-heavy GPU architecture, I was eager to find out how well Iris Pro did in our compute suite.Īs always we'll start with our DirectCompute game example, Civilization V, which uses DirectCompute to decompress textures on the fly. With Haswell, Intel enables full OpenCL 1.2 support in addition to DirectX 11.1 and OpenGL 4.0.
