![]() We believe in a healthy blend of synthetic tests (for isolating specific performance attributes) and real-world application benchmarks. In the end, the fastest cards sped up almost 20 percent in my new benchmark system than in the old workstation. This might not reflect the average workstation very well (though Intel does sell a Xeon E3 configured very similarly that's often used in workstations), but it does give us a less constrained look at the differences between high-end graphics cards, some of which went from almost identical performance to huge performance deltas after transitioning to the new machine. We finally settled on a desktop-oriented processor with a high clock rate and fast memory. Differences between the lower-end cards were much smaller, indicating the bottleneck. Under both platforms, the top-end boards we benchmarked landed very close together in the SPECapc tests, along with apps that didn't benefit from heavy threading, but instead needed big instruction-per-clock throughput from the host processor. The same went for a system with two Intel Xeon E5-1660 processors running at 3.3 GHz. The dual-CPU workstation based on a pair of AMD Opteron 4284 processors (Valencia, 3.0 GHz with Turbo Core) that we used last year turned out to bottleneck the higher-end graphics cards in this round-up. : Nvidia's Quadro K4000 And AMD's FirePro W7000 Get RecommendationsĬhoosing the supporting hardware to benchmark with put us in a bit of a quandary.: OpenCL: Simulation And Function Results.: OpenCL: Encryption And Decryption Results. ![]() : OpenCL: Double-Precision Financial Analysis Results.: OpenCL: Single-Precision Financial Analysis Results.: Single- And Double-Precision Results.: CUDA: iray Renderer + 3ds Max Results.: OpenGL Synthetic: TessMark (OpenGL 4.0).: OpenGL Synthetic: GPU Caps Viewer PostFX.: OpenGL Synthetic: Unigine Heaven, Sanctuary, And Tropics.: SPECviewperf 11: TCVIS And SNX Results.: SPECviewperf 11: Pro/ENGINEER And SolidWorks Results.: SPECviewperf 11: LightWave And Maya Results.: SPECviewperf 11: CATIA And EnSight Results.: Benchmark System, Drivers, And Software. ![]()
