The CPU benchmarks are heavily multi-threaded, and are optimized for every CPU architectures introduced since the first Pentium came out. The CPU benchmarks are very similar to the old CPU and FPU benchmarks AIDA64 has got, but this time they measure maximum computing rates (FLOPS, IOPS). The CPU measurements however are not obtained via OpenCL, but using native x86/圆4 machine code, utilizing available instruction set extensions like SSE, AVX, AVX2, FMA and XOP. On top of that, the GPGPU Benchmark Panel also has a CPU column, for comparison purposes. For compilation the following OpenCL compiler options are passed: -cl-fast-relaxed-math -cl-mad-enable. Due to that approach, it is always best to have all video drivers (Catalyst, ForceWare, HD Graphics, etc) updated to their latest & greatest version. The OpenCL kernels used for these benchmarks are compiled in real-time, using the actual OpenCL driver the OpenCL GPU device belongs to. Instead, the AIDA64 OpenCL module relies on the OpenCL compiler to optimize the OpenCL kernel to run best on the underlying hardware. The OpenCL benchmark methods currently offered are not specifically optimized for any GPU architectures. Basically any computing capable device will be benchmarked that appears as a GPU device among OpenCL devices. HSA configurations are handled via preliminary support. Of course CrossFire and SLI configurations, and both dGPUs and APUs are also fully supported. Every benchmark methods are designed to work on up to 16 GPUs, including AMD, Intel and nVIDIA GPUs, in any combination. These benchmarks are designed to measure GPGPU computing performance via different OpenCL workloads. It will feature the usual improvements to support the latest and greatest hardware technologies, such as GPU details for AMD Radeon R5, R7 and R9 Series and nVIDIA GeForce GTX 760 Ti OEM, and optimized benchmarks for AMD Kaveri and Intel Bay Trail.īut most importantly, we're introducing a brand new benchmark panel that offers a set of OpenCL GPGPU benchmarks that you can launch from AIDA64 / main menu / Tools / GPGPU Benchmarks. We're rolling out a new major update to AIDA64 in a few weeks.
