Thanks to using all CPU cores for the cache benchmarks, you will get dramatically different cache bandwidth scores than with the old benchmarks. We've also implemented multi-threaded cache benchmarks, that now include support for the latest AVX and AVX2 instruction set extensions.
It is especially true for 3-channel and 4-channel memory configurations, such as Intel X58 and X79 based high-end desktop systems and also for NUMA-enabled multi-socket systems, such as 2- and 4-way AMD Opteron and Intel Xeon based servers and workstations. With the new benchmarks you will however get considerably higher scores, much closer to the theoretical memory bandwidth available. On modern multi-core processors, using the old single-threaded benchmarks you couldn't see the actual memory bandwidth, but only the memory bandwidth available for single-threaded applications. The new bandwidth (read, write copy) benchmarks now use multiple threads to squeeze out every last bit of performance from the caches and the memory modules. On Haswell AIDA64 v3.00 will utilize all new instruction set extensions, so the benchmarks and the System Stability Test will also use the appropriate AVX2, FMA and BMI2 instructions.īut more importantly, we've replaced the outdated set of memory benchmarks with brand new ones. It will feature the usual improvements to support the latest and greatest hardware technologies, such as GPU details for AMD Radeon HD 7990 "Malta" and nVIDIA GeForce 700 Series, and optimized benchmarks for AMD Kabini/Temash and Intel Haswell.
We're rolling out a new major update to AIDA64 on June 03, 2013.
