So, to have some elements of comparison, here are some scores with CPU-Z 1.78 and CPU-Z 1.79.Īnd of course, this CPU-Z benchmark was an opportunity to check the performances of the R圜PU 😉 1 – CPU-Z 1.78 CPU Benchmark Single Thread 2142 – AMD Ry(8 cores / 16 threads, 3.0GHZ base, 3.7GHz boost)ġ796 – Intel Core i7 7700HQ (4 cores / 8 threads, 3.8GHz boost)ġ790 – Intel Core i5 6500 (4 cores / 4 threads, 3.2GHz)ġ774 – Intel Core i5 6600K (4 cores / 4 threads, 3.5GHz)ġ723 – Intel Core i5 4670K (4 cores / 4 threads, 3.8GHz boost)ġ669 – Intel Core i7 3770K (4 cores / 8 threads, 3.5GHz)ġ529 – Intel Core i7 6500U (2 cores / 4 threads, 2.5GHz)ġ249 – Intel Core i5 2320 (4 cores / 4 threads, 3.5GHz)Ħ84 – AMD FX 6100 (6 cores / 6 threads, 3.3GHz) More information about the new CPU benchmark in CPU-Z 1.79 can be found in this article: CPU-Z 1.79 : new benchmark, new scores. No special instruction set is used, but the 圆4 version uses scalar SSE/SSE2 instructions to achieve floating point operations, whereas the 32-bit version keeps using the legacy x87 instructions, resulting in almost half of the 圆4 performance. The code is written in C++, and compiled with Visual C++ 2008. The new benchmark computes a 2-dimensional noise function, that could typically be used in a game to generate a procedural map. When Ryzen was released, we found out that their ALUs executed this unexpected sequence in a much more efficient way, leading to results that mismatch the average performance of that new architecture. These operations added a noticeable but similar delay in all existing microarchitectures at the time the previous benchmark was developed. After a deep investigation, we found out that the code of the benchmark felt into a special case on Ryzen microarchitecture because of an unexpected sequence of integer instructions. Here is the main reason that led to an update of the CPU benchmark:Īlmost two years later, Ryzen was introduced, and scored – core for core and clock for clock – almost 30% higher than Intel Skylake.
In the latest CPU-Z 1.79, the CPU benchmark has been updated to better handle new multi-core CPUs like AMD Ryzen, and scores have no longer relation with previous versions of CPU-Z. The CPU benchmark performs two quick tests: a single threaded test and a multi threaded test. This CPU benchmark is available since CPU-Z 1.73 (released in 2015).
CPU-Z, the popular CPU information utility, comes with a CPU benchmark module.
