CPU Speed Pro has completed over one million individual CPU Benchmark tests and still counting!

Each week CPU Speed Pro benchmarks thousands of CPUs to bring you the most accurate Intel and AMD CPU benchmark scores. Download CPU Speed Pro today and benchmark your Processor

Our benchmark charts compare Intel vs AMD CPU speeds and to help determine the speeds of all the different processor types. We include desktop, laptop, netbook and server CPUs, Intel Atom processors, the latest I7 core, Intel Xeon and AMD Opteron processors.

CPU Speed Pro has tested overclocked CPUs, high end processors, server hardware, mid-range CPUs, Intel atom netbook CPUs, full Netbook CPU shootouts - AMD vs. Intel vs. VIA and more. Intel's Atom CPU is is facing competition from ARM processors, and the recently launched AMD Athlon Neo.

Benchmark test description, and how your CPU speed compares with other same-specification CPUs

CPU Benchmark results are submitted to the benchmark result section of the CPU Speed Pro web site. CPU Speed Pro powers a range of CPU functions and conducts different tests which are then compared against equivalent CPUs to determine a rating for the system.

To maintain absolute accuracy, CPU Speed runs each CPU test on all available CPUs. Further, the CPU test is also run on every logical CPU (hyper-thread), physical CPU core (dual core) or physical CPU package (multiple CPU chips).
