These are people who build high-performance desktop computers, overclocking their CPU. Passmark can be considered the current reigning champion of CPU benchmarking for tech-savvy system builders. Also, the entire program is self-contained, meaning it will compile without system specific libraries. ARM)ĭhrystone is unique, in that its binary footprint is small enough to benchmark embedded CPU’s found powering smaller devices. Performing synthetic benchmarks to compare different system architectures (for example Intel x86 vs.Giving a great comparison of compiler performance.Benchmarking embedded CPU’s in small devices.Advantages of Dhrystone CPU benchmarking: Its main purpose in today’s world is testing embedded CPU’s like those found in machinery and other equipment. Also system operations such as memory speed and Front-side Bus architecture not represented in bench tests.īut this is not what Dhrystone is used for any longer. The above shortcomings amount to benchmarks not showing results from real-world operations, architecture deficiencies not being exposed (as in the previous Intel to AMD architecture benchmark comparison). The entire application is small and will fit into a modern CPU’s EX Core cache. No floating point math tests, so FLU is left untested.String sorting is done with aligned strings.Disadvantages of Dhrystone CPU benchmarking: As it suffers several flaws that can cause misrepresented benchmarks. The original Dhrystone benchmark was coded in Ada.ĭhrystone, though popular at the time is not really used much in today’s world. This was released in the 1980’s then gained popularity when it was ported for Unix in C. While not even touching on better processing efficiency found in business CPU architecture.ĭhrystone is included for historical significance. So when we see CPU architectures like the XEON being rated very close to (and greatly exceeding in some operations) performance in terms of office-user tasks, in say a benchmark score from Passmark: that is saying a lot. Recovery from a blue screen for a server or a high-end workstation can result in loss of up to 8 hours in work or more in lost revenue.Similar tasks to consumer computing are being performed simultaneously, non-stop.With this in mind let’s look at business class computing: Due to the error correction checking, a hit will be taken on overall CPU execution time. Error Correcting Code in memory will not only assist in preventing crashes but also protect against hardware failure (as noted by a Microsoft paper entitled: Cycles, Cells, and Platters: An Empirical Analysis of Hardware Failures on a Million Consumer PCs). This is true for any operation from calculating multiple floating point numbers to encrypting multiple files.Īlso worth a note that business class CPU’s such as a Xeon make use of ECC memory. Unless the distributed workers are magnitudes slower, like a 4GHZ clock rate versus four 80486 CPU’s. Instead of measuring how well a CPU will process data in a 4-month period, tests are done in short bursts to simulate use of an end-user (versus a server).įrames Per Second Benchmarks Are Only Usefulįor Gaming. The second thing we must note is most CPU benchmarking tools (all covered in this guide) will evaluate a CPU based on consumer computing and not server demands. Not really how well the CPU is performing as an individual component. These will really measure how well the CPU keeps up with offloaded processing of a high-end GPU. Video gaming, when rated in frames per second (FPS) is highly dependent on a high-performance video card. The first thing we want to avoid are benchmarks that rate a complete system for gaming. Only then is it possible to accurately gauge the performance of a CPU with benchmarking utilities. This way benchmarks can be compared to past contributors. It is also important to use a widely known CPU benchmarking tools. However, time should be taken to understand what is being evaluated in a benchmark. Most CPU Benchmarking tools are accurate in what they do.
