CPU-Z is a freeware that gathers information on some of the main devices of your system:
- Processor name and number, codename, process, package, cache levels.
- Mainboard and chipset.
- Memory type, size, timings, and module specifications (SPD).
- Real-time measurement of each core’s internal frequency, memory frequency.
AIDA64 Engineer Edition
“AIDA64 Engineer has a hardware detection engine unrivaled in its class. It provides detailed information about installed software and offers diagnostic functions and support for overclocking. As it is monitoring sensors in real time, it can gather accurate voltage, temperature and fan speed readings, while its diagnostic functions help detect and prevent hardware issues. It also offers a couple of benchmarks for measuring the performance of individual hardware components or the whole system. It is compatible with all 32-bit and 64-bit Windows editions, including Windows 10 and Windows Server 2016.”
Since bandwidth is mostly a function of raw speed, the 3866MHz Viper Steel does quite well here and places about exactly where we expect it to.
Latency comes in a bit faster than we expected at 45.5ns.
Passmark Performance Test – Memory Mark – Threaded
“Fast, easy to use, PC speed testing and benchmarking. PassMark PerformanceTest ™ allows you to objectively benchmark a PC using a variety of different speed tests and compare the results to other computers.”
Passmark reacts quite well to the very fast XMP speed and gives us a great score of just over 44k, second only to the 4133MHz kit above it.
“SiSoftware Sandra provides a robust package of diagnostic tools for testing your system and teasing out its problems–or potential headaches.”
SiSoft works a little differently, and tests more real-world scenarios, so the C18 timings hurt a little here, but we still manage over 34GB/s in all three segments.
Super PI Modded 1.5
“In August 1995, the calculation of pi up to 4,294,960,000 decimal digits was succeeded by using a supercomputer at the University of Tokyo. The program was written by D.Takahashi in collaboration with Dr.Y.Kanada at the computer center. This record should be the current world record. (Details are shown in the windows help.) This record-breaking program was ported to personal computer environments such as Windows NT and Windows 95. In order to calculate 33.55 million digits, it takes 3 days with a Pentium 90 MHz, 40 MB main memory and 340 MB available storage.”
The faster speeds help push a single thread along to a time of 7 minutes and eleven seconds.
The benchmark shows a rating of MIPS (million instructions per second). The rating value is calculated from the measured speed, and it is normalized with results of Intel Core 2 CPU with multi-threading option switched off. So if you have modern CPU from Intel or AMD, rating values in single-thread mode must be close to real CPU frequency. There are two tests, compression with LZMA method and decompression with LZMA method. Once the total passes reach 20 or more, the score is taken.
7-zip is able to take full advantage of the increased bandwidth and comes in just over 53,000 MIPS.
