Written by Alexander J. Lee “From a high-school project that went a little too far…” y-cruncher, (y for gamma) is a number-crunching program that can compute various mathematical constants.
It was originally a small program specialized for computing the Euler-Mascheroni Constant. (Which uses gamma as its symbol, hence the name). It has since gained the ability to compute other constants.
It is the first of its kind that is multi-threaded and scalable to multi-core systems. Ever since its launch in 2009, it has become a common benchmarking and stress-testing application for overclockers and hardware enthusiasts.
We tested using the built-in benchmarks to compute Pi to 1 Billion Digits in both single and multi-threaded mode and recorded the Total Computation time at the end of the run. Y-Cruncher is also able to take advantage of AVX512 instructions incompatible CPU’s. Due to the thermal load of running Intense AVX workloads, Intel has implemented and AVX offset clock that may scale the CPU’s clock speed back, even below stock speeds when running intense AVX loads. For this reason, we note the CPU’s clock speed in both single and multi-threaded test modes.
Interestingly, the 8086K comes in a shade behind the 8700K on both multi-core and single core testing in the AVX based y-cruncher.
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 within 3 days with a Pentium 90 MHz, 40 MB main memory and 340 MB available storage.”
In the single threaded Super Pi, the 8086K owns the benchmark, coming in a full 5 seconds faster than the previous best to top the chart.
SiSoft Sandra – Cryptographic Bandwidth
“SiSoftware Sandra provides a robust package of diagnostic tools for testing your system and teasing out its problems–or potential headaches.”
Scoring 12.2GB/s in Sisoft Sandra’s Cryptographic bandwidth test places the 8086K just behind its 8700K counterpart.
“CINEBENCH is a real-world cross platform test suite that evaluates your computer’s performance capabilities. CINEBENCH is based on MAXON’s award-winning animation software CINEMA 4D, which is used extensively by studios and production houses worldwide for 3D content creation. MAXON software has been used in blockbuster movies such as Iron Man 3, Oblivion, Life of Pi or Prometheus and much more.
CINEBENCH is the perfect tool to compare CPU and graphics performance across various systems and platforms (Windows and OS X). And best of all: It’s completely free.”
The very very close race here has to go to the 8086K but by less than 1% over the 8700K.
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 100, the score is taken
There is a 2500 point spread between the commemorative CPU and its counterpart here.
Black Hole 4.2
Let the beast run and benchmark your system in three different tests (Multithreaded, Single-threaded & 4-Threaded) that will test your CPU to the very limit, and score you among hundreds of other systems that have tested.
Multithreaded will test your CPU’s efficiency of running more than one thread without major system lag. The higher you score on this one, the more threads your CPU can handle with a comfortable speed. High multithreaded scores generally mean you can render things faster.
4-Threaded tests your CPU’s performance in games since most games currently run on 4 threads.
Single-threaded evaluates how fast the CPU can handle a single, dedicated thread for processing.
Black Hole Benchmark certainly likes the faster speeds at lower thread counts as is evident by the single threaded score.
