General Performance and CPU Performance
We were rather constrained for time. We have included as many comparison processors as possible. In some cases, there wasn’t enough time to test every possible processor at our disposal, so we included the most pertinent for comparison.
"Use the PCMark 8 Storage benchmark to test the performance of SSDs, HDDs and hybrid drives with traces recorded from Adobe Creative Suite, Microsoft Office and a selection of popular games. You can test the system drive or any other recognized storage device, including local external drives. Unlike synthetic storage tests, the PCMark 8 Storage benchmark highlights real-world performance differences between storage devices."
The PCMark 8 Home Conventional and Creative tests prefer speed over a higher number of cores. The extra 200 MHz base clock and 300 Mhz turbo clock gives the Core i7 7700K the clear advantage here. The Core i7 7700K is only slightly behind the Core i7 5820K in the Work Conventional tests.
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 environment 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.”
Super Pi showed a similar result to PC Mark and more than likely for the same reason. The AMD processors don’t far well here and Intel clearly dominates with the Core i7 7700K taking the lead again.
Fritz Chess is a benchmark in which a fictitious game of chess is played. As each move has to be calculated by the computer, it is an excellent test of CPU muscle.
Fritz Chess runs on a maximum of 4 cores. The Core i7 7700K takes the lead here even besting the 6 core Core i7 5820K.
"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 many 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 Core i7 7700K has about a 4% lead over the previous Core i7 6700K. Still, more cores allows it to fall behind the Core i7 5820K
This form allows you to measure the performance of your computer. The benchmark shows a rating in 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 reaches 100, the score is taken.
Here we see some really nice gains from the Core i7 7700K.
“HandBrake is a tool for converting video from nearly any format to a selection of modern, widely supported codecs.”
The workload video file is a ~6.27 GB, 3840 x 1714, 73.4 Mbps, 24fps, H.264, .mov video file that is transcoded to a ~1480 MB, 1920x858, ~17.1 Mbps, 24fps, H.264, .mp4 video file. Transcoding is done using Intel Quick Sync.
Handbrake shows similar gains like we saw with 7-Zip, but the Core i7 7700K is able to easily out-muster every other processor.
