Intel Core i7 7740X CPU Review

General Performance and CPU Performance Results

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.

General Performance Results

PCMark 8

“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.”

With so little difference between Intel’s Core i7 7700K and Core i7 7740X specifications, we were not expecting much of a difference in performance. In PCMark 8, the Core i7 7740X just edges out the Core i7 7700K.

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.”

The roles reversed in Super Pi with the Core i7 7740X falling just behind the Core i7 7700K.

CPU Performance Results

Fritz Chess

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.

The results from Fritz Chess are more in line with what we saw in PCMark 8.

CINEBENCH R15

“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.”

Cinebench is much in the same.

7-Zip

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.

 

We see the two 4-core i7s switch spots again in 7-Zip.

Handbrake

“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, 1920×858, ~17.1 Mbps, 24fps, H.264, .mp4 video file. Transcoding is done using Intel Quick Sync.

…and again in Handbrake. It looks like the two processors are similar enough that there’s almost no performance difference between them.

Memory Performance Results

AIDA64 Engineer Edition

“FinalWire Ltd. today announced the immediate availability of AIDA64 Extreme Edition 1.50 software, a streamlined diagnostic and benchmarking tool for home users; and the immediate availability of AIDA64 Business Edition 1.50 software, an essential network management solution for small and medium scale enterprises. The new AIDA64 update implements AVX-optimized benchmarks for the upcoming Intel Sandy Bridge processors, adds a brand new video encoding benchmark, and supports the latest AMD and nVIDIA graphics processors.”

The Kaby Lake responds well to increases in memory speed.

Much like our other testing, cache performance also goes back and forth between the two i7s.

Passmark Performance Test 8 – Memory

 

Passmark confirms what we already saw with AIDA64.

SiSoft Sandra

“SiSoftware Sandra provides a robust package of diagnostic tools for testing your system and teasing out its problems–or potential headaches.”

The Core i7 7740X leads the two channel memory results in Sandra.
