System Benchmarks

In the System and Gaming Benchmarks sections, we reveal the results from a number of benchmarks run with the Core i7-7740X and Core i9-7900X on STRIX X299-E Gaming motherboard. These tests were run at default clocks, with the best automatic overclock, and using our own manual overclock. This will illustrate how much performance can be achieved with this motherboard in stock and overclocked form. For a thorough comparison of the Core i7-7740K versus a number of different CPUs have a look at our “The Intel Kaby Lake-X i7-7740X Review” article.

SuperPi Mod v1.9 WP

When running the SuperPI 32MB benchmark, we are calculating Pi to 32 million digits and timing the process. Obviously more CPU power helps in this intense calculation, but the memory sub-system also plays an important role, as does the operating system. We are running one instance of SuperPi Mod v1.9 WP. This is therefore a single-thread workload.


wPRIME 2.10

wPrime is a leading multithreaded benchmark for x86 processors that tests your processor performance by calculating square roots with a recursive call of Newton’s method for estimating functions, with f(x)=x2-k, where k is the number we’re sqrting, until Sgn(f(x)/f'(x)) does not equal that of the previous iteration, starting with an estimation of k/2. It then uses an iterative calling of the estimation method a set amount of times to increase the accuracy of the results. It then confirms that n(k)2=k to ensure the calculation was correct. It repeats this for all numbers from 1 to the requested maximum. This is a highly multi-threaded workload.


Cinebench R15

Cinebench R15 64-bit
Test1: CPU Image Render
Comparison: Generated Score

The latest benchmark from MAXON, Cinebench R15 makes use of all your system’s processing power to render a photorealistic 3D scene using various different algorithms to stress all available processor cores. The test scene contains approximately 2,000 objects containing more than 300,000 total polygons and uses sharp and blurred reflections, area lights and shadows, procedural shaders, antialiasing, and much more. This particular benchmarking can measure systems with up to 64 processor threads. The result is given in points (pts). The higher the number, the faster your processor.


WinRAR x64

WinRAR x64 5.40
Test: Built-in benchmark, processing 1000MB of data.
Comparison: Time to Finish

One of the most popular file archival and compression utilities, WinRAR’s built-in benchmark is a great way of measuring a processor’s compression and decompression performance. Since it is a memory bandwidth intensive workload it is also useful in evaluating the efficiency of a system’s memory subsystem.



FAHBench 1.2.0
Test: OpenCL on CPU
Comparison: Generated Score

FAHBench is the official FAH benchmark that measures the compute performance of CPUs and GPUs. It can test both OpenCL and CUDA code, using either single or double precision, and implicit or explicit modeling. The single precision implicit model most closely relates to current folding performance.

Since Intel’s OpenCL drivers don’t yet support Skylake-X processors, we had to use AMD’s APP SDK 3.0 tool, which had no such limitations.

HEVC Decode Benchmark v1.61

HEVC Decode Benchmark (Cobra) v1.61
Test: Frame rates at various resolution, focusing on the top quality 25Mbps bitrate results.
Comparison: FPS (Frames per Second)

The HEVC Decode Benchmark measures a system’s HEVC video decoding performance at various bitrates and resolutions. HEVC, also known as H.265, is the successor to the H.264/MPEG-4 AVC (Advanced Video Coding) standard and it is very computationally intensive if not hardware accelerated. This decode test is done entirely on the CPU.


LuxMark v3.1

Test: OpenCL CPU Mode benchmark of the LuxBall HDR scene.
Comparison: Generated Score

LuxMark is a OpenCL benchmarking tool that utilizes the LuxRender 3D rendering engine. Since it OpenCL based, this benchmark can be used to test OpenCL rendering performance on both CPUs and GPUs, and it can put a significant load on the system due to its highly parallelized code.

Once again, since Intel’s OpenCL drivers don’t yet support Skylake-X processors, we had to use AMD’s APP SDK 3.0 tool, which had no such limitations.

PCMark 8

PCMark 8 is the latest iteration of Futuremark’s system benchmark franchise. It generates an overall score based upon system performance with all components being stressed in one way or another. The result is posted as a generalized score. In this case, we tested with both the standard Conventional benchmark and the Accelerated benchmark, which automatically chooses the optimal device on which to perform OpenCL acceleration. 

AIDA64 Memory Benchmark

AIDA64 Extreme Edition is a diagnostic and benchmarking software suite for home users that provides a wide range of features to assist in overclocking, hardware error diagnosis, stress testing, and sensor monitoring. It has unique capabilities to assess the performance of the processor, system memory, and disk drives.

The benchmarks used in this review are the memory bandwidth and latency benchmarks. Memory bandwidth benchmarks (Memory Read, Memory Write, Memory Copy) measure the maximum achievable memory data transfer bandwidth. The code behind these benchmark methods are written in Assembly and they are extremely optimized for every popular AMD, Intel and VIA processor core variants by utilizing the appropriate x86/x64, x87, MMX, MMX+, 3DNow!, SSE, SSE2, SSE4.1, AVX, and AVX2 instruction set extension.
The Memory Latency benchmark measures the typical delay when the CPU reads data from system memory. Memory latency time means the penalty measured from the issuing of the read command until the data arrives to the integer registers of the CPU.
