Performance Testing

General Performance Testing

All performance testing was done with the i7-8700K and GTX 1070 at default clock speed. CPU was left with Speed Step and Turbo Boost enabled. Games where ran at a resolution of 1920 x 1080 and higher settings enabled as noted.

PCMark 10

PCMark 10 is the complete benchmark for the modern office. It is the ideal test for organizations that are evaluating PCs for a workforce with a range of performance needs. The tests in this benchmark cover a wide range of activities from everyday productivity tasks to demanding work with digital media content.

PCMark 10 uses a modular approach to build relevant benchmark tests around common end-user scenarios. A Test Group is a collection of workloads that share a common theme or purpose. There are four test groups in PCMark 10, we use three of them.

Essentials: covers the common, everyday ways that people use a PC. The workloads include Web Browsing, Video Conferencing, and App Start-up time.

 Productivity: measures system performance with everyday office applications. This test group includes Spreadsheets and Writing workloads.

Digital Content Creation: This test group's workload reflects the demands of working with digital content and media. The tests include Photo Editing, Video Editing, and Rendering and Visualization.

Intel Core i7-9800X

The comparatively lower clock speeds put the i7-9800X a little bit behind the mainstream-oriented i9-9900K, but that IS an i9 after all.

 

WebXPRT 2015

WebXPRT 2013 uses scenarios created to mirror the tasks you do every day to compare the performance of almost any Web-enabled device. It contains four HTML5- and JavaScript-based workloads: Photo Effects, Face Detect, Stocks Dashboard, and Offline Notes.  WebXPRT is run with the latest stable release version of Google Chrome browser, in this case, Version 61.

Intel Core i7-9800X

Performance here comes in ahead of all of our other SkyLake based CPUs with the exception of the i7-7820X which beats the 9800X by a decent amount.

 

CPU Performance Testing

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.”

 Intel Core i7-9800X

The abilities of Turbo Boost 3.0 here are quite apparent, the i7-9800X just flies with only one thread in use and scores just over 7 minutes and 12 seconds, one of our best times.

 

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.”

Intel Core i7-9800X

Interestingly, the i7-9800X does really great in this test, only falling to raw core count under the i9-7960X,

 

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 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."

Intel Core i7-9800X

With all cores in play, the i7-9800X does great here, narrowly missing first place for our 8-core chips.

 

Y-Cruncher

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 in compatible 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.

Intel Core i7-9800X

The ability of all Skylake-X chips to take advantage of AVX512 instructions and coupled with a respectable clock speed, the i7-9800X solves for 1 Billion digits of pie the fastest of all of our chips here in both single and multi-threaded modes.

 

7-Zip

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 reach 100, the score is taken

Intel Core i7-9800X

We see a very significant jump over older 8 and even 10-core CPU’s and quad-channel memory even gives the 9800X an edge over the mainstream 9900K.

 

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.

Intel Core i7-9800X

With everything equal here, the 9900K manages to just barely hold an edge over the 9800X thanks to its faster stock clock speeds.

 

Memory Performance Testing

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.

Intel Core i7-9800X

The i7-9800X manages over 87GB/s on reads with a bit underwhelming 64.5GB/s on writes but recovers on copy functions to a little under 78GB/s.

Intel Core i7-9800X

The 9800X is our lowest latency Skylake-X CPU tested so far with a latency of 67.2ns

Intel Core i7-9800X

No matter which category you sort by, the i7-9800X does well with significant L1 cache bandwidth.

Intel Core i7-9800X

The 9800X has a little higher copy bandwidth for the L2 cache than the outgoing 7820X but read and writes are reasonably close.

Intel Core i7-9800X

L3 cache bandwidth isn’t quite as impressive, coming in at 126GB/s and 102GB/s for reads and writes respectively.

 

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.”

Intel Core i7-9800X

The i7-9800X isn’t anything if it isn’t strong in memory performance, and Passmark confirms this with our best score yet.

 

SiSoft Sandra – Memory Bandwidth.

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

Intel Core i7-9800X

SiSoft shows very high memory bandwidth in its testing, easily clearing the 63GB/s mark in everything, our fastest yet.

 

Game Testing

3DMark – Fire Strike

"Fire Strike is a showcase DirectX 11 benchmark designed for today's high-performance gaming PCs. It is our most ambitious and technical benchmark ever, featuring real-time graphics rendered with detail and complexity far beyond what is found in other benchmarks and games today"

Intel Core i7-9800X

The 9800X provides solid gaming performance and manages 20,274 points in the CPU only Physics test.

 

3DMark – Time Spy

"3Dmark Time Spy is a new DirectX 12 benchmark test for Windows 10 gaming PCs. Time Spay is one of the first DirectX 12 apps to be built “the right way” from the ground up to fully realize the performance gains that the new API offers. With DirectX 12 engine, which supports new API features like asynchronous compute, explicit multi-adapter, and multi-threading, Time Spy is the ideal test for benchmarking the latest graphics cards.”

Intel Core i7-9800X

Timespy doesn’t show a huge difference between CPU scores on all of our 8-core CPUs because, at 1440p in the base test, we are leaning most heavily on the GPU.

 

Grand Theft Auto: V

"When a young street hustler, a retired bank robber, and a terrifying psychopath find themselves entangled with some of the most frightening and deranged elements of the criminal underworld, the U.S. government and the entertainment industry, they must pull off a series of dangerous heists to survive in a ruthless city in which they can trust nobody, least of all each other.”

Intel Core i7-9800X

For ease of testing, we slotted in an older GTX 1070 for this testing to keep our comparison. This and the next game will be tested with this instead of our more recent standard RTX2080. At 1080P and less than maximum settings, this game is very CPU bound by the game engine. The 9800X slides in at 175FPS average.

 

Metro: Last Light

"It Is the Year 2034. Beneath the ruins of post-apocalyptic Moscow, in the tunnels of the Metro, the remnants of mankind are besieged by deadly threats from outside – and within. Mutants stalk the catacombs beneath the desolate surface, and hunt amidst the poisoned skies above."

Developed by 4A Games and published by Deepsilver, Metro: Last Light uses the 4A game engine. At its highest settings, the 4A game engine is capable of bringing all but the most extreme gaming systems to their knees.

Intel Core i7-9800X

Metro fares pretty well with a slight increase over the older 7820X, but that’s still not enough to catch the 9900K.
