The Intel Core i9-7900X 10-core Skylake-X Processor Review
SYSmark, WebXPRT, 7-zip
For this review, every single benchmark and test scenario we use has been updated or removed, including a couple of new entries. We are using the most up to date versions of each software as of last week, to make sure we account for any changes or architectural changes that have occurred. Here is the new suite, in alphabetical order.
- 7-zip Compression
- Audacity MP3 Encode
- Cinebench R15
- Euler 3D
- SiSoft Sandra
- SYSmark 2014 SE
- X264 Encode

SYSmark 2014 SE
SYSmark® 2014 SE (Second Edition) is an application-based benchmark that reflects usage patterns of business users in the areas of Office Productivity, Data/Financial Analysis and Media Creation. Joining these in SYSmark 2014 SE is a new Responsiveness scenario which models ‘pain points’ in the user experience when performing common activities. SYSmark 2014 SE features the most popular applications from each of their respective fields.
This set of real-world tests form SYSmark is our first indication that something good is happening with the Core i9-7900X. The Office Productivity score of the new CPU is actually slightly ahead of the Core i7-7700K and it is 16% higher than the Core i7-6950X. The higher base and Turbo clocks of the new SKL-X parts looks to have a significant impact on single threaded workload performance. Total power consumption during the test on the 7900X is lower than the 6950X, despite the power draw on the Skylake-X platform being higher (as we’ll show later), indicate that work was done faster, allowing the CPU to get to idle power more quickly.
It runs these four tests seven times each:
- Photo Enhancement: Measures the time to apply three effects (Sharpen, Emboss, and Glow) to two photos each, a set of six photos total.
- Organize Album: Measures the time it takes to check for human faces in a set of five photos.
- Stocks Option Pricing: Measures the time to calculate financial indicators of a stock based on historical data and display the result in a dashboard.
- Local Notes: Measures the time to store notes securely in the browser's local storage and display recent entries.
- Sales Graphs: Measures the time to calculate and display multiple views of sales data.
- Explore DNA Sequencing: Measures the time it takes to filter eight DNA sequences for specific characteristics.
The Core i9-7900X is 19% faster than the Core i7-6950X, although it still lags behind the performance of the 7700K. This indicates some additional advantage to the faster SpeedShift implementation.
The Core i9-7900X pulls in the fastest 7zip compression numbers of any processor we tested through 8-threads.
