The AMD Ryzen Threadripper Box
The AMD Ryzen Threadripper comes in an awesome box. Check it out!
Multithreaded CPU Performance
Here is a summary of the results, using the Intel Core i9-7900X as the baseline (100%) :
|Benchmark||Intel Core i9-7900X||AMD Ryzen Threadripper 1920X||AMD Ryzen Threadripper 1950X|
|POV-Ray 3.7||100%||+ 6.1%||+ 30.8%|
|Adobe Premiere Pro CC 2017||100%||– 4.9%||+ 16.7%|
|HandBrake 1.0.7||100%||+ 5.1%||+ 21.0%|
|7-Zip 16.0.2||100%||+ 3.5%||+ 26.9%|
|VeraCrypt 1.2.1||100%||+ 18.6%||+ 55.1%|
|Corona Photorealism 1.3||100%||+ 1.1%||+ 26.8%|
1440p Gaming Performance
And here are 1440p gaming performance results on the two AMD Ryzen Threadripper processors, using the NVIDIA GeForce GTX 1080 Ti.
Here is a quick comparison of the results, using the Threadripper 1920X (Lowest Price) as the baseline (100%) :
|Benchmark||AMD Ryzen Threadripper 1920X||AMD Ryzen Threadripper 1950X|
|Rise of the Tomb Raider||100%||+ 0.7%|
|Ashes of the Singularity||100%||+ 5.3%|
|Deus Ex: Mankind Divided||100%||+ 2.9%|
|Battlefield 1||100%||+ 1.7%|
The Threadripper Game Mode
Games are mostly optimised for quad-core processors… and rarely make use of octa-core processors. In fact, having even more cores can result in poorer performance due to poor thread scheduling. In some cases, the game may not even run at all.
To avoid those problems, AMD developer the Threadripper Game Mode. You can switch from the default “Creator Mode” to the “Game Mode” in the AMD Ryzen Master utility. Switching to Game Mode changes the Threadripper processor in two ways :
- It temporarily disables half the CPU cores, turning the Threadripper 1950X (Lowest Price) into an 8C 16T processor like the AMD Ryzen 1800X, and the Threadripper 1920X (Lowest Price) into an 6C 12T processor like the AMD Ryzen 1600X.
- It tells the operating system to use a Local Mode (NUMA) memory, which keeps the game and its memory footprint inside one CPU die and the locally-connected DRAM memory. This minimises several key latency points in the system, which will improve gaming performance.
Once you are done playing your game, you can switch back to Creator Mode to make full use of all of the Threadripper’s cores.
Let’s take a look at the performance difference between the Creator Mode and the Game Mode.
As you can see, the Game Mode improves the AMD Ryzen Threadripper 1950X’s gaming performance by 10% to 38%. It’s likely that disabling half the cores also allow the Threadripper to clock them higher, as there is now a much higher thermal headroom.
