Cinebench R15 (Single-Core & Multi-Core) :

Cinebench R15 is the successor Cinebench. It evaluates the CPU performance by rendering a 3D scene. The faster the rendering of the scene is created, the more powerful the PC is, with a high number of points.

Cinebench R20 (Single-Core & Multi-Core) :

Cinebench R20 is a benchmark tool which allows to evaluate the hardware capacities. such as computer, a server.

PassMark (Single-Core & Multi-Core) :

PassMark is a benchmark software which measures the performance of the CPU. The higher the score is, the higher is the device capacity.

Geekbench 4 (Single-Core & Multi-Core):

Geekbench 4 is a complete benchmark platform with several types of tests, including data compression, images, photo editing, memory testing etc. This allows us to better visualize the respective power of these devices.

On Windows 64-bit
On Linux 64-bit

Which One To Buy ?

Firstly,you should think about what type of work you are going to do on your PC. Find out what type of software you are going to use frequently on your PC. If you are going to work on high-level projects, playing high-level games, or going to run heavy software then you can go for AMD Ryzen Threadripper 3990x. But remember that it’s a very costly processor compare to Intel.

So I suggest if you are not going to work on such high-level software, games or budget limitation and looking for normal use then you can go with Intel Core i9 9900k.

Expert Review of AMD Ryzen Threadripper 3990x :

AMD’s decision to pair 64 cores and 128 threads with higher boost frequencies pays big dividends in VFX, 3D animation, and ray tracing workloads with more performance than you would expect from any comparable workstation-class solution, not to mention even some dual-socket servers.


There are definitely areas where it doesn’t just represent poor value, but is actually slower than cheaper CPUs.


Overall an incredible product from AMD that is not only exciting for professionals today, but it paves the way for more affordable core-heavy desktop parts in the near future.


Expert Review of Intel Core i9 9900k :

Intel might be late to the game with its first mainstream octa-core processor, but the Intel Core i9-9900K is an impressive debut


Intel heralded the i9-9900K as the ‘the world’s best gaming desktop processor’ during launch.

Trusted Reviews

Normally I’d say that the Core i9 9900K is the new king of desktop processors. However, price versus performance wise the Ryzen 2700X does hold ground
