Amd Ryzen 9 3900x Vs Intel Core I9 9900k Which High End Cpu To Buy

In this post, nosotros compare Intel and AMD’s flagship desktop processors, the Ryzen 9 3900X and the Cadre i9-9900K and see which one is faster Although technically the AMD Ryzen nine 3950X is the fastest consumer CPU, we won’t be because it as it mostly squares off in the HEDT space, against the Cascade Lake-X parts.

We volition be putting AMD and Intel’s fastest desktop chips through their paces and analyze how they perform beyond a variety of workloads from gaming to content cosmos every bit well twenty-four hours-to-mean solar day tasks like file-compression and video encoding.

AMD Ryzen nine 3900X vs Intel Core i9-9900K: Specifications

Ryzen 9 3900X Core i9-9900K
Cores/Threads 12/24 8/xvi
Base Clock 3.8GHz iii.6GHz
Boost Clock 4.6GHz 5GHz
L2 Enshroud 6MB 2MB
L3 Cache 64MB 12MB
TDP 105W 95W
Price $400 $480

On paper, the Ryzen 9 has the Core i9-9900K beat on all fronts except the heave clock. Looking at the TDP, it may seem similar the latter is more power-efficient but that’s far from the truth. The 9900K draws nearly 200W under load while the 3900X doesn’t cross the 120W marking in near cases. Furthermore, the pricing makes information technology fifty-fifty harder to recommend the Core i9. Recently, AMD’s Ryzen 3000 CPUs accept seen some steep price drops, bringing the Ryzen ix down to $400 (from $500). The 9900K still retails for a hefty $550 ($480 on Microcenter). You lot can snag the KF variant for less than $500 if you plan on using a discrete GPU.

AMD Ryzen nine 3900X vs Intel Core i9-9900K: Gaming Performance

In gaming, the Intel Core i9-9900K is faster by effectually 10-15% on boilerplate. Although certain games like Assassins’ Creed and Ashes of the Singularity (not included above) are known favor the college cadre count of the Ryzen 9, they’re part of the minority. The conclusion here is that in terms of gaming performance, Intel all the same has a clear lead in the ultra-high-end segment.

Content Creation

Surprisingly in the unmarried-threaded Cinebench R20 exam, the Ryzen nine 3900X manages to border past the Core i9-9900K despite having a lower boost clock. This means that the arrears in gaming may exist due to the latency induced past the Infinity Material, rather than the IPC.

The multi-threaded benchmark goes as expected. The 3900X and its 24 threads impose a heavy lead over the 9900K. The former is nearly 50% faster than the Coffee Lake flagship. For the sake of comparison, the 1st Gen Threadripper with its 32 threads scores but above 6,500 points. That’s notably lesser than the 3rd Gen Ryzen 9 3900X. AMD really has come a long mode in the last 2 years.

The delta only widens in IndigoBench, with the Ryzen nine increasing its lead over the 9900K to a staggering 75%. For content creators and professionals, the 3rd Gen Ryzen lineup is a dream come true. A $400 chip performing on par with a $1,000 part is null curt of phenomenal.

Encoding, Browsing, and Compression

Compression/decompression, spider web-browsing, and encoding applications are used on a large calibration past simply near anybody. Nosotros consider these as a measure of day-to-mean solar day or real-globe performance. In 7-zip (both pinch and decompression), the Ryzen 9 squishes the Core i9 by a fatty margin. The deltas in Handbrake x264 and Kraken (browsing) are less pronounced but even so, mark a resounding victory for the Ryzen 9.


Overall, the Ryzen 9 3900X is the undoubted functioning king. Offering 90% of the gaming performance every bit the Cadre i9-9900K and being more than 50% faster in everything else, the 3900X is the clear winner here. However, which chip you should opt for largely depends on your workloads. If you are edifice a gaming PC that will be used exclusively for loftier frame-rate gaming, then the Core i9 is a no-brainer. However, if you lot’re a content creator or your workloads are more versatile than just gaming, then the Ryzen 9 3900X is the sensible selection.
