Intel Core i9-10900K Beats AMD Ryzen 9 3900X CPU In Latest Benchmark Leak?

The Intel Core i9-10900K Comet Lake-S 10 Core Desktop CPU has once again appeared online. The 10th Generation flagship desktop processor from Intel appears to be finetuned and ready to take on AMD Ryzen 9 3900X CPU. The benchmarks of the Intel’s most powerful upcoming mainstream desktop processor was tested on Z490 motherboard and not an OEM branded LGA 1200 socketed motherboard, and the results are quite consistent with the expectations.

Intel may have been stuck on the 14nm Comet Lake for quite some time, but the company has nearly perfected the rather archaic fabrication node. The latest Intel top-end CPU, the Core i9-10900K Comet Lake-S has been regularly appearing online and was initially reported to be falling short of its direct rival, the on AMD Ryzen 9 3900X CPU. However, it turns out the limitations and shortcomings during the earlier benchmarks were owing to the use of unoptimized hardware.

Intel Core i9-10900K 10 Core CPU On Z490 Motherboard Benchmark Results:

Intel Core i9-10900K is the Flagship Intel CPU from the Comet Lake-S mainstream desktop family. Although it is still based on the same Skylake architecture, which is based on the rapidly aging 14nm fabrication process, there have been very significant revisions, which has allowed Intel to bump up clock speeds per core as well as pack more cores per CPU die.

The latest benchmarks indicate that the Intel Core i9-10900K scores 28940 points in the 3DMark Firestrike benchmark. The benchmark setup consisted of 16GB RAM (2x 8GB DDR4 memory) running at 3200 MHz. The same setup for the AMD Ryzen 9 3900X CPU returned a score of 30,415 points.

Simple math will indicate the AMD processor is still 5% ahead of the 10 core Intel CPU. The main reason behind the not so significant difference in results is that Intel has a massive clock advantage against AMD’s ZEN 2 architecture. However, the AMD CPU packs more cores and threads.

The benchmarks that allegedly leaked earlier this year in January, indicated that Intel has significantly improved the 10th Generation Core i9-10900K when compared to 9th Generation Core i9-9900K. However, the previous report also mentioned that Intel hasn’t made very much, if any, gain on individual core clock speeds. This aspect was becoming the shortcoming apparently due to unoptimized test platforms.

Intel Core i9-10900K 10 Core Desktop CPU Vs. AMD Ryzen 9 3900X CPU:

The Intel Core i9-10900K packs 10 Cores, 20 Threads, a total cache of 20 MB, supports DDR4-2933 MHz dual-channel memory, and sports a 125W TDP. The CPU has a base frequency of 3.7 GHz and a boost frequency of 5.1 GHz. However, using Intel’s Turbo Boost Max 3.0 technology, the processor can temporarily go up to 5.2 GHz on a single-core. However, it also sports a 4.9 GHz All-Core Boost. Serious users can also benefit from the Enhanced Core and Memory Overclocking capabilities.

Based on the 7nm ZEN 2 core Architecture, the AMD Ryzen 9 3900X packs 12 Cores and 24 Threads. The chip has 64 MB of L3 cache in addition to the 6 MB of L2 cache. The CPU comes with a Base Clock of 3.8 GHz and a Boost Clock of 4.6 GHz. Despite the specifications, the chip is quite energy efficient, clocking in at just 105W TDP.

Based on the new benchmarks, Intel and AMD’s flagship desktop CPUs could be headed in different directions, and hence, catering to a completely different buyer category. The Intel Core i9-10900K should appeal to buyers who demand high single-threaded performance, higher Clock Speeds, better-overclocking capabilities, and robust Memory Support.

Meanwhile, the AMD Ryzen 9 3900X CPU offers higher multi-threaded performance, new features on the 7nm node, cooler running and better efficiency, more Cores, Threads, and Cache memory. Incidentally, the latest AMD flagship AMD Desktop CPU also offers a great value for money upfront.
