Intel Core i9-12900K vs AMD Ryzen 9 5900X Performance Review

Synthetic System Benchmarks

We are going to start with synthetic system application benchmarks on this page. Gaming performance will be shown later on.

PCMark 10

Standard PCMark Benchmark

Intel Core i9-12900K PCMark 10 Standard PCMark Benchmark Graph

In the first graph, we are looking at PCMark 10 standard benchmark test, which is an overall system test. PCMark 10 runs a gauntlet of different office, content creation, and desktop workloads. The new Intel Core i9-12900K scores 9277 which is 8% overall faster than the AMD Ryzen 9 5900X. This is an overall system test, which takes many things into account, some of which are the same between the system like the SSD and GPU performance. Therefore, for a CPU alone to make an 8% difference in performance here is pretty noteworthy.

PCMark Application Benchmark

Intel Core i9-12900K PCMark 10 Applications Benchmark Graph

In this graph, we are looking at PCMark 10’s Applications Benchmark.  This test is very specific, it tests the performance of Microsoft Office, using Excel, Word, PowerPoint, and even Edge. We are using Microsoft Office 2021 for these tests. This one is more significant, as it directly tests Microsoft Office performance, something a lot of people use on a daily basis. According to this test, the new Intel Core i9-12900K is 12% faster than the AMD Ryzen 9 5900X. That means Microsoft Office applications can actually perform faster on the 12900K. If you do a lot of heavy MS Office work, the 12900K will benefit you.

3DMark

CPU Profile

Intel Core i9-12900K 3DMark CPU Profile Max Threads Graph

We are using 3DMark Professional’s CPU Profile test. This test specifically tests CPUs and reports an overall score, it tests various thread counts. We are going to report on the “Max Threads” and “1-Thread” results only. Remember, both CPUs can operate on 24 processing threads. In the Max Threads test, the Intel Core i9-12900K still comes out on top, by 14% faster than the Ryzen 9 5900X despite 8 of the 12900K’s cores/threads being Effiecny Cores. That’s impressive.

Intel Core i9-12900K 3DMark CPU Profile 1-thread Graph

In this test above we are testing just a single thread of performance, this really shows how good single-thread performance differs. Even working on just 1-thread the Intel Core i9-12900K comes out on top, 11% faster than the AMD Ryzen 9 5900X.

Geekbench 5

Intel Core i9-12900K Geekbench 5 CPU Benchmark Multi-Core Graph

Next up we have the latest version of Geekbench 5.  This benchmark tests overall CPU performance and can show us a result in both multi-core and single-core performance. This one is majorly different. In Geekbench 5 the Intel Core i9-12900K comes out 37% faster than the AMD Ryzen 9 5900X in overall multi-core performance! That’s a very large and significant difference in performance right there.

Intel Core i9-12900K Geekbench 5 CPU Benchmark Single-Core Graph

The single-core performance is also very strong on the Intel Core i9-12900K. It is 14% faster than the AMD Ryzen 9 5900X in Geekbench 5.

PassMark Performance Test

Intel Core i9-12900K PassMark PerformanceTest CPU Mark Graph

PassMark’s PerformanceTest CPU Mark benchmark tests various CPU workloads, including encryption. The new Intel Core i9-12900K scores 44240 which is 11% faster than the AMD Ryzen 9 5900X in CPU Mark score.
