ZEN was bronze, ZEN2 was silver and ZEN3 is gold
The AMD Ryzen 9 5900X, together with the rest of the Ryzen 5000 series, finally beats Intel out of the race for the best processor for PC games .
Not only has Intel not yet implemented PCIe 4.0 support, making AMD processors more comprehensive and future-proof, but AMD offers a better performance.
Functions and chipset
The AMD Ryzen 9 5900X is based on the Zen 3 architecture, which may superficially resemble Zen 2 - after all, both are 7 nm in size.
But AMD has redesigned the architecture from the ground up to improve IPC performance and efficiency to the point where nothing is left to be desired.
The biggest difference in architecture from Zen 2 to Zen 3 is that instead of two core complexes (CCX) per computer chip (CCD), each computer chip has only [i] one [/ i] core complex, with each CCX having up to 8 cores instead of 4.
Since the cache is so important for gaming performance, this change along with the higher clock speeds massively increases gaming performance. AMD has increased performance across the board here.
The AMD Ryzen 9 5900X is a 12-core processor with 24 threads and a boost clock of up to 4.8 GHz.
It has the same TDP (Thermal Design Power = "" processor temperature "") of 105 W as the Ryzen 9 3900X and reached a maximum of 142.27 W in tests. This shows how much more efficiency AMD could get out of Zen 3.
This change not only reduces latency when cores communicate with each other, but also means that each CCX has access to a full 32 MB of L3 cache instead of being limited to 16 MB of the material in Zen 2.
This means that the Ryzen 9 5900X with 64 MB has the same amount of L3 cache as the Ryzen 9 3900X, but each core has direct access to 32 MB on the 5900X instead of 16 MB on the 3900X.
The AMD Ryzen 9 5900X is the fastest Processorever tested on a mainstream platform.
Another big winning point is that the chipset has not been replaced. X570 motherboards are still the top-end boards for AMD Ryzen 5000 processors.
This is great news for those who want to upgrade from an older Ryzen processor.
The Ryzen 9 5900X predecessor not only outperformed its "big brother" in almost all tests, but its main competitor - the Intel Core i9-10900K - outperformed AMD's Ryzen 9 5900X in almost all tests.
AMD has finally claimed the single-core performance crown from Intel. This is strongly reflected in the benchmarking software.
More impressive, however, is how this is reflected in the pure gaming performance. With Zen 3, AMD wanted to develop the best processor for games and has obviously achieved this goal.
More importantly, this one of the biggest improvements of the generation that have been observed in processors so far.
This is especially true when you consider the massive generation leaps of the best graphics cards. If you look at the RTX 3080's performance at 1080p and 1440p, you'll need a strong gaming CPU to pair it with - the Ryzen 9 5900X would be an excellent gaming companion here.
The AMD Ryzen 9 5900X is an incredibly powerful gaming processor that delivers single-core performance far beyond the latest generation CPUs.
A large percentage of games will experience a massive performance boost.
Ryzen is Ryzen, and with 12 cores and 24 threads, the AMD Ryzen 5900X is an absolute beast for multi-core workloads.
The massive increase in single-core performance contributes to the increase in multi-core performance.
Consequently, if each core is faster, the entire processor benefits.
Because the AMD Ryzen 9 5900X offers such a huge leap in single-core performance over the Ryzen 9 3900X, the upgrade is really worth it, especially if one of the most important things you do with your PC is play PC games.
Conclusion
The AMD Ryzen 9 5900X is the "monster" of a CPU and brings the biggest gen-on-gene leap in single-core performance in years.
This makes the processor stronger across the board.
And the best part is: You don't even need a new motherboard!
In fact, with the AMD Ryzen 9 5900X, there's no reason to buy an Intel processor for the gaming PC you set up.
The AMD Ryzen 9 5900X is the fastest processor ever tested on a mainstream platform.
In the results of almost all tests, the Ryzen 9 5900X achieved better results than its predecessor (the Ryzen 9 3900X).
Its main rival, the Intel Core i9-10900K, was also defeated.
