Rumours of a further AMD Ryzen 5000 series desktop processor have been circulating for quite some time, mainly involving Ryzen processors without the X suffix. Recently, Twitter user @tum_apisak spotted AMD Ryzen 9 5900 in the new benchmark.
The AMD Ryzen 9 5900 is essentially a power-optimized version of the AMD Ryzen 9 5900X, retaining the same 12-core, 24-thread specs and 64MB L3 cache, the most significant difference being a 65W TDP. With tighter power control, the Ryzen 9 5900 operates at a lower frequency, with a base frequency of 3GHz, 700MHz, more melancholy than the Ryzen 9 5900X. Still, the acceleration rate is less affected, only 100MHz slower than the Ryzen 9 5900X, at 4.7GHz.
At the lower TDP, many people will wonder how different the Ryzen 9 5900 is compared to the Ryzen 9 5900X. While UserBenchmark doesn't capture everything, it can at least give you a basic idea of performance.
Benchmark results show that the single-threaded performance of the Ryzen 9 5900X is 5% better than that of the Ryzen 9 5900, and multi-threaded performance is 7% better. On the other hand, the Ryzen 9 5900 has 7% less memory latency than the Ryzen 9 5900X. Given that the power consumption of the Ryzen 9 5900 is significantly lower than that of the Ryzen 9 5900X, it's an excellent product and probably the most balanced and perfect Zen 3 architecture processor currently available for the consumer market.
The only downside is that the Ryzen 9 5900 will likely be available only to OEMs like the Ryzen 4000 series APUs.
