||The Ryzen 9 5950X 16-Core 3.5GHz is a high-end CPU based on AMD's 7nm+ Zen 3 microarchitecture. It offers 16 physical cores (32 logical), initially clocked at 3.5GHz, which may go up to 4.9GHz using Precision Boost.
It has an unlocked multiplier, therefore, it can be overclocked using traditional methods. As an AMD 'X' CPU, the Ryzen 9 5950X can use eXtended Frequency Range (XFR) for automated overclocking.
It has 32MB of L3 Cache. Level 3 cache is a static memory bank of a processor and it is used to feed it instructions. This processor also supports DDR4 based RAMs with maximum memory support of 64GB.
It has a maximum Thermal Power Design of 105W. It is power efficient compared to competitor processors.
Among its many features are Simultaneous Multithreading, Cool n Quiet, CoolCore Technology, Extended Frequency Range (XFR), Pure Power and Precision Boost are enabled.
||The AMD Threadripper 3990X 64-Core 3.0GHz is an extremely high-end (HEDT) CPU based on AMD's 7nm Zen 2 microarchitecture. It offers 64 physical cores (128 logical), initially clocked at 3.0Hz, which may go up to 4.5GHz using Turbo Boost. As of 2020, it is the only HEDT processor with 64 cores.
It has an unlocked multiplier, therefore it can be overclocked using traditional methods.
It has 260MB of L3 Cache. Level 3 cache is a static memory bank of a processor and it is used to feed it instructions. This processor also supports DDR4 based RAMs with maximum memory support of 2TB.
It has a maximum Thermal Power Design of 280W, making it one of the most power intensive processors on the market. It also has a maximum temperature of 68C so appropriate CPU cooling will be necessary.
Among its many features are Enmotus FuzeDrive for AMD Ryzen, AMD SenseMI Technology, AMD Ryzen VR-Ready Premium, Virtualization, AES, AVX2, FMA4, XFR (Extended Frequency Range)
It doesn't feature an integrated GPU.
The Threadripper 3990X 64-Core 3.0GHz's high core count and middling clock speed make it a decent but extremely expensive option for gamers. This CPU is better suited to prosumers and content creators who may be running high-intensity threaded applications. It will run AAA games very well. While a high clock speed is a priority for gaming, 64 cores is truly excessive for any gaming applications in 2020 and beyond.
