CPU Mini Review

Mini Review The Core i9-10900 10-Core 2.80GHz is a CPU based on a refinement of the 14nm++ Comet Lake-S microarchitecture. It offers 10 physical cores (20 logical), initially clocked at 2.80 GHz, which may go up to 5.20 GHz using 10 cores with Turbo Boost. The Core i9-10900 has 20MB of L3 Cache. The Intel Core i7-9820X 10-Core 3.3GHz is a high-end CPU based on the 14nm Skylake-X micro architecture. It is competing against AMD's 2nd Gen Ryzen Threadripper processors. It offers 10 physical cores (20 logical), initially clocked at 3.3GHz which may go up to 4.1GHz with Turbo Boost enabled, and 16.5MB of L3 Cache. Among its many features are Turbo Boost Max 3.0 technology, Hyper-Threading, Virtualization is activated. As an 'Extreme' variant, this processor has its multiplier unlocked and overclocking is possible. With a 165W TDP, the Core i9-9820X 10-Core is very power hungry and will require a high-end PSU. This CPU is likely to offer exceptional computational performance and will not be the bottlenecked in any modern gaming PC. It will be able to play all AAA titles.

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Core i9-9820X 10-Core 3.3GHz is massively better than the Intel Core i9-10900 10-Core 2.80GHz when it comes to running the latest games. This also means it will be less likely to bottleneck more powerful GPUs, allowing them to achieve more of their gaming performance potential.

Both the Core i9-10900 10-Core 2.80GHz and the Core i9-9820X 10-Core 3.3GHz were released at the same time, so are likely to be quite similar.

Both CPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings (assuming they are accompanied by equivalently powerful GPUs).

{ The Core i9-10900 10-Core and the Core i9-9820X 10-Core both have 10 cores. Games are not yet able to harness this many cores, so it is probably excessive if you mean to just run the latest games; however, if you intend on running a server with this CPU, it would seem to be a decent choice.

Both the Intel Core i9-10900 10-Core 2.80GHz and the Intel Core i9-9820X 10-Core 3.3GHz have the same number of threads. Both the Core i9-10900 10-Core and the Core i9-9820X 10-Core use hyperthreading. The Core i9-10900 10-Core has 2 logical threads per physical core and the Core i9-9820X 10-Core has 2.

Multiple threads are useful for improving the performance of multi-threaded applications. Additional cores and their accompanying thread will always be beneficial for multi-threaded applications. Hyperthreading will be beneficial for applications optimized for it, but it may slow others down. For games, the number of threads is largely irrelevant, as long as you have at least 2 cores (preferably 4), and hyperthreading can sometimes even hit performance.

More important for gaming than the number of cores and threads is the clock rate. Problematically, unless the two CPUs are from the same family, this can only serve as a general guide and nothing like an exact comparison, because the clock cycles per instruction (CPI) will vary so much.

The Core i9-10900 10-Core and Core i9-9820X 10-Core are not from the same family of CPUs, so their clock speeds are by no means directly comparable. Bear in mind, then, that while the Core i9-9820X 10-Core has a 0.5 GHz faster frequency, this is not always an indicator that it will be superior in performance, despite frequency being crucial when trying to avoid GPU bottlenecking. In this case, however, the difference is enough that it possibly indicates the superiority of the .

Aside from the clock rate, the next-most important CPU features for PC game performance are L2 and L3 cache size. Faster than RAM, the more cache available, the more data that can be stored for lightning-fast retrieval. L1 Cache is not usually an issue anymore for gaming, with most high-end CPUs eking out about the same L1 performance, and L2 is more important than L3 - but L3 is still important if you want to reach the highest levels of performance. Bear in mind that although it is better to have a larger cache, the larger it is, the higher the latency, so a balance has to be struck.

The maximum Thermal Design Power is the power in Watts that the CPU will consume in the worst case scenario. The lithography is the semiconductor manufacturing technology being used to create the CPU - the smaller this is, the more transistors that can be fit into the CPU, and the closer the connections. For both the lithography and the TDP, it is the lower the better, because a lower number means a lower amount of power is necessary to run the CPU, and consequently a lower amount of heat is produced.
