In terms of overall gaming performance, the AMD Ryzen 7 3700X 8-Core 3.6GHz is massively better than the Intel Core i7-9800X 8-Core 3.8GHz 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.

The Ryzen 7 3700X was released less than a year after the Core i7-9800X 8-Core, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

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 i7-9800X 8-Core and the Ryzen 7 3700X both have 8 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 i7-9800X 8-Core 3.8GHz and the AMD Ryzen 7 3700X 8-Core 3.6GHz have the same number of threads. Both the Core i7-9800X 8-Core and the Ryzen 7 3700X use hyperthreading. The Core i7-9800X 8-Core has 2 logical threads per physical core and the Ryzen 7 3700X 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 i7-9800X 8-Core and Ryzen 7 3700X 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 i7-9800X 8-Core has a 0.2 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. As such, we need to look elsewhere for more reliable comparisons.

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 Core i7-9800X 8-Core has a 4096 KB bigger L2 cache than the Ryzen 7 3700X, but on the other hand, it is the Ryzen 7 3700X that has a 15.5 MB bigger L3 cache than the Core i7-9800X 8-Core. In this case, the L2 size is probably what counts, so the Core i7-9800X 8-Core is likely superior in this area.

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.

The Ryzen 7 3700X has a 100 Watt lower Maximum TDP than the Core i7-9800X 8-Core, and was created with a 7 nm smaller manufacturing technology. What this means is the Ryzen 7 3700X will consume significantly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill significantly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

CPU Mini Review

Mini ReviewThe Intel Core i7-9800X 8-Core 3.8GHz 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 8 physical cores (16 logical), initially clocked at 3.8GHz which may go up to 4.4GHz 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 i7-9800X 8-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.The Ryzen 7 3700X 8-Core 3.6GHz is a high-end CPU based on AMD's 7nm Zen 2 microarchitecture. It offers 8 physical cores (16 logical), initially clocked at 3.6GHz, which may go up to 4.4GHz using Precision Boost. It has an unlocked multiplier, therefore, it can be overclocked using traditional methods. As an AMD 'X' CPU, the Ryzen 5 3700X 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 65W. 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.
