In terms of overall gaming performance, the AMD Ryzen 7 3700X 8-Core 3.6GHz is massively better than the AMD Ryzen R7 1800X 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 over a year more recently than the Ryzen R7 1800X, and so the Ryzen 7 3700X is likely to have better levels of support, and will be more optimized for 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 Ryzen 7 3700X and the Ryzen R7 1800X 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 AMD Ryzen 7 3700X 8-Core 3.6GHz and the AMD Ryzen R7 1800X have the same number of threads. Both the Ryzen 7 3700X and the Ryzen R7 1800X use hyperthreading. The Ryzen 7 3700X has 2 logical threads per physical core and the Ryzen R7 1800X 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 Ryzen 7 3700X and Ryzen R7 1800X 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 Ryzen 7 3700X and the Ryzen R7 1800X both have the same clock frequency, this is by no means an indicator that the two CPUs will provide the same level of performance. 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 Ryzen 7 3700X and the Ryzen R7 1800X have the same L2 cache size, but the Ryzen 7 3700X has a 16 MB bigger L3 cache, so in this area, it wins out over the Ryzen R7 1800X.

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 30 Watt lower Maximum TDP than the Ryzen R7 1800X, 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 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.The Ryzen R7 1800X is a very high-end CPU based on AMD's 14nm, Zen microarchitecture. It offers 8 physical cores (16 logical), initially clocked at 3.6GHz, which may go up to 4.0GHz using Turbo Boost. It has an unlocked multiplier therefore it can be overclocked using traditional methods. It has 16MB 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 95W. It is on par with competitor processors. Among its many features, Simultaneous Multithreading, Cool n Quiet, CoolCore Technology, Extended Frequency Range (XFX), Pure Power and Precision Boost are enabled. It doesn't feature an integrated GPU. This CPU is likely to offer excellent computational performance and will not be the bottleneck in any modern gaming PC.
