AMD has officially launched two new game-focused entry-level CPUs: AMD Ryzen 3 3100 and Ryzen 3 3300X. These are eight-threaded / four-core processors based on the Zen-2 architecture, making them more energy efficient than the competition.
Ryzen 3 3300X is not only an overclocked Ryzen 3 3100, since all four cores on the 3300X are on the same CCX (CPU complex) and uses the 4 + 0 configuration, where a CCX is completely inactive. While the Ryzen 3 3100 uses two CCXes with two cores on each CCX (2 + 2 configuration). For this reason, the Ryzen 3 3300X has a single 16 MB L3 cache block and also reduces latency between the two cores. The L3 cache on Ryzen 3 3100 is split in half. The Ryzen 3 3300X will have lower core latency and higher cache memory which indicates higher single-core performance that will help in activities such as video games.
AMD Ryzen 3 3300X, Ryzen 3 3100: Features
AMD Ryzen 3 3300X offers slightly higher clock speed and higher performance than the Ryzen 3 3100. It comes with a base clock speed of 3.9 GHz and a boost clock speed of 4.3 GHz with a total L3 cache of 16 MB. The CPU has a default TDP of 65 W and supports PCIe 4.0 for faster data transmission from SSDs and graphics processors. The package is also equipped with a Wraith Stealth cooler, which should be more than enough to maintain the optimal operating temperature.
The AMD Ryzen 3 3100 is also a quad-core processor, with a slightly lower clock speed than the Ryzen 3 3300X. It comes with a basic operating frequency of 3.6 GHz and a clock boost of 3.9 GHz with a total L3 cache of 16 MB.

Are they a good choice to assemble a new PC?
Ryzen 3 3100 and Ryzen 3 3300X look like a great pair of CPUs for those planning to build a new gaming PC on a low budget. Because these CPUs are equipped with support for PCIe 4.0, which is not even present on the flagship Intel CPUs yet, these two processors will definitely offer good longevity. Between the two, the Ryzen 3 3300X is definitely a better choice as it has lower core latency and higher single-core and multi-core performance, thanks to higher clock speeds at a slightly higher cost than the Ryzen 3 3100 model.
