Will Judd of Eurogamer recently reviewed the AMD Ryzen 3 3100 and 3 3300X…

These mainstream processors could become a fast favourite with system builders, and look much more capable than their predecessors thanks to a few key advancements. Firstly, both CPUs boast four Zen 2 cores, so they should offer noticeably better single-threaded performance than their Zen and Zen+ predecessors from earlier Ryzen generations. The efficiency advantages inherent in switching from a 12nm to a 7nm process also allow for higher boost frequencies, which are set at 3.9GHz on the 3100 and 4GHz flat on the 3300X. These CPUs also support SMT (simultaneous multithreading), a first for a Ryzen 3 processor. Having eight threads available should make these chips better suited for content creation roles, and could help in games built on more modern engines as well.

These changes alone should result in a big shift in performance, but there are more subtle upgrades here too. The L3 cache on the 3300X has doubled in size compared to the 2300X, for example. This means that these processors don’t need to rely on data being streamed in from RAM as often, which speeds up processing and helps these chips pair better with slower-frequency RAM. Despite these advancements, TDP remains at 65W, with the included Wraith Stealth cooler obviating the need for a third-party AiO or air cooler for most use cases.

All of this looks promising, but only the crucible of real-world testing will determine whether these chips can live up to their potential in what is an intensely competitive space. Thankfully, we’ve had the Ryzen 3100 and 3300X in hand for the past few weeks to answer that question.


Despite costing less than every other CPU represented, the 3100 manages to tie the Core i5 9600K in single-core performance and outperform the Ryzen 2600 and 2700X by around 12 per cent. The 3300X is even more impressive, with a single-core score that exceeds the Core i7 9700K and only falls behind the Ryzen 9 3900X and Core i9 9900K. The multi-threaded results are a different story though, with the four physical cores and eight threads of the 3300X managing a little less than 2600 points. That’s close to the Core i5 9600K, but the greater core counts of the rest of AMD’s lineup translate into big performance wins.
