Hardware specifications

At launch, the Ryzen 3 3300X is available at a price of about $120. It is an affordable CPU that uses the Zen 2 architecture and comes with all the benefits of this architecture, including support for PCI Express 4 (PCIe 4). For a comparison between PCIe 4 and PCIe 3, read: PCI Express 4 vs PCIe 3: Is there a performance improvement?. Just like all the other processors from the Ryzen 3000 series, the 3300X is built using the 7-nanometer manufacturing process.

AMD Ryzen 3 3300X and AMD Ryzen 3 3100

The AMD Ryzen 3 3300X has four cores and eight processing threads, clocked at a base frequency of 3.8 GHz. The maximum boost frequency, on a single-core, goes up to 4.3 GHz. This affordable processor has two fewer cores than the AMD Ryzen 5 3600 and 3600X, but their base and turbo clocks are similar. In fact, the 3300X has both a faster base clock (by 200 MHz) and a turbo boost clock (by 100 MHz) than a Ryzen 5 3600. Compared to the Ryzen 5 3600X, the boost clock offered by the 3300X is lower by 100 MHz, although their base clocks are the same. However, the AMD Ryzen 3 3300X also has a lesser amount of Level 3 cache memory: 16 MB vs 32 MB (3600X).

These observations make us think that the Ryzen 3 3300X looks like a Ryzen 5 3600X stripped of two cores. Either way, because it's able to sustain a high single-core boost frequency, the Ryzen 3 3300X looks like an excellent choice for those who want to build gaming computers on a budget.

CPU-Z details about the AMD Ryzen 3 3300X

The default TDP of the Ryzen 3 3300X is a mere 65W, and AMD also bundles a Wraith Stealth stock cooler with it. It is not a deluxe cooler, lacking RGB lighting, but it should do its job well. Anyway, it's better than nothing, which is what you get from Intel's similarly priced processors.

The AMD Ryzen 3 3300X supports fast DDR4 RAM running at 3200 MHz in dual-channel mode, although a sweet spot for the best price per performance ratio would be getting yourself some DDR4 DIMMs running at 3600 MHz.

The AMD Ryzen 3 3300X uses the AM4 socket and supports PCI Express 4. That means that, even if it is a budget processor, it provides plenty of headroom for those who, in the future, want to be able to use new PCIe 4 graphics cards, or SSDs for instance. Furthermore, AMD is also launching the new B550 motherboard chipset as we speak, which means that we should soon see mainstream motherboards on the market, with a more affordable price than existing X570 motherboards.

B550 motherboards are going to support Ryzen processors built on the Zen 2 architecture, as well as the ones using the next Zen 3 architecture. However, for now, if you don't need PCI Express 4, you can also use the Ryzen 3 3300X on older motherboards with chipsets such as X470, X370, or B450, albeit only with PCI Express 3.

The AMD Ryzen 3 3300X looks like an excellent computer processor. Its fast base frequency and the single-core boost clock should make it capable of handling even the newest games, without it becoming a bottleneck for your graphics card. Let's see what the benchmarks tell us:

Performance in benchmarks and games

We tested the AMD Ryzen 3 3300X processor on a PC with the following hardware and software:

To get a better idea about the performance offered by the AMD Ryzen 3 3300X, we compared its benchmarks results with other AMD Ryzen processors, including the 6-core Ryzen 5 3600X, the Ryzen 5 3600, and the recently launched Ryzen 3 3100.

First, we benchmarked the Ryzen 3 3300X using CPU-Z. In the Single Thread, this processor got a score of 490 points. It's an outstanding result that shows excellent single-core performance, which is especially important in gaming. The Ryzen 3 3300X is 2.4% slower than the Ryzen 5 3600X, 4.1% faster than Ryzen 5 3600, and 6.5% faster than the Ryzen 3 3100. Furthermore, according to CPU-Z, the Ryzen 3 3300X offers the same performance you would get from an Intel Core i7-7700K CPU.

Benchmark results in CPU-Z Single Thread

In CPU-Z's Multi-Thread test, we got a score of 2699. The Ryzen 3 3300X has only four cores, so we expected it to get a lower result than its 6-core Ryzen 5 brothers. The Ryzen 3 3300X got a score that was 26.2% lower than the Ryzen 5 3600 and 32.8% lower than that of the Ryzen 5 3600X. However, compared to the Ryzen 3 3100, the 3300X is 6.1% faster in multithreaded operations. Also, according to CPU-Z, the Ryzen 3 3300X is a bit faster (1.9%) than the Intel Core i7-7700K processor in the Multi-Thread benchmark. That's quite impressive!

To test the temperatures reached by the AMD Ryzen 3 3300X, we ran Prime95 to stress it, and we monitored it with Open Hardware Monitor. Unfortunately we received this processor without its stock cooler. That's why we had to use a different cooler: an ASUS ROG Ryuo 120. It is a more powerful and efficient cooler than the stock Wraith Stealth that you get with the Ryzen 3 3300X. Note that we measured the temperatures of the other processors in the chart using their stock coolers, so look at the following results with some reservations.

The AMD Ryzen 3 3300X processor reached some rather high temperatures, getting as hot as 93 degrees Celsius (199 degrees Fahrenheit). It's quite a lot and, with the stock Wraith Stealth cooler, the 3300X is probably going to throttle from time to time, in demanding games or apps.
