AMD Ryzen 9 3900XT 12-Core 3.8 GHz Socket AM4 Desktop Processor

Three years ago, I build a system with an Intel i7 7700K. Last month, I replaced that Intel with an AMD R7 3800X, which advertised a 4.5GHz speed, but typically delivered about 4.2 for single core loads and 4.0 for all core. That isn't unusual for Ryzen CPU's, where your "up to" speed and your actual speed will vary by 200-300MHz. The single core speed just wasn't enough of an improvement over my old Intel. It also isn't worth my time (or yours) trying to mess with overclock settings when the chip is pretty well optimized out of the box. Enter the new XT processors. I could have swapped up to the 3800XT, which would have given me the speed bump I wanted, but would have cost $70 more for just that extra MHz. The 3900XT here was $170 more, but delivered 50% more cores as well as the same low-load speed of the lesser XT chip. It's the better value, and likely the more future-proof solution as well, as more software is written to take advantage of high core counts. So what does this 3900XT do? It does indeed hit the 4.7GHz advertised speed on 2 cores (4766MHz to be exact). It will do this while you're browsing the web or otherwise not doing much. Low-to-Medium use cases (e.g. games) will see the chip turbo up to 4.2-4.5GHz. The heaviest loads will see a boost to 4.0-4.2GHz. The exact number depends on the specific kind of program being run. In general, it's a 5-10% improvement over the 3800X. Your exact chip will vary a bit from these figures, likely less than 100MHz. It might also depend on your cooling setup. I stuck my 3900XT into a ITX box and a compact heat sink (pictured). More robust cooling and a more aggressive PBO (a built-in overclocking function) could probably net you slightly better performance. Again, on the order of 100-150MHz. So you could, potentially, see 4.7+ top speeds and 4.6 in-game turbos. However, AMD doesn't leave performance hanging out there. The main thing to consider is why this over the 3900X (no "T") which can be had for $70-100 less. In my case, I was choosing the better binning, the better chance of hitting higher low-thread clocks, and (preferably) lower heat. In short, I wanted a sure bet. The 3900XT delivers. This chip, unless you're hitting all 12 cores with 24 threads, actually runs as cool or cooler than my 3800X. So if you're looking for a lot of GHz and a lot of cores, and money isn't really an object, get this. There will be something new around the corner (there always is) and at that point, maybe you should get that instead. Right here, right now, there isn't a lot that's better.

This was an upgrade from the 2700X, so that's my basis for comparison (being as the rest of the system is identical). I picked up the XT variant, but how much difference there is between the X & XT is debatable. In terms of power draw, it beats the 2700X handily, with a stable all-core overclock of 4.350GHz at ~1.34v, whereas the 2700X required closer to 1.41v for the same clockspeed. Interestingly both the 2700X & 3900XT have similar top frequencies, at least that's my experience so far. The 3900XT runs much, much hotter than the 2700X, and that's even with a very substantial custom loop (360×30, 240×45 & 360×80 rads). Idle temp is low 40s, under load it can easily jump to the low 80s. The 2700X was ~10°C lower across the board. Whether this is something to do with AMD changing how the temperature is reported (that is pure speculation on my part) or some other issue I'm not sure. Online I found many users had similar experiences vis-a-vis the higher temps. But it's still within spec, so I would just say make sure you have a decent cooling solution. Overall though I'm pleased with it. How much difference users notice depends greatly on what you're upgrading from, and what you're using your system to run. If you're currently using an 8 core Ryzen processor (any generation) and are using your system mostly or exclusively for gaming, I might hold off until prices come down, because the difference you'll notice will probably be fairly modest. Which for $600 or $700 is not a very good ROI.

Sensational chip. Upgraded from a ryzen 7 1700x. Flight sim 2020 frame rates went from 19 to 45 with my 1080ti.
