Ryzen 3900X & 3700X VS 9900K & 2700X
|THEY ARE HERE! They are finally here, AMD’s Ryzen 3900X and 3700X CPUs, and my god are they beautiful. Now since AMD has been rather open about pretty much everything already, I’m going to skip a lot of the technical side here and refer you to articles from people like Anandtech who do a much better job than I ever could anyway, but I will cover a few key points real quick.
First, core counts and clock speeds. The 3900X is a 12 core monster, with 24 threads, and has a base clock 3.8GHz and boosts to 4.6Ghz although all core is more like 4-4.4 depending on the application.
The 3700X is a more normal 8 core, 16 thread, running at 3.6Ghz base, and 4.4Ghz boost – of which it can – at times – boost all 8 cores to that 4.4ghz.
Cache wise these chips have double last gen, so 64mb for the 3900x and 32mb for the 3700x, which AMD says gives around a 20% performance improvement in games alone. Also, RAM speed wise, they’ve worked rather hard to be able to decouple the infinity fabric frequency from the RAM frequency at higher speeds, meaning Ryzen can now handle upwards of 5GHz RAM, although the ideal frequency AMD suggest is 3600MHz at CL16.
And finally, these chips support PCIe Gen 4 – that doesn’t mean much for GPUs right now, and probably won’t for a few years yet, but does mean a lot for SSDs which you’ll see in a few days time when I review this, the Aorus 2TB Gen 4 M.2 SSD and see just how insanely fast it is.
So, performance. These are great, the synthetic cinebench test shows that both new chips have caught up to intel’s flagship 9900K in single threaded performance, and come real close to both beating it in multithreaded too. The end result for games is that they are all really, really close. Let’s take a look.

I also ran a 10 minute premiere test render with 4K 30mbps footage rendering with CPU only exporting with the “High Quality 4K” preset, and found that the 9900K and 3700X were pretty much tied, despite it’s much lower price, and of course the 12 core ripped through them all – and as you can see, the 2700X to 3700X is a really big jump despite the same core count too.
Premiere Pro Render:
CPU Name | Render Time (s) |
9900K | 880 |
2700X | 1082 |
3900X | 832 |
3700X | 904 |
So what’s the conclusion here? It’s probably the same one you’ve heard from most other tech reviewers today – these chips are amazing. Their single core performance now fully matches Intel. Their gaming performance generally does too, and the fact they offer a 12 core for the price of Intel’s 8 is just unbelievable.
Now there is one spanner in the works here, and that’s X570 motherboards. Mostly thanks to PCIe Gen 4, they are expensive. Like, really expensive. The X570 version of the Gigabyte master board is looking to cost nearly £400, whereas the existing Z390 Master board only costs around £250, but there are some lower end offerings, and most X470 boards should get bios updates to support the new chips, although it may be a bit of a pain to deal with.
So, would I put either of these in my rig? 100% yes. As a content creator, I have my eye on the 12 core, but for everyday folks, the 6 or 8 cores are incredible options and well worth a look, and in fact, your money.

They are back, and back with a bang. These are the new AMD Ryzen 3900X & 3700X, and they are really, really impressive. How impressive? Well lets compare them to the last gen 2700X, and Intel’s 9900K.
