Our initial AMD Ryzen 3rd Gen. launch was built upon the Ryzen 7 3700X and Ryzen 9 3900X, both of which have impressed us, and the computer hardware media as a whole massively. However, now we’ll begin to round out the entire range that AMD have to offer, starting with the AMD Ryzen 7 3800X.

The Ryzen 7 3800X is based upon an identical framework to the Ryzen 7 3700X, sporting an 8-core, 16-thread layout and 32MB of cache, only with the TDP dialled right up to 105W, a huge 40W increase on the 3700X. With that comes a hefty base clock increase from 3.6GHz to 3.9GHz and a Boost clock increase of 100MHz to 4.5GHz when conditions are perfect.

With the latest 3rd Gen. Ryzen processors, AMD have changed the entire makeup and implemented a chiplet design, utilising the latest 7nm technology for the CPU cores (CCDs) and sticking with the more mature, and cheaper to produce, 12nm architecture for the IO die (cIOD), where a shrink in transistor size wouldn’t really affect performance. The 3rd Gen. CPUs use either one or two of those chiplets (CCDs), with each containing up to 8 cores. This means the AMD Ryzen 7 3800X is the current top-tier CPU using only a single CCD.

It stands to reason that with the increased TDP of 105W, the same as the 12-core Ryzen 9 3900X, we could see the Ryzen 7 3800X put up a good fight in specific tests, particularly something like gaming where maintaining a higher base clock can be directly attributed to a smoother gaming experience.

AMD have yet to sample the AMD Ryzen 7 3800X to the press, so we had a word with our good friends over at ASRock who were more than happy to provide us with a chip for a couple of weeks. We’ve used their ASRock X570 Taichi motherboard for testing,

The AMD Ryzen 7 3800X arrives at £379.99 in the UK and $399.99 in the US, putting it around £60/$60 more than the 3700X but in direct competition with the Intel Core i7 9700K; the 9700K sports 8 compute cores, just like the 3800X, but is missing Intel HyperThreading which leaves it 8 threads short. We’ll see how it compares to the 3700X and 9700K in our testing.

AMD on Zen 2:
Cloud computing, enterprise productivity, immersive visual experiences, gaming and streaming all demand increasing computing performance with optimal energy efficiency. From the very beginning, AMD engineers designed the new “Zen 2” core to meet those demands with more core throughput, larger caches, and powerful multi-threading capabilities.
