Introduction

AMD's Ryzen 3000 series processors might just be the most anticipated CPU and biggest potential market disruptor we have seen since AMD's original Ryzen launch.

Without a doubt, AMD made a pretty decent sized dent in their competitors' market share when they launched Ryzen, and now with many needed improvements to the Zen microarchitecture (now Zen2) and a node shrink from 12nm to 7nm, AMD is positioned quite well. However, marketing slides and talk is one thing, actually seeing the results is another, and today you get to see the fruition of AMD's promises.

Specifications

The 3900X is a 12 core 24 thread CPU with a huge L3 cache of 64MB and a 105W TDP. The 3700X is an 8-core 16 thread CPU with a pretty large L3 cache of 32MB with a TDP of 65W. Both CPUs come with the very nice Wraith Prism RGB cooler, and both CPUs offer the same IO, the focus of which is the new PCI-E 4.0 lanes.

Major architectural changes are seen all over the place. For starters, we now have an I/O die (IOD) and up to two Core Chipset Dies (CCD) per each Ryzen 3000 series CPU, although only one might be in use. Each CPU also has double the cache of their predecessors, which not only improves performance all around, but also is targeted for improving gaming performance.

The front end and backend of the CPU have been greatly improved, and AMD is claiming around a 15% IPC improvement, which we find to be a fair estimate. AMD also focused on improving on something they do well; simultaneous multithreading.

The platform has also been greatly improved, with all PCI-E lanes from the CPU and the chipset being PCI-E 4.0 lanes. There are also up to eight USB 3.1 Gen 2 (10Gbps) ports.

Pricing

The Ryzen 3900X and 3700X are priced at $499 and $329.
