Alright, it's time for some photos. We received two Ryzen 3000 Series processors. Amazing, that a completely different architecture and chiplet design and thus a totally new processor is still at Socket AM4, and thus works on selected 300/400 and X570 chipset based motherboards.




The Ryzen 7 3700X processor clocks in at a base clock of 3.60 GHz, yet can Turbo to 4.40 GHz depending on load levels versus active threads. The Ryzen 9 3900X clocks in at a base clock of 3.8 GHz, yet can Turbo to 4.6 GHz depending on load levels versus active threads (with the right conditions). These are considerable frequencies over the previous generation.


Given it's an 8-core architecture per die, AMD is really nicely managing that clock frequency. We quite honestly expect the Ryzen 7 3700X to be a popular processor, 8-cores / 16 threads at 329 USD. That means pricing is spot on against last-gen yet with added IPC and perf improvements.


For best fine-grained Turbo support, we do recommend a series 400 or 500 motherboard, X470/X570 of course. Pop in a mainstream or high-end graphics card and you'll have a very sweet gaming rig competing with Intel's finest. Should you want to use these procs with an older 300 or 400 series chipset, with a BIOS update these processors will work well (you need to update to a compatible BIOS prior to installing the new processor of course). We tested, there is no performance difference other than the new motherboards offer PCIe Gen 4.0 and they have stronger VRM designs and more features that come with them, like new AX WIFI on selected motherboard models.


We test with X570 today and the Ryzen 7 3700X (8c/16t) and Ryzen 9 3900X (12c/24t). We'll use liquid cooling on this CPU, however, given the temperatures. Any decent heat pipe cooler will work fine as well. Also, the X models all receive a very decent Wraith Prism cooler (with aRGB led system).



For this review, we'll be using the all-new X570 based ASUS RoG Crosshair VIII Hero (Wifi), one of the more premium motherboards available.
