The CPU

The Ryzen box has already been widely publicized, but if you wanted a closer shot of what's written on the sticker, here you go.

Packaging is very simple, the CPU and a case badge sit inside a plastic cage. Be careful handling the CPU, it has many pins, and if you haven't dealt with a CPU with pins in a while, do your best not to bend any pins because straightening them is very hard.

The Platform

AMD's Ryzen CPUs move one step closer to eliminating the motherboard chipset. AMD's CPUs integrate not only PCI-E lanes for the GPU but also some storage and USB. If you don't want to spend a lot of money on an X370 motherboard, the B350 chipset also allows for overclocking. Some people mentioned they didn't see any mini-ITX motherboards for Ryzen, and that is because of X300. The X300 chipset is a tiny chip that has no IO and allows for overclocking, its main purpose is to validate the CPU is authentic and provide some security measures for the system.

 

We should see some very interesting mini-ITX motherboards for Ryzen CPUs. The one thing that AMD's chipsets have over Intel's is integrated USB 3.1. Now, I won't lie, it can be confusing as to what IO comes from where with the chipsets, AMD tries to explain it in the charts but isn't very clear on everything. So I looked for another source.

The motherboard in this review is the ASUS Crosshair VI Hero, and the block diagram explains exactly what the IO split is. The Ryzen CPUs have x16 PCI-E 3.0 lanes for the PCI-E slots, as well as an x4/SATA connection for M.2 storage. The HD audio/I2C bus is also located in the CPU (on Intel platforms it's in the PCH). We also get four USB 3.0 ports from the CPU as well. The CPU is connected to the Promontory X370 FCH by an x4 PCI-E connection (similar to Intel's x4 DMI). The promontory X370 chipset offers eight PCI-E 2.0 lanes (almost identical to X99, but nothing compared to Z270), that is where you get your LAN (one lane), extra USB 3.1 (two lanes for 10Gbit/s), and WIFI/BT adapter.

 

The chipset also six USB 3.0 ports, same as the CPU for a total of ten, four more than Intel Z270. The chipset offers eight SATA 6Gb/s ports and a bunch of USB 2.0. It's also where the native USB 3.1 ports come from. It's an interesting choice regarding IO selection, especially with the heavy proliferation of x4 PCI-E 3.0 M.2 drives.

 

 

Test Setup

At the Ryzen Tech Day event in San Francisco, I picked up our Ryzen test kit, and this is what I received.
