A month ago we published an article detailing AMD's plans to add Radeon Vega graphics to a single Ryzen CCX using AMD's more refined 14nm+ silicon, and today we will examine the new APUs.
The performance figures teased a month ago were very impressive, and today we will show you our results comparing the new Ryzen 5 2400G and Ryzen 3 2200G against competitors as well as Ryzen 3 and 5 processors already in the wild. The new Raven Ridge CPUs we are testing today offer enhanced technologies and are part of AMD's Ryzen 2000 series of processors, which are compatible with 300-series motherboards with a simple BIOS update.
The new APUs use a few new technologies including Precision Boost 2. Precision Boost 2 offers a much more granular boost on cores and a more dynamic boost range, so it's not just a few cores boosting or all. The improved slope should increase performance at stock and uses telemetry data to boost the cores while aiming for the best performance possible.
The Raven Ridge desktop CPUs utilize much of the same technology seen in the Ryzen Mobile APUs, and we detailed their new technologies in an article published in October of last year. AMD's Infinity Fabric is what links the Vega graphics to the CPU, media engine, and the rest of the APU. AMD has also improved on power sharing between the CPU and the GPU to improve power usage and performance. In the real-world, you won't stress the GPU and CPU to 100% at the same time, so it makes sense to produce a power rail system that can benefit mixed workloads over synthetic ones.
AMD is launching two APU SKUs, the Ryzen 5 2400G and the Ryzen 3 2200G. The 2400G will offer 4 cores and 8 threads in a single CCX, with a base clock of 3.6GHz and a boost up to 3.9GHz. It offers 11 Vega compute units with a clock up to 1250MHz. The 2200G offers 4 cores and 4 threads (no SMT) in a single CCX with a 3.5GHz base clock and a 3.7GHz boost. It will offer 8 Vega compute units with a clock up to 1100MHz. Both CPUs have the same L3 cache size, 65W TDP, and support up to DDR4 2933MHz.
The 2400G uses what is called Vega 11, and the 2200G uses Vega 8, these numbers correspond with the number of compute units in each integrated GPU. Both have 16 32-bit render output units, but the Vega 11 has 44 texture mapping units while the Vega 8 has 32 TMUs. The new integrated graphics are based on the big Vega 64 and 56 high-end GPUs, but they are scaled down a lot and don't use HBM.
The platform has also changed a bit. The new APUs have x8 PCI-E 3.0 for graphics cards and x8 for other devices. When we talk about other devices, we are referring to the FCH (chipset), which takes up x4, leaving x4 PCI-E 3.0 for other connectivity. In this case, most motherboards with an x4 PCI-E 3.0 M.2 slot will still operate at x4 PCI-E 3.0 (we tested, and our M.2 slot was running x4 PCI-E 3.0).
It's also worth noting the display capabilities of the new APUs. They support FreeSync and HDCP 1.4/2.2. That means they can output to gaming monitors and utilize FreeSync while also streaming 4K+HDR content.
The Ryzen 3 2200G will cost $99, and the Ryzen 5 2400G will cost $169.
