"The AMD Ryzen 5 2400G and Ryzen 3 2200G Review: Return of the APU"

I'm looking forward to all the Mini-Desktop systems that make use of these RR Desktop APU SKUs. There was the ZOTAC ZBOX MA551 introduced at CES this year and hopefully there will be loads of different offerings.

HP makes a business class mini-desktop with Intel's core i series processor options(35 and 65 watts) but hopefully there can be a Raven Ridge variant from HP and in that smaller form factor there is only room for integrated graphics. The nice thing about HP's mini-desktops and even some HP business laptops is that they come with socketed processors.

So AMD's Raven Ridge APUs have a definite sdvantage in these small form factor offerings where there csn be only integrated graphics and Integrated graphics is where Raven Ridge is really set apart from the competition. It should be noted that a lot of productivity applications are using OpenCL to accelerate workloads on the GPU in addition to the CPU. So more comparison testing of these GPU accelerated featers in SOC's/APUs needs to be done in the future.

It looks like HP has done a good job redesigning their line of mini-desktop offerings and they are no longer as ugly as they once where and they even have a new EliteDesk 800 Desktop Small Form Factor system that looks nice also. But I'm really wanting to see more mini-desktop full and barebones systems tested form Intel(That Intel/Vega EMIB/MCM) SKU as well as any Raven Ridge APU mini-desktop variants.

I guess that AMD will at sometime be introducing a Pro Raven Ridge APU variant for business class mechines the same as AMD did for its Ryzen CPU only Desktop Variants.
So systems from Dell, HP, Lenovo, and others with integrated graphics that is a bit more performant on thoe smallest of the small types of mini-desktop systems.

That Intel/Vega SKU with the Vega Graphics and 4GB of HBM2 also represents the first opportunity to stress test Vega's HBCC/HBC(HBM2) IP for gaming. So Maybe trying out some Game texture packs that are much larger that 4GB.

I also interested in hearing about any new gaming titles that will be making use of more FP16, in addition to DX12/Vulkan, in games targeting these lower power APU based systems with Vega Graphics both AMD's APUs and Intel's SOC/Vega on an MCM SKUs.

It's nice to hear testing is being done on the effect of memory speed scaling on the graphics of the 2400G, however would it possible to quickly test if CPU performance also scales with memory speed, we know it did when the CPU had two CCX's but now RR only has a single CCX does that still hold true?

On the 2200G and 2400G parts, can you also please look what impact the size of the frame buffer has?

February 16, 2018 | 03:37 AM - Posted by WhyMe (not verified)

It shouldn't have any as most new games are UMA aware, setting the frame buffer in the BIOS is mainly a throw back to when games checked how much VRAM was available before running, with UMA the OS allocates as much, or as little, memory as needed to either the CPU or GPU depending on demand.

Thanks whyme, you're right. I was basing my request on a Jayztwocents video, but it turns out he was a bit more drama than data. Hardware Unboxed did a very comprehensive review of frame buffer impacts and found it negligible.

How come you didn't show a 487 chip this time?

But then, I checked the episodes 186, 187, 286, 287, 386, and 387, and you didn't show the chips either.

Just put together a build with a 2200G and the same motherboard, I wanna say when I plugged in my 4k samsung Monitor it was full 60hz. Same with my 4k tv.

Had to update the bios though, luckily I had a 1300x around.
