Contents.Memory Matters How much does faster memory help the new AMD APUs?Memory speed is not a factor that the average gamer thinks about when building their PC. For the most part, memory performance hasn't had much of an effect on modern processors running high-speed memory such as DDR3 and DDR4.With the launch of AMD's Ryzen processors, last year emerged. By running Ryzen processors with higher frequency and lower latency memory, users should see significant performance improvements, especially in 1080p gaming scenarios.However, the Ryzen processors are not the only ones to exhibit this behavior.Gaming on integrated GPUs is a perfect example of a memory starved situation. Take for instance the new AMD Ryzen 5 2400G and it's Vega-based GPU cores. In a full Vega 56 or 64 situation, these Vega cores utilize blazingly fast HBM 2.0 memory. However, due to constraints such as die space and cost, this processor does not integrate HBM.Instead, both the CPU portion and the graphics portion of the APU must both depend on the same pool of DDR4 system memory.

Uncheck the Automatically manage paging file size for all drives. Select the drive you would like to. AMD's answer to Ryzen performance problems is the Ryzen Balanced power plan for Windows 10, which promises to boost speed by up to 21 percent.
DDR4 is significantly slower than memory traditionally found on graphics cards such as GDDR5 or HBM. As a result, APU performance is usually memory limited to some extent., however with the launch of the new, we decided to take another look at this topic.For our testing, we are running the Ryzen 5 2400G at three different memory speeds, 2400 MHz, 2933 MHz, and 3200 MHz. While the maximum supported JEDEC memory standard for the R5 2400G is 2933, the memory provided by AMD for our processor review will support overclocking to 3200MHz just fine.
Synthetic Benchmarks. Historically, we've seen reasonably for AMD APUs for gaming. This doesn't change with the new Ryzen and Vega-based APUs.
Increased baseline memory compatibility to DDR-2933 with the Raven Ridge platform provides nice advantages in allowing all users to achieve higher memory clocks without having to overclock RAM and depend on motherboard compatibility with certain memory speeds.We also tested allocating additional memory to the Ryzen part within the BIOS. Going from the default allocation of 1GB to the highest available on 2GB saw no performance advantage.
It's clear that the Raven Ridge platform is able to allocate additional system memory as needed while gaming. However, allocating more memory in the BIOS can be useful for games that do checks for video memory either at the time of launching the executable, or when enabling higher visual quality settings.Currently, with highly inflated prices for all DDR4 memory, a 2x8GB kit of DDR4-2400 memory will., you can get a kit of the same capacity that will support DDR4-3200. For users looking to game on the integrated GPU of the Ryzen 3 2200G or Ryzen 5 2400G, it seems like a no-brainer to opt for the faster memory.
We were definitely not tryingWe were definitely not trying to show any product in any kind of specific light. I believed at the time, and still stand by, that testing everything at 2400 MHz was the right thing to do.
We wanted to include memory scaling in the first story, just ran out of time. This follow-up was the best option for us.Memory pricing changes, and we can't be expected to adjust for that on-the-fly 100% of the time.I think our review and thoughts and opinions on the new Ryzen with Vega graphics were incredibly positive. Gee dude, troll much?
At noGee dude, troll much? At no time in the many years of reading this sight has Ryan and his crew done anything but credible work. If they make a mistake they own it. If they run out of time, you might want to look at whether there’s competition to write about the same topic.You hammer on “its only $20 difference when thats not the point at all.

Its about the time they have to test and get things written so we, the reader they serve (quite well imo)can get the info and make the decisions on whether to try out the new stuff. In PCPer’s defense, theIn PCPer’s defense, the majority of truly BUDGET builders and 100% of OEMs are not going to spend $20 extra on faster RAM. Most people won’t even overclock. Using stock speeds and bottom-of-the-barrel RAM is going to be the most realistic scenario for the 2200G/2400G. It’s an appropriate first impression.That $20 can be saved for later and go toward a new/used dGPU later down the road. In the time between now and then, they have a perfectly decent 720p/1080p gaming rig or HTPC. Maybe next generation on theMaybe next generation on the lower end APUs AMD could add some eDRAM on die for the GPU and enable the Vega HBCC to use that eDRAM as HBC in a similar manner to what the HBCC does with HBM2 as HBC that is used on the discrete Vega variants.It also looks like Vega’s L2 cache and that reworking of Vega’s L2 cache with respect to the GPU’s raster back end and other GPU functional blocks has helped Vgea perform much better than previous GCN generation integrated graphics.
But AMD needs to think about eDRAM on the lower end APUs and HBM2 for some future high end APUs so Vega’s HPCC/HBC IP can benefit APUs also.Is 12nm going to be eventually used all of AMD’s APUs like it will be for the Ryzen CPU only refresh SKUs or will AMD just wait for 7nm to update its line of Zen/Vega APUs.AMD’s APU product stack for at least the next several months is finally complete as far as there being Zen/Vega mobile and desktop APU variants availabe finally from AMD. But the 2200G/2400G desktop variants are directly derived from the mobile variants so maybe at 12nm AMD will have some sort of refresh APUs or maybe just one new desktop APU variant at 12nm with a bit larger Vega nCU counts and some sort of extra GPU cache level for its integrated mobile Vega HBCC to use as HBC.Now comes the process of getting all the Firmware/Driver and Gaming software tweaked for Raven Ridge and that includes testing any games that will be making use of Vega’s FP16(Packed math) and Explicit Primitive Shaders, and orher new Vega IP. With Vega’s HBCC/HBC IP on hold for APUs until AMD can get either eDRAM or HBM2 for Vega’s HBCC to use as HBC.Faster memory is always a good thing to have for Mobile CPU/Integrated Graphics combo SKUs and eDRAM can be of help also until the HBM2 ecosystem and econony of scale takes hold at some future time and HBM2 can be used on mobile and desktop Zen/Vega products also. This clearly should’ve beenThis clearly should’ve been in the original review, the 10-15% uplift could’ve made it look better vs the 1030 and showed us the best case scenario for this APU. This article is welcomed for the “record” but is very thin and doesn’t give us the complete picture.
Where is the analysis? No memory timings, no max memory speed achievable(stable/bench only, ddr4-3333 or higher perhaps?), no overclocking GPU? Also in general what about underclocking? Ryan I come here to be informed and dazzled with charts and data(like allen does with ssds) not this half-assed quickly done article with little to no analysis. Is it that y’all only save in-depth analysis to make AMD look bad a la the frame-pacing saga?. Overclocking the gpu wouldOverclocking the gpu would have been nice since Ive seen some reviews go up past 1400mhz with ease.Just tested my 2200G with the igpu overclocked to 1600mhz at 1.25v.

Which is to try and convince people that the.only.
memory that works ok with these APUs is 16GB of low latency 3200 memory that costs well over $200.However, the truth is that to acheive 90+% of their gaming performance all you need is 8GB of CL15 2933 (2x4GB sticks)and a bit of iGPU overclocking.That memory will only cost you $90-100. So you can understand why shills/Intel PR mouthpieces don’t want people to realize this.
