AMD Ryzen 3 2200G and Ryzen 5 2400G:launched

AMD has officially launched its first Ryzen desktop processors with integrated graphics. The new AMD Ryzen 3 2200G and Ryzen 5 2400G are first models in a new Ryzen 2xxx generation and feature integrated Radeon Vega graphics processors. AMD hopes to target entry-level users and is promising smooth gaming experiences at full-HD in the latest games, using low to medium settings.

The Ryzen 3 2200G is priced at Rs. 7,290 + GST in India

The Ryzen 5 2400G is priced at Rs. 10,990 + GST in India

AMD claims a huge performance lead in graphics compared to Intel

The Ryzen 3 2200G has four physical cores without multi-threading, a base speed of 3.5GHz, and a boost speed of 3.7GHz. The Ryzen 3 2400G also has four cores but multi-threading is enabled allowing for eight threads. The base speed is 3.6GHz while the boost speed is 3.9GHz. In terms of graphics capabilities, the Ryzen 3 2200G has eight Radeon Vega compute units running at 1100MHz, while the Ryzen 5 2400G has eleven running at 1250MHz. Both models have 4MB of L3 cache, and officially support up to DDR4-2933 RAM. Both also have 65W TDP ratings and come with AMD’s Wraith Stealth cooler in the box. As with all Ryzen CPUs, these new models are unlocked and overclockable.

The company says that it has been able to leverage improvements to its foundry partner’s 14nm fabrication technology, allowing it to drive higher frequencies within the same voltage and temperature limits. There have also been improvements to the speed and latency of the cache memory, which should lead to better responsiveness in certain applications. The Precision Boost feature has also been updated to version 2.0. This uses AMD’s multiple sensors embedded through the Infinity Fabric interconnect of each CPU to adjust frequency dynamically as workloads change. The company now says that Precision Boost 2 is even more fine-grained and allows more cores to run at higher speeds more often.

AMD’S RYZEN 5 2400G IS A GREAT OPTION FOR A BUDGET GAMING PC

First, they give us AMD’s latest Zen CPU architecture (not counting next month’s Zen+) combined with AMD’s top Vega graphics architecture. But there’s far more going on than a simple cut-and-paste job.

I don’t have full overclocking results ready just yet, but on the CPU front, the chip is mostly tapped out—I encountered stability issues beyond 3.9GHz with the stock cooler on my sample. That’s still potentially eight percent faster than stock, but nothing really noteworthy. The GPU is a different matter, with potential overclocks of around 20-25 percent being reported. I’ve encountered stability issues in general on my test system (I blame it on the early BIOS and firmware, and/or the DDR4-3200 CL14 RAM I’ve been running), but pushing the GPU core from the stock 1250MHz to 1500MHz or more seems feasible. I’ll update the article with additional overclocking results later this week.

On the CPU side of things, the first batch of Ryzen processors all used the same dual CCX (CPU Complex) design, with Threadripper going so far as to include two of those chips on a single package. (Technically there are four chips on Threadripper, but two of the chips are apparently duds.) The Ryzen CCX consists of four CPU cores, each with 512K of L2 cache, and a shared 8MB L3 cache. On the previous quad-core implementations (Ryzen 3 1200/1300X and Ryzen 5 1400/1500X), each CCX ends up with two disabled cores, and depending on the product, half of the L3 cache may also be disabled. For the Ryzen APUs, there’s only a single CCX, and a maximum of 4MB of L3 cache. That simplifies some aspects of multi-core operation—there are no cross-CCX latencies to worry about—but the reduced L3 cache size may at times be a factor.

In place of the second CCX, AMD has included a nice little graphics solution. The Ryzen 5 2400G calls it “Vega 11,” which is a Vega core with 11 enabled CUs (Compute Units), each of which includes 64 streaming processors (aka GPU cores). 11 seems like an odd number, so there might be another CU disabled, but AMD didn’t comment on this. The desktop currently only has a Vega 10 solution, but the ‘Vega 11’ in an APU is a completely different beast. The big change is that there’s no dedicated graphics memory—HBM2 or otherwise—and that’s going to take a toll on performance. But the Vega 11 does bring along all the other new Vega architecture features, like rapid packed math (aka FP16), the Draw Stream Binning Rasterizer, reworked geometry engine, and more. Interestingly, Intel is getting around this in its future Core + Vega M chips by opting to include 4GB of HBM2, which should prove substantially faster, but also far more expensive—and only for mobile solutions.

AMD provided the APUs, motherboard, and memory for the testing of the 2400G and 2200G. It’s worth pointing out that the RAM is extremely high-end relative to the rest of the system, and it’s designed to show the integrated graphics in the best possible light. Low-latency DDR4-2300 CL14 RAM isn’t something I’d normally pair with a budget processor, though for testing purposes I do normally use this level of memory. I’m going to retest the APUs with lower-spec DDR4-2400 RAM as well later this week, and I’ll update this article as appropriate with the additional results.

It’s important to note that, like all of AMD’s Ryzen processors to date, the Ryzen 5 2400G comes fully unlocked—on both the CPU and GPU sides of the fence. Not to spoil the performance results, but at stock the 2400G basically sounds the death knell for the existing Ryzen 5 1500X. It’s officially priced lower, it has slightly higher clockspeeds but half the L3 cache, and it hits a similar overclocking limit. Since both chips run in the same AM4 socket, there’s almost no reason to buy a 4-core Ryzen 5 solution going forward—or the Ryzen 3 CPUs either, for that matter.

I don’t have full overclocking results ready just yet, but on the CPU front, the chip is mostly tapped out—I encountered stability issues beyond 3.9GHz with the stock cooler on my sample. That’s still potentially eight percent faster than stock, but nothing really noteworthy. The GPU is a different matter, with potential overclocks of around 20-25 percent being reported. I’ve encountered stability issues in general on my test system (I blame it on the early BIOS and firmware, and/or the DDR4-3200 CL14 RAM I’ve been running), but pushing the GPU core from the stock 1250MHz to 1500MHz or more seems feasible. I’ll update the article with additional overclocking results later this week.

For purposes of testing, I’m limiting the CPUs in the charts to more modest processors—so you won’t find any Core i9 or Ryzen Threadripper results. That’s because the APUs are intended to compete in the budget and mainstream categories, and even the Core i7 and Ryzen 7 are here mainly as a point of reference. On the graphics front, I initially had problems getting a dedicated GPU to run in the mini-ITX motherboard (early firmware strikes again), and time constraints have prevented me from doing additional testing in a different host system. For now, I’ve limited the results to budget dedicated graphics cards at the GTX 1050 Ti/RX 560 level and below, and I’m working to generate some numbers for a Core i5-8400 using it’s HD Graphics 630 integrated GPU. I’ve also still got an AMD A10-7870K APU kicking around somewhere, so I’ll dust that off and see about generating some current numbers for it as well.

One thing that’s super cool about the test platform is that it’s extremely compact, and if you’re not interested in adding a discrete graphics card, which is sort of the point with an APU, a mini-ITX system is the perfect way to go. As a home theater PC (HTPC), the new Ryzen APUs deliver an awesome value and a great experience. AMD’s drivers have full support for all the common video formats, though I can’t say that I’ve done any testing with more esoteric videos—I’ll leave that to others. The entire system idles at just 21W, while under full load it peaks at about 90W. Needless to say, you don’t need any crazy cooling setup to keep things running within an acceptable temperature range, and the included Spire cooler that the Ryzen APUs ship with is more than sufficient.

The full list of test platforms and hardware is up and to the right, though the larger ATX boards and coolers are designed to compete in a different market segment. Initial testing of the Ryzen APUs used the MSI board with the 112PT5 revision BIOS. All test systems use fast DDR4-3200 memory to provide optimal performance, with M.2 NVMe SSD storage for the OS and applications, and games stored on a large 2TB SATA SSD as a secondary drive.

While I didn’t conduct any testing with a dedicated graphics card—normally I use a GeForce GTX 1080 Ti Founders Edition—given the similarity in performance between the APUs and the existing Ryzen 5 1500X and Ryzen 3 1300X, it’s a relatively safe bet that gaming performance with a dedicated GPU would be essentially the same. So for the purposes of the APUs, my primary focus is going to be on the integrated graphics performance.

Ryzen 5 2400G gaming performance

What do you get from 704 streaming processors clocked at 1250MHz, sharing system RAM with a 4-core/8-thread Ryzen CPU? It shouldn’t be too surprising to see that the graphics performance falls well short of the RX 560 4GB, which has a similar core clockspeed but sports 1024 cores and gets a dedicated 112GB/s of GDDR5 bandwidth. Performance in general will still be lower than even the RX 550 (512 cores and 112GB/s VRAM), thanks to the GDDR5 memory. By the numbers, the RX 560, which is a decidedly budget GPU, is about 65 percent faster than the Vega 11 graphics in the 2400G at 1080p medium, and a GTX 1050 is over 90 percent faster.

Frankly, I wanted more from AMD’s latest APU, though just looking at the paper specs I shouldn’t be surprised. The Vega architecture already underperforms in a lot of games compared to Nvidia’s Pascal offerings, and taking away the HBM2 certainly isn’t going to help. I really wish AMD could have stuffed in something closer to 16 CUs, and even better would have been some dedicated HBM2 for the APU, but then we’d likely be talking about a far more expensive part.

Ultimately, if you’re serious about playing the latest games, you should simply plan on buying some form of dedicated graphics. If your requirements are less demanding, lighter fare like Dota 2, CS:GO, Overwatch, and more are certainly playable, and in retrospect I probably should have targeted 1600×900 at low quality instead of 1080p medium. But if you’re on a budget—or if you were already thinking about buying a Ryzen 5 1500X or lower processor—the Ryzen 5 2400G adds in functional graphics with a slightly lower price. The Ryzen 5 APU can also work as a stopover while we wait for the insane GPU prices to correct and get back to something closer to normality.

Ryzen 5 2400G application performance

Shifting over to the non-gaming benchmarks, many of the tests show a virtual tie between the 2400G and the 1500X. There are a few anomalies, possibly due to the change in motherboard, or potentially updated firmware (I haven’t had a chance to fully retest all the other CPUs in the past several months). Here’s a look at our usual CPU-centric benchmarks.
