Final Thoughts

Our mission today was to determine if AMD's Ryzen 5 2400G could truly play games at 1920x1080 using low-quality settings. The answer is yes, though your mileage may vary depending on the title. Vega or not, we're still dealing with integrated graphics. So, the fact that this sub-$200 piece of highly integrated hardware gets us there at all is impressive. Raven Ridge-based processors aren't going to make you swear off add-in cards any time soon. But they do serve up playable frame rates, satisfying their mission in life. 

In comparison, the locked multipliers you find on Intel's low-cost CPUs hurt their value proposition among budget-minded enthusiasts. The company did make a half-hearted attempt to court power users with an unlocked K-series Core i3, but the thing is too expensive, no way around it. Moreover, it requires a Z-series chipset for overclocking and doesn't even include a heat sink. Hard pass.

Meanwhile, every AMD CPU is overclockable on B350 and X370 motherboards. Specifically, our Ryzen 5 2400G sample overclocked easily. With some extra time, we think we could have squeezed even more performance from it. That's particularly important because AMD needs the helping hands of enthusiasts to beat Intel in benchmarks it'd otherwise lose at stock settings.

AMD made some significant changes to Raven Ridge's architecture compared to the Zeppelin die. It reduced L3 cache capacity and latency, moved to a single-CCX layout, and bumped clock rates higher thanks to a refined 14nm+ manufacturing process. The result is a more competitive entry-level processor than anything we've seen from AMD before in our CPU-focused application workloads. Ryzen 5 2400G's ability to work on eight threads concurrently help it battle effectively, whether you're looking at highly parallelized workloads or simpler tasks like LAME encoding.

But the addition of AMD's Vega-based graphics engine is what everyone was holding their breath for. That combination of new Zen cores with modern 3D capabilities played well together throughout our benchmark suite at 1280x720. It also earned approving nods in most of the 1080p-based tests. The previous-generation A10-9700 and Intel's current UHD Graphics solution simply get slaughtered when they show up in the same charts.

We're impressed with Ryzen 5 2400G's overall performance story, especially in light of the chip's $170 price tag. It's a solid value paired with an inexpensive motherboard and a fast memory kit. As with APUs of the past, this processor gives you the ability to buy one chip without the expense of an add-in card. You can imagine the integration does some interesting things for builders and small form factors, too. Ryzen 5 2400G would be great in a mini-ITX box next to your TV.

AMD’s value pitch has long consisted of more cores for less money, and Raven Ridge brings that same philosophy to integrated graphics. The Ryzen 5 2400G is a surprisingly good processor for those looking for a capable gaming build on the lower end of today's pricing scale.

    Looking at Zeppelin and Raven dies side by side, proportionally, Raven seems to be spending a whole lot more die area on glue logic than Zeppelin did. Since the IGP takes the place of the second CCX, I seriously doubt its presence has anything to do with the removal of 8x PCIe lanes. Since PCIe x8 vs x16 still makes very little difference on modern GPUs where you're CPU-bound long before PCIe bandwidth becomes a significant concern, AMD likely figured that nearly nobody is going to pair a sufficiently powerful GPU with a 2200G/2400G for PCIe x8 to matter.

    1. Why did you use 32GB RAM for the Coffee Lake CPUs instead of the very same RAM used for the other CPUs?

    2. In the memory access tests I feel to see the relevance of comparing to higher teer Ryzen/ThreadRipper. Would rather see comparison to the four core Ryzens.

    3. Why not also test overclocking with the Stealth cooler? (Works okay for Ryzen 3!)

    4. Your comments about Coffee Lake on the last page:
    "Their locked multipliers ... hurt their value proposition...
    ... a half-hearted attempt to court power users with an unlocked K-series Core i3, ... it requires a Z-series chipset..."    As of right now all Coffee Lake CPUs require a Z-series chipset, so that's not an added cost for overclocking. I'd say a locked multiplier combined with the demand for a costly motherboard is even worse. (This is suppsed to change soon though.)

    Tom's must think highly of this APU to give it the Editor's Choice award. It seems to be your best bet for an extremely limited budget.

    I totally understand if you only have a few hundred dollars to build your PC with and you desperately want to get in on some master race action. That's the situation where the 2400G shines brightest. But the benchmarks show that games typically don't run well on this chip. They DO work under the right circumstances, but GTAV isn't as fun to play at low settings.

    Buying a pre-built PC from a boutique with a GeForce 1050Ti in it will make your experience noticeably better if you can swing the price.

    What most writers and critics of integrated graphics processors such as AMD's APU or Intel iGP all seem to forget, is not EVERYONE in the world has a disposable or discretionary income equal to that of the United States, Europe, Japan etc. Not everyone can afford bleeding edge gaming PC's or laptops. Food, housing and clothing must come first for 80% of the population of the world.

    An APU can grant anyone who can afford at least a decent basic APU the enjoyment of playing most computer games. The visual quality of these games may not be up to the arrogantly high standards of most western gamers, but then again these same folks who are happy to have an APU also can not barely afford a 750p crt monitor much less a 4k flat screen.

    This simple idea is huge not only for the laptop and pc market but especially game developers who can only expect to see an expansion of their Total Addressable Market. And that is good for everybody as broader markets help reduce the cost of development.

    This in fact was the whole point behind AMD's release of Mantle and Microsoft and The Kronos Group's release of DX12 and Vulkan respectively.

    Today's AMD APU has all of the power of a GPU Add In Board of not more than a several years back.

    Graphics still too weak , a card is still needed.

    That is not correct, afaik, not for A320 chipsets. It is for B350 and X370, though.

    "a card is still needed"

    You do realize that these CPUs have an integrated graphics chip as strong as a GT 1030, right? And that you are comparing a ~$90 GPU to a ~$220 GPU?

    If you can swing the price, grab a GTX 1080ti already, and let us mITX/poor/HTPC builders enjoy Witcher 3 in 1080p for a fraction of the price ;)

    When 1080p displays are available for as little as $80, there isn't much point in talking about 720p displays. I'm not even sure I can still buy one of those even if I wanted to unless I shopped used. (But then I could also shop for used 1080p displays and likely find one for less than $50.)

    The price of 4k TVs is coming down nicely, I periodically see some 40+" models with HDR listed for as little as $300, cheaper than most monitors beyond 1080p.

    Depends for who, not everyone is hell-bent on playing everything at 4k Ultra 120fps 0.1% lows. Once the early firmware/driver bugs get sorted out, it'll be good enough for people who aren't interested in shelling out ~$200 for a 1050/1050Ti alone or $300+ for anything beyond that. If your CPU+GPU budget is only $200, that only buys you a $100 CPU and GT1030 which is worse than Vega 11 stock.

    If my current PC had a catastrophic failure and I had to rebuild in a pinch, I'd probably go with the 2400G instead of paying a grossly inflated price for a 1050 or better.

    People come here expecting to find an overclockeable 4 core with a 1080-like performance for 160$. And a good cooler. I'd love to be so optimistic :D

    Summarizing: we are saving around 50-100$ for the same low-end performance. That's 25% to 40% cheaper. What are we complaining about?!? I'd be partying right now if that happened in high-end too!!! 300$ for a 1080...

    All those comments saying "too weak", or "isn't fun to play at low settings", seriously, travel around the globe or just open your mind, there's poor people in 90% of the world, do you think they'll buy a frakking 1080 and a 8700k?!?

    And there's even non-poor people that doesn't care about good graphics! Go figure!
    Otherwise, why there are pixel graphics games all over the place? Or unoptimized/breaking early access games??

    I have a high-end pc and still lower fps to minimum for competitive play, so I won't see any difference between a 1080Ti vs a 1070 (250 vs 170fps, who's gonna see that, my cat?!? No 'cause my monitor is not fast enough!).

    As a cyber cafe owner, I would love to replace my old A5400s to the lower R3.

    Except that the DDR4 sticks went crazy expensive over here. FML
