AMD Ryzen 5 2400G Smokes Core i5-8400 at iGPU Performance

AMD is pinning a lot of hopes on its upcoming Ryzen 2000G "Raven Ridge" desktop APU family, which combine a quad-core "Zen" CPU with a larger-than-expected integrated GPU based on the latest "Vega" architecture. While Intel's iGPU design focus for its "Coffee Lake-S" processors continues to be hardware-accelerated 4K video playback, and non-gaming tasks; AMD promises a more wholesome solution. The integrated Radeon Vega 11 graphics of the Ryzen 5 2400G features 11 "Vega" NGCUs (next-generation compute units), which translates to 704 stream processors, 44 TMUs (@ 4 TMUs per NGCU), 8 or 16 ROPs, and a bandwidth-rich pathway to the APU's dual-channel DDR4-2933 capable IMC, thanks to AMD's new Infinity Fabric interconnect.

In its pre-launch press-deck for the Ryzen 3 2200G and Ryzen 5 2400G, AMD did the obvious - comparing a similarly priced Intel Core i5-8400 six-core processor (MSRP: $189) with its faster Ryzen 5 2400G (MSRP: $169.99) at gaming, highlighting its products key promise - enabling 1080p gaming with many of the newer AAA titles. In AMD's testing, the Radeon Vega 11 iGPU keeps frame-rates well above 30 fps at 1080p. In key popular titles such as "Battlefield 1," the frame-rates cross 50 fps, titles like "Overwatch" and "Rocket League" are almost that fast. "Skyrim" approaches 96 fps, while "The Witcher 3" stays barely above 30 fps. The i5-8400 with its UHD 620 graphics barely touches the 30 fps mark in any of the games, at 1080p. Even taking into account AMD's marketing hyperbole, the Radeon Vega 11 seems capable of running most eSports titles at resolutions above 1600 x 900, which should particularly interest iCafes and gamers on a shoestring budget.

In later news an i5 smokes a celeron in cpu performance.

Those scores are not bad however would be curious the settings.

The main issue with the 2400G is lack of support for high-frequency RAM. The IGPU is gonna be bandwidth-constrained with 2933MHz RAM.

For those of us who are casual gamers and/or Indie gamers, the 2400G should be an excellent choice. I still think Infinity Fabric is ruining this chip just like it's ruined the Ryzen CPUs.

Infinity Fabric lets you have your full x16 PCIe slot bandwidth without disabling the iGPU.

I would love to see (once the apu is released) a comparison between 2400G and an equally priced intel+nV combo.

How so? And even if it does that, I'm sure there are other workarounds to have full 16x bandwidth without disabling the IGPU. Infinity Fabric surrounds a 4-core Ryzen Module making all communication between the CPU cores and the uncore (L3 cache, memory controller, etc.) significantly slower.

These might launch at exactly the right time. Slightly better than an RX 550, and it comes with a CPU (Remember RX 550's are almost $150 now).

AMD should make a 1536-SP APU as well so people can actually build gaming PC's in 2018 :D

Looking at GPU prices, this might help gamers trying to build new PC through these bleak desperate times.

"Infinity Fabric Ruined Ryzen"

LOL ok. I hope you don't have any positions of power at a technology company. WOW...

At $190, I'm not sure what discrete NV card you could buy after the Intel CPU is factored in. I think AMD has the edge down at this end.

That's the official minimum supported RAM speed I believe. Motherboards can add support for MUCH faster RAM, although the target audience for this APU likely won't buy anything faster than 3200 anyway.

Um, nothing has ruined Ryzen, Ryzen is great. :)

Slower than what, exactly? And where is your source to back up this claim? Also, the L3 cache is part of the CCX, and AFAIK, doesn't use the Infinity Fabric bus to communicate with the CPU cores.

As far as I've seen they said one should be able to do 3400 mhz memory on these apu's while 2933 is SUPPORTED!
7700K got 2400mhz memory support and run at 3800 mhz and sometimes above.

So I think we safely can guess 3200mhz+ as ryzen 1700,1700x etc. was supporting 2666mhz and does 3400 mhz.

What's so bad about sub 3000Mhz memory? especially these days? a good, tight 2666-2933 can squeeze pretty much everything outta these chips.

I would sin a bit and say that for many users these days, this just wouldn't cut it even for "light" esports who need high FPS with low settings.

I really really wanna see a 95W chip that has 4C\8T and a much beefier 14-16 cluster GPU

I hope there will not be problems to connect igp to main video card in bios like i haw.

Good results for graphics, let see some CPU results as well

I checked on newegg, as soon as wrote that, and you can get a KBL Pentium and a GT1030 for the same money, but have no idea how those parts perform

GT 1030 is pretty tough for its footprint. Problem in this case though is the CPU horse power you get from the 2400G compered to it.

List of people who buy any Intel CPU for it's integrated graphics to game on them. You use the iGPU when you don't have choice , no one really goes out of their way to game on them.

Worse , not by a huge amount but enough the render them useless.

If the iGPU were an IRIS, I'd wager the list would be extensive because it would put up a decent fight. But hey, management choices, I guess :ohwell:

That's exactly why. Why compere an APU basically, to a production-dGPU gaming oriented hexa-core CPU. Doesn't make much sense.

Absolutely. I use a 5775C in one of my PCs and it suprises me how powerful this thing is. This chip came out almost 3 years ago. Give its iGPU an extra 50-60% performance and you get some nasty results.
