The Ryzen 5 2400G is the top-end AMD Raven Ridge desktop APU to hit the market. This $169 chip is the primary to pair each the Ryzen CPU expertise with the crimson group’s Vega GPU . And, with the current GPU drought, a chip with this kind of gaming efficiency couldn’t have come at a greater time.
With whole AM4 compatibility Raven Ridge will work in our decide of the best AMD gaming motherboards.
The thought of this ‘Ryzen Processor with Radeon Vega Graphics’ is that it’s going to ship a modicum of gaming efficiency, with first rate processing capabilities, with out the necessity to have a discrete graphics card connected to your rig. That’s at all times been the overarching promise of the accelerated processor unit (APU), however that is the primary time we’ve seen a chip which is definitely able to delivering on it. And sure, ‘Ryzen Processor with Radeon Vega Graphics’ is how AMD are advertising and marketing the brand new Raven Ridge chips, quite than as an APU.
Previous APUs have been too compromised on each the GPU and CPU sides to actually compete, however with the fashionable Zen and Vega architectures in place that has positively modified.

AMD Ryzen 5 2400G specs
The Raven Ridge APU platform is constructed from these twin Zen and Vega architectural pillars, however we’re not speaking about two separate chips, as with Intel’s Kaby Lake G setup. Sitting beneath that unassuming heatspreader is a single slice of silicon with the 2 AMD applied sciences married collectively.
That marriage is constructed on the Infinity Fabric interconnect that mixes the GPU and CPU cores, in addition to the DDR4 reminiscence controllers, completely different multimedia and show silicon, and enter and output hub. The Infinity Fabric not solely ensures speedy communications between the related elements, but additionally permits the kind of finegrain energy management essential to handle the numerous calls for of the completely different components of the die.
This Ryzen 5 2400G chip basically sports activities the identical four-core, eight-thread design as low-end Ryzen 5 1400, however with some notable variations. First, AMD have chosen to make use of a single quad-core advanced (CCX) within the Raven Ridge chip, the place they used a twin CCX design for the 1400, the identical as they did for the eight-core Ryzen 7 1800X. For the 1400 they disabled two cores on every of the CCX, however that meant it retained a bigger quantity of L3 cache reminiscence than the brand new Raven Ridge chips.
For the 2400G they’ve gone for that solitary CCX, subsequently with half the L3 cache, partly as a result of it’s cheaper, but additionally due to the house constraints of getting to suit a full GPU into the identical die as properly. The decrease latency, born of not having to speak between two unbiased CCX, supposedly then offsets the relative lack of cache.
This top-end APU can also be aided by the actual fact it’s received a a lot greater base and increase clock spec. The three.9GHz prime pace of the 2400G is properly forward of the Ryzen 5 1400’s three.45GHz, and it’s additionally extra more likely to usually ship that peak clockspeed due to a redesign of the Precision Boost characteristic first launched with the inaugural Ryzen CPUs. Precision Boost is actually the characteristic that dynamically controls when the utmost increase clock can be utilized.
With the Ryzen 1000-series chips it solely comes into play when simply two cores are in use, however the second-gen model for the Ryzen 2000-series relies extra on the temperature and thermal headroom out there to the chip at any given time, permitting it to spice up even when all cores are in use. With the primary iteration, even video games which offloaded only a tiny quantity of labor throughout greater than two cores would relegate the chip to its base clockspeed, however that doesn’t occur now, making the brand new implementation much more game-friendly.
There are, nevertheless, fewer PCIe three.zero lanes within the 2400G in contrast with the primary gen Ryzen 5, with solely eight contained in the Raven Ridge design, in contrast with 16 within the 1400 CPU. That makes the 2400G cheaper and simpler to fabricate, however with a mainstream GPU having a x8 PCIe slot shouldn’t make any noticeable distinction when it comes to efficiency.
It is value noting that regardless of the Ryzen 2000 designation the Raven Ridge APUs aren’t utilizing the up to date 12nm Zen+ structure that’s set to reach with the AMD Ryzen 2 processors launching in April. All the efficiency enhancements then come from the up to date options quite than improved silicon.
But that’s simply the CPU specs, the graphics part of the Raven Ridge design is simply as vital, and the Vega GPU at its coronary heart packs extra cores inside than the cell variations that have been launched final yr. The Vega 11 GPU (named due to its 11 compute items) has 704 GCN cores inside it, operating at a speedy 1,250MHz. There’s no HBM2 reminiscence connected to this model of Vega, which implies it’s far simpler to supply in quantity and quite a bit cheaper, however except for that the characteristic set is similar as the larger discrete GPUs.
Now, in contrast with the four,096 GCN cores contained in the RX Vega 64 card that may appear fairly miserly compared, however that’s a singly 295W part, whereas this GPU is barely half of a a lot smaller 65W chip.
AMD Ryzen 5 2400G benchmarks
AMD Ryzen 5 2400G efficiency
On each CPU and GPU counts the efficiency of the Ryzen 5 2400G is quite spectacular. On one hand it’s a lot improved over the straight Ryzen 1000-series CPU it’s changing and on the opposite it has launched an unprecedented degree of built-in graphics silicon energy.
With 4 multi-threaded cores at its disposal there’s a variety of processing energy out there with this comparatively low-end APU. The Core i5 8400 is considered one of our favorite processors in the mean time, as is the the Ryzen 5 1600X, and each value a very good chunk greater than this 2400G but actually aren’t that far forward at inventory speeds.
The single-threaded tempo, due to the more-effective Precision Boost 2 characteristic, is at a good degree for a gaming processor. That means should you pair this chip with a high quality graphics card (robust to do proper now, I’ll admit) it’s nonetheless going to have the ability to preserve a discrete GPU operating at tempo. And with all eight threads able to performing on the three.9GHz increase clockspeed it’s received some severe processing chops too.
But when it comes to built-in graphics efficiency it’s gentle years forward of anything on this value bracket or scale. Admittedly the 1080p gaming body charges we’re getting out of the 2400G aren’t going to set the world alight, however these are set on the highest settings, with all of the post-processing bells and whistles, properly, ringing and whistling.
Knock the decision right down to 720p, nevertheless, and also you get real gaming efficiency from the likes of Hitman, Doom, Rise of the Tomb Raider, and specifically GTA V. The different three range between 59fps and 44fps at medium settings, however with GTA V the Vega GPU on the coronary heart of the 2400G is able to hitting 57fps on very excessive settings throughout the board at that decrease res. And by knocking GTA V right down to ‘normal’ throughout the board it’s even capable of hit 62fps on common at 1080p.
That’s severely spectacular from a system with no discrete GPU connected, and means constructing a low-power, tiny, funds gaming PC isn’t the trial or compromise it as soon as was.
Though the Raven Ridge chips do have a lot greater thermals than earlier Ryzen CPUs. That’s partly right down to the additional GPU silicon, but additionally as a result of AMD have opted for the cheaper, nonmetallic thermal interface materials (TIM) within the design.
The actual deal with with the top-end Raven Ridge APU, nevertheless, stems from the extent of overclocking I used to be capable of squeeze out of it. With regular multiplier overclocking, and a few even handed tweaking of the GPU clocks and voltages, I used to be capable of hit four.05GHz stably on the CPU facet and 1,500MHz on the Vega graphics silicon. At that pace you get a wholesome bump within the single-threaded gaming efficiency and it’ll give your graphics energy a little bit of a pace bump too.
But that’s not the entire story. Thanks to an accident of testing I used to be really capable of push the CPU a lot, a lot additional. Stability was a difficulty pushing past four.05GHz utilizing the multiplier, however by overclocking the BCLK, which usually sits at round 100MHz, I used to be capable of stand up to a totally secure four.55GHz.
AMD don’t usually allow BCLK overclocking on the Ryzen chips, it’s definitely not within the newest Ryzen Master overclocking utility, nor within the BIOS of our MSI B350I Pro AC, however the board nonetheless took it upon itself to routinely overclock to 112.52MHz should you put the system to sleep whereas already modestly overclocked.
What a pleasant board…
The four.55GHz overclock was equally secure with the Vega GPU overclocked to 1,500MHz, or with a discrete graphics card within the PCIe slot. At that degree you’re speaking about processor efficiency in extra of the highest Kaby Lake Core i7 7700Ok. Remember, this time final yr that was the quickest gaming CPU out there and round twice the value of what the 2400G is retailing for.
With each CPU and GPU overclocked to that extent – which additionally pushes the reminiscence as much as three,600MHz – the Raven Ridge APU was delivering 1080p gaming efficiency knocking across the 30fps degree the place it turns into really playable.
Now, it’s potential the weird sleepy time overclock may get patched out, and with pre-release BIOS updates we’ve been unable to duplicate it in boards the place you possibly can tweak the BCLK settings manually. But we’ll know for certain when launch BIOS patches are launched for the related boards.
AMD Ryzen 5 2400G verdict
AMD have launched their first desktop APU that makes real sense for avid gamers. Before now their APUs ended up utilizing hobbled processor and weakheart GPU cores, however by constructing on the dual pillars of the Ryzen and Vega applied sciences respectively AMD have managed to ship a single chip answer that may provide playable gaming efficiency with out the necessity for a discrete graphics card.
Obviously we’re not speaking about high-end PC energy right here. You’re not going to be powering your 1440p or 4K gaming panels at their native resolutions or refresh charges, however the degree of gaming you possibly can decide up at 720p, and typically even at 1080p, is severely spectacular.
There are caveats, nevertheless. You might want to knock again your recreation settings to accommodate the low energy GPU in place, and the assessment package that got here in from AMD to check the primary Raven Ridge desktop chips does value a fairly penny, so an affordable gaming rig this isn’t. All advised, our package runs to $617 (£578) and that’s earlier than you add in the price of a chassis, storage, and an influence provide.
The G.Skill reminiscence alone prices nearly $100 greater than the Ryzen 5 2400G itself, and the mini-ITX MSI board isn’t precisely a discount board. You will want good supporting elements, particularly on the reminiscence facet, to have the ability to get essentially the most out of the APU. Swapping the three,200MHz RAM for an 8GB 2,133MHz package has an enormous adverse impression on the efficiency of the platform.
But the 2400G nonetheless affords a implausible improve path for a gamer on a funds. Graphics playing cards are costly, and never simply due to cryptocurrency, value gouging, or manufacturing issues we’re seeing in the mean time. The GPU is commonly the costliest a part of any gaming construct, so having the ability to begin out your PC gaming life with out essentially having to purchase one proper in the beginning is a tantalising prospect for a lot of.
Building a rig across the 2400G will let you create a rig you possibly can recreation on right away, with the straightforward improve of dropping in a brand new graphics card when you possibly can afford one for an enormous body fee increase. The quad-core, eight-thread CPU on the coronary heart of prime Raven Ridge half are is nearly good as the highest Intel Kaby Lake chip from this time final yr. And, with our weird overclock in place you’re getting a piece of silicon that’s able to hitting virtually the identical degree as a $350 processor from 12 months in the past..
Even with out the BCLK overclock the tempo of the Ryzen 5 2400G is sufficient to ship nice gaming efficiency with a discrete GPU in place, even with that barely restricted x8 PCIe score. This is a good base-line chip in your new gaming rig, and with the assured longevity of the AM4 platform there’s a variety of upgrading potential for the longer term.
