Ask GN 75 is an excellent episode. We had great questions for this one, including discussion on X370 vs. X470 benchmarking for Ryzen 2000 series CPUs (e.g. R7 2700X, R5 2600X), which we’ll get in to more detail with in the near future. As noted in the episode, we’re technically not under embargo for the Ryzen 2 CPUs, but we’re planning to hold our review until embargo lift out of respect for AMD’s decision to stop giving special treatment to some media, for this round. That said, we still talk a bit about X370 vs. X470 benchmarking in the Ask GN episode.
The other excellent topic pertained to receiving review samples and balancing hardware criticism – basically behind-the-scenes politics. Find the episode below:
This hardware news update looks into our original CTS Labs story, adding to the research by attempting to communicate with CTS Labs via their PR firm, Bevel PR. We also talk about leaked specifications for the R5 2600X, accidentally posted early to Amazon, and some other leaks on ASUS ROG X470 motherboards.
Minor news items include the loss of power at a Samsung plant, killing 60,000 wafers in the process, and nVidia’s real-time ray-tracing (RTX) demo from GDC.

The past week of hardware news has been peculiarly busy for this time of year, with a deluge of news posting toward the latter half of last week. For major stories, [H]ardOCP’s coverage of nVidia’s GPP agreements has undoubtedly garnered among the most attention in the news cycle, with additional stories of interest covering hacks to get Coffee Lake CPUs functional in Z170 and Z270 motherboards.
We’ve got a couple of minor news items – new liquid coolers, a mini-review of a chair – and a couple of game industry items, like Valve’s return to game development.
Find the written and filmed recaps below:
Even when using supposed “safe” voltages as a maximum input limit for overclocking via BIOS, it’s possible that the motherboard is feeding a significantly different voltage to the CPU. We’ve demonstrated this before, like when we talked about the Ultra Gaming’s Vdroop issues. The opposite side of Vdroop would be overvoltage, of course, and is also quite common. Inputting a value of 1.3V SOC, for instance, could yield a socket-side voltage measurement of ~1.4V. This difference is significant enough that you may exit territory of being “reasonably usable” and enter “will definitely degrade the IMC over time.”
But software measurements won’t help much, in this regard. HWINFO is good, AIDA also does well, but both are relying on the CPU sensors to deliver that information. The pin/pad resistances alone can cause that number to underreport in software, whereas measuring the back of the socket with a digital multimeter (DMM) could tell a very different story.
CPUs with integrated graphics always make memory interesting. Memory’s commoditization, ignoring recent price trends, has made it an item where you sort of pick what’s cheap and just buy it. With something like AMD’s Raven Ridge APUs, that memory choice could have a lot more impact than a budget gaming PC with a discrete GPU. We’ll be testing a handful of memory kits with the R5 2400G in today’s content, including single- versus dual-channel testing where all timings have been equalized. We’re also testing a few different motherboards with the same kit of memory, useful for determining how timings change between boards.
We’re splitting these benchmarks into two sections: First, we’ll show the impact of various memory kits on performance when tested on a Gigabyte Gaming K5 motherboard, and we’ll then move over to demonstrate how a few popular motherboards affect results when left to auto XMP timings. We are focusing on memory scalability performance today, with a baseline provided by the G4560 and R3 GT1030 tests we ran a week ago. We’ll get to APU overclocking in a future content piece. For single-channel testing, we’re benchmarking the best kit – the Trident Z CL14 3200MHz option – with one channel in operation.
Keep in mind that this is not a straight frequency comparison, e.g. not a 2400MHz vs. 3200MHz comparison. That’s because we’re changing timings along with the kits; basically, we’re looking at the whole picture, not just frequency scalability. The idea is to see how XMP with stock motherboard timings (where relevant) can impact performance, not just straight frequency with controls, as that is likely how users would be installing their systems.
We’ll show some of the memory/motherboard auto settings toward the end of the content.
Newegg’s sale of the new AMD Ryzen APUs, including the R3 2200G (that we’re reviewing now) and R5 2400G, posted the APUs above MSRP by roughly $20. The R5 2400G retailed on Newegg for $190, versus a $170 MSRP, and also landed the product significantly above Amazon’s competing pricing. We purchased APUs from both Newegg and Amazon, and paid less for the product from Amazon; of course, AMD (and other manufacturers) can’t control the prices of retailers – that’d actually be illegal – but they can certainly find ways to suggest a price. It is, after all, a manufacturer’s “suggested” retail price.
Today, we received the following note today from Newegg’s service account:
AMD's new Ryzen R5 2400G & R3 2200G APUs, codenamed "Raven Ridge," are available for sale ahead of official embargo lift. We've earmarked the pages, for anyone interested in getting a jump on the APUs. Note that, as always, we recommend waiting on reviews before purchase -- but we'll make it easier for you to find them. Our reviews of the 2200G & 2400G are pending arrival of parts, likely today/tomorrow, and we've pre-published some GT 1030 & low-end CPU testing. We'll fully finalize that content once the APUs are in.
For now, you can find the new APUs at these links:
Amazon R3 2200G listing (public - at time of posting, this was $99)
Amazon R5 2400G listing (private - will go live closer to 9AM EST)
Newegg R5 2400G listing (public - at time of posting, this was $190, a bit over MSRP)
Newegg R3 2200G listing (public - at time of posting, this was $130)
APU reviews have historically proven binary: Either it’s better to buy a dGPU and dirt-cheap CPU, or it’s actually a good deal. There is zero room for middle-ground in a market that’s targeting $150-$180 purchases. There’s no room to be wishy-washy, and no room for if/but/then arguments: It’s either better value than a dGPU + CPU, or it’s not worthwhile.
Preceding our impending Raven Ridge 2400G benchmarks, we decided to test the G4560 and R3 1200 with the best GPU money can buy – because it’s literally the only GPU you can buy right now. That’d be the GT 1030. Coupled with the G4560 (~$72), we land at ~$160 for both parts, depending on the momentary fluctuations of retailers. With the R3 1200, we land at about $180 for both. The 2400G is priced at $170, or thereabouts, and lands between the two.
(Note: The 2400G & 2200G appear to already be listed on retailers, despite the fact that, at time of writing, embargo is still on)
This hardware news round-up covers the past week in PC hardware, including information on AMD's Ryzen+Vega amalgam, CPU "shortage" sensationalism, Newegg commission changes, and more. As usual, our HW News series is written as a video, but we publish show notes alongside the video. We'll leave those below the embed.
The big news for the week was AMD's 2400G & 2200G APUs, which are due out on Monday of next week. The higher-end APU will be priced around $170, and will primarily compete with low-end CPU+GPU combinations (e.g. GT 1030 and low-end R3). Of course, the APUs also carve an interesting niche in a market with limited dGPU supply. Strategically, this is a good launch window for AMD APUs.
GamersNexus secured an early exclusive with the new Gigabyte Gaming 7 motherboard at CES 2018, equipped with what one could confidently assume is an AMD X470 chipset. Given information from AMD on launch timelines, it would also be reasonable to assume that the new motherboards can be expected for roughly April of this year, alongside AMD’s Ryzen CPU refresh. This is all information learned from AMD’s public data. As for the Gigabyte Gaming 7 motherboard, the first thing we noticed is that it has real heatsinks on the VRMs, and that it’s actually running what appears to be a higher-end configuration for what we would assume is the new Ryzen launch.
Starting with the heatsink, Gigabyte has taken pride in listening to media and community concerns about VRM heatsinks, and has now added an actual finstack atop its 10-phase Vcore VRM. To give an idea, we saw significant performance improvement on the EVGA X299 DARK motherboard with just the finned heatsinks, not even using the built-in fans. It’s upwards of 20 degrees Celsius improvement over the fat blocks, in some cases, since the blocks don’t provide any surface area.
