HW News - AMD CPU Surge in Steam Survey, SAM for Z490, Intel Rocket Lake
As the end of the year approaches, things remain busy as ever with yet more GPU launches, Cyberpunk 2077 coming out, and plenty of cooler reviews. However, we’ve managed to scrape a few interesting stories together, amidst all of the end-of-year content (GN’s included).
We have the most recent Steam Hardware Survey, which continues the trend of AMD snatching up CPU market share, but getting beaten 18 times in the top 20 GPU rankings. There’s also a minor update on Nvidia’s supply woes, as it relates to the RTX 30-series drought.
We also have a bit more to go over, as you’ll find the usual article and video embed below.
HW News - "X590" False Alarm, RTX 3070 Delays, Zen 3 Motherboard Updates
At GN, we’re slowly emerging from our RTX 30-series coma, where we’ve pushed our testing and coverage perhaps as far as we ever have. We’re getting ready to slow down for a week or so to revamp and improve processes internally and get ready to do it all again with Zen 3, RDNA2, and the RTX 3070.
As ever, there’s plenty to cover outside of our reviews and testing. This week, we have news regarding NVIDIA delaying the RTX 3070 launch window to the end of October in an effort to avoid the previous RTX 3080 and 3090 catastrophe. There’s also a credible rumor suggesting that Zen 3 will come in under the Ryzen 5000-series banner, which would probably be for the best, given how convoluted CPU naming is getting.
Elsewhere, we discuss Intel’s Omni-Path being resurrected under the new Cornelis Networks, leaked Windows XP source code, an interesting new HPE-Cray built supercomputer, and more. Check out the article and video embed below.
AMD Chipset Comparison: B550 Specs vs. X570, B450, X370, & Zen 3 Support (2020)Friday, 08 May 2020
In this content, we’re going to be breaking-down the AMD B550 vs. X570, B450, X470, X370, and A320 chipset specifications number-by-number. Our goal is to look at this purely from a facts-based angle of what the differences are, and those differences will include both numerical specification differences (number and type of lanes afforded) and forward or backwards compatibility differences. This includes the intent of the 500-series chipsets to support Zen 3 architecture (reminder: that’s not the same as Ryzen 4000 mobile, nor is it the same as Ryzen 3000 desktop), while the existing B450 and X470 boards are left to cap-out at Ryzen 3000 series (Zen 2) parts.
We have some additional discussion of the basics of naming, including CPU naming distinctions, in our video component that accompanies this article. You may get more information on the differences between AMD Zen generations and Ryzen generations in that content.
"E-ATX" Is A Lie: XL-ATX, E-ATX, ATX, EEB, and SSI-CEBSaturday, 28 March 2020
EATX is bullshit wannabe half-specification, not a real form factor. At least, not the way it’s being treated right now. It doesn’t mean anything. The name “EATX” implies a standard, but it’s not a standard, it’s a free-for-all. That’s not even getting into EE-ATX, or Enhanced Extended Advanced Technology eXtended, which is actually a name. Things would be a lot easier for everyone if motherboard manufacturers stuck to the dimensions of SSI-EEB without trying to wedge custom form factors in between, or correctly referred to 12”x10.5” boards as SSI-CEB, but that’d require actually trying to follow a spec. Then case manufacturers would have no reason to write “EATX (up to 11 inches)” in every single spec sheet for normal-sized mid towers, and customers would know at a glance exactly what they were getting. We’ve had a hell of a time lately trying to find cases that fit our “E-ATX” motherboards, which range in size from “basically ATX” to “doesn’t fit in any case that says it supports E-ATX, but is still called E-ATX.” We took that frustration and dug into the matter.
Other than technical discussion, we’ll also get the fun of unrolling the acronyms used everywhere in the industry, and talking about how stupid form factors like XL-ATX have three different sizes despite having one name, or how E-ATX has been split into “True E-ATX” and “Full Size E-ATX,” which also don’t mean anything to anyone.
HW News - [email protected] Faster Than 7 Supercomputers, Motherboard Sales Fall 30%
Our recap of hardware news for the past week follows-up on plans to RIP somebody -- but we're not sure who that should be just yet -- in a Folding @ Home points-chasing competition. To a similar tune, Folding @ Home has now surpassed the top 7 supercomputers in compute power totaled, something that NVIDIA, [email protected], and the PCMR sub-reddit all drove together. Other positive news has Razer turning production lines toward N95 mask production for Coronavirus/COVID-19 use in hospitals and elsewhere. Bad news includes hits to the economic side of computer hardware, with motherboard sales falling 30-50%.
Best Motherboard Sales for Black Friday & Cyber Monday (AMD AM4 Ryzen, Intel Z390)
We’ve covered a variety of sales this Black Friday, including a wide range of components like best monitor sales, best GPU and CPU sales, and an overall deal roundup. We’ve also written some guides that build upon a year of testing data, including our best CPUs of 2019, best cases of 2019, and best GPUs of 2019 round-ups.
Today, we’ll be focusing on the best motherboard discounts presently available on both Newegg and Amazon for both AMD and Intel. Remember, this isn’t a “best motherboard roundup,” but rather a best motherboard sales listing. You can reference our best Z390 boards video for Intel’s top-performing boards or our best motherboards for Ryzen 3000, and we have another of those on the way tonight. Every sale we list here is a motherboard that’s at least decent or recommended and that actually has a real discount, not just the fake markdowns that we see all the time. Some of these have individual reviews/analysis videos we’ve done that will be linked with them.
AMD X570 vs. X470, X370 Chipset Comparison, Lanes, Specs, & DifferencesFriday, 14 June 2019
AMD’s X570 chipset marks the arrival of some technology that was first deployed on Epyc, although that was done through the CPU as there isn’t a traditional chipset. With the shift to PCIe 4, X570 motherboards have grown more complex than X370 and X470, furthered by difficulties cooling the higher power consumption of X570. All of these changes mean that it’s time to compare the differences between X370, X470, and X570 motherboard chipsets, hopefully helping newcomers to Ryzen understand the changes.
The persistence of AMD’s AM4 socket, still slated for life through 2020, means that new CPUs are compatible with older chipsets (provided the motherboard makers update BIOS for detection). It also means that older CPUs (like the reduced price R5 2600X) are compatible with new motherboards, if you for some reason ended up with that combination. The only real downside, aside from potential cost of the latter option, is that new CPUs on old motherboards will mean no PCIe Gen4 support. AMD is disabling it in AGESA at launch, and unless a motherboard manufacturers finds the binary switch to flip in AGESA, it’ll be off for good. Realistically, this isn’t all that relevant: Most users will never touch the bandwidth of Gen4 for this round of products (in the future, maybe), and so the loss of running a new CPU on an old motherboard may be outweighed by the cost savings of keeping an already known-good board, provided the VRM is sufficient.
HW News - Intel PCIe 5 & DDR5 Push, 6GHz DDR4, & Huawei Loses ARM
Computex 2019 is next week -- a few days from now, technically -- and hardware news has been alight with PCIe 5.0 and DDR5 discussion for Intel platforms, Huawei's ban from the US, DDR4 overclocking close to 6GHz, and more. Intel's biggest news is certainly the PCIe 5 and DDR 5 discussion, which will be our leading story for today's news.

Intel TDP Investigation: Boards Violating Turbo Duration (Z390)Tuesday, 06 November 2018
Intel’s TDP has long been questioned, but this particular generation put the 95W TDP under fire as users noticed media outlets measuring power consumption at well over 100W on most boards. It isn’t uncommon to see the 9900K at 150W or more in some AVX workloads, like Blender, thus far-and-away exceeding the 95W number. Aside from TDP being an imperfect specification for power, there’s also a lot that isn’t understood about it – including by motherboard manufacturers, apparently. All manufacturers are exceeding Intel guidance for the Turbo boosting duration in some way, which is causing the uncharacteristically high power consumption that produces unfairly advantaged performance results. The other end of this is that the 9900K looks much hotter in some tests.
Optimized vs. Cheating: Z390 Motherboard BCLK ComparisonWednesday, 31 October 2018
We previously deep-dived on MCE (Multi-Core Enhancement) practices with the 8700K, revealing the performance variance that can occur when motherboard makers “cheat” results by boosting CPUs out of spec. MCE has become less of a problem with Z390 – namely because it is now disabled by default on all boards we’ve tested – but boosted BCLKs are the new issue.
If you think Cinebench is a reliable benchmark, we’ve got a histogram of all of our test results for the Intel i9-9900K at presumably stock settings:
(Yes, the scale starts at non-0 -- given a range of results of 1976 to 2300, we had to zoom-in on the axis for a better histogram view)
The scale is shrunken and non-0 as the results are so tightly clustered, but you can still see that we’re ranging from 1970 cb marks to 2300 cb marks, which is a massive range. That’s the difference between a heavily overclocked R7 2700 and an overclocked 7900X, except this is all on a single CPU. The only difference is that we used 5 different motherboards for these tests, along with a mix of auto, XMP, and MCE settings. The discussion today focuses on when it is considered “cheating” to modify CPU settings via BIOS without the user’s awareness of those changes. The most common change is to the base clock, where BIOS might report a value of 100.00, but actually produce a value of 100.8 or 100.9 on the CPU. This functionally pre-overclocks it, but does so in a way that is hard for most users to ever notice.
