News this week talks about a few product launches -- some not coming to the West -- and new tech demos for PCIe Generation 5 and CXL. We also cover Intel's ongoing battles with marketing, the Threadripper 3 rumors of incompatibility with X399, and advancements in reverse-engineering silicon products.

The biggest news item this week came in the final hour of filming our weekly news show, and that's the Rockstar Games Red Dead Redemption 2 release for PC. It was a surprise announcement from Rockstar, but we now have a release date, information on updated graphics, and an eclectic mix of launch platforms listed for the PC launch of Red Dead 2. Additional news includes the ongoing lawsuit and countersuit between TSMC and GlobalFoundries, information on the Ryzen Surface products, Intel's X-series Cascade Lake pricing, Ryzen Pro 3000 CPUs, and the FCC's net neutrality rulings.
Hardware news headlines with some AMD 65W TDP parts whose specs were leaked to us in what appear to be official AMD documents, although we also have coverage of Intel's potential for another 14nm shortage, China's entrance into the DRAM market, and more. The DRAM market story is an interesting one, as the three incumbent players -- SK Hynix, Samsung, and Micron -- control functionally 100% of the market, with no new competition for a long time now. Memory supply is also rife with accusations of intellectual property theft and corporate espionage, something not likely to stop anytime soon.

Hardware news headlines with AMD's delay of the 3950X and the 7nm shortage that TSMC is experiencing. The shortage, it seems, is one of those "good problems" to have -- TSMC's 7nm process is so popular that it's struggling to keep up with demand, and so the fab is working to increase wafer output. Separately, news talks issues with iCUE software causing impact to FPS, somewhat unsurprisingly, in coincidental timing with the 465X iCUE launch.

Other than announcing our upcoming collaborative stream with overclocker Joe Stepongzi (Bearded Hardware), we're also talking Threadripper specification leaks, 6000MHz memory overclocking, RDNA 2 and Zen 3 roadmap information, and smaller items. For us, though, we're excited to announce that we're streaming some liquid nitrogen extreme overclocks with AMD parts this weekend. We haven't run both the 5700 XT and 3900X under liquid nitrogen at the same time, so we'll be doing that on Sunday (9/15) at 1PM Eastern Time (NYC time). On Saturday (9/14), we'll be streaming the efforts to overclock just the 3900X under liquid nitrogen. Joe Stepongzi, pro overclocker with a decade of experience in the 'sport,' will be joining us to help run the show.
This hardware news episode mostly focuses on alleged Threadripper documentation that we received through a leak, including discussion of the sTRX4 and sWRX8 processors that are listed in said document. The "4" and "8" are indicative of memory channel count, though we don't fully know what name or release date AMD intends to give these CPUs. AMD's Threadripper 3000 series CPUs will be competing with Intel in HEDT, where Intel is presently focusing effort for its next major release cycle. Beyond the Threadripper discussion, we also talk about Intel and AMD bickering with each other like children (I'll turn this car around right now!), Der8auer's survey, USB4 spec, and the Steam Hardware Survey.

Memory speed on Ryzen has always been a hot subject, with AMD’s 1000 and 2000 series CPUs responding favorably to fast memory while at the same time having difficulty getting past 3200MHz in Gen1. The new Ryzen 3000 chips officially support memory speeds up to 3200MHz and can reliably run kits up to 3600MHz, with extreme overclocks up to 5100MHz. For most people, this type of clock isn’t achievable, but frequencies in the range of 3200 to 4000MHz are done relatively easily, but then looser timings become a concern. Today, we’re benchmarking various memory kits at XMP settings, with Ryzen memory DRAM calculator, and with manual override overclocking. We’ll look at the trade-off of higher frequencies versus tighter timings to help establish the best memory solutions for Ryzen.
One of the biggest points to remember during all of this -- and any other memory testing published by other outlets -- is that motherboard matters almost more than the memory kit itself. Motherboards are responsible for most of the timings auto configured on memory kits, even when using XMP, as XMP can only store so much data per kit. The rest, including unsurfaced timings that the user never sees, are done during memory training by the motherboard. Motherboard manufacturers maintain a QVL (Qualified Vendor List) of kits tested and approved on each board, and we strongly encourage system builders to check these lists rather than just buying a random kit of memory. Motherboard makers will even tune timings for some kits, so there’s potentially a lot of performance lost by using mismatched boards and memory.
This week's hardware news has a litigation theme, including battles between GlobalFoundries and TSMC and AMD and the public. In the former, it's a fight over intellectual property and alleged infringements; in the latter, it's been resolved, and buyers of the Bulldozer CPUs affected can lay claim to $35 (unless a lot of people claim it, in which case it'll dilute further). Beyond that, we'll be talking RX 5700 stock, sales numbers, and Intel's banter with AMD.

Hardware news this week is largely focused on new product launches, or rumors thereof, with additional coverage of Intel's plans to launch 10nm Ice Lake CPUs in some capacity (for real, this time) by end of year. The XFX RX 5700 XT "THICC" was leaked -- yes, that's a real name -- and it's accompanied by other partner model cards coming out in the next week.

This is a quick and straightforward piece inspired by a Reddit post from about a week ago. The reddit post was itself a response to a video where a YouTuber claimed to be lowering temperatures and boosting performance on Ryzen 3000 CPUs by lowering the vcore value in BIOS; we never did catch the video, as it has since been retracted and followed-up by the creator and community with new information. Even though the original content was too good to be true, it was still based on a completely valid idea -- lowering voltage, 50% of the equation for power -- will theoretically reduce thermals and power load. The content ended up indirectly demonstrating some unique AMD Ryzen 3000 behaviors that we thought worth testing for ourselves. In this video, we’ll demonstrate how to know when undervolting is working versus not working, talk about the gains or losses, and get some hard numbers for the Master and Godlike motherboards.
