This is just a quick PSA.
We shot an off-the-cuff video about software misreporting Vega’s frequency, to the extent that a “1980MHz overclock” is possible under the misreported conditions. The entire point of the video was to bring awareness to a bug in either software or drivers – not to point blame at AMD – explicitly to ensure consumers understand that the numbers may be inaccurate. Some reviews even cited overclocks of “1980MHz,” but overlooked the fact that scaling ceases around the threshold where the reporting bugs out.
Following the initial rumors stemming from an Overclockers.co.uk post about Vega price soon changing, multiple AIB partners reached out to GamersNexus – and vice versa – to discuss the truth of the content. The post by Gibbo of Overclockers suggested that launch rebates and MDF would be expiring from AMD for Vega, which would drive pricing upward as retailers scramble to make a profit on the new GPU. Launch pricing of Vega 64 was supposed to be $500, but quickly shot to $600 USD in the wake of immediate inventory selling out. This is also why the packs exist – it enables AMD to “lower” the pricing of Vega by making return on other components.
In speaking with different sources from different companies that work with AMD, GamersNexus learned that “Gibbo is right” regarding the AMD rebate expiry and subsequent price jump. AMD purportedly provided the top retailers and etailers with a $499 price on Vega 64, coupling sale of the card with a rebate to reduce spend by retailers, and therefore use leverage to force the lower price. The $100 rebate from AMD is already expiring, hence the price jump by retailers who need return. Rebates were included as a means to encourage retailers to try to sell at the lower $499 price. With those expiring, leverage is gone and retailers/etailers return to their own price structure, as margins are exceptionally low on this product.
Tearing open the RX Vega 56 card revealed more of what we expected: A Vega Frontier Edition card, which is the same as Vega 64, which is the same as Vega 56. It seems as if AMD took the same PCB & VRM run and increased volume to apply to all these cards, thereby ensuring MOQ is met and theoretically lowering cost for all devices combined. That said, the price also increases in unnecessary ways for the likes of Vega 56, which has one of the most overkill VRMs a card of its ilk possibly could -- especially given the native current and power constraints enforced by BIOS. That said, we're working on power tables mods to bypass these constraints, despite the alleged Secure Boot compliance by AMD.
We posted a tear-down of the card earlier today, though it is much the same as the Vega: Frontier Edition -- and by "much the same," we mean "exactly the same." Though, to be fair, V56 does lack the TR6 & TR5 screws of FE.
Here's the tear-down:
Storing multiple terabytes of video content monthly is, obviously, a drive-intensive business -- particularly when using RAID for local editing scratch disks, a NAS for internal server access, and web remote backup. Rather than buy more drives and build a data library that is both impossible to manage and impossible to search, we decided to use our disks smarter and begin compressing broll as it falls into disuse. Deletion is the final step, at some point, but the compression is small enough as to be a non-concern right now. We're able to compress our broll anywhere from 50-86%, depending on what kind of content is contained therein, and do so with nearly 0 perceptible impact to content quality. All that's required is a processor with a lot of threads, as that's what we wrote our compression script to use, and some extra power each month.
Threadripper saw use recently in a temporary compression rig for us, as we wanted to try the CPU out in a real-world use case for our day-to-day operations. The effort can be seen below:
Computers have come a long way since their inception. Some of the first computers (built by the military) used electromagnets to calculate torpedo trajectories. Since then, computers have become almost incomprehensibly more powerful and accessible to the point at which the concept of virtual reality headsets aren’t even science fiction.
In gaming PCs, these power increases have often been used to ensure higher FPS, faster game mechanics, and more immersive graphics settings. Despite this, the computational power in modern PCs can be used for a variety of applications. Many uses such as design, communication, servers, etc. are well known, but one lesser known use is contributing to distributed computation programs such as BOINC and Folding@Home.
BOINC (Berkeley Open Infrastructure for Network Computing) and Folding@home (also sometimes referred to as FAH and F@H) are research programs that utilize distributed computing to provide researchers large amounts of computational power without the need of supercomputers. BOINC allows for users to support a variety of programs (including searching for extraterrestrial life, simulating molecular simulations, predicting the climate, etc.). In contrast, Folding@home is run by Stanford and is a singular program that simulates protein folding.
First we’ll discuss what distributed computing is (and its relation to traditional supercomputers), then we’ll cover some noteable projects we’re fond of.
Visiting AMD during the Threadripper announcement event gave us access to a live LN2-overclocking demonstration, where one of the early Threadripper CPUs hit 5.2GHz on LN2 and scored north of 4000 points in Cinebench. Overclocking was performed on two systems, one using an internal engineering sample motherboard and the other using an early ASRock board. LN2 pots will be made available by Der8auer and KINGPIN, though the LN2 pots used by AMD were custom-made for the task, given that the socket is completely new.
This episode of Ask GN (#56) revisits the topic of AMD's Temperature Control (TCTL) offset on Ryzen CPUs, aiming to help demystify why the company has elected to implement the feature on its consumer-grade CPUs. The topic was resurrected with thanks to Threadripper's imminent launch, just hours away, as the new TR CPUs also include a 27C TCTL offset. Alongside this, we talk Threadripper CPU die layout diagrams and our use of dry erase marker (yes, really), sensationalism and clickbait on YouTube, Peltier coolers, Ivy Bridge, and more.
For a separate update on what's going on behind the scenes, our Patreon backers may be happy to hear that we've just posted an update on the Patreon page. The update discusses major impending changes to our CPU testing procedure, as Threadripper's launch will be the last major CPU we cover for a little while. Well, a few weeks, at least. That'll give us some time to rework our testing for next year, as our methods tend to remain in place for about a year at a time.
This week’s hardware news recap goes over some follow-up AMD coverage, closes the storyline on Corsair’s partial acquisition, and talks new products and industry news. We open with AMD RX Vega mining confirmations and talk about the “packs” – AMD’s discount bundling supposed to help get cards into the hands of gamers.
The RX Vega discussion is mostly to confirm an industry rumor: We’ve received reports from contacts at AIB partners that RX Vega will be capable of mining at 70MH/s, which is something around double current RX 580 numbers. This will lead to more limited supply of RX Vega cards, we’d suspect, but AMD’s been trying to plan for this with their “bundle packs” – purchasers can spend an extra $100 to get discounts. Unfortunately, nothing says those discounts must be spent, and an extra $100 isn’t going to stop miners who are used to paying 2x prices, anyway.
Show notes below.
Under guidelines by AMD that we could show Threadripper CPU installation and cooler installation, we figured it’d also be pertinent to show cooler coverage on TR and RAM clearance. These all fall under the “installation” bucket and normally wouldn’t get attention from us, but Threadripper’s uniquely sized socket with uniquely positioned dies demands more instruction.
Threadripper thermal compound & coldplate coverage has been a primary topic of discussion since we first showed motherboards at Computex. We’ve generally offered that, theoretically, coldplate coverage should be “fine” as long as the two Threadripper CPU dies are adequately covered by the coldplate. In order to determine once and for all whether Asetek coolers will cover the IHS appropriately, seeing as that’s what TR ships with, we mapped out the dies on one of our samples, then compared that to CLC thermal paste silk screens, coldplates, and applied thermal compound.
Fractal Design is responsible for the Fractal Define C, one of our top-preferred cases from the past year. The Define C is a stout, well-constructed enclosure with competitive acoustics damping (behind only the Pure Base 600, in our tests) and thought-out cable management. Now, at what feels to be the mid-point of an ongoing trend in the industry, Fractal has announced its introduction of the Fractal Define C TG and Fractal Define C Mini TG (the latter is a shrunken ITX version of the ATX Define C).
