The new drivers mostly prime the RX 400 series cards for the upcoming Mass Effect launch—most demonstrably the RX 480 8GB, of which AMD notes a 12% performance increase when compared to drivers 17.3.1. Additionally, the drivers will add an “AMD optimized” tessellation profile.
The AMD Ryzen 5 series is set to continue AMD’s launch of its new Zen architecture, debuting earlier this month with the Ryzen 7 (R7) CPUs. Thus far, we’ve seen the release of the 1800X flagship, 1700X, and 1700 CPUs (the last of which being our option of choice). AMD’s subsequent launches will be focused on the R5 line, announced today, and a later-specified R3 line. We’re looking at a retail release date of April 11 for the R5 1400, R5 1500X, R5 1600, and R5 1600X CPUs; the R3 CPUs, meanwhile, are expected for availability in 2H17.
AMD hasn’t fully revealed all the technical details of these SKUs at this time. We know enough of the basics, but will have to wait for more information on how the CCXs are configured in 6C/12T scenarios.
Here’s a listing of prices, to get started:
Press embargo lifts today on a new mini-ITX case from BitFenix, the “subtle, yet remarkable” Portal. The “subtle” aspect might refer to the resemblance of the logo (and to some degree, the case), which appears to resemble the turrets from Valve’s video game of the same name, but that’s really a positive feature.
The Portal is, first and foremost, designed to house HTPCs. The space and thermal limitations of mini-ITX cases typically make it difficult to jam a real gaming PC inside, and the best chance for CPU cooling in this instance is a 120mm intake slot that can fit an AIO radiator. Still, Bitfenix does stress the versatility of the case: there are two 3.5”/2.5” bays and one 2.5” bay, so there should be enough for all the components of a decent gaming system. The 120mm is one of two fan mounts on the main chamber of the case: the other is a tiny 80mm fan (both contain fans by default), something we’re interested in noise testing later. Thermal tests will be interesting--although there’s very little space, the CPU is directly in the path of airflow and the GPU and PSU are thermally isolated, which is promising. Bitfenix describes the fans as “stable airflow for basic Office and Home Theater PCs.”
AMD yesterday released a community update with interesting assertions regarding thread scheduling, temperature reporting, Windows power plan issues, and SMT challenges.
According to AMD’s Robert Hallock, the company has found no indication that Windows 10 thread scheduling is operating improperly for Zen. This should be the final word in any argument that Microsoft thread scheduling issues are sabotaging Ryzen: they aren’t, as stated by AMD below:
“We have investigated reports alleging incorrect thread scheduling on the AMD Ryzen processor. Based on our findings, AMD believes that the Windows 10 thread scheduler is operating properly for ‘Zen,’ and we do not presently believe there is an issue with the scheduler adversely utilizing the logical and physical configurations of the architecture.
“As an extension of this investigation, we have also reviewed topology logs generated by the Sysinternals Coreinfo utility. We have determined that an outdated version of the application was responsible for originating the incorrect topology data that has been widely reported in the media. Coreinfo v3.31 (or later) will produce the correct results.”
MSI’s new-ish GS43 Phantom Pro laptop made an appearance at PAX East this weekend, where we’re presently RNG-ing some tear-downs and live benchmark demonstrations. Our first content piece discussed keyboard input latency testing, and our second piece – this one – will open up the Phantom Pro for a closer look.
As a quick side note, MSI does have “new” camo finish GTX 1060s, Z270 motherboards, and GE62 laptops. We show those briefly in the video, though it’s really not a focal point for today.
Logitech G’s recent history at PAX events includes real-time click latency testing on mice, something the company followed-up today with its keyboard latency testing. The new latency testing contraption is a lot simpler insofar as cost to build, with the BOM almost entirely consisting of an off-the-shelf Raspberry Pi 3, a plastic shell, and some wires. Logitech’s resulting platform enables us to test the response time from key presses between the new Logitech G Pro keyboard ($130) and a Razer Black Widow Tournament Edition keyboard. As with last year’s demonstration, Logitech is less focused on “beating” Razer and more focused on providing a proof of concept for their technology. Razer just happens to serve as a good benchmark, given the company’s proliferation in the PC market.
We already explained this amply in our AMD Ryzen R7 1800X review, primarily on pages 2 and 3 (but also throughout the article), but it's worth highlighting in video form for folks who prefer not to read articles. It's unfortunate that the test methodology and logistical pages were largely overlooked in the review -- most folks just jumped straight to the conclusion or gaming results, sadly -- so we are highlighting again, in video format, some of the things discussed on those pages.
As stated several times in this new video, we strongly encourage checking out the article. We are delaying our R7 1700 review by a day because of the addition of this video to our release schedule. There's not much more to say here, so we'll just embed that below:
NVidia just opened the floodgate on its GTX 1080 Ti video card, the Pascal-based mid-step between the GTX 1080 and GTX Titan X. The 1080 Ti opens up SMs over the GTX 1080, now totaling 28 SMs over the 1080’s 20 SMs, resulting in 3584 total FP32 CUDA cores on the GTX 1080 Ti. Simultaneous multiprocessor architecture remains the same – Pascal hasn’t changed, here – leaving us with primary changes in the memory subsystem.
The GTX 1080 Ti will host 11GB of GDDR5X memory – not HBM2 – with a speed of 11Gbps. This is boosted over the GTX 1080’s 10Gbps GDDR5X memory speeds, resultant of work done by memory supplier Micron to clean the signal. The heavy transition cluttering of early G5X iterations have been reduced, allowing a cleaner signal in the GDDR5X cells without data corruption concerns. We’ll have some news below on how this also relates to existing Pascal cards.
AMD was clear from the beginning of today’s Capsaicin and Cream event that it was not a Vega product launch (the only 100% new Vega news was that the GPU would be officially branded “Vega”), but demos of the previously mentioned technologies like high-bandwidth cache controller and rapid-packed math were shown.
After some brief discussion about exactly how much alcohol was consumed at last year’s afterparty, the Vega portion of the presentation covered three major points: HB Cache Controller, Rapid Packed Math, and Virtualization.
“Virtualization” in this context means the continued effort (by both AMD and NVIDIA) to make server-side gaming viable. AMD has partnered with LiquidSky and will be using Vega’s “Radeon Virtualized Encode” feature to make streaming games (hopefully) as latency-free as possible, though limitations on internet service still abound.
With the impending release of AMD Ryzen comes a wave of related product reveals. CyberPower is now offering preorders for several varieties of prebuilt PCs that take advantage of the new CPUs.
The four models below were described in CyberPower’s press release, and an additional four can be found on their website: the AMD Ryzen 7X Configurator, Mega Special III, Mega Special IV, and Winter Gaming Special II. Each of these configurations can be customized with alternate or additional parts, including “high-performance gaming memory, solid state drives, graphics cards, and gaming peripherals.” During the pre-sale, Corsair Hydro H60 AIO liquid coolers are included as a free upgrade, considering the limited launch-day support for AM4. CyberPower will in fact do a general “Pro OC” for a price, but there are plenty of free resources online for those interested.
