AMD’s taken a page out of nVidia’s book, apparently, and nVidia probably took that page from Apple – or any number of other companies that elect to re-use product names. The new Radeon Pro Duo uses the same name as last year’s launch, but has updated the internals.
DDR4 prices continue to increase with no sign of slowing down, but this week Newegg has a sale on a 16GB kit of DDR4 from G.SKILL for $102. Sadly, this is a good deal in the current market. Non-flash storage devices have become cheaper as more of the market adopts SATA and M.2 SSDs, including a sale going on for a Seagate 4TB mechanical drive for $100. We have also highlighted a decent deal on a 750W PSU from Thermaltake, in addition to a discount on the Ryzen 1700 CPU.
The RX 580, as we learned in the review process, isn’t all that different from its origins in the RX 480. The primary difference is in voltage and frequency afforded to the GPU proper, with other changes manifesting in maturation of the process over the past year of manufacturing. This means most optimizations are relegated to power (when idle – not under load) and frequency headroom. Gains on the new cards are not from anything fancy – just driving more power through under load.
Still, we were curious as to whether AMD’s drivers would permit cross-RX series multi-GPU. We decided to throw an MSI RX 580 Gaming X and MSI RX 480 Gaming X into a configuration to get things close, then see what’d happen.
The short of it is that this works. There is no explicit inhibitor built in to forbid users from running CrossFire with RX 400 and RX 500 series cards, as long as you’re doing 470/570 or 480/580. The GPU is the same, and frequency will just be matched to the slowest card, for the most part.
We think this will be a common use case, too. It makes sense: If you’re a current owner of an RX 480 and have been considering CrossFire (though we didn’t necessarily recommend it in previous content), the RX 580 will make the most sense for a secondary GPU. Well, primary, really – but you get the idea. The RX 400 series cards will see EOL and cease production in short order, if not already, which means that prices will stagnate and then skyrocket. That’s just what retailers do. Buying a 580, then, makes far more sense if dying for a CrossFire configuration, and you could even move the 580 to the top slot for best performance in single-GPU scenarios.
Our third and final interview featuring Scott Wasson, current AMD RTG team member and former EIC of Tech Report, has just gone live with information on GPU architecture. This video focuses more on a handful of reader and viewer questions, pooled largely from our Patreon backer discord, with the big item being “GPU IPC.” Patreon backer “Streetguru” submitted the question, asking why a ~1300~1400MHz RX 480 could perform comparably to an ~1800MHz GTX 1060 card. It’s a good question – it’s easy to say “architecture,” but to learn more about the why aspect, we turned to Wasson.
The main event starts at 1:04, with some follow-up questions scattered throughout Wasson’s explanation. We talk about pipeline stage length and its impact on performance, wider versus narrower machines with frequencies that match, and voltage “spent” on each stage.
We’ll leave this content piece primarily to video, as Wasson does a good job to convey the information quickly.
AMD’s Polaris refresh primarily features a BIOS overhaul, which assists in power management during idle or low-load workloads, but also ships with natively higher clocks and additional overvoltage headroom. Technically, an RX 400-series card could be flashed to its 500-series counterpart, though we haven’t begun investigation into that just yet. The reasoning, though, is because the change between the two series is so small; this is not meant to be an upgrade for existing 400-series users, but an option for buyers in the market for a completely new system.
We’ve already reviewed the RX 580 line by opening up with our MSI RX 580 Gaming X review, a $245 card that competes closely with the EVGA GTX 1060 SSC ($250) alternative from nVidia. Performance was on-point to provide back-and-forth trades depending on games, with power draw boosted over the 400 series when under load, or lowered when idle. This review of the Gigabyte RX 570 4GB Aorus card benchmarks performance versus the RX 470, 480, 580, and GTX 1050 Ti and 1060 cards. We're looking at power consumption, thermals, and FPS.
There’s no new architecture to speak of here. Our RX 480 initial review from last year covers all relevant aspects of architecture for the RX 500 series; if you’re behind on Polaris (or it’s been a while) and need a refresher on what’s happening at a silicon level, check our initial RX 480 review.
It’s been a few months since our last PC build--in fact, it was published well before Ryzen was released. For our first post-Ryzen build, we’ve pulled together some of the components we liked best in testing to make an affordable ultrawide gaming machine. As we did in January, we pulled parts out of inventory and actually assembled and tested this PC to back up our recommendations--we’ll try to continue doing this going forward.
This gaming PC build is priced at just over $1000 -- about $1200, depending on rebates -- and is made for UltraWide 3440x1440 gaming. Our goal is to take reasonably affordable parts and show that UltraWide 1440p gaming is feasible, even while retaining high settings, without buying the most expensive GPUs and CPUs on the market. We’re only using parts in this build that we actually have, so that partially dictates cost (yes, you might be able to do some things cheaper -- like the motherboard), but it also means that we’ve had time to build, validate, and use the system in a real environment. In these early days of Ryzen as a new uarch, that’s important. We’ve done the hard work of troubleshooting a functional build. All you’d have to do is assemble it, configure BIOS, and go.
As a note: This build is also readily capable of production workloads. CUDA acceleration on the GTX 1070 will work well for Premiere renders, and the CPU thread-count will assist in CPU acceleration (like for streaming).
AMD’s got a new strategy: Don’t give anyone time to blink between product launches. The company’s been firing off round after round of products for the past month, starting with Ryzen 7, then Ryzen 5, and now Polaris Refresh. The product cannon will eventually be reloaded with Vega, but that’s not for today.
The RX 500 series officially arrives to market today, primarily carried in on the backs of the RX 580 and RX 570 Polaris 10 GPUs. From an architectural perspective, there’s nothing new – if you know Polaris and the RX 400 series, you know the RX 500 series. This is not an exciting, bombastic launch that requires delving into some unexplored arch; in fact, our original RX 480 review heavily detailed Polaris architecture, and that’s all relevant information to today’s RX 580 launch. If you’re not up to speed on Polaris, our review from last year is a good place to start (though the numbers are now out of date, the information is still accurate).
Both the RX 580 and RX 570 will be available as of this article’s publication. The RX 580 we’re reviewing should be listed here once retailer embargo lifts, with our RX 570 model posting here. Our RX 570 review goes live tomorrow. We’re spacing them out to allow for better per-card depth, having just come off of a series of 1080 Ti reviews (Xtreme, Gaming X).
Our Gigabyte GTX 1080 Ti Aorus Xtreme ($750) review brings us to look at one of the largest video cards in the 1080 Ti family, matching it well versus the MSI 1080 Ti Gaming X. Our tests today will look at the Aorus Xtreme GPU in thermals (most heavily), noise levels, gaming performance, and overclocking, with particular interest in the efficacy of Gigabyte’s copper insert in the backplate. The Gigabyte Aorus Xtreme is a heavyweight in all departments – size being one of them – and is priced at $750, matching the MSI Gaming X directly. A major point of differentiation is the bigger focus on RGB LEDs with Gigabyte’s model, though the three-fan design is also interesting from a thermal and noise perspective. We’ll look at that more on page 3.
We’ve already posted a tear-down of this card (and friend of the site ‘Buildzoid’ has posted his PCB analysis), but we’ll recap some of the PCB and cooler basics on this first page. The card uses a 3-fan cooler (with smaller fans than the Gaming X-type cards, but more of them) and large aluminum heatsink, ultimately taking up nearly 3 PCI-e slots. It’s the same GPU and memory underneath as all other GTX 1080 Ti cards, with differences primarily in the cooling and power management departments. Clock, of course, does have some pre-OC applied to help boost over the reference model. Gigabyte is shipping the Xtreme variant of the 1080 Ti at 1632/1746MHz (OC mode) or 1607/1721 (gaming mode), toggleable through software if not manually overclocking.
Today we have some more hardware sales for the weekend, including a SeaSonic 620W PSU, Gigabyte GTX 1070, and ASUS Z270 motherboard. An Intel NVMe SSD makes a special appearance in the listing. Sales are limited right now, particularly on GPUs given the precipitous launch cycle, but there are still a few active deals out there.
In light of both the House and Senate voting to reverse forthcoming privacy regulations, interest in privacy measures that can be taken by the end-user are no doubt piqued. While there is no comprehensive solution to end all privacy woes—outside of, you know, stringent privacy laws—there are a few different steps that can be taken. A VPN (Virtual Private Network) is the big one, although they come with a few of their own caveats. The Tor software offers the most ways to anonymize a user’s online presence and more, although it can be involved. Smaller actions include adjusting DNS settings and using the HTTPS Everywhere extension.
Read on, as we will delve into these in a bit more detail. This guide serves as a tutorial to setting up a VPN and protecting your privacy online.
