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 today made available a power plan update which should change how the Balanced plan impacts Ryzen performance.
Problems with Windows preset power modes have been one of the biggest annoyances with Ryzen, and AMD has officially recommended the High Performance preset in the past in order to avoid subpar performance in benchmarks. This wasn’t a big deal from a testing point of view since High Performance mode effectively avoids all of these issues, but for everyday use, it was: High Performance mode doesn’t allow CPU frequency to drop when idle, and the additional power consumption can really hurt the long-term value of the system (it’s also just wasteful). Balanced mode does drop frequency, but it’s also been overly aggressive with core parking on Ryzen chips specifically, making it sub-optimal for use. We discussed what this looks like from a user’s point of view in our “Just Research” article, where frequency plots offer visualization for the impact of Performance vs. Balanced mode. The same article contains some FPS benchmarks between the two power modes.
AMD has made two major changes in this update. Quoting their statement:
Maintain residency in CPU p0 or p1 to give Zen full control over clocks and volts.
Disable core parking.
They specifically noted that Intel also fully disables core parking in the Balanced power plan. Our tests have always used High Performance mode for Ryzen platforms (except power tests), and our results will not be affected by this update.
We’ve received a ton of positive feedback on our i5-2500K revisit, and we’ve received a similar amount of questions about including overclocked i7-2600K numbers in our benchmark charts. The solution is obvious: a full 2600K revisit using our modern benchmark course. As demonstrated with the 2500K, old K-SKU Sandy Bridge CPUs had impressive overclocking capacity--partly thanks to a better thermal solution than what Intel offers today--but the stock i7-2600K regularly outperformed our 4.5GHz 2500K in some tests. Synthetic benchmarks and games like Watch Dogs 2, both of which take advantage of high thread counts, are included in those tests showing favor to the 2600K.1
Although we ended the 2500K review with the conclusion that now is a good time to start thinking about an upgrade, i7 CPUs are considered as more future-proof. Today, we’re testing that conception to see how it holds up to 2017’s test suite. With Ryzen 7 now fully released, considering 2600K owners are likely looking (price-wise) at a 7700K ($345) or 1700 ($330), it makes sense to revisit SNB one more time.
Note: For anyone who saw our recent Ryzen Revisit coverage, you know that there are some fairly important changes to Total War: Warhammer and Battlefield 1 that impacted Ryzen, and could also impact Intel. We have not fully retested our suite with these changes yet, and this content was written prior to the Ryzen revisit. Still, we’re including some updated numbers in here – but it’s not really the focus of the content, we’re more interested now in seeing how the i7-2600K performs in today’s games, especially with an overclock.
Radeon Software Crimson Edition version 17.4.1 is now live. Along with some bug fixes, the bulk of this release is additional VR support.
AMD is making good on their promise to support asynchronous reprojection for both Oculus Rift and SteamVR. Oculus’ “Asynchronous Spacewarp” is now usable on R9 Fury, 290 and 390 series cards, while SteamVR’s “Asynchronous Reprojection” is usable on RX 480 and 470s with Windows 10.
Blizzard announced in January that Overwatch had surpassed the 25 million player milestone, but despite being nearly a year old, there’s still no standardized way to benchmark the game. We’ve developed our own method instead, which we’re debuting with this GPU optimization guide.
Overwatch is an unusual title for us to benchmark. As a first person shooter, the priority for many players is on sustained high framerates rather than on overall graphical quality. Although Overwatch isn’t incredibly demanding (original recommended specs were a GTX 660 or a Radeon HD 7950), users with mid-range hardware might have a hard time staying above 60FPS at the highest presets. This Overwatch GPU optimization guide is for those users, with some graphics settings explanations straight from Blizzard to GN.
