Following our in-depth Ryzen VR benchmark (R7 1700 vs. i7-7700K with the Rift + Vive), we immediately began compiling results for the concurrent R5 test efforts by GN Sr. Editor Patrick Lathan. Working together, we were able to knock-out the VR benchmarks (check those out here – some cool data), Ryzen Revisit piece, and today’s R5 reviews.
Both the R5 1600X ($250) and R5 1500X ($190) CPUs are in for review today, primarily matched against the Intel i5-7500 and i5-7600K. For comparison reasons, we have still included other CPUs on the bench – notably the i7-7700K and R7 1700, just to give an understanding of what the extra ~$70-$130 gets.
For anyone who hasn’t checked in on our content since the initial Ryzen reviews, we’d strongly encourage checking the Ryzen Revisit piece for a better understanding of how the scene has changed since launch. That revisit looks at Windows updates (and debunks some myths), EFI updates, and memory overclocking impact on Ryzen performance.
Although we have rerun the R7 gaming benchmarks with higher memory frequency (thanks to GSkill and Geil for providing B-die kits), we have not yet rerun them in synthetic tests. The 2933MHz frequency, as a reminder, was a hard limitation on our test platforms in the initial round of R7 reviews.
We will be including that data (albeit truncated) in our new tests, alongside Intel retests for the same games. For now, though, we’re reviewing the R5 1600X and R5 1500X CPUs in the Ryzen family, priced at $250 and $190, respectively.
This content marks the beginning of our in-depth VR testing efforts, part of an ongoing test pattern that hopes to determine distinct advantages and disadvantages on today’s hardware. VR hasn’t been a high-performance content topic for us, but we believe it’s an important one for this release of Kaby Lake & Ryzen CPUs: Both brands have boasted high VR performance, “VR Ready” tags, and other marketing that hasn’t been validated – mostly because it’s hard to do so. We’re leveraging a hardware capture rig to intercept frames to the headsets, FCAT VR, and a suite of five games across the Oculus Rift & HTC Vive to benchmark the R7 1700 vs. i7-7700K. This testing includes benchmarks at stock and overclocked configurations, totaling four devices under test (DUT) across two headsets and five games. Although this is “just” 20 total tests (with multiple passes), the process takes significantly longer than testing our entire suite of GPUs. Executing 20 of these VR benchmarks, ignoring parity tests, takes several days. We could do the same count for a GPU suite and have it done in a day.
VR benchmarking is hard, as it turns out, and there are a number of imperfections in any existing test methodology for VR. We’ve got a good solution to testing that has proven reliable, but in no way do we claim that perfect. Fortunately, by combining hardware and software capture, we’re able to validate numbers for each test pass. Using multiple test passes over the past five months of working with FCAT VR, we’ve also been able to build-up a database that gives us a clear margin of error; to this end, we’ve added error bars to the bar graphs to help illustrate when results are within usual variance.
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.
This first revisit to Ryzen’s performance comes earlier than most, given the tempestuous environment surrounding AMD’s latest uarch. In the past weeks, we’ve seen claims that Windows updates promise a significant boon to Ryzen performance, as has also been said of memory overclocking, and we were previously instructed that EFI updates alone should bolster performance. Perhaps not unrelated, game updates to major titles could have potentially impacted performance, amounting to a significant number of variables for a revisit.
Today’s content piece aims to isolate each of these items as much as reasonable – not all can be isolated, like game updates – to better determine the performance impact from the individual changes and updates. We’ll then progress cumulatively through charts as updates are applied. Our final set of charts will contain Windows version bxxx.970, version 1002 EFI on the CH6, and memory overclocking efforts.
Benchmarking Mass Effect: Andromeda immediately revealed a few considerations for our finalized testing. Frametimes, for instance, were markedly lower on the first test pass. The game also prides itself in casting players into a variety of environs, including ship interiors, planet surfaces of varying geometric complexity (generally simpler), and space stations with high poly density. Given all these gameplay options, we prefaced our final benchmarking with an extensive study period to research the game’s performance in various areas, then determine which area best represented the whole experience.
Our Mass Effect: Andromeda benchmark starts with definitions of settings (like framebuffer format), then goes through research, then the final benchmarks at 4K, 1440p, and 1080p.
Corsair, NZXT, Thermaltake, and EVGA closed-loop liquid coolers presently have no official AM4 retention kit support, leaving the companies exposed to questions from customers waiting to build Ryzen systems. This delay has affected the most popular coolers presently on the market, to include the Corsair H100iV2, H115i, NZXT X62/52/42, and new EVGA CLCs, but hasn’t affected all CLCs available. Some SIs, for instance, have blown throw stock of CoolIT-supplied CLCs from Corsair (like the H110i and H60), but haven’t been able to fill orders of units that use a four-screw mounting mechanism.
We have details for you on when your brackets will be available and on what caused the delays to begin with. This content contains several official comments and statements from the affected cooling manufacturers.
We’ve praised the R7 1700 ($330) for its mixed workload performance and overclocking capabilities at $330, and we’ve criticized the 1800X for its insignificant performance improvements (over the 1700) at $500. That leaves the R7 1700X ($400), positioned precariously between the two with a base clock of 3.4GHz, but the full 95W TDP of its 1800X sibling.
The 1700X performs as expected, given its flanks, landing between the R7 1700 and R7 1800X. All three are 8C/16T chips with the same CCX layout; refer back to our 1800X review for a more thorough description of the R7 CPU & Ryzen architecture. A quick comparison of basic stats reveals that the major advantage of the 1700X is a moderate increase in frequency, with additional XFR headroom as demarcated by the ‘X’ suffix. That said, our R7 1700 easily overclocked to a higher frequency than the native 1700X frequency, with no manual adjustment to voltage or EFI beyond the multiplier. The 1700X has a base clock of 3.4GHz and a boost clock of 3.8GHz, which theoretically means it could come close to the performance of our 3.9GHz 1700 straight out of the box while retaining the benefits of XFR (circumvented by overclocking).
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.
We moderate comments on a ~24~48 hour cycle. There will be some delay after submitting a comment.
