While we crank away at finalizing the review for the GTX 1080 Ti Gaming X, the Ryzen R5 CPUs, and some other products, we decided to run a PCB & VRM quality analysis of MSI’s card. The new GTX 1080 Ti Gaming X is another in a line of overbuilt VRMs, but interesting for a number of reasons (especially given the quality of this round’s reference VRM).
In our analysis of the PCB, we go over VRM design, overclocking potential, and power mods. The power mod section (toward the end of the video) discusses shunt shorting and how to trick the GPU into permitting a higher power throughput than natively allowed.

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.
On the heels of the media world referring to the Titan X (Pascal) as Titan XP – mostly to reduce confusion versus the previous Titan X – nVidia today announced its actual Titan Xp (lowercase ‘p,’ very important) successor to the Titan XP. Lest Titan X, Titan X, and Titan X be too confusing, we’ll be referring to these as Titan XM [Maxwell], Titan X (Pascal), and Titan Xp. We really should apologize to Nintendo for making fun of their naming scheme, as nVidia seems to now be in competition; next, we’ll have the New Titan Xp (early 2017).
Someone at nVidia is giddy over taking the world’s Titan XP name and changing it, we’re sure.
This was largely no surprise, given the stance that both the current administration and the newly appointed head of the FCC have adopted. The reversal of the rules traveled quick enough through the House and Senate that constituents had little chance to mitigate the overturn. We’ve covered this issue since it became public news, but in the event you’re not up to date, the now non-existent rules would have required ISPs to obtain clear consent before using data for advertising and other monetary purposes.
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.
The GPU market has been shaken up recently with the release of the nVidia GTX 1080 Ti and AMD’s inevitable Vega launch. Discounts on GTX 1080s and RX 400 series cards are available and widespread at this point, so we’ve highlighted some deals for those looking to upgrade or build a new PC in 2017.
“What the hell do you have to lose?”
That was the question that now President Trump asked the American people while campaigning. The answer? Internet privacy rights. That’s on top of the other regulations that, according to the current administration, stifle innovation and are harmful to business.
In a vote along party lines, House Republicans successfully voted to repeal privacy protections that were set to go in effect December 2017. All that is left is for President Trump to sign and approve the measure, and there is no reason to believe he will do otherwise. The conservative lawmakers controlling both the House and Senate were not alone in the crusade against digital rights—far from it. Several advertising trade associations both urged and applauded the action, as can be read in this statement. The Internet and Television Association, which represents many broadband providers, has praised the votes against the new rules. The Competitive Enterprise Institute has also staunchly opposed both narrow privacy regulations and net neutrality. For readers unfamiliar with the latter group, their espousal to limited government politics and “virtuous capitalism” is particularly laughable. As expected, they too applauded the deregulatory move.
Also worth mentioning is the chump change needed to sway lawmakers. Put another away: how much does privacy cost? Granted, buying Senators and Congress members isn’t exclusive to one party line or another, but one party responded remarkably well to it for this vote. This list details the contributions made to Senators supporting anti-privacy since 2012. Additionally, this list details how much money Congress members have received. While it seems easy to make an overly simplistic connection between money and votes—and neither party is above taking charitable donations from varying industries—it is worth noting that this vote was extremely partisan, and no champion of the bill offered to substantiate the reason this legislation is good for consumers, other than uttering elusive “anti-consumer” and “free market” platitudes. Similar regurgitant is being recited while plans to unwind the EPA, renewable energy, and climate change policies are being put in motion.
While this kind of regression in the digital age is alarming, there are other policies in place that protect consumers, albeit not to the same extent. The Telecommunications Act of 1996, the Cable Communications Policy Act of 1984, the Wiretap Act and the Electronic Communications Privacy Act all have privacy provisions relating to customer information. Specifically, Title II, Section 222 of the Telecommunications Act imposes privacy requirements; however, they are from 1996 and mostly apply to telecom services. The FCC vowed to write new internet-specific rules regarding how ISPs are to handle privacy. In a rare win for privacy advocates, the rules (which passed last year) explicitly detailed how ISPs were to store and handle data, and offer customers clear notices and opt-in requirements. Those rules are all but nullified now. If AT&T’s arguably unconstitutional surveillance business model is any indicator, archaic laws are not sufficient for modern internet access.
