Steve started GamersNexus back when it was just a cool name, and now it's grown into an expansive website with an overwhelming amount of features. He recalls his first difficult decision with GN's direction: "I didn't know whether or not I wanted 'Gamers' to have a possessive apostrophe -- I mean, grammatically it should, but I didn't like it in the name. It was ugly. I also had people who were typing apostrophes into the address bar - sigh. It made sense to just leave it as 'Gamers.'"

First world problems, Steve. First world problems.

Prior to the Ryzen launch, we discovered an issue with GTA V testing that would cause high-speed CPUs of a particular variety to stutter when achieving high framerates. Our first video didn’t conclude with a root cause, but we now believe the game is running into engine constraints – present on other RAGE games – that trigger choppy behavior on those CPUs. Originally, we only saw this on the best i5s – older gen i5 CPUs were not affected, as they were not fast enough to exceed the framerate limiter in GTA V (~187FPS, or thereabouts), and so never encountered the stutters. The newest i5 CPUs, like the 7600K and 6600K, would post high framerates, but lose consistency in frametimes. As an end user, the solution would be (interestingly) to increase your graphics quality, resolution, or otherwise bring FPS to around the 120-165 mark.

Then Ryzen came out, and then Ryzen 5 came out. With R5, we encountered a few stutters in GTA V when SMT was enabled and when the CPU was operating under conditions permitting the CPU to achieve the same high framerates as Intel Core i5-7600K CPUs. To better illustrate, we can actually turn down graphics settings to a point of forcing framerates to the max on 4C/8T R5 CPUs, relinquishing some of the performance constraint, and then encounter hard stuttering. In short: A higher framerate overall would result in a much worse experience for the player, both on i5 and R5 CPUs. The 4C/8T R5 CPUs exhibited this same stutter performance (as i5 CPUs) most heavily when SMT was disabled, at which point we spit out a graph like this:


We’re reviewing the new MSI GTX 1080 Ti Gaming X card today, priced at $750 and positioned as one of the highest-performing gaming cards on the market. These tests will extensively look at thermals, given that that’s the primary differentiator between same-GPU video cards, and then look at gaming performance (in FPS) versus the Reference card and our Hybrid mod FE card. Part of our thermal testing will include performance analysis with and without a backplate. Noise levels are going to be the same as the last Twin Frozr card we tested, which can be found here.

This generation of GTX 1080 Ti cards has gone big. MSI’s Gaming X is already large, but the Gigabyte unit that we’re reviewing next is similarly big in the multi-slot department. The Gaming X uses MSI’s known twin-frozr cooler, with modifications to the underlying aluminum heatsink to increase surface area and fin density. Noise output is therefore identical to the noise output of previous Twin Frozr coolers we reviewed for the 10-series, including the GTX 1080 non-Ti Gaming X.

MSI ships the 1080 Ti Gaming X at three different frequencies, configurable through software: OC mode runs at 1683MHz boost and 1569MHz base, Gaming mode runs at 1657MHz boost and 1544MHz base, and silent mode runs at 1582 and 1480MHz.


We’ve been one of the most active in modding newly-launched GPUs with “hybrid” cooling solutions, and even recently began running thermal tests on VRM components alongside said mods. Before we ever did hybrid mods, NZXT launched its G10 bracket – back in 2013 – to tremendous success and adoption. That adoption died off over time, mostly due to new GPU launches that weren’t clear on compatibility, and NZXT eventually was met by competition from Corsair’s HG10.

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 week’s episode of Ask GN (#48!) talks CUDA core vs. Stream Processor differences at a top level, cooling suppliers, right to repair laws, and more.

The cooling supplier question is an interesting one: A user wondered what differences a manufacturer – someone like Corsair, NZXT, or others – might actually make when purchasing a semi-custom solution from a supplier. While it is possible to buy an off-the-shelf solution from the likes of Asetek, CoolIT, Apaltek, and others, the more common option is to customize the solution to some extent. This can be as low-level as instituting an entirely new PCB (see: Kraken series) or can be higher level, like tube length and pump flowrate.
