NVidia’s Volta GV100 GPU and Tesla V100 Accelerator were revealed yesterday, delivering on a 2015 promise of Volta arrival by 2018. The initial DGX servers will ship by 3Q17, containing multiple V100 Accelerator cards at a cost of $150,000, with individual units priced at $18,000. These devices are obviously for enterprise, machine learning, and compute applications, but will inevitably work their way into gaming through subsequent V102 (or equivalent) chips. This is similar to the GP100 launch, where we get the Accelerator server-class card prior to consumer availability, which ultimately helps consumers by recuperating some of the initial R&D cost through major B2B sales.

Fractal’s Celsius S36 debuts alongside the company’s S24, coolers sized at 360mm and 240mm, respectively. The Celsius series uses an Asetek Gen5 pump, identical to the pump found on the EVGA CLC, NZXT X42/52/62, and Corsair H115i/H100iV2 coolers. This is a semi-custom Asetek solution that’s been loosely customized by Fractal Design, primarily focusing on the addition of G1/4” fittings (rad-side only), on-pump speed tuning, and an on-rad fan hub. It’s not as customized as, say, the NZXT Kraken series, but NZXT’s products also run more expensive. Fractal is looking at a launch price of $120 for the S36 that we’re reviewing today, and $110 for the S24.

Our focuses are on thermals and noise – not that you can focus on much else when talking coolers – with some new testing that looks at normalized noise output. We debuted this testing in our ASUS ROG Strix review and have carried it over to coolers.

Fractal’s coolers use 120mm fans that run a maximum RPM nearing 2000, with variable pump RPM from ~2000~3000. In our testing, though, it seemed a little simpler than that – pump RPM is based on liquid temp, and as we found in our 7700K review (the hottest CPU we've tested), liquid temp never really exceeds 30C. Given Fractal's curve, that means the pump stays at 2000RPM almost all the time. Rather than use software or suggest straight BIOS control – which we prefer – Fractal’s gone with a toggleable pump plate that switches into auto or PWM options. We’ve tested variable pump speeds in the past and haven’t found major differences in cooling efficacy, which is more heavily relegated to the fan spec and radiator size than anything else. This is more of a noise impact. We tested using the default, out-of-box “auto” setting, which kept our pump RPM fixed nearly perfectly at ~1960 throughout the tests (liquid temperature doesn't ramp up enough to push higher).


Fan speeds were manually controlled for the tests, though users could connect the fans to the on-rad hub. More on this in the conclusion.

Let’s get on with the testing, then run through the accessories and conclusion.

One of the most requested additions to our video card testing has been to normalize for noise. Several of you have emailed, tweeted, or tagged us on Reddit to ask for this type of testing, and so we started the process of re-testing some devices to build a database. The idea is to find fan RPM at a fixed dBA output – 40dBA, for example – and then test thermal performance when fans match that noise level. This doesn’t take into account the type of noise, e.g. frequency spectrum analysis, but it’s a good start to a new type of testing. And, honestly, most of these coolers sound about the same pitch/frequency (subjectively) with regard to frequency output.

The ASUS ROG Strix 1080 Ti review is our first to introduce normalized noise testing, and it’s an interesting card to start us off. We’ll talk more about that specific testing approach lower down.

Silverstone’s RL06 case is divided into four SKUs: SST-RL06BR and SST-RL06WS, with -W and -PRO versions of both. Our review sample is the SST-RL06WS-PRO ($75), which means it’s white with silver trim (WS) and comes with 3x 120mm white LED fans (PRO). BR is black with red trim, and -W is theoretically exactly the same case without the fancy fans, although there don’t appear to be any available anywhere right now.

The RL06 is a stripped-down case with serious airflow at a budget price. Today, we’re putting it on our bench against the nearby Corsair 270R, Be Quiet Pure Base 600, Fractal Define C, and other options we’ve tested recently. The RL06 is more airflow-focused than noise-focused, giving us something different to analyze than the past few case reviews.

This week’s hardware sales are scarce, but there are still some worthy ones. We found a fair price on an MSI GTX 1080 and an MSI RX 580 card, with some supporting deals on a pair of mechanical keyboards from Logitech and G.SKILL, if that is of interest.

Intel’s i3/i5/i7 and AMD’s R5/R7 CPUs are the big competitors in the PC gaming world, but they aren’t the only options out there: AMD released cheap but capable Athlon X4s in 2016, and in January of this year Intel released the 2C/4T Pentium G4560 ($70), a 14nm Kaby Lake processor for ~$64~$70. We didn’t fully review the older and (briefly) popular Pentium G3258, but it has showed up in Ask GN and individual benchmarks, so we were excited to do comprehensive testing on this modern iteration.

The G4560 lacks the feature that made the G3258 so popular: the ability to overclock. Buying a dirt-cheap dual-core processor and cranking the frequency up was enough for decent performance in limited-thread games, although the G3258 often suffers from extreme stuttering in more modern titles. The limitations lead us to believe that Intel doesn’t want to compete with its own more expensive 2C/4T unlocked i3 and locked i3-7100 ($120) & 7300 ($150).

Ask GN returns after a hiatus due to nonstop video card and CPU reviews, re-opening coverage with a discussion on temperature impact on components, noise optimization for GPUs, CLC mounting methods, and a bit more.

Oh, and we got more pucks from NZXT – but at least this one’s blue.

For timestamps, continue on. The video is embedded below:

The EVGA GTX 1080 Ti FTW3 is the company’s attempt at a 3-fan cooler, entering EVGA into the three-fan ranks alongside ASUS, Gigabyte, and MSI. The difference with EVGA’s card, though, is that it’s a two-slot design; board partners have gone with a “bigger is better” mentality for the 1080 Ti, and it’s not necessarily advantageous. Sure, there are benefits – taller cards mean taller fans, like on the Gaming X, which results in slower rotation of fans without sacrificing volume of air moved. It follows then that taller fans on taller cards could be profiled to run quieter, without necessarily sacrificing thermal performance of the GPU, VRM, and VRAM components.

But we’re testing today to see how all that plays out in reality. In our EVGA GTX 1080 Ti FTW3 review, we benchmark the card vs. EVGA’s own SC2, MSI’s 1080 Ti Gaming X, Gigabyte’s Xtreme Aorus, and the Founders Edition card. Each of these also has an individual review posted, if you’re looking for break-outs on any one device. See the following links for those (listed in order of publication):

It’s Not About Gaming Performance

Having reviewed this many cards in the past few weeks, it should be apparent to everyone that same-GPU cards aren’t really differentiated by gaming performance. Gaming performance is going to be within a few percentage points of all devices, no matter what, because they’re ultimately governed by the GPU. A manufacturer can throw the world’s best PCB, VRM, and cooler together, and it’s still going to hit a Pascal wall of voltage and power budget. Further, chip quality dictates performance in greater ways than PCB or VRM will. We have duplicates of most of our cards, and they can perform 1-3% apart from one another, depending on which boosts higher out-of-box.

For anyone who missed the news last week, Final Fantasy XIV: Stormblood has a freshly released benchmarking tool included in the download.

In anticipation of the official release of Final Fantasy XIV: Stormblood, Square Enix has revealed a benchmark tool, and a new trailer – itself a recording of the benchmark.

Final Fantasy XIV has never exactly been a demanding title for PC hardware; however, the release of the Stormblood expansion marks the end of PS3 support, which has effectively served as the lowest common denominator while developing the MMORPG across multiple platforms. With the PS3’s hardware limitations no longer a constraint—plus an upgraded North American Data Center—Square Enix has vowed both graphical and functional advancements (think inventory space) over both A Realm Reborn and Heavensward.

We came away from our revisit of the once-king Sandy Bridge 2600K and 2500K CPUs impressed by the staying power of products that came out in Q1 2011, considering Intel’s unimpressive gains since that time.

At the time of Sandy Bridge’s release, AMD’s flagship CPUs were 45nm K10-based Phenom IIs, designed to compete in price/performance with the 45nm Lynnfield (Nehalem i5) quad cores. Later that year, AMD’s underwhelming Bulldozer architecture would launch and inevitably replace the Phenom line. Given that we’ve already looked at Intel’s 1Q11 offerings, we decided to revisit AMD’s Phenom II CPUs in 2017, including the Phenom II X6 1090T (Black Edition) and Phenom II X6 1055T. These benchmarks look at AMD Phenom II performance in gaming and production workloads for the modern era, including comparisons to the equal-aged Sandy Bridge CPUs, modern Ryzen 5 & 7 CPUs, and modern Intel CPUs.

We moderate comments on a ~24~48 hour cycle. There will be some delay after submitting a comment.
