For our 2700/2700X review, we wanted to see how Ryzen 2’s volt-frequency performance compared to Ryzen 1. We took our Ryzen 7 2700X and an R7 1700 and clocked them both to 4GHz, and then found the lowest possible voltage that would allow them to survive stress tests in Blender and Prime95. Full results are included in that review, but the most important point was this: the 1700 needed at least 1.425v to maintain stability, while the 2700X required only 1.162v (value reported by HWiNFO, not what was set in BIOS).
This drew our attention, because we already knew that our 2700X could barely manage 4.2GHz at >1.425v. In other words, a 5% increase in frequency from 4 to 4.2GHz required a 22.6% increase in reported voltage.
Frequency in Ryzen 2 has started to behave like GPU Boost 3.0, where temperature, power consumption, and voltage heavily impact boosting behavior when left unmanaged. Our initial experience with Ryzen 2 led us to believe that a volt-frequency curve would look almost exponential, like the one on the screen now. That was our hypothesis. To be clear, we can push frequency higher with reference clock increases to 102 or 103MHz and can then sustain 4.2GHz at lower voltages, or even 4.25GHz and up, but that’s not our goal. Our goal is to plot a volt-frequency curve with just multiplier and voltage modifications. We typically run out of thermal headroom before we run out of safe voltage headroom, but if voltage increases exponentially, that will quickly become a problem.
We covered Lian Li’s O11 Dynamic at CES earlier this year. It’s related to the older PC-O11 model, but this new version was designed in collaboration with professional overclocker Der8auer, whom we’ve interviewed several times. It’s obvious that he knows how important good cooling is, and his delidding tools make it clear that he wouldn’t carelessly put his name on a low quality product, so we were very interested in getting our hands on one of these cases for review.
Lian Li also has a reputation, and it doesn’t involve making enclosures that are normal looking or affordable by mortals. They took a step away from that reputation with the Alpha 550X and 330, cases that at least approach a competitive price. The O11 Dynamic goes a step further, with the Newegg pre-order price set at an affordable $100, or $130 by the time this is published.
Our Lian Li O11 Dynamic review precedes the inevitable O11 Air review, which is due for a release date in May or June. The O11 Dynamic will begin shipping immediately, and is targeted more for liquid cooling enthusiasts than air-cooled builds -- but you could still buy fans, obviously, and air cool the O11 Dynamic.
Elgato’s 4K60 Pro capture card is an internal PCIe x4 capture card capable of handling resolutions up to 3840x2160 at 60 frames per second, as the name implies. It launched in November with an MSRP of $400, and has remained around that price since.
The Amazon reviews for the 4K60 Pro are almost worthless, because Amazon considers the 4K60 Pro and Elgato’s 1080p-capable HD60 Pro to be varieties of the same product and groups their reviews together. There are only twenty-something reviews of the 4K60 compared to nearly two thousand for the HD60, so that may skew the results slightly. Of the three single-star reviews that are actually for the 4K60, one is from a gentleman who was expecting a seven-inch-long PCIe card to work in a laptop. As of this writing, nobody at all has reviewed it on Newegg, and it’s on sale for $12 off in both locations.
It doesn’t seem like these are flying off the shelves, which probably speaks more to the current demand for 4K 60FPS streaming than the product itself--it’s the cheapest of a very small number of 4K60-capable capture cards, and there’s not any consumer-level competition to speak of. $400 may seem like a lot, but the existing alternatives are much more expensive, like the Magewell Pro Capture HDMI 4K Plus, which (besides having an awful name) costs around $800-$900. The Magewell does have a heatsink and a fan, though, which the 4K60 Pro does not--more on that later.
This Elgato 4K60 Pro review looks at the capture card’s quality and capabilities for both console and PC capture, and also walks through some thermal and temperature measurements taken with thermocouples.
Sea of Thieves, the multiplayer-adventure-survival-pirate simulator from Rare, has finally been released after months of betas and stress tests. Judging by the difficulty they’ve had keeping the servers up after all that preparation, it seems like it’s been pretty popular. This comparison looks at Sea of Thieves Xbox One X vs. PC graphics quality, equalized graphics settings, and framerate/frametime performance on the Xbox.
SoT is also one of the first really big multiplayer titles to be added to the “Xbox Play Anywhere Program.” That means that it’s playable on both Xbox One and Windows 10 with a single purchase (yes, it’s a Windows 10 exclusive DX11 game). Also, Xbox and PC players are free to encounter each other ingame or even party up together, with the only obvious downside being forced to interact with the Windows 10 store and Xbox app. Together, these two aspects make a PC vs Xbox a very interesting comparison, since any player that owns a PC and an Xbox could easily switch.
The Thermaltake View 37 is the latest addition to Thermaltake’s big-transparent-window-themed View series. It’s similar in appearance to the older View 27, but with a much larger acrylic window and less internal shrouding.
The acrylic window is impressive, and it’s about the best it can be without using tempered glass. Manufacturing curved glass panels is difficult and expensive, and using glass would probably bring the price closer to $200 (or above, for the RGB version). As it is, the acrylic is thick and well-tooled so it’s basically indistinguishable from glass, other than a tendency to collect dust and small scratches. Acrylic was the right choice to ship with this case, but if Thermaltake sticks to past patterns they may offer a separate glass panel in the future.
