Hardware Guides

Revisiting an article from GN days of yore, GamersNexus endeavored to explain the differences between Western Digital’s WD Blue, Black, Red, and Purple hard drives. In this content, we also explain the specs and differences between WD Green vs. Blue & Black SSDs. In recent years, Western Digital’s product stack as changed considerably, as has the HDD market in general. We’ve found it fitting to resurrect this WD Blue, Black, Green, Red, and Purple drive naming scheme explanation. We’ll talk about the best drives for each purpose (e.g. WD Blue vs. Black for gaming), then dig into the new SSDs.

Unchanged over the years is Western Digital’s affinity for deferring to colors as to identify products, where other HDD vendors prefer fantastic creature names (BarraCuda, IronWolf, SkyHawk, etc.). As stated above, Western Digital has seriously changed its lineup. The WD Green drives have been painted blue, as they’ve been folded into the WD Blue umbrella. Furthermore, the WD Blue brand has seen the addition of an SSHD offering and SSDs in both 2.5” and M.2 form factors. This in no small part thanks to Western Digital’s acquisition of SanDisk—another notable development since our last article. With that, the WD Blue brand has expanded to become Western Digital’s most comprehensive mainstream product line-up.

Other changes to the Western Digital rainbow include the expanding of WD Black, and confusingly enough, WD Green brands. Starting with the latter, Western Digital rebranded all WD Green HDDs as WD Blue, selling WD Blues under two different RPMs, but recently reentered the SSD market with both. However, the WD Green SSDs are currently unavailable, perhaps due to the global NAND shortage. Likewise, the WD Black series has spilled over into the realm of NVMe/PCIe based storage and WD Black HDDs have expanded capacities up to 6TB; that’s quite a change from the 4TB flagship model we covered back in 2014. Lastly, there is WD Purple, of which we will retroactively cover here.

We made Gigabyte aware of an unnecessarily high auto vCore table back in December, prior to the launch and NDA lift of Kaby Lake processors. By the time of review, that still hadn’t been resolved, and we noted in our Gigabyte Aorus Z270X Gaming 7 review that we’d revisit thermals if the company issued an update. Today, we’re doing just that. Gigabyte passed relevant information along to engineering teams and worked quickly to resolve the high auto vCore (and thus high CPU temperatures) on the Gaming 7 motherboard.

We’ve been impressed with Gigabyte’s responses overall. The representatives have been exceptionally helpful in troubleshooting the issue, and were open ears when we presented our initial concerns. The quick turn-around time on a BIOS update and subsequent auto vCore reduction shows that they’re listening, which is more than we can say for a lot of companies in this business. In an industry where it’s easier to jam fingers in ears and ignore a problem, Gigabyte’s fixed this one.

Here’s the original board review with the temperature criticisms, something we also talked about in our 7700K review.

Every now and then, a new marketing gimmick comes along that feels a little untested. MSI’s latest M.2 heat shield always struck us as high on the list of potentially untested marketing claims. The idea that the “shield” can perform two opposing functions – shielding an SSD from external heat while somehow simultaneously sinking heat from within – seems like it’s written by marketing, not by engineering.

From a “shielding” standpoint, it might make sense; if you’ve got a second video card socketed above the M.2 SSD and dumping heat onto it, a shield could in fact help keep heat from touching SMT components. This would include Flash modules and controllers that may otherwise be in a direct heat path. From a heat sinking standpoint, a separate M.2 heatsink would also make sense. M.2 SSDs are notoriously hot resultant of their lower surface area and general lack of housing (ignoring the M8Pe and similar devices), and running high temperatures in a case with unfavorable ambient will result in throttled performance. MSI thought that adding this “shield” to the M.2 slot would solve the issue of hot M.2 SSDs, but it’s got a few problems that don’t even require testing to understand: (1) the “shield” (or sink, whatever) doesn’t enshroud the underside of the M.2 device, where SMDs will likely be present; (2) the cover is designed more like a shield than a sink (despite MSI’s marketing language – see below), and that means we’ve got limited surface area with zero dissipation potential.

In the latest feature from overclocker Buildzoid, we follow-up on our full review of the Gigabyte Z270X Gaming 7 motherboard with a VRM analysis of the motherboard. The Gigabyte Gaming 7 of the Z270X family, ready for Kaby Lake, is one of the pricier boards at $240 and attempts to justify its cost in two ways: Overclocking features and RGB LEDs (naturally).

To use any processing product for six years is a remarkable feat. GPUs struggle to hang on for that amount of time. You’d be reducing graphics settings heavily after the second or third year, and likely considering an upgrade around the same time. Intel’s CPUs are different – they don’t change much, and we almost always recommend skipping at least one generation between upgrades (for the gaming audience, anyway). The 7700K increased temperatures substantially and didn’t increase performance in-step, making it a pointless upgrade for any owners of the i7-6700K or i7-4690K.

We did remark in the review that owners of the 2500K and 2600K may want to consider finally moving up to Kaby Lake, but if we think about that for a second, it almost seems ridiculous: Sandy Bridge is an architecture from 2011. The i5-2500K came out in 1Q11, making it about six years old as of 2017. That is some serious staying power. Intel shows gains less than 10% generationally with almost absolute certainty. We see double-digits jumps in Blender performance and some production workloads, but that is still not an occurrence with every architecture launch. With gaming, based on the 6700K to 7700K jump, you’re lucky to get more than 1.5-3% extra performance. That’s counting frametime performance, too.

AMD’s architectural jumps should be a different story, in theory, but that’s mostly because Zen is planted 5 years after the launch of the FX-8350. AMD did have subsequent clock-rate increases and various rebadges or power efficiency improvements (FX-8370, FX 8320E), but those weren’t really that exciting for existing owners of 8000-series CPUs. In that regard, it’s the same story as Intel. AMD’s Ryzen will certainly post large gains over AMD’s last architecture given the sizeable temporal gap between launches, but we still have no idea how the next iteration will scale. It could well be just as slow as Intel’s scaling, depending on what architectural and process walls AMD may run into.

That’s not really the point of this article, though; today, we’re looking at whether it’s finally time to upgrade the i5-2500K CPU. Owners of the i5-2500K did well to buy one, it turns out, because the only major desire to upgrade would likely stem from a want of more I/O options (like M.2, NVMe, and USB3.1 Gen2 support). Hard performance is finally becoming a reason to upgrade, as we’ll show, but we’d still rank changes to HSIO as the biggest driver in upgrade demand. In the time since 2011, PCIe Gen3 has proliferated across all relevant platforms, USB3.x ports have increased to double-digits on some boards, M.2 and NVMe have entered the field of SSDs, and SATA III is on its way out as a storage interface.

After receiving a number of emails asking how to flash motherboard BIOS, we decided to revive an old series of ours and revisit each motherboard vendor’s flashing process as quickly as possible. This is particularly useful for users residing on the Z170 platform who may want to flash to support Kaby Lake CPUs. The process is the same for all modern MSI motherboards, and will work across all SKUs (with some caveats and disclaimers).

This tutorial shows how to flash firmware and update BIOS for MSI motherboards, including the new Z270 Pro Carbon / Tomahawk boards and ‘old’ Gaming M7 Z170 motherboards. For this guide, we’re primarily showing the MSI Z270 Gaming Pro Carbon, but we do briefly have some shots of the Tomahawk Z270 board. This guide applies retroactively to Z170 motherboards, and even most Z97 motherboards.

Best Gaming PC Cases of 2017 | CES Round-Up

By Published January 13, 2017 at 4:00 pm

This year’s case manufacturers will primarily be focused on shifting to USB Type-C – you heard it here first – as the upcoming trend for case design. Last year, it was a craze to adopt tempered glass and RGB LEDs, and that’s plainly not stopped with this year’s CES. That trend will carry through the half of 2017, and will likely give way to Type-C-heavy cases at Computex in May-June.

For today, we’re looking at the best PC cases of 2017 thus far, as shown at the annual Consumer Electronics Show (CES). Our case round-ups are run every year and help to determine upcoming trends in the PC cases arena. This year’s collection of the top computer cases (from $60 to $2000) covers the major budget ranges for PC building.

AMD’s Ryzen platform is on its march to the launch window – likely February of 2017 – and will be pushing non-stop information until its time of delivery. For today, we’re looking at the CPU and chipset architectures in greater depth, following-up on yesterday’s motherboard reveal.

First, let’s clear-up nomenclature confusion: “Zen” is still the AMD next generation CPU architecture name. “Ryzen” is the family of CPUs, comparable to Intel’s “Core” family in some loose ways. Each Ryzen CPU will exist on the Zen architecture, and each Ryzen CPU will have its own individual alphanumeric identifier (just like always).

Optane is Intel’s latest memory technology. The long-term goal for Optane is for it to be used as a supplemental system memory, caching storage, and primary storage inside PCs. Intel claims that Optane is faster than Flash NAND, only slightly slower than DRAM, has higher endurance than NAND, and, due to its density, will be about half the cost of DRAM. The catch with all of these claims is that Intel has yet to release any concrete data on the product.

What we do know is that Lenovo announced that they will be using a 16GB M.2 Optane drive for caching in a couple of their new laptops during Q1 2017. Intel also announced that another 32GB caching drive should be available later in the year, something we’ve been looking into following CES 2017. This article will look into what Intel Optane actually is, how we think it works, and whether it's actually a viable device for the enthusiast market.

AMD’s Vega GPU architecture has received cursory details pertaining to high-bandwidth caching, an iterative step to CUs (NCUs), and a unified-but-not-unified memory configuration.

Going into this, note that we’re still not 100% briefed on Vega. We’ve worked with AMD to try and better understand the architecture, but the details aren’t fully organized for press just yet; we’re also not privy to product details at this time, which would be those more closely associated with shader counts, memory capacity, and individual SKUs. Instead, we have some high-level architecture discussion. It’s enough for a start.

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