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.
Some controversy bubbled-up recently when reddit, as it does, found its newest offense at which it could express collective rage. That offense was AMD’s CPU warranty, which had previously indicated that any cooler aside from included stock coolers would violate the warranty – not that they’d be able to prove it, if we’re being honest.
We reached-out to AMD for comment when this story went public, and received a response today that AMD had updated its warranty terms for clarity. The original language was meant to prevent warranty replacements for scenarios where the CPU had been damaged by an out-of-spec cooler (think: something like an LN2 pot, or the jury-rigging we do at GN). It was not meant to block warranty replacements for issues unrelated to coolers.
There’s a new trend in the industry: Heatsinks. Hopefully, anyway.
Gigabyte has listened to our never-ending complaints about VRM heatsinks and VRM thermals, and outfitted their X470 Gaming 7 motherboard with a full, proper fin stack and heatpipe. We’re happy to see it, and we hope that this trend continues, but it’s also not entirely necessary on this board. That doesn’t make us less excited to see an actual heatsink on a motherboard; however, we believe it does potentially point toward a future in higher core-count Ryzen CPUs. This is something that Buildzoid speculated in our recent Gaming 7 X470 VRM & PCB analysis. The amount of “overkill” power delivery capabilities on high-end X470 boards would suggest plans to support higher power consumption components from AMD.
Take the Gigabyte Gaming 7: It’s a 10+2-phase VRM, with the VCore VRM using IR3553s for 40A power stages. That alone is enough to run passive, but a heatsink drags temperature so far below requirements of operating spec that there’s room to spare. Cooler is always better in this instance (insofar as ambient cooling, anyway), so we can’t complain, but we can speculate about why it’s been done this way. ASUS’ Crosshair VII Hero has the same VRM, but with 60A power stages. That board, like Gigabyte’s, could run with no heatsink and be fine.
We tested with thermocouples placed on one top-side MOSFET, located adjacent to the SOC VRM MOSFETs (1.2V SOC), and one left-side MOSFET that’s centrally positioned. Our testing included stock and overclocked testing (4.2GHz/1.41VCore at Extreme LLC), then further tested with the heatsink removed entirely. By design, this test had no active airflow over the VRM components. Ambient was controlled during the test and was logged every second.
The AMD R5 2600 and 2600X are, we think, among the more interesting processors that AMD launched for its second generation. The R5 1600 and 1600X received awards from us for 2017, mostly laying claim to “Best All-Around” processor. The 1600 series of R5 CPUs maintained 6 cores, most the gaming performance of the R7 series, and could still capably stream or perform Blender-style production rendering tasks. At the $200-$230 price range, we claimed that it functionally killed the quad-core i5 CPU, later complicated by Intel’s six-core i5 release.
The R5 2600 and 2600X have the same product stack positioning as the 1000-series predecessors, just with higher clock speeds. For specs, the R5 2600X operates at 3.6GHz base and 4.2GHz boost, with the 2600 at 3.4/3.9GHz, and the R5 1600X/1600 operating at a maximum boost of 4.0 and 3.6GHz, respectively.
Reviewing the AMD R7 2700X was done outside of normal review provisions, as AMD didn’t sample us. We’ve had the parts for a month now, and that has meant following development, EFI updates, and more as they’ve been pushed. We have multiple chips of every variety, and have been able to cross-validate as the pre-launch cycle has iterated. Because of the density of data, we’re splitting our content into multiple videos and articles.
Today’s focus will be the AMD R7 2700X and R7 2700 reviews, especially for live streaming performance versus the i7-8700K, gaming performance, and production (Blender) performance. Most importantly, however, we dedicate time to talk about the significant improvements that AMD has made in the volt-frequency department. At a given frequency, e.g. 4.0GHz, Ryzen 2000 operates at a heavily reduced voltage versus Ryzen 1. We’ll dig into this further in this review, but check back later for our R5 2600X and 2600 reviews (combined in one piece), including 2600X vs. 8600K streaming benchmarks. We’re also looking at VRM thermals, motherboard PCBs and their VRM quality, memory overclocking and scalability (in this content), and more.
There is a lot of confusion about AMD’s branding – Zen 2 vs. Ryzen 2 vs. Zen+. We’re calling these CPUs “Ryzen 2,” because they’re literally called “Ryzen 2X00” CPUs. This is not the same as the Zen 2 architecture, which is not out yet.
Note: For overclocking, we only OC one CPU of each core count – so just the R7 2700X or R7 2700, but beyond validation of maximum frequency, there’s no need to OC both and run each through 20 hours of testing.
AMD’s impending Ryzen 2 CPUs – not to be confused with Zen 2, the architecture – will launch on April 19, 9AM EST, and are preempted by yet another “unboxing embargo.” We’re not technically covered under these embargoes, as we’ve sourced parts externally and are operating independently for this launch. That said, as we’ve stated in a few places, we have decided to respect the embargo (although are under no obligation to do so) out of respect for our peers. This is also being done out of trust that AMD has rectified its preferential media treatment exhibited for Threadripper, as we were told the company would do.
Still, we wanted to share some preconditions we’re considering for test cases in our Ryzen 2 CPU reviews. Some of that will be covered here today, with most of the data being held for the April 19 embargo lift. We have been testing and iterating on tests for a few weeks now, updating EFI as new versions push and collecting historical data along the way.
The core specs – those regurgitated all over the internet, undoubtedly – will follow below.

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