Computex is coming up. We'll be at the show next week, which means most of our time will likely be spent covering new X570 motherboards for AMD and AMD's announcements, with NVIDIA's presence sparse at the show and Intel's focused on mobile. Beyond the motherboards and CPUs, we already have numerous cooler and case manufacturers lined-up for meetings, alongside some GPU board partners. In the meantime, this past week has set the stage for Computex with a focus on security vulnerabilities, tariffs, and X570 chipset sightings.

The show notes are below the embedded video.

Other than the most exciting news -- that GN has restocked its Blueprint shirt -- there are other items for the past week that are also interesting, like AMD's Ryzen 3200G allegedly getting a delid and overclock, or Microsoft changing its tune on CPU shortages affecting Windows 10 adoption. Additional news includes Laptop Mag's research into notebook manufacturer support teams, ShadowHammer affecting 6 more companies (in addition to ASUS previously), and Samsung investment news.

As always, show notes follow the video embed.

In case you find it boring to watch an IHS get sanded for ten minutes, we’ve written-up this recap of our newest video. The content features a lapped AMD Ryzen APU IHS for the R3 2200G, which we previously delidded and later topped with a custom copper Rockit Cool IHS. For this next thermal benchmark, we sanded down the AMD Ryzen APU IHS with 600 grit, 1200 grit, 1500 grit, 2000 grit, and then 3000 grit (wet) to smooth-out the IHS surface. After this, we used a polishing rag and compound to further buff the IHS (not shown in the video, because it is exceptionally boring to watch), then we cleaned it and ran the new heatspreader through our standardized thermal benchmark.

We’ve previously tested custom copper integrated heat spreaders (IHS) for Intel, primarily the unit sold by Rockit Cool for LGA115X CPUs. Our findings of the custom copper IHS (sold here) for the i7-8700K were that, generally, it was a fun, worthwhile project at $20, but that the thermal improvement was not game-changing. It was still impressive, though, as we monitored between 4-5 degrees Celsius improvement from the IHS replacement on the 8700K, partly benefiting as a result of the increased surface area over the stock Intel heat spreader. That’s a lot of uplift for something that isn’t a CPU cooler, and if you’re up against hard requirements for noise in your system, it could allow for just enough headroom to slow-down the case fans a bit more.

Ryzen is different, as its heatspreader is one large block, as opposed to a machined block with cut-outs and dips and generally smaller surface area. Rockit Cool improved on Intel IHS performance by increasing surface area, but had little to improve on with AMD’s. Both Intel and AMD use copper IHS units, but all of them are nickel-plated. This shouldn’t impact performance significantly and helps with cleaning.

Today, we’re benchmarking a custom copper IHS for AMD Ryzen CPUs and APUs, using the Rockit Cool copper IHS on an AMD R3 2200G that we previously delidded and benchmarked.

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.

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.

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.

The CPUs discussed today include (Amazon pre-order links below, although we never recommend pre-ordering PC hardware):

Ask GN 75 is an excellent episode. We had great questions for this one, including discussion on X370 vs. X470 benchmarking for Ryzen 2000 series CPUs (e.g. R7 2700X, R5 2600X), which we’ll get in to more detail with in the near future. As noted in the episode, we’re technically not under embargo for the Ryzen 2 CPUs, but we’re planning to hold our review until embargo lift out of respect for AMD’s decision to stop giving special treatment to some media, for this round. That said, we still talk a bit about X370 vs. X470 benchmarking in the Ask GN episode.

The other excellent topic pertained to receiving review samples and balancing hardware criticism – basically behind-the-scenes politics. Find the episode below:

This hardware news update looks into our original CTS Labs story, adding to the research by attempting to communicate with CTS Labs via their PR firm, Bevel PR. We also talk about leaked specifications for the R5 2600X, accidentally posted early to Amazon, and some other leaks on ASUS ROG X470 motherboards.

Minor news items include the loss of power at a Samsung plant, killing 60,000 wafers in the process, and nVidia’s real-time ray-tracing (RTX) demo from GDC.

Show notes below the video.

The past week of hardware news has been peculiarly busy for this time of year, with a deluge of news posting toward the latter half of last week. For major stories, [H]ardOCP’s coverage of nVidia’s GPP agreements has undoubtedly garnered among the most attention in the news cycle, with additional stories of interest covering hacks to get Coffee Lake CPUs functional in Z170 and Z270 motherboards.

We’ve got a couple of minor news items – new liquid coolers, a mini-review of a chair – and a couple of game industry items, like Valve’s return to game development.
