Overclocking engineer "Der8auer" has come out with his newest product: The Skylake-X Direct Die Frame cooling bracket. The bracket is intended to replace the ILM (independent loading mechanism) on the motherboard, used to act as a shim between a delidded CPU and a cooler. The goal is to not only delid the CPU and replace the compound, but also completely eliminate the heatspreader. Traditionally, the IHS would be kept post-delid, just with better compound and with removal of the silicone adhesive. In this application, you would delid the CPU, refresh the compound, remove the adhesive, and leave the IHS off, then mount it in the Skylake-X direct die bracket.

Some of our recent delid-focused content, "What We've Learned Delidding Intel CPUs," has highlighted that a light silicone adhesive seal vs. no seal vs. heavy seal can have significant impact on cooling. Heavy seals, for instance, can easily result in worse performance than stock -- even with liquid metal. We recommend not resealing the IHS at all and just allowing the cooler to retain the IHS, but a seal is sometimes needed. Shipping is a good example of this.

As we pack before CES, this is just a quick video update in a non-standard format. We decided to put together a loose video that details the practical learnings of delidding -- things we've picked up over the past few months of taking the IHS off processors. During this time, we've learned a few tricks pertaining to resealing, preventing electrical shorts and damage, and applying liquid metal. These are all things that we could have used when learning about delidding, and so we decided to compile it into one content piece. The format is less formal and in our "tear-down" setup, just with a different tone to the content.

There’s been a lot of talk of an “Intel bug” lately, to which we paid close attention upon the explosion of our Twitter, email, and YouTube accounts. The “bug” that has been discussed most commonly refers to a new attack vector that can break the bounding boxes of virtual environments, including virtual machines and virtual memory, that has been named “Meltdown.” This attack is known primarily to affect Intel at this time, with indeterminate effect on AMD and ARM. Another attack, “Spectre,” attacks through side channels in speculative execution and branch prediction, and is capable of fetching sensitive user information that is stored in physical memory. Both attacks are severe, and between the two of them, nearly every CPU on the market is affected in at least some capacity. The severity of the impact remains to be seen, and will be largely unveiled upon embargo lift, January 9th, at which time the companies will all be discussing solutions and shortcomings.

For this content piece, we’re focusing on coverage from a strict journalism and reporting perspective, as security and low-level processor exploits are far outside of our area of expertise. That said, a lot of you wanted to know our opinions or thoughts on the matter, so we decided to compile a report of research from around the web. Note that we are not providing opinion here, just facts, as we are not knowledgeable enough in the subject matter to hold strong opinions (well, outside of “this is bad”).

Just a quick update for everyone: We've got a major feature -- an end-of-year special that includes a short film (something we've never done before) -- going up tomorrow at around 9AM EST. That'll be sort of an end-of-year recap of a few key components, primarily those that disappointed us.

In the meantime, while we were playing one-day roles of directors and cinematographers, we've set to work on delidding another 7980XE. This will be our third delid of the 18C CPU, with another ~4~5 delids of lower-end CPUs from the past few months. Our previous delid was for Kyle of "Bitwit," which later led to our Intel X299 VRM thermal investigation of the ASUS Rampage VI Extreme motherboard's VRM temperatures. It was an excellent opportunity for us to explore potential sideshoot content pieces in more depth, and gave us multiple samples to build a larger sample size.

We're now up to 3x 18C CPUs delidded, and are collecting data on the latest for Ed from Tech Source. The delid just completed, and we're now in the resealing stage.

This episode of Ask GN, shipping on Christmas day, answers a few pertinent questions from the last few weeks: We'll talk about whether we made ROI on the Titan V, whether it makes more sense to buy Ryzen now or wait for Ryzen+/Ryzen2, and then dive into the "minor" topics for the segment. Smaller topics include discussion on choosing games for benchmarking -- primarily, why we don't like ROTTR -- and our thoughts on warranty/support reviews, with some reinforced information on vertical GPU mounting. The conclusion focuses on an ancient video card and some GN modmat information.

Ask GN: Buy or Wait for Volta?

Saturday, 09 December 2017

This episode of Ask GN headlines with answering the most common question we’ve seen in the past 24 hours: Should I buy now or wait for Volta? That’ll start us off for this episode, followed by clarification of VRM quality, a history lesson on AM4 motherboards at launch and HIS existence, and silicon death from overclocking. This episode runs about 25 minutes, with each question timestamped within the video. We also have the timestamps and questions marked below, if you’d like to see when a particular topic of interest appears.

The Volta topic, we think, is among the most interesting and common for questions right now. This seems to come around for every new architecture, and our answers are generally the same. Find out more below!

Cyber Monday is over, but “Black Friday” is now “Black November.” December is also Black November. Next year is Black 2018. Welcome to the future, where the deals are infinite and yet 8GB of memory still costs nearly $100.

Regardless, we’ve got a few that are worthwhile: There’s an i7-7700K for $290, an EVGA SuperNova 650 for $65, and an AMD bundle kit below.

Intel’s 8600K CPU changes the story significantly for the company’s i5 lineup. When AMD’s R5 CPUs launched, we noted that the i5-7600K 4C/4T CPU had a “fading grasp,” highlighting that the R5 1600(X) achieved close enough gaming performance while offering greater versatility. The gap between an R7 and i7 remained much more significant – enough that we could, and do, still recommend an i7 for some workloads – but the R5 and i5 distance grew closer, and so the R5s became easy to recommend. Now, with the i5-8600K, Intel moves its mid-range lineup to 6C/6T designs, maintains high clocks (higher, even), and potentially makes up for losses on the 4C units.

We just bought Intel’s i5-8600K CPU for $300, following high demand for a review, and ran it through the benchmark ringer. We’ve previously reviewed other Intel 8th Gen units, including the i7-8700K (review here), the i5-8400 (review here), and the i3-8350K (review here). This review looks at the Intel i5-8600K benchmark performance, including overclocking (to 5GHz), Blender, gaming, thermals, and power consumption.

The recent trend in memory prices have put a major hold on our PC build guides. For years – most of its 10-year existence – GN has published nearly monthly gaming & workstation PC build guides. We haven’t published one for several months now, and that’s because of the simultaneous collision of memory and video card prices. The two all-time high price jumps on GPUs (miner+gamer joint demand) and RAM (supply shortage & process switch) made PC building nearly impossible to afford. There’s been some alleviation of that lately, but not in memory prices directly. The onslaught of Cyber Monday and Black Friday sales have brought down other components enough to more or less neutralize the insane RAM pricing; now, for instance, the 1950X is $200 off MSRP, which instantly counters the RAM pricing being 2x what it should be. For this reason, we decided to revisit our PC build guides with a Threadripper 1950X workstation, built for 3D rendering (Blender), H264 video encoding with Handbrake, and some other batch processing work and Adobe Premiere work.

A Note About PC Builds

PC builds always get comments from people who want to express their infinite wisdom and intelligence in comments fields, likely because, of all the things we publish, PC building is the item with which folks have the most experience. A note, here: We’re building based on two primary criteria, which include:

  • - We have used and tested the parts, and trust them for this build.
  • - We are using this build internally as a temporary encode/render system, which means that it’s mostly to suit our needs; if you can do better, great, but we’re going for a workstation that can get our jobs done, then be unbuilt.

There are places you can cut costs on this build. We’ll include alternative parts listings for those instances.

With our Best AM4 Overclocking Motherboards content up, we figured it was time to publish something in the same vein for Intel. Intel presently has two mainstream platforms: the 200-series and 300-series, with the former hosting Kaby Lake CPUs (like the i7-7700K, presently on sale) and the Skylake-X/KBL-X series (X299), while the latter hosts the new Coffee Lake series (i7-8700K, i5-8400). Oddly, Intel decided against launching Coffee Lake with lower-tier B-series motherboards, so we’re left with only Z370 to fill both the mainstream and enthusiast segments of Coffee Lake.

We rummaged through the Internet’s Black Friday sales to find the best Z370 and Z270 Intel motherboards, including boards we think fitting for the 8700K, 8500, 8300, and 7700K. If you missed our previous content, we have a GN Pick Black Friday Sales guide (that lists some CPUs), a DDR4 memory sales guide, and a Best CPUs of 2017 listing. For those unsure of which CPU to buy, we have reviews of the i7-8700K here, the i5-8400 here, and the i3-8350K over here. If you’re interested in Ryzen stuff, check out our motherboard round-up or Best CPUs guide, both linked above.
