Gourmet Coffee, Gigabyte's Z370 Aorus Gaming 7

Subject: Motherboards | October 13, 2017 - 02:45 PM |
Tagged: gigabye, Z370, aorus gaming 7, coffee lake, Intel

Gigabyte's Z370 Aorus Gaming 7 is the most feature filled example of this chipset that The Tech Report have yet reviewed and at $250 it costs significantly less than the flagship models of previous generations.  There are three each of PCIe 3.0 x16 slots, PCIe 3.0 x1 slots and M.2 ports as well as six SATA ports; a beautiful array of options which utilize more PCIe lanes than are available on this platform so you will need to do some planning before purchasing your storage devices.  Audio is handled by Realtec's S1220 with help from an ESS Sabre 9018Q2C DAC installed in way which isolates it from interference from other components.  The back panel features HDMI 1.4, DP 1.2 and a USB 3.1 Type C port as well as numerous other earlier generation USB ports and even an old PS/2 for those that need it.  The list of features and high end components present on this board is much longer than this, check out the full review to reveal them all.

How hot is your Coffee?

Subject: Processors | October 10, 2017 - 06:35 PM |
Tagged: Intel, coffee lake, i7 8700k

The Tech Report addresses two questions about Intel's i7-8700K in their latest review, how to keep it running cool and how the multi-core enhancement feature changes that answer.  Multi-core enhancement is a BIOS level overclocking feature which allows all cores on Coffee Lake processors to hit the full boost clock instead of only a single core.  In this example, a single core could hit 4.7 GHz while the other cores are being limited to 4.3GHz, however with multi-core enhancement enabled that limit is removed and all cores can hit 4.7GHz simultaneously.  As with any type of overclock this produces significantly more heat and requires more cooling.

This enhancement means there are two answers to the question about cooling your Coffee.  With the enhancement feature disabled you should be just fine with a CM Hyper 212 Evo or equivalent heatsink, however with MCE enabled even a Corsair H115i shows a 90° C package temperature with core temps between 84-90C.  Keep this in mind when shopping for parts; it is nice to have all cores running at their full Boost Clock but you will need to be able to cool them or else see throttling as the chip sense Tjunction temps in excess of 100C.

"Intel's Core i7-8700K proved an exceptionally well-rounded chip in our testing, but the company's choice of thermal interface material has left many wondering whether the Coffee Lake flagship will prove a challenge to keep cool. We establish a handy baseline for what might make a chip "difficult" to cool and see whether the Core i7-8700K falls on the wrong side of the line."

Extreme Overclockers Fill Coffee Lake With Liquid Nitrogen

Subject: Processors | October 6, 2017 - 11:44 PM |
Tagged: Extreme Overclocking Competition, overclocking, liquid nitrogen, coffee lake, i7 8700k

A new CPU means new overclocking challenges and with it comes a new batch of refreshed Z370 motherboards. At the high end, the current frequency record for the Core i7 8700K is 7,405.1 MHz obtained by Hovan Yang using a MSI Z370 Godlike Gaming motherboard.

image_id_1912600.jpeg

He’s not the only one testing the limits of Intel’s new six core processors though. Asus held an overclocking event a few weeks ago where renowned overclockers Alex@ro, elmor, der8auer, Rsannino, and shamino battled it out. Der8auer got a pre-release crack at the i7 8700K at the event and after de-lidding and replacing the TIM with liberal amounts of Kryonaut thermal paste managed to achieve 6.8 GHz using 1.8 volts and a 68x multiplier (and bumping the cache speed up to 6.3 GHz). With these settings on the monster Maximus X Apex motherboard, he scored 299 in single threaded and 2253 in multithreaded in Cinebench R15. Der8auer compared this benchmark result to Skylake X at 5.5 GHz scoring 237 in the single threaded test. Following the benchmark run, he went for the highest CPU-z validated clockspeed he could hit and managed to push the chip to 7300 MHz (100MHzx73). From there overclocker Alex from Romania was able to overclock his i7 8700K to 6844 MHz and scored 2306 in Cinebench R15.

The overclockers broke 10 new records in the six core CPU category and also managed to break a DDR4 clockspeed record by pushing a single 8GB G.Skill DIMM to 5529.2 MHz at 24-31-31-63-3 timings!

Also of note is that Coffee Lake does not depend of FIVR so overclockers are able to use a full pot of liquid nitrogen (or liquid helium) to cool the processor down to much lower temperatures so that they can crank up the voltage and achieve much higher clockspeeds than Skylake-X which cannot boot if temperatures are too low.

While the ASUS team does not hold the clockspeed record anymore (though they might regain it with some Liquid Helium), der8auer has an interesting video and Asus has a blog post with photos talking about the process, setup, and everything that goes into these extreme overclocking sessions including pre-binning the chips, preparing the IHS and motherboard for the super cold (-185°C to -190°C) temperatures, and keeping the processors and motherboards running. For example, and Josh will be interested in this, part of the process of preparing the motherboard involves slathering it in Vaseline!

If you are interested in this extreme overclocking stuff it gives a bit of insight into all the fun to be had!

Leaked Update Shows Intel Launching New 300-Series Chipsets In 2018

Subject: Motherboards | October 5, 2017 - 05:42 PM |
Tagged: Z390, Z370, Q370, Q360, leaks, Intel, H370, H310, coffee lake, chipsets, B360

Thanks to a leaked Intel Launch Update document we now know that Intel is planning to launch a slew of new 300-series chipsets early next year. Reportedly vetted by Gamer's Nexus, the leaked roadmap mentions H310, H370, and B360 on the consumer side, Q370 and Q360 for the business market. There is also a tease of a Z390 chipset that is set to replace Z370 as the high-end motherboard platform of choice.

Intel B360 H310 H370 chipsets in Q1 2018.jpg

As if things were not already confusing enough in the _370 chipset space (with Intel's Z370 and AMD's X370), Intel plans to add a H370 chipset to the mix which should be a bit cheaper and have less overclocking, PCI-E slots, and M.2 ports. Intel has also had to tweak the name for its B series chipset to B360 as well so as to not confuse itself with AMD's B350 chipset offering. Finally, there will be a H310 chipset for budget options. These three consumer chipsets are slated for launch in Q1 2018.

For its business customers, Intel plans to launch Q370 and Q360 chipsets in Q2 2018.

Finally, Intel is rumored to launch a Z390 chipset sometime in the second half of next year (2H 2018). According to Gamer's Nexus, industry sources have indicated that Z370 is more of a "stop gap" solution that Intel used to quickly roll out its Coffee Lake processors. Z370 is intended to only support Coffee Lake and while engineering boards were able to support Kaby Lake-R and Coffee Lake CPUs, this functionality has been disabled in firmware. Z370 based motherboards reportedly have tweaked PCB trace optimizations and power delivery needed to support the new processors. Z390 meanwhile will be the successor to Z370 in 2018 and will offically support the entire range of consumer level Coffee Lake processors as well as rumored 8 core (16 thread) processors of undetermined architecture (maybe 14nm++ Coffee Lake but would be a rather big but not unheard of die at ~176mm^2 so rumors also speculate that these 8 core parts could be based on 10nm Ice Lake instead).

Beyond the existence of these chipsets, the ILU did not go into details on the features they would offer or things like price points for motherboards based on them, naturally. As usual you should take these types of leaks with a teaspoon of salt, but it is interesting that Intel may be stepping up their game in rolling out new products faster and moving more cores to the mainstream chips--finally!

Fremont, CA (October 5, 2017) — The new Intel® 8th Generation Core™ processors are the best desktop CPUs for gaming on the market. With up to six cores and 12 threads, these Coffee Lake chips also have huge potential for enthusiasts and power users who do more with their PCs. Their exceptional performance, unmatched versatility, and considerable overclocking potential are a natural fit for Republic of Gamers (ROG), so we’ve developed a diverse collection of Z370 gaming motherboards for a range of priorities and budgets.

Our latest lineup reinforces ROG’s role as both a breeding ground for innovative features and a proving ground where we test the absolute limits of performance. It includes standouts like the Maximus X Apex, a hardcore gaming and overclocking board designed to break performance records; the Maximus X Hero, which blends leading performance with premium extras; the Maximus X Code that redefines the performance essentials for gamers and enthusiasts; and the Maximus X Formula, which is brimming with cutting-edge features fit for showcase PCs.

While the Maximus series covers the higher end of the spectrum, the Strix family opens the Republic of Gamers to a wider audience. It provides everything you need in a gaming motherboard but excludes some of our more indulgent extras to hit affordable price points. Full-sized ATX options include closely matched contenders for the sweet spot, the Strix Z370-E and Z370-F Gaming, and an unexpected retro revival, the Strix Z370-H Gaming. Smaller form factors are served by the mATX Strix Z370-G Gaming and Mini-ITX Strix Z370-I Gaming.

Defined by gamers, powered by innovation, discover the all-new ROG Z370 lineup at ASUS ROG.

Setting the Benchmark for Records
Lots of motherboard makers claim the best performance, but we’ve got the results to prove it. Much of the credit goes to the Apex, an overclocking savant purpose-built for taking new CPUs to the ragged edge at sub-zero temperatures. Apex boards were introduced earlier this year with the Maximus IX series, and they’ve already claimed multiple world records and top scores with Intel’s Z270 and X299 platforms. Now, our internal overclocking team has continued that streak with the new Maximus X Apex, setting the highest 8th Generation Core i7-8700K frequency record by reaching 7.3GHz on all 6-cores and 12-threads. In addition, the highest DDR4 memory frequency record with a top speed of 5529.2MHz. For the complete story on Z370 overclocking please visit our article at ASUS ROG.

[H]ard|OCP had an opportunity to try a different Coffee Lake CPU than Ryan, who provided our initial results on the i7-8700K and Core i5-8400.  In this review, they took a Core i5-8600K and immediately overclocked the chip to 5GHz so they could directly compare Coffee Lake to a Kaby Lake i5-7600K clock for clock, if not for core.  The tests show both CPUs at 5GHz locked clocks, 3600MHz RAM clocks with the exact same timings of 18-19-19-39@2T; they do not show a major improvement in performance between the two chips although it is there.  What it does illustrate is that the performance increased you see on Coffee Lake are from higher clock speeds, which are a good thing.  There will be many who feel the lack of IPC improvement speaks poorly of the new chipset and incompatible socket and they do have a point.   There is fun for AMD fans in this review as well, the Ryzen 7 takes top spot even when running at a mere 4GHz, so start with this one and then take a gander through the rest.

"If you were waiting for huge IPC gains out of the new Coffee Lake CPU from Intel, you might be waiting for a very long time. We take the Intel Coffee Lake Core i5-8600K CPU and match it up GHz to GHz with the Intel Core i5-7600K Kaby Lake processor. And we throw in a Ryzen 7 at 4GHz just for fun."

Specifications and Summary

As seems to be the trend for processor reviews as of late, today marks the second in a two-part reveal of Intel’s Coffee Lake consumer platform. We essentially know all there is to know about the new mainstream and DIY PC processors from Intel, including specifications, platform requirements, and even pricing; all that is missing is performance. That is the story we get to tell you today in our review of the Core i7-8700K and Core i5-8400.

Coffee Lake is the second spoke of Intel's “8th generation” wheel that began with the Kaby Lake-R release featuring quad-core 15-watt notebook processors for the thin and light market. Though today’s release of the Coffee Lake-S series (the S is the designation for consumer desktop) doesn’t share the same code name, it does share the same microarchitecture, same ring bus design (no mesh here), and same underlying technology. They are both built on the Intel 14nm process technology.

IMG_4888.JPG

And much like Kaby Lake-R in the notebook front, Coffee Lake is here to raise the core count and performance profile of the mainstream Intel CPU playbook. When AMD first launched the Ryzen 7 series of processors that brought 8-cores and 16-threads of compute, it fundamentally shook the mainstream consumer markets. Intel was still on top in terms of IPC and core clock speeds, giving it the edge in single and lightly threaded workloads, but AMD had released a part with double the core and thread count and was able to dominate in most multi-threaded workloads compared to similar Intel offerings.

Much like Skylake-X before it, Coffee Lake had been on Intel’s roadmap from the beginning, but new pressure from a revived AMD meant bringing that technology to the forefront sooner rather than later in an effort stem any potential shifts in market share and maybe more importantly, mind share among investors, gamers, and builders. Coffee Lake, and the Core i7, Core i5, and Core i3 processors that will be a part of this 8000-series release, increase the core count across the board, and generally raise clock speeds too. Intel is hoping that by bumping its top mainstream CPU to 6-cores, and coupling that with better IPC and higher clocks, it can alleviate the advantages that AMD has with Ryzen.

But does it?

That’s what we are here to find out today. If you need a refresher on the build up to this release, we have the specifications and slight changes in the platform and design summarized for you below. Otherwise, feel free to jump on over to the benchmarks!
