Hot on the heels of the HP leak that showed the first AMD Raven Ridge based notebook that may be hitting store shelves later this year, another leak of potential Raven Ridge APU performance is cycling through. The AMD Ryzen 7 2700U with integrated Vega-based graphics architecture, and also rumored to have a ~35-watt TDP, is showing 3DMark11 graphics scores near that of the discrete NVIDIA GeForce MX150.
With a graphics score of 4072, the integrated graphics on the upcoming AMD APU is slightly behind the score of 4570 from the MX150, a difference of 11.5%. Interestingly, the Physics score on the Raven Ridge APU of 6419 is solid as well, and puts an interesting light on the 8th gen KBL-R processors. As you can see in the graph below, from two systems we already have in-house with quad-core parts, CPU performance is going to vary dramatically from one machine to the next depending on the thermal headroom of the physical implementation.
The HP Spectre x360 with the Core i7-8550U and the MX150 GPU is able to generate a Physics score of 8278, well above the leaked result of the Raven Ridge APU. However, when we ran the 3DMark11 on the ASUS Zenbook 3 UX490UA with the same Core i7-8550U, the Physics score was 6627, a 19% drop! Clearly there are configurability shifts that will adjust the performance of the 8th gen Intel parts. We are diving more into this effect in a couple of upcoming reviews.
Though the true power consumption of these Ryzen 7 2700U systems is still up in the air, AMD has claimed for some time that it would have the ability to compete with Intel for the first time in several generations. If these solutions turn out to be in the 35-watt range, which would be at or lower than the typical 15-watt Intel CPU and 25-watt NVIDIA discrete GPU combined, AMD may have a winning combination for mobile performance users to entertain.

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."

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.
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!

[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."

Tagged: amd, ryzen, price cuts
AMD is slashing prices on their Ryzen line of CPUs, and not just in the UK. A Ryzen 7 1800X in the US will cost you only $400 if you skip out on the Wraith cooler, or $500 if you are in Canada. If that is a little too rich a 1700X is $295 or $415 in Canada, though the 1700 with Wraith cooler at $370 might be a better deal. The price cuts come just before the launch of Intel's Coffee Lake processors so you might want to wait a day or so for reviews to appear. The price cuts could also signal AMD's desire to move stock before the launch of Pinnacle in a few months.
Wasn't that much more pleasant than finding out the IRS plans to crowd source their tax fraud investigations by awarding a $7m contract to Equifax who can count on everyone who grabbed your leaked personal information to do their work for them?
"They also coincide with rumours that AMD plans to launch a new series of Ryzen parts in February, based on 12nm process technology. The AMD Ryzen ‘Pinnacle' parts will be part of a shift of both CPUs and GPUs to GlobalFoundries 12nm LP [leading performance] process during 2018."

Renowned overclocker der8auer got his hands on the new 18-core Intel Core i9-7980XE and managed to break a few records with more than a bit of LN2 and thermal paste. Following a delid, der8auer slathered the bare die and surrounding PCB with a polymer-based (Kryonaut) TIM and reattached the HIS to prepare for the extreme overclock. He even attempted to mill out the middle of the IHS to achieve a balance between direct die cooling and using the IHS to prevent bending the PCB and spread out the pressure from the LN2 cooler block, but ran into inconsistent results between runs and opted not to proceed with that method.
Using an Asus Rampage VI Apex X299 motherboard and the Core i9-7980XE at an Asus ROG event in Taiwan der8auer used liquid nitrogen to push all eighteen cores (plus Hyper-Threading) to 6.1 GHz for a CPU-Z validation. To get those clockspeeds he needed to crank up the voltage to 1.55V (1.8V VCCIN) which is a lot for the 14nm Skylake X processor. Der8auer noted that overclocking was temperature limited beyond this point as at 6.1 GHz he was seeing positive temperatures on the CPU cores despite the surface of the LN2 block being as low as -100 °C! Perhaps even more incredible is the power draw of the processor as it runs at these clockspeeds with the system drawing as much as 1,000 watts (~83 amps) on the +12V rail with the CPU being responsible for almost all of that number! That is a lot of power running through the motherboard VRMs and the on-processor FIVR!
For comparison, at 5.5 GHz he measured 70 amps on the +12V rail (840W) with the chip using 1.45V vcore under load.
For Cinebench R15, the extreme overclocker opted for a tamer 5.7 GHz where the i9-7980XE achieved a multithreaded score of 5,635 points. He compared that to his AMD Threadripper overclock of 5.4 GHz where he achieved a Cinebench score of 4,514 (granted the Intel part was using four more threads and clocked higher).
To push things (especially his power supply heh) further, the overclocker added a LN2 cooled NVIDIA Titan Xp to the mix and managed to overclock the graphics card to 2455 MHz at 1.4V. With the 3840 Pascal cores at 2.455 GHz he managed to break three single card world records by scoring 45,705 in 3DMark 11, 35,782 in 3DMark Fire Strike, and 120,425 in 3DMark Vantage!
Der8auer also made a couple interesting statements regarding overclocking at these levels including the issues of cold bugs not allowing the CPU and/or GPU to boot up if the cooler plate is too cold. On the other side of things, once the chip is running the power consumption can jump drastically with more voltage and higher clocks such that even LN2 can’t maintain sub-zero core temperatures! The massive temperature delta can also create condensation issues that need to be dealt with. He mentions that while for 24/7 overclocking liquid metal TIMs are popular choices, when extreme overclocking the alloy actually works against them because the sub-zero temperatures reduce the effectiveness and thermal conductivity of the interface material which is why polymer-based TIMs are used when cooling with liquid nitrogen, liquid helium, or TECs. Also, while most people apply a thin layer of thermal paste to the direct die or HIS, when extreme overclocking he “drowns” the processor die and PCB in the TIM to get as much contact as possible with the cooler as every bit of heat transfer helps even the small amount he can transfer through the PCB. Further, FIVR has advantages such as per-core voltage fine tuning, but it also can hold back further overclocking from cold bugs that will see the processor shut down past -100 to -110 °C temperature limiting overclocks whereas with an external VRM setup they could possibly push the processor further.
For the full scoop, check out his overclocking video. Interesting stuff!

You cannot really talk about the new Skylake-X parts from Intel without bringing up AMD's Threadripper as that is the i9-7980XE and i9-7960X's direct competition. From a financial standpoint, AMD is the winner, with a price tag either $700 or $1000 less than Intel's new flagship processors. As Ryan pointed out in his review, for those whom expense is not a consideration it makes sense to chose Intel's new parts as they are slightly faster and the Xtreme Edition does offer two more cores. For those who look at performance per dollar the obvious processor of choice is ThreadRipper; for as Ars sums up in their review AMD offers more PCIe lanes, better heat management and performance that is extremely close to Intel's best.
"Ultimately, the i9-7960X raises the same question as the i9-7900X: Are you willing to pay for the best performing silicon on the market? Or is Threadripper, which offers most of the performance at a fraction of the price, good enough?"

Tagged: Z370, Intel, coffee lake
The official press deck for Coffee Lake-S was leaked to the public, so Intel gave us the go-ahead to discuss the product line-up in detail (minus benchmarks). While the chips are still manufactured on the 14nm process that Kaby Lake, Skylake, and Broadwell were produced on, there’s more on them. The line-up is as follows: Core i3 gets quad-core without HyperThreading and no turbo boosting, Core i5 gets six-core without HyperThreading but with Turbo boosting, and Core i7 gets six-core with HyperThreading and Turbo boosting.
While the slide deck claims that the CPU still has 16 PCIe 3.0 lanes, the whole platform supports up to 40. They specifically state “up to” over and over again, so I’m not sure whether that means “for Z370 boards” or if there will be some variation between individual boards. Keep in mind that only 16 lane of this are from the processor itself, the rest are simply a part of the chipset. This unchanged from Z270.
Moving on, Intel has been branding this as “Intel’s Best Gaming Desktop Processor” all throughout their presentation. The reasoning is probably two-fold. First, this is the category of processors that high-end, mainstream, but still enthusiast PC gamers target. Second, gaming, especially at super-high frame rates, is an area that AMD has been struggling with on their Ryzen platform.
Speaking of performance, the clock rate choice is quite interesting compared to Kaby Lake. In all cases, the base clock had a little dip from the previous generation, but the Turbo clock, if one exists, has a little bump. For instance, going from the Core i7-7700k to the Core i7-8700k, your base clock drops from 4.2 GHz to just 3.7 GHz, but the turbo jumps up from 4.5 GHz to 4.7 GHz. You also have a little more TDP to work with (95W vs 91W) with the 8700k. I’m not sure what this increase variance between low and high clock rates will mean, but it’s interesting to see Intel making some sort of trade-off on the back end.
(Editor's note: the base clock is only going to be a concern when running all cores for a long period of time. I fully expect performance to be higher for CFL-S parts than KBL-S parts in all workloads.)
The last thing that I’ll mention is that, of the two i3s, the two i5s, and the two i7s, one is locked (and lower TDP) and one is unlocked. In other words, Intel has an unlocked solution in all three classifications, even the i3. Even though it doesn’t have a turbo clock setting, you can still overclock it by hand if you desire.
Prices range from $117 to $359 USD, as seen in the slide, above. They launch on October 5th.

According to the Netherlands arm of Hardware.info, while Kaby Lake-based processors will physically fit into the LGA-1151 socket of Z370 motherboards, they will fail to boot. Since their post, Guru3D asked around to various motherboard manufacturers, and they claim that Intel is only going to support 8th Generation processors with that chipset via, again, allegedly, a firmware lock-out.
Thankfully, it's not Chocolate Lake.
Image credit: The Red List
If this is true, then it might be possible for Intel to allow board vendors to release a new BIOS that supports these older processors. Guru3D even goes one step further and suggests that, just maybe, motherboard vendors might have been able to support Coffee Lake on Z270 as well, if Intel would let them. I’m... skeptical about that last part in particular, but, regardless, it looks like you won’t have an upgrade path, even though the socket is identical.
It’s also interesting to think about the issue that Hardware.info experienced: the boot failed on the GPU step. The prevailing interpretation is that everything up to that point is close enough that the BIOS didn’t even think to fail.
My interpretation of the step that booting failed, however, is wondering whether there’s something odd about the new graphics setup that made Intel pull support for Z270. Also, Intel usually supports two CPU generations with each chipset, so we had no real reason to believe that Skylake and Kaby Lake would carry over except for the stalling of process tech keeping us on 14nm so long.
Still, if older CPUs are incompatible with Z370, and for purely artificial reasons, then that’s kind-of pathetic. Maybe I’m odd, but I tend to buy a new motherboard with new CPUs anyway, but I can’t envision the number of people who flash BIOSes with their old CPU before upgrading to a new one is all that high, so it seems a little petty to nickel and dime the few that do, especially at a time that AMD can legitimately call them out for it.
There has to be a reason, right?

Phoronix have been hard at work testing out AMD's new server chip, specifically the 2.2/2.7/3.2GHz EPYC 7601 with 32 physical cores. The frequency numbers now have a third member which is the top frequency all 32 cores can hit simultaneously, for this processor that would be 2.7GHz. Benchmarking server processors is somewhat different from testing consumer CPUs, gaming performance is not as important as dealing with specific productivity applications. Phoronix started their testing of EPYC, in both NUMA and non-NUMA configurations, comparing against several Xeon models and the performance delta is quite impressive, sometimes leaving even a system with dual Xeon Gold 6138's in the dust. They also followed up with a look at how EPYC compares to Opteron, AMD's last server offerings. The evolution is something to behold.
"By now you have likely seen our initial AMD EPYC 7601 Linux benchmarks. If you haven't, check them out, EPYC does really deliver on being competitive with current Intel hardware in the highly threaded space. If you have been curious to see some power numbers on EPYC, here they are from the Tyan Transport SX TN70A-B8026 2U server. Making things more interesting are some comparison benchmarks showing how the AMD EPYC performance compares to AMD Opteron processors from about ten years ago."

Initially launched in August of 2015, the Skylake consumer desktop processors are finally ramping down at Intel production facilities. Based on this Intel Product Change Notification, the widely coveted Core i7-6700K and Core i5-6600K, along with several other parts, are being EOL'd (end of life).
If you are an OEM or just really love building around these parts, you still have some time to get your orders in. You have until March 30, 2018 to place your final requests and the final shipment date will be a year from today. If you ever were curious how complex the ramp down on parts that ship to thousands of different customers in consumer, enterprise, and embedded markets, the table above should give you a glimpse.
(Probably that 3017 date is a typo...)
With the focus for Intel squarely on the Kaby Lake Core i7-7700K and Core i5-7600K, in addition to the upcoming Coffee Lake refresh 8000-series, enthusiasts might be wondering why it took Intel so long to shut things down on this set of Skylake parts.
I think it is safe to say that this marks the end of an interesting window of time for Intel, where it had clear and uncontested dominance of the consumer processor market. Re-reading my conclusion to the 6700K review reveals almost no mention of a relevant AMD competing part, making today's situation with Ryzen and Threadripper all the more impressive.

We are just starting to ramp back up here after the long holiday weekend, so let's start with something that is both interesting and easy to absorb. High-profile overclocker Der8auer has gotten his hands on an 18-core Skylake-X processor and did exactly what you would expect - delidded it.
The takeaway from this is two-fold. First, the die appears very clean, indicating that Intel has still not decided to solder these high-end processors and is going with a standard thermal interface between the die and the heat spreader.
Also...it's friggin huge. Look at the 10-core die from the Core i9-7900X that was observed earlier this year and compare it to the image above.
Though the camera angles aren't ideal, comparing the layout of the die to the physical substrate, which IS the same size between all the Skylake-X processors, you can see how much larger this 18-core die truly is. Expect to see the 18, 16, 14, and even the 12-core processors to use the same physical die.

Intel has officially announced their new workstation processor lineup, with Xeon Scalable and Xeon W versions aimed at both professional and mainstream workstation systems.
"Workstations powered by Intel Xeon processors meet the most stringent demands for professionals seeking to increase productivity and rapidly bring data to life. Intel today disclosed that the world-record performance of the Intel Xeon Scalable processors is now available for next-generation expert workstations to enable photorealistic design, modeling, artificial intelligence (AI) analytics, and virtual-reality (VR) content creation."
The first part of Intel’s product launch announcement are the new Xeon Scalable processors, first announced in July, and these are dual-socket solutions targeting professional workstations. Versions with up to 56 cores/112 threads are available, and frequencies of up to 4.20 GHz are possible via Turbo Boost. Intel is emphasising the large performance impact of upgrading to these new Xeon processors with a comparison to older equipment (a trend in the industry of late), which is relevant when considering the professional market where upgrades are far slower than the enthusiast desktop segment:
“Expert workstations will experience up to a 2.71x boost in performance compared to a 4-year-old system and up to 1.65x higher performance compared to the previous generation.”
The second part of announcement are new Xeon W processors, which will be part of Intel’s mainstream workstation offering. These are single-socket processors, with up to 18 cores/36 threads and Turbo Boost frequencies up to 4.50 GHz. The performance impact with these new Xeon W CPUs compared to previous generations is not as great as the Xeon Scalable processors above, as Intel offers the same comparison to older hardware with the Xeon W:
“Mainstream workstations will experience up to a 1.87x boost in performance compared to a 4-year-old system4 and up to 1.38x higher performance compared to the previous generation.”

As you can see from the picture, new habits will need to e learned when spreading the TIM on such a large area so keep an eye out for tips or carefully experiment on your own. The heatsink let [H] reach a solid 4GHz on all 16 cores with a 3200MHz memory clock, at significantly lower voltages than Ryzen required to reach the same frequency. Even better news is that this is not the limit, [H] intends to test again using a more powerful radiator and expects to see an even better overclock.
"XSPC got us over one of its first waterblocks specifically designed to help handle Ryzen Threadripper CPU's heat while overclocking. We give you a quick unboxing, break down the block itself, and then we look at Threadripper long-term performance. We finally get it dialed in at 4GHz."

When you look at the results Ryan posted, it was clear that when it comes to video rendering and other content creation it is AMD's chip which comes out ahead in performance, and at a better price point that Intel's Core i9. Don't just take our word for it, many others reviewed the new chips, including [H]ard|OCP. Their results agree, showing that the only advantage Intel has is in single threaded applications, in which case the frequency of the 4.6GHz Intel part can outpace the 4GHz Threadripper. Those picking up Threadripper have no interest in single threaded applications, they prefer their programs to be spread across multiple cores and not only does Threadripper have the most cores, it allows you to flip between NUMA and UMA depending on your preference. Check out [H]'s review here before continuing below the fold.
"The day is finally upon us that many CPU enthusiasts have been waiting for. We get to see what AMD's new Threadripper CPU is all about in terms of performance, and in attempts to cool the beast. There has been no lack of hype for months now, so let's see if it is all justified."

It has been a long time since lapping was a requirement to get the best cooling for your new processor, however it might be making a comeback. Threadripper is endowed with a larger heatsink than your average CPU and to help you accommodate that the chip contains an Asetek mounting bracket which is compatible with most AiO coolers. The bracket and size of the heatspreader do seem to exacerbate any curvature of the coldplate however, the Asetek AiO which [H]ard|OCP tested needed to be lapped for a proper mating.
Since they had some difficulty with AiO coolers, [H] decided to configure their own watercooler for Threadripper. They grabbed an old Koolance water block they had handy and with a bit of time and a $10 trip to a hardware store they ended up with a much better solution. Take peek at the process, especially if you happen to have parts lying around that you want to put back to use.
"What do you do when you don't have the proper parts that you need to water cool your new thread ripper? Make you own with trash you find around the house. Maybe even repurpose and old water block that is in your closet."

Intel launched the first half of its X-Series processor lineup earlier this year, releasing up to the 10-core i9-7900X. But with the upcoming release of AMD's 16-core Threadripper 1950X, the real interest among enthusiasts are the specs of Intel's high core count X-Series parts.
After previously teasing partial specs for these parts, Intel today finally unveiled the complete details, starting out with the i9-7920X (12 cores/24 threads) with a 2.9GHz base and up to 4.4GHz boost clock and topping out with the i9-7980XE (18 cores/36 threads) with a 2.6GHz base and 4.4GHz max boost clock. Check the table below for the complete specifications:
|i9-7980XE||i9-7960X||i9-7940X||i9-7920X||i9-7900X||i7-7820X||i7-7800X||TR 1950X||TR 1920X||TR 1900X|
|Base Clock||2.6 GHz||2.8 GHz||3.1 GHz||2.9 GHz||3.3 GHz||3.6 GHz||3.5 GHz||3.4 GHz||3.5 GHz||3.8 GHz|
|Turbo Boost 2.0||4.2 GHz||4.2 GHz||4.3 GHz||4.3 GHz||4.3 GHz||4.3 GHz||4.0 GHz||4.0 GHz||4.0 GHz||4.0 GHz|
|Turbo Boost Max 3.0||4.4 GHz||4.4 GHz||4.4 GHz||4.4 GHz||4.5 GHz||4.5 GHz||N/A||N/A||N/A||N/A|
|DDR4-2666 Quad Channel||DDR4-2666 Quad Channel|
|TDP||165 watts||165 watts||165 watts||140 watts||140 watts||140 watts||140 watts||180 watts||180 watts||180 watts?|
From a pure core-count perspective, the Threadripper 1950X goes up against Intel's i9-7960X, but with a $700 difference in price. With Intel CPUs holding and IPC advantage over AMD, however, it's likely that the i9-7920X, and perhaps even the 7900X, will best Threadripper in certain gaming and productivity workloads.
Also interesting in Intel's announcement today are the base clocks of the 12-core i9-7920X (2.9GHz) and the 14-core i9-7940X (3.1GHz). Intel pushed the TDP of the 7940X to 165W, allowing it to increase the base clock over its 12-core counterpart. This suggests that Intel expects the 14-core 7940X, at a price-point of $1399, to be a popular choice in terms of price-to-performance.
Finally, Intel's release today reveals that all of the upcoming X-Series parts will have 44 PCIe lanes, compared to the 64 lanes AMD is offering on all Threadripper parts. There was some debate in the office this morning about how Intel's 44 lanes should cover most configurations for the foreseeable future, but this still remains one clear advantage for AMD's platform.
Intel's 4- to 10-core processors are already on the market. Intel says that the 12-core 7920X will launch August 28th, while the 14- to 18-core parts will launch about a month later, on September 25th.

You may have heard that Intel's upcoming 8th-generation processors, code named Coffee Lake, won't be compatible with the current Z270 chipset motherboards. Last week we had another round of rumors and reports about these upcoming - and totally incompatible - new CPUs, with wccftech reporting some details on what to expect with the new processors. Spoiler: MORE CORES.

We begin with the Intel Core i7-8700K, which will reportedly be the company's first mainstream 6-core processor, with previous hex-core offerings limited to HEDT and server. The i7-8700K will run slightly below the current 4-core i7-7700K, with a base frequency of 3.7 GHz (vs. 4.2 GHz with the i7-7700K) and single-core Turbo speeds topping out at 4.3 GHz according to the report. Another point of interest with the 6-core i7 part is TDP, with 95W needed where even the current HEDT parts are into the 130W territory. What of the Core i5? This is where things get a little more interesting, as there appear to be 6-core parts in the i5 family as well, without Hyper-Threading of course. Even the Core i3 parts jump to 4-core configurations with Coffee Lake, which would obviously be another first.

To editoralize a bit, AMD seems to be in a highly influential position in the wake of Ryzen and Threadripper, as Intel is (reportedly, of course) upping the core counts for Core series processors. Sure, Intel could have done this anyway, but looking at their pre-Ryzen products they were quite happy selling 2 - 4 core parts for premium prices before. This is great news for anyone in an era of increasingly multi-thread optimized computing (as long as pricing remains at or below current offerings), and with this healthy competition the second half of the year might be the best time in a very long time to upgrade - be it Intel or AMD. Now, if only graphics cards would fall back down to earth...
