Today's Intel leak is a little less of a rumour than the AMD GPUs of yesterday as Intel accidentally published the model information themselves. The process node, price and any release dates are speculation but we do have specs on two 9th generation Core processors. The i5-9600K will be a six core, six thread CPU with top clock of 4.5GHz, 9MB of L3 cache and a 95W TDP. The other model revealed is the i3-9000 will have four 3.7GHz cores with 4 threads, 6MB of L3 cache and a 65W TDP. These Coffee Lake Refresh chips will a tough time on the market as AMD offers higher thread counts, albeit at a lower frequency.
Things are getting very interesting in the CPU world; The Inquirer has links if you want to dig.
"The document appears to have now been updated to strip out mention of the 9th-gen processors, but PC Gamer reports that a separate PDF was also posted online - though it now results in a page missing error - that listed some of the specs of the incoming chips."

2018: A banner year
Intel has a long history of generating tremendous amounts of revenue and income. This latest quarter is no exception. Intel has announced record Q1 revenues for this year and they look to continue that trend throughout 2018. AMD released their very positive results yesterday, but their finances are dwarfed by what Intel has brought to market. The company had revenue of $16.1 billion with a net income of $4.5 billion. Compare this to AMD’s $1.625B revenue and $81M net income we see that the massive gulf between these two companies will not be bridged anytime soon with either Intel falling or AMD gaining.
Intel has put its money to good use with a wide variety of products that stretch between the PC market and datacenters. While their low power and ultra-mobile strategies have been scaled back and cancelled in some cases, their core markets are unaffected and they continue to make money hand over fist. The company has always been fundamentally sound in terms of finances and they do not typically spend money recklessly. They continue to feature market leading IPC with their product lines and can address multiple markets with the x86 products they have.

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!

If the rumours are true, the new 14nm Raven Ridge based AMD Ryzen 5 2500U will offer an impressive jump in performance compared to AMD's current generation of APUs. The Inquirer's source suggests the new APU will offer a 50% jump in single threaded performance and an impressive 90% advantage on multi-threaded performance. The multithreaded performance improvement may be the headline but seeing a huge increase in single threaded applications, AMD's recent Achilles Heel, shows some interesting improvements to Zen. This will also mark the arrival of their first APU with Vega onboard, so you can expect better graphics performance as well. The benchmark numbers and links are here.
"LEAKED BENCHMARKS for AMD's forthcoming Raven Ridge APUs suggest that upcoming devices, expected to be launched in time for Christmas, will outperform current Bristol Ridge APUs by up to 90 per cent on multicore applications."

Tagged: Intel, goldmont+, gemini lake, apollo lake, 14nm
Information recently leaked on the successor to Intel’s low power Apollo Lake SoCs dubbed Gemini Lake. Several sites via FanlessTech claim that Gemini Lake will launch by the end of the year and will be the dual and quad core processors used to power low cost notebooks, tablets, 2-in-1 convertibles, and SFF desktop and portable PCS.
A leaked Intel roadmap.
Gemini Lake appears to be more tick than tock in that it uses a similar microarchitecture as Apollo Lake and relies mainly on process node improvements with the refined 14nm+ process to increase power efficiency and performance per watt. On the CPU side of things, Gemini Lake utilizes the Goldmont+ microarchitecture and features two or four cores paired with 4MB of L2 cache. Intel has managed to wring higher clockspeeds while lowering power draw out of the 14nm process. A doubling of the L2 cache versus Apollo Lake will certainly give the chip a performance boost. The SoC will use Intel Gem9 graphics with up to 18 Execution Units (similar to Apollo Lake) but the GPU will presumably run at higher clocks. Additionally, the Gemini Lake SoC will integrate a new single channel DDR4 memory controller that will support higher memory speeds, s WLAN controller (a separate radio PHY is still required on the motherboard) supporting 802.11 b/g/n and Bluetooth 4.0.
Should the leaked information turn out to be true, he new Gemini Lake chips are shaping up to be a good bit faster than their predecessor while sipping power with TDPs of up to 6W for mobile devices and 10W for SFF desktop.
The lower power should help improve battery life a bit which is always a good thing. And if they can pull off higher performance as well all the better!
Unfortunately, it is sounding like Gemini Lake will not be ready in te for the back to school or holiday shopping seasons this year. I expect to see a ton of announcements on devices using the new SoCs at CES though!

At Intel's Technology and Manufacturing Day event in San Francisco there was a lot of talk about how Intel's 14nm process technology compares to the 16nm, 14nm, and 10nm offerings of their competitors. Investors and enthusiasts are curious if Intel can hold their lead in process tech as Samsung seems to be on track to release chips fabbed on 10nm process before Intel will. Intel rightly pointed out that not all process tech is measured the same way and that pitch measurements give only one part of the picture; meaning Samsung might not actually be smaller than them.
The Tech Report were present at that meeting and have written up an in depth look at what Intel means when they dispute the competitions claims, as well as their rationale behind their belief that the 14nm node still has a lot of life left in it.
"As process sizes grow smaller and smaller, Intel believes that the true characteristics of those technology advances are being clouded by an over-reliance on a single nanometer figure. At its Technology and Manufacturing Day this week, the company defended its process leadership and proposed fresh metrics that could more accurately describe what a given process is capable of."

Having already familiarized yourself with Intel's new Kaby Lake architecture and the i7-7700k processor in Ryan's review you may now be wondering how well the new CPU overclocks for others. [H]ard|OCP received three i7-7700k's and three different Z270 motherboards for testing and they set about overclocking these in combination to see what frequency they could reach. Only one of the chips was ever stable at 5GHz, and it is reassuring that it managed that on all three motherboards, the remaining two would only hit 4.8GHz which is still not a bad result. Drop by to see their settings in full detail.
"After having a few weeks to play around with Intel's new Kaby Lake architecture Core i7-7700K processors, we finally have some results that we want to discuss when it comes to overclocking and the magic 5GHz many of us are looking for, and what we think your chances are of getting there yourself."

It probably doesn't surprise any of our readers that there has been a tepid response to the leaks and reviews that have come out about the new Core i7-7700K CPU ahead of the scheduled launch of Kaby Lake-S from Intel. Replacing the Skylake-based 6700K part as the new "flagship" consumer enthusiast CPU, the 7700K has quite a bit stacked against it. We know that Kaby Lake is the first in the new sequence of tick-tock-optimize, and thus there are few architectural changes to any portion of the chip. However, that does not mean that the 7700K and Kaby Lake in general don't offer new capabilities (HEVC) or performance (clock speed).
The Core i7-7700K is in an interesting spot as well with regard to motherboards and platforms. Nearly all motherboards that run the Z170 chipset will be able to run the new Kaby Lake parts without requiring an upgrade to the newly released Z270 chipset. However, the likelihood that any user on a Z170 platform today using a Skylake processor will feel the NEED to upgrade to Kaby Lake is minimal, to say the least. The Z270 chipset only offers a couple of new features compared to last generation, so the upgrade path is again somewhat limited in excitement.
Let's start by taking a look at the Core i7-7700K and how it compares to the previous top-end parts from the consumer processor line and then touch on the changes that Kaby Lake brings to the table.
With the beginning of CES just days away (as I write this), Intel is taking the wrapping paper off of its first gift of 2017 to the industry. As you can see from the slide above, more than just the Kaby Lake-S consumer socketed processors are launching today, but other components including Iris Plus graphics implementations and quad-core notebook implementations will need to wait for another day.
For DIY builders and OEMs, Kaby Lake-S, now known as the 7th Generation Core Processor family, offer some changes and additions. First, we will get a dual-core HyperThreaded processor with an unlocked designation in the Core i3-7350K. Other than the aforementioned Z270 chipset, Kaby Lake will be the first platform compatible with Intel Optane memory. (To be extra clear, I was told that previous processors will NOT be able to utilize Optane in its M.2 form factor.)
Though we have already witnessed Lenovo announcing products using Optane, this is the first official Intel discussion about it. Optane memory will be available in M.2 modules that can be installed on Z270 motherboards, improving snappiness and responsiveness. It seems this will be launched later in the quarter as we don't have any performance numbers or benchmarks to point to demonstrating the advantages that Intel touts. I know both Allyn and I are very excited to see how this differs from previous Intel caching technologies.
