The open source API, Vulkan, just received a big birthday present from Intel as they added official support on their Skylake and Kaby Lake CPUs under Windows 10. We have seen adoption of this API from a number of game engine designers, Unreal Engine and Unity have both embraced it, the latest DOOM release was updated to support Vulkan and there is even a Nintendo 64 renderer which runs on it. Ars Technica points out that both AMD and NVIDIA have been supporting this API for a while and that we can expect to see Android implementations of this close to the metal solution in the near future.
"After months in beta, Intel's latest driver for its integrated GPUs (version 188.8.131.5290) adds support for the low-overhead Vulkan API for recent GPUs running in Windows 10. The driver supports HD and Iris 500- and 600-series GPUs, the ones that ship with 6th- and 7th-generation Skylake and Kaby Lake processors."

Yesterday EE Times posted some interesting information that they had gleaned at ISSCC. AMD released a paper describing the design process and advances they were able to achieve with the Zen architecture manufactured on Samsung’s/GF’s 14nm FinFETT process. AMD went over some of the basic measurements at the transistor scale and how it compares to what Intel currently has on their latest 14nm process.
The first thing that jumps out is that AMD claimes that their 4 core/8 thread x86 core is about 10% smaller than what Intel has with one of their latest CPUs. We assume it is either Kaby Lake or Skylake. AMD did not exactly go over exactly what they were counting when looking at the cores because there are some significant differences between the two architectures. We are not sure if that 44mm sq. figure includes the L3 cache or the L2 caches. My guess is that it probably includes L2 cache but not L3. I could be easily wrong here.
Going down the table we see that AMD and Samsung/GF are able to get their SRAM sizes down smaller than what Intel is able to do. AMD has double the amount of L2 cache per core, but it is only about 60% larger than Intel’s 256 KB L2. AMD also has a much smaller L3 cache as well than Intel. Both are 8 MB units but AMD comes in at 16 mm sq. while Intel is at 19.1 mm sq. There will be differences in how AMD and Intel set up these caches, and until we see L3 performance comparisons we cannot assume too much.

In some of the basic measurements of the different processes we see that Intel has advantages throughout. This is not surprising as Intel has been well known to push process technology beyond what others are able to do. In theory their products will have denser logic throughout, including the SRAM cells. When looking at this information we wonder how AMD has been able to make their cores and caches smaller. Part of that is due to the likely setup of cache control and access.
One of the most likely culprits of this smaller size is that the less advanced FPU/SSE/AVX units that AMD has in Zen. They support AVX-256, but it has to be done in double the cycles. They can do single cycle AVX-128, but Intel’s throughput is much higher than what AMD can achieve. AVX is not the end-all, be-all but it is gaining in importance in high performance computing and editing applications. David Kanter in his article covering the architecture explicitly said that AMD made this decision to lower the die size and power constraints for this product.
Ryzen will undoubtedly be a pretty large chip overall once both modules and 16 MB of L3 cache are put together. My guess would be in the 220 mm sq. range, but again that is only a guess once all is said and done (northbridge, southbridge, PCI-E controllers, etc.). What is perhaps most interesting of it all is that AMD has a part that on the surface is very close to the Broadwell-E based Intel i7 chips. The i7-6900K runs at 3.2 to 3.7 GHz, features 8 cores and 16 threads, and around 20 MB of L2/L3 cache. AMD’s top end looks to run at 3.6 GHz, features the same number of cores and threads, and has 20 MB of L2/L3 cache. The Intel part is rated at 140 watts TDP while the AMD part will have a max of 95 watts TDP.
If Ryzen is truly competitive in this top end space (with a price to undercut Intel, yet not destroy their own margins) then AMD is going to be in a good position for the rest of this year. We will find out exactly what is coming our way next month, but all indications point to Ryzen being competitive in overall performance while being able to undercut Intel in TDPs for comparable cores/threads. We are counting down the days...

[H]ard|OCP followed up their series on replacing the TIM underneath the heatspreader on Kaby Lake processors with another series depicting the i5-7600K in the buff. They removed the heatspreader completely and tried watercooling the die directly. As you can see in the video this requires more work than you might immediately assume, it was not simply shimming which was involved, some of the socket on the motherboard needed to be trimmed with a knife in order to get the waterblock to sit directly on the core. In the end the results were somewhat depressing, the risks involved are high and the benefits almost non-existent. If you are willing to risk it, replacing the TIM and reattaching the heatspreader is a far better choice.
"After our recent experiments with delidding and relidding our 7700K and 7600K to see if we could get better operating temperatures, we decided it was time to go topless! Popping the top on your CPU is one thing, and getting it to work in the current processor socket is another. Get out your pocket knife, we are going to have to make some cuts."

Recently [H]ard|OCP popped the lid off of an i7-7700k to see if the rumours that once again Intel did not use high quality thermal interface material underneath the heatspreader. The experiment was a success in one way, the temperatures dropped 25.28%, from 91C to 68C. However the performance did not change much, they still could not reach a stable 5GHz overclock. They did not let that initial failure discourage them and spent some more time with their enhanced Kaby Lake processor to find scenarios in which they could reach or pass the 5GHz mark. They met with success when they reduced the RAM frequency to 2666MHz, by disabling Hyperthreading they could reach 5GHz with 3600MHz RAM but only when they increased the VCore did they manage to break 5GHz.
Of course you must exercise caution when tweaking to this level, a higher VCore will certainly reduce the lifespan of your chip and delidding can have a disastrous outcome even if done carefully. If you are interested in trying this, The Tech Report has a link to a 3D printed tool to help you in your endeavours.
"Last week we shared our overclocking results with our retail purchased Core i7-7700K Kaby Lake processor. We then took the Integrated Heat Spreader off, replaced the Thermal Interface Material and tried again for 5GHz with 3600MHz memory and failed. This time, less RAM MHz and more core voltage!"

With the latest revision of the TUF line, ASUS made the decision to drop the well-known "Sabertooth" moniker from the board name, naming the board's with the TUF branding only. The TUF Z270 Mark 1 motherboard is the flagship board in ASUS' TUF (The Ultimate Force) product line designed with the Intel Z270 chipset. The board offers support for the latest Intel Kaby Lake processor line as well as Dual Channel DDR 4 memory because of its integrated Intel Z270 chipset. While the MSRP for the board may be a bit higher than expected, its $239 price is more than justified by the board's build quality and "armored" offerings.

The TUF Z270 Mark 1 motherboard is built with the same quality and attention to detail that you've come to expect from TUF-branded motherboards. Its appearance follows the standard tan plastic armor overlay on the top with a 10-phase digital power system. The board contains the following integrated features: six SATA 3 ports; two M.2 PCIe x4 capable ports; dual GigE controllers - an Intel I219-V Gigabit NIC and an Intel I211 Gigabit NIC; three PCI-Express x16 slots; three PCI-Express x1 slots; an 8-channel audio subsystem; MEM OK! and USB BIOS Flashback buttons; integrated DisplayPort and HDMI; and USB 2.0, 3.0, and 3.1 Type-A and Type-C port support.

Not too long ago the release of a new processor family meant a noticeable improvement from the previous generation and the only question was how to upgrade, not if you should upgrade. Like many other things, that has passed on into the proverbial good old days and now we need reviews like this one published by [H]ard|OCP. Is there any noticeable performance difference between the two chips outside of synthetic benchmarks?
The test systems are slightly different as the memory has changed, the 7700K has 2666MHz DDR4 while the 2600K has 2133MHz DDR3; both CPUs are clocked at 4.5GHz however. Their results show actual performance deltas in productivity software such as HandBrake and Blender, justifying the upgrade for those who focus on content creation. As for gaming, if you have no GPU then you will indeed see performance increases; but nothing compared to buying a GPU.
"There are many HardOCP readers that are still running Sandy Bridge CPUs and have been waiting with anticipation of one day upgrading to a new system. One of the biggest things asked in the last month is just how the 2600K stacks up against the new 7700K processor. So we got hold of one of our readers 2600K systems and put it to the test."

Gigabyte had a full line of new laptops to show off at this year’s CES, with models ranging from larger gaming enthusiast designs to slim machines that still offer plenty of gaming power from their discrete graphics.
We’ll start with the P56, a 15.6-inch machine with an optional 4K display, 7th-gen Intel Core i7 (Kaby Lake) processor, and GeForce GTX 1070 GPU.
“The P56 provides enthusiasts with not only ultra smooth performance but also with tools to victory. All packed in a portable quality chassis. Equipped with the next gen Intel 7th Gen Core i7 7700HQ processor and the all-powerful GeForce GTX 1070 graphics. The main core of the P56 is set to drive all the latest games, not at just 1080P but even at higher resolutions with the optional 15.6” UHD 3840x2160 display.”
The P56 is equipped with a Thunderbolt 3 port, island-style keyboard with customizable per-key RGB backlighting, and a large 91Wh battery.
Next we have the Sabre 15, which is also powered by a new 7th-gen Intel Core i7 processor, with NVIDIA GeForce GTX 1050 Ti (4GB) and GTX 1050 (2GB) graphics options.
“Gamers can now fully enjoy the latest performance from the pascal architecture, with fluid gaming graphics at 1080p for most recent game titles. The keyboard plays a big role in winning or losing a game, that is why the Sabre 15 comes with optimized 2.2mm travel scissor type keys, for that extra feel and precision. To top that off, the Sabre 15 features RGB backlight keyboard with 16.8 million colors (optional).”
Rounding out the updated lineup are a trio of thin-and-light professional models that are still very capable gaming machines, beginning with the AERO 14, a 19.9mm-thick (and 4.17 lb) aluminum design which features a QHD (2560x1440) IPS screen, GeForce GTX 1060 GPU, and 94.24Wh battery.
Finally we have the P34 and P35 laptops, which claim the title of “world’s lightest 14” GeForce GTX 1050 Ti laptop (P34) and “world’s slimmest 15.6” GeForce GTX 1070 laptop”, respectively.
The P34 is indeed light for a gaming-ready laptop, with a weight of just 3.73 lbs. For its part the 15.6-inch P35 laptop is a very high-end option, regardless of its slim construction.
“The P35 comes in at an unbeatable 20.9mm thin and weighs just 2.3Kg. It is hard to believe that such a thin chassis has a GeForce GTX 1070 inside, outputting the same performance as the desktop GeForce GTX 1070, now on the go. GIGABYTE has swapped out the old 6th gen and opt for the latest 7th gen Core i7 processor, giving professionals multitasking capabilities like never before. The unparalleled graphical power of the GeForce GTX 1070 further drives the stunning 15.6” UHD 3840 x 2160 IPS display, professionals will definitely take advantage of such a high pixel density and high RGB accuracy display, stationed or mobile. The Swappable bay gives professionals the power to swap between Blu-ray drive or up to 2TB HDD of extra storage, providing that extra customization on the go.”
Pricing and availability information for the new laptops is not yet available.
