Application Profiling Tells the Story
It should come as no surprise to anyone that has been paying attention the last two months that the latest AMD Ryzen processors and architecture are getting a lot of attention. Ryzen 7 launched with a $499 part that bested the Intel $1000 CPU at heavily threaded applications and Ryzen 5 launched with great value as well, positioning a 6-core/12-thread CPU against quad-core parts from the competition. But part of the story that permeated through both the Ryzen 7 and the Ryzen 5 processor launches was the situation surrounding gaming performance, in particular 1080p gaming, and the surprising delta that we see in some games.
Our team has done quite a bit of research and testing on this topic. This included a detailed look at the first asserted reason for the performance gap, the Windows 10 scheduler. Our summary there was that the scheduler was working as expected and that minimal difference was seen when moving between different power modes. We also talked directly with AMD to find out its then current stance on the results, backing up our claims on the scheduler and presented a better outlook for gaming going forward. When AMD wanted to test a new custom Windows 10 power profile to help improve performance in some cases, we took part in that too. In late March we saw the first gaming performance update occur courtesy of Ashes of the Singularity: Escalation where an engine update to utilize more threads resulted in as much as 31% average frame increase.
As a part of that dissection of the Windows 10 scheduler story, we also discovered interesting data about the CCX construction and how the two modules on the 1800X communicated. The result was significantly longer thread to thread latencies than we had seen in any platform before and it was because of the fabric implementation that AMD integrated with the Zen architecture.
This has led me down another hole recently, wondering if we could further compartmentalize the gaming performance of the Ryzen processors using memory latency. As I showed in my Ryzen 5 review, memory frequency and throughput directly correlates to gaming performance improvements, in the order of 14% in some cases. But what about looking solely at memory latency alone?

Microsoft has announced their new Surface Laptop, which notably leaked just yesterday, but the surprising part was not the hardware at all - however sleek and impressive it might be. Yes, it seems I spoke too soon with the Windows 10 S news, as this consumer (I assume) product is shipping with that new version of the OS which only allows apps to be installed from the Windows Store.
As to the hardware, it is milled from a block of aluminum (as shown in a very Apple-like video) and the heat pipes for the processor are milled into the bottom case to help make this so thin, but the laptop will undoubtedly feel warm to the touch during use (a fact which was mentioned on stage as a positive thing). The palmrest/keyboard is coated in a fabric material called Alcantara, rather than being bare metal and plastic. The combination of warmth (literally) and the fabric surface is supposed to make the new laptop feel very friendly, as the narrative went.
Thankfully (in my opinion, anyway) the bizarre flexible hinge of the prior Surface laptop is gone in favor of a conventional one - and with it the air gap from he previous design. Among the features mentioned for this new Surface were its PixelSense screen, which is the “thinnest LCD touch panel ever in a laptop”, and a very impressive 14.5 hour battery life. The standby power consumption was described as effectively zero, which suggests that a suspend state of some kind is standard to prevent drain when not in use. rather than a low-power sleep.

I will briefly editorialize here to mention the Windows 10 S problem here. That limitation might make sense for education, if Microsoft is providing a suite of apps that make sense for a school, but consumers will undoubtedly want more flexibility from their own devices. This is less consumer-friendly than even the Starter Edition of Windows from the past, which limited the number of running applications but not their provenance.

Microsoft has announced their first all-in-one PC with the Surface Studio, and it looks like Apple has some serious competition on their hands in the high-end AIO workstation space. Outfitted with the highest resolution display this side of Cupertino, 6th-generation Intel Skylake processors, and discrete NVIDIA graphics, there is plenty of power for most users (though gamers will clearly be looking elsewhere). Make no mistake, this new AIO from Microsoft is not going to replace a standard desktop for most people due to the $2999+ price tag, but for creative professionals and other workstation users it is a compelling option.
"Expanding the Surface family, Surface Studio is a new class of device that transforms from a workstation into a powerful digital canvas, unlocking a more natural and immersive way to create on the thinnest LCD monitor ever built.1 With a stunning ultra-HD 4.5K screen, Surface Studio delivers 63 percent more pixels than a state-of-the-art 4K TV. Surface Studio works beautifully with pen, touch and Surface Dial — a new input device designed for the creative process that lets you use two hands on the screen to compose and create in all new ways."
The star of the show is the 28-inch PixelSense display, which boasts a massive 4500x3000 resolution for a pixel density of 192 ppi, and the taller 3:2 aspect ratio will be welcomed by some users as well. Microsoft is using 10-bit panels for this premium AIO offering, and color reproduction should be outstanding with the Surface Studio thanks to "individually color calibrated" displays. Another advantage for creative customers is the display's multi-touch capability and 1024 pressure-level Surface Pen, which makes this a very nice option for digital artists - especially at 28 inches/192 ppi.
Touchscreen desktops need display placement flexibility to be useful, and here Microsoft has a "zero gravity" hinge to allow for easy movement. The design looks stable thanks to a pair of arms connecting the display to the base, and this lower half is what actually houses the PC components. What's inside? Here's a look at the official specs:
- Screen: 28” PixelSense™ Display
- Resolution: 4500 x 3000 (192 PPI)
- Color settings: Adobe sRGB and DCI-P3, individually color calibrated
- Touch: 10 point multi-touch
- Aspect Ratio: 3:2
- Supports Pen enabled and Zero Gravity Hinge
- Processor: 6th Generation Intel® Core™ i5 or i7

You have seen our take on the impressively powerful and extremely expensive i7-6950X but of course we were not the only ones to test out Intel's new top of the line processor. Hardware Canucks focused on the difference between the ~$1700 i7-6950X and the ~$1100 i7-6900K. From synthetic benchmarks such as AIDA through gaming at 720p and 1080p, they tested the two processors against each other to see when it would make sense to spend the extra money on the new Broadwell-E chip. Check out what they thought of the chip overall as well as the scenarios where they felt it would be full utilized.
"10 cores, 20 threads, over $1700; Intel's Broadwell-E i7-6950X delivers obscene performance at an eye-watering price. Then there's the i7-6900K which boasts all the same niceties in a more affordable package."

It has been nearly two years since the release of the Haswell-E platform, which began with the launch of the Core i7-5960X processor. Back then, the introduction of an 8-core consumer processor was the primary selling point; along with the new X99 chipset and DDR4 memory support. At the time, I heralded the processor as “easily the fastest consumer processor we have ever had in our hands” and “nearly impossible to beat.” So what has changed over the course of 24 months?
Today Intel is launching Broadwell-E, the follow up to Haswell-E, and things look very much the same as they did before. There are definitely a couple of changes worth noting and discussing, including the move to a 10-core processor option as well as Turbo Boost Max Technology 3.0, which is significantly more interesting than its marketing name implies. Intel is sticking with the X99 platform (good for users that might want to upgrade), though the cost of these new processors is more than slightly disappointing based on trends elsewhere in the market.
This review of the new Core i7-6950X 10-core Broadwell-E processor is going to be quick, and to the point: what changes, what is the performance, how does it overclock, and what will it cost you?

As reported by CPU World Intel has added a total of eight new processors to the 5th-gen “Broadwell” and 6th-gen “Skylake” CPU lineups, with new mobile and desktop models appearing in Intel’s price lists. The models include Core and Celeron, and range from dual core (five with Hyper-Threading) to a new quad-core i5:
Chart of new Intel models from CPU-World
“Intel today added 8 new Broadwell- and Skylake-based microprocessors to the official price list. New CPUs have unusual model numbers, like i5-6402P and i5-5200DU, which indicates that they may have different feature-set than the mainstream line of desktop and mobile CPUs. Intel also introduced today Celeron 3855U and 3955U ultra-low voltage models.”
It is unclear if the desktop models (Core i3-6098P, Core i5-6402P) listed with enter the retail channel, or if they are destined for OEM applications. The report points out these models have a P suffix “that was used to signify the lack of integrated GPU in older generations of Core i3/i5 products. There is a good chance that it still means just that”.
It comes after 8, but before 10
As the week of Intel’s Developer Forum (IDF) begins, you can expect to see a lot of information about Intel’s 6th Generation Core architecture, codenamed Skylake, finally revealed. When I posted my review of the Core i7-6700K, the first product based on that architecture to be released in any capacity, I was surprised that Intel was willing to ship product without the normal amount of background information for media and developers. Rather than give us the details and then ship product, which has happened for essentially every consumer product release I have been a part of, Intel did the reverse: ship a consumer friendly CPU and then promise to tell us how it all works later in the month at IDF.
Today I came across a document posted on Intel’s website that dives into very specific detail on the new Gen9 graphics and compute architecture of Skylake. Details on the Core architecture changes are not present, and instead we are given details on how the traditional GPU portion of the SoC has changed. To be clear: I haven’t had any formal briefing from Intel on this topic or anything surrounding the architecture of Skylake or the new Gen9 graphics system but I wanted to share the details we found available. I am sure we’ll learn more this week as IDF progresses so I will update this story where necessary.
What Intel calls Processor Graphics is what we used to call simply integrated graphics for the longest time. The purpose and role of processor graphics has changed drastically over the years and it is now not only responsible for 3D graphics rendering but compute, media and display capabilities of the Intel Skylake SoC (when discrete add-in graphics is not used). The architecture document used to source this story focuses on Gen9 graphics, the compute architecture utilized in the latest Skylake CPUs. The Intel HD Graphics 530 on the Core i7-6700K / Core i5-6600K is the first product released and announced using Gen9 graphics and is also the first to adopt Intel’s new 3-digit naming scheme.
This die shot of the Core i7-6700K shows the increased size and prominence of the Gen9 graphics in the overall SoC design. Containing four traditional x86 CPU cores and 1 “slice” implementation of Gen9 graphics (with three visible sub-slices we’ll describe below), this is not likely to be the highest performing iteration of the latest Intel HD Graphics technology.
Like the Intel processors before it, the Skylake design utilizes a ring bus architecture to connect the different components of the SoC. This bi-directional interconnect has a 32-byte wide data bus and connects to multiple “agents” on the CPU. Each individual CPU core is considered its own agent while the Gen9 compute architecture is considered one complete agent. The system agent bundles the DRAM memory, the display controller, PCI Express and other I/O interface that communicate with the rest of the PC. Any off-chip memory requests and transactions occur through this bus while on-chip data transfers tend to be handled differently.

By now you have read through Ryan's review of the new i7-6700 and the ASUS Z170-A as well as the related videos and testing, if not we will wait for you to flog yourself in punishment and finish reading the source material. Now that you are ready, take a look at what some of the other sites thought about the new Skylake chip and Sunrise Point chipset. For instance [H]ard|OCP managed to beat Ryan's best overclock, hitting 4.7GHz/3600MHz at 1.32v vCore with some toasty but acceptable CPU temperatures. The full review is worth looking for and if some of the rumours going around are true you should take H's advice, if you think you want one buy it now.
"Today we finally get to share with you our Intel Skylake experiences. As we like to, we are going to focus on Instructions Per Clock / IPC and overclocking this new CPU architecture. We hope to give our readers a definitive answer to whether or not it is time to make the jump to a new desktop PC platform."

The Intel Skylake architecture has been on our radar for quite a long time as Intel's next big step in CPU design. Through leaks and some official information discussed by Intel over the past few months, we know at least a handful of details: DDR4 memory support, 14nm process technology, modest IPC gains and impressive GPU improvements. But the details have remained a mystery on how the "tock" of Skylake on the 14nm process technology will differ from Broadwell and Haswell.
Interestingly, due to some shifts in how Intel is releasing Skylake, we are going to be doing a review today with very little information on the Skylake architecture and design (at least officially). While we are very used to the company releasing new information at the Intel Developer Forum along with the launch of a new product, Intel has instead decided to time the release of the first Skylake products with Gamescom in Cologne, Germany. Parts will go on sale today (August 5th) and we are reviewing a new Intel processor without the background knowledge and details that will be needed to really explain any of the changes or differences in performance that we see. It's an odd move honestly, but it has some great repercussions for the enthusiasts that read PC Perspective: Skylake will launch first as an enthusiast-class product for gamers and DIY builders.
For many of you this won't change anything. If you are curious about the performance of the new Core i7-6700K, power consumption, clock for clock IPC improvements and anything else that is measurable, then you'll get exactly what you want from today's article. If you are a gear-head that is looking for more granular details on how the inner-workings of Skylake function, you'll have to wait a couple of weeks longer - Intel plans to release that information on August 18th during IDF.
So what does the addition of DDR4 memory, full range base clock manipulation and a 4.0 GHz base clock on a brand new 14nm architecture mean for users of current Intel or AMD platforms? Also, is it FINALLY time for users of the Core i7-2600K or older systems to push that upgrade button? (Let's hope so!)
