Intel Skylake: features and performance test

Intel

Intel took advantage of yesterday’s celebration of Gamescom to present the first processors Skylake platform, advancing an official launch will occur on August 18 at the Intel Developer Forum 2015 (IDF 2015), where it is expected that the giant chip reveals more details the entire platform and other marketing models that cover the entire product range, desktops, laptops, AIO and convertible 2 in 1.

The first Skylake are already available on the international channel, also Spanish. Along with them have come new motherboards that will support the platform and new DDR4 memory kits from multiple manufacturers. At the time of launch, we get the first real test of performance of specialized portals that Intel provided models for testing. One is AnandTech and as usual, has published a complete analysis of that work to try to answer the question that many users will be making it worth the leap?

Release of Skylake

These past months I’ve been wondering why they have not come before the Broadwell market for desktop PCs. The reason is the delay in the launch by the move to 14 nm which has resulted in the end the two platforms overlap. Hence the first Skylake correspond to the desktops where Broadwell missing just have a few models sold in OEM version.

On the other hand, with Broadwell (Core M and Core U) so recent launch, Intel will space the arrival of Skylake segment, will slow those for laptops and convertibles and thus it will releasing stock. By the spring of 2016 they will all be on the market. The following will jump to 10 nm with the “Cannonlake” not before 2017. Another chapter and not less because it will be a challenge. There is no hurry. Smartphones least where competition remains ARM, Intel has more than covered the market and the situation of AMD does not tighten, at least for now.

Skylake Features 

Under a microarchitecture “tock” in a “Tick-Tock” model adopted by the chipmaker since 2007, the entire platform is made of 14-nanometer process technology using the second generation of Tri-gate transistors (FinFET).

They are including CPU, GPU and memory controller (double on some models) in the same package. The platform features new socket LGA-1151 (compatible with previous micros) 100 chipset series and new versions B150, H110, Q150, Q170, Z150 and Z170, offering support for new technologies and standards, such as DDR4, USB 3.1, PCIe 4.0 and SATA Express.

Also important (for mobile chips that are subsequently marketed) are Skylake facilities to enable “wireless computer” improving support for technologies such as Wireless Docking and WiDi Pro, including among other features, support for wireless charging and integrated cellular WWAN . We’ll see in future articles.

Core i7-6700K and Core i5-6600K

As we said, they are the first two Skylake processors to reach the market. They correspond to the high end of the platform and are intended for desktop computers. The “K” brand label chip approach, explaining that the multiplier is unlocked for easy overclocking. In previous tests, uploaded to levels close to 5 GHz with air cooling and DDR4 memories in the 4 GHz environments.

Like the rest of the Broadwell include CPU, GPU and memory controller on the die. Controller that is twofold to support DDR3 and DDR4 careful though the latter because they are DDR3L modules did not use the vast majority of users and therefore can not take advantage.

The main difference between the two processors is the Core i7 Hyperthreading allowing you to process eight threads. Also its greatest frequency (4.2 to 3.9 GHz) and most third-level cache, 8 vs 6 Mbytes.

As for the GPU, marks the launch of the new Intel IGP series 9. The company has again changed its name and is now a HD 530 (GT2) for both processors while running at lower frequency in the Core i5. In the next picture you can see the specifications of both compared with Broadwell Haswell and models in similar price level:

Motherboards, drives and equipment

All major manufacturers (GIGABYTE, Biostar, ASRock, ECS, MSI, EVGA, ASUS …) presented new motherboards with socket LGA-1151 and Z170 chipset which is supporting the Skylake desktop. From what we’ve seen her go from 80 to 400 dollars and we see that prices are updated in all new technologies: DDR4, USB 3.1, Thunderbolt 3 HDMI 2.0, multigráfica SLI or Crossfire support, etc.

Re-emphasize that these Skylake necessarily need a new base with socket LGA-1151 motherboard because they are incompatible with the above.

In memories, more of the same. We knew that would be the first platform Skylake mainstream would include support new DDR4. It announced that it would support DDR3 but the reality is that this is only DDR3L, low voltage modules do not use ordinary users and are also limited in frequency. Keep that in mind because you will be added to the budget buying DDR4. 2 or 4 modules to support dual channel.

Another point. You’ll have to buy a fan / heatsink because the processors do not include retail sales. If you go to pummeling his unlocked multiplier, advisable to use a liquid cooling solution.

Performance Test

AnandTech has conducted tests on multiple grounds, beginning with the basic computer, office automation and web usage suites. 6700K score is higher but not very different from that offered by the Core i7 4790K, his “rival” direct “:

76271-630x388 76274-630x388

If a greater difference is observed in more demanding applications such as video editing or manipulation. Interestingly, the difference in performance of Skylake is much more noticeable in Windows and Linux that can see this link.

76298-630x291 76278-630x291 76284-630x291 76297-630x291

As for the graphics performance, the advantages of the IGP process 530 HD rather decrease over previous generations. In fact, one of the few desktop Broadwell, sprayed i7-5775C Core performance and this is due to the Iris Pro 6200 including GT3. Yes slightly exceeds most integrated test against Core i7 4790K in most games.

76305-630x291 76309-630x291 76304-630x291 76307-630x291

No differences between microphones when we use third dedicated graphics or low end, or middle or high. The conclusion is that always sends the graphics and processor performance provides very little:

76313-630x291 76353-630x291 76331-630x291

Is it worth the leap to Skylake?

If you’re one of the few users with desktop Broadwell clear and direct answer is no. If you have a Haswell or you use an AMD processor response is complicated depending on the focus of the team.

If we are to use the computer for basic computing and media performance (especially CPU) it is superb in any situation in single or multi-line, although not very far from a Haswell Core i7 4790K. It also serves to games at lower resolutions although the ideal would have been to include an integrated Iris Pro 6200 and includes Broadwell K. is not worth purchasing a low-end dedicated graphics if you use these processors.

Also predictable the graphics performance difference between Broadwell and dedicated solutions from the midrange. As much as these micros unlocked Intel approach to gamers, if you want to play “capable” with some level of resolution and enabled filters will have to continue investing in dedicated graphics. If all you use or purchase a dedicated here is where alternative AMD Vishera FX come with them or without integrated graphics Intel LGA 2011 and LGA-2011-3 forms, the basic models do not cost much more than a Core i7-6700K.

Speaking of prices. The Core i7-6700K and Core i5-6600K look similar to the release of their counterparts in Haswell price: 350 and $ 250 respectively. The big difference is that you’ll have to include change through the defense budget. Plate compulsory basis and also to DDR4 memories unless you can take advantage of these DDR3L that certainly not all motherboards support.

Of course, with the jump will access to the latest technologies, buses and ports have equipment available for a few years. In the coming months will hit the market other Skylake cheaper desktop processors that will surely give more play and other combinations. What do you think? Do you plan to spend these Intel Skylake?
