It’s Intel that debuts it latest, more powerful CPU architecture with integrated graphics and chipset support. Released Core i7-6700K and Core i5-6600K processrs, which of course is based on new architecture. Called Skylake, Intel’s forst new desktop CPU arrived in two years. Pre-orders are open, and interested ones can check the complete details just after this jump.
Intel has launched new high-end desktop Broadwell chips months ago and it’s been more than two years since Intel debuted a new desktop architecture, and over a year since the company’s Haswell refresh, the Core i7-4790K, launched as high-end enthusiast chipset. Today’s new Core i5-6600K and Core i7-6700K are specifically meant to replace old CPUs, with new integrated graphics, new chioset support, and all-new core architecture.
Full details on that new core architecture will have to wait until IDF August 18th, while Intel isn’t sharing much in-depth detail on the chips today. For now, we here have the initial results and discuss the platform and its positioning within Intel’s lineup.
The two new Skylake chips are the vangaurd of a full suite of sixth-generation processors coming later this year, while the entire strategy around Skylake has been a little strange, though, as we assume this would have an impact on Skylake’s launch shedule as well. Intel opted to replace the older Haswell desktop parts rather than do a top-to-bottom refresh based on Broadwell. Skylake is the follow-up to Broadwell, which makes it a “tock” in Intel’s nomenclature.
The new chip is also built on 14nm, but unlike Haswell, it uses a new socket, LGA1151. Along with a new core and socket comes a new motherboard chipset, the Z170. As initial leaks suggested, the new Z170 chipset makes a number of modest improvements to Intel’s previous high-end Z97. GPU PCIe 3.0 connectivity is the same, but the total number of USB 3.0 ports has increased to 10, up from 6. Total USB 3.0 ports is still 14, though this would seem to address the needs of all but the most crazed 3.0 version USB ports, users in general. Major chipset change you find is the use of DMI 3.0, up from 2.0. This tly means that available point-to-point bandwidth has leapt from 20Gbits/s (PCIe 2.0, essentially) up to 8GT/s (or 8GB/s), which is a huge jump, and it’s how the Intel chipset can feed the 20 lanes of PCIe 3.0 connectivity that the Z170 offers.
Theoretical advantage is the support of high-end DDR4, up to and including DDR4-4133, latency is sufficiently high compared with DDR3 that the gains are going to be modest and the higest-end DDR4 on the market, DDR4-3400, is timed at 16-18-18-36. High-quality DDR3-2133, in contrast, is timed at 8-10-10-27. DDR4-3400 is clocked 1.6x higher than DDR3-2133, but its listed latency figures are also 1.6x higher.
The Core i7-6700K and Core i5-6600K – both chipset support either DDR4 or DDRL3, with peak speed up to DDR4-2133 and DDR3L-1600 officially. The Core i7-6700K has four cores and eight threads for $350, while the Core i5-6600K is a four-core, four-thread chip with a 6MB L3.
Here’s a quick hit-list of significant features for Skylake and its new chipset:
— 16 PCIe lanes on the CPU and another 20 PCIe 3.0 lanes on the chipset. The latter is a big increase from the 8 PCIe 2.0 lanes on the last several chipsets.
— A new DMI 3.0 (Direct Media Interface) link between CPU and chipset, with double the effective bandwidth (32 gigabit/s) of DMI 2.0. This increases the throughput and effectiveness of those extra chipset PCIe lanes.
— Intel claims that very fast NVMe SSDs, which operate over PCIe, will achieve full performance over the chipset lanes (thanks to the bump up to PCIe 3.0), which means they won’t have to use the valuable CPU lanes that you want dedicated to your graphics card.
These new Skylake 6700K and 6600K CPUs are built for overclocking. Their default clocks are already high at 4.0GHz and 3.5GHz, and able to overclock to a stable 4.7/4.6GHz, respectively.
