Intel Company intends to bring to market a new line of high-performance desktop processors by expanding the list of available episodes. Soon consumers will be available with Intel Core i9.
At the moment, series Core i7 includes performance processors for a mass segment (performed LGA115x), and for high-level systems (and with connectors LGA1366 LGA2011). It would be logical to divide the series and leave the Core i7 name for the mass segment, Core i9. But Intel decided to go another way. Along with the release of the new platform, and the new processor socket LGA2066 Company creates chips in two series: Core i7 Kaby Lake-X with four cores and Core i9 Skylake-X, which may be 6, 8, 10 and 12 of cores.
Series Core i7 Kaby Lake-X will include chips Core i7-7740K and Core i7-7640K, and the release of Core i5 Kaby Lake-X is not planned. The new processors will receive 1 MB dedicated cache memory for each second level kernel (this is 4 times larger than the current Core i7-7700K). At the same time Core i7-7740K has 8 MB of shared cache in the third level, while the Core i7-7640K – only 6 MB. Another limitation of Core i7-7640K is a lack of support for HyperThreading technology, although it has a Core i7-7740K. Finally, these models will be different of operating frequencies: for the Core i7-7640K the nominal frequency is 4.0 GHz, and mode Turbo Boost – 4,2 GHz; to Core i7-7740K – 4,3 / 4,5 GHz. A TDP is up to 112 watts.
Series Intel Core i9 Skylake-X would consist of four parts, including a 6-core Core i9-7800X, 8-core Core i9-7820X, 10-core Core i9-7900X and 12 Core i9-7920X-core processors. All devices receive support HyperThreading technology and 1MB allocated cache in the second level for each core. A TDP is up to 140 watts. Let us consider more detailed characteristics of each chip:
- 6-core Core i9-7800X – 8448 KB (8.25 MB) total L3 cache, the base frequency of 3.5 GHz, the frequency mode Turbo Boost 4,0 GHz;
- 8-core Core i9-7820X – CB 11264 (11 MB) of the total L3 cache, the base frequency of 3.6 GHz, the frequency mode Turbo Boost 4,3 GHz;
- 10-core Core i9-7900X – 14080 CB (13,75 MB) total L3 cache, the base frequency of 3.3 GHz, the frequency mode Turbo Boost 4,3 GHz;
- 12-core Core i9-7920X – 16896 KB (16.5 MB) total L3 cache, the operating frequencies are not specified.
4-core Core i7 Kaby Lake-X, as well as models of Intel Core i9-7800X and Core i9-7820X will support 28 PCI-Express 3.0 lines. Thus, users can set the configuration of SLI / CrossFire graphics cards only in x8 mode for each. At the same time, processors Core i9-7900X and Core i9-7920X officially supports 44 PCI-Express 3.0 lines that allow you to create a configuration of three or four cards.
Processors Core i7 Kaby Lake-X will receive a two-channel memory controllers, DDR4. At the same time for a series of Core i9 Skylake-X provides four-channel memory controllers. Motherboard with LGA2066 processor socket will initially support quad-channel memory configuration and up to eight DIMM slots. But when installing processors Core i7 Kaby Lake-X two memory channels are inactive.
According to available information, the new processors Core i7 Kaby Lake-X and most of the chips Intel Core i9 Skylake-X will be presented in June 2017. A top 12-core processor Intel Core i9-7920X debut in August of this year.
