Anandtech forum member Sweepr recently leaked a slide of what appears to be Intel’s upcoming product stack for its LGA2066 HEDT platform and it details a lot of information on the upcoming product if true. While no official word has been released yet, the tech community has responded to the posting as credible and reported on the details as seen below.
In the leaked slides, Intel is reported extending its Core family line-up processors to include a Core i9 series. Intel so far only has used the Core i7 branding for all its high-end processors on both desktops and laptops including both mainstream and high-end desktop (HEDT) platforms. The new LGA2066 socket will see two product microarchitecture at launch with the Core i7 quad-core processors carrying the Kaby Lake-X design while the higher-end Core i9 will carry the Skylake-X microarchitecture and will have 6-core, 8-core, 10-core and 12-core SKUs.
The Core i7 Kaby Lake-X line-up will have the processors we previously reported mainly the i7-7740K and the i7-7640K quad-core chips. These CPUs will have 1MB of L2 cache per core, four times the size of the i7-7700K’s L2 cache. L3 cache varies for both chips with the i7-7740K having 8MB and the i7-7640K sporting 6MB. Clock speeds for the i7-7740K is pegged at a base 4.3Ghz and will have a Turbo Boost frequency of 4.5Ghz. The i7-7640K on the other hand has a base frequency of 4Ghz and will boost up to 4.2Ghz via Turbo Boost and will not have HyperThreading which the i7-7740K processor has.
Moving over to the Core i9 stack, the series will have 4 SKUs under its brand namely the Core i9-7800X six-core, i9-7820X eight-core, i9-7900X ten-core and the flagship Core i9-7920X sporting 12-cores. All the Core i9 SKUs will feature HyperThreading and 1MB of L2 cache per core. Further details are as follows:
- Core i9-7920X
12C/24T
16.5MB L3
44 PCIe lanes
Clocks TBD (August Launch)
- Core i9-7900X
10C/20T
13.75MB L3
44 PCIe Lanes
3.3Ghz Base
4.3Ghz Turbo 2.0
4.5Ghz Turbo 3.0
- Core i9-7820X
8C/16T
11MB L3
28 PCIe Lanes
3.6Ghz Base
4.3Ghz Turbo 2.0
4.5Ghz Turbo 3.0
- Core i9-7800X
6C/12T
8.25MB L3
28 PCIe Lanes
3.5Ghz Base
4.0Ghz Turbo 2.0
The Core i9-7800X, i9-7820K, i7-7740K and i7-7640K will have 28 PCIe Gen3 lanes sufficient for 2-card multi-GPU setups at x8 per card while the i9-7900X and i9-7920X will have 44 lanes which allow 3-4 multi-GPU setups. The Kaby Lake-X SKUs will also be utilizing only dual-channel DDR4 configurations while the entire Core i9 line-up will have access to a phat quad-channel DDR4 interface. The LGA2066 socket will natively support quad-channel wiring but will only function at dual-channel when a Kaby Lake-X CPU is installed.
The new CPUs are expected to launch in split releases with the first wave arriving this June 2017 and the high-end Core i9-7920X following at August 2017.
