It looks like Intel is pushing forward their X299 Chipset release with alongside it Core X processors. The announcement would be May 30th with availability June 26th opposed to a release in August.
The X299 chipset will be compatible with Skylake-X and Kaby Lake-X Intel Core X series processors. Skylake-X and Kaby Lake-X, will include 12, 10, 8, 6 and 4 core products. That 12-core version is a new one and seems to be a bit of a panic reaction from Intel towards AMD who might be releasing 12 and 16 core parts.
| Kaby Lake | Broadwell-E | Kaby Lake-X | Skylake-X | |
|---|---|---|---|---|
| CPU cores | 4 | 6, 8, 10 | 4 | 6, 8, 10, 12 |
| Cache | 8MB | Up to 25MB | 8MB | 13.75MB |
| PCIe support | PCIe 3.0 (16 lanes) | PCIe 3.0 (40/28 lanes) | PCIe 3.0 (16 lanes) | PCIe 3.0 (44/28 lanes) |
| Integrated graphics | Yes | No | No | No |
| TDP | 95W | 140W | 112W | 140W |
| Socket | LGA 1151 | LGA 2011-v3 | LGA 2066 | LGA 2066 |
| Chipset | KBL PCH-H | X99 | KBL PCH-X | KBL PCH-X |
| Memory support | Dual-channel DDR4 | Quad-channel DDR4 | Dual-channel DDR4 | Quad-channel DDR4 |
The X299 will bring quad-channel DDR4 support to compatible 14nm processors and 40 PCIe 3.0 lanes with Skylake-X procs. Kaby Lake-X procs will support dual-channel DDR4 and 24 PCIe 3.0 Lanes. Before you ask, why release both Skylake-X and Kaby Lake-X at the same time and what is the difference? Well, Skylake-X thus can offer 12, 10, 8 and 6 core processors, the other (Kaby lake-X) remains to be a quad-core part. Skylake-X are the extreme edition like the 6950X series currently on Skylake-X. These processors will get a 140 Watt TDP, the quad-core Kaby Lake-X is rumored to be a 112 Watt part.
Since the processors once again will need a new socket, LGA 2066t hat means that once again you have to purchase a new motherboard. There is a rumor right now that Intel is tweaking the cache sizes to increase performance. The new platform thus also offers support for Intel Optane and quad channel DDR4-2667 MHz memory.
