It looks like ASUS made a little bit of a mistake as they listed an Intel Core i9 10000 X-Series HEDT processor on their specifications page for the Prime X299 Edition 30. Intel has been talking about the Core i9 10000 X-Series since Computex, but this is the first listing we’ve seen of it.
The listing is interesting as it shows the chip as being a 48-lane PCIe 3.0 CPU. The current Core i9-9980XE flagship processor has 44 PCIe 3.0 lanes, so that is four more than that chip. It looks like Intel has added these extra lanes for full support of dual full speed PCIe gen 3 x 4 M.2 support.
Intel’s 10000 series is based on Cascade Lake-X, which is a derivative of Skylake-X at the 14 nm node. Chips will be up to 18-cores. Intel will also bump up default memory frequency to DDR4-2933. No word yet on when these chips will be available.
