Ice Lake has better integrated graphics (up to twice as fast as the previous generation), but right now there are only 2-core and 4-core solutions available, for ultra low voltage (ULV) platforms.ĪMD's Ryzen 9 3950X is the new king of socket AM4, with 16-cores and 32-threads. Intel's 10nm tech seems to be competitive with TSMC's 7nm tech, but the mobile first rollout brings up continued concerns with yields. On mobile, Intel's Ice Lake 10th Gen Core processors have arrived, about three years late (according to Intel's earliest plans). We still don't know when those will arrive, though Intel has yet another two generations of 14nm parts reportedly planned for desktops: Comet Lake and Rocket Lake. Intel denied rumors that it will skip 10nm on desktop, saying it will have some "pretty cool ones" at some point. But right now, it's all mobile solutions for Intel's Ice Lake processors. What about Intel 10th Gen 'mainstream' desktop CPUs? They're coming, we think, maybe even sooner than later. But they can be good for workstation and professional tasks. The X299 CPUs generally have higher latency and lower clockspeeds than LGA1151, so for gaming use they're often slower than the mainstream CPUs and we don't generally recommend them as 'superior' gaming solutions. Note also that pricing on the 10th Gen parts has been cut roughly in half relative to the 9th gen CPUs, thanks to AMD's extremely aggressive Ryzen 3000 series. These have anywhere from 6-core to 18-core designs, though the latest 10th Gen Cascade Lake-X CPUs drop the 6-core and 8-core models and stick to Core i9 X-series names. However, with a Z-series motherboard I have been able to run every Coffee Lake CPU with DDR4-3200 memory without incident.īesides its mainstream CPUs, Intel's high-end desktop (HEDT) X299 platform uses socket LGA2066 and supports a different set of Core i7 and Core i9 processors. Officially, the i5/i7/i9 also support up to DDR4-2666 while the Core i3 stops at DDR4-2400. The Core i5/i7/i9 parts can support up to 128GB of DDR4 (4x32GB), while the Core i3 CPUs support up to 64GB (4x16GB or 2x32GB). The CPU interfaces with the chipset (aka PCH, or Platform Controller Hub) via a DMI 3.0 interface that's basically the equivalent of an x4 PCIe Gen3 connection, with up to 4GB/s of bandwidth in each direction. Deciding which configurations to support is up to the motherboard manufacturer. Intel's desktop 8th and 9th Gen CPUs come with 16 PCIe lanes, which can interface with either a single x16 slot, two x8 slots, or an x8 slot and two x4 slots. If you don't care about overclocking, the H370 chipset is fine, though again don't pay extra for enthusiast memory as you won't be able to use its full potential. Only the Z390 and Z370 support overclocking, including running system RAM at higher than spec clocks, so we largely recommend the Z-series boards. Intel's current 300-series chipsets consist (in terms of decreasing features) of the Z390, Z370, H370, B360, B365, Q370, and H310. The 8th and 9th Gen CPUs work in the same boards (though not all boards can support the i9-9900K), but I don't expect Intel's future 10th Gen (or whatever comes next) CPUs to run in today's motherboards. Intel typically only supports one or two generations of CPU on its motherboards, sockets, and chipsets. LGA1151: 1,151 pins on the motherboard socket.
