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.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. 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.
While that might seem like a huge range, many enthusiast motherboards will run the 8th and 9th Gen CPUs at speeds much closer to the maximum turbo clock-so the i9-9900K for example typically runs at 4.7-5.0GHz in my test PC. The major desktop CPUs from Intel right now include the Core i9-9900K / i9-9900KS, Core i7-9700K, Core i5-9600K, and Core i3-8100.Ĭlockspeed for Intel CPUs can vary quite a bit, with base clocks as low as 3.6GHz and turbo clocks as high as 5.0GHz. Intel also disables Hyper-Threading support (two threads per core) on many of its processors.
Intel's CPUs tend to be bespoke designs, adding cores in pairs with 4MB or 3MB 元 cache per pair (1MB can be disabled). That's not to be confused with LGA1151 motherboards with 100-series or 200-series chipsets, as those are for 6th and 7th Gen Intel processors. All the 8th and 9th Gen desktop CPUs run in socket LGA1151 motherboards with 300-series chipsets. The first 8th Gen parts came out in late 2017, while the first 9th Gen CPUs arrived one year later in October 2018. The fastest gaming CPUs right now are Intel's latest (8th and 9th) generation CPUs, codenamed Coffee Lake. Intel's top-of-the-line Core i9-9900K, in a Z390 motherboard.
