Intel has announced a new lineup of the processor; Intel 8th Gen Core i7, i5, i3 ‘Coffee Lake’ processor for desktops. All the six announced processors are based on Intel’s ’14nm++’ Coffee Lake architecture.
Intel 8th Gen Core i7, i5, i3 ‘Coffee Lake’ CPU
The new high-end Core i7-8700K and Core i7-8700 feature six cores and twelve threads, while the new Core i5-8600K and Core i5-8400 also have six cores but without Hyper-Threading and the Core i3-8350K and Core i3-8100 have four physical cores again without Hyper-Threading.
The Core i7-8700K has base and boost speeds of 3.7GHz and 4.7GHz respectively, and the Core i7-8700 runs at 3.2Ghz to 4.6Ghz. The Core i5-8600K runs at 3.6Ghz to 4.3GHz, while the Core i5-8400 runs at 2.8GHz to 4GHz. The Core i3 models do not support Turbo Boost clock speed scaling, so the Core i3-8350K runs at a constant 4GHz while the Core i3-8100 runs at 3.6GHz.
Inside Coffee Lake Processors
The Intel Core i7 models have 12MB of cache, while Core i5 models have 9MB and Core i3 models have 6MB. Core i7 and i5 CPUs now support up to dual-channel DDR4-2666 RAM while Core i3 ones are limited to dual-channel DDR4-2400.
Intel rule out the top-end Core i7-8700K as its “best ever” gaming CPU, although this overlap the previous-generation high-end Core X-Series parts like Corei7-7740X, Intel says that its X-series chips are still better for “megatasking” applications such as encoding video and playing games simultaneously.
The Intel 8th Gen Core i7, i5, i3 have the same number of pins as 6th and 7th Gen models but will need new motherboards and a new platform controller. The company has announced only one model, the Z370, which supports up to DDR4-2666 RAM when paired with a Core i7 CPU.
So, all the major motherboard vendors including ASUS, Gigabyte, MSI, and ASRock are expected to announce a refreshed version of their Z270 motherboards to support these new processors.
Details and specification of all the six newly announced processors are already available for pre-orders. It will go on sale on October 5, but branded desktop PCs featuring these processors will come down this year.
