Two new entries for the upcoming Intel Coffee Lake eight-core CPU have surfaced on our favorite leaky benchmarking database, SiSoft Sandra. There are two outcomes for the unnamed processor, operating on two totally different platforms, probably one in every of them the unreleased Z390 board.
The entries appear to point a fairly early engineering pattern, and clockspeeds range fairly wildly between the 2 entries. The first has been benchmarked on the Intel Kaby Lake shopper platform, and runs at 2.6GHz, and the second runs on the Coffee Lake platform, with the Cannon Lake shopper system, however solely at 1.7GHz.
This could appear somewhat unusual, however SiSoft and early engineering samples don’t all the time play properly collectively. It’s probably that the eight-core chip is being examined throughout each the Z370 chipset, which runs on the identical 22nm PCH because the Intel Kaby Lake technology; and the upcoming Z390 chipset, which runs on the 14nm PCH. This course of was initially deliberate for roll-out alongside 10nm Intel Cannon Lake processors.
Want the very best Intel CPU for gaming? Here are our high picks.
Despite the Kaby Lake reference, there’s just about zero likelihood that the eight-core chip shall be backwards suitable with the Z270 platform – significantly, don’t get your hopes up. With Intel’s observe document this transfer would nullify the reasoning Intel gave for the dearth of compatibility between Coffee Lake and Kaby Lake chips after they first launched in October final yr. So, even when this have been attainable (which modders appear to have confirmed considerably), it appears extremely unlikely to stay round for the completed product.
The Intel Z390 chipset, set to launch near, or alongside, the eight-core chip will utilise the 14nm course of, and supply native USB 3.1 Gen.2 assist. This will full the Coffee Lake lineup on 14nm, with solely the Z370 remaining on the 22nm course of and older chipset. Rumours recommend the Z390 motherboard could also be suitable with future Ice Lake ninth Gen Intel processors – however the place does that go away the Z370 and early adopters?
Back to the benchmarks, nonetheless. The two entries uniformly function 256KB of L2 cache per-core, and a grand complete of 16MB of L3 cache. That’s nonetheless 2MB per-core as it’s on the six-core i7 8700Ok. Apart from that, we will’t discern a lot else from the listings themselves other than the actual fact it’s a HyperThreaded octa-core with 16 threads. Naming can be a thriller. An eighth Gen Core i9 is the present favorite for the eight-core chip, nonetheless, a Eurocom consultant urged in April that Intel may launch the chip with the 9th Gen.
The Z390 chipset is anticipated to launch in Q3, 2018, with the eight-core processor anticipated quickly after – in spite of everything, it’s just about the one excuse Intel have for launching a brand new fanatic motherboard so late within the day for the Coffee Lake platform. Z390 motherboards, at the very least, might make an look at first of June for Computex.
