Skylake-X And Kaby Lake-X Thread
#1
https://www.techpowerup.com/232272/intel...f-schedule
Quote:The rumor mill turns, and Ages come and pass, leaving memories that become legend. However, some of those really do turn to reality, like recent accounts of an AMD Polaris 20 chip surfacing in the latest RX 500 series. This time, Intel is in the crosshairs, with the company's high-performance Skylake-X and Kaby Lake-X desktop components being pegged for release between June 19th and July 9th. This would place an announcement on the new chipset and CPUs debut to drop around Computex 2017, which kicks off on May 30 and runs through June 3 in Taipei.

Skylake-X and Kaby Lake-X parts are supposed to use the same LGA 2066 socket, with Skylake-X said to include anywhere between six to 10 cores, support quad-channel DDR4 memory and have a metric ton of PCIe 3.0 lanes. Kaby Lake-X parts, meanwhile, are reportedly limited to just four cores, dual-channel memory and just 16 PCIe lanes from the CPU - which gives an impression of a simple, Kaby Lake desktop CPUs being repackaged for the new socket.

Quote:Leaks came from the SiSoft Sandra Benchmark, again, which shows the Intel Core i7-7740K running on a Gigabyte X299 Gaming 3 motherboard at 4.2GHz base and 4.5GHz Turbo clocks. The X-series family of processors is expected to have a wide range of various core-configurations from 4, 6, 8, 10 and 12-core processors, on the new X299 platform. At the same time, Intel will also have a Skylake-X CPU, expected to be for the top-end 12-core/24-thread line with 44 lanes of PCIe Gen 3.

Quote:There's a lot to talk about here. Most profound is further fuel for the notion that Intel will once again be increasing the core count of its top-shelf Core-series processor, this time to 12 cores. The idea of having to buy a ten-core processor to run a pair of graphics cards with a full 16 lanes of PCIe 3.0 for each remains as annoying as ever.

A few discrepancies popped up between the information posted by Sweepr and the information in the image posted by dooon. Sweepr claims that the Skylake-X-based Core i9 processors will have TDP specs ranging up to 160W, but all of the chips in the image appear to say 140W. Sweepr also claims that the Skylake-X processors will have 1 MB of L2 cache. That would be four times as much as today's Skylake and Kaby Lake processors, and might help to explain the relatively paltry amount of L3 cache in the Skylake-X CPUs. The Core i7-6950X ten-core CPU has 25MB of L3 cache, for comparison's sake.

The information didn't come with any pricing details, so we'll have to wait and see what the bottom line looks like for these chips—assuming this information is even accurate. If so, that means we'll be seeing these parts next month save for the 12-core Core i9-7920X. That part is supposedly launching in August.

Quote:These should be two of the top performing processors in Intel's line-up, and the i9 7900X (10-core) and 7920X (12-core) have been tested on integer and floating point calculations. The 10-core i9-7900X (3.1 GHz base frequency, no Turbo listed)) scores 107 points in single-core benchmarks, and 1467 points in the multi-core test. The 12-core, 2.9 GHz base frequency 7920X, however, scores a head-scratchingly-higher 130 points in the same single-threaded benchmark, despite carrying the same architecture at... hmm... lower clocks. Maybe this processor's Turbo is working as expected, up to 3.25 GHz (average), and that's the factor for the higher single-core performance?

The fact that these scores were sourced from userbenchmark.com means that there isn't much reason to compare them between processors - it's an environment lacking the usual control usually found in reviews - so that may also be the reason for the discrepancy. Multi-threaded performance is more inline with what we'd expect to see, though, coming in at 1760 points. You should also note that the Core i9-7900X shows a base clock of 3.1 GHz, 0.2 GHz short of its official 3.3 GHz specification, which means we're probably not looking at final silicon. As always, and this should go without saying, take leaked benchmarks with some amount of salt (a pinch or a truckload, your mileage may vary.)

Quote:A new, leaked slide on Intel's X-series processors shows 18, 16, 14, and 12-core configurations as being available on the upcoming X299 platform, leveraging Intel's turbo Boost Max Technology 3.0 (which is apparently only available on Intel's Core i9-7820X, 7900X, 7920X (which we know to be a 12-core part), 7940X (probably the 14-core), 7960X (16-core) and the punchline 7980XE 18-core processor, which should see a price as eye-watering as that name tumbles around on the tip of the tongue. There is also mention of a "Rebalanced Intel Smart Cache hierarchy".
