In view that it launched in early March, AMD’s Ryzen 7 and Ryzen 5 families have blown holes in Intel’s midrange and high-conclusion desktop product segments. It was only a rely of time until Chipzilla retaliated, and a leaked slide from a German presentation suggests that Intel is stepping up its personal Skylake-X HEDT (excessive conclusion computer) platforms.

In response to the leaked counsel, Intel will offer a suitable-conclusion 12-core Core i9-7920X, with 24 threads and 16.5MB of L3 cache, with 44 PCIe 3.0 lanes. Base clock and turbo frequencies are all TBD, however the chip supposedly has 16.5MB of L3 cache. The different chips are listed as follows:


Core i9-7900X: 10 cores, 20 threads, 3.3GHz base, 4.3GHz rapid, 4.5GHz turbo raise 3.0, 13.75MB of L3, 44 lanes of PCIe 3.0.

Core i9-7820X: 8 cores, 16 threads, 3.6GHz base, 4.3GHz rapid, 4.5GHz rapid boost 3.0, 11MB L3, 28 lanes of PCIe 3.0

Core i9-7800X: 6 cores, 12 threads, 3.5GHz base, 4GHz faster, no turbo increase 3.0, 8.25MB L3, 28 lanes of PCIe 3.0.

Core i7-7740K: 4 cores, 8 threads, 4.3GHz base, 4.5GHz turbo, no faster increase 3.0, 8MB L3, 16 lanes of PCIe 3.0.

Core i7-7640K: 4 cores, 4 threads, 4GHz base, 4.2GHz rapid, no faster raise 3.0, 6MB of L3 cache, 16 lanes of PCIe 3.0.

The two Core i7 chips can be Kaby Lake-derived while the relaxation of the Core i9 household is according to Skylake-X.
No clean in shape with current Intel products

I am not in any respect definite these leaks reflect the chips Intel will announce at Computex. First, there is the volume of L3 cache. These new cores have a ways less L3 cache than any current Intel HEDT chip — Intel’s 10-core 6950X, as an instance, has 25MB of L3. For the final six years, all of the means again to the 3960X, Intel has provided 2-2.5MB of L3 cache per CPU core in the HEDT family. These new chips decrease that ratio to 1.375MB per core.

Sweepr, the Anandtech poster who leaked this advice, claims that Intel has made up for the sharp L3 deficit through quadrupling the size of its L2 cache. Whereas we have talked earlier than about how Intel might respond to AMD’s Ryzen, there is no method Intel may have maybe made this trade in response. Increasing cache sizes without negatively impacting cache latency is a major undertaking; Intel would have had to do a primary respin on Skylake to make this change. If these cache counts are correct, they reflect plans Intel made a 12 months or greater in the past, now not any recent response to a renewed aggressive environment. And the way helpful (and how tremendous) quite a lot of caches deserve to be for most beneficial efficiency is partly a characteristic of the cache structure. Expanding the L2 cache by means of 768KB doesn’t automatically compensate for shrinking the L3 cache.

If this leaked roadmap is right–and that is a large if–it implies Intel will not be fixing one of the crucial artificial segmentation boundaries that is most irritated lovers: the lockout on PCI express lanes. in case you want to run two photographs cards at full x16, you should buy a ten-core chip to do it. Until Intel plans to notably decrease fees, that might be a worse deal than at latest. Currently, the Core i7-6850K helps forty PCI-express lanes with an MSRP of $617 – $628. Intel’s 10-core processor, the 6950X, is a $1,800 core. Unless Intel plans a serious rate cut at this core count number, fans will must pay exact dollar for a 32-lane answer. Ryzen 7 does not at present a 32-lane solution either, even though there’s speculation that the company’s rumored HEDT competitive answer will, when and if it’s released.

At last, it is not clear why Intel would even bother releasing Core i7 CPUs with these specs. There is the tiniest trace of an upgrade within the i7-7740K, with its 4.3GHz base clock as opposed to the 4.2GHz base clock of the 7700K, but the Core i7-7640K is not an i7 at all. It is nothing but an i5 with better base clocks, and any 4-core / 8-thread i7 from the past few years will outperform it in any multi-threaded application of notice. Releasing an entry-degree HEDT “Core i7” that could assuredly be outperformed by the Core i7-4790K, 6700K, or 7700K isn’t the optimum solution to encourage fanatic adoption and that I’m taking these rumors with a good little bit of salt.
