Possible Intel 8-core LGA115x Processor Surfaces on SANDRA Database

[btarunr]

That Intel bringing 8 cores to the mainstream-desktop (MSDT) platform is more than a rumor now, as a curious-looking SiSoft SANDRA database entry suggests. An anonymous source submitted benchmark results of a processor with 8 cores, 16 threads, 256 KB of L2 cache per core, and 16 MB of L3 cache; clocked at 2.60 GHz (prototypes and engineering-samples are usually clocked low). This can't be i7-5960X or the i7-6900K, because the HEDT chips pack 20 MB of L3 cache. The more recent i7-7820X packs 11 MB of L3 cache, with 1 MB per core of L2 cache. It's conceivable that an MSDT chip could retain the cache hierarchy of the current MSDT processors from Intel, with 2 MB L3 cache slices per core, adding up to 12 MB on the i7-8700, for example, explaining the large 16 MB L3 cache on this chip.

The SANDRA numbers suggest similar IPC to the "Coffee Lake" architecture, while a proportionate increase in performance to the increased core-count. The chip scored 96 points with 237.03 GOPS score; 330.64 GIPS Dhrystone integer, 194.46 GFLOPS Whetstone single-precision floating-point; and 148.47 GFLOPS Whetstone double-precision; and 91.45 GOPS/GHz clocks/performance. Intel is rumored to launch an 8-core/16-thread LGA115x processor, possibly paired with its upcoming Z390 Express chipset, and possibly based on its new 10 nm silicon fabrication process; sometime either in 2H-2018 or Q1-2019.

8 cores on 10 nm? I thought that node was supposed to have terrible yields.

Expect 14 nm and ridiculous temperatures without de-lidding.

Where did you see 10nm? This is probably (still) 14nm, besides 10nm would imply ICL.

I saw that in this news article.

The IPC similar to CFL suggests that it's an 8 core variant of CFL, or whiskeylake, also 10nm yields are terrible. So unless there's been some dramatic improvement in that & ICL (with spectre & meltdown hardwired patches) is only as fast as CFL, I'm guesstimating it can't be 10nm just yet.

Hmm these are run on Kaby Lake S client platform. So Z370 chipsets might support these 8 core cpus after all. There are results for 6 core coffee lake with Cannon lake Client platform, which would be Z390(Well or any other cnl s; h310, b360, H370, Q370).

Edit. hmm that was mobile platform. There's CoffeeLake client platform with CannonLake client system with should be CNL S chipsets.

I need that 8 cores omg give it to me now pls

Bad yields can mean a lot of different things. Intel are able to produce good chips on 10 nm, but the amount of good chips are low, so it's a matter of cost.

Intel already make i7-7820X with 8 cores. I don't know the thermal limits of this socket, but it can certainly can consume less power than i7-7820 with a simple memory controller, less cache, no QPI and more basic core infrastructure, and no AVX-512.

IPC (Instructions Per Clock) will remain unchanged until Ice Lake arrives.

What do you guys think the odds are this chip will work in Z370 mobo's with a BIOS update? My guess is high since it most likely is just 8 core CFL.

Oh? you are expecting a IPC increase ? xD yeah maybe in 10 years.

Skylake arch @ 14nm+++ (aka 5th gen release using 14nm)

No AVX512

= Meh

 

[WikiFM]

If it will be released this year it will be 14nm Whiskey Lake, 10nm is not ready yet for mass production, if it will be released in 10nm definitely next year.
