GT3 is a 2-slice configuration, doubling GT2. So Ice Lake GT3 is up to 128 EUs or 1024 cores. I do not see it happening without HBM.

IEDM 2018: Intel’s 10nm Standard Cell Library and Power Delivery

Intel has 3 main libraries for 10nm.

HD
HP
UHP




UHP appears to be what is going to be used for desktop processors, according to Intel this library aims for 5GHz+ frequencies.

“Article” said:
On the other end of the spectrum are Intel’s ultra-high performance CPU designs which sacrifice power/area for very high performance. Those 10nm cells target frequencies greater than 5 GHz under 100% usage conditions.

First time I have read a standard library piece.

Are all current Intel Core processors on UHP? Or just desktop, and mobile on HP?

What about HMC? Is that completely MiA?
It has been abandon for GDDRx/HBMx by Micron.
"Micron announced a change in its strategy for high-performance memory solutions, moving away from Hybrid Memory Cube (HMC) and focusing on the next-generation of high-performance compute and networking solutions.

We continue to leverage our successful Graphics memory product line (GDDR) beyond the traditional graphics market and for extreme performance applications, Micron is investing in HBM (High-Bandwidth Memory) development programs which we recently made public."
- https://www.micron.com/about/blog/2...t-in-high-performance-memory-roadmap-strategy

So, the only two options are JEDEC's HBM and Tezzaron's/GlobalFoundries'(Singapore) DiRAM4.

@NostaSeronx, you've grossly misinterpreted that blog post. All Micron announced is they're working on a next-gen product, that's it. They're still implementing HMC, and Micron has called their HMC efforts successful. From the linked article:

The success of HMC is apparent by the wide adoption across a variety of technology industries. This includes:


  • futuristic applications in data science as exemplified by the Square Kilometer Array (SKA) program,
  • unparalleled high-performance compute (HPC) solutions from companies such as Fujitsu(PRIMEHPC FX100),
  • delivering 400G and beyond in high-performance network routers and data center switches, such as Juniper and other networking customers.

HMC enablement required developing a supportive ecosystem, where academia such as the University of Heidelberg created the openHMC IP, enabling FPGA-based designs to become a reality. Collaboration of Industry leaders co-developed multiple specifications of HMC through the open Hybrid Memory Cube Consortium (HMCC). The value of this teamwork and engagement should continue to harness the creativity to deliver new technology to solve future market requirements.


Now, as the volume projects that drove HMC success begin to reach maturity, at Micron we are now turning our attention to the needs of the next generation of high-performance compute and networking solutions. We continue to leverage our successful Graphics memory product line (GDDR) beyond the traditional graphics market and for extreme performance applications, Micron is investing in HBM (High-Bandwidth Memory) development programs which we recently made public.

So while they are working on HBM implementation, HMC is still on the table. A more recent post from Micron:

https://www.micron.com/insight/2018...lping-cern-unlock-the-secrets-of-the-universe

That’s where the Micron SB-852 board comes in. The board, powered by 512GB of top-of-the-line DDR4 DRAM and 2GB of Hybrid Memory Cube, is being tested as a means to further machine-learning capabilities at one of the four main LHC experiments, CMS. Micron’s memory solutions that combine neural network capabilities will be tested in the data-acquisition systems of the experiment Scientists working at CERN are looking to deploy leading-edge technologies that can support their experiments’ computing and data processing requirements. Memory plays a vital role by processing vast amounts of data, helping researchers gain valuable insights from data generated by the experiments.

HMC is very much still on the table. Intel is free to implement it if they so choose, and Micron will be more than happy to sell them the product.

It's interesting that Intel is very specifically saying 15W for Icelake: https://www.anandtech.com/show/13775/ces-2019-intel-consumer-10nm-is-coming-with-ice-lake Not "7-15W", just 15W. I wonder if Lakefield will entirely take the low power end of the market, and we won't see a Y-series Icelake?


If there was any doubt, here we have a final confirmation for the GT2 having 64 EUs onboard. Also we got confirmation that Icelake is the first 10nm volume product (and not Lakefield).

There's 64 EUs in there, just how common will fully enabled be though. Like I expect the Lakefield product to have 48 enabled, just by the Sandra samples.

I think the low single core scores indicate it was running at 1.4ghz.

Not sure where 1.9 came from?

Here's a simple shortcut to find new IceLake results (granted its L1 data cache remains the same). We've got two so far (the other two are invalid/fake).

Edit: fixed the link

how do these results compare to current chips at iso clocks? I'm not familiar with how to navigate the geekbench site.

The newer Icelake entry seems abnormally slow in some ST tests compared to the older (Ubuntu) entry: https://browser.geekbench.com/v4/cpu/compare/11585297?baseline=10445533

Almost twice as fast in some tests with only 15-35% higher clocks speeds. Linux runs faster in Geekbench but not that much faster.

The SGEMM Gflops measurement looks about right based on the clock speed difference 66.7 vs 79.4= +19%.

Yeah I arrive at +19% too. the ~10% higher score for the Ubuntu system is in line with Linux vs Windows.

That's really good, upgradeworthy if they can hit the same clocks.
