Intel Sunny Cove(Ice Lake and Comet Lake) examined in more detail

[CAT-THE-FIFTH]

A great write-up by Anandtech on the new Intel core design being launched with Sunny Cove in laptops:

It looks like the next generation 10000 series Intel mobile CPUs will be a mixture of 4C 10NM Sunny Cove based Ice Lake CPUs, and 6C/8C 14NM Skylake based Comet Lake CPUs.

Very good for the laptop market and it's gonna be interesting to see what this new architecture is capable of. I suspect their "up to 4.1 GHz" claim might be taking a leaf out of AMD's book, i.e. we won't actually see any chips that hit that speed for more than a second. I notice they're officially supporting DDR4 @ 3200 MT/s too, something they've never done with their Skylake derivatives.

Was the last time Iris Pro graphics were seen in Broadwell-C?

Intel claims an ~18% IPC improvement, which means that their "up to 3.9 GHz" @ 15 W Ice Lake-U parts wouldn't quite match their "up to 4.9 GHz" @ 15 W Comet Lake-U parts, unless of course they have better sustained frequencies relative to the 14nm parts. They're also stuck on 4 cores whereas Comet Lake-U will probably have up to 6. The 9 W versions and improved graphics look tasty though.

Doesn't bother me since I don't have a laptop.

But these 10nm chips are still exciting for low power laptop users.

You can have a ultra thin or high battery life unit while still maitaining great performance.

Even though it's 4c/8t - at 3.8/3.9ghz and just using the Geekbench results we've seen - they are on par with a gaming 5ghz i9 laptop in single thread

They used 3733MHZ DDR4 and the Coffee Lake systems used 3200MHZ DDR4,but it is unclear if the RAM was run at that speed or 2133MHZ.

However,the model tested was $426:

This is for a 4C/8T model - it appears anything over 6C for mobile is still based on Coffee Lake.

Its lucky for AMD Intel is still stuck at 14NM for desktop,and Ice Lake is still only a 4C/8T CPU.

Well they may be stuck at 4c for 10nm, but st least they got their 20% ipc boost

It gives an indication of what intel might have at the end of next year or early 2021 on desktop.

AMD needs to make sure they keep up the improvements with their CPUs.

 

[hominid]

they got their 20% ipc boost

They've also lost ~20% in clock speed, so I expect them to be about the same speed on the CPU side - GPU will be faster but then it needs to be!

They've also lost ~20% in clock speed,

dont be daft, the reason for lower clocks is the tdp limit. on desktop where they can pull 80+w of power wont be surprised if base clock is 5ghz.

If they could get anywhere near that they'd be releasing them on desktop, there's only one sku with a base clock higher than 1.3ghz

Unless they call the maximum boost clock of a single core "base clock", this new 5 GHz "base clock" is technically impossible.

My Ryzen 5 2500U has a documented "base clock" of 2 GHz, but most of the time sits at 1.47-1.50 GHz, with boosts to 3.00 GHz, and very rarely maximum turbo clocks for 1 core of 3.60 GHz.

SPEC2017 is another one of those benchmarking tools that claims its a measure for real world performance but uses its own code IP.

Every generation since Ivy Bridge Intel have used benchmarking tools to claim a 15% IPC increase that then turned out to be 3% in the real world.

Having said that the 1065G7 looks impressive on the face of it, its scoring 461 ST in Cinebench, that's at 3.9Ghz, yet somehow with Intel's "+18% IPC" rhetoric i was expecting more than that, i score 482 at 4.1Ghz, that's 5% higher clocked than Ice Lake with 5% higher score.

So Ice Lake matched Zen 2 IPC, and that's not "+18% IPC" its about 10%.

I also think by the time this gets to Desktop we will be talking about Ryzen 5000
