Lenovo released a Cannon Lake laptop

[not_someone]

https://item.jd.com/26395831443.html is the one, Core i3-8121U with single channel memory and a Radeon 540 dGPU, no iGPU.

The base clock is 2.2 GHz, with 3.1 GHz single core turbo (https://twitter.com/jfpoole/status/987424310393430016?s=19) and around 2.6 GHz multicore boost on Cinebench (https://twitter.com/Dayman58/status/995290335910727681).

Looks like it's VERY disappointing for a 15W part, AVX2/512 clocks would be only even more nightmarish.

Is this real? You can actually buy one?

Yes.

It's the effect everybody was already talking about: Intel successfully kept pushing 14nm into such high frequencies that they now have troubles achieving the same for 10nm, making it look like a step backward and ensuring that it will be further and further delayed.

Think it's more about binning as loose as possible to ensure that any chips with both cores actually functional are usable.

Essentially the same difference. Regardless of cause so far Intel has no 10nm product that would look well among their 14nm products. Intel kept pushing (and exploiting) the maturity of 14nm, so the lack of it for 10nm is an obvious disadvantage.

And the iGPU is entirely non-functional. What a mess. This product is definitely a "CEO bonus special", no other explanation for actually shipping this turd.

You know it's bad when Intel aren't even marketing it.

The embarrassing thing is Intel designed CNL-U as dualcore CPU and thought this is good enough. It's a big design failure.

Honestly, even this is overkill for the targeted market. Well, if it had a functional GPU.

 

[mikk]

I'm sure CNL-U wasn't targeted for some low end crap.

True but I imagine the focus was the 5.2 W Y though.

 

[mikk]

5W Y is a very limited market, U is much more important. And even for 5W Y 2C is a poor design choice, it's hard to advertise 2C and to be honest 2C for a 10nm product what a failure from Intel.

 

[LTC8K6]

Haven't we known about the 8121u for a while now? I don't recall it's performance being poor in the leaks.

Serious question, what products outside of games do you use that might actually come close to utilizing 4 cores?

I think Intel intended Y to be much more popular by marketing fanless laptops. 15W you need a fan.

Dual core without even a functional igp is disaster, maybe the cpu have lower power consumption, but without igp whole package will consume more power.

Well, seems that this gets throttled to 2.6GHz with 2 cores used at 15W, so 4.5W is out of the question for this part.

You need a functioning GPU for a 5W part! Can't exactly pair it with a 15W GPU in a tablet...

Pretty sure Intel can restrict the max turbo at given cores for marketing (or binning) reasons. So if the contra-revenue rumor was about Cannonlake maybe Intel doesn't want it getting that close to the 8130U.

Plans don't always go exactly to plan, you know.

The 8130U is an much older Kaby Lake-U part. It's damning that no Cannon Lake higher-end parts even exist

And I was wondering why there are CPUID for 2+0 Parts.... turns out 10nm is possibly much worst then we thought.

Might be just an unfixable HW design defect, that they've remedied with a new stepping. Or the GPU part is very hard to fab, with resulting low yields.

I'm not hopeful though.

Intel basically confirmed that 10 nm functional yields are still in the toilet. It's not a GPU specific issue, simply that yields are that bad.

 

[FIVR]

I don't really understand what is going on with this 10nm product. What is the issue with the lack of GPU? Why can't they get the GPU to work and why is the chip as a whole using so much power to produce such a low score?


Also, it appears some of the subtests indicate better IPC, yet somehow the chip as a whole has horrendous performance... what is going on here?


It seems there is some issue with 10nm drawing insane amounts of power which to me sounds like a leakage issue.

The BEOL on Intel 10nm is just that bad.
