So the newest Cortex will roughly match the 2016 Apple A10 CPU? No wonder so many android tablets are painfully slow...
It may only be similarly effective, but much more efficient.

My current laptop is a cheap Dell from 2015. It contains an unimpressive Celeron N2840 @2.16GHz but it is surprisingly usable for Web and office tasks and very low power (I never hear the fan). So I think you should also benchmark it against current Celerons (N3710).
On paper, your Celeron is specified to run at 6 W max[1], and of course has 4 cores; that's 1.5 W/core. The AnandTech article says[2] that the new Cortex-A76 can run with a power budget of 750 mW/core, which is exactly half of the Celeron's, then.

Those 6w are a lie, the same way a core-m chips having 4.5 tdp, which in reality go as far as 17.5w.

You need to compare few things other than raw performance. Latest Apple chips are humongous for ARM based SoCs.
This is in big part due to them having bigger caches than some server CPUs.

#14I wanna see a realistic benchmark that compares it against intel's x86 i"X" (6th, 7th, 8th gen) to decide if it can be called a laptop class processor in first place... BTW, it's interesting to see how good apple is in designing their custom Arm processors.

Current Celerons would be Gemini Lake (https://ark.intel.com/products/codename/83915/Gemini-Lake), if not the generation after that - after all, A76 is not exactly shipping.

> it's interesting to see how good apple is in designing their custom Arm processors. ooh, probably because apple acquired a company called pa-semi (300m iirc) which had a bunch of cpu dudes doing power-efficient chips for quite a while...
Gotta go down as one of the best acquisitions, it is clearly a foothold for Apple that allows them to release products no one else can... Custom silicon chips are the basis for nearly all of their differentiating products - FaceID / Airpods / Apple Watch

#16Any idea if it would be affected by Spectre?
Re: Arm unveils 7nm Cortex-A76 CPU
#17I wonder whether attempting to move into a laptop form factor will translate to more emphasis to get these reference SoC's fully on the mainline kernel. You'd have thought it would make it a lot easier for any non-Windows products to be launched if that was in place.

so the TDP is a gross average measure ?

They vaguely claim the processor design has extra attention to mitigating out-of-order execution based attacks.
