Intel Core i3 N300 is a Core Processor with Just E-cores That Somehow Isn't an Atom or Pentium Silver

The upcoming Intel Core i3-N300 is an upcoming entry-level mobile processor that only has "Gracemont" E-cores, no P-cores, and yet somehow isn't branded under Atom or Pentium Silver. This isn't just because Intel retired the entry-level brands in favor of a generic "Intel Inside" brand to be used on entry-level notebooks; but very likely because of the way these chips are architected.

The i3-N300 and i3-N305 were spotted in separate Geekbench submissions discovered by Benchleaks. The chip is identified as having 8 cores and 8 logical processors (threads), but its cache is identified as being 4x 64 KB L1I, with 4x 32 KB L1D, 1x 2 MB L2, and 1x 6 MB L3. It's possible that the chip's design is very similar to a conventional "Alder Lake" processor—with a centralized L3 cache and client interconnect fabric, an uncore, and an iGPU; but with no P-cores, just the two "Gracemont" E-core clusters, each with 2 MB of L2 cache shared among 4 cores.
"Gracemont" lacks HyperThreading support, which makes this chip 8-core/8-thread. The chip comes with clock speeds of 1.80 GHz base, with 3.80 GHz boost. The chip scores a fairly high single-thread Geekbench number of 1025 points, but with 4420 points multi-thread. This would put the processor's performance roughly on-par with AMD "Renoir" Ryzen 4000-series mobile processors in the multi-threaded score; but its single-threaded score is quite-something, on par with a "Cezanne" Ryzen 5000-series mobile chip.

Slightly below the Ryzen 5 4500U(1100/4600) which is 6C/6T and much slower than models with active SMT, 4600U (1100/5500)

This is exactly what they teased with the release of Alder Lake. If entry-level client servers didn't see as much value in AVX we'd have seen these launch shortly after 12th gen as Celeron/Pentium. But Intel decided to keep the feature set identical from top to bottom with Alder Lake and skip making an E-core only design until later.

Looks a little more like a "Lucienne" than "Cezanne". ST bench is just over the 5700U. Also MT right around the 5500U, so "Lucienne" again.

That is 8T in a tiny cost-effective chip, targeting power constrained offerings where 1T or gamingperf is not the primary focus.

And this fuels the rumors that Gracemont is not 100% the successor of Tremont because it is not purely focused on power-efficiency but area-efficiency instead.
There are rumors, that Crestmont will follow those Gracemont targets where another offering will follow stricter power-efficiency like Tremont and Atom did.

its always nice to find more than 4 chips in as non-server atom sku - definitely something to watch out for on discount notebooks!

Interesting, like a more efficient version of my coffee lake i5?

Its TDP should be something really nice:

That thing has what 15W TDP IIRC? This chip, if it's a full fledged desktop part, almost certainly has 2x of that.
So there's that. Also 5700u can be a fair bit faster, this likely at 25W cTDP ~
ARFIts TDP should be something really nice:

So you're thinking TDP of 7.5W for these chips? Impossible with the scores you're seeing!

N300... what a refreshing name after the hundred digit Core CPU names we're used to seeing from Intel! :rolleyes:

*This* is the CPU I've been waiting for ever since Alder Lake was announced with Atom-successor E-cores with Skylake-level performance. That is still a lot of performance for most day to day tasks and 8 cores is as good as I'd expected. That multi-core score is weak because these seem to be clocking down to stay within a that tiny 7.5W threshold, but IMO paired with a modest low-powered dGPU (1650 Ti or 3050 laptop lowest power variant), this could be a *very* light all day battery laptop with decent lo-mid settings gaming capabilities.

ArcoIf its 10 watts I bet you can just put a block of metal on it and call it a day.
I have a 35 W Core i7 cooled by this. It stays around 60 °C under heavy load.

Waste of material. Better a small fan and a tiny heatsink.

Maybe with this someone could make a cheap Windows tablet that doesn't suck.

Count von SchwalbeStrictly off of the geekbench leaderboard, as that is where the scores here were from.

Single core:


Multi-core:
These numbers seem far below normal.

I prefer to rely on notebookcheck data which considers the average score of all notebook models analyzed. :P

I honestly didn't know if they were individual or average or what. I assumed they are average - I usually use Passmark anyways.

I know that there are going to be a lot of haters again but I have to say this is really, really cool. I was wondering for some time when they would release an octacore Atom (like octacore phone and tablet SoCs) and now it has finally happened. This will probably have fantastic performance per watt and there is no stupid, insecure SMT garbage. I just hope it will not only appear in trash quality laptops. We need this in NUCs and other mini PCs.
