Intel 12th Gen Alder Lake CPU benchmarks, specs, and prices reportedly leaked online

Written by Stuart Thomas on Fri, Sep 10, 2021 4:44 PM

Intel is making one hell of a comeback after their disappointing launch of the Intel 11th Gen Rocket Lake processors earlier this year. Not only does the Blue Team have their first proper desktop graphics cards launching next year in Q1 2022, but they’re also launching some innovative new CPUs at the end of this year.

The 12th Gen Alder Lake CPU lineup is set to shake things up in the world of desktop processors thanks to its hybrid architecture design. Unfortunately, all we know about them is that they are launching by the end of the year. But a new leak has supposedly revealed the benchmark performance, specs, and prices of some of the new lineup.

This includes the flagship Core i9-12900K, Core i7-12700K, and the Core i5-12600K. Obviously take all this information with a grain or two of salt, but as is usual with tech leaks like these it comes from a foreign outlet that tends to sneak past the embargo details or manages to get hands on with early samples before launch. So some specs/prices/performance may vary at release.

No details have been provided regarding the setup or any details surrounding the benchmarks (like whether it was using Windows 11, which Alder Lake should get better performance out of), so again take these results lightly. However, if they are even remotely true, then they can give us a decent indication of how the new CPUs will perform when they launch.

Now let’s get onto the juicy stuff, what we’ve all come here for. Before we jump into the benchmarks, let’s take a look at the alleged Intel 12th gen Alder Lake specs and pricing…

Intel 12th gen Alder Lake CPU benchmark

The following results were conducted using the Geekbench 5 benchmark tool for both single core and multi-core performance numbers, comparing the upcoming Intel 12th gen Alder Lake processors with some other Intel and AMD CPUs. The higher the number, the better the performance.

Intel 12th gen Alder Lake CPU single core performance


Intel 12th gen Alder Lake CPU multi-core performance


As you can see in the above results, the Alder Lake lineup completely outpaces the other CPUs in Single core performance, and is roughly on par with some of the best AMD processors in multi-core performance, which is all quite impressive for the new hybrid architecture.

For instance, in multi-core performance the Core i9-12900K is supposedly at the same performance level as the Ryzen 9 5950X, and both the Core i7-12700KF and Core i5-12600KF are apparently faster than the Ryzen 9 5900X and Ryzen 7 5800X respectively.

If these performance numbers are true, then the Alder Lake pricing is a very good deal considering their AMD Ryzen 5000 counterparts are priced around $200 higher. We’ll have to wait and see if Intel officially confirms the specs and prices soon, but with a supposed launch in November we should hopefully get some concrete info sooner rather than later.

What do you think? Are you excited for Intel 12th gen Alder Lake CPUs? What do you think of the performance? And how do you feel about the specs and pricing? Let us know!

I'm reserving my judgement until these are released and they have been reviewed by everyone with Windows 11.

But if this is true, then its promising. Just gotta keep in mind how power hungry the i9s are.

01:40 Sep-11-2021

That does actually look pretty promising if true.

Thing is, I literally just ordered a 5900X + mobo + cooler + case + a new 4tb ssd for about 1600€ 😐️

Provided leak is actually true, most of it doesn't look bad at all. But it is bit weird that locked i5 won't have efficiency cores... like for those I would expect to either have them or be cheaper. Or at least to make it differentiating factor between 12600 non-K and 12400. Since mostly it is just worth to buy cheapest locked chip or go to K chip, everything in between with those 100Mhz differences really doesn't matter. So that way it could matter more. But overall, it isn't really impossible, since AMD doesn't compete in this sub-300USD market at all and Intel is free to squeeze it harder. Plus dropping prices latter is always better received than increasing them. So Intels plan could easily be just keep higher prices and drop them once AMD is ready to compete.

But then again, pricing is one of the things that can be changed in backstage before announcement so I wouldn't read too much into it. Still, I am looking forward for official word, plus benchmarks by independent third parties, Since even if leaked, that is still from Intel.

That being said, it is possibly fake too.

Who even uses geekbench for pc benchmarking.... its like instead of watching cpu reviews you visit user benchmark.

18:47 Sep-10-2021

this looks kinda fake to me, 12600 has same specs as 12400, but 12600K has more cores? K should be identical to non K, but unlocked.Benchmarks paint Intell 12th gen as too good to belive, besides even old cpu have kinda sus single core score.

18:14 Sep-10-2021

i5-12600 6/12 meanwhile the K variant is 10/16 :(

hoped to see a cheaper hybrid but nope.

17:16 Sep-10-2021

I'm very much looking forward to them, the i9's price is way too high, the i7s a bit too high, the i5's just right imo. Are they going to still be on "14nm"?

14? Pff... Only scrubs do 14nm - it's all about "~7nm++++++++++" 😄

18:00 Sep-10-2021

I mean, it's just poor marketing. They should have just changed numbers like TSMC does.

For example TSMC 12nm is 16nm which is 20nm, so technically 12nm is 20nm++ if intel were to name it.

Teh upcoming 6nm is 7nm++ as 7nm EUV is 7nm+ again if we go by intel naming schemes for process nodes.

But now intel are using the AMD athlon marketing scheme of naming their process nodes the same number as the one from TSMC it competes with.
