Intel's i5-12400 Six-Core Alder Lake CPU delivers excellent performance in leaks

That's a high single-threaded Cinebench Score for a low-end processor.



Read more about Intel's leaked i5-12400 CPU benchmarks.

Looks very promising! I'm just wondering if CPUs with big-little-configs could potentially lose some performance when switching workloads between those types of cores if that is even possible. Or could there be a short "thinking second" while the CPU decides on which cores a software should run? OR or or is this all done by the OS?

Windows 11 was released for that purpose, and Intel is also releasing Thread Director to cover for Microsoft's incompetence. Most tasks should be run with one or other exclusively. Few tasks like rendering will have hybrid approach, like we see in CPU/GPU hybrid benchmarks (Cycles, V-Ray).

It's not to cover for anything. Idk why you keep posting that at every opportunity.

It's Intel's SDK for kernel developers to best take advantage of their hardware. They release stuff like this all the time you just don't hear about it. It was also built alongside with MS. They worked together to take advantage of the thread director hardware. This is new in the non mobile/traditional x86 space. Mobile has had this for over a decade. That's a lot of experience to leverage.

It's like complaining MS is incompetent with AMDs Zen architecture when it launched because it wasn't threading correctly. Yet over time is now doing so just fine. And to be fair, this alder lake is more complex.


On point though, this score is impressive as Mark said considering it's not the highest end.

I did mention it once but it was as a response to a question that had three options. Out of those three Microsoft was the correct answer.

This is a trillion dollar company that has some of the greatest minds on the planet working there. For them to have so many broken things that don't get fixed is just comical. iOS and Linux have things corrected very fast, so it can be done. Microsoft deserves and needs every single bad post and press that it can get.

If Intel was sure that Microsoft scheduler would work they wouldn't invest resources into making Thread Director. And Intel was definitely involved in scheduler development. Because it is more likely to be broken than it is to work perfectly Intel made their own solution because they need 12th gen to perform to it's best right now. They can't wait like AMD did for months to get performance on Windows, because AMD will have a response in that time.

Since this is getting off topic the most important thing is that we have a fight on. If we see AMD and Intel dethroning each other every year it will be amazing.

And if these leaks are true this CPU could be amazing for pretty much every gaming PC.

One side might speculate that Intel has Thread Director ready since it's absolutely necessary for them.


Others might speculate that AMD didn't have an in-house solution ready to fix the Windows scheduler since their software department is rather lacking. :P

You're just completely misunderstanding Thread Director. It's a hardware solution Intel built. They built a SDK for OS kernel developers to use. All it does is report to the OS Scheduler. It's up to the OS to handle how to thread it. Intel worked with MS on this part alone for big/little architectures. It has nothing to do with anything else.
Not even apple or Linux devs would be able to get it working quickly if Thread Director software was MIA. They'd just be guessing how to thread or what the CPU itself wanted to do.

As far as i'm aware Intel have more software engineers than most other companys and write a large chunk of windows with microsoft on-going hence why Intel generally get very well supported in windows, amd lack that software side somewhat thought that was common knowledge.

Will be interesting to see how AMD's V-Cache upgraded Zen 3 CPU's in January hold up against Alderlake.
