Intel Core i9-12900T vs Intel Core i9-13900K: Comparison

Core i9-12900T vs Core i9-13900K: the total cores difference

These two are close on paper, and total cores is the only measure that separates them at all: Core i9-12900T 16 against Core i9-13900K 24. Core i9-13900K also leads on l3 cache, 30 MB on the Core i9-12900T versus 36 MB on the Core i9-13900K. L2 cache runs the same way, 14 MB on the Core i9-12900T versus 32 MB on the Core i9-13900K, another win for Core i9-13900K.

Who each one is for

The Core i9-12900T is the one to take for small-form-factor PCs and quiet builds, though it is the wrong buy for laptops and fanless designs. Take the Core i9-13900K for buyers on the mature LGA 1700 platform wanting flagship-tier Raptor Lake gaming and productivity performance at a lower price than the 14900K. Avoid it for new builds without an existing LGA 1700 investment, the newer Arrow Lake lineup offers better power efficiency on a fresh platform. Our rating of the Core i9-12900T (7.8/10): the Intel Core i9-12900T is a low-power desktop chip built for compact and quiet small-form-factor systems. Our rating of the Core i9-13900K (8.3/10): the Intel Core i9-13900K is still a powerful 24-core desktop chip, now largely matched by its cheaper 14th-gen successors.

What Core i9-12900T and Core i9-13900K have in common

Where they agree, they agree completely, performance cores, integrated graphics, socket, form factor and release year included, so the decision does not turn on any of those. They match on 9 further specifications as well.

Frequently asked questions

Do the Core i9-12900T and Core i9-13900K differ on efficiency cores?

Yes. Efficiency Cores reads 8 on the Core i9-12900T versus 16 on the Core i9-13900K.

Is the iGPU the same on the Core i9-12900T and Core i9-13900K?

It is. Both are listed at Intel UHD Graphics 770, so it is not a reason to pick one over the other.
