Intel Core i5-12400T vs Intel Core i5-12490F: Comparison
What is the difference between Core i5-12400T and Core i5-12490F?
P-core boost clock is the dividing line, Core i5-12400T 4.2 GHz against Core i5-12490F 4.6 GHz. L3 cache runs the same way, 18 MB on the Core i5-12400T versus 20 MB on the Core i5-12490F, another win for Core i5-12490F. They differ on igpu too, Intel UHD Graphics 730 on the Core i5-12400T versus None on the Core i5-12490F. There is a split on base power as well, 35 W on the Core i5-12400T versus 65 W on the Core i5-12490F. There is a split on max turbo power as well, 74 W on the Core i5-12400T versus 117 W on the Core i5-12490F.
Which should you buy, Core i5-12400T or Core i5-12490F?
The Core i5-12400T suits small-form-factor PCs and quiet builds, though it is not the pick for gaming desktops and overclocking. Buy the Core i5-12490F for desktop gaming with a discrete GPU and budget-conscious builds, though it is the wrong buy for systems without a discrete GPU and HTPCs needing video output. Our rating of the Core i5-12400T (7.3/10): the Intel Core i5-12400T is a low-power desktop chip built for compact and quiet small-form-factor systems. Our rating of the Core i5-12490F (7.4/10): the Intel Core i5-12490F trims integrated graphics for a lower price, aimed at builds already running a discrete GPU.
Where the two are identical
Everything else lines up. Total cores, performance cores, efficiency cores, total threads and socket read the same on both, so those are not worth weighing. They match on 12 further specifications as well.
Frequently asked questions
Do the Core i5-12400T and Core i5-12490F differ on p-core base clock?
Yes. P-Core Base Clock reads 1.8 GHz on the Core i5-12400T versus 3.0 GHz on the Core i5-12490F.
Is the Socket Status the same on the Core i5-12400T and Core i5-12490F?
It is. Both are listed at Mature, so it is not a reason to pick one over the other.
