Is the Intel Core i3-6300T any good for video editing and graphic design?

Solution
I dislike saying any CPU is "too weak" to do anything because 20 years ago our processors were a lot slower than even today's ARM processors you find on phones, and I can assure you we did video editing on our computers back then. Any CPU can do any task, it just depends how long you're willing to wait.

On desktop processors (the breakdown for laptop processors is totally different):

i3 = dual core, hyperthreading, no turbo boost, 3MB cache
i5 = quad core, no hyperthreading, turbo boost, 3MB cache
i7 = quad core, hyperthreading, turbo boost, 4MB cache

At least that's how it generally breaks down. Intel has been mixing it up a bit with newer processors. The i3-6300T in particular has 4MB cache like an i7 (so do the Core M...

At least that's how it generally breaks down. Intel has been mixing it up a bit with newer processors. The i3-6300T in particular has 4MB cache like an i7 (so do the Core M processors for that matter).

So you've got two things going against the i3: No turbo boost, which is not that big a deal - just compare based on the specified clock speed instead of the turbo clock speed. And only a dual core, which is a huge deal. On multi-threaded tasks like video rendering, it'll be half the speed of an i7 at the same clock speed. (The integrated GPU is the same, clocked about 10% slower on an i3 than an i7, about 15% slower for an i3-T.)

That's the objective breakdown. Subjectively, the i3 should be fine for graphics design. It'll be marginal for video editing (one core for video decoding, one core for running the OS and editing program). And it'll be dog slow at video encoding. If you only plan to edit and encode the occasional home video, it might be tolerable (start the render, go to sleep). But if you plan to do video editing for school or work, get at least an i5, preferably an i7. Video rendering is one of the few tasks where hyperthreading actually helps significantly, making the extra money for an i7 worth it over an i5..
