Is CPU graphics used in render

Question

I'm looking at upgrade options for my edit workstation. My question is with Premiere set to hardware encoding I know it uses my GPU card. But does Premiere also use the CPU on chip GPU if present as well as the GPU card.

The reason I ask is is there any advantage getting a CPU with on chip graphics or is it a waste of money when Premiere only uses the separate GPU card for encoding acceleration.

It depends on which hardware acceleration you're referring to. There are two completely different forms. The first, is GPU accelerated effects, like color corrections, Warp stabilizer, and some other effects. That one is (nearly) totally dependent on the discrete GPU card. The other, completely different form, is for H.264/5 "long-GOP" decoding/encoding. Which is dependent mostly on the hardware associated with the CPU. Especially as some Intel CPUs have the needed hardware, some don't, and I don't think any AMD CPUs do. This is affected also (apparently) with some by the accompanying on-board gpu chip. So ... is it H.264/5 long-GOP you're concerned with, or ... color corrections/Warp and other GPU accelerated effects?
