I'm curious, and this is a side question, but on the topic of energy use, is it more likely that maxing out a GPU or maxing out a CPU will have the biggest power draw, and therefore affect energy bills more or run battery lower?
- neogodless 5y agoFor some examples, in my laptop the CPU is officially a 45W part though it can be configured to draw up to 70W. On the other hand, my GPU can be set to draw 115W. In my desktop, it's a 65W (AMD) CPU and 230W GPU. For an AMD consumer desktop, you wouldn't expect much higher than 125W power consumption from a CPU. But the new Alder Lake Core i9 advertises power draw as high as 241W. So you can end up with a more demanding CPU than GPU if you try.
- jb1991 5y agoI was thinking specifically in the context of the M1, which this article is about.
- neogodless 5y agoYup, and you won't get those specific numbers, so it may be helpful to use numbers that are available in other systems. Additionally, if you look at a chip diagram, you can see how much more of the transistor budget is used for the GPU cores than the CPU. https://images.anandtech.com/doci/17019/M1MAX.jpg https://images.anandtech.com/doci/17019/M1MAX.jpg From https://www.anandtech.com/show/17024/apple-m1-max-performance-review https://www.anandtech.com/show/17024/apple-m1-max-performanc...
