I don't know but I could see the possibility that maybe AMD really can use more throughput for mobile chips.
To spitball some figures, the rx7600 is 13b transistors, 165watts, and runs off 128-bit 288GBps GDDR6 memory. Or take 2017's rx580, but which was 256-bit GDDR5 good for 224GBps, at similar power.
An APU is going to be considerably lower power than either of these discrete gpus. I think I somewhat overestimated AMD's ability to scale up their APUs to be throughput limited, in most cases. The 256GBps LPDDR5X memory they're planning should offer a nice bump over where we are be pretty good.
I'm a bit surprised to see the memory bandwidth not being as constraining a factor as I had first guessed. It's also seemingly bizarre how overbuilt it makes Apple's memory setup look.
- dathinab 3y agoI mean it is a constraining factor for live on-the fly real time multi 8k-track video editing and similar ;=) It's just that most people don't do that on a daily usage basis. Maybe not a I need 800GiB/s constraining factor but definitely a I don't want just 200GiB/s constraining factor AFIK.
