It's using DDR4 versus DDR5 in the Mac and a fraction of the memory bandwidth so will be interesting to see its performance on heavier tasks. Also looks like it has at least half the battery life if not far less when put under heavy load.

I do love this review though:

"It is a nice laptop but extremely noisy. Even when idle the fans are on all the time."

Memory bandwidth is nothing for most workloads. Besides a scant few Geekbench figures, I have genuinely never encountered a workload that was bottlenecked by my ability to transfer assets to the GPU. Is 100gbps of PCIe bandwidth not enough for your needs?
That's not true if you're actually using the ram though.

I remember memory bandwidth being the bottleneck when running large(ish) datasets for game worlds. It was so much that we put a lot of pressure on google cloud because we worried they wouldn't be able to compete with bare metal (since it's not usually measured, reported and can be non-guaranteed when you have neighbours).

Which review are you quoting?
