The upcoming Thinkpad X1 Extreme is going to give it some stiff competition. It's wielding the insurmountable RTX 3080, and it's priced very competitively.

But I'm just going to tell it to you now so we don't make the same mistake we have for the past 10 years of computer hardware discussions: specs don't matter. You could tell 90% of the people buying PCs with dGPUs about your 5nm GPU and next-gen power efficiency, but they won't care. They're buying them as gaming devices, general-purpose machines and game development laptops. I'd argue the market for Mac users and PC users has not radically shifted, just the hardware you're using. If we're here to talk smack about hardware superiority, this website would have been insufferable for the past decade, because there was quite literally a complete lack of professional dGPU Macs. Now that the tables have shifted slightly, I don't see why Mac users feel the need to crawl out of the woodwork and declare the game as changed, now that Prometheus gave them the gift of a laptop that doesn't throttle to hell.

People will still buy all sorts of computers. Lots of options will appeal to different people. Intel is finally being forced to actually complete. It's all good. My M1 Mac (not even M1 Pro/Max) is quite easily the best computer I've ever owned, but I have zero need to proselytize and simply do not care what you or anyone else use.

That doesn't change the fact that the above claim about "laptop Xeon chips" beating the pants off the M1 Max is delusional nonsense.

I have to comment on the RTX 3080 bit: I have used many PC laptops over my career, and currently have a Lenova with a fat, barnburner Nvidia dGPU. The GPU is literally never used, because the moment it engages my battery life falls to cartoonish levels (somewhere in the range of 40 minutes), the laptop becomes a space heater, and the fans turn into jet engines. This is the sort of "spec chasing" that the industry is addicted to, providing absurd, completely unreasonable solutions just so someone can boast. One of the things about Apple, quite contrary to your claim, is that they don't do that. When they provide something, it is meaningfully usable and useful 100% of the time.

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).
