Memory options 8 GB and 16 GB. No 32 GB option (unless you go Intel).

It should be noted that the M1 chip in these three Macs is the same (aside from GPU core number). Basically, Apple is taking the same approach which these chips as they do the iPhones and iPads. Just one SKU (excluding the X variants), which is the same across all iDevices (aside from maybe slight clock speed differences occasionally).

With approximate napkin math given the an e core is about 1/3 the performance of a P core, giving the M4 about 6 P core power. 2 more P cores would be about 1250, therabouts top HX 370, X Elite range. M4 Max? Fuggedaboudit.

I think that M4 Max will get +2 E-core. Together with architectural enhancements, it can give +20-30% improvement. This will easily outperform the M2 Ultra.

Yes, it's so good there's no reason to make stuff up. And yet... he did.

I should clarify, consumes 1/3 of the power to reach a similar score. HX 370 full max is like 80W+ (forget exactly off the top of my head).

And I agree, no need to embellish.

X Elite was released late. It should have been released earlier, instead of holding numerous events with hasty and false promises to ‘get ahead of the industry’.

Well, I hope they live up to whatever promises they intend to make next year. It’d be weird to do what they did for v1 twice.

Leaked M4 MacBook Pro Appears for Sale on Russian Classifieds Site

In a continuation of the latest unprecedented leak, Apple's yet-to-be-announced M4 MacBook Pro has reportedly surfaced on Avito, a popular Russian classified ads website. The development follows recent videos from Russian YouTube channels showcasing what appears to be the unreleased laptop...

It seems multiple M4 MacBook Pro 16/512 GB units were available, listed at ~US$7500 each until the listing was removed by the site.

Damn, smuggling Apple products into Russia is apparently a really lucrative gig!

There is a whole review of it lol
...

This never happened before to Apple. Previously only to Google Pixels

I don't want to derail the thread or enter any political discussion, but this is to be expected: Russia is China's new best friend, and previously China and Google had issues over Google store. Given that these devices are built in China, I'm not surprised there are leaks to countries where companies have very little control, and I expect more in the future. There's no judgement on my side about this, just my thoughts. I like to read such leaked previews, even though I always wait for more official reviews before drawing any conclusion and making any decision.

I know. I wonder how the M4 Ultra will potentially outperform the new Zen 5 and ArrowLake CPUs.
Click to expand...
I honestly wouldn't care about the CPU in an Ultra. I would like to see how it will handle LLMs. It will have at least 256GB of VRAM, big enough for some very large LLM models.
