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).

ahh thats total system power draw, not just CPU power. The Max/Pro have a lot more I/O, bigger dies and higher busses. You can also see the single core power consumption being higher on the M4 Pro/Max vs base M4 in the chart too

Fair fair. Though I will note the relative difference is much more.

Yeah this one:
He gets 771 ST in CB 2026, but 8903 in MT.
Only 55 in Speedometer 3.1? Should be 60ish.

The numbers are all over the place.
I mean 771 vs Macworld getting 722? That’s almost a 7% difference.
 
Pardon me if this was already posted:

Mobile RTX 5080 on power vs M5 Max on battery running the CP2077 benchmark

Settings: RT maxed, no path tracing nor upscaling.

https://twitter.com/x/status/2031187382305759732

The MacBook resolution was 2336×1460 while PC was 2560x1440 (so macbook rendered 7% less pixel while being overall 15,5% slower (22.91 FPS vs 26.96 FPS), but this is an insanely good result for high level raytracing on battery.

One thing is benchmark graphs, the other thing is to listen to these side-by-side (one barely audible).

That stutter on the PC laptop... there's more to it than meets the eye. Great result by the Mac though.

Those pauses!

BTW, depending upon the settings, sometimes it's actually advantageous to run a benchmark with the machine unplugged, since battery charging can generate heat. OTOH, if set another way, sometimes an unplugged machine will run slower. So, It's strange that he ran one machine plugged in and the other not.

Curious to see dieshots.

I thought the new P-cores might improve nT power efficiency significantly, but that doesn't seem to be case.

I wouldn’t think there would be more efficiency to be gained fully loaded, both Apple’s previous cores have had efficiency no one could imagine up in laptop and desktop until November 2020. The e core efficiency is insane!

I think the new cores are for day to day efficiency gains by taking on more work that required the previous P cores to be running.

I think they will be like what Intel is trying to do with their e cores. Intel’s e cores had about double the SPEC scores of Apple’s, but using about 5 W versus Apple’s sub .6 watts. If that Chinese post is accurate Apple’s new cores will have about the same performance as a Mont, but at what wattage.

The other question I have is Apple has been using per cluster frequencies and power, if the new cores are really in one 12-core cluster, it would seem that would require more complexity in cluster powering.

Alex Ziskind’s video he indicated that not only could six cores stay off, but that they stayed off even during an extended compute demand.

Here we go again… Back in 2020 when the M1 came out, we got a wave of videos just like this one, telling us how great 8 GB M1 Macs were and how you could edit 4K video and compose on pro music apps on them. And it was true…

…but about 6 months later there was another wave, a smaller wave but a wave nonetheless, of regret videos saying that 8 GB works but causes problems. People would report huge slowdowns on bigger projects and random crashes that simply didn’t occur on 16 GB machines. IOW, going from 8 GB to 16 GB on otherwise identically spec’d machines meant the difference between crashing and not crashing. And yes, this was way back in 2021 when this second wave of videos came out. We’re in 2026 now.

Obviously the 8 GB Neo isn’t targeted at pros and it can indeed be used for 4K video editing and stuff like that, but for someone who actually wants to do this stuff more than once in a blue moon, they’d be better off just getting at least a MacBook Air even if they’re just in high school. The MacBook Air also has several other advantages such as Display P3 wide colour support and better battery life.

Meanwhile, I’m trying to convince the wife that my kid really doesn’t need a new laptop this year. If we can delay the purchase until next year, I might just do that and hope that Apple actually does release that 12 GB A19 Pro MacBook Neo in spring 2027. However, it would also depend upon what Apple does with the Back-To-School promotion this summer.
