Also, I wonder if the two efficiency cores are just there for compatibility (maybe some OS functions are hard coded to only run on LP cores).
There are power optimized transistors and performance optimized transistors. You can't beat a power optimized transistor in a power consumption contest even if you massively downclock a performance optimized transistor because the latter leaks electrons more readily. So CPU designers have to choose between these two types of "libraries". Apple's tests must have shown that two LP cores are more than up to the task of handling normal OS background functions, plus it also allows them to enable maximum battery life.

Looking at the slide footnotes, it appears that the M1 Pro's GPU is straight up faster than a laptop 3050ti ("Discrete PC laptop graphics") while the M1 Max's compares very well with a maxed-out RTX 3080 Mobile ("High-end PC laptop graphics"). In an SoC that probably consumes less than 80w all-in, that's an engineering statement if there ever is one.
I suspect it may not be quite that fast, but even 3070 level performance mobile would be amazing. If only Microsoft could include ARM support in Windows 11 I'd straight up sell my desktop since it would be strong enough at gaming to not need one.

It's still a laptop and you want to extend battery life when doing minor tasks like web surfing and watching video.
The multiple on board encode/decode blocks handle all the heavy lifting for the later - hence the long battery life watching videos.

Here at the compared models apparently:

Compact pro PC laptopRazer Blade 15 Advanced (RZ09-0409CE53)NVIDIA GeForce RTX 3080 Laptop (95 W)
High-end PC laptopMSI GE76 Raider 11UH-053NVIDIA GeForce RTX 3080 Laptop (155 W)

So from what I remember of that graph it was slightly above the compact and slightly below the high end. So probably between the two in performance. Of course that is cherry picked. Still amazing performance though.

Well I just dropped $3400 with tax (edu pricing) for the 16 inch, 1tb ssd, 32gb ram, maxed out CPU. Even with a $1400 trade in that hurts a bit but hey, this performance looks insane and there's always the return window..........right?

....right?


...right guys?
Wow! You make a lot more money in college than I did (course, that was about three decades ago).

Hey, just a 1TB SSD with that budget?!

That was with a discrete GPU. They are using "Quad" (or "Eight" on the Max) channel LPDDR5.
LPDDR5 channels are generally 16-bit, so it would actually be 16 or 32-channel. They're using LPDDR5-6400 in x128 packages... which is rather exotic. And not at all what I was expecting seeing as Apple has never previously shipped a product utilizing LPDDR5. Pretty bonkers.

Yeah, when I saw the large squarish DRAM chips, I knew something was up. Pretty bonkers it is!
I wonder who did this custom work??

Per Anandtech Ryan Smith there are more transistors in this 5nm chip than the NVIDIA's Ampere A100 (currently Nvidia’s fastest gpu which is on 7nm.)

Now of course the Nvidia will be faster due to having a much higher TDP for Apple is putting the chip in a laptop, but I would hope the Apple silicon is fast in GPUnsince they are putting so much transistors in everything!

I'm not a college student, but I work with a college hence I still get the discount.

Honestly I may even sell my desktop, I rarely game these days.

You can put a lot of teraflops on a chip, being able to use them is another matter. Also, there is a process node of advantage.
Apple don't talk about "teraflops".

I believe that Apple could easily support ML upscale, but what about RT? PowerVR used to have RT cores in the past.

I really want to see some 3rd party benchmarks for the M1 Max, but it sounds like it's going to be the first APU in history where the 3D graphics do not suck. That's a huge milestone!

If there's one bad thing about this launch, Apple still doesn't care about gamers that buy Alienware/Razer sort of high powered gaming laptops. Their focus is still creative professionals. With so much GPU power available, would it have killed them to announce a native AAA title? I mean, everything is there, even a 120Hz display! All they needed was to get a major publisher on board (Take Two comes to mind) and gamers would be rejoicing everywhere right now.
