Anandtech is comparing M1 vs A14. It's high performance for a cellphone part.
That’s where they started, but their conclusion was beyond that.
Did you miss the part where they said the fact that a single Firestorm core can almost saturate the memory controllers is astounding and something we’ve never seen in a design before?
This isn’t only about A14 vs M1.
It’s not that LPDDR4X-4266-class memory is special; it’s been around for a while. What is special is that the RAM is part of SoC and due to the unified memory model, the CPU, GPU, Neural Engine and the other units have very fast access to the memory.
This is common for tablets and smartphones; it’s not common for general purpose laptops and desktops. And while Intel and AMD have added more functionality to their processors, they don’t have everything that’s part of the M1 system on a chip:
* Image Processing Unit (ISP)
* Digital Signal Processor (DSP)
* 16 core Neural Processing Unit (NPU)
* Video encoder/decoder
* Secure Enclave
There’s no other desktop such as the M1 Mac mini that combines all of these features with this level of performance at the price point of $699.
I don't think that's notable, sorry. I would expect that of any modern CPU.
> it’s not common for general purpose laptops and desktops
Well, yeah, because "memory on package" has major disadvantages. You (laptop/desktop manufacturer) are making minor gains in performance and power and need to buy a CPU which doesn't exist. Apple can do it, but they were already doing it for iPhone, and they must do it for iPhone to meet space constraints.
I think unified memory is the right way to go, long term, and that's a meaningful improvement. But as you point out, there is plenty of prior work there.
> they don’t have everything that’s part of the M1 system on a chip
They actually do! The 'CPU' part of an Intel CPU is vanishingly small these days. Most area is taken up with cache, GPU and hardware accelerators, such as... hardware video encode and decode, image processing, security and NN acceleration.
Most high-end Android cellphone SoCs have the same blocks. NVIDIA's SoCs have been shipping the same hardware blocks, with the same unified memory architecture, for at least four years. They all boot Ubuntu and give a desktop-like experience on a modern ARM ISA.
