Apple introduced two new processors for Mac: M1 Pro and M1 Max. These self-developed Arm-based chips have been improved and are much larger than the M1 version launched last year, and integrate memory, CPU and GPU under one roof.
Apple even stated that its new GPU is compatible with Nvidia’s RTX 3080 mobile chip, Although you have to believe what Apple said. We also contacted Nvidia to see its opinion on the matter.
M1 Max is the larger of the two chips, or more precisely a system on chip (SoC), with 57 billion transistors, which means it is equipped with the most memory, the most cores, and claims to have the largest The performance advantage. It is a 10-core CPU with eight performance cores and two efficiency cores, a 32-core GPU and up to 64GB of memory.
Each GPU core has 16 execution units, and each execution unit contains 8 ALUs. This makes a 4,096 ALU GPU in the M1 Max.
with Apple says This is enough to provide “similar performance to the highest-end GPU in the largest PC notebooks, while reducing power consumption by 100 watts.”
Check its diagram to prove it. Keep in mind that Apple does not provide any indication of the benchmarks used to collect this data, only that it collects them “using selected industry standard benchmarks.” So, it looks exciting, but it’s not that useful.
The laptops that Apple evaluates performance are MSI GE76 Predator (11UH-053), Nvidia GeForce RTX 3080 mobile GPU with 16GB GDDR6, Intel Core i9 11980HK and 32GB RAM.
Therefore, let us try to understand the actual situation of Apple’s new GPU to better determine our actual expectations of the M1 Max.
Apple stated that the GPU in the M1 Max is four times faster than the GPU in the M1, and it turns out that it is exactly four times faster than that in the M1. The full eight-core M1 is rated at approximately 2.6 TFLOPS, so we are looking at the GPU in the M1 Max, which has an area of 10.4 TFLOPS.
This is actually a far cry from the 18.98 TFLOPS of the RTX 3080 Mobile running at the highest speed, which should be the case in the MSI GE76 Raider. In fact, Apple’s chip is closer to RTX 3060.
So how does Apple say that the M1 Max is much faster?
Well, this may boil down to the benchmark tests that Apple decided to run. The construction of the M1 Max chip, the large unified memory pool available for GPU and CPU, and even the programming language that uses metal, will have a huge impact on the performance of Apple and Nvidia’s chips in different situations.
M1 Max has a memory bandwidth of 400GB/s and can access a large amount of memory bandwidth. This means that any workload that utilizes all available memory bandwidth can perform very well on the M1 Max.
And we didn’t really indicate what was used for testing, this is the real key. I would like to say that it is a benchmark, and more representative of Apple’s desire for its M1 Max to be used in professional creative applications, and it is almost certainly not related to games.
That’s not Apple’s cup of tea. Although Apple will use gaming laptops here to compare it is interesting in itself.
In answer to my own question in the title: Should you trust Apple’s GPU performance statistics? There must be the truth behind the numbers, but the devil is in the details, we don’t have yet.
The bigger story in the Apple Mac launch event may be the touted power requirements of the M1 Max and M1 Pro, which are far lower than their competitors. Similarly, the environment determines everything, but from the already shrewd design of M1 to the use of TSMC’s latest 5nm process node, it makes sense for Apple to save so much cost while still filling so many transistors.
There is no doubt that these two chips are an impressive engineering feat, and they are also very amazing.Just don’t care about the price too much, M1 Max will at least let you down 3,499 USDAs for their impact on PC games, well, you may not hear more about them, but you can regard Apple’s current success and its Arm driver chip as a benefit of PC games, to some extent : If they kick Intel in Macs and put more pressure on Intel to provide bigger and better chips, it will certainly have it. This will only benefit many of us from buying PCs and laptops with Intel built-in.
