The M1 ultra has 800 GB/s memory bandwidth. That’s not very far off from the RTX 4090.
- pezezin 3y agoBut the M1 and M2 lines are system-in-package, with the memory soldered on the same package as the CPU, and thus not upgradeable.
- dontlaugh 3y agoNo GPUs have upgradeable memory either.
- pezezin 3y agoBut CPUs do, and if the GPU is discrete you can replace it.
- dontlaugh 3y agoAnd yet the GPU is most of the cost of the entire machine. Not much is gained by the modularity on the CPU side.
- pezezin 3y agoDepends on the machine. If you pair a RTX 4090 with a potato CPU then sure, if you go for something more reasonable, not at all. At least you need to consider the CPU, motherboard, and RAM.
