Doesn't it all boil down to bandwidth?
AMDs IGP are way less attractive because they use rather slow DDR4/5 memory while the M2 has blazing fast memory integrated in the package.
We're talking about 50 GB/s vs 400 GB/s. Nvidia's A100 has 1000 GB/s.
Memory bandwidth is usually the bottleneck in GPU performance as many kernels are memory-bound (look up the roofline performance model).
- brucethemoose2 4y agoThe AMD 6000 series has 128-bit LPDDR5 as an option, the 7000 series had LPDDR5X. This is similar to the M1/M2. The Pro/Max have double/quadruple that bus width. But they are much bigger/more expensive chips.
