Another reason is the something like 150% memory bandwidth and I'm sure there are other simple wins along those lines.
The M1 isn't necessarily a win for Arm in general. Other manufacturers weren't competing before and its yet to be seen if they will.
- mhh__ 6y agoIt's the memory stupid!
- to11mtm 6y agoSpecifically, the memory -latency-. By going on-package there's almost certainly latency advantages in addition to the much-vaunted bandwidth gains. That's going to pan out to better perf, and likely better power usage as well.
- NathanielK 6y ago150% compared to what?
- jayd16 6y agoThe latest i9 and the latest Ryzen 9, ie the competition.
- NathanielK 6y agoIntel Tigerlake and Amd Renoir both support 128bit LPDDR4x at 4266MHz. Maybe you're confusing the desktop chips that use conventional DDR4? The M1 isn't competitive with them.
- jayd16 6y agoOh those are pretty new and I haven't seen any benchmarks with LPDDR in an equivalent laptop chip. Do you have a link to any?
