Two dimensions is 100% better than one.

Measured on a different axis.

You can have authoritarian left Stalin's Russia) and authoritarian right (Nazi Germany). You can have liberal (i.e. non-authoritarian) left and right too.

It's clichéd, but the political compass explains the concept, but it's still only one extra dimension. It's still far better than just left Vs right.

The labels get confusing especially between countries, but left and right are normally viewed as being economic policy classifications, but you can have authoritarians on right and left and all need to be fought.

Don't make the mistake of thinking that left mean anti-authoritarian. Left or right is an economic stance, and is orthogonal to beliefs surrounding government rights Vs population rights.

It's a mixed bag. The smaller nodes have bigger problems with static leakage power, Vs dynamic switching power (which goes down)

...but you've got Microsoft writing the OS.

Power draw is not all hardware.

I think people believe that the ARM ISA brings a power efficient design but what really made Apple able to sip power on the M1 was a decade of phone processor design experience and full control of the software stack.

Don't confuse TFLOPs and TOPs. Especially when the latter is 4-bit integer operations.

Why would AMD make an ARM CPU? The power efficiency isn't related to the instruction set.

More over-cooked than half-baked.

Should have left it alone when it worked.

Disagree. You quite often have a fair degree of scaler code in between portions which are embarrassingly parallel. If you don't have a decent scaler core you are destined to be become bottlenecked on them. It's not that different to a CPU / GPU pairing. If one is under powered, it determines the speed of the overall system.

If you look at what a company like Tenstorrent is doing, they are designing high performance Risc-V cores as a side aspect of their main goal of doing array processors. The reason is because they couldn't find scaler cores on the market with enough performance to not bottleneck the system.

I think those will have to have fairly good IPC, otherwise they won't be able to keep the array processors fed with work.

Guess we'll see.
