I think there may be a small typo:
QuoteAgainst Apple's M4 generation, the Arc Graphics 140T narrowly surpasses the standard M4 GPU (+7%) but falls significantly behind the smallest M4 Pro GPU, which is over 80% faster.
But the Steel Nomad Light chart (the M4 not on the other two) shows the Apple M4 ahead of the 140T by 7% (M4 3932 vs 140T 3692). If so, the above should read:
QuoteAgainst Apple's M4 generation, the Arc Graphics 140T is narrowly surpassed by the standard M4 GPU (+7%) and falls significantly behind the smallest M4 Pro GPU, which is over 80% faster.
