| Can anyone tell me the difference between the Xeon Platinum 8280L and 8280M? They look identical. Same platform, same base and turboboost clocks, same cache, same....everything. |

Price is the only difference I can see

| According to Wikichip, the "M" suffix indicates a "large memory support" of 2 TB, while the "L" suffix indicated an extended memory support of 4.5 TB. |

I noticed that; I wasn't sure if it was a misprint or not. Seemed odd that the "M" large memory support one supported less memory.
So I guess that's the only difference. One supports an insane amount of memory, one supports a ludicrous amount of memory. M vs L? lol |

It has some logic in history context. First use of M index was with Skylake xeons and there was no L index, 0.75/1.5TB segmentation.
Then Cascade Lake xeons had three max memory size variants and introduced L index to denote the largest variant, 1.0/2.0/4.5TB segmentation.
There is large price premium for M and L. For example, 6240L is four (!) times more expensive than 6240. |
