The last canonical example of Intel refreshing their naming convention was with their Xeon line up which is now utterly incomprehensible, at a glance you used to be able to understand what was going on;
EX-YZZZ vA
E3 - Rebranded Desktop Class parts with ECC support
E5 - High-Desktop & Regular Multi-Processor Server parts
E7 - High-End Multi-Processor Server
Y - Denotes Socket Support.
ZZZ - Denotes a model number, indicating from low to high increases in features, cores and/or clock speed.
vA - Denotes Generation.
Xeon E5-2980v2 - is a high-core count server processor for use in dual socket servers, belonging to the Ivy Bridge Generation of parts.
The new naming "convention" is as follows - from a glance can you identify any information from this;
Xeon Bronze 3204
Xeon Silver 4214R
Xeon Gold 6212U
Xeon Gold 6342
Xeon Platinum 8280
Xeon Platinum 8380
Xeon W-2295
Bronze, Silver, Gold, Platinum - are so unclear as to be meaningless - there are dual socket Silver processors more capable than some Gold processors.
W prefixed parts are Workstation parts.
The First Digit bears no connection to anything (except in the platinum series where it denotes 8 socket capability), perhaps PCI-E Lanes?
The Second digit apparently denotes generation.
The Suffix denotes that it's only capable of running in a single processor configuration - except when it doesn't.
Ohh, and the 'E3-**** v*' convention still stands for desktop rebranded parts.
It's a complete mess.
- matja 4y ago> The First Digit bears no connection to anything One pattern is: If first digit is 3,4,5 then it has one AVX512 FMA unit, if it is 6,7,8 then it has two. ...except the 5122 (2), 5219Y (2), 5222 (2) and 6122 (1)
- Tsiklon 4y agogood shout - I'm not so up to speed with what AVX512 can accelerate, but is it such a distinctive feature that it warrants a full delineating model number?
- adgjlsfhk1 4y agoan extra avx512 fma unit means it can do twice as many z=a*b+c instructions per clock. this only really matters for matrix multiplication (for anything else you are memory bandwidth limited), but 2x matmul performance is a really big deal for hpc
