You might be surprised to learn that dell "hpc engineers" (or maybe HPE?) have attempted to sell me hardware using that exact logic to compare servers.

- lillecarl 3y agoVMware still uses ghz for displaying load and compute capacity on your servers.
- DaiPlusPlus 3y agoWell, they're not wrong... Given a highly-parallelizable numerics job, and all other things being equal, a 20 core 2.0Ghz machine will run the job in the same time as a 40 core 1.0Ghz machine. ...though usually we'd just give it in FLOPS - though FLOPS doesn't describe non-float operation performance. Probably just a sales/marketing person who learned a new technical word and wants to sound knowledgable to the customer but it back-fires.
- zarzavat 3y agoAt the risk of torturing this analogy beyond recognition, it’s more like having an 8 core CPU but with a weak 150W PSU such that you can only run one core at a time.
- SecretDreams 3y agoAnalogy sufficiently tortured
- bee_rider 3y agoIs each core specialized to some particular type of task or something like that? Which would make this less silly of an idea.
- swyx 3y agoin my understanding with an 8 way MoE youre still running all 8 for every request. only if you’re making a router model then itd be the “weak PSU” analogy. and even then a sufficiently perfect router would essentially have to know enough about its routes to almost simulate them which idk if i can believe works
- Faaak 3y agoAmdahl's law though ...
- thfuran 3y ago...doesn't really bite you for embarrassingly parallel numerics work.
