   the additional cores will give you more performance, otherwise you   
   better buy Turin.   
      
   Also, Intel has added 16 E-Cores to their desktop chips without giving   
   them the same amount of caches as the P-Cores; e.g., in Arrow lake we   
   have   
      
   P-core 48KB D-L0 64KB I-L1 192KB D-L1 3MB L2         3MB L3/core   
   E-Core 32KB D-L1 64KB I-L1            4MB L2/4 cores 3MB L3/4cores   
      
   Here we don't have an alternative with more P-Cores and the same   
   bandwidth, so we cannot contrast the approaches.  But it's certainly   
   the case that if you have a bandwidth-hungry load, you don't need to   
   buy the Arrow Lake with the largest number of E-Cores.
