I'm most curious about whether there is an actual difference on the die between the performance and efficiency cores?
Or is this just fancy binning? If you get a die with 10 working cores, assign the weakest 4 as E cores and the best 6 as the P cores? This would be a great value proposition for Intel & the customer, cores that aren't up to snuff are not a complete write off for Intel like previous designs.
- icegreentea2 5y agoThe P and E cores are totally different. Take a looksie here (annotated die shot of 12900k with 8 P and 8 E core): https://i.redd.it/lyhmdzo6c3w71.jpg https://i.redd.it/lyhmdzo6c3w71.jpg Golden Cove are P cores, Gracemount are E cores.
- gambiting 5y agoYes absolutely, but that i3 could still be a chip that physically has the E cores present but they failed in testing so they are just cut off.
- icegreentea2 5y agoAccording to here (https://www.techpowerup.com/review/intel-core-i3-12300/2.html https://www.techpowerup.com/review/intel-core-i3-12300/2.htm...) The i3 uses a different die ("H0" vs "C0" of the 12900K). The "H0" supposedly has 6 P cores and no E cores. This meshes well with Intel's product stack - everything 12600 and down is maxed out at 6P+0E.
