Because, presumably, the P-cores are even beefier.
Intel and AMD are still trying to gain time on the slow march to ARM (particularly Apple) catching up. Both of their long term strategies seem to differ (AMD edging back into ARM itself, Intel being a little more close lipped), but they can't lose their one major edge (raw performance) or potentially more users switch to an x86-excluded (and, more importantly, third-party excluded) platform (Mac).
- metadat 2y agoIs ARM really that special? Why do you believe this is the case?
- thunderbird120 2y agoThe ISA is much less important than many people seem to think. The RISC vs CISC debate is beyond outdated at this point because no modern architecture actually works strictly like either under the hood. Organizations who did x86 architectures historically had much more emphasis on performance while organizations who did ARM had more emphasis on low power devices. The lingering engineering consequences of that history and the experience of the organizations doing design are orders of magnitude more relevant than the difference in actual ISA.
- Dalewyn 2y agoARM is special in that it's the only potential, realistic competitor to x86 left in the entire industry. RISC-V? Only if you're a zealot breathing fumes for life energy, at least as things stand today.
- gary_0 2y agoThe interesting thing about RISC-V is that there are like 10 billion RISC-V microcontrollers out there that otherwise would have been ARM. So ARM has been moving into the PC/server space while RISC-V pushes in from behind, at the opposite end of the line from x86.
- cptskippy 2y agoRISC-V is disrupting ARM's low end, the pace it's occupied safely for decades. As RISC-V matures, it will move upstream along the same path that ARM did. The difference is that it will be easier to move because the transition to ARM is demonstrating that companies don't need to be locked to a particular ISA.
- deaddodo 2y agoARM is simply the ISA the industry is pivoting to and where most forward investment is going. I don't know where I implied it was special.
- pclmulqdq 2y agoIn all seriousness, the main advantage of the P cores is the wider vector datapath. They are much more set up for loopy "grunt work" like matrix math. Web serving probably doesn't need a P core, for example.
