Arm chips will most likely replace Intel even for servers. I think we may se massive core count with lower clocked frequency chips as die shrink will be come too expensive.
“Rock's law or Moore's second law, named for Arthur Rock or Gordon Moore, says that the cost of a semiconductor chip fabrication plant doubles every four years“

- cbHXBY1D 8y agoThat's the idea behind Esperanto's 4096 core RISC-V CPU. It's run by Dave Ditzel and the creator of BOOM CPU.
- vardump 8y agoCPU side channel attacks, speculative execution leaks, throttling and cache effects, might eventually benefit the ARM server camp. Maybe instead of virtual machines we'll end up running (some) workloads on cheap, low power and isolated ARM CPUs, directly on bare metal without potentially leaky virtualization. Something like 4-16 GB of ECC RAM over 1-2 channels, quad core Cortex A73, A76 or similar. (Some ARMv8 designs are actually not that far behind of x86 chips in scalar performance anymore. SIMD (vector integer/floating point) is another matter, but I guess it's not impossible to slap a few 256 or 512 bits wide SIMD units in ARM designs.)
- chasil 8y agoI see this as unlikely. ARM was very late to the game with a 64-bit isa. With a completely free competitor in risc-v, and not much market penetration, what is the motivation for a customer to pay the licensing fees?

Many applications remain single-threaded, and until a parallel version is developed for all these applications, single thread speeds will matter.
