Remember Intel is market leader making full-custom CPU's with more money thrown at each one than these small companies have. They also optimize the heck out of single-core performance which most RISC multicores don't. I think it's one of those things where you have to choose best bang for buck supporting an oligopoly or sacrifice some performance/cash to encourage new product development. Market says it overwhelmingly favors the former.
- astrodust 10y agoEven in multi-threaded benchmarks, where it should shine, it's getting murdered. ARM is a very promising platform and there's no technical reason why it can't out-perform Intel. It's just a matter of engineering it with that intent. Right now it's primarily intended to be efficient and good enough for mobile phones.
- nickpsecurity 10y ago"Right now it's primarily intended to be efficient and good enough for mobile phones." Exactly. That's why RISC-V variants focused on raw performance still have a differentiator.
- nomel 10y ago> there's no technical reason why it can't out-perform Intel I think "engineering capabilities and experience" is a valid technical reason. But the real "reason" is most likely branch prediction and caching. I wouldn't be surprised if Intel's NetBurst microarchitecture was more complex than the entire CPU section of an ARM processor. I'm having trouble finding transistor count for the CPU section, for ARM.
