AMD's higher clock speeds compared to Intel's IPC overclocking.
AMD's higher clock speeds compared to Intel's IPC overclocking.
Although intel has a higher IPC stock intel never seems to be able to reach the frequencies stock or OC compared to AMD. Does this mean that even though Intel may have a higher IPC rating, an overclocked AMD CPU with more cores, higher cache, and higher base clock would be able to be overclocked to match the amount of instructions that intel is capable of? Or am i missing something/ false information? It also seems like the AMD is cheaper as well at the cost of higher thermal output and higher power consumption.
If the above is true i have no problem beefing up my cooling and running AMD,

There isn't a current Core i9 CPU with a clock speed between 3.0 and 3.5 GHz that beats the FX 9590 at 5 GHz in single-threaded tests. Therefore, despite the higher speeds of AMD processors, their much lower performance per cycle aren't enough to compensate.
The issue with AMD currently lies in the extremely low IPC value, meaning even a high clock speed like 6ghz on an overclocked 6600K or Skylake i7 6700k will still underperform compared to a FX 8350.
AMD is cheaper because they need to be priced lower to compete with Intel processors that are faster.
Overclocking is a gamble and I doubt you will be able to achieve a higher performing system with an AMD processor vs an Intel processor at the same price point. There is more than just IPC.
I think there’s some validity to what you’re saying. It’s possible to compensate for the lower clock speed in AMD processors by boosting the number of clock cycles per second through overclocking, but you must also be aware that AMD tends to overheat when exceeding 1.4 volts and lacks certain instruction sets compared to Intel.
However, AMD Zen is arriving this year with promises of better IPC and a more compatible instruction set if it replaces the current limitations. I’d hold off on deciding whether to switch to team red until we see some performance data from Zen before making that choice.
