Continuing Bad News for Intel, Linux Specialist Phoronix performed tests demonstrating that the patches can significantly affect performance. Intel computers ran on average 16 percent slower with the newly installed updates and enabled hyper-threading features than 3 percent on AMD chips.
To make matters worse, Apple and Google Intel users have advised to completely disable hyper-threading on Intel chips, if they really want to be sure. This can reduce performance by 40 to 50 percent, depending on the application. Again, AMD chips do not need to be patched for the new bugs and there is no need to disable simultaneous multithreading (SMT). This is equivalent to AMD's Hyper-Threading.
Hyper-Threading affects mainly workstations and servers, power-sensitive markets where Intel has a large share of CPU sales. According to Phoronix, "the attenuation effect is enough to bring the Core i7-8700 K much closer to the Ryzen 7 2700X in terms of performance," bringing out a range of state-of-the-art 7 nanometer chips for desktop and server applications, depending on the system. Intel still uses 1
