Continuing with the bad news for Intel, Linux specialist site Phoronix Tests have shown that patches can have a significant impact on performance. Intel machines ran on average 16% slower with new installed updates and hyper-threading, compared with 3% for AMD chips.
To make matters worse, Apple and Google have advised Intel users to completely disable hyper-threading on Intel chips if they really want to be safe. This can result in a 40 to 50 percent reduction in performance, depending on the application. Again, AMD chips do not need to be patched for new bugs, and it is not necessary to disable Simultaneous Multi-Threading (SMT), equivalent to AMD at the hyper-threading of Intel.
Hyper-threading mainly concerns workstations and servers, performance-sensitive markets in which Intel realizes a large part of its processor sales. Phoronix said that "the impact of attenuation is enough to bring the Core i7-8700 K closer to that of the Ryzen 7 2700X", in terms of performance, depending on the system.
This is especially bad for Intel, as AMD is about to launch a state-of-the-art 7-nanometer chip set for desktop and server applications. Intel, meanwhile, still uses a near-old technology (in terms of microarchitecture) of 14 nanometers. Given the problems faced by Intel and the speed of its new chips, AMD could exceed its rival, in terms of performance, and seriously reduce its sales.
