Intel har ju sin compilator som ger typ 43% bättre prestanda i specmarks och säkert annat med. Tror AMD hade tänkt visa upp cinebenchmark på sin 32 cores Threadripper men blev lite slaka i byxan när Intel visa upp sig
Du har ju ett problem med intels kompilator (ifall de inte har tvingats ta bort det då):

Will Intel be forced to remove the "cripple AMD" function from their compiler?
Many software programmers consider Intel's compiler the best optimizing compiler on the market, and it is often the preferred compiler for the most critical applications. Likewise, Intel is supplying a lot of highly optimized function libraries for many different technical and scientific applications. In many cases, there are no good alternatives to Intel's function libraries.
Unfortunately, software compiled with the Intel compiler or the Intel function libraries has inferior performance on AMD and VIA processors. The reason is that the compiler or library can make multiple versions of a piece of code, each optimized for a certain processor and instruction set, for example SSE2, SSE3, etc. The system includes a function that detects which type of CPU it is running on and chooses the optimal code path for that CPU. This is called a CPU dispatcher. However, the Intel CPU dispatcher does not only check which instruction set is supported by the CPU, it also checks the vendor ID string. If the vendor string says "GenuineIntel" then it uses the optimal code path. If the CPU is not from Intel then, in most cases, it will run the slowest possible version of the code, even if the CPU is fully compatible with a better version.
