... Core i 2nd, 3rd and 4th Generation CPU's have AVX (Advanced Vector Extension) instruction sets. Recent versions of Prime95 run AVX code on the Floating Point Unit (FPU) math coprocessor, which produces unrealistically high temperatures. The FPU test in the software utility AIDA64 shows the same results.
Prime95 v26.6 produces temperatures on 3rd and 4th Generation processors more consistent with 2nd Generation, which also have AVX instructions, but do not suffer from thermal extremes due to having a soldered Integrated Heat Spreader and a 35% larger Die. ... "
This is a 22 nanometer problem common to 3rd generation Ivy Bridge and 4th generation Haswell / Devil's Canyon processors.
For those of you who need proof, seeing is believing. Please download Prime95 version 26.6 - http://windows-downloads-center.bl [...] 1/04/pr...
Run Small FFT's for 10 minutes then compare your core temperatures with P95's latest version, 28.5.
Your core temperatures will test 10 to 20C lower.
En gros Prime95, au dessus de la version 26.6, est déconnant avec le 4790K.
