Intel accused of inflating CPU benchmark results::SPEC says Intel’s Xeon processors were using a compiler that artificially inflated the results of its industrial benchmark by as much as 9%.
You must log in or # to comment.
Oh, I thought that was assumed, because Intel always does that. At least I noticed it very clearly already back in the 90’s.
Everyone does it, it’s basically expected at this point that any manufacturer will announce that their new chip will run an infinite loop in fewer microseconds than the neighbouring one would.
Ah yes, the Snake oil merchants tried to sell snake oil…again
Again?
But I suppose it’s not that different to when they rigged an industrial phase-change cooler onto one of their CPUs, then pretended it could perform like an AMD CPU lol
Well, it could*!
*with an industrial cooling system
Wait, people trust corporate benchmarks?
Most of humanity is pretty clueless about IT in general and are just used to trusting who they buy from with zero critical thought or research.
Again?!
i will only care if they ever see consequences for it.
Very mixed on this. If the compiler is for example using stuff like constexpr in C++ to do major calculations at compile time instead of at runtime then yeah its cheating.
But on the other hand if its doing some Microarchitecture specific optmizations like reordering instructions or replacing certain instructions with others - as long as these are available to the public its fair game i.m.o…
The article states that the compilation was tailored for this specific task, which means it doesn’t represent how the CPU would normally perform it. So it’s definitely cheating.
A benchmark is not supposed to be a compiler optimization competition. If they showed both, and revealed it was optimized, it would be another matter.Even if the compiler was available to the public most software doesn’t use it, so the benchmark is still not representative of real world performance.
