Intel Compiler

[Brekmister]

Before the launch of Ryzen I would like to forewarn TechTubers such as LinusMediaGroup and the General Enthusiast of the Intel Compiler:

 

A lot of industry standard programs such as Adobe Creative Suite, PCMark and maybe some Games has been compiled by Intel Compilers that checks for the CPUID at runtime. if the CPUID does not match "genuineintel" then there are certain instruction sets that are disabled at runtime such as SSE2/3. So, when AMD was claiming that it is on par with Intel I7, that's a whole lot more than 40% IPC improvement over Excavator if they are assuming that you are using a piece of software that is compiled by Intel's Compiler

 

Or it may be the other way around, the benchmarks will be very depressing because of this shenanigan.

 

I am not trying to start a flame war over which Intel or AMD is better, I am trying to say that, AMD is pretty well working against a whole lot of odds especially when even the law can't help AMD against Intel's Anti-Competitive Behaviors (Yes, it's still going on, sadly which is BAD for all including Intel, AMD and, VIA fanboys) And be wary of benchmarking software results.

 

You may say that, "They should have fixed that by now!" and "This is really old news" You are right however, it's still isn't fixed even after the trial that was almost a decade ago.

 

I want to give credit to Agner, a person who discovered this and, a would be Testee in court in FTC vs Intel before it was settled out of court in a non-favorable way.

 

Here are some places to start:

Pricing for the Premium SDK: https://software.intel.com/en-us/intel-parallel-studio-xe/try-buy#buynow

Optimization Notice (Pretty well hidden, took me a while to find): https://software.intel.com/en-us/articles/optimization-notice#opt-en -- Point taken but a simple deletion of a check will fix it

Agner's blog: http://www.agner.org/optimize/blog/read.php?i=49#112

FTC Complaint (See Nature of Case #10): https://www.ftc.gov/sites/default/files/documents/cases/091216intelcmpt.pdf

 

With that I would love it for TechTubers such as LinusTechTips to investigate this matter. PLEASSSEEEE!

This old news, is it still relevant today? I had a look and it appears it is. Intel fuck you.

Good thing I use linux and GCC on my AMD computer. I want LTT to include linux kernel compiling in their benchmarks using open source compiler on an open source OS so theres no anti-competitive bias. Theres also few open source games they can bench mark that have improved a bit on the quake 3 engine. I wonder how much Intel pays LTT to not mention anything in this thread?

I know it is old news but as I was implying, this has a very very large impact on Ryzen, Windows 10 especially is filled with DLL's that are built with Intel's Compiler. (I just ran an application to patch all of that so far, results are pretty good on my desktop.) But yeah, on my laptops, I buy them with windows then replace that 5400 RPM laptop drive with an small SSD with Ubuntu or Elementary OS.

 

Intel, I know you have a business to run but, this is just plain unacceptable.

 

You know about open-sourced games? What about an open-sourced Vulkan game engine? That would be sweet!
