You are. right.

I have missed the one-letter difference in the title.

For simple readers like me, fundamental one-letter differences must be spelled out explicitly.

[ A note about Consistency of Performance Evaluations ] That was really a challenge to be as Consistent as Possible because many things were simply outside of my control. For example, - It was Not possible to get Base Performance numbers for MKL on older platforms, like Windows 95; - Another Inconsistency is related to OpenMP-based multithreading Not available in full on older platforms. It means, that all Completed tests are Single-Threaded using OpenMP. However, it is very easy to scale all numbers by dividing by 2, 4 or 8, in order to get estimated performance numbers in case 2-core, 4-core or 8-core hardware systems. Tests on Windows 8 and Windows 10 operating systems are Not done at all.

I am sorry,  but the data is too raw to comprehend.

Comparing specific items, the noise seems to overwhelm the results.

Your first test,  MinGW C++ compiler v5.1.0 - Release - 32-bit ( LPS: IKJ ) - CPU P4 32-bit Windows XP ]

Sub-Test 1.1 - MxMultA1 - Classic 2D                        2.750 seconds
Sub-Test 1.2 - MxMultA2 - Classic 2D                        2.79700 secs

Sub-Test 2.1 - MxMultB1 - Classic 2D Transposed  - 98.26601 secs

 Sub-Test 2.2 - MxMultB2 - Classic 2D Transposed  - 98.26501 secs

Your second test: MinGW C++ compiler v5.1.0 - Release - 64-bit ( LPS: IJK ) - CPU IB 64-bit Windows 7

Sub-Test 1.1 - MxMultA1 - Classic 2D :                    8.92300 secs
Sub-Test 1.2 - MxMultA2 - Classic 2D :                    8.98600 secs
Sub-Test 2.1 - MxMultB1 - Classic 2D Transposed  0.98300 secs
Sub-Test 2.2 - MxMultB2 - Classic 2D Transposed  1.15400 secs

64-bit is 100 faster the 32 bit? this should mean a real revolution! But wait, other routines are 4 times slower?

>>...64-bit is 100 faster the 32 bit? this should mean a real revolution!... Sir, you shouldn't be too sarcastic because you're comparing: - 32-bit SSE2 codes ( compiled with ICC v12.x ) executed on 32-bit Windows XP with Intel Pentium 4 CPU ( more than 14-year-old technology! ) against - 64-bit AVX codes ( compiled with ICC 13.x ) executed on 64-bit Windows 7 with Intel Core i7 ( Ivy Bridge ) CPU ( more than 3-year old ). Every test case has a Title and look at first a couple of posts for more details.
