My thanks to mikeburr and Greenhorn for the test results.

Another AMD ...

Why not? It is supposed to be quite a decent processor.

bit late ...but

It's never too late.

Later today I'll finish the revised version of the program. There are some small bugs fixed, the number of procedure calls is reduced and more features and instruction sets are checked.

As promised, here is the revised version of CPU. The new archive is called cpuNew1.zip and is under the first post of this thread.

I fixed some small bugs, reduced the number of procedure calls, and the application tests for more instructions and features. Here is the output on my large machine.

CPU strings:
------------

Processor Vendor String: GenuineIntel
Processor Brand String:  Intel(R)Core(TM)i7-7820XCPU@3.60GHz

Features by Processor and Operating System:
-------------------------------------------

Supported Instruction Sets: MMX  SSE  SSE2  SSE3  SSSE3  SSE4.1  SSE4.2  AVX  AVX2  AVX-512 F

It's safe to use the following AVX-512 extensions with this machine:
--------------------------------------------------------------------

AVX-512 DQ          : Vector Double Word and Quad Word
AVX-512 CD          : Efficient conflict detection to allow more loops to be vectorized.
AVX-512 BW          : Extends AVX-512 to cover 8-bit and 16-bit integer operations.
AVX-512 VL          : Extends most AVX-512 operations to also operate on XMM and YMM registers.

Any processor that implements any portion of the AVX-512 extensions MUST implement AVX-512 F.
Not every architecture has all the instruction sets built in. We've for example:

Knights Landing     : CD ER PF
Knights Mill        : CD ER PF 4FMAPS 4VNNIW VPOPCNTDQ
Skylake             : CD VL DQ BW
Cannon Lake         : CD VL DQ BW IFMA VBMI
Cascade Lake        : CD VL DQ BW VNNI
Ice Lake            : CD VL DQ BW IFMA VBMI VBMI2 VPOPCNTDQ BITALG VNNI VPCLMULQDQ GFNI VAES
Tiger Lake          : CD VL DQ BW IFMA VBMI VBMI2 VPOPCNTDQ BITALG VNNI VPCLMULQDQ GFNI VAES VP2INTERSECT

GFNI (Galois Field Affine Transformation), VPCLMULQDQ, and VAES are not AVX-512 features per se.
Together with AVX-512, they enable EVEX encoded versions of GFNI, PCLMULQDQ, and AES instructions.

Your CPU supports the following additional instructions and features:
---------------------------------------------------------------------

RDRAND              : Returning random numbers from an on-chip hardware random number generator.
RDSEED              : Loads a hardware generated random value and store it in the destination register.
AESNI               : Advanced Encryption Standard Instruction Set
VMX                 : Virtual Machine Extensions
FPU                 : Floating Point Unit on chip
VME                 : Virtual 8086 Mode Enhancements
DE                  : Debugging Extensions. Support for I/O breakpoints.
PSE                 : Page Size Extension
TSC                 : Time Stamp Counter. The RDTSC instruction is supported.
MSR                 : Model Specific Registers RDMSR and WRMSR Instructions.
PAE                 : Physical Address Extension
CX8                 : CMPXCHG8B instruction (compare-and-exchange 8 bytes) is supported.
APIC                : Processor contains an Advanced Programmable Interrupt Controller (APIC) on board.

Test results on as many different machines as possible are very welcome. Thank you.

Separate the CPI ID by a space, makes it easier to read.

Thanks go to Greenhorn, quarantined (another AMD processor  ), and Biterider.

Biterider,

Results of cpuNew1: 

For a standalone assembly language program this could of course be solved more elegantly. The individual procedures are written in such a way that they can be called with small changes from C++.
Each instruction set can then be checked from the high-level language via a variable during runtime. I added this to the C++ program yesterday and it seems to work. The moment of truth will come
when the program is run in Geneva at CERN. We will see. As we all know, the devil is in the details.
