ShiftIntrinsicGuide is a GUI for x86 intrinsic instruction information. It provides a searchable list of all currently available intrinsic instructions and combines it with real-world latency/throughput measurements from a variety of different hardware architectures (Intel and AMD).
It combines data from the following sources:
- Intrinsics from Intel Intrinsics Guide.
- Performance data from uops.info.
- Searchable list of all available x86 intrinsic instructions.
- Instructions searchable by:
- Intrinsic name
- Assembly instruction
- Required x86 technology level (e.g. SSE3, AVX etc.)
- Types operated on (e.g. float, 8-bit integers etc.)
- Instruction category (e.g. arithmetic, bitwise etc.)
- Displays information for each intrinsic such as:
- Intrinsic form
- Assembly instruction
- Required include header
- Required CPUID support
- Instruction description
- Instruction operation pseudo code
- Displays performance measurements such as:
- Latency
- Throughput
- uops
- Port usage
- Offline use: Data is directly scraped from the online sources on first run and cached for future use.
- Periodic data update checks (as well as manual)
Pre-built executables are available from the releases page in a single archive.
