About this tag
Arm64 benchmarking on WindowsForum.com focuses on how Windows on Arm performance is actually measured rather than assumed. Coverage centers on a Microsoft engineer's comparison of MSVC and Clang/LLVM compilation for Windows on Arm, arguing that compatibility is no longer the main obstacle when porting C and C++ code. Instead, the practical question is which compiler produces faster results and how developers should test their own workloads. The discussion highlights that benchmark outcomes vary by application, making generic claims unreliable. For developers targeting Arm64 devices, the takeaway is to measure real code with both toolchains before deciding.

    Windows on Arm: Clang vs MSVC Benchmarks Show Why You Must Test Your Workload

    A Microsoft engineer says Windows on Arm compatibility is no longer the hard part of porting C and C++ code. He says the real question is which compiler to use and what to measure. Gleb Khmyznikov, a Senior Software Engineer at Microsoft, makes that case in an interview with Analytics Insight...
