the features listed at cpuminer startup to ensure you are mining at
optimum speed using the best available features.

Architecture names and compile options used are only provided for
mainstream desktop CPUs. Budget CPUs like Pentium and Celeron are often
missing some features. Check your CPU.
AMD CPUs older than Piledriver, including Athlon x2 and Phenom II x4, are not
supported by cpuminer-opt due to an incompatible implementation of SSE2 on
these CPUs. Some algos may crash the miner with an invalid instruction.
Users are recommended to use an unoptimized miner such as cpuminer-multi.
Support for AMD CPUs older than Ryzen is incomplete and without specific
recommendations. Find the best fit. CPUs older than Piledriver, including
Athlon x2 and Phenom II x4, are not supported by cpuminer-opt due to an
incompatible implementation of SSE2 on these CPUs.

can be found on Wikipedia.

(1) Haswell includes Broadwell, Skylake, Kabylake, Coffeelake & Cometlake.
(2) Rocketlake build uses cascadelake+sha as a workaround until Rocketlake
compiler support is avalable.
(3) Icelake & Tigerlake are only available on some laptops. Mining with a
laptop is not recommended.
(4) Zen3 build uses zen2+vaes as a workaround until Zen3 compiler support is
available. Zen2 CPUs should use Zen1 build.
* Alderlake is a hybrid architecture. With the E-cores disabled it may be
possible to enable AVX512 on the the P-cores and use the avx512-sha-vaes
build. This is not officially supported by Intel at time of writing.
