Family 15h (also known as fam15h, or ambiguously as fam15) is a family of AMD microprocessors corresponding to the Bulldozer, Piledriver, Steamroller, and Excavator microarchitectures.
"15h" (15-hexadecimal) is most correctly pronounced as "one-sixteen five", but most people say "fifteen‑aitch".
Like other AMD family names, "15h" is a mostly-arbitrary, somewhat-sequential number, returned by the CPUID instruction. The number 15h corresponds to the value 21, meaning that "Family 21" would also be a valid, if confusing, name for these CPUs. "Family 15" could confusingly refer to the Family 0Fh (K8 CPUs, first released in 2003).

Notes and Status
- All x86 CPUs include proprietary microcode, in ROM on the CPU itself. Later vendor-provided patches, which update part of this microcode, can be loaded at runtime - these patches are proprietary blobs.
- All Family 15h CPUs are vulnerable to speculative execution exploits if a microcode patch is not loaded.
- Apart from the above, Bulldozer CPUs are generally stable even without microcode patches.
- A microcode patch is strongly recommended for Piledriver CPUs, because of known virtualization-related bugs in their ROM microcode.
- Trinity APUs and Richland APUs additionally require the SMU firmware blob to run. The SMU (System Management Unit) is a microcontroller inside AMD SoCs/APUs that handles low-level platform management: power, clocks, voltage, thermal control, power-gating, and related sensors and interrupts. The firmware for this microcontroller is a blob, included as a large array in the Family 15h AGESA. Orochi platforms do not require this blob.
