AMD Athlon X4 is a series of budget AMD microprocessors for personal computers. These processors are distinct from A-Series APUs of the same era due to the lack of iGPUs.^[1]^[2]

"Richland" (2013, 32 nm)

Socket FM2
CPU: Two or four Piledriver-cores
GPU TeraScale 3 (VLIW4)
MMX, SSE(1, 2, 3, 3s, 4a, 4.1, 4.2), AMD64, AMD-V, AES, AVX(1, 1.1), XOP, FMA(4, 3), CVT16, F16C, BMI(ABM, TBM), Turbo Core 3.0, NX bit
