Flux Klein 4B: Q4_0 and Q2 quantization methods yield identical performance

A user on Reddit compared two quantization methods, Q4_0 and Q2, for the Flux Klein 4B model. Both methods resulted in the same processing speed of 12.89 seconds per iteration for a 4-step render. The user tested this on a system with 16 GB RAM, an i5-4590 CPU, and a GTX 750 Ti with 4 GB VRAM, noting that the system did not run out of memory despite the low-spec hardware and the use of a 2-bit quantization. AI

IMPACT Demonstrates that lower bit quantization does not always degrade performance on specific hardware configurations.
