CPU Settings

CPU Multiplier

CPU speed is determined by multiplying the CPU multiplier by the BCLK. Increasing the CPU multiplier will increase the internal CPU clock speed but will not affect the clock speeds of other components.

AVX2 Multiplier Offset

The AVX2 multiplier offset sets a negative offset for the CPU multiplier for AVX workloads. AVX is a more demanding workload, which reduces the AVX multiplier to ensure the maximum possible multiplier for SSE workloads.

AVX-512 Multiplier Offset

The AVX-512 multiplier offset sets a negative offset for the CPU multiplier for AVX-512 workloads. AVX is a more demanding workload, which reduces the AVX-512 multiplier to ensure the maximum possible multiplier for SSE workloads.

CPU Cache Ratio

CPU internal bus speed. Should be the same as the CPU multiplier.

GT Frequency

Sets the frequency for the integrated GPU.

BCLK Frequency

CPU speed is determined by multiplying the CPU multiplier by the BCLK. Increasing the BCLK will increase the internal CPU clock speed, but will also affect the clock speeds of other components.
