Mobile i3-6006U CPU, Intel HD 520 iGPU, AMD Radeon R5 M330 dGPU: DPM Bug Issue
The Mobile i3-6006U CPU, Intel HD 520 iGPU, and AMD Radeon R5 M330 dGPU are popular components in many laptops. However, there is a known issue with the Dynamic Power Management (DPM) on some of these systems, which can affect performance and power consumption.
CPU and iGPU
The i3-6006U is a dual-core processor from Intel's Skylake family, with a base clock speed of 2.0 GHz and a turbo boost speed of up to 2.4 GHz. It has a TDP of 15 watts, making it suitable for use in thin and light laptops.
The Intel HD 520 iGPU is integrated into the i3-6006U CPU. It has 24 execution units and a base clock speed of 300 MHz, with a turbo boost speed of up to 1050 MHz. It supports DirectX 12, OpenGL 4.4, and OpenCL 2.0.
dGPU
The AMD Radeon R5 M330 dGPU is a mid-range graphics card from AMD's Radeon R5 series. It has 384 shader units and a base clock speed of 800 MHz, with a boost clock speed of up to 900 MHz. It supports DirectX 12, OpenGL 4.5, and OpenCL 2.0.
DPM Bug Issue
Some laptops with the Mobile i3-6006U CPU, Intel HD 520 iGPU, and AMD Radeon R5 M330 dGPU have been reported to have an issue with the Dynamic Power Management (DPM) feature. DPM is a power-saving feature that dynamically adjusts the clock speed and voltage of the CPU and GPU based on the workload. However, on some systems, DPM can cause stuttering, increased power consumption, and reduced performance.
The issue is caused by a bug in the AMD driver, which incorrectly sets the DPM state for the Radeon R5 M330 dGPU. This can be fixed by either updating the AMD driver to a version that includes the fix, or by disabling DPM in the BIOS settings.
The Mobile i3-6006U CPU, Intel HD 520 iGPU, and AMD Radeon R5 M330 dGPU are powerful components that can be found in many laptops. However, some of these systems may have an issue with the DPM feature, which can affect performance and power consumption. This issue can be fixed by updating the AMD driver or disabling DPM in the BIOS settings.
