What is CPPC in bios?
CPPC defined in the ACPI spec describes a mechanism for the OS to manage the performance of a logical processor on a contiguous and abstract performance scale. CPPC exposes a set of registers to describe abstract performance scale, to request performance levels and to measure per-cpu delivered performance.

Should I turn SMT off?
SMT is what AMD have on their processors as well as Intel but under a different moniker, Hyper Threading. It’s best you leave it enabled since disabling it can affect gaming performance.
What is down core control?
AMD Ryzen 7 processors comes with a nice feature: the downcore control. This feature allows to enable / disable cores. Ryzen 7 and Ryzen 5 chips use the same die, which is made up of two CCX (Cpu CompleX), each CCX having 4 cores. So disabling cores on Ryzen 7 makes it possible to emulate a Ryzen 5 CPU.

CPPC defined in the ACPI spec describes a mechanism for the OS to manage the performance of a logical processor on a contiguous and abstract performance scale. CPPC exposes a set of registers to describe abstract performance scale, to request performance levels and to measure per-cpu delivered performance.
How do I know if CPPC is enabled?
Users can detect to see if CPPC is enabled on their Intel system very easily. By going to the Event Viewer, selecting Window Logs -> System, and then going to a time stamp where the machine was last rebooted, we can see ACPI CPPC listed under the Kernel-Processor-Power source.

disabling SMT yields better CPU scores..for gaming this is almost unaffected (having it on or off), though you can observe that when SMT is off the CPU goes for higher sustainable boost clocks, that is why the loss of extra threads is almost negated..
Does SMT improve performance?
Abstract—Simultaneous multithreading (SMT) increases CPU utilization and application performance in many circumstances, but it can be detrimental when performance is limited by appli- cation scalability or when there is significant contention for CPU resources.
Is SMT good for CPU?
Simultaneous multithreading (SMT) is a technique for improving the overall efficiency of superscalar CPUs with hardware multithreading. SMT permits multiple independent threads of execution to better use the resources provided by modern processor architectures.
Does SMT increase power consumption?
With SMT enabled, the core utilization is expected to be higher, with more instructions flowing through and being processed per cycle. This naturally increases the power requirements on the core, but might also reduce the frequency of the core.

AMD Core Performance Boost controls whether the processor transitions to a higher frequency than the processor’s rated speed if the processor has available power and is within temperature specifications. NOTE: This option is available on servers with AMD processors.
What is Ryzen Cppc?
If you open up Ryzen Master in advanced view, it’d show you your best cores in a CCX/CCD compared to others, that’s basically CPPC. It defines which cores can push the highest frequency and which cores cannot.
Should I disable SMT for gaming?
SMT is what AMD have on their processors as well as Intel but under a different moniker, Hyper Threading. It’s best you leave it enabled since disabling it can affect gaming performance.
What is BIOS Cppc?
CPPC defined in the ACPI spec describes a mechanism for the OS to manage the performance of a logical processor on a contiguous and abstract performance scale. CPPC exposes a set of registers to describe abstract performance scale, to request performance levels and to measure per-cpu delivered performance.
What is Cppc Ctrl?
CPPC or Collaborative Processor Performance Control is a feature defined in the ACPI specification that allows the processor to define how an OS should operate it efficiently.
What is Cppc tag?
CPPC specifically is a mechanism for managing the performance of a CPU, which it does in part by referring to this ranking of cores. However, the ranking is ‘continuous, abstract, and unit-less’, meaning there is no indication of the specific differences between cores beyond saying which is fastest.
Should you disable SMT for gaming?
disabling SMT yields better CPU scores..for gaming this is almost unaffected (having it on or off), though you can observe that when SMT is off the CPU goes for higher sustainable boost clocks, that is why the loss of extra threads is almost negated..
Does disabling SMT lower temps?
On the temperature side of things, it is clear that the SMT Off mode again puts up a higher thermal profile. Temperatures this time peak at 66ºC, but it is clear the difference between the two modes. On the power side, we can see why SMT Off mode is warmer – the cores are drawing more power.
Does disabling SMT improve performance?
disabling SMT yields better CPU scores..for gaming this is almost unaffected (having it on or off), though you can observe that when SMT is off the CPU goes for higher sustainable boost clocks, that is why the loss of extra threads is almost negated..
Why does SMT have improved performance?
The performance gains from SMT vary depending on a number of factors: The scalability of the workload, the CPU resources used by the workload, the instruction mix of the workload, the cache footprint of the workload, the degree of sharing among the software threads, etc.
Is SMT better for gaming?

How useful is SMT?
SMT offers the ability to use smaller components lighter and more compact than their through-hole counterparts. This has allowed engineers to maximize space on PCBs, reducing product size without compromising functions or performance.
What is a SMT on a CPU?
Simultaneous multithreading (SMT) is a processor technology that allows multiple instruction streams (threads) to run concurrently on the same physical processor, improving overall throughput. To the operating system, each hardware thread is treated as an independent logical processor.

Ryzen boosting works on the basis of available thermal and power (from the VRM) headroom. It will boost to maximum clocks on light, bursty type loads and on a single core at a time. As the processing load increases, across multiple threads of execution, it will lower boosting to a mid-range clocks on all cores.
