Efficiency of the processor under full load in the Cinebench R23 (multi-core) benchmark. The benchmark result is divided by the average energy required (CPU package power in watts). The higher the value, the more efficient the CPU is under full load.

The chart below compares CPU Power Performance (performance / Max TDP) using the TDP numbers gathered from various sources. Higher results in the chart represent better power vs performance usage.

2023年11月30日 · Gaming PC Power Supply Wattage - "How Many Watts?" These CPU power consumption comparison charts will help you understand the full load power requirements of AMD vs. Intel CPUs for each...

In computing, performance per watt is a measure of the energy efficiency of a particular computer architecture or computer hardware. Literally, it measures the rate of computation that can be delivered by a computer for every watt of power consumed.

For consumers that aim to optimize power consumption, here are prediction curves for the performance/watt trade-off curve of selected CPU models. For each CPU model, the plot below shows a graph visualizing the confidence intervals of performance for each power target level (along the x-axis).

2023年1月6日 · Using our CineBench R23 Multi-Thread test results as our baseline for compute performance, we can see how well the Core i9-13900K scales when tasked with rendering. Using the stock settings...

2020年11月5日 · For AMD’s new Ryzen 5000 processors, most of them have a 105 W TDP, with a Package Power Tracking (PPT) setting of 142 W. For these processors, we can see our peak power consumption through our...

2022年1月28日 · Overall, Zen 2 is more power efficient at mid to low power levels. At higher power, Golden Cove is more efficient in vector workloads because Zen 2 doesn’t scale well as power increases. Compared to Gracemont, Zen 2 cores are better at all power levels, except when desktop Zen 2 cores hit an early voltage floor.

2023年1月6日 · For the compute side of our testing to determine how well the Core i9-13900K and Ryzen 9 7950X scale at different power levels, we've opted for a range of CPU-intensive benchmarks, particularly...

2024年9月19日 · Typically, processors have an efficiency curve where each additional watt of power draw provides less performance improvement. This is demonstrated by the 9950X, which is only about 13% more efficient than the 7950X, largely due to having the same performance while drawing 24 W less.
