The video provides an in-depth comparison of power consumption and efficiency between Intel's 13th Gen CPUs and AMD's Ryzen 7000 series, focusing on real-world applications such as photo and video editing, rather than theoretical maximum power usage.
Intel's CPUs generally demonstrate better performance per watt and lower idle power consumption than AMD's, especially in workloads like Premiere Pro and Lightroom Classic, where Intel's iGPUs contribute to efficiency. The Intel 13900K, for instance, outperforms the Ryzen 7950X in several scenarios, offering higher efficiency and lower electricity costs over a year, though the cost savings are minimal.
Power consumption and cooling requirements are also discussed, highlighting the necessity of high-end cooling solutions for Intel's CPUs, particularly when unrestricted. Various testing metrics, including both hardware and software power measurements, underscore the challenges in obtaining accurate efficiency data but affirm Intel's overall efficiency advantage.
Ultimately, while both CPU brands have their strengths in specific applications, Intel's lineup provides a generally better performance-to-power ratio, making it a more cost-effective choice for creators, with minimal long-term cost differences between the two.

In this part of the video, the presenter discusses the real-world power consumption and efficiency of Ryzen 7000 versus Intel’s 13th Gen CPUs. They express concern over Intel’s 13th Gen CPUs consuming over 300 watts at maximum usage and emphasize the importance of understanding power efficiency in realistic workloads instead of just focusing on maximum power usage. The presenter highlights that neither AMD nor Intel provides the complete picture regarding power consumption. They explain that performance per watt and average CPU utilization are more relevant metrics, particularly for creators whose workflows typically do not utilize 100% CPU power. The segment also touches upon how knowing maximum wattage is crucial for determining appropriate cooling solutions for these high-power CPUs.

In this segment of the video, the speaker discusses the cooling requirements and power consumption of Intel’s 3900K and AMD’s 7950X processors. They explain that, without applying Intel’s power limits, high-end coolers are necessary due to the significant power draw (up to 253 watts for PL2 limit) and heat production. Conversely, applying limits can allow the use of less powerful coolers while sacrificing some multi-core performance. The speaker finds that with an ASUS motherboard, the Intel 3900K can pull over 300 watts when fully utilized. Additionally, Intel processors have very low idle wattage due to their efficiency cores, contrasting with AMD, which idles at much higher wattages. For benchmarking, the speaker tested programs like Lightroom Classic, which uses a mix of single-core and multi-core performance, reflecting real-world workflows.

In this segment of the video, the speaker discusses the testing of different workflows and software, focusing on CPU efficiency and performance per watt. They explain that Photoshop is primarily single-threaded with some multi-thread capabilities, while Premiere Pro has a mixed workload involving high CPU usage and some GPU. The speaker chose these CPU-focused tasks over others like Resolve (which is GPU-heavy) or Blender (mostly CPU-intensive) to provide a clearer picture of CPU efficiency. They also excluded gaming tests, as the channel does not focus on gaming.
The testing methodology involved using PugetBench benchmarks for Lightroom Classic, Photoshop, and Premiere Pro, to provide consistent and repeatable tests of the CPU’s single-core and multi-core performance. During testing, power consumption was measured using HWinfo, and OBS was used for screen recording to simulate a real creative workflow with additional background processes.

In this segment, the presenter discusses the results of a comparison between hardware and software measurements of power consumption. The data displays test scores, minimum and maximum power draws, average power consumption, performance per watt, and energy consumption over a year. The results illustrate performance differences, notably in Premiere Pro workflows. Intel CPUs top the charts for performance per watt, followed by AMD CPUs. The Ryzen 5, 7, and 9 rank in descending order of efficiency. The 3900K shows superior performance per watt compared to the 7950X, attributed to lower minimum power consumption.
00:12:00
In this part of the video, the discussion centers around power consumption and performance efficiency of different CPUs in various applications. It is noted that Ryzen CPUs are less power-efficient compared to Intel CPUs in Premiere Pro, with Intel’s iGPU providing a significant performance advantage. The Intel 12600K even outperforms the Ryzen 7950X in overall scores. In Photoshop, the 12600K and 13600K lead in performance per watt, but Ryzen CPUs show strong single-core performance, with the Ryzen 7600X outperforming the Intel 13900K. In Lightroom Classic, Intel CPUs dominate the charts, while Ryzen CPUs lag, primarily due to higher minimum power consumption.
00:15:00
In this part of the video, the discussion centers on the power consumption and electricity cost differences between Intel and Ryzen CPUs, particularly highlighting the Intel 13900k versus the Ryzen 7950x. It is noted that Intel CPUs generally have higher performance per watt and lower power consumption compared to Ryzen CPUs.
A comparison of annual electricity costs reveals that the Ryzen 7950x would expend about £21, whereas the Intel 13900k would use approximately £16. This difference, only around £5 annually, is minimal. This small cost gap suggests that any potential savings from lower power consumption with AMD systems are insignificant.
Further comparisons are made using specific applications like Photoshop and Lightroom Classic, indicating small differences in electricity costs, reinforcing that the actual cost difference over time is not substantial. The video also mentions that most workflows, including video and photo editing, do not fully utilize the CPU, thus the annual cost difference remains minimal.
Overall, the key point is that the performance and power consumption differences between Intel and Ryzen CPUs result in only a minor annual electricity cost difference, making it an insignificant factor in choosing between the two.

In this part of the video, the presenter discusses the challenges of accurately measuring power efficiency, comparing hardware versus software testing methods. They acknowledge that measuring power draw from the EPS plugs of the CPU socket would provide more accurate results but note the high cost and complexity of such equipment. The presenter points out that EPS plug measurements incorporate additional factors like motherboard power delivery efficiency, which affect overall power usage, not just CPU consumption. They also mention looking for a tool that can measure average power efficiency over time but haven’t found one yet.
To present their findings, they used simple wattage meters to measure power consumption from the wall during Lightroom Classic tests on two systems: the i9 13900k and the 7950x. The i9 13900k used 0.055 kilowatt-hours and scored 1917 points, while the 7950x used 0.67 kilowatt-hours and scored 1820 points. They conclude by explaining that despite software measurement inefficiencies, the relative performance differences remain consistent.
00:21:00
In this part of the video, the speaker discusses the performance-per-watt-hour results for Intel and AMD Ryzen systems. It is noted that AMD Ryzen used 27.16 watt-hours while Intel used 34.8 watt-hours. The AMD system had a more efficient power supply (80 Plus Platinum rating) compared to Intel’s (80 Plus Gold), giving AMD an efficiency edge. The speaker explains that using the same power supplies for both systems would slightly favor Intel. However, based on extended testing and data collection, the speaker concludes that Intel provides better performance per watt for most creators, except in specific scenarios like Blender render where AMD might excel. The difference in idle power consumption, which is lower for Intel, makes it a better pick budget-wise for typical usage scenarios. The speaker advises that the real-world financial savings between the two CPUs might not be significant and directs viewers to a build guide for creating a cost-effective creator PC. Lastly, viewers are encouraged to share their thoughts in the comments.
