CPU Benchmark Performance: Power And Office

Our previous sets of ‘office’ benchmarks have often been a mix of science and synthetics, so this time we wanted to keep our office section purely on real-world performance. We've also incorporated our power testing into this section too.

The biggest update to our Office-focused tests for 2023 and beyond include UL's Procyon software, which is the successor to PCMark. Procyon benchmarks office performance using Microsoft Office applications, as well as Adobe's Photoshop/Lightroom photo editing software, and Adobe Premier Pro's video editing capabilities. Due to issues with UL Procyon and the video editing test, we haven't been able to properly run these, but once we identify a fix with UL, we will re-test each chip.

We are using DDR5 memory on the 12th and 13th Gen Core parts, as well as the Ryzen 7000 series, at the following settings:

  • DDR5-5600B CL46 - Intel 13th Gen
  • DDR5-5200 CL44 - Ryzen 7000
  • DDR5-4800 (B) CL40 - Intel 12th Gen

All other CPUs such as Ryzen 5000 and 3000 were tested at the relevant JEDEC settings as per the processor's individual memory support with DDR4.


The nature of reporting processor power consumption has become, in part, a bit of a nightmare. Historically the peak power consumption of a processor, as purchased, is given by its Thermal Design Power (TDP, or PL1). For many markets, such as embedded processors, that value of TDP still signifies the peak power consumption. For the processors we test at AnandTech, either desktop, notebook, or enterprise, this is not always the case.

Modern high-performance processors implement a feature called Turbo. This allows, usually for a limited time, a processor to go beyond its rated frequency. Exactly how far the processor goes depends on a few factors, such as the Turbo Power Limit (PL2), whether the peak frequency is hard coded, the thermals, and the power delivery. Turbo can sometimes be very aggressive, allowing power values 2.5x above the rated TDP.

AMD and Intel have different definitions for TDP that are, broadly speaking, applied the same. The difference comes from turbo modes, turbo limits, turbo budgets, and how the processors manage that power balance. These topics are 10000-12000 word articles in their own right, and we’ve got a few articles worth reading on the topic.

(0-0) Peak Power

Regarding peak power, all three AMD's Ryzen 7000 65 W series for desktop topped out around 90 W under full load. This figure of 90 W was consistent throughout our power testing, which is within a couple Watts of AMD's Power Package Tracking (PPT) limits (~88W).

Looking at the power consumption of the Ryzen 9 7900 in more detail, we can see how it behaved under full load when running a workload using yCruncher. As we can see from the above graph, when the workload is called, and strain is placed on the Ryzen 9 7900, it immediately rose to 90 W and remained relatively consistent throughout the benchmark. and remained at the 90 W mark for around 193 seconds.

This was the same duration the benchmark took to complete, meaning that the Ryzne 9 7900 remained at its peak power for the full duration.

In our office and productivity benchmarks, the AMD Ryzen 9 7900, as expected, performed the best out of the three chips. All three chips in each of the office-based workloads comfortably beat out the Ryzen 9 5950X, which is impressive given the Ryzen 5 7600 is a 6C/12T part at 65 W TDP beating out a much beefier Ryzen 9 5950X that is a 16C/32T part, albeit on an older architecture.

    The multiple tests where the 7900 is beating the 7950X by large (>5%) differences in game tests makes no sense and makes me concerned for the repeatability of the test suite. There is nothing (cache, clock speed, architecture, TDP, NUMA) that is inferior on the 7950X compared to the 7900 but somehow it loses by a large margin in many game tests.

    in your conclusion "Of course, users on a budget may want to pair up a Ryzen 5 7600 with a card such as an AMD Radeon RTX 6600"

    no RTX on the 6600 afaik ;)

    Those power consumption numbers are amazing.

    While you can make the argument that a "65W" AMD CPU consuming 90W is misleading, at least it's going to be consistently 90W regardless of which model you choose...

    Doesn't it become really weird to talk about efficiency while only comparing to TDP and not actual power consumption for the load? Not everything hits TTP as yCruncher does either.
    Preferrably the score in each result should be normalized to actual power consumption, or something similar. Even that has its issues though, since the balance between performance and efficiency is somewhat tuneable.

    Seconded! Or write the AVG power for the task. Ex: Cinebench: 7950X (214W) xxx.xxx point

    Performance difference is not that much! I going with the 7600 for internet surfing, watching streaming videos and email!😁👍

    I was expecting that all along, so I'm glad it's confirmed. Now just to find sensible AM5 MBO at the right price :-/
  • James5mith - Tuesday, January 10, 2023 - link

    Real question: Why do CPUs no longer idle in the 800MHz-1600MHz range? Is there too great a change in the multiplier to hit max turbo at this point? Otherwise, what's the point at idling around 3.6GHz?

    It seems like a waste of power.

    The cores are gated such that they are at 0hz when idle. The clock shown in Windows is just the speed the core ran at when it last reported.

    Goodness Anandtech do better, ditch the bizarre memory policy and do some PBO testing…
