CPU Benchmark Performance: Power, Office, and Science

Our previous set 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.

For the remainder of the testing in this review of the Core i7-12700K and i5-12600K, we are using DDR5 memory at the following settings:

  • DDR5-4800(B) CL40

Power

(0-0) Peak Power

Comparing power draw to other competing CPUs, both the Core i7-12700K and Core i5-12600K are noticeably more power-efficient than previous generations including both Intel's 11th Gen and 10th Gen Core. Though at full-load with no overclocking, AMD's Ryzen 5000 and 3000 series processors remain much more power-efficient.

Office

(1-1) Agisoft Photoscan 1.3, Complex Test

In our office benchmarks, Intel's 12th Gen Core reigns supreme in Agisoft Photoscan due to its higher core frequency and IPC performance.

Science

(2-1) 3D Particle Movement v2.1 (non-AVX)

(2-2) 3D Particle Movement v2.1 (Peak AVX)

(2-3) yCruncher 0.78.9506 ST (250m Pi)

(2-4) yCruncher 0.78.9506 MT (2.5b Pi)

(2-4b) yCruncher 0.78.9506 MT (250m Pi)

(2-5) NAMD ApoA1 Simulation

(2-6) AI Benchmark 0.1.2 Total

(2-6a) AI Benchmark 0.1.2 Inference

(2-6b) AI Benchmark 0.1.2 Training

In the majority of our science-based benchmarks, both the Core i7 and Core i5 did well. The only benchmarks that didn't favor the 12th Gen Core series processors were in 3DPM 2.1, but more specifically in the AVX test.

    The USB problem you’re talking into something big was a big that only affected a small portion of users, don’t blow it out of proportion. And clearly your comment can be viewed as fan nonsense as Intel had its numerous own issues you’re completely ignoring here for your own sake. Suffice to say, PCs aren’t for noobs or people that want perfect experiences, they will always be a bit trouble and shoot.

    If you don’t like it, get a Apple maybe.

    Thank you for including the iGPU tests. It would be nice to see a few more data points like 720p/high and 1080p/low. Reply

    It's hard to take this article seriously when it compares processor prices when it spends more on memory for the Intel system than it does on the processor for the AMD system. Reply

    On the flipside, low-end boards for AMD are pretty lacking in IO. B660 boards are competitive with and often superior to X570 boards in IO.

    While obviously choosing a B350 board was my own fault (a couple years back), it's pretty painful to realize that the total available IO from my B350 board is already showing its age. There's tradeoffs here and you should acknowledge them.

    Point being, you can't normalize platform costs when the platforms are out of step anyway. There's no good way to equalize these platforms. Reply

    There are a range of motherboards for LGA1700. You can get Z690 MBs with either DDR4 or DDR5 memory slots. Sites have done comparisons between the two, we know that these Intel chips benefit from DDR5 and the IGP particularly benefits from it.

    There's no reason anyone sane would pair DDR5 with a low end i5.

    @dwillmore

    "There's no reason anyone sane would pair DDR5 with a low end i5", absolutely, and not one PC review site I'm aware has said this specifically, more generally focusing on the price premium.

    Another area that get's my goat that has not been said by PC review sites is if u'r sticking with Windows 10 late market (I am) the choice is V5x, M3x, Comet top bin or 9900K and if you must have Windows 11 'adoptive adaptive then its AL/RL or wait for Zen 4 validation . . . so simple to express simply and precisely. mb

    Finally a sign that Anandtech is coming back!
    I wanna see Exynos 2200 vs Snapdragon 8 Gen 1 analysis.

    Please note that only the "big" cores can be counted for performance - while the "little" cores are only relevant for saving energy ... Reply

    If your workload has enough threads to cover all cores, it should still better to have them. Reply
