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


(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.


(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.


(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.

    Need opinions:

    Should I go for a Surface Pro X SQ1, 128GB/8GB for $700 over a Surface Pro 7+ Core i5, 128GB/8GB for $800?

    I won't be using either for gaming...other than what's available in the Windows Marketplace.

    The Pro X allows for upgrading the storage. Don't know if the Pro 7+ allows that.

    No idea. I'd read through every review of the X you can find and see if it sounds like it'll fit your needs. Running Windows on an ARM-based CPU still sounds a little risky, but maybe it'll pay off in better battery life? Just a guess.

    Good luck with your decision.

    No offense, but....

    The reviews of these two CPUs seem just a tad.....'late to market'....!

    windows10/11 office 2016/2019/2021 Want to be our wholesaler?

    The best quality products and pre-sale and after-sale service, become our wholesaler, establish a long-term cooperative relationship, the greater the wholesale quantity, the greater the discount! ! !

    2-3% better on average then a Ryzen 5600X for twice the power consumption? Does not seem high performance for me.
