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.

    Note the difference : a closed platform design, an open cpu silicon design.
    You want to build a PC, you can't use an Apple chip. You want to run windows, you can't use an Apple chip. You want to add memory, a second drive, an input card?
    You are catching on.

    Let me guess, due to the unfreezing process, you have no internal monologue?

    Anandtech has done some of the best reviews of Apple Silicon on the Internet, your internal monologue notwithstanding. I'm hoping to see a new one of the Mac Studio with its M1 Ultra. If there isn't going to be one, I'd just like to know so I can stop checking every day.

    Andrei is gone, don't hold your breath. It's a skeleton crew at Anandtech now that leadership at Future has basically left the site to die.

    Future is speedily becoming another TechTarget, acquiring and discarding sites after they serve their revenue-devouring purposes. I wager AnandTech forums will be closed down much like all the TechTarget forums (BrightHand, NotebookReview, TabletPCReview, etc.) now are.

    Give it 5-7 years but the forums here will be closed as well. With Ian and Andrei gone, this site now has an expiration date.

    shoot -- I hadn't realized. What a shame :-(

    There are applications that run on both platforms - some of them (like Cinebench) are even in this review.
    Also, there was a rough comparison between the Apple mobile phone core performance versus Intel server CPU core performance a couple of years ago.
    So, plenty of prior examples for an Apple vs Intel article, even if it's M1 versus Zen3 or whatever else.

    Do you really need an review for that? If you want Apple you buy it, it’s good. If you don’t want Apple you won’t buy it anyway.

    We want detailed benchmarks. We want to know how good the Ultra really is, particularly how well CPU and GPU performance scale up to dual-die. We want to see Apple's claims on performance and efficiency tested. I'm never going to buy a Mac, but I still want to know if their architecture lives up to their claims.

    Since Apple is leading on the innovation front, this could be taken as a harbinger of what's to come for other CPUs and GPUs.

    Detailed analysis of leading-edge tech is/was what this site is/was all about.

    Did I talk to you? No. I realize you’re a huge nerd that has to comment on everything here. You don’t own this website and you should get a therapist for that, it’s a bit alarming what you do and not a good showing for this site.

    That said, I’m not gonna waste my time with you again. You should know why. Didn’t read your comment either.
