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.

    Imagine, if you will, a world where one CPU will be pegged to 1.4v and instantly throttle, one will behave as expected, and one will explode into a fiery ball of death because the motherboard's required combination of Doctor Strange hand signs were mistranslated from Mandarin.

    You've just crossed over into...the Manual Undervolting Zone!

    That could be really interesting to see how they perform at a capped TDP.

    Power consumption for all benchmark runs would be great, possible just plotted into a single plot for all runs (power consumption on X, normalised benchmark performance on Y) to directly compare effective performance per joule. A task that completes faster at a higher power level than one that draws less power but takes longer may user less energy overall.

    I've purged a good dozen comments this afternoon. If you want to have fanboy fights, please go somewhere else.

    In the meantime, if you find yourself calling another poster a shill, fanboy, etc, you need to take a step back before you hit "post".

    Okay, nice to know, but why isn't there even one test of a non-K AL i7 and i5 with the stock cooler? Not everyone will or can shell out the $$$ for a K CPU, a feature-rich and expensive 690 board, and an AIO water cooling solution, and what can one get for a more regular budget, and how much performance does the extra expense buy? Just wondering, might be worth an article.

    That would paint a bit of a bad picture for Intel, as they're trying to pitch they have both affordable and top performance offerings in check.

    If you factor in whole platform cost, TCO, after available optimizations... bang for buck is a bit lacking.

    Please use current pricing, in the benchmark charts. Otherwise, simply don't include them.

    Your charts show the 5600X as $299, but its new price is $230. The 5800X is shown as $449, but it's now $350. And the 5900X is listed as $549, but it's now $450.

    That would show Intel in a worse light though?
  • mode_13h - Wednesday, March 30, 2022 - link

    I'm giving them the benefit of the doubt that it's a simple mistake. If you look at the conclusion, they seem to use street prices. So, I don't sense malicious intent.

    "Intel in worse light' haha. V5x price and dGPU price is crashing at end run as channels accelerate clearance to refinance for restocking. Sometime this week I will have the new WW GPU supply data which has shown not miner returns but enthusiast returns and some Nvidia and AIB stuffing to drag down inventoried pricing. mb
