Architectural Differences

  1. Process Node: Intel uses the same 10nm processing node for both the Core i9 12900K and 12700K, as it does with all its Alder Lake, Raptor Lake, and Raptor Lake Refresh chips.
  2. Core Count: The i9 14900K uses 8 performance cores in conjunction with 8 efficiency cores for a total of 24 threads, while the Core i7 bumps this down a bit with 8 performance cores and 6 efficiency cores for a total of 20 threads.
  3. Core Clocks: The performance cores of the Core i9 12900K have a base frequency of 3.2GHz with a boost of up to 5.2GHz, while the Core i7 12700K has a base clock of 3.6GHz with a boost of up to 5GHz.
  4. Memory: Intel was the first player to introduce DDR5 memory to the mainstream, and we see this with these processors supporting both DDR4 and DDR5 memory at up to 3200MHz and 4800MHz, respectively.
  5. Socket: Both processors use the LGA 1700 socket, which Intel has kept consistent for the last few years in all its processors.
  6. TDP: Both the processors have a PL1 TDP of 125 watts, though the extra cores and higher core clocks of the Core i9 can make it draw significantly more power than its little brother.

Intel’s Alder Lake processors served to push the envelope forward with their performance, but how do the processors from this generation stack up against one another? Follow along with the Core i9 12900K vs Core i7 12700K comparison to find out!

Gaming Benchmarks – 1080p

To get an idea of the in-game performance of these processors, we have used an intricate test bench that allows both processors to be used to their full capabilities. You can take a look at the specifications of this test bench below:

Test Rig


CS:GO @1080p (Image By Tech4Gamers)
  • Both processors had excellent performance in CS: GO, as we expected. The 12900K had an average framerate of 645 FPS, while the 12700K bumped this down a little to 629 FPS. Our comparison kicks off with a 2.5% lead to the i9.
  • The 1% lows were also very close between the two chips, with the 12900K getting lows of around 153 FPS while the 12700K had lows closer to 149 FPS.

Cyberpunk 2077

  • The average framerates were only 2.6% apart in Cyberpunk 2077, with the Core i9 getting around 115 FPS, while the 12700K got around 112 FPS. Once again, the difference would go largely unnoticed by anyone playing on either processor.
  • The 1% lows hovered around 77 FPS on the 12900K, while the 12700K had lows of around 81 FPS, flipping our expectations and giving the i7 its first win of our testing.

Red Dead Redemption 2

  • Both Alder Lake processors once again perform similarly in Red Dead Redemption 2, with the i9 getting an average framerate of 145 FPS, while the 12700K had an average framerate of around 138 FPS, which comes out to a 5% advantage for the higher-tier processor.
  • The 1% lows were once again higher on the i7, around 75 FPS, while the i9 was a few frames behind with minimums of 72 FPS.

Microsoft Flight Simulator 2020

To better understand the performance of the Core i9 12900K vs Core i7 12700K, we will discuss the average performance of these chips in the subsequent sections of this comparison.

Average Framerate

Both processors had very similar performance in our testing. The average framerate of the Core i9 12900K reached around 268 FPS in our tests, while the Core i7 12700K was around 3.4% slower, with an average of around 259 FPS. This was a rather negligible difference, especially at the high framerates we experienced with both of our chips.

1% Lows

The two processors got within spitting distance of 1% lows, with the i9 being only 1.4% faster than the i7. The higher-end processor averaged minimums of around 104 FPS, while the 12700K’s average approached 103 FPS. 

All in all, these processors were neck and neck against each other in terms of overall performance.

The Core i9 ran around 11% hotter in our testing than the Core i7 12700K, though the temperature range of this processor was still perfectly reasonable. Unless you mess up your cooling solutions a lot, neither processor should pose a threat of thermal throttling.

Price And Availability

ProcessorMSRPCurrent Price
Core i7 12700K💲409💲272
Core i9 12900K💲589💲375

As of mid-January 2024, the price of getting a new i9 12900K on Amazon is around 38% greater than getting a new i7 12700K, as seen in the table above. The availability of these processors might be dwindling in the new market, though the market for used chips is flooded with these processors. 

As for the value proposition, the 3.5% higher performance of the i9 is very hard to justify with this high price tag. 

Editor`s Note

If you want these processors for a better price, getting a used CPU would suit you nicely. As of writing this article, eBay has the Core i9 12900K listed for under $200, which offers a much better price-to-performance ratio compared to the price of this processor on Amazon.
