Leaked Intel i9-12900K benchmark shows gains over the Ryzen 5950X

A new leak for Intel’s upcoming Alder Lake platform shows that the chips may outperform AMD’s Ryzen 5000 series. The benchmark shows the flagship Intel Core i9-12900K outperforming AMD’s Ryzen 5950X in Cinebench R20 by around 18% in the multi-core test and a staggering 28% in the single-core test.

Leaker OneRaichu said a qualification sample of the i9-12900K earned a score of above 11,600 in the multi-core test and above 810 in the single-core test in Cinebench R20. Those results put the processor firmly ahead of its direct competition from AMD, particularly when it comes to single-core performance.

In Guru3D’s testing, the Ryzen 5950X earned a multi-core score of 10,409 and a single-core score of 643 in Cinebench R20. That puts the 12900K at around 11% faster in single-core performance and 23% faster in multi-core performance.

The leaker says the results for the 12900K were gathered with a water-cooling without overclocking, so it’s possible the final score could be even higher.

PCGamer’s tests are even more favorable to the 12900K. Its testing of the 5950X reveals that the 12900K could be as much as 18% faster in the multi-core test and 28% faster in the single-core test. Even more interesting, the testing reveals that the 12900K is more than twice as fast as the i9-11900K that it will replace in the multi-core test.

The scores for the 12900K match a performance estimate that made the rounds last week. Between multi-core and single-core performance gains, the 12900K could cement Intel as the go-to brand for both gaming and productivity. That said, we don’t have any firm benchmarks yet.

The Core i9-12900K is rumored to come with 16 cores and 24 threads with a boost clock speed of up to 5.3GHz. Leading Intel’s Alder Lake platform, the processor adopts a big.LITTLE core design that utilizes high-performance and high-efficiency cores on the same processor.

This hybrid design shows up in many mobile processors. Instead of packing each core with a ton of power, the processor is able to delegate work to an appropriate core. So, a demanding task will go to the big core while a lightweight one will go to a little core, which improves the processor’s efficiency.

The upcoming Windows 11 is rumored to take advantage of this hybrid design, offering up to an 8.2% improvement in single-core performance. We don’t know what operating system the leaked benchmarks were using, much less the overall system configuration. However, Windows 11 could improve results further, particularly in tasks that stress a single core.

Intel hasn’t lifted the veil on Alder Lake yet. Although multiple leaks and rumors give us a decent idea of how the range is shaping up, we have to wait for launch and further testing to draw any firm conclusions. If the results are anywhere near what OneRaichu is suggesting, Intel could crawl its way back to the top after the disappointing Rocket Lake launch.

I tested Intel’s Core i5-14600K against its cheaper sibling. Don’t waste your money

Intel's new Core i5-14600K isn't a massive generational leap, as you can read in our Core i5-14600K review. No one expected it to be with Intel's 13th-gen CPUs already sitting among the best processors. The bigger question is if it's worth buying over last-gen's Core i5-13600K considering that both are readily available for around the same price.

I've tested both chips extensively across a range of productivity and gaming scenarios. The Core i5-14600K brings some minor improvements over its last-gen counterpart, but those looking to stretch their dollar the furthest are better off sticking with the Core i5-13600K.

The iPhone 15’s chip challenges Intel’s fastest desktop CPU — but there’s a catch
Intel Core i9-13900K held between fingertips.

Who would have thought that some of the best CPUs would face competition not from a desktop or laptop CPU, but from a mobile system-on-a-chip (SoC)? Well, the latest Geekbench 6 scores prove that it's possible. Apple's new A17 Pro chip, announced during the September 2023 Apple event and found in the iPhone 15 Pro and Pro Max, challenges AMD and Intel -- but there's a catch.

Yes, it's real. The Geekbench 6 test gives the A17 Pro chip a score of 2,914 in single-core operations, and that's mighty impressive for something that will end up in a smartphone. However, the generational leap is not that impressive -- the last-gen A16 Bionic chip is only around 10% behind in terms of single-threaded performance. The A17 Pro was built based on TSMC's 3nm technology, while the A16 Bionic is a 5nm chip, also made by TSMC.

AMD Ryzen 9 7950X3D vs. Intel Core i9-13900K: only one choice for PC gamers

The AMD Ryzen 9 7950X3D and Intel Core i9-13900K are undoubtedly two of the best processors you can buy, but they aren't equal. We threw both of the CPUs on the test bench to answer the age-old question: is AMD or Intel better?

Based on our testing, the Ryzen 9 7950X3D wins this bout, mostly on the back of the excellent gaming performance AMD's 3D V-Cache technology brings. Intel's Core i9-13900K still holds up, particularly in productivity apps, but Team Red takes the win this time around.
