i9-13900K appears on CPU-Z Validator: An engineering sample of the suspected i9-13900k was validated by the CPU-Z validator on the 20th of July. We don’t know who submitted the results, as the name of the publishing system just reads DESKTOP-4BR4UIF. So it really could be anyone, from Intel themselves, to a third-party early tester.
Now read: Intel 13th gen, what we know.

This leak is a gold mine of information, and it also confirms the rumors that Intel’s 13th gen will also support DDR4 RAM, as we covered in this Gigabyte motherboard article.
The leak
The leak came to light when accurate leaker @TUM_APISAK posted about it on their Twitter account. Here is the original post on the CPU-Z Validator website.
Performance
In this post on CPU-Z’s website, we can see the suspected 13900K engineering sample has been given some performance numbers, as well as some new and exciting information about its operation.
Single core performance

As you can see, the suspected 13900k engineering sample scored a very respectable 846 points in CPU-Z’s benchmark. This is a full 27 points ahead of last gen’s single-core giant, the 12900KF. This translates to around a 3.5% performance improvement.
Multi-thread performance

As you can see from these benchmarks, the prospective 13900K scored 13,054 points in CPU-Z’s multi-thread benchmark. This is only marginally above the Ryzen 9 5950X, which scored 11,841 points. This roughly translates to a performance improvement of 10%.
Considering the 5950X is two whole generations behind the 13900K, so will 10% be enough to stave off the Zen 4 flagship 7950X? Only time will tell.
A quick look at the suspected 13900K sample
This leak has given us a huge amount of information about the 13900K engineering sample. First off, we have to mention that this is an engineering sample, so everything you read here is good enough to serve as a baseline, but is of course subject to change.

First off let’s note the core frequency. The maximum frequency reported in this leak stands at 4987.8MHz, way lower than the 12900KS or even the baseline 12900K. We think this will be a dialed-back frequency to focus on stability, and the real frequency will run around 5.5GHz, similar to the 12900KS.
This 13900K sample is hot stuff, literally. The reported maximum temperature reads 100°C or 212°F. We just hope that this reading wasn’t taken with any form of adequate cooling, because if the 13900K runs this hot with an AIO, we can’t see it doing too well on the market.
Another reading to take note of is the voltage. We’d expect to see voltages in the 1.35V region as this is what we’re used to. But the voltage read-out for the 13900K reads 1.476V way over the 12900K’s recommended max reading of 1.275V.
However, we know the 12900KS has a voltage range of 0.7V to 1.43V, so maybe near 1.5V readouts are going to be the new norm. No wonder the chip runs so hot. Yet the 13900k retains a supposed 125W TDP.
The supposed 13900K has 6MB more cache than the 12900KS, totaling 36MB of L3 Cache. With 8 x 48 KB (12-way, 64-byte line) + 16 x 32 KB (8-way, 64-byte line) L1 data Cache and 8 x 32 KB (8-way, 64-byte line) + 16 x 64 KB (8-way, 64-byte line) L2 Cache.
Final word
Although the 13900K is supposed to be a minor improvement on the 12900KS, it’s still an improvement, and the technology involved is impressive. Intel has made leaps and bounds in the CPU industry and with products like this, it’s easy to see why. we hope you enjoyed our i9-13900K appears on CPU-Z Validator article.
