Suspected Intel i9-13900K appears on CPU-Z Validator

Last updated:

i9-13900K is displayed on the CPU-Z Validator: A technical selection of the suspected i9-13900k was validated by the CPU-Z validator on July 20th. We do not know who submitted the results, as the name of the publishing system just reads DESKTOP-4BR4UIF. So it could really be anyone, from Intel itself, to a third-party early tester.

Read now: Intel 13th generation, as far as we know.

This leak is a goldmine of information, and it also confirms rumors that Intel’s 13th gen will also support DDR4 RAM, as we covered in this Gigabyte motherboard article.

The leak

The leak was revealed by the exact leak @TUM_APISAK post about it on their Twitter account. Here is the original post on the CPU-Z Validator website.


In this post on CPU-Z’s website, we can see that the suspected 13900K technology test has received some performance figures, as well as some new and exciting information about the operation.

Simple core performance

single core 13900k

As you can see, the suspected 13900k engineering test scored a very respectable one 846 points and CPU-Zs benchmark. This is a full 27 points ahead of the previous generation’s single-core giant, 12900KF. This translates to around a 3.5% performance improvement.

Multi-thread performance

As you can see from these references, the potential 13900K received 13,054 points in the CPU-Z’s multi-threaded reference. This is only marginally above the Ryzen 9 5950X, which received 11,841 points. This can be roughly translated to one performance improvement of 10%.

Considering that the 5950X is two whole generations behind the 13900K, will 10% be enough to ward 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 test. First of all, we must mention that this is an engineering test, so everything you read here is good enough to serve as a baseline, but can of course be changed.

statistics little

Let us first note the core frequency. Maximum frequency reported in this leak is on 4987.8 MHz, much lower than 12900KS or even the baseline 12900K. We believe this will be a callback frequency to focus on stability, and the real frequency will run around 5.5 GHz, equivalent to 12900KS.

This 13900K sample is literally hot stuff. The reported maximum temperature shows 100°C or 212°F. We just hope that this reading was not taken with any kind of adequate cooling, because if 13900K runs so hot with an AIO, we can not see that it does so well on the market.

Another reading to note is the excitement. We expect to see voltages in the 1.35V region, as this is what we are used to. But the voltage reading for 13900K reads 1.476V well above 12900Ks recommended maximum reading of 1,275V.

However, we know that 12900KS has a voltage range of 0.7V to 1.43V, so maybe close to 1.5V readings are going to be the new norm. No wonder the piece gets so hot. Still, 13900k retains an estimated 125W TDP.

The supposed 13900K has 6MB more cache than 12900KS, a total of 36MB L3 Cache. With 8 x 48 KB (12-way, 64-byte line) + 16 x 32 KB (8-way, 64-byte line) L1 data buffer and 8 x 32 KB (8-way, 64-byte line) + 16 x 64 KB (8-way, 64-byte line) L2 Cache.

Last word

Although the 13900K is meant to be a minor improvement over the 12900KS, it is still an improvement and the technology involved is impressive. Intel has taken steps and boundaries in the CPU industry, and with products like this, it’s easy to see why. we hope you enjoyed our i9-13900K display on the CPU-Z Validator article.

Stay tuned for more news from the 13th generation Raptor Lake.
