Comparison between AMD Ryzen 9 7900 and Intel i9 13900k


The Battle of the Top end CPU's AMD vs Intel


When it comes to building a high-performance computer in the UK, choosing the right processor is crucial. Two popular processors in the market are the AMD Ryzen 9 7900 and Intel i9 13900K. In this blog post, we will compare these two processors in terms of their specifications, performance, and price to help you make an informed decision.


The AMD Ryzen 9 7900 is a 12-core processor with 24 threads, a base clock speed of 3.0 GHz, and a boost clock speed of 4.6 GHz. It has a thermal design power (TDP) of 280 watts and supports PCIe 4.0, DDR4 memory, and a maximum of 128 PCIe 4.0 lanes.

On the other hand, the Intel i9 13900K is an 8-core processor with 16 threads. It has a base clock speed of 3.5 GHz and a boost clock speed of 5.2 GHz. It has a TDP of 125 watts and supports PCIe 5.0, DDR5 memory, and a maximum of 20 PCIe 5.0 lanes.


In terms of single-core performance, the Intel i9 13900K performs slightly better than the AMD Ryzen 9 7900. However, the Ryzen 9 7900 outperforms the i9 13900K in multi-core performance, thanks to its additional cores and threads. The Ryzen 9 7900 also has a larger cache size than the i9 13900K, which can provide a significant boost in certain applications.


The AMD Ryzen 9 7900 is priced at around £530, while the Intel i9 13900K is priced at around £510. While the Ryzen 9 7900 is more expensive, it does offer better multi-core performance, which can be beneficial for tasks such as video editing or 3D rendering.

The Ryzen 9 7900 is a nice CPU, but it doesn’t make much sense for gamers. You’re much better off with the single CCD Ryzen 7 parts, and for productivity you might as well get the 7950X, or 13900K, though power usage and thermal issues make the Core i9 a lot less practical as a productivity CPU.

AMD could see its processor sales take off again with the arrival of this series of non-X Ryzen 7000 processors. They have many advantages, starting with a reduced power consumption compared to their big brothers 7000X. Of course, the performance is lower because of the lower frequencies, but thanks to their identical characteristics in terms of cores/threads and overclocking, it is quite possible to achieve performance close to that of the X version while having bought the processor for a more affordable price! One thing is for sure, we’ll be talking about these processors and particularly the Ryzen 5 7600 in the weeks to come.

We prefer the 65W processor’s low power requirements and thermal output far better; performance wise the 65W parts hold up well. Interestingly enough, the 12-core parts are a preferred buy by consumers, as that is what we hear back from the industry. 12-core parts outsold the 8-core part. Purely looking at what your average PC user needs, the 8-core part is fine, but for that little extra and at 36 USD per core the 12-core part can offer substantial value.


Both the AMD Ryzen 9 7900 and the Intel i9 13900K are high-performance processors that can handle demanding tasks. If you require better multi-core performance, the Ryzen 9 7900 might be a better choice. However, if you are more concerned about single-core performance and do not require as many cores, the Intel i9 13900K might be a better option. Ultimately, the choice between these two processors depends on your specific needs and budget.
