PC Graphics

Building a pc and new to AMD products, I was gonna pair the 7900XTX with Intel i7 13700K but a friend of mine recommended the 7800X3D instead with the promise of a buff on performance in addition to an AMD graphics card. Is this a good idea?

There isn't any special magic that make amd cpu and gpu combo perform better.

You might not think Infinity Cache might is special magic but why shouldn’t OP take advantage of RDNA 3.

I read the question differently, like is there some sort of boost pairing amd cpu and gpu, not which cpu is better.

I would definitely pair your 7900XTX with a 7800X3D! Take advantage of infinity cache and RDNA 3. I would also download AMD Adrenaline and make sure Smart Access Memory is enabled.

According to Tom's Hardware article comparing the Ryzen 7 7800X3D to Intel Core I7 13700K depends on what you are planning on using your PC that will determine which processor you want to use: https://www.tomshardware.com/news/amd-ryzen-7-7800x3d-vs-intel-core-i9-13900k-vs-intel-core-7-13700K

Is 13900K better than 7800X3D?

Overall, the 7800X3D will run faster and cooler than the 13900K in every gaming scenario, but the 13900K is far more potent in productivity-oriented tasks.Apr 13, 2023

AMD Ryzen 7 7800X3D vs Intel Core i9-13900K vs Core i7 .

The $448 Ryzen 7 7800X3D is now the fastest gaming CPU in the world. The 7800X3D recently debuted to critical acclaim, arriving with eight cores and 16 threads and AMD's Second-Gen 3D V-Cache that deliver ever-so-slightly more gaming performance than the flagship $699 Ryzen 9 7950X3D. The 3D V-Cache tech fuses a 3D-stacked cache chiplet atop the processor to deliver market-leading gaming performance at the expense of performance in productivity applications, but while it delivers explosive uplift in some games, not all titles benefit. 

Intel also has its Core i7-13700K, which offers nearly the same level of performance as the 13900K in gaming, but at a much more amenable $417 price point that is more competitive with the Ryzen 7 7800X3D. While the 13700K isn't as fast in productivity work as the 13900K, it also offers far more performance than the 7800X3D in the types of apps. 

Basically what the article is saying as quoted above if you want to use your PC mainly for gaming then install the AMD 7800X3D but if you are going to use your PC for mainly running Apps especially Professional type apps than you would install the Intel Core I7 13700K processor which is slight inferior to the AMD processor concerning gaming.

Your Friend is right AMD processors do work better with Radeon due to SAM!!!

Which is  the same thing as rebar.
