BTW: it’s APU, without the G. Because it is an Accellerated Processing Unit 
(i.e. a processor), not a GPU.

Twice the single-thread performance and 7 times multi-core:

https://www.cpubenchmark.net/cpu.php?cpu=AMD+Ryzen+9+5900X&id=3870
Naturally at lower power consumption as well.

Well they allow you to put larger cards in, but they don’t have the lanes 
for it. Somewhere else in the thread was mentioned that the number of lanes 
is very limited. Only the main slot (the big one for the GPU) is directly 
connected to the CPU. The rest is hooked up to the chipset which itself is 
connected to the CPU either via PCIe×4 (AMD) or whatchacallit (DMI?) for 
Intel.

The 5900X has no built-in. For the Ryzen 5000 series, only those with -G 
have graphics. The 7000 ones all have a basic GPU (may except for some with 
another suffix).

Look for youself and filter what you need, like 1 or 2 HDMI, DP and PCIe:
AM4: https://skinflint.co.uk/?cat=mbam4&xf=18869_4%7E4400_ATX
AM5: https://skinflint.co.uk/?cat=mbam5&xf=18869_4%7E4400_ATX
Interestingly: the filter goes up to 6 PCIe slots for the former, but only to 
4 for the latter.
