I don't know why there are so many people out there arguing against buying the 9800X3D. There seems to be this issue with 720/1080p benchmarks. They do understand that it is the CPU being benched and not the GPU?
Hardware Unboxed said it best:
People aren't only taking a dig at them, they are taking a dig at all reviewers which did these benchmarks at these resolutions. It is math.
Besides, who will now buy a 7800X3D when you can now buy a 9800X3D? It makes sense in the used market, but you won't get savings there either or at least not now. From how I see it, there are only two CPUs that serious gamers should consider, either the 5700X3D (whilst it lasts) and the 9800X3D. In my opinion, it is not worth saving the odd R1 000 by choosing the 7800X3D over the 9800X3D. Not given the current pricing. The 9800X3D is a massive improvement in benchmarks, hardware, and capability support.
Just bizarre. Either people have buyer's regret, have no one to speak to, hence needing attention, or are on someone's payroll, who knows?
There are circumstances where the 7800X3D should be considered, but all on AM5, it will likely boil down to availability, but where the 9800X3D becomes scarce due to demand, the 7800X3D won't become any cheaper either. Not to ignore that the 7800X3D is also becoming limited in availability. AM4 is still capable.
This whole argument is pointless anyway, all benchmarks conclude that the 9800X3D is the new gaming king irrespectively. Throw in next year's GPUs, and naysayers will have to eat their own current opinion.
