Im planning my new config and one of the primary issue is that Im unsure whether 7950x3d is worth the hassle. If I went with 7950x, I would surely want to fiddle with overclocking.
As far as Im aware, 7950x3d can be overclocked, but only the one without the 3d cache. How reliable is this?
Also, I suspect that the TDP difference is a non-issue, as it is mostly just a limitation of the 7950x3d thermals rather than actually better power consumption.
Also the L3 cache is 64mb for the 7950x vs 128mb for 7950x3d. How much does that matter?
Things I want to do: gaming, software development, virtual machines, VR, AI related work. Im asking here since I mainly want to know about the status on linux.
The cache matters a lot. That's basically why the x3d chips are so great at gaming. With over clocking you'll always get a lower clock than the stock boost clock with these newer chips. That's why PBO (precision boost overdrive) in combination with CO (curve optimiser) will give the most performance. Both chips can do this.
Tl;Dr: get the x3d.
Shit. Forgot the price. What if I can get 7950x for like ~500 and the 7950x3d for like ~700?
I'd go for the 7800x3d if gaming is your priority. If you need the cores the 7950x would be the economical option.
