That would still not match the ps4's performance. You simply cant build anything with 8gb DDR5 dedicated to graphics.

You're under the assumption the PC needs 8gb of GDDR5 on the graphics chip.
Remember, it's only Ram, it doesn't do *any* form of processing itself.
In the PC world it's essentially another level of cache that can hide the bandwidth and latency hit of using System memory (Which PC GPU's can also use.)

By your logic, because I don't have 8gb of GDDR5 of system memory, my PC by default is slower than the PS4, which is laughable.

Besides, the PS4 doesn't even have all 8Gb dedicated to graphics tasks anyway, 1Gb is reserved for the OS, that drops it down to 7Gb, the rest of the 7Gb is certainly not going to be dedicated to the GPU, a massive chunk... Sure.
