THE CELL "made sense" because it was something new and different from the normal tech. This is just RAM, only "a lot" of it.
I honestly don't know why some PS fans are using this as the new cell. It's kinda stupid imo.

It's DDR5 system ram, which is unheard of today except in graphics cards. There's no motherboard today that uses DDR5 ram modules for system ram (yet), which is twice as fast as DDR3 ram, so ya, it IS a big deal. It's not just the amount of ram, its the speed!

DDR5 doesn't exist yet. GDDR5 is a form of DDR3 optimized for graphics.
Two components of a computer need access to RAM - the GPU and the CPU. The GPU is bandwidth limited. Higher bandwidth = greater performance here, generally.
The CPU though is latency limited. This is why GDDR RAM is not used as system RAM. Most RAM on a PC goes to the CPU, only going to the GPU if there is not enough VRAM. GDDR5 has very high latency. It would not perform well at all.
People need to stop thinking higher numbers equals better solutions. Most of that 8GB won't be used anyway. Blu-ray has a read speed of somewhere around 20MB/s. What's 8192 / 20? It would take close to a 7 minute load in order to cache all of the data in RAM.
