i was talking to a friend of mine recently and he wondered why if RAM is so cheap, we cant just use some of it to bolster the VRAM on our graphics cards (we likened it akin to ssd caching
)
the only thing i could think of is that GDDR might be a different speed to the RAM in which case it might be a pain to get working correctly
but then i thought:
- if DDR > GDDR then why dont we just use the RAM for your Graphics cards?
- If GDDR > DDR then why dont they use the better chips for RAM?
it was all a little confusing which is why im looking for a clear answer here
