GDDR and DDR

[panyan]

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

im waiting for graphics cards that have flat ram slots like a laptop that you can upgrade the vram

Aint gonna happen because of the way semiconductor package technology has moved on over the years...


...but you knew that anyway

yeah, but its nice to dream about 8GB or VRAM

This could get interesting. Just think, first upgradeable RAM, then upgradeable processor. Soon we'll have a full upgradable graphics computer within our computers!

graphics cards are getting so complex and power hungry, they may are more like a "daughter-board" than a "card"
