DDR numbers

[RyomaSJibenG]

this is actually more of a general question than a graphic card question but i kinda need to clarify this because its confusing to me

why the numbers different for RAM and GPU?

lets take an example of my build|

mobo: MSI Z97 Gaming 5
RAM: Kingston 8GB DDR3
GPU: MSI GTX960 DDR5

why are GPU use 5 and RAM 3?

 

once a person ask me this, i can't answer it....so yea just for knowledge

The GPU uses graphics optimized RAM and it is the 5th revision. Your MOBO uses 3rd revision. GDDR5 = Graphics Double Data Rate 5.

There are two GDDR revisions based on DDR2 and two more based on DDR3. So it's two numbers ahead.

The name in the motherboard memory is DDR3. The on-board memory for video cards today are called GDDR5 memory, similar to DDR3 memory but used on video cards for dedicated video card usage.

[Zweihander]

GDDR5, and DDR3 are two seperate forms of memory. Both fundamentally set up for the application utlizing either form.

 

GDDR5 is graphics-based memory, while DDR3 refers to standard, non-graphics RAM.

so basically its 2 different systems, the ones use for GPU is GDDR which specializes for graphics while RAM use normal(?) DDR for system's task

and for some reason it seems that GPU is a little bit ahead from the RAM which someway somehow compatible to each other

VRAM for graphics cards are ways ahead of system RAM.

We are already reaching maxmium speed of GDDR5 VRAM on graphics cards (most are rated at 7GHz...exactly what NVidia has them running at).

AMD and NVidia are already moving to 3D stack memory for graphics card -- HBM comes to mind?

Though AMD gets first dips since they helped Hynix design them...
