I know some apps are taking advantage of or utilizing graphics memory Thanks for any explanation. As far as I know, memories used on video cards have different characteristics than memories used on PC.. Just wait for other members with deeper knowledge that can give some information regarding of this matter.
Click to expand The GDDR5 setup also allows for doubling or asymetric memory configurations. GDDR handles input and output on the same cycle. The memory is also fundamentally set up specifically for the application it uses: System memory DDR3 benefits from low latency tight timings at the expense of bandwidth, GDDR5's case is the opposite.
The performance of a graphics card for instance is greatly affected as a percentage by altering the internal bandwidth, yet altering the external bandwidth the PCI-Express bus, say lowering from x16 to x8 or x4 lanes has a minimal effect. Sorry for the wall of text, but you did ask. Could you tell what are the pros and cons? I would really like to hear your opinion about that.
It is much faster than DDR PCs are everyday machines The use of GDDR5 is probably mandatory if you note the likelihood of increased complexity in the next generation console games higher polygon counts, more complex post process image quality. No problem It goes back to the nature of graphics rendering and how the polygons are drawn. Sorry if I'm teaching my grandmother to suck eggs, but it might be a little easier if I outline the graphics pipeline.
Up until this point you're basically dealing with CPU and RAM- executing and monitoring game code, creating resources, shader compile, draw calls and allocating access to the graphics since you likely have more than just the game needing resources. From here, the workload becomes hugely more parallel and moves to the graphics card.
Depending on what is called for, the output can be called to any part of the previous shader pipeline basically a loop or held in memory buffers. So basically, the parallel nature of graphics calls for input and output from vRAM at many points covering many concurrent streams of data. Some of that vRAM is also subdivided into memory buffers and caches to save data that would otherwise have to re-compiled for following frames. All this swapping out of data calls for high bandwidth, but latency can be lax saving power demand as any stall in one thread is generally lost in the sheer number of threads queued at any given time.
