Graphics DRAM is a category of DDR SDRAM chips made to specifically handle the enormous demands of graphics processing. Unlike standard DRAM, graphics DRAM is a fixed and dedicated memory, generally combined with the graphics processing unit (GPU) – either on the graphics card or on the system board (for systems with onboard graphics). Graphics DRAM also helps shift the display and graphics-related load away from the computer’s main memory, as well as improve the performance of the GPU and the system’s display.
GDDR5 is not a direct replacement to GDDR3 due to package size differences:
- GDDR3: BGA-136
- GDDR5: BGA-170
