The Inquirer writes AMD expects that GDDR5 memory will be used as part of its chip memory hierarchy, as prices come down.
AMD has long been promoting its idea of unified memory access where the CPU and GPU both have access to main memory. What the firm is now looking towards is making that main memory comprised of both types of DRAM, that is, both DDR memory and significantly higher bandwidth GDDR memory.
John Gustafson, chief graphics product architect at AMD told The INQUIRER that firms have been looking to increase bandwidth between the CPU and system memory but the price has been prohibitive.
He said, "Everybody is looking to use that extra speed memory in combination with the lower cost memory, just like you do with all memory tiers. It's a new tier of memory. A long time ago in HPC you always wanted to have static RAM right next to the processors and the DRAM far away and we're back to that situation again."
