GDDR5X To Deliver Twice The Bandwidth Of GDDR5, Leaked Slides Suggest
Earlier, it was rumored that Nvidia was planning to use GDDR5X on their upcoming Pascal graphics cards, and now we have quite a few reasons we could see this happen.
A few presentation slides have surfaced online which reveal more details on upcoming GDDR5X memory standard. The slides claim that GDDR5X will deliver double the data-rate per memory access of 64 byte/access compared to 32 byte/access of the current GDDR5 standard.
The new standard will initially offer I/O data rates up to 10-12 GBbps with potential of achieving up to 16Gbps.
The leak also suggests that this won’t be limited to Nvidia only, but that AMD will also get on board and use this type of memory on some of their next-gen graphics cards.
GDDR5X will retain the same interface signal pin layout as GDDR5, that should make the upgrade relatively easy. Further, it will feature lower VDD and VDDQ for reduced power consumption.
