Micron has announced that they will begin the mass production of its new high-speed memory GDDR5X in the summer, a new standard that replaced the already “obsolete” GDDR5 graphics memory and offer twice as fast compared to the current.
With this confirmation, we have bad news, because if its mass production will begin in the summer, it will not be implemented until winter so we will not see new Graphics cards from both AMD and NVIDIA side and launch of a first batch of GPUs with HBM2 memory will feature a high price while at the end of the current year and we could start to see the medium range graphics cards with GDDR5X memory.
In mid-2016 it is expected that AMD and NVIDIA make use of HBM2 memory, but later repeated releases with JESD232 Graphics Double Data Rate (GDDR5X memory) to settle much faster than the current graphics cards with lower price. JEDEC has already released the official specifications of GDDR5X, which revealed what we already knew, the GDDR5X memory is up to twice as fast as the current GDDR5 found in the current top-end high-end GPUs from NVIDIA or AMD (AMD’s top model used HBM1).
While the GDDR5 memory today has access to 32 bits that are saturated to 7 Gbps, the GDDR5X memory comes to solve it with access 64 bits allow the graphics cards to accomplish initially speeds of 10 or 14 Gbps, which translates to double its peak performance, but that’s not everything, since its maximum potential will be in the 16 Gbps, so there will be a range of further improvement too.
“GDDR5X represents a significant leap forward for high end GPU design,” said Mian Quddus, JEDEC Board of Directors Chairman. “Its performance improvements over the prior standard will help enable the next generation of graphics and other high-performance applications.”
The GDDR5X memory being touted as a very profitable memory compared with the next generation of HBM memory (HBM2). So, both AMD and NVIDIA will use this GDDR5 memory in low-mid-rage Graphics cards and book more expensive HBM2 memory for its top-end graphics, while GDDR5X come as a high performance solution at a lower cost, thus maintaining a strong performance at a competitive price.
