There are competing memory standards in the graphics industry, including GDDR5, GDDR5X, and high bandwidth memory (HBM) solutions. What will tomorrow bring? If you ask Micron, the memory with roots in Boise, Idaho will tell you that it has a roadmap in place for faster GDDR5X memory and is also working on next-generation GDDR6 memory chips. For geeks like us, it has been interesting to observe the evolving graphics memory standards. For a moment in time, it looked like HBM (and now HBM2) chips were the future, but Micron proved that GDDR still had legs when it announced in 2015 that it was developing... Read more...
Eventually we're going to see next-generation graphics cards outfitted with GDDR5X memory. It's a process getting to that point, and slowly but surely, things are moving along. To wit, JEDEC ratified the GDDR5X specification back in January of this year, and not even a full month later Micron announced that its GDDR5X program was in "full swing" with sampling to soon follow. Well, that time has come.We just got word straight from Micron that it has indeed started sampling GDDR5X memory to clients. That's a big deal because it's one of the last steps in the rather long process of introducing new... Read more...
We have been hearing about the next iteration of DDR for graphics for the past handful of months, and now, the folks at JEDEC have made it official. Called GDDR5X (the full standard is called JESD232 GDDDR5X SGRAM), this memory is designed to be twice as fast as GDDR5 per clock, boasting total throughput rates of 14Gb/s per pin. With GDDR5, peak bandwidth was 8Gb/s, which required the memory to be run at 2GHz. NVIDIA's current top-end cards peak at 7Gb/s, with clock speeds of 1.75GHz. With GDDR5X, we can see performance of 10Gb/s - 2Gb/s better than the previous max - at 1.25GHz. That's 70%... Read more...
