Micron reveals GDDR6X memory with up to 21 Gbps speeds
GDDR6X memory has been a long-rumoured addition to Nvidia’s Ampere gaming product line, offering significant increases to memory speeds over today’s GDDR6 modules. Now, Micron has officially confirmed the existence of GDDR6X and the speeds at which the new memory standard will operate at.Â
Videocardz was the first to report on this new memory type, linking to a paper which details the new memory standard. For starters, GDDR6X offers users more bandwidth per unit of power consumption, bringing the new memory standard relatively close to HBM2 memory. That said, newer HBM2E memory modules maintain their efficient advantage over GDDR-based memory types.Â

In the charge below, Micron has revealed that its GDDR6X memory modules will operate at speeds of between 19 Gbps and 21 Gbps, exceeding the capabilities of today’s fastest GDDR6 modules.Â
Right now, 14Gbps GDDR6 memory modules are common amongst most modern graphics cards, making Micron’s fastest GDDR6X modules 50% faster than today’s most common GDDR6 memory modules.Â
With a 384-bit memory bus on Micron’s “Example” RTX 3090 graphics card with a 12GB frame budder, memory bandwidth levels of 1008GB/s could be achieved. This bandwidth increase should surely meet the needs of Nvidia’s next-generation Ampere GPUs, easily outpacing the company’s RTX 2080 Ti. Â
 Â
With Micron calling its RTX 3090 listing an “example” application type, Nvidia’s RTX 3090 should not be considered the “confirmed” name of Nvidia’s upcoming gaming flagship. Neither should its 12GB frame buffer be considered a certainty.Â
Nvidia is due to reveal its next generation graphics hardware on September 1st, revealing what could be the company’s RTX 30 series of products.Â
