A lot of details about GDDR6X memory have surfaced after someone at Micron forgot to have the tech team proofread a recent briefing, as the marketing department seemingly had no idea that a lot of the published details were about a product that hasn't even been officially announced yet.
A lot of sites, including Videocardz, managed to scoop up the entire document - and it's still worth a read for those who are interested. Here's what the tech brief revealed:
In Summer of 2020, Micron announced the next evolution of Ultra-Bandwidth Solutions in GDDR6X. Working closely with NVIDIA on their Ampere generation of graphics cards, Micron's 8Gb GDDR6X will deliver up to 21Gb/s (data rate per pin) in 2020. At 21Gb/s, a graphic card with 12pcs of GDDR6X will be able to break the 1TB/s of system bandwidth barrier! Micron's roadmap also highlights the potential for a 16Gb GDDR6X in 2021 with the ability to reach up to 24Gb/s. GDDR6X is powered by a revolutionary new PAM4 modulation technology for Ultra-Bandwidth Solutions. PAM4 has the potential to drive even more improvements in data rate.
The 1008 GB/s bandwidth will be the first time the 1TB/s limit has been broken. However, the RTX3090 will most likely use the GA102-300 GPU with 5248 CUDA cores. 21 Gbps memory modules with a 1 TB/s bandwidth is still a major upgrade, though, and we get to keep the 30xx designation we have got used to.
