JEDEC rubber stamps the GDDR7 spec, mega bandwidth VRAM is on its way for next-gen GPUs

When it comes to graphics cards, a significant portion of their performance comes from the onboard VRAM. That memory not only has to store masses of data for rendering or compute, it also needs to be able to transfer data very rapidly. JEDEC, the semiconductor standards body, has finalised the specifications of GDDR7, the next generation of ultra-fast video RAM, with double the bandwidth of GDDR6.

News of the spec approval (via TechPowerUp) has been well received and for good reason, as it's not just the raw speed that's better. At the moment, if you want the fastest VRAM, you either buy 24Gbps GDDR6 from Samsung or 24Gbps GDDR6X from Micron (the only company to make that type of memory).
