It’s no secret that NVIDIA’s new GeForce RTX 3070 only uses GDDR6 memory (the faster, shinier GDDR6X is being reserved for the GeForce RTX 3090 and GeForce RTX 3080 flagships), but there’s been a bit of speculation as to how fast those chips actually are.

ASUS and ZOTAC appear to have the answer. According to updated specification pages for the ZOTAC GAMING GeForce RTX 3070 Twin Edge and ASUS Dual GeForce RTX 3070 (via TechPowerUp), the GeForce RTX 3070 uses older, slower 14 Gbps GDDR6. This mirrors the memory speeds of its preceding models (the GeForce RTX 2070 and GeForce RTX 2070 SUPER), but it falls short of the GeForce RTX 2080 SUPER’s 15.5 Gbps GDDR6.

We’re guessing that NVIDIA is saving that sweeter 16 Gbps GDDR6 for the inevitable GeForce RTX 3070 Ti/SUPER. Depending on how AMD’s mid-range RDNA 2 cards turn out, we may even get them sooner rather than later.

  1. I guess we’ll find out when it can only use 7.5G of the 8G installed.

    Always something with the x70’s

    If it makes up for it in raw compute power then it’s moot. Two ways to skin a cat.
    Except you can’t skin a cat well with a dull knife.

  3. Since this card is sitting ~2080 Ti perf level 14 Gbps should be fine. Seems pretty obvious now that NV is staging their super/refreshes based on what AMD is planning along with whatever deals they’ve got lined up with [URL=’’]Micron[/URL].
