AMD rumored to use 'slow' 18Gbps GDDR6 in RDNA 4 — leaker says Team Red's next generation GPUs won't use GDDR7

GDDR6 may not have GDDR7's bandwidth, but that doesn't inherently mean RDNA 4 will be slow.

Ah I remember the old days when a ram generation lasted longer than two years.
- Yeah, the days of DDR3 and PCIe 3.0 seems like eternity.
  
  We'd be all hype when they managed to squeeze another hundred megahertz out of it.
  
  I’m still on PCIe 3. But that’s mostly because changing motherboards is a pain in the ass.
- GDDR6 debuted in 2018
Totally fine with me, I just want more vram, way more vram
- Same. Get me a card with an older chip that has 32/64 gigs of just-decent VRAM but they won't do it!
  
  128gb of gddr5! Lol
- Who needs texture compression or advanced streaming techniques when you can just have all 200GB of data in memory at once?
  
  For gaming, the improvement in cores matters much more than the memory bandwidth, and for machine learning, more memory is needed desperately, so a new core with more vram, even if it's not the latest hot shit vram, I would be totally happy with.
Whatever happened to HBM? I remember it being hyped as the next big thing in memory speeds (I think by AMD), but nobody seems to use it.
- iirc it's because it's a lot more expensive compared to normal gddr. It's still being used in the high end enterprise market.
- Also reliability, hbm2 cards seem to have a higher rate of dying
