12 GB VRAM is the new 8 GB VRAM: youtube.com/watch?v=ric7yb1VaoA ("Gaming Laptops are in Trouble - VRAM Testing w/ @Hardwareunboxed") and here is a case, where even 12 GB VRAM are not enough: youtu.be/qPGDVh_cQb0?t=283 ("Worst 70 Series Ever, GeForce RTX 5070 Review"). AMD not going for a GDDR7 PHY and having the 3 GB density chips was a mistake (no memory dense workstation AI cards and now no memory dense laptop either). Now lightweight, non-bulky, 128-bit, gaming laptops with 12 GB VRAM exist and for now, they will all have a NGREEDIA GPU, while AMDone looks like a deer in headlights. Memory being so expensive and everyone wanting to cash-in on it is the big bummer, but those who have the means, will still get these 3 GB per GDDR7 chip memory density devices, especially companies.
Quotewarns that the new RTX 5070 could cost almost as much as the RTX 5070 Ti
Over time they should become cheaper and the higher price? Well, there are still many people who are ok with paying more for a thinner and lighter device with 12 GB VRAM (RTX 5070 Ti / 192-bit laptops are quite a bit bulkier, heavier, bigger/thicker, louder).
For everyone else, who doesn't understand what this news is about:
128-bit (5070 laptops)/32-bit per GDDR7 chip = 4 GDDR7 chips, each 2 GB = 8 GB VRAM (current).
192-bit (5070 Ti laptops)/32-bit per GDDR7 chip = 6 GDDR7 chips, each 2 GB = 12 GB VRAM (current).
128-bit (5070 laptops)/32-bit per GDDR7 chip = 4 GDDR7 chips, each 3 GB = 12 GB VRAM (
new now -- this news).
