Its more power efficient than GDDRX, but not necessarily far from LPDDRX.
As a they speculated, a compromise seems like the future. Like a wider memory standard with stricter trace requirements, but not wide enough to require an interposer + control chip.
Or maybe just external memory controller/cache chips like the 7900 XTX, where the chip space for all the pins is less of a concern.
- sroussey 3y agoI’m a chiplet future, won’t an interposer likely exist anyhow?
- brucethemoose2 3y agoNot necessarily. There are different kinds if multi chip interconnects (with the fabs introducing more and more over the years), and leaving out HBM potentially allows for a cheaper interconnect over a smaller area.
