Wow. That does seem to require a crazy 512-bit wide bus though. The info I can find on HMC seems like it is achieving these speeds on a 16-bit bus and with much lower power requirements than even DDR3 so far.
- m_mueller 14y agoOk now that's new to me. If you can go 320GB/s on a measly 16bit bus, then it's really feasible to have this as your main memory. On the other hand imagine what you can do with this memory on a GPU, you'd probably get over 1TB/s there. Actually, that's something NVIDIA already has on their roadmap as far as I remember seeing it at GTC.
- ippisl 14y agoIn the spec they talk about 8-links each is 16 bit(or lanes in their jargon) , which comes out to 128 bit (or 256 bit - there are some configurations where input and output bits are on different pins).
