Smulyanski: On-die SRAM accelerators excel at LLM decode due to high bandwidth
“The SRA machine basically keeps the entire weight matrix in SRA memory on DAI, so the, you got a lot more bandwidth, right, because it's on chip, right, so you can access, you know bytes over cycles, right, the chip interconnect is also fast, you can go, like …”

Smulyanski: GPU throughput drops sharply at low concurrency due to kernel overheads
“The moment that you start basically going to lower concurrency because you want better interactivity and better latency, Right? The performance the throughput drops. And it drops very sharply because all of a sudden you have a lot of, like, smaller kernels, yo…”
