I've found reference to 291 Mbit parts from Intel on their 32 nm process. No indication of die size for a real density comparison.

My main point though is even with a 1/6th reduction in density it would still be good enough. For example, a system supporting 192 GB max going to 32 GB max with better bandwidth and latency would be a good trade off for some applications.
