3Dxpoint is essentially a faster flash with all the problems of NAND cells. Its not memory-like with limited write endurance.
>While Intel claims the new non-volatile storage medium will offer significant improvements in endurance, performance, and power consumption (10x lower latency, 3x write endurance, 4x more writes per second, and as little as 30% the power consumption as competing NAND flash)

>3D XPoint memory has better endurance than NAND flash, but not enough to get away without wear levelling

- lodi 9y agoIt's "memory-like" because it's byte-addressable. Flash forces you to read a whole page to read a single byte.
- FrozenVoid 9y agoNormal RAM also forces you to read the page to L1/L2 cache. Is RAM not byte-addressable? See https://en.wikipedia.org/wiki/Cache_prefetching https://en.wikipedia.org/wiki/Cache_prefetching
