The "3,854 cores" versus "28 cores" is dubious as always. 3,854 I think counts just the individual fp32 ALUs; a true similar comparison would be number of warp

The "3,854 cores" versus "28 cores" is dubious as always. 3,854 I think counts just the individual fp32 ALUs; a true similar comparison would be number of warp schedulers or maximum number of warps resident at once, or even just SM count (which share a cache). Apples to oranges (a super-hyperthreaded 1024/2048-bit wide vector machine with minimal cache to a minimally hyperthreaded 128/256-bit wide vector machine with lots of cache).
