It has equal fill rate. But only 25.6 GB/s of BW (will scale up when LPDDR4 matures to ~34 GB/s). That's not even half of the BW of the main memory and there's no alternative for the 32 MB ESRAM. The raw FP32 rate is also under under half of the console (FP16 rate is closer to the FP32 rate of Xbox One, but not there yet). A two SMX version could be competetive against the consoles if (and only if) they solved the bandwidth issue.Last but not least: did I misread something or did Jensen really claim that X1 has the performance of the Xbox One console? I call for bullshit no matter how much tear and feathers are on their way
They need to roughly 4x the memory controller width and wait for 2133 MHz LPDDR4. That would get them to 136.5 GB/s. Maxwell is more BW friendly than GCN (as it has delta color compression and bigger caches) so this should be enough. I don't actually even know the cache size of the Tegra Maxwell designs (2 MB L2 sounds a little bit high for such a small GPU, but not if you compare it to Intel designs).
