Internally, Logan’s GPU consists of a single Kepler SMX (the top-of-the-line GK110 in the GTX Titan uses 14 SMXes). There are probably some other changes to reduce power consumption, but it’s still essentially Kepler. Going by the graph below, which shows mobile Kepler to have five times the raw horsepower of the iPad 4′s SGX 554MP4 (77 gigaflops), we can infer that mobile Kepler will top out at 400 gigaflops – giving us peak theoretical performance that’s slightly better than the 8800 GTX (a seven-year-old chip) and significantly higher than the PS3. We have no idea of the clock speed or memory subsystem at this point, but we do know that a single Kepler SMX contains 192 CUDA cores — and as each core is good for two flops per cycle, that means mobile Kepler needs to be clocked at around 1GHz to hit 400 gigaflops.
