… This slide, shown back in July, is actually outdated as far as performance is concerned, but accurately illustrates expected power consumption. Samsung claims it can drive 450MB/s of read performance and 250MB/s wite performance per watt of power consumption. …
… It's not clear how AMD would perform if we charted the Ryzen 5000 series on a similar graph, but x86 CPUs don't generally compare well to chips like Apple's M1 Pro and M1 Max right now when it comes to performance per watt. …
… Kal-El's ability to maximize potential performance per watt will depend on how accurately Nvidia has modeled various scenarios. …
… Even if we assume a tweaked Vega could move the needle say 10-15 percent in terms of overall performance, power efficiency, or performance-per-watt pick your criteria , it wouldn't make a major difference relative to whatever family Nvidia is likely to launch. …
… A 1.5x improvement in performance-per-watt over GCN is also substantial -- larger than the ~1.33x gains we saw for Radeon VII over Vega 64. …
… AMD says it has improved performance-per-watt by 54 percent over RDNA2, a stunning achievement. …
… While they're closely matched in performance, the GTX 1080 edges out Vega 64 in performance-per-dollar thanks to a lower base price tag and slightly higher results. Overall performance scaling as a function of price isn't very good. …
