Did Nvidia skip the 800 series for graphics cards?
GeForce 800M series
Nvidia has announced that the company skipped the GeForce 800 series for desktop graphics cards, most likely because the GTX 800M series consists of high-end Kepler and low-end Maxwell based components. Instead, Nvidia had announced that the newly renamed GeForce GTX 980 and GTX 970 will be introduced formally on September 19, 2014.
Qualcomm Snapdragon
Benchmark tests of the Snapdragon 800's processor by "PC Magazine" found that its processing power was comparable to similar products from Nvidia. Benchmarks of the Snapdragon 805 found that the Adreno 420 GPU resulted in a 40 percent improvement in graphics processing over the Adreno 330 in the Snapdragon 800, though there were only slight differences in processor benchmarks. Benchmarks of the Snapdragon 801 inside an HTC One found a "bump all around" in benchmark improvements over the 800. In 2015, Samsung's decision not to use the Snapdragon 810 in its Galaxy S6 had a significant detrimental impact on Snapdragon's revenues and reputation. Benchmark tests by Ars Technica confirmed rumors that the 810 under-performed lower-end models and had overheating issues. A Qualcomm spokesperson said these tests were done with early versions of the 810 that weren't ready for commercial use. An updated version was released and was found to moderately improve thermal throttling, GPU clock speeds, memory latency, and memory bandwidth when tested in a commercial product, the Xiaomi Mi Note Pro. Additionally, the 820/821, 835 and 845 performed substantially better. Since the 820 Qualcomm lead the industry in sustained GPU performance and perf/W until the release of the Apple A12. The 835 and 845 both outperformed and were more effificent than Samsung's Exynos 8895 and 9810.
