Intel HD Graphics 405 (Braswell) vs NVIDIA GeForce GTX 1070 SLI (Laptop)

Intel HD Graphics 405 (Braswell)

The Intel HD Graphics 405 (Braswell)  is an integrated graphics card in the low end SoCs of the Braswell series (e.g. Pentium N3710). It is based on the same architecture as the integrated GPU of the Broadwell graphics cards (e.g. HD Graphics 5300), but offers less shader cores and slower clock speeds.

The GPU was simply called Intel HD Graphics (Broadwell) before 2016 and included also the slower 12 EUs version in the Celeron model. The Graphics 405 name currently only stands for 16-core-versions in Pentium models. The 12 EU version is now called Intel HD Graphics 400.

The clock speed and memory configuration can still vary from model to model.

Gaming performance ist still only suited for older or less demanding games. Often also the processor is limited gaming performance (e.g. in the dual-core N3000).

The SoC also integrates a video decoding engine that should be able to handle 4K H.265 videos.

NVIDIA GeForce GTX 1070 SLI (Laptop)

The Nvidia GeForce GTX 1070 SLI for laptops is a combination of two GTX 1070 graphics cards in SLI mode. Each card renders one frame at a time (AFR mode) but depends for most games on a good profile in the driver. Therefore, the performance can range from no gains over a single GTX 1070 to up to 90% faster performance. In most games with SLI support, the GTX 1070 SLI is therefore faster than a single GTX 1080. However, sometimes the combination also suffers from micro-stuttering.

The technical details of the card are identical to a single GTX 1070 (see for more information) and the power consumption is doubled. Therefore, the 1070 SLI combination is only found in huge clunky laptops.
