NVIDIA GeForce MX250 vs NVIDIA GeForce GTX 1080 SLI (Laptop)

NVIDIA GeForce MX250

The Nvidia GeForce MX250 is a dedicated entry-level mobile graphics card for laptops. It is based on the same Pascal GP108 chip as the predecessor, the GeForce MX150 / desktop GeForce GT 1030 but features increased clock speeds. As with the MX150, the MX250 is available in two versions, the normal 25 Watt version (1D13 device ID) and a low power version with 10 Watt TDP (1D25 device ID) and reduced performance (The MX150 with 10W had a 32% lower clock speed). The GDDR5 memory interface now also supports speeds up to 3.5 GHz = 7 GHz effective (up from 3 GHz).

The GP108 chip is manufactured in a 14 nm FinFET process at Samsung (LPP) and offers a number of new features, including support for DisplayPort 1.4 (ready), HDMI 2.0b, HDR and improved H.265 video de- and encoding (PlayReady 3.0). 4K HDR with Netflix however wont run due to the minimum 3 GB graphics memory that is required. Compared to the bigger Pascal chips, the small GP108 does not support Simultaneous Multi-Projection (SMP) for VR and G-Sync. A full list of improvements and the new Pascal desktop GPUs is available in our dedicated Pascal architecture article.

Thanks to the increased core speeds (up to +3% in Boost for the 25 Watt version, and faster memory speeds), the new MX250 should be slightly faster than the older MX150. First benchmarks indicate a 5% increase. Still modern should only run fluent in low settings (see the page of the MX150 for games and benchmarks).

NVIDIA GeForce GTX 1080 SLI (Laptop)

The Nvidia GeForce GTX 1080 SLI for laptops is a combination of two GTX 1080 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 1080 to up to 90% faster performance. Sometimes, the combination may also suffer from micro-stuttering. The technical details of the card are identical to a single GTX 1080 (see for more information) and the power consumption is doubled. Therefore, the 1080 SLI combination is only found in huge clunky laptops.
