NVIDIA GeForce GTX 1070 SLI (Laptop) vs NVIDIA GeForce GTX 1080 Ti (Desktop)

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.

NVIDIA GeForce GTX 1080 Ti (Desktop)

The Nvidia GeForce GTX 1080 Ti is the fastest desktop consumer graphics card (beginning 2017). It is based on the same GP107 chip as the Titan X but with slightly higher clock speeds and a different memory configuration. It offers one memory controller less (and 11 instead of 12 GB), but the GDDR5X memory is faster clocked (11 GHz) leading to a comparable memory bandwidth. Due to the higher boost clock, the 1080Ti should be around 5 % faster compared to the Pascal Titan X and about 35 % faster compared to the GTX 1080. The TDP is equal to the Titan X with 250 Watt. A new cooler of the Founders Edition should be more efficient and quieter.
