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

NVIDIA GeForce GTX 1080 Max-Q

The Nvidia GeForce GTX 1080 with the Max-Q design is a mobile high-end GPU from the Pascal series. It is designed for thin and light laptops and about 10-15% slower than a regular GTX 1080 for laptops based on the cooling capabilities. The base frequency (1101-1290 MHz) is also much lower than on the regular GTX 1080 (1566 MHz, at least -18%) and the Boost (1278-1458 MHz) is also much lower compared to 1733 MHz (at least -16%) for the regular GTX 1080. The memory clock, however, is identical.

The clock is not the only difference compared to the regular GTX 1080 though. The drivers for the Max-Q version were optimized for efficiency (and not performance; only for Max-Q models), there are optimized voltage converters for 1V operation, high-end cooling methods, and a 40 dB limit for the fan noise (with clock adjustments to ensure this at all times).

The performance is nearer to the normal (Max-P) GeForce GTX 1070 than to then GTX 1080 (at least in the Asus Zephyrus). Therefore, most demanding games should be playable in full HD and maximum detail settings (see game benchmarks below).

Features

The GP104 chip is manufactured in 16nm FinFET process at TSMC and offers a range of new features. DisplayPort 1.4 (ready), HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP), improved H.265 video en- and decoders (for PlayReady 3.0) are only some of the improvements. See our detailed Pascal architecture article for more details.

The power consumption of the Max-Q design is notably lower than the normal GTX 1080 for laptops and ranges between 90 and 110 Watt (TGP) according to Nvidia.

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.

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.
