AMD Radeon R7 M340 vs NVIDIA GeForce GTX 1070 Ti (Desktop) vs NVIDIA GeForce GTX 1080 SLI (Laptop)

AMD Radeon R7 M340

The AMD Radeon R7 M340 is a low-end dedicated graphics card for laptops. It could be based on a new derivative of the Tonga chip and therefore support DirectX 12, Vulkan and FreeSync. According to our informations the chip will be clocked at 1021 MHz and featuring 5 compute cores. That would turn out to be slower than the R5 M335 and M330 (but faster than the M320). The gaming performance should be therefore somewhere in the ballpark of the old Radeon R5 M255 (see for gaming benchmarks).

NVIDIA GeForce GTX 1070 Ti (Desktop)

The Nvidia GeForce GTX 1070 Ti is the second fastest Pascal based graphics card in November 2017. It is a high-end desktop graphics card based on a cut down GP104 chip as the GTX 1080 and manufactured in 16 nm FinFET at TSMC. Compared to the GTX 1080, it uses the more available GDDR5 graphics memory, and compared to the GTX 1070 it offers more shaders (2432 versus 1920). More details on the Pascal architecture including all features and comparisons to Maxwell, can be found here.

The performance of the GTX 1070 Ti was in our tests right between the GTX 1070 and GTX 1080. However, the powerefficiency was worse than the GTX 1070 and near the GTX 1080. Nvidia also specifies the 1070 Ti and 1080 at 180W.

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.
