NVIDIA Maxwell GPU Surface Book vs NVIDIA GeForce 920MX

NVIDIA Maxwell GPU Surface Book

The Nvidia Maxwell GPU is a dedicated graphics card in the Microsoft Surface Book laptop. It is based on the Maxwell GM108 chip as the Geforce 940M with 384 shaders. Instead of the DDR3 graphics memory, the Surface Book graphics card features faster GDDR5 memory (both 64 Bit though).

Thanks to the faster graphics memory, the Surface Book Geforce is performing better than the average GeForce 940M. However, the 945M and GTX 950M are still noticeably faster. Demanding games therefore only run in low settings fluently.

More details can be found in our extensive review of the 2015 Microsoft Surface Book with the dedicated Maxwell GPU.

NVIDIA GeForce 920MX

► remove from comparison

The Nvidia GeForce 920MX is an entry-level graphics card for laptops that was launched in the first quarter of 2016. In comparison to the older 920M, the 920MX is now be based on the modern Maxwell chip of the 930MX but with a reduced shader count of 265 (GM108). According to our sources the TDP of 5-12 Watt and the support for DDR3 and GDDR5 is also specified.

The performance depends on the used graphics memory. The DDR3 version was slightly slower than an average GeForce 930M in our tests (and definitely faster than the GeForce 920M). The GDDR5 version could therefore best the 930M slightly. However, both versions are not suited for demanding games of 2017. Less demanding games, like The Sims 4, should be playable in medium to high settings (see below for benchmarks).

Thanks to the low power consumption, the GeForce 920MX is also suited for thin and light laptops.
