Why is it a concern ? What matters to you,m how it performs or what number is stamped on the chip ? Is there some application or game that you have that only runs on one or the other ?

Did you go tot he link I posted ? Clcik on the GPU and you will get the lowdown on each chip

The NVIDIA GeForce GT 740M is a DirectX 11 graphics card of the middle class. It is based on the Kepler architecture and manufactured by TSMC in a 28-nanometer process. In addition to an older version with the GK107 chip (384 shader, 810 - 895 MHz, 128 bit memory), there also exist models with the new GK208 (384 shader, up to 980 MHz plus boost, 64 bit memory). Both versions usually use DDR3 memory; however, GDDR5 versions are possible, too.

The NVIDIA GeForce GTX 850M is an upper mid-range, DirectX 11-compatible graphics card for laptops unveiled in March 2014. It is one of the first cards based on Nvidia's new Maxwell architecture (GM107 chip), but is still manufactured in 28 nm. The GTX 850M offers 640 shader units clocked at 876 MHz (+ Boost) as well as 2 GB of GDDR5 memory (128 bit, 5000 MHz effective). In addition, there is a slightly higher clocked version (936 MHz + Boost) using slower DDR3 memory (2000 MHz effective).
