GeForce GT 755M SLI Game Requirement Analysis
GeForce GT 755M SLI is a solution of two GeForce GT 755M put together using NVIDIA's SLI technology.
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.
Each GPU accesses a 2GB frame buffer of fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1350MHz.
Power Consumption lies between 75W and 125W.
Because SLI Relies on Proper Driver Support for Scaling, Performance may vary from game to game.
Overall, GeForce GT 755M SLI should offer Performance Comparable to a single GeForce GTX 770M at 1920x1080.
GeForce GT 755M SLI is best suited for resolutions up to and including 1920x1080.
