In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 555M are noticeably better than the Nvidia GeForce GT 550M 2GB.

The GT 550M has a 150 MHz higher core clock speed than the GeForce GT 555M, but the GeForce GT 555M has 8 more Texture Mapping Units than the GT 550M. As a result, the GeForce GT 555M exhibits a 2.4 GTexel/s better Texture Fill Rate than the GT 550M. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GT 550M has a 150 MHz higher core clock speed than the GeForce GT 555M, but the GeForce GT 555M has 12 more Render Output Units than the GT 550M. As a result, the GeForce GT 555M exhibits a 6.4 GPixel/s better Pixel Fill Rate than the GT 550M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GT 550M was released less than a year after the GeForce GT 555M, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GT 550M has 512 MB more video memory than the GeForce GT 555M, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GeForce GT 555M has superior memory performance.

The GeForce GT 555M has 14.4 GB/sec greater memory bandwidth than the GT 550M, which means that the memory performance of the GeForce GT 555M is slightly better than the GT 550M.

The GeForce GT 550M 2GB has 96 Shader Processing Units and the GeForce GT 555M has 144. However, the actual shader performance of the GT 550M is 142 and the actual shader performance of the GeForce GT 555M is 170. The GeForce GT 555M having 28 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 555M delivers a slightly smoother and more efficient experience when processing graphical data than the GT 550M.

The GeForce GT 550M 2GB requires 35 Watts to run and the GeForce GT 555M requires 35 Watts. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewOverview
GeForce GT 550M 2GB is a middle-class Mobile Graphics Card based on the first revision of the Fermi Architecture.

Architecture
The Fermi Architecture is manufactured with a 40nm technology and uses a technique known as Hot Clocking: The Shaders are clocked twice as fast as the Central Unit. While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.
Fermi is also the first GPU architecture with fully cached memory access which increases memory performance.

GPU
It equips a GPU Codenamed GF108 which has 2 Stream Multiprocessors activated and thus offers 96 Shader Processing Units, 16 TMUs and 4 ROPs. The Central Unit is clocked at 740MHz.

Memory
The GPU accesses a 2GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 900MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 35W, it is suited for 15" or larger laptops.

Performance
Gaming benchmarks put its performance only slightly above a desktop GeForce GT 430.

System Suggestions
We recommend a modest processor (Intel Core i3 Mobile) and 4GB of RAM for a system with GeForce GT 550M 2GB.

GPU
It equips a GPU Codenamed GF106 which has 3 Stream Multiprocessors activated and thus offers 144 Shader Processing Units, 24 TMUs and 16 ROPs. The Central Unit is clocked at 590MHz.

Memory
The GPU accesses a 1.5GB frame buffer of DDR3, through a 192-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 900MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 35W, it is suited for 15" or larger laptops.

Performance
GeForce GT 555M is a direct re-brand of GeForce GT 445M v2.
Gaming benchmarks put its performance only identical to a desktop GeForce GT 440 v3.

System Suggestions
We recommend a decent processor (Intel Core i5 Mobile) and 4GB of RAM for a system with GeForce GT 555M.
