In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 950M 2GB are significantly better than the Nvidia GeForce GT 650M Mac 1GB Edition.

The GTX 950M has a 14 MHz higher core clock speed and 8 more Texture Mapping Units than the GT 650M. This results in the GTX 950M providing 7.8 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 950M has a 14 MHz higher core clock speed than the GT 650M and the same number of Render Output Units. This results in the GTX 950M providing 0.2 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 950M was released over a year more recently than the GT 650M, and so the GTX 950M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GT 650M.

The GTX 950M has 1024 MB more video memory than the GT 650M, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GT 650M has superior memory performance.

The GT 650M has 0.3 GB/sec greater memory bandwidth than the GTX 950M, which means that the memory performance of the GT 650M is marginally better than the GTX 950M.

The GeForce GT 650M Mac 1GB Edition has 384 Shader Processing Units and the GeForce GTX 950M 2GB has 640. However, the actual shader performance of the GT 650M is 346 and the actual shader performance of the GTX 950M is 858. The GTX 950M having 512 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 950M delivers a noticeably smoother and more efficient experience when processing graphical data than the GT 650M.

The GeForce GT 650M Mac 1GB Edition requires 45 Watts to run and the GeForce GTX 950M 2GB requires 50 Watts. The GTX 950M requires 5 Watts more than the GT 650M to run. The difference is not significant enough for the GTX 950M to have a noticeably larger impact on your yearly electricity bills than the GT 650M.

GPU Mini Review

Mini ReviewOverview
GeForce GT 650M Mac 1GB Edition is a Fast-Middle-Class Mobile Graphics Card based on the first revision of the Kepler Architecture.

Architecture
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.

GPU
It equips a GPU Codenamed GK107 which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 900MHz.

Memory
The GPU accesses a 1GB frame buffer of fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1254MHz.

Power Consumption
With a rated board TDP of 45W, it is suited for average sized laptops.

Performance
Gaming benchmarks indicate its performance is similar to GeForce GTX 660M.

System Suggestions
We recommend a decent processor and 8GB of RAM for a system with GeForce GT 650M Mac 1GB Edition.
Overview
GeForce GTX 950M 2GB is a Performance Mobile Graphics Card based on the first variant of the Maxwell architecture.

Architecture
The first variant of the Maxwell Architecture succeeds the Kepler Architecture. Despite being also manufactured with a 28nm technology, it has an extremely large L2 Cache which allows NVIDIA to produce Graphics Cards with relatively small memory data transfer rates, without causing too much impact on the overall performance. Furthermore, the Shaders have been redesigned and are both more powerful and energy efficient.

GPU
It equips a GPU codenamed GM107-N16P-GT which has 5 SM activated and thus offers 640 Shader Processing Units, 40 TMUs and 16 ROPs. The central unit runs at 914MHz and goes up to 993MHz, in Turbo Mode.

Memory
The GPU accesses a 2GB frame buffer of fast GDDR5, through a 128-bit memory interface. The memory clock operates at 1253MHz. The size of the frame buffer is adequate.

Features
DirectX 12 Support (11.0 Hardware Default) and support for GameStream, G-SYNC, GPU Boost 2.0, GeForce Experience, PhysX and other technologies.

Power Consumption
With a rated board TDP of 50W, it may be equipped in average sized notebooks.

Performance
Because GeForce GTX 950M 2GB is just a higher clocked GeForce GTX 850M v2 2GB, its performance is only about 5% faster than its predecessors and so GeForce GTX 860M 2GB is still faster.
Still, it still offers decent gaming at 1920x1080 and most modern games should run fluently at high settings.

System Suggestions
We recommend a strong processor (Intel Core i5 Mobile) and 8GB of RAM for a notebook with GeForce GTX 950M 2GB.
