GeForce GT 420 vs GeForce GTX 950M

Intro

The GeForce GT 420 comes with core clock speeds of 700 MHz on the GPU, and 900 MHz on the 2048 MB of GDDR3 memory. It features 48 SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Compare those specs to the GeForce GTX 950M, which features GPU core speed of 914 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 TAUs, and 16 ROPs.

GeForce GTX 950M 32000 MB/sec
GeForce GT 420 28800 MB/sec
Difference: 3200 (11%)

Texel Rate

The GeForce GTX 950M will be quite a bit (about 553%) better at AF than the GeForce GT 420. (explain)

GeForce GTX 950M 36560 Mtexels/sec
GeForce GT 420 5600 Mtexels/sec
Difference: 30960 (553%)

Pixel Rate

The GeForce GTX 950M will be much (more or less 422%) more effective at FSAA than the GeForce GT 420, and capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 950M 14624 Mpixels/sec
GeForce GT 420 2800 Mpixels/sec
Difference: 11824 (422%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
