VS

GeForce GTX 950 vs GeForce GTX 970M

Intro

The GeForce GTX 950 makes use of a 28 nm design. nVidia has set the core frequency at 1024 MHz. The GDDR5 RAM runs at a frequency of 1652 MHz on this particular card. It features 768 SPUs along with 48 Texture Address Units and 32 Rasterization Operator Units.

Compare all that to the GeForce GTX 970M, which features a clock frequency of 924 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 192-bit memory bus, and makes use of a 28 nm design. It is made up of 1280 SPUs, 80 TAUs, and 48 ROPs.

GeForce GTX 970M 96000 MB/sec
Difference: 9728 (10%)

Texel Rate

The GeForce GTX 970M is a lot (about 50%) faster with regards to AF than the GeForce GTX 950. (explain)

GeForce GTX 970M 73920 Mtexels/sec
GeForce GTX 950 49152 Mtexels/sec
Difference: 24768 (50%)

Pixel Rate

The GeForce GTX 970M will be a lot (approximately 35%) better at FSAA than the GeForce GTX 950, and also should be capable of handling higher screen resolutions better. (explain)

GeForce GTX 970M 44352 Mpixels/sec
GeForce GTX 950 32768 Mpixels/sec
Difference: 11584 (35%)

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: Bandwidth is the largest amount of data (in units of MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
