GeForce GTX 550 Ti vs GeForce GTX 950

Intro

The GeForce GTX 550 Ti comes with core clock speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 RAM. It features 192 SPUs along with 32 TAUs and 24 ROPs.

Compare that to the GeForce GTX 950, which uses a 28 nm design. nVidia has clocked the core frequency at 1024 MHz. The GDDR5 memory is set to run at a frequency of 1652 MHz on this particular card. It features 768 SPUs along with 48 Texture Address Units and 32 ROPs.

Memory Bandwidth

Theoretically speaking, the GeForce GTX 950 should be 7% faster than the GeForce GTX 550 Ti in general, due to its greater bandwidth. (explain)

GeForce GTX 950 105728 MB/sec
GeForce GTX 550 Ti 98496 MB/sec
Difference: 7232 (7%)

Texel Rate

The GeForce GTX 950 should be quite a bit (approximately 71%) better at texture filtering than the GeForce GTX 550 Ti. (explain)

GeForce GTX 950 49152 Mtexels/sec
GeForce GTX 550 Ti 28800 Mtexels/sec
Difference: 20352 (71%)

Pixel Rate

The GeForce GTX 950 should be much (more or less 52%) faster with regards to anti-aliasing than the GeForce GTX 550 Ti, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 950 32768 Mpixels/sec
GeForce GTX 550 Ti 21600 Mpixels/sec
Difference: 11168 (52%)

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 maximum amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
