GeForce GTS 250 1GB vs GeForce GTX 950

Intro

The GeForce GTS 250 1GB makes use of a 65/55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 memory is set to run at a speed of 1100 MHz on this particular card. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.

Compare those specs to the GeForce GTX 950, which has GPU core speed of 1024 MHz, and 2048 MB of GDDR5 RAM set to run at 1652 MHz through a 128-bit bus. It also is comprised of 768 SPUs, 48 TAUs, and 32 Raster Operation Units.

GeForce GTS 250 1GB 70400 MB/sec
Difference: 35328 (50%)

Texel Rate

The GeForce GTX 950 will be a bit (more or less 4%) better at anisotropic filtering than the GeForce GTS 250 1GB. (explain)

GeForce GTX 950 49152 Mtexels/sec
GeForce GTS 250 1GB 47232 Mtexels/sec
Difference: 1920 (4%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 950 is superior to the GeForce GTS 250 1GB, and very much so. (explain)

GeForce GTX 950 32768 Mpixels/sec
GeForce GTS 250 1GB 11808 Mpixels/sec
Difference: 20960 (178%)

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 data (in units of MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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