GeForce GTS 250 1GB vs GeForce GTX 650

Intro

The GeForce GTS 250 1GB uses a 65/55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 RAM runs at a speed of 1100 MHz on this card. It features 128 SPUs as well as 64 Texture Address Units and 16 ROPs.

Compare those specs to the GeForce GTX 650, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1058 MHz. The GDDR5 memory runs at a frequency of 1250 MHz on this specific card. It features 384 SPUs as well as 32 TAUs and 16 ROPs.

GeForce GTS 250 1GB 70400 MB/sec
Difference: 9600 (14%)

Texel Rate

The GeForce GTS 250 1GB should be a lot (about 40%) more effective at anisotropic filtering than the GeForce GTX 650. (explain)

GeForce GTS 250 1GB 47232 Mtexels/sec
GeForce GTX 650 33856 Mtexels/sec
Difference: 13376 (40%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 650 is a better choice, by far. (explain)

GeForce GTX 650 16928 Mpixels/sec
GeForce GTS 250 1GB 11808 Mpixels/sec
Difference: 5120 (43%)

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 max amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock 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 in one second.

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