GeForce GTX 260 Core 216 vs GeForce GTX 650

Intro

The GeForce GTX 260 Core 216 uses a 65 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 memory is set to run at a frequency of 999 MHz on this specific card. It features 216 SPUs along with 72 Texture Address Units and 28 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 650, which comes with a GPU core clock speed of 1058 MHz, and 1024 MB of GDDR5 memory running at 1250 MHz through a 128-bit bus. It also is made up of 384 Stream Processors, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 64 Watts
GeForce GTX 260 Core 216 202 Watts
Difference: 138 Watts (216%)

Memory Bandwidth

The GeForce GTX 260 Core 216 should theoretically be quite a bit faster than the GeForce GTX 650 overall. (explain)

GeForce GTX 260 Core 216 111888 MB/sec
GeForce GTX 650 80000 MB/sec
Difference: 31888 (40%)

Texel Rate

The GeForce GTX 260 Core 216 will be much (approximately 22%) better at AF than the GeForce GTX 650. (explain)

GeForce GTX 260 Core 216 41472 Mtexels/sec
GeForce GTX 650 33856 Mtexels/sec
Difference: 7616 (22%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 650 is a better choice, though not by far. (explain)

GeForce GTX 650 16928 Mpixels/sec
GeForce GTX 260 Core 216 16128 Mpixels/sec
Difference: 800 (5%)

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 maximum amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 can be applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines 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 rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
