GeForce GTX 460 (OEM) vs GeForce GTX 650
Intro
The GeForce GTX 460 (OEM) uses a 40 nm design. nVidia has set the core frequency at 650 MHz. The GDDR5 RAM runs at a frequency of 850 MHz on this model. It features 336 SPUs along with 56 TAUs and 32 ROPs.Compare that to the GeForce GTX 650, which makes use of a 28 nm design. nVidia has set the core speed at 1058 MHz. The GDDR5 memory runs at a frequency of 1250 MHz on this particular model. It features 384 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock 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 one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
