GeForce GTS 250 1GB vs GeForce GTX 650
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 specific card. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the GeForce GTX 650, which uses a 28 nm design. nVidia has set the core speed at 1058 MHz. The GDDR5 RAM is set to run at a speed of 1250 MHz on this particular card. It features 384 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
