GeForce GT 315 vs GeForce GT 450 (OEM)

Intro

The GeForce GT 315 comes with a clock speed of 625 MHz and a DDR3 memory frequency of 790 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It features 48 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare those specifications to the GeForce GT 450 (OEM), which comes with a clock speed of 790 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 192-bit bus, and makes use of a 40 nm design. It is comprised of 144 SPUs, 24 Texture Address Units, and 24 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
