GeForce GT 1030 vs GeForce GTS 450 1GB

Intro

The GeForce GT 1030 features a GPU clock speed of 1265 MHz, and the 2048 MB of GDDR5 RAM runs at 1502 MHz through a 64-bit bus. It also features 384 SPUs, 32 TAUs, and 16 Raster Operation Units.

Compare those specs to the GeForce GTS 450 1GB, which features a GPU core clock speed of 783 MHz, and 1024 MB of GDDR5 memory set to run at 902 MHz through a 128-bit bus. It also features 192 Stream Processors, 32 TAUs, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at 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 video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
