GeForce GT 1030 vs GeForce GTS 450 1GB

Intro

The GeForce GT 1030 makes use of a 16 nm design. nVidia has clocked the core speed at 1265 MHz. The GDDR5 RAM works at a frequency of 1502 MHz on this specific model. It features 384 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the GeForce GTS 450 1GB, which features GPU core speed of 783 MHz, and 1024 MB of GDDR5 RAM running 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 largest amount of information (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type 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 better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be 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 better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
