GeForce GT 1030 vs GeForce GT 340 1GB

Intro

The GeForce GT 1030 features a core clock speed of 1265 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 64-bit bus, and makes use of a 16 nm design. It features 384 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Compare all of that to the GeForce GT 340 1GB, which uses a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 RAM is set to run at a frequency of 850 MHz on this card. It features 96 SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
