GeForce GT 1030 vs GeForce GT 340

Intro

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

Compare all that to the GeForce GT 340, which makes use of a 40 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR5 RAM works at a frequency of 850 MHz on this particular card. It features 96 SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. 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 fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
