GeForce GT 1030 vs Radeon HD 3870 512MB

Intro

The GeForce GT 1030 features a GPU core speed of 1265 MHz, and the 2048 MB of GDDR5 memory is set to run at 1502 MHz through a 64-bit bus. It also is comprised of 384 Stream Processors, 32 Texture Address Units, and 16 ROPs.

Compare all that to the Radeon HD 3870 512MB, which has a clock speed of 775 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 256-bit memory bus, and uses a 55 nm design. It is made up of 320(64x5) SPUs, 16 TAUs, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total 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 applied in one second.

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