GeForce GTX 1050 3GB vs Radeon HD 3870 1GB

Intro

The GeForce GTX 1050 3GB has a GPU core speed of 1392 MHz, and the 3072 MB of GDDR5 memory is set to run at 1750 MHz through a 96-bit bus. It also features 768 Stream Processors, 48 Texture Address Units, and 24 ROPs.

Compare those specifications to the Radeon HD 3870 1GB, which makes use of a 55 nm design. AMD has set the core frequency at 775 MHz. The GDDR4 RAM is set to run at a frequency of 1125 MHz on this particular card. It features 320(64x5) SPUs as well as 16 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a 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 drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
