GeForce GTX 1050 Ti vs Radeon HD 4870 2GB

Intro

The GeForce GTX 1050 Ti features core clock speeds of 1290 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 768 SPUs along with 48 TAUs and 32 Rasterization Operator Units.

Compare those specifications to the Radeon HD 4870 2GB, which makes use of a 55 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 RAM is set to run at a frequency of 900 MHz on this card. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported 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 memory, it should be multiplied by 2 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

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