GeForce GTX 1050 Ti vs Radeon HD 4890 1GB

Intro

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

Compare those specifications to the Radeon HD 4890 1GB, which makes use of a 55 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 memory works at a frequency of 975 MHz on this specific card. It features 800(160x5) SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
