GeForce GTX 1050 vs Radeon HD 4890 2GB

Intro

The GeForce GTX 1050 comes with a GPU clock speed of 1354 MHz, and the 2048 MB of GDDR5 RAM runs at 1750 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 32 Raster Operation Units.

Compare those specifications to the Radeon HD 4890 2GB, which uses a 55 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 RAM is set to run at a speed of 975 MHz on this particular model. It features 800(160x5) SPUs as well as 40 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video 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 most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
