GeForce GTX 750 vs Radeon RX 580

Intro

The GeForce GTX 750 makes use of a 28 nm design. nVidia has set the core speed at 1020 MHz. The GDDR5 RAM works at a speed of 1250 MHz on this specific model. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Compare all of that to the Radeon RX 580, which features core speeds of 1257 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 memory. It features 2304 SPUs as well as 144 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
