GeForce GTX 1650 vs Radeon HD 4890 2GB

Intro

The GeForce GTX 1650 has a clock speed of 1485 MHz and a GDDR5 memory frequency of 8000 MHz. It also makes use of a 128-bit memory bus, and uses a 12 nm design. It is comprised of 896 SPUs, 56 TAUs, and 32 Raster Operation Units.

Compare all that to the Radeon HD 4890 2GB, which uses a 55 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM runs at a frequency of 975 MHz on this specific model. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 get to the max fill rate.
