GeForce GTX 1650 vs Radeon HD 4870 2GB

Intro

The GeForce GTX 1650 uses a 12 nm design. nVidia has set the core speed at 1485 MHz. The GDDR5 memory is set to run at a frequency of 8000 MHz on this particular card. It features 896 SPUs as well as 56 Texture Address Units and 32 Rasterization Operator Units.

Compare that to the Radeon HD 4870 2GB, which uses a 55 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR5 RAM works at a speed of 900 MHz on this model. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that are processed per second. This number 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 the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
