GeForce GTX 1650 vs Radeon HD 4870 512MB

Intro

The GeForce GTX 1650 uses a 12 nm design. nVidia has clocked the core frequency at 1485 MHz. The GDDR5 memory is set to run at a frequency of 2001 MHz on this specific model. It features 896 SPUs along with 56 Texture Address Units and 32 Rasterization Operator Units.

Compare those specifications to the Radeon HD 4870 512MB, which makes use of a 55 nm design. AMD has set the core speed at 750 MHz. The GDDR5 RAM runs at a speed of 900 MHz on this card. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's 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 are applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, 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 number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines 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 output 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 max fill rate.
