GeForce GTX 1650 vs Radeon HD 4870 512MB

Intro

The GeForce GTX 1650 has a GPU clock speed of 1485 MHz, and the 4096 MB of GDDR5 memory is set to run at 8000 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 Texture Address Units, and 32 Raster Operation Units.

Compare all of that to the Radeon HD 4870 512MB, which uses a 55 nm design. AMD has set the core speed at 750 MHz. The GDDR5 RAM works at a frequency of 900 MHz on this specific card. It features 800(160x5) SPUs as well as 40 TAUs and 16 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
