GeForce GTS 450 vs GeForce GTX 1650

Intro

The GeForce GTS 450 features a clock frequency of 783 MHz and a GDDR5 memory frequency of 902 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 192 SPUs, 32 TAUs, and 16 ROPs.

Compare all of that to the GeForce GTX 1650, which comes with a GPU core clock speed of 1485 MHz, and 4096 MB of GDDR5 RAM set to run at 2001 MHz through a 128-bit bus. It also features 896 SPUs, 56 TAUs, and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics 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 most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
