GeForce GTX 1630 vs GeForce GTX 650 Ti 2GB

Intro

The GeForce GTX 1630 makes use of a 12 nm design. nVidia has set the core frequency at 1740 MHz. The GDDR6 RAM works at a speed of 1500 MHz on this specific card. It features 512 SPUs as well as 32 Texture Address Units and 16 ROPs.

Compare those specifications to the GeForce GTX 650 Ti 2GB, which comes with a clock frequency of 928 MHz and a GDDR5 memory frequency of 1350 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is made up of 768 SPUs, 64 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 can be applied per second. This figure is worked out by multiplying the total number of texture units of the card 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
