GeForce GT 450 (OEM) vs GeForce GTX 1630

Intro

The GeForce GT 450 (OEM) uses a 40 nm design. nVidia has clocked the core speed at 790 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this card. It features 144 SPUs as well as 24 Texture Address Units and 24 ROPs.

Compare those specs to the GeForce GTX 1630, which has a clock frequency of 1740 MHz and a GDDR6 memory speed of 1500 MHz. It also makes use of a 64-bit bus, and makes use of a 12 nm design. It is comprised of 512 SPUs, 32 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once 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 in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
