GeForce 9400 GT 256MB vs GeForce GTX 1630

Intro

The GeForce 9400 GT 256MB has a core clock speed of 550 MHz and a GDDR2 memory frequency of 400 MHz. It also makes use of a 128-bit bus, and uses a 65 nm design. It is made up of 16 SPUs, 8 TAUs, and 4 Raster Operation Units.

Compare those specifications to the GeForce GTX 1630, which has GPU core speed of 1740 MHz, and 4096 MB of GDDR6 RAM running at 1500 MHz through a 64-bit bus. It also is made up of 512 SPUs, 32 TAUs, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
