GeForce GTX 1630 vs GeForce RTX 4090

Intro

The GeForce GTX 1630 has a clock speed of 1740 MHz and a GDDR6 memory frequency of 1500 MHz. It also makes use of a 64-bit bus, and uses a 12 nm design. It features 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

Compare those specs to the GeForce RTX 4090, which makes use of a 4 nm design. nVidia has clocked the core speed at 2235 MHz. The GDDR6X RAM runs at a speed of 1325 MHz on this specific card. It features 16384 SPUs as well as 512 Texture Address Units and 176 ROPs.

GeForce GTX 1630 98304 MB/sec
Difference: 944128 (960%)

Texel Rate

The GeForce RTX 4090 will be quite a bit (approximately 1955%) more effective at texture filtering than the GeForce GTX 1630. (explain)

GeForce RTX 4090 1144320 Mtexels/sec
GeForce GTX 1630 55680 Mtexels/sec
Difference: 1088640 (1955%)

Pixel Rate

The GeForce RTX 4090 is much (more or less 1313%) more effective at FSAA than the GeForce GTX 1630, and also will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce RTX 4090 393360 Mpixels/sec
GeForce GTX 1630 27840 Mpixels/sec
Difference: 365520 (1313%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling 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 record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
