GeForce GTX 1630 vs GeForce RTX 4090

Intro

Compare those specs to the GeForce RTX 4090, which makes use of a 4 nm design. nVidia has set the core frequency at 2235 MHz. The GDDR6X RAM runs at a speed of 1325 MHz on this specific model. It features 16384 SPUs as well as 512 TAUs and 176 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
GeForce RTX 4090		450 Watts
	Difference: 375 Watts (500%)

Memory Bandwidth

In theory, the GeForce RTX 4090 should perform quite a bit faster than the GeForce GTX 1630 overall. (explain)

GeForce RTX 4090		1042432 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 944128 (960%)

Texel Rate

The GeForce RTX 4090 should be a lot (approximately 1955%) better at anisotropic filtering than the GeForce GTX 1630. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 4090 is a better choice, by a large margin. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount 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 clock speed of the chip. The better this number, the better the video 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 maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
