GeForce GTX 1630 vs GeForce GTX 460

Intro

Compare that to the GeForce GTX 460, which comes with a core clock frequency of 675 MHz and a GDDR5 memory frequency of 900 MHz. It also makes use of a 192-bit bus, and uses a 40 nm design. It features 336 SPUs, 56 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
GeForce GTX 460		150 Watts
	Difference: 75 Watts (100%)

Memory Bandwidth

In theory, the GeForce GTX 1630 should be just a bit faster than the GeForce GTX 460 overall. (explain)

GeForce GTX 1630		98304 MB/sec
GeForce GTX 460		86400 MB/sec
	Difference: 11904 (14%)

Texel Rate

The GeForce GTX 1630 should be a lot (more or less 47%) faster with regards to anisotropic filtering than the GeForce GTX 460. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 17880 (47%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 1630 is a better choice, by far. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTX 460		16200 Mpixels/sec
	Difference: 11640 (72%)

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 maximum amount of data (counted in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card 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 applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
