GeForce GTX 1630 vs GeForce GTX 460 1GB

Intro

Compare all that to the GeForce GTX 460 1GB, which makes use of a 40 nm design. nVidia has set the core frequency at 675 MHz. The GDDR5 RAM is set to run at a frequency of 900 MHz on this card. It features 336 SPUs along with 56 TAUs and 32 Rasterization Operator Units.

GeForce GTX 460 1GB		160 Watts
	Difference: 85 Watts (113%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 1GB should be 17% faster than the GeForce GTX 1630 in general, due to its greater bandwidth. (explain)

GeForce GTX 460 1GB		115200 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 16896 (17%)

Texel Rate

The GeForce GTX 1630 is quite a bit (more or less 47%) more effective at anisotropic filtering than the GeForce GTX 460 1GB. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 17880 (47%)

Pixel Rate

The GeForce GTX 1630 will be quite a bit (about 29%) faster with regards to AA than the GeForce GTX 460 1GB, and capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTX 460 1GB		21600 Mpixels/sec
	Difference: 6240 (29%)

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 (measured in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
