GeForce GTX 1630 vs GeForce GTX 465

Intro

Compare those specifications to the GeForce GTX 465, which makes use of a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 memory is set to run at a frequency of 802 MHz on this particular model. It features 352 SPUs along with 44 TAUs and 32 Rasterization Operator Units.

GeForce GTX 1630		98304 MB/sec
	Difference: 4288 (4%)

Texel Rate

The GeForce GTX 1630 should be quite a bit (about 108%) faster with regards to anisotropic filtering than the GeForce GTX 465. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 28972 (108%)

Pixel Rate

The GeForce GTX 1630 should be quite a bit (about 43%) more effective at full screen anti-aliasing than the GeForce GTX 465, and also will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 8416 (43%)

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 max amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number is worked out 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
