GeForce GTX 1630 vs GeForce GTX 465

Intro

Compare all that to the GeForce GTX 465, which makes use of a 40 nm design. nVidia has clocked the core frequency at 607 MHz. The GDDR5 memory is set to run at a frequency of 802 MHz on this specific card. It features 352 SPUs along with 44 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
GeForce GTX 465		200 Watts
	Difference: 125 Watts (167%)

Memory Bandwidth

In theory, the GeForce GTX 465 will be 4% faster than the GeForce GTX 1630 overall, because of its greater bandwidth. (explain)

GeForce GTX 465		102592 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 4288 (4%)

Texel Rate

The GeForce GTX 1630 should be much (approximately 108%) better at AF than the GeForce GTX 465. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1630 is superior to the GeForce GTX 465, by a large margin. (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: Bandwidth is the max amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
