GeForce GTX 1630 vs GeForce GTX 465

Intro

Compare all of that to the GeForce GTX 465, which uses a 40 nm design. nVidia has clocked the core frequency at 607 MHz. The GDDR5 memory runs at a frequency of 802 MHz on this particular model. It features 352 SPUs as well as 44 TAUs and 32 ROPs.

Power Consumption (Max TDP)

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

Memory Bandwidth

Performance-wise, the GeForce GTX 465 should in theory be a little bit better than the GeForce GTX 1630 overall. (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 (more or less 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 the winner, 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: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's 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 can be processed per second. This is calculated by multiplying the total amount of texture units of the card by the core 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
