GeForce GTX 1630 vs Geforce GTX 770

Intro

Compare all that to the Geforce GTX 770, which uses a 28 nm design. nVidia has set the core speed at 1046 MHz. The GDDR5 RAM is set to run at a speed of 1753 MHz on this model. It features 1536 SPUs as well as 128 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
Geforce GTX 770		230 Watts
	Difference: 155 Watts (207%)

Memory Bandwidth

In theory, the Geforce GTX 770 should perform quite a bit faster than the GeForce GTX 1630 in general. (explain)

Geforce GTX 770		224384 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 126080 (128%)

Texel Rate

The Geforce GTX 770 will be much (more or less 140%) more effective at texture filtering than the GeForce GTX 1630. (explain)

Geforce GTX 770		133888 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 78208 (140%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Geforce GTX 770 is superior to the GeForce GTX 1630, but not by far. (explain)

Geforce GTX 770		33472 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 5632 (20%)

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 maximum amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 can be processed in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
