Compare any two graphics cards:

GeForce 9800 GT 512MB vs GeForce GT 1030

Intro

The GeForce 9800 GT 512MB makes use of a 65/55 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 memory works at a speed of 900 MHz on this particular card. It features 112 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Compare those specs to the GeForce GT 1030, which has a GPU core clock speed of 1265 MHz, and 2048 MB of GDDR5 RAM set to run at 1502 MHz through a 64-bit bus. It also is comprised of 384 SPUs, 32 Texture Address Units, and 16 ROPs.

GeForce GT 1030		40480 Mtexels/sec
GeForce 9800 GT 512MB		33600 Mtexels/sec
	Difference: 6880 (20%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GT 1030 is superior to the GeForce 9800 GT 512MB, and very much so. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce 9800 GT 512MB		9600 Mpixels/sec
	Difference: 10640 (111%)

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.

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out 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 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 the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 get to the maximum fill rate.
