GeForce 8800 GTS (G80) 320MB vs GeForce GT 1030

Intro

Compare all of that to the GeForce GT 1030, which features a core clock frequency of 1265 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 64-bit bus, and makes use of a 16 nm design. It is comprised of 384 SPUs, 32 TAUs, and 16 Raster Operation Units.

The GeForce GT 1030 will be much (approximately 64%) more effective at AF than the GeForce 8800 GTS (G80) 320MB. (explain)

GeForce GT 1030		40480 Mtexels/sec
GeForce 8800 GTS (G80) 320MB		24624 Mtexels/sec
	Difference: 15856 (64%)

Pixel Rate

The GeForce GT 1030 is quite a bit (about 97%) better at AA than the GeForce 8800 GTS (G80) 320MB, and also will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce 8800 GTS (G80) 320MB		10260 Mpixels/sec
	Difference: 9980 (97%)

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 moved past the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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