GeForce 8800 GTX vs GeForce GT 1030

Intro

Compare all of that to the GeForce GT 1030, which features GPU clock speed of 1265 MHz, and 2048 MB of GDDR5 memory running at 1502 MHz through a 64-bit bus. It also is comprised of 384 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

GeForce GT 1030		30 Watts
GeForce 8800 GTX		155 Watts
	Difference: 125 Watts (417%)

Memory Bandwidth

In theory, the GeForce 8800 GTX should perform quite a bit faster than the GeForce GT 1030 overall. (explain)

GeForce 8800 GTX		86400 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 37248 (76%)

Texel Rate

The GeForce GT 1030 should be a little bit (more or less 10%) more effective at AF than the GeForce 8800 GTX. (explain)

GeForce GT 1030		40480 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 3680 (10%)

Pixel Rate

The GeForce GT 1030 is a lot (approximately 47%) better at full screen anti-aliasing than the GeForce 8800 GTX, and also should be capable of handling higher resolutions better. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 6440 (47%)

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 maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If 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 amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock 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 applied in a 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. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
