GeForce 8800 GT 512MB vs GeForce GT 1030

Intro

Compare those specifications to the GeForce GT 1030, which has GPU core speed of 1265 MHz, and 2048 MB of GDDR5 memory running at 1502 MHz through a 64-bit bus. It also is made up of 384 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
GeForce 8800 GT 512MB		105 Watts
	Difference: 75 Watts (250%)

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GT 512MB should be 17% quicker than the GeForce GT 1030 overall, because of its higher bandwidth. (explain)

GeForce 8800 GT 512MB		57600 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 8448 (17%)

Texel Rate

The GeForce GT 1030 should be just a bit (approximately 20%) more effective at AF than the GeForce 8800 GT 512MB. (explain)

GeForce GT 1030		40480 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 6880 (20%)

Pixel Rate

The GeForce GT 1030 should be much (more or less 111%) faster with regards to full screen anti-aliasing than the GeForce 8800 GT 512MB, and will be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce 8800 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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
