GeForce GT 1030 vs GeForce GTX 280

Intro

Compare that to the GeForce GTX 280, which has clock speeds of 602 MHz on the GPU, and 1107 MHz on the 1024 MB of GDDR3 memory. It features 240 SPUs as well as 80 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
GeForce GTX 280		236 Watts
	Difference: 206 Watts (687%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 280 should be quite a bit faster than the GeForce GT 1030 overall. (explain)

GeForce GTX 280		141696 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 92544 (188%)

Texel Rate

The GeForce GTX 280 should be just a bit (more or less 19%) better at texture filtering than the GeForce GT 1030. (explain)

GeForce GTX 280		48160 Mtexels/sec
GeForce GT 1030		40480 Mtexels/sec
	Difference: 7680 (19%)

Pixel Rate

The GeForce GT 1030 is a bit (approximately 5%) better at full screen anti-aliasing than the GeForce GTX 280, and also should be capable of handling higher resolutions more effectively. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce GTX 280		19264 Mpixels/sec
	Difference: 976 (5%)

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 max amount of information (counted in MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 memory bandwidth is, the lower the ability to get to the maximum fill rate.
