GeForce GT 1030 vs GeForce GT 220 GDDR3

Intro

Compare that to the GeForce GT 220 GDDR3, which features GPU core speed of 625 MHz, and 512 MB of GDDR3 memory running at 1012 MHz through a 128-bit bus. It also is made up of 48 SPUs, 16 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
GeForce GT 220 GDDR3		58 Watts
	Difference: 28 Watts (93%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 1030 will be 52% faster than the GeForce GT 220 GDDR3 in general, because of its higher bandwidth. (explain)

GeForce GT 1030		49152 MB/sec
GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 16768 (52%)

Texel Rate

The GeForce GT 1030 will be a lot (about 305%) faster with regards to anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

GeForce GT 1030		40480 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 30480 (305%)

Pixel Rate

The GeForce GT 1030 will be quite a bit (approximately 305%) more effective at full screen anti-aliasing than the GeForce GT 220 GDDR3, and also will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 15240 (305%)

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 maximum amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
