GeForce GT 1030 vs GeForce GT 230

Intro

Compare all that to the GeForce GT 230, which makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The DDR3 RAM is set to run at a frequency of 800 MHz on this specific card. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
GeForce GT 230		65 Watts
	Difference: 35 Watts (117%)

Memory Bandwidth

In theory, the GeForce GT 1030 will be 28% quicker than the GeForce GT 230 overall, due to its higher data rate. (explain)

GeForce GT 1030		49152 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 10752 (28%)

Texel Rate

The GeForce GT 1030 will be much (approximately 360%) more effective at texture filtering than the GeForce GT 230. (explain)

GeForce GT 1030		40480 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 31680 (360%)

Pixel Rate

The GeForce GT 1030 will be much (more or less 360%) faster with regards to anti-aliasing than the GeForce GT 230, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 15840 (360%)

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 data (counted in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the 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 amount of pixels that the graphics card can possibly record to the 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 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
