GeForce 9800 GTX vs GeForce GT 1030

Intro

Compare all of that to the GeForce GT 1030, which makes use of a 16 nm design. nVidia has set the core frequency at 1265 MHz. The GDDR5 memory works at a frequency of 1502 MHz on this particular model. It features 384 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
GeForce 9800 GTX		140 Watts
	Difference: 110 Watts (367%)

Memory Bandwidth

Performance-wise, the GeForce 9800 GTX should in theory be quite a bit better than the GeForce GT 1030 in general. (explain)

GeForce 9800 GTX		70400 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 21248 (43%)

Texel Rate

The GeForce 9800 GTX should be a bit (about 7%) more effective at anisotropic filtering than the GeForce GT 1030. (explain)

GeForce 9800 GTX		43200 Mtexels/sec
GeForce GT 1030		40480 Mtexels/sec
	Difference: 2720 (7%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 1030 is the winner, by a large margin. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce 9800 GTX		10800 Mpixels/sec
	Difference: 9440 (87%)

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 largest amount of information (measured in megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
