GeForce GT 1030 vs GeForce GT 440 1.5GB

Intro

Compare all of that to the GeForce GT 440 1.5GB, which has GPU clock speed of 594 MHz, and 1536 MB of GDDR3 memory set to run at 900 MHz through a 192-bit bus. It also is comprised of 144 SPUs, 24 Texture Address Units, and 24 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
GeForce GT 440 1.5GB		56 Watts
	Difference: 26 Watts (87%)

Memory Bandwidth

In theory, the GeForce GT 1030 should be 14% quicker than the GeForce GT 440 1.5GB overall, because of its greater data rate. (explain)

GeForce GT 1030		49152 MB/sec
GeForce GT 440 1.5GB		43200 MB/sec
	Difference: 5952 (14%)

Texel Rate

The GeForce GT 1030 should be quite a bit (more or less 184%) more effective at anisotropic filtering than the GeForce GT 440 1.5GB. (explain)

GeForce GT 1030		40480 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 26224 (184%)

Pixel Rate

The GeForce GT 1030 is much (approximately 42%) faster with regards to AA than the GeForce GT 440 1.5GB, and also will be able to handle higher screen resolutions more effectively. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce GT 440 1.5GB		14256 Mpixels/sec
	Difference: 5984 (42%)

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 largest amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of 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 amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 bandwidth is, the lower the ability to get to the maximum fill rate.
