GeForce GT 1030 vs GeForce GT 240 GDDR5

Intro

Compare that to the GeForce GT 240 GDDR5, which uses a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 RAM is set to run at a speed of 850 MHz on this specific card. It features 96 SPUs as well as 32 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
GeForce GT 240 GDDR5		70 Watts
	Difference: 40 Watts (133%)

Memory Bandwidth

Theoretically, the GeForce GT 240 GDDR5 should perform a little bit faster than the GeForce GT 1030 in general. (explain)

GeForce GT 240 GDDR5		54400 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 5248 (11%)

Texel Rate

The GeForce GT 1030 will be quite a bit (approximately 130%) faster with regards to AF than the GeForce GT 240 GDDR5. (explain)

GeForce GT 1030		40480 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 22880 (130%)

Pixel Rate

The GeForce GT 1030 is a lot (approximately 360%) better at full screen anti-aliasing than the GeForce GT 240 GDDR5, and should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce GT 240 GDDR5		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 largest amount of data (counted in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory 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 faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units 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 most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core 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 rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
