GeForce GT 1030 vs GeForce GT 240 GDDR5

Intro

Compare that to the GeForce GT 240 GDDR5, which makes use of a 40 nm design. nVidia has set the core frequency at 550 MHz. The GDDR5 RAM runs at a frequency of 850 MHz on this particular model. It features 96 SPUs along with 32 TAUs and 8 Rasterization Operator Units.

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

Texel Rate

The GeForce GT 1030 will be much (more or less 130%) more effective at 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

If running with high levels of AA is important to you, then the GeForce GT 1030 is the winner, and very much so. (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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
