GeForce GT 1030 vs GeForce GT 240 GDDR5

Intro

Compare those specs to the GeForce GT 240 GDDR5, which comes with core clock speeds of 550 MHz on the GPU, and 850 MHz on the 512 MB of GDDR5 memory. 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

Performance-wise, the GeForce GT 240 GDDR5 should in theory be a little bit superior to the GeForce GT 1030 overall. (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 anisotropic filtering 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 should be quite a bit (more or less 360%) more effective at AA than the GeForce GT 240 GDDR5, and also should be capable of handling higher screen 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: Memory bandwidth is the max amount of data (measured in MB per second) that can be moved across 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 should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
