GeForce GT 1030 vs GeForce GT 340 1GB

Intro

Compare those specifications to the GeForce GT 340 1GB, which features GPU core speed of 550 MHz, and 1024 MB of GDDR5 RAM set to run at 850 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 32 Texture Address Units, and 8 Raster Operation Units.

GeForce GT 1030		30 Watts
GeForce GT 340 1GB		69 Watts
	Difference: 39 Watts (130%)

Memory Bandwidth

Performance-wise, the GeForce GT 340 1GB should in theory be a small bit superior to the GeForce GT 1030 overall. (explain)

GeForce GT 340 1GB		54400 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 5248 (11%)

Texel Rate

The GeForce GT 1030 should be much (approximately 130%) better at texture filtering than the GeForce GT 340 1GB. (explain)

GeForce GT 1030		40480 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 22880 (130%)

Pixel Rate

If using lots of anti-aliasing 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 340 1GB		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 maximum amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
