GeForce GT 1030 vs GeForce GT 340

Intro

Compare those specs to the GeForce GT 340, which uses a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 memory runs at a speed of 850 MHz on this specific card. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GT 340 should be just a bit faster than the GeForce GT 1030 in general. (explain)

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

Texel Rate

The GeForce GT 1030 should be quite a bit (more or less 130%) better at texture filtering than the GeForce GT 340. (explain)

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

Pixel Rate

The GeForce GT 1030 is much (about 360%) better at anti-aliasing than the GeForce GT 340, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce GT 340		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 max amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core clock 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 most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
