GeForce GT 1030 vs GeForce GT 340 1GB

Intro

Compare all that to the GeForce GT 340 1GB, which has a GPU core clock 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 SPUs, 32 Texture Address Units, and 8 ROPs.

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

Texel Rate

The GeForce GT 1030 will be quite a bit (about 130%) more effective 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 a high screen resolution is important to you, then the GeForce GT 1030 is a better choice, by far. (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 (counted in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 ability to reach the maximum fill rate.
