GeForce GT 1030 vs GeForce GTS 150

Intro

Compare those specifications to the GeForce GTS 150, which features GPU core speed of 740 MHz, and 1024 MB of GDDR3 RAM set to run at 500 MHz through a 256-bit bus. It also features 128 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

GeForce GTS 150		32000 MB/sec
	Difference: 17152 (54%)

Texel Rate

The GeForce GTS 150 will be a little bit (approximately 17%) faster with regards to AF than the GeForce GT 1030. (explain)

GeForce GTS 150		47360 Mtexels/sec
GeForce GT 1030		40480 Mtexels/sec
	Difference: 6880 (17%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GT 1030 is a better choice, and very much so. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 8400 (71%)

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 largest amount of information (measured in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, 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 write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
