GeForce 920M vs GeForce GT 1030

Intro

Compare those specs to the GeForce GT 1030, which comes with GPU core speed of 1265 MHz, and 2048 MB of GDDR5 memory running at 1502 MHz through a 64-bit bus. It also features 384 SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 1030 should theoretically be quite a bit faster than the GeForce 920M in general. (explain)

GeForce GT 1030		49152 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 34752 (241%)

Texel Rate

The GeForce GT 1030 will be a lot (more or less 33%) faster with regards to AF than the GeForce 920M. (explain)

GeForce GT 1030		40480 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 9952 (33%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GT 1030 is a better choice, by a large margin. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 12608 (165%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
