GeForce GT 1030 vs Radeon HD 3650

Intro

Compare those specs to the Radeon HD 3650, which comes with a core clock speed of 725 MHz and a GDDR4 memory speed of 800 MHz. It also uses a 128-bit bus, and uses a 55 nm design. It features 120(24x5) SPUs, 8 Texture Address Units, and 4 ROPs.

The GeForce GT 1030 is quite a bit (about 598%) more effective at AF than the Radeon HD 3650. (explain)

GeForce GT 1030		40480 Mtexels/sec
Radeon HD 3650		5800 Mtexels/sec
	Difference: 34680 (598%)

Pixel Rate

If running with 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
Radeon HD 3650		2900 Mpixels/sec
	Difference: 17340 (598%)

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 information (measured in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
