GeForce GT 1030 vs Radeon HD 4770

Intro

Compare that to the Radeon HD 4770, which has a GPU core clock speed of 750 MHz, and 512 MB of GDDR5 memory running at 800 MHz through a 128-bit bus. It also is comprised of 640(128x5) SPUs, 32 TAUs, and 16 Raster Operation Units.

GeForce GT 1030		49152 MB/sec
	Difference: 2048 (4%)

Texel Rate

The GeForce GT 1030 is quite a bit (more or less 69%) better at texture filtering than the Radeon HD 4770. (explain)

GeForce GT 1030		40480 Mtexels/sec
Radeon HD 4770		24000 Mtexels/sec
	Difference: 16480 (69%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GT 1030 is the winner, by far. (explain)

GeForce GT 1030		20240 Mpixels/sec
Radeon HD 4770		12000 Mpixels/sec
	Difference: 8240 (69%)

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 (counted in MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the 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 are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video 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 most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also 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 potential to get to the maximum fill rate.
