GeForce GT 1030 vs Radeon HD 5770

Intro

Compare that to the Radeon HD 5770, which has a core clock frequency of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also features a 128-bit bus, and uses a 40 nm design. It is made up of 800(160x5) SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Texel Rate

The GeForce GT 1030 should be a little bit (approximately 19%) faster with regards to texture filtering than the Radeon HD 5770. (explain)

GeForce GT 1030		40480 Mtexels/sec
Radeon HD 5770		34000 Mtexels/sec
	Difference: 6480 (19%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 1030 is superior to the Radeon HD 5770, by far. (explain)

GeForce GT 1030		20240 Mpixels/sec
Radeon HD 5770		13600 Mpixels/sec
	Difference: 6640 (49%)

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 largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
