GeForce GT 1030 vs Radeon HD 4770

Intro

Compare all that to the Radeon HD 4770, which comes with a core clock frequency of 750 MHz and a GDDR5 memory frequency of 800 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is made up of 640(128x5) SPUs, 32 Texture Address Units, and 16 ROPs.

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

Texel Rate

The GeForce GT 1030 should be quite a bit (approximately 69%) more effective at AF 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 lots of anti-aliasing is important to you, then the GeForce GT 1030 is a better choice, 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: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
