GeForce GT 1030 vs Radeon HD 4770

Intro

Compare those specs to the Radeon HD 4770, which uses a 40 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 RAM is set to run at a frequency of 800 MHz on this specific model. It features 640(128x5) SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

GeForce GT 1030		30 Watts
Radeon HD 4770		80 Watts
	Difference: 50 Watts (167%)

Memory Bandwidth

As far as performance goes, the Radeon HD 4770 should theoretically be just a bit better than the GeForce GT 1030 overall. (explain)

Radeon HD 4770		51200 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 2048 (4%)

Texel Rate

The GeForce GT 1030 should be quite a bit (more or less 69%) more effective at anisotropic 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 using a high 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
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 largest amount of data (in units of MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a 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 - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
