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

Texel Rate

The GeForce GT 1030 should be a lot (about 69%) faster with regards to 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

The GeForce GT 1030 is much (about 69%) more effective at anti-aliasing than the Radeon HD 4770, and also should be capable of handling higher resolutions while still performing well. (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.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
