GeForce GT 1030 vs Radeon HD 5770

Intro

Compare all of that to the Radeon HD 5770, which comes with a clock frequency of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is comprised of 800(160x5) SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
Radeon HD 5770		108 Watts
	Difference: 78 Watts (260%)

Memory Bandwidth

Theoretically, the Radeon HD 5770 should perform much faster than the GeForce GT 1030 overall. (explain)

Radeon HD 5770		76800 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 27648 (56%)

Texel Rate

The GeForce GT 1030 should be a little bit (more or less 19%) more effective at anisotropic filtering than the Radeon HD 5770. (explain)

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

Pixel Rate

The GeForce GT 1030 will be quite a bit (approximately 49%) faster with regards to FSAA than the Radeon HD 5770, and should be able to handle higher screen resolutions without slowing down too much. (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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

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