GeForce GT 1030 vs Radeon HD 5670

Intro

Compare all that to the Radeon HD 5670, which features a GPU core clock speed of 775 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is made up of 400(80x5) SPUs, 20 Texture Address Units, and 8 ROPs.

GeForce GT 1030		30 Watts
Radeon HD 5670		61 Watts
	Difference: 31 Watts (103%)

Memory Bandwidth

As far as performance goes, the Radeon HD 5670 should in theory be quite a bit better than the GeForce GT 1030 in general. (explain)

Radeon HD 5670		64000 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 14848 (30%)

Texel Rate

The GeForce GT 1030 is quite a bit (about 161%) faster with regards to anisotropic filtering than the Radeon HD 5670. (explain)

GeForce GT 1030		40480 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 24980 (161%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 1030 is the winner, and very much so. (explain)

GeForce GT 1030		20240 Mpixels/sec
Radeon HD 5670		6200 Mpixels/sec
	Difference: 14040 (226%)

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 maximum amount of information (counted in MB per second) that can be transported across 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 the card has DDR RAM, it must be multiplied by 2 once again. If it uses 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
