GeForce GT 1030 vs Radeon HD 5450

Intro

Compare those specs to the Radeon HD 5450, which uses a 40 nm design. AMD has clocked the core frequency at 650 MHz. The DDR3 RAM is set to run at a speed of 800 MHz on this model. It features 80(16x5) SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Radeon HD 5450		12800 MB/sec
	Difference: 36352 (284%)

Texel Rate

The GeForce GT 1030 will be quite a bit (approximately 678%) more effective at AF than the Radeon HD 5450. (explain)

GeForce GT 1030		40480 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 35280 (678%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 1030 is superior to the Radeon HD 5450, and very much so. (explain)

GeForce GT 1030		20240 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 17640 (678%)

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 maximum amount of information (in units of MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines 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 output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
