GeForce GT 1030 vs Radeon HD 4730

Intro

Compare those specifications to the Radeon HD 4730, which features GPU clock speed of 700 MHz, and 512 MB of GDDR5 memory running at 900 MHz through a 128-bit bus. It also features 640(128x5) Stream Processors, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
Radeon HD 4730		140 Watts
	Difference: 110 Watts (367%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 4730 will be 17% faster than the GeForce GT 1030 overall, because of its higher data rate. (explain)

Radeon HD 4730		57600 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 8448 (17%)

Texel Rate

The GeForce GT 1030 should be a lot (more or less 81%) more effective at texture filtering than the Radeon HD 4730. (explain)

GeForce GT 1030		40480 Mtexels/sec
Radeon HD 4730		22400 Mtexels/sec
	Difference: 18080 (81%)

Pixel Rate

The GeForce GT 1030 will be a lot (about 261%) better at AA than the Radeon HD 4730, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GT 1030		20240 Mpixels/sec
Radeon HD 4730		5600 Mpixels/sec
	Difference: 14640 (261%)

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 information (in units of MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels the video 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 colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
