GeForce 9800 GT 1GB vs Radeon RX 470

Intro

Compare all that to the Radeon RX 470, which features a clock speed of 926 MHz and a GDDR5 memory speed of 1650 MHz. It also features a 256-bit memory bus, and uses a 14 nm design. It features 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9800 GT 1GB		105 Watts
Radeon RX 470		120 Watts
	Difference: 15 Watts (14%)

Memory Bandwidth

The Radeon RX 470, in theory, should be quite a bit faster than the GeForce 9800 GT 1GB in general. (explain)

Radeon RX 470		211200 MB/sec
GeForce 9800 GT 1GB		57600 MB/sec
	Difference: 153600 (267%)

Texel Rate

The Radeon RX 470 will be a lot (more or less 253%) more effective at texture filtering than the GeForce 9800 GT 1GB. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce 9800 GT 1GB		33600 Mtexels/sec
	Difference: 84928 (253%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 470 is superior to the GeForce 9800 GT 1GB, and very much so. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce 9800 GT 1GB		9600 Mpixels/sec
	Difference: 20032 (209%)

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 data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type 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 anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). 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 get to the maximum fill rate.
