GeForce 9800 GT 1GB vs Radeon RX 470

Intro

Compare all that to the Radeon RX 470, which uses a 14 nm design. AMD has clocked the core speed at 926 MHz. The GDDR5 memory runs at a frequency of 1650 MHz on this specific card. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

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

Texel Rate

The Radeon RX 470 will be much (about 253%) better at anisotropic 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

The Radeon RX 470 should be much (more or less 209%) faster with regards to FSAA than the GeForce 9800 GT 1GB, and able to handle higher screen resolutions without losing too much performance. (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 information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
