GeForce 9600 GT 1GB vs Radeon HD 5770

Intro

Compare all of that to the Radeon HD 5770, which uses a 40 nm design. AMD has clocked the core frequency at 850 MHz. The GDDR5 memory runs at a speed of 1200 MHz on this particular model. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GT 1GB		95 Watts
Radeon HD 5770		108 Watts
	Difference: 13 Watts (14%)

Memory Bandwidth

Theoretically, the Radeon HD 5770 should be much faster than the GeForce 9600 GT 1GB in general. (explain)

Radeon HD 5770		76800 MB/sec
GeForce 9600 GT 1GB		57600 MB/sec
	Difference: 19200 (33%)

Texel Rate

The Radeon HD 5770 should be a lot (more or less 63%) better at AF than the GeForce 9600 GT 1GB. (explain)

Radeon HD 5770		34000 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 13200 (63%)

Pixel Rate

The Radeon HD 5770 is quite a bit (more or less 31%) better at full screen anti-aliasing than the GeForce 9600 GT 1GB, and also will be able to handle higher screen resolutions while still performing well. (explain)

Radeon HD 5770		13600 Mpixels/sec
GeForce 9600 GT 1GB		10400 Mpixels/sec
	Difference: 3200 (31%)

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 largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. 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 better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
