GeForce 9800 GT 1GB vs Radeon HD 6770

Intro

The GeForce 9800 GT 1GB uses a 65/55 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 memory works at a speed of 900 MHz on this specific card. It features 112 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

Compare those specifications to the Radeon HD 6770, which features GPU core speed of 900 MHz, and 512 MB of GDDR5 RAM set to run at 1050 MHz through a 128-bit bus. It also is made up of 800 Stream Processors, 40 TAUs, and 16 ROPs.

GeForce 9800 GT 1GB 105 Watts
Radeon HD 6770 108 Watts
Difference: 3 Watts (3%)

Memory Bandwidth

In theory, the Radeon HD 6770 will be 17% quicker than the GeForce 9800 GT 1GB overall, because of its greater bandwidth. (explain)

Radeon HD 6770 67200 MB/sec
GeForce 9800 GT 1GB 57600 MB/sec
Difference: 9600 (17%)

Texel Rate

The Radeon HD 6770 is just a bit (more or less 7%) better at anisotropic filtering than the GeForce 9800 GT 1GB. (explain)

Radeon HD 6770 36000 Mtexels/sec
GeForce 9800 GT 1GB 33600 Mtexels/sec
Difference: 2400 (7%)

Pixel Rate

The Radeon HD 6770 will be much (more or less 50%) more effective at AA than the GeForce 9800 GT 1GB, and also capable of handling higher resolutions better. (explain)

Radeon HD 6770 14400 Mpixels/sec
GeForce 9800 GT 1GB 9600 Mpixels/sec
Difference: 4800 (50%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units of the card 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. 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 rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
