GeForce 9800 GT 1GB vs Radeon HD 6770

Intro

The GeForce 9800 GT 1GB has a GPU core clock speed of 600 MHz, and the 1024 MB of GDDR3 RAM is set to run at 900 MHz through a 256-bit bus. It also is comprised of 112 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Compare all that to the Radeon HD 6770, which makes use of a 40 nm design. AMD has clocked the core frequency at 900 MHz. The GDDR5 memory is set to run at a frequency of 1050 MHz on this model. It features 800 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the Radeon HD 6770 should be 17% quicker than the GeForce 9800 GT 1GB overall, because of its higher data rate. (explain)

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

Texel Rate

The Radeon HD 6770 should be just a bit (more or less 7%) better at AF 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 a lot (more or less 50%) better at FSAA than the GeForce 9800 GT 1GB, and also should be able to handle higher screen resolutions more effectively. (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 largest amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

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