GeForce 9600 GT 512MB vs Radeon HD 6770

Intro

The GeForce 9600 GT 512MB has a core clock speed of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 256-bit memory bus, and uses a 65/55 nm design. It features 64 SPUs, 32 TAUs, and 16 ROPs.

Compare those specs to the Radeon HD 6770, which comes with a GPU core clock speed of 900 MHz, and 512 MB of GDDR5 RAM running at 1050 MHz through a 128-bit bus. It also is comprised of 800 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GT 512MB 95 Watts
Radeon HD 6770 108 Watts
Difference: 13 Watts (14%)

Memory Bandwidth

In theory, the Radeon HD 6770 should be 17% quicker than the GeForce 9600 GT 512MB overall, due to its greater data rate. (explain)

Radeon HD 6770 67200 MB/sec
GeForce 9600 GT 512MB 57600 MB/sec
Difference: 9600 (17%)

Texel Rate

The Radeon HD 6770 should be quite a bit (approximately 73%) more effective at anisotropic filtering than the GeForce 9600 GT 512MB. (explain)

Radeon HD 6770 36000 Mtexels/sec
GeForce 9600 GT 512MB 20800 Mtexels/sec
Difference: 15200 (73%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 6770 is a better choice, and very much so. (explain)

Radeon HD 6770 14400 Mpixels/sec
GeForce 9600 GT 512MB 10400 Mpixels/sec
Difference: 4000 (38%)

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 maximum amount of information (in units of 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, 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, High Dynamic Range and high resolutions.

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

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