GeForce 8600 GT 512MB DDR2 vs GeForce GT 240 GDDR5 1GB

Intro

The GeForce 8600 GT 512MB DDR2 makes use of a 80 nm design. nVidia has set the core speed at 540 MHz. The DDR2 memory is set to run at a speed of 400 MHz on this specific card. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Compare those specs to the GeForce GT 240 GDDR5 1GB, which comes with GPU core speed of 550 MHz, and 1024 MB of GDDR5 memory set to run at 850 MHz through a 128-bit bus. It also features 96 Stream Processors, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 512MB DDR2 47 Watts
GeForce GT 240 GDDR5 1GB 70 Watts
Difference: 23 Watts (49%)

Memory Bandwidth

As far as performance goes, the GeForce GT 240 GDDR5 1GB should theoretically be a lot superior to the GeForce 8600 GT 512MB DDR2 overall. (explain)

GeForce GT 240 GDDR5 1GB 54400 MB/sec
GeForce 8600 GT 512MB DDR2 12800 MB/sec
Difference: 41600 (325%)

Texel Rate

The GeForce GT 240 GDDR5 1GB will be much (more or less 104%) better at texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)

GeForce GT 240 GDDR5 1GB 17600 Mtexels/sec
GeForce 8600 GT 512MB DDR2 8640 Mtexels/sec
Difference: 8960 (104%)

Pixel Rate

The GeForce GT 240 GDDR5 1GB should be a small bit (about 2%) faster with regards to anti-aliasing than the GeForce 8600 GT 512MB DDR2, and should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GT 240 GDDR5 1GB 4400 Mpixels/sec
GeForce 8600 GT 512MB DDR2 4320 Mpixels/sec
Difference: 80 (2%)

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: Bandwidth is the max amount of information (counted in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount 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 drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
