GeForce 8800 GT 512MB vs GeForce GTX 650


Intro

The GeForce 8800 GT 512MB makes use of a 65 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 memory runs at a speed of 900 MHz on this specific model. It features 112 SPUs as well as 56 Texture Address Units and 16 ROPs.

Compare that to the GeForce GTX 650, which comes with a clock frequency of 1058 MHz and a GDDR5 memory speed of 1250 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 32 Texture Address Units, and 16 ROPs.

In theory, the GeForce GTX 650 will be 39% quicker than the GeForce 8800 GT 512MB in general, because of its greater data rate. (explain)

GeForce GTX 650 80000 MB/sec
GeForce 8800 GT 512MB 57600 MB/sec
Difference: 22400 (39%)

Texel Rate

The GeForce GTX 650 will be a little bit (approximately 1%) faster with regards to anisotropic filtering than the GeForce 8800 GT 512MB. (explain)

GeForce GTX 650 33856 Mtexels/sec
GeForce 8800 GT 512MB 33600 Mtexels/sec
Difference: 256 (1%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 650 is a better choice, and very much so. (explain)

GeForce GTX 650 16928 Mpixels/sec
GeForce 8800 GT 512MB 9600 Mpixels/sec
Difference: 7328 (76%)

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 maximum amount of information (counted in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If 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 amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
