GeForce 8800 GT 1GB vs GeForce GTX 470

Intro

Compare those specifications to the GeForce GTX 470, which uses a 40 nm design. nVidia has clocked the core speed at 607 MHz. The GDDR5 memory is set to run at a frequency of 837 MHz on this card. It features 448 SPUs as well as 56 Texture Address Units and 40 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 1GB		105 Watts
GeForce GTX 470		215 Watts
	Difference: 110 Watts (105%)

Memory Bandwidth

Performance-wise, the GeForce GTX 470 should in theory be much superior to the GeForce 8800 GT 1GB overall. (explain)

GeForce GTX 470		133920 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 76320 (133%)

Texel Rate

The GeForce GTX 470 will be a bit (approximately 1%) more effective at AF than the GeForce 8800 GT 1GB. (explain)

GeForce GTX 470		33992 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 392 (1%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 470 is superior to the GeForce 8800 GT 1GB, and very much so. (explain)

GeForce GTX 470		24280 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 14680 (153%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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