GeForce GTX 470 vs Radeon HD 4870 X2

Intro

The GeForce GTX 470 uses a 40 nm design. nVidia has clocked the core frequency at 607 MHz. The GDDR5 RAM works at a frequency of 837 MHz on this card. It features 448 SPUs along with 56 Texture Address Units and 40 Rasterization Operator Units.

Compare those specifications to the Radeon HD 4870 X2, which comes with a GPU core clock speed of 750 MHz, and 1024 MB of GDDR5 memory set to run at 900 MHz through a 256-bit bus. It also is comprised of 800(160x5) Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 470 215 Watts
Radeon HD 4870 X2 350 Watts
Difference: 135 Watts (63%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 4870 X2 will be 72% quicker than the GeForce GTX 470 in general, due to its higher data rate. (explain)

Radeon HD 4870 X2 230400 MB/sec
GeForce GTX 470 133920 MB/sec
Difference: 96480 (72%)

Texel Rate

The Radeon HD 4870 X2 should be a lot (approximately 77%) better at AF than the GeForce GTX 470. (explain)

Radeon HD 4870 X2 60000 Mtexels/sec
GeForce GTX 470 33992 Mtexels/sec
Difference: 26008 (77%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 470 is the winner, not by a very large margin though. (explain)

GeForce GTX 470 24280 Mpixels/sec
Radeon HD 4870 X2 24000 Mpixels/sec
Difference: 280 (1%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
