VS

GeForce GTX 560 Ti 448 vs Radeon HD 3870 X2 1GB

Intro

The GeForce GTX 560 Ti 448 comes with a clock speed of 732 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 320-bit memory bus, and uses a 40 nm design. It features 448 SPUs, 56 Texture Address Units, and 40 ROPs.

Compare all of that to the Radeon HD 3870 X2 1GB, which has a GPU core clock speed of 825 MHz, and 1024 MB of GDDR4 RAM set to run at 1126 MHz through a 256-bit bus. It also features 320(64x5) SPUs, 16 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon HD 3870 X2 1GB should perform a small bit faster than the GeForce GTX 560 Ti 448 in general. (explain)

Radeon HD 3870 X2 1GB 144128 MB/sec
GeForce GTX 560 Ti 448 144000 MB/sec
Difference: 128 (0%)

Texel Rate

The GeForce GTX 560 Ti 448 is quite a bit (about 55%) more effective at texture filtering than the Radeon HD 3870 X2 1GB. (explain)

GeForce GTX 560 Ti 448 40992 Mtexels/sec
Radeon HD 3870 X2 1GB 26400 Mtexels/sec
Difference: 14592 (55%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 560 Ti 448 is a better choice, not by a very large margin though. (explain)

GeForce GTX 560 Ti 448 29280 Mpixels/sec
Radeon HD 3870 X2 1GB 26400 Mpixels/sec
Difference: 2880 (11%)

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. 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 many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
