GeForce GTX 560 Ti vs Radeon HD 5870

Intro

The GeForce GTX 560 Ti comes with core speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs as well as 64 TAUs and 32 ROPs.

Compare that to the Radeon HD 5870, which uses a 40 nm design. AMD has set the core speed at 850 MHz. The GDDR5 RAM works at a frequency of 1200 MHz on this model. It features 1600(320x5) SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560 Ti 170 Watts
Radeon HD 5870 188 Watts
Difference: 18 Watts (11%)

Memory Bandwidth

In theory, the Radeon HD 5870 should perform a small bit faster than the GeForce GTX 560 Ti in general. (explain)

Radeon HD 5870 153600 MB/sec
GeForce GTX 560 Ti 128256 MB/sec
Difference: 25344 (20%)

Texel Rate

The Radeon HD 5870 will be much (more or less 29%) faster with regards to AF than the GeForce GTX 560 Ti. (explain)

Radeon HD 5870 68000 Mtexels/sec
GeForce GTX 560 Ti 52608 Mtexels/sec
Difference: 15392 (29%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 5870 is a better choice, but not by far. (explain)

Radeon HD 5870 27200 Mpixels/sec
GeForce GTX 560 Ti 26304 Mpixels/sec
Difference: 896 (3%)

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 data (counted in MB per second) that can be transported across the external memory interface within a second. The number is worked out 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 DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). 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.

It seems that HD 5870 has left GTX 560 Ti behind in performance.

Niko says:

I just bought a 5870 for 149 shipped. the 560 Ti is going for 200 right now, not worth the 50 bucks in my opinion if your just going with a single card setup

Alex says:

Which is better between the HD 5870 and GTX 560 IT? but seeing the results is better HD 5870, but I hesitate and price are the same? x (

Help! please
