GeForce GTX 560 Ti vs Radeon HD 5870

Intro

The GeForce GTX 560 Ti makes use of a 40 nm design. nVidia has clocked the core frequency at 822 MHz. The GDDR5 RAM is set to run at a speed of 1002 MHz on this specific card. It features 384 SPUs along with 64 TAUs and 32 ROPs.

Compare all of that to the Radeon HD 5870, which comes with core clock speeds of 850 MHz on the GPU, and 1200 MHz on the 1024 MB of GDDR5 memory. It features 1600(320x5) SPUs as well as 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 will be 20% quicker than the GeForce GTX 560 Ti overall, due to its greater data rate. (explain)

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

Texel Rate

The Radeon HD 5870 should be quite a bit (about 29%) faster with regards to texture filtering 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

The Radeon HD 5870 should be a small bit (more or less 3%) better at FSAA than the GeForce GTX 560 Ti, and also should be able to handle higher resolutions without slowing down too much. (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: Memory bandwidth is the max amount of data (measured in MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, 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 most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 - the lower the bandwidth is, the lower the ability 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
