GeForce GTX 560 vs Radeon HD 6870

Intro

The GeForce GTX 560 comes with a core clock frequency of 810 MHz and a GDDR5 memory speed of 1001 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It is made up of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.

Compare all that to the Radeon HD 6870, which has a clock speed of 900 MHz and a GDDR5 memory frequency of 1050 MHz. It also features a 256-bit bus, and uses a 40 nm design. It is made up of 1120 SPUs, 56 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560 150 Watts
Radeon HD 6870 151 Watts
Difference: 1 Watts (1%)

Memory Bandwidth

Theoretically, the Radeon HD 6870 should perform a bit faster than the GeForce GTX 560 in general. (explain)

Radeon HD 6870 134400 MB/sec
GeForce GTX 560 128128 MB/sec
Difference: 6272 (5%)

Texel Rate

The Radeon HD 6870 is just a bit (approximately 11%) better at anisotropic filtering than the GeForce GTX 560. (explain)

GeForce GTX 560 45360 Mtexels/sec
Difference: 5040 (11%)

Pixel Rate

The Radeon HD 6870 should be a small bit (more or less 11%) faster with regards to full screen anti-aliasing than the GeForce GTX 560, and capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon HD 6870 28800 Mpixels/sec
GeForce GTX 560 25920 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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the 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 number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.

Price range is the same and yet AMD won this one.
Im a Nvidia fan but I admit for price you should go with 6870.
dan says:
AMD HD-6870 is far superior than gtx 560.on the other hand gtx560 is more expensive
SP33D says:
These results are not accurate enough. All 560's are different. The current 560 i have is not the Ti but out-performs a 6870. Not being biased or a fanboy. I have experienced using a 6870 alone and in crossfire but the performance in games with the 560 is far better.
AMD fan says:

Do u mean 560 can beat 6870cf?
genius.

but i have experirnce using 6870cf can beat 580,,,lol

PNN says:
Having used both (a Sapphire 6870 and an EVGA 560), the 6870 seems to be superior in most applications, however, there are certain games (such as BF3 or Hawken) where the 560 outperforms the 6870.
strat says:
My gtx560 is at 950mhz vs this 810mhz i got almost 20% OC on my card staple all day. voltage went from 1.012 to 1.050.
anoyness says:
My 560 competes with a 6950 in most cases and i have physc
lold says:
what is amazing :D this ppl who say that THEIR's GTX560 compete with hd6950 6990

They must have some alien GTX560 that is manufactured especially for those people :D

Yansen Haryanto says:
i like nvidia card but when i see this result! i choise amd! why? it's more cheaper! and it's only have increased 1 WATT TDP! for that some performance increase and 1 thing is important is! the CHEAP PRICE!
mkultra says:
Went from gtx 560 to amd radeon 6870.
The difference aren't as small as the chart describes.
The AMD over-performed the nvidia card by a landslide
