GeForce GTX 560 vs Radeon HD 6870

Intro

The GeForce GTX 560 features core clock speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs as well as 56 TAUs and 32 ROPs.

Compare those specifications to the Radeon HD 6870, which has GPU core speed of 900 MHz, and 1024 MB of GDDR5 RAM set to run at 1050 MHz through a 256-bit bus. It also is comprised of 1120 Stream Processors, 56 Texture Address Units, and 32 ROPs.

Theoretically speaking, the Radeon HD 6870 should be 5% faster than the GeForce GTX 560 in general, due to its higher data rate. (explain)

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

Texel Rate

The Radeon HD 6870 will be a small bit (approximately 11%) faster with regards to anisotropic filtering than the GeForce GTX 560. (explain)

Radeon HD 6870 50400 Mtexels/sec
GeForce GTX 560 45360 Mtexels/sec
Difference: 5040 (11%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 6870 is superior to the GeForce GTX 560, but not by far. (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: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units 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 maximum amount of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum 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:

SP33D

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
