GeForce GTX 560 vs Radeon HD 6870

Intro

The GeForce GTX 560 makes use of a 40 nm design. nVidia has set the core speed at 810 MHz. The GDDR5 RAM is set to run at a frequency of 1001 MHz on this particular card. It features 336 SPUs as well as 56 Texture Address Units and 32 ROPs.

Compare all of that to the Radeon HD 6870, which has clock speeds of 900 MHz on the GPU, and 1050 MHz on the 1024 MB of GDDR5 RAM. It features 1120 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.

(No game benchmarks for this combination yet.)

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

The Radeon HD 6870 should in theory be a bit faster than the GeForce GTX 560 overall. (explain)

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

Texel Rate

The Radeon HD 6870 should be a little bit (about 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

The Radeon HD 6870 will be a small bit (about 11%) faster with regards to FSAA than the GeForce GTX 560, and should be capable of handling higher screen resolutions without slowing down too much. (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 maximum amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to 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.

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!
