GeForce GTX 560 vs Radeon HD 6870

Intro

The GeForce GTX 560 makes use of a 40 nm design. nVidia has clocked the core frequency at 810 MHz. The GDDR5 RAM is set to run at a speed of 1001 MHz on this model. It features 336 SPUs along with 56 TAUs and 32 ROPs.

Compare those specifications to the Radeon HD 6870, which features a GPU core clock speed of 900 MHz, and 1024 MB of GDDR5 memory set to run at 1050 MHz through a 256-bit bus. It also is made up of 1120 Stream Processors, 56 TAUs, and 32 ROPs.

(No game benchmarks for this combination yet.)

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential 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.

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!
