GeForce GTX 560 Ti 448 vs Radeon HD 6870

Intro

The GeForce GTX 560 Ti 448 uses a 40 nm design. nVidia has clocked the core speed at 732 MHz. The GDDR5 RAM is set to run at a speed of 900 MHz on this specific card. It features 448 SPUs as well as 56 Texture Address Units and 40 ROPs.

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

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 can be applied in one second. This figure is calculated by multiplying the total number 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.

which graphic card should i use for gaming such crysis 2 running in a very high setting?

Diogo says:

Get the HD 6870 Dual Fan
and then make a little overclock !

Hd 6870 is better than gtx 560 ti, because its cheaper than gtx 560 ti... Amd also make some features that in compatible to the nvidia graphic cards

SmileMan says:

the gtx560ti and the 448 version are better in games, better avg fps. HD6870 is better in performance, if AMD updated their drivers --> hd6870 would own this 2. But nvidea got superior drivers, so they can make more results with less performance. So if amd had drivers updated like that...

Then would they be the master with a big lead!
