GeForce GTX 560 Ti 448 vs Radeon HD 7850


Intro

The GeForce GTX 560 Ti 448 makes use of a 40 nm design. nVidia has set the core frequency at 732 MHz. The GDDR5 memory runs at a frequency of 900 MHz on this particular model. It features 448 SPUs as well as 56 TAUs and 40 ROPs.

Compare those specifications to the Radeon HD 7850, which features a GPU core clock speed of 860 MHz, and 2048 MB of GDDR5 RAM set to run at 1200 MHz through a 256-bit bus. It also features 1024 Stream Processors, 64 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.

Zotac GTX 560 TI 448 or GIGABYTE HD7850 - Hardware Canucks says:

[...] Definitely the HD 7850 ( OC'd to 975mhz) would be a better choice because it has the new 28nm architecture, powerfull (compared to GTX560 TI) n stuff ( 2GB RAM and consumes less power ) Check this site out for more performance comparisons...
