GeForce GTX 560 Ti 448 vs Radeon HD 7850


Intro

The GeForce GTX 560 Ti 448 comes with a core clock frequency of 732 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 320-bit memory bus, and makes use of a 40 nm design. It is comprised of 448 SPUs, 56 TAUs, and 40 ROPs.

Compare that to the Radeon HD 7850, which makes use of a 28 nm design. AMD has set the core frequency at 860 MHz. The GDDR5 RAM runs at a speed of 1200 MHz on this particular model. It features 1024 SPUs as well as 64 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach 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...
