VS

GeForce GTX 550 Ti vs Radeon HD 6670 (OEM)

Intro

The GeForce GTX 550 Ti uses a 40 nm design. nVidia has set the core speed at 900 MHz. The GDDR5 memory works at a speed of 1026 MHz on this model. It features 192 SPUs as well as 32 Texture Address Units and 24 ROPs.

Compare all that to the Radeon HD 6670 (OEM), which comes with a clock speed of 800 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is comprised of 480 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 are processed in one second. This number is worked out by multiplying the total 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 in a second.

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

OFC. Nvidia 550 Ti... but an additional 40-50 $ expense for a good smps to provide it with the required power. Where as Raedon would run smooth with you regular smps

creio eu maior coisa dai é dinheiro eu fico com hd 6770 ela está 250 R$ ela é boa ai gtx 550ti 370 R$ 120 R$ de difrença pra quem que roda no full com hd 6670 da pra roda de boa recomendo hd 6670 ela boa pode ter certeza
