GeForce GTX 570 vs Radeon HD 6950 2GB

Intro

The GeForce GTX 570 makes use of a 40 nm design. nVidia has clocked the core frequency at 732 MHz. The GDDR5 memory works at a frequency of 950 MHz on this model. It features 480 SPUs as well as 60 Texture Address Units and 40 ROPs.

Compare those specs to the Radeon HD 6950 2GB, which has GPU clock speed of 800 MHz, and 2048 MB of GDDR5 RAM set to run at 1250 MHz through a 256-bit bus. It also features 1408 Stream Processors, 88 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, 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 most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.

These benchmarks are poor. I get better average frames with my 6950 in these games (roughly 10 more in each)

In 3dsmax viewport rendering. GTX570 is poor performance. HD6950 is very smooth performance !
