GeForce 9800 GTX+ vs Radeon HD 5770
Intro
The GeForce 9800 GTX+ has a clock speed of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also uses a 256-bit bus, and makes use of a 55 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 16 ROPs.Compare all of that to the Radeon HD 5770, which uses a 40 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 memory is set to run at a frequency of 1200 MHz on this particular model. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.

2 Responses to “GeForce 9800 GTX+ vs Radeon HD 5770”[...] twice as good. It performs smilarly (5% better overall) than a 5770, which is about overall about 15% better than a 9800GTX. The 550 is a pretty low end card, better yes, twice as good - definitely no. [...]
Actually according to Textural rate the 9800GTX+ beats the 5770. If the 2 cards were tested at lower resolution like 1280x1024 the 9800 GTX+ would take it in fps in almost all games above. And if you have a 17inch monitor thats the highest res you can go anyway.
