GeForce 9800 GTX+ vs Radeon HD 5770
Intro
The GeForce 9800 GTX+ has a GPU core speed of 738 MHz, and the 512 MB of GDDR3 RAM runs at 1100 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 64 TAUs, and 16 Raster Operation Units.Compare that to the Radeon HD 5770, which makes use of a 40 nm design. AMD has set the core speed at 850 MHz. The GDDR5 RAM works at a frequency of 1200 MHz on this model. It features 800(160x5) SPUs along with 40 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes 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, especially 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.
