Radeon HD 5770 vs Radeon HD 7750
Intro
The Radeon HD 5770 has a clock frequency of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It features 800(160x5) SPUs, 40 TAUs, and 16 Raster Operation Units.Compare those specs to the Radeon HD 7750, which has core clock speeds of 800 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 memory. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units of the card 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 per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number 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 drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.

3 Responses to “Radeon HD 5770 vs Radeon HD 7750”Wow 2xof pconsum and a few difference of perfor
Yeah but the 5770 came out in 2009!! let's just put it that way, the 7750 is not a card to recommend to anyone willing to play something decent. Better spending a little more for a 7770 or better.
In games (fps) 7750 = 5770.
Ciao
