GeForce GTX 750 Ti vs Radeon HD 5770

Intro

The GeForce GTX 750 Ti uses a 28 nm design. nVidia has set the core speed at 1020 MHz. The GDDR5 RAM is set to run at a frequency of 1350 MHz on this model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the Radeon HD 5770, which features a clock speed of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is made up of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti 60 Watts
Radeon HD 5770 108 Watts
Difference: 48 Watts (80%)

Memory Bandwidth

In theory, the GeForce GTX 750 Ti will be 13% quicker than the Radeon HD 5770 in general, because of its higher data rate. (explain)

GeForce GTX 750 Ti 86400 MB/sec
Radeon HD 5770 76800 MB/sec
Difference: 9600 (13%)

Texel Rate

The GeForce GTX 750 Ti will be just a bit (more or less 20%) faster with regards to AF than the Radeon HD 5770. (explain)

GeForce GTX 750 Ti 40800 Mtexels/sec
Radeon HD 5770 34000 Mtexels/sec
Difference: 6800 (20%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 750 Ti is the winner, but only just. (explain)

GeForce GTX 750 Ti 16320 Mpixels/sec
Radeon HD 5770 13600 Mpixels/sec
Difference: 2720 (20%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 can be applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling 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 that the graphics chip can possibly record to its 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 card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.

Yes of course VISHWAS
I tested it already.
