GeForce GTX 650 Ti vs Radeon HD 5750 1GB

Intro

The GeForce GTX 650 Ti features a GPU clock speed of 928 MHz, and the 1024 MB of GDDR5 memory is set to run at 1350 MHz through a 128-bit bus. It also is made up of 768 SPUs, 64 Texture Address Units, and 16 ROPs.

Compare all that to the Radeon HD 5750 1GB, which comes with a clock frequency of 700 MHz and a GDDR5 memory frequency of 1150 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It features 720(144x5) SPUs, 36 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.

The ATI 5750 was a pretty good card My friend had one in is i7 870
Now has a ATI 7770.

But it seemed to play games as well as my old 5850 did. Goes to show you do not need expensive for high end gaming.
