GeForce GTX 550 Ti vs GeForce GTX 560

Intro

Compare those specifications to the GeForce GTX 560, which comes with a GPU core clock speed of 810 MHz, and 1024 MB of GDDR5 memory running at 1001 MHz through a 256-bit bus. It also is comprised of 336 SPUs, 56 Texture Address Units, and 32 ROPs.

GeForce GTX 550 Ti		98496 MB/sec
	Difference: 29632 (30%)

Texel Rate

The GeForce GTX 560 will be much (about 58%) more effective at texture filtering than the GeForce GTX 550 Ti. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 16560 (58%)

Pixel Rate

The GeForce GTX 560 is a little bit (more or less 20%) faster with regards to anti-aliasing than the GeForce GTX 550 Ti, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GTX 550 Ti		21600 Mpixels/sec
	Difference: 4320 (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.

Price Comparison

Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card 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 Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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.
