GeForce GTX 460 150 Watts
Difference: 34 Watts (29%)

Memory Bandwidth

In theory, the GeForce GTX 550 Ti is 14% faster than the GeForce GTX 460 in general, because of its greater bandwidth. (explain)

GeForce GTX 550 Ti 98496 MB/sec
GeForce GTX 460 86400 MB/sec
Difference: 12096 (14%)

Texel Rate

The GeForce GTX 460 should be much (about 31%) better at anisotropic filtering than the GeForce GTX 550 Ti. (explain)

GeForce GTX 460 37800 Mtexels/sec
GeForce GTX 550 Ti 28800 Mtexels/sec
Difference: 9000 (31%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 550 Ti is a better choice, and very much so. (explain)

GeForce GTX 550 Ti 21600 Mpixels/sec
GeForce GTX 460 16200 Mpixels/sec
Difference: 5400 (33%)

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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.

Nick says:

It seems that the 550 Ti uses a third less power and beats the 460 2 out of 3 catagories. Less cores but greater performance, 550 Ti is the winner.

Jack says:

Nope your wrong GTX 460 is more powerfull

Frank says:

Nope, you're both wrong. Intel HD is the king.

Frank says:

This comparison is done with the weaker 768mb GTX 460...

Not the standard one with 1024mb 256bit memory at 115200 MB/sec.

jajaja intel hd

Intel says:

Intel HD FTW! HAHAHAHA!

Man says:

Intel HD is the absolute pinnacle of performance. Definitely Intel HD for the win.

Johnny says:

Intel hd? Kkkkk... 550Ti win! In this comparation (: but..

thaghost says:

I only wish I could afford something with Intel HD, It's some top of the line stuff.

Assassin says:

Intel HD is effective but not as much as GTX 550 ti It has only one thing less which is Texel rate & due to less power cosumption it wins...

Jax says:

Lol intel HD.... That's so funny
