GeForce GTX 550 Ti vs GeForce GTX 650


The GeForce GTX 550 Ti comes with a GPU core speed of 900 MHz, and the 1024 MB of GDDR5 RAM runs at 1026 MHz through a 192-bit bus. It also is made up of 192 SPUs, 32 Texture Address Units, and 24 ROPs.

Compare those specifications to the GeForce GTX 650, which uses a 28 nm design. nVidia has clocked the core frequency at 1058 MHz. The GDDR5 memory is set to run at a speed of 1250 MHz on this specific model. It features 384 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

GeForce GTX 650 33856 Mtexels/sec
GeForce GTX 550 Ti 28800 Mtexels/sec
Difference: 5056 (18%)

Pixel Rate

The GeForce GTX 550 Ti is quite a bit (about 28%) better at FSAA than the GeForce GTX 650, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 550 Ti 21600 Mpixels/sec
GeForce GTX 650 16928 Mpixels/sec
Difference: 4672 (28%)

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 max amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should 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 in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.

Rcoil says:

I'm not sure about the increase of the performance from the GTX 550 Ti to GTX 650

Med Ali says:

even for me increase of performances between the 650 and 550ti are only in the Unified Shaders and the texel rate.

Rcoil says:

If you look at the following link just a little bit different. and even then only in synthetic benchmarks. not the real game.

Kirvic says:

Hi, what about video edition, which one is better to work for example in Adobe Premiere Pro CS6? or After Effects?


If you note, the power consumption of 650 is lower than the 550 ti, so you dont have to buy a great energy source!

jhon says:

gtx550ti has pci 2.0 and its 1gb its power consumation is higher .while gtx65 has 3.0 pci and its 2gb and power consumation is lower. if u really want to buy 192bits then it is better to buy 256bits.

Hannes says:

550ti is better for me texel memorry and pixel rate Hannes

edin says:

i play all games with high AF on my HD 6670 1gb ddr5, but i cant play new games on 1080p,only low to medium detail and off Anti Alaising, so beter card is the one that can play 1080p without lag, in this case gtx 550ti with bigger pixel rate

tarun says:

but gtx 650 can give good gaming performance than gtx 550ti

john says:

yes GTX 650 GDDR5 is 20% faster than GTX 550TI GTX 650 run with 64 W but GTX 550 ti need 116W so low power high performance
