GeForce GTX 550 Ti vs GeForce GTX 750 Ti


Intro

The GeForce GTX 550 Ti makes use of a 40 nm design. nVidia has set the core speed at 900 MHz. The GDDR5 RAM is set to run at a speed of 1026 MHz on this card. It features 192 SPUs as well as 32 TAUs and 24 ROPs.

Compare that to the GeForce GTX 750 Ti, which uses a 28 nm design. nVidia has set the core speed at 1020 MHz. The GDDR5 memory runs at a speed of 1350 MHz on this particular card. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.

This comparison is rather misleading as the 750's real-life performance is much better than the 550. Weird.

Gabriel says:

I thought so too, even the price of gtx 750 TI is higher, I really don't get it

Matheus says:

This compraison is a quite wrong.
750ti is really faster than 550ti.

Matheus says:

750ti is really faster than 550ti.

Мачо says:

Сижу на 550Ti и пока не вижу смысла переходить с этого ценового диапазона.

Alex says:

I want to believe, the 750 is equal to 550.

Gary To says:

750ti is almost double the 550ti's performance

Redx says:

LoL, its quite wrong.. the gtx750Ti is faster than gtx550ti

Spike says:

would you believe at this time amazon and other sites want 500$ for a 550 ti and only 150$ or so for the 750? must be an ANTIQUE in their eyes... that's just sad...

Razvan says:

Yes, 550ti is better than 750 ti in some cases! I had MSI Geforce N550GTX-TI Cyclone II 1GD5/OC and
ASUS GeForce GTX 750 Ti 2GB DDR5 128-bit.......its weird but its true.

truthspeak says:

the evidence speaks for its self the 550 ti is the best gpu here
