GeForce GTX 550 Ti vs GeForce GTX 750 Ti


Intro

The GeForce GTX 550 Ti makes use of a 40 nm design. nVidia has clocked the core speed at 900 MHz. The GDDR5 memory works at a speed of 1026 MHz on this particular card. It features 192 SPUs as well as 32 TAUs and 24 Rasterization Operator Units.

Compare those specs to the GeForce GTX 750 Ti, which features a core clock frequency of 1020 MHz and a GDDR5 memory speed of 1350 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max 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
