GeForce GTX 660 vs GeForce GTX 660 Ti
Intro
The GeForce GTX 660 uses a 28 nm design. nVidia has clocked the core speed at 980 MHz. The GDDR5 memory works at a speed of 1502 MHz on this particular card. It features 960 SPUs along with 80 TAUs and 24 Rasterization Operator Units.Compare those specs to the GeForce GTX 660 Ti, which has clock speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 RAM. It features 1344 SPUs along with 112 Texture Address Units and 24 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.

Just bought non Ti version
Is it worth buying non ti? like i don't care how much they cost i want the best one, which one is it of those 2?
I'm getting the non Ti. That 31% isn't worth another $100.
fuck u devesh
msg2short
Which can I choose?
Easy choice, definitely 660 Ti, runs much better than what it says in the review, everyone, go for the TI version
Take non Ti cards, don't pay more, dudes
Simply,even compared to GTX 670 take the GTX 660 instead!
GTX 660 costs about 200$+ and is just about 30-40% slover than a GTX 670 which cost 400$...
You will not see difference if you don't have problems with FPS...
Man just buy Ati radeon hd 7870 this is very cheap and better than both gtx 660 and ti
sheraz
if we want to use ATi radeon 7870 we need amd motherboard cause this card has crossfire technology which is you can only use on amd motherboards
Shoaib watch this video u will see how to install this card
in this video he have intel motherboard so u are wrong u can install this card on intel motherboard
u can install it on intel motherboard . crossfire means AMD multi GPU setup
I am dealor of 3D cards and wana share that GTX 660 ti is bettet than GTX 660 at very small value.So if any one wana know which is best i know a lot better than u guys
so prefer 660 Ti if there is no problum of money
Mr sheraz says HD 7870 is much cheaper than 660 660 ti,bro this card is about 370 dollers and the GTX 660 ti is about 275 dollers so what in a God name is the HD 7870 cheaper than Gtx 660 and 660 ti
Dont talk if u dont know about prises
@John Lerages,
Don't talk about what you do or do not know when you can't even speak english. Get a life and don't go dissing other people MR "Better than you guys" You seem like a tosspot nub.
lol , ahaha , chill
Fight Fight Fight
i am from russia komunizm says me to buy ti
