GeForce GTX 650 vs GeForce GTX 650 Ti

Intro

The GeForce GTX 650 uses a 28 nm design. nVidia has clocked the core speed at 1058 MHz. The GDDR5 RAM works at a speed of 1250 MHz on this specific model. It features 384 SPUs as well as 32 TAUs and 16 ROPs.

Compare those specifications to the GeForce GTX 650 Ti, which features clock speeds of 928 MHz on the GPU, and 1350 MHz on the 1024 MB of GDDR5 memory. It features 768 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card 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 processed in a second.

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

Dane says:

The GTX650 and ti are nearly the same. Only unified shaders is the difference. But both are good cards i say. I love Nvidia.

Ankit says:

Should i sell my gtx 650 2gb and buy a gtx 650 ti 2gb help

Brian says:

@Ankit

No you shouldn't, its not that big of a difference. You are better off overclocking your card.

shingo says:

yo tengo la gtx650 y es una maravilla y solo me costo 1070 pesos mexicanos marca gigabye yeaaa

johnbbdog says:

Its all about texture filtering for me.

ccc says:

gtx 650 OC vs gtx 650 Ti
all 1 Gb

armin2100 says:

650gtx=2gb and 650 gtx ti=1gb
so which one is better? how do you say they are same?please help me.i want to choose one of them.help me!

reply-to-armin2100 says:

armin2100: This site is a computer-generated comparison between the two cards. It has (supposedly quite automatically) picked a version of the GTX with 2GB memory, and GTX-TI with 1GB memory. Both cards are sold with 1GB and 2GB memory, check your dealer or do a single Google search.

Paulus says:

hello i just wanna ask some question, i wanna buy one of these 2 card, but my OS is only Core i3, is that enough to support these cards?
some friend told me that if i want to use one of these cards, i should at least have Core i5 in my boot.
any suggestion? thanks anyway.

Azis says:

@Paulus
There is no such thing as a core i3 OS, that's a CPU

Your friend is saying bullshit, you can run it on any cpu, it all depends on the motherboard, but it's probably compatible.
