GeForce GTX 650 Ti vs GeForce GTX 750 Ti

Intro

The GeForce GTX 650 Ti comes with core 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 ROPs.

Compare those specs to the GeForce GTX 750 Ti, which has GPU clock speed of 1020 MHz, and 2048 MB of GDDR5 RAM set to run at 1350 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 16 ROPs.

GeForce GTX 750 Ti 60 Watts
GeForce GTX 650 Ti 110 Watts
Difference: 50 Watts (83%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce GTX 650 Ti is a lot (more or less 46%) better at anisotropic filtering than the GeForce GTX 750 Ti. (explain)

GeForce GTX 650 Ti 59392 Mtexels/sec
GeForce GTX 750 Ti 40800 Mtexels/sec
Difference: 18592 (46%)

Pixel Rate

The GeForce GTX 750 Ti is a bit (approximately 10%) faster with regards to AA than the GeForce GTX 650 Ti, and also will be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 750 Ti 16320 Mpixels/sec
GeForce GTX 650 Ti 14848 Mpixels/sec
Difference: 1472 (10%)

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 maximum amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 can be applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.

George says:

Is the 750Ti's Texture Rate really that much lower than the 650Ti's Texture Rate? If so how is this a improvement? I only see early benchmarks of the 650Ti vs the recent 750Ti benchmarks They need to redo the 650Ti benchmarks to get a more accurate performance comparison, Everyone knows most of the 600 series had problems with early drivers. Any idiot knows higher text = higher FPS

Auris says:

What the hell? you should re do 750ti stats, because they can not be bad as this.
