GeForce GTX 750 Ti vs Radeon R9 270

Intro

The GeForce GTX 750 Ti makes use of a 28 nm design. nVidia has set the core speed at 1020 MHz. The GDDR5 memory works at a frequency of 1350 MHz on this particular model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Compare those specs to the Radeon R9 270, which makes use of a 28 nm design. AMD has set the core speed at 900 MHz. The GDDR5 RAM is set to run at a frequency of 1400 MHz on this card. It features 1280 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.

GeForce GTX 750 Ti 60 Watts
Radeon R9 270 150 Watts
Difference: 90 Watts (150%)

Memory Bandwidth

As far as performance goes, the Radeon R9 270 should in theory be quite a bit better than the GeForce GTX 750 Ti in general. (explain)

Radeon R9 270 179200 MB/sec
GeForce GTX 750 Ti 86400 MB/sec
Difference: 92800 (107%)

Texel Rate

The Radeon R9 270 should be much (about 76%) faster with regards to AF than the GeForce GTX 750 Ti. (explain)

Radeon R9 270 72000 Mtexels/sec
GeForce GTX 750 Ti 40800 Mtexels/sec
Difference: 31200 (76%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 270 is a better choice, by far. (explain)

Radeon R9 270 28800 Mpixels/sec
GeForce GTX 750 Ti 16320 Mpixels/sec
Difference: 12480 (76%)

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: Memory bandwidth is the max 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 card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount 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 also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.

This is no comparison. The R9 270 is a high end card. The 750 Ti is a Entry level card.
NVIDIA SUCKS says:
I HAD A GTX 750 Ti AND A GTX 760 BY PNY DIE ON ME AMD FTW
ItsTheGamerEdit says:
AMD fanboys...
Ahem.
GTX 750 Ti is NOT an entry level Graphics card. R9 270 is in the middle-high end level so this is pointless.
Anders says:
They both cost $150, so not a pointless comparision.
Shane says:
The r9 270/270x used to cost around the $300 before the huge bitcoin/litecoin rush, so after the inflation of AMD card prices, they dropped considerably, placing the r9 270 to about $170 range. So yes, it is a pointless comparison.
Josh says:
And yet I purchased my r9 270 for about 150. As the price point stands now, the only pointless part of the comparison is that the 750ti is pointless. For pretty close to the exact same price you can get double the performance.
El_Lobo says:
I am worried about the extra heat generated by the AMD card (150 vs. 60 Watts). What does this say about longevity and how does this affect the rest of the computer's components?
