Geforce GTX 760 vs Radeon R9 270

Intro

The Geforce GTX 760 comes with a GPU core clock speed of 980 MHz, and the 2048 MB of GDDR5 RAM runs at 1502 MHz through a 256-bit bus. It also features 1152 SPUs, 96 Texture Address Units, and 32 ROPs.

Compare those specifications to the Radeon R9 270, which uses a 28 nm design. AMD has clocked the core speed at 900 MHz. The GDDR5 memory works at a frequency of 1400 MHz on this specific card. It features 1280 SPUs as well as 80 TAUs and 32 ROPs.

Radeon R9 270 150 Watts
Geforce GTX 760 170 Watts
Difference: 20 Watts (13%)

Memory Bandwidth

In theory, the Geforce GTX 760 is 7% faster than the Radeon R9 270 overall, due to its greater data rate. (explain)

Geforce GTX 760 192256 MB/sec
Radeon R9 270 179200 MB/sec
Difference: 13056 (7%)

Texel Rate

The Geforce GTX 760 will be much (about 31%) better at texture filtering than the Radeon R9 270. (explain)

Geforce GTX 760 94080 Mtexels/sec
Radeon R9 270 72000 Mtexels/sec
Difference: 22080 (31%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Geforce GTX 760 is a better choice, but only just. (explain)

Geforce GTX 760 31360 Mpixels/sec
Radeon R9 270 28800 Mpixels/sec
Difference: 2560 (9%)

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 largest amount of information (counted in MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one 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 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 fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.

Wow... price-to-performance on the Nvidia card is absolutely pathetic.

Guess you're paying for the brand.

rodrigues says:

nvidia no more. It Dosn't worth the difference of prices.

john says:

270 card performs the same and there is no real noticeable differnce on a 24inch 1080p 120 ghz screen-

price i go with r9 and its dx12 compatible

Ruru says:

The cards costs the same right now and Nvidia is the better choice.
