GeForce GTX 650 Ti vs Radeon R9 M380

Intro

The GeForce GTX 650 Ti makes use of a 28 nm design. nVidia has clocked the core frequency at 928 MHz. The GDDR5 RAM is set to run at a frequency of 1350 MHz on this particular model. It features 768 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Compare all that to the Radeon R9 M380, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 RAM runs at a frequency of 1500 MHz on this specific model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M380 should theoretically perform just a bit faster than the GeForce GTX 650 Ti in general. (explain)

Radeon R9 M380 96000 MB/sec
GeForce GTX 650 Ti 86400 MB/sec
Difference: 9600 (11%)

Texel Rate

The GeForce GTX 650 Ti will be a lot (approximately 48%) faster with regards to anisotropic filtering than the Radeon R9 M380. (explain)

GeForce GTX 650 Ti 59392 Mtexels/sec
Radeon R9 M380 40000 Mtexels/sec
Difference: 19392 (48%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M380 is a better choice, but only just. (explain)

Radeon R9 M380 16000 Mpixels/sec
GeForce GTX 650 Ti 14848 Mpixels/sec
Difference: 1152 (8%)

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 maximum amount of information (counted in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high 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 texture units by the core speed of the chip. The higher this number, the better the video 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 amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. 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 is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
