GeForce GTX 650 Ti 2GB vs Radeon R9 M380

Intro

The GeForce GTX 650 Ti 2GB uses a 28 nm design. nVidia has set the core speed at 928 MHz. The GDDR5 RAM is set to run at a speed of 1350 MHz on this card. It features 768 SPUs along with 64 TAUs and 16 ROPs.

Compare that to the Radeon R9 M380, which comes with a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M380 should in theory be a little bit superior to the GeForce GTX 650 Ti 2GB overall. (explain)

Radeon R9 M380 96000 MB/sec
GeForce GTX 650 Ti 2GB 86400 MB/sec
Difference: 9600 (11%)

Texel Rate

The GeForce GTX 650 Ti 2GB should be quite a bit (approximately 48%) more effective at texture filtering than the Radeon R9 M380. (explain)

GeForce GTX 650 Ti 2GB 59392 Mtexels/sec
Radeon R9 M380 40000 Mtexels/sec
Difference: 19392 (48%)

Pixel Rate

The Radeon R9 M380 will be just a bit (about 8%) better at anti-aliasing than the GeForce GTX 650 Ti 2GB, and also able to handle higher screen resolutions better. (explain)

Radeon R9 M380 16000 Mpixels/sec
GeForce GTX 650 Ti 2GB 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: Bandwidth is the maximum amount of information (measured in MB 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 its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
