GeForce GTX 650 Ti 2GB vs Radeon R9 M380

Intro

The GeForce GTX 650 Ti 2GB comes with core clock speeds of 928 MHz on the GPU, and 1350 MHz on the 2048 MB of GDDR5 memory. It features 768 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Compare those specs to the Radeon R9 M380, which comes with clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M380 should theoretically be just a bit better than 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 is much (approximately 48%) better 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

If running with a high screen resolution is important to you, then the Radeon R9 M380 is the winner, but it probably won't make a huge difference. (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 largest amount of information (in units of 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. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
