GeForce GTX 650 Ti 2GB vs Radeon R9 M380

Intro

The GeForce GTX 650 Ti 2GB has core clock speeds of 928 MHz on the GPU, and 1350 MHz on the 2048 MB of GDDR5 RAM. It features 768 SPUs as well as 64 Texture Address Units and 16 ROPs.

Compare those specifications to the Radeon R9 M380, which comes with a GPU core clock speed of 1000 MHz, and 4096 MB of GDDR5 RAM running at 1500 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M380 should in theory be just a 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 is much (more or less 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 resolution is important to you, then the Radeon R9 M380 is superior to the GeForce GTX 650 Ti 2GB, but not by far. (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 (measured in MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
