GeForce GTX 650 Ti vs Radeon R9 M380

Intro

Compare those specifications to the Radeon R9 M380, which has core speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M380 should in theory be a bit better than the GeForce GTX 650 Ti overall. (explain)

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

Texel Rate

The GeForce GTX 650 Ti should be quite a bit (about 48%) more effective at AF than the Radeon R9 M380. (explain)

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

Pixel Rate

The Radeon R9 M380 should be just a bit (approximately 8%) more effective at anti-aliasing than the GeForce GTX 650 Ti, and also will be capable of handling higher resolutions while still performing well. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
