GeForce GTX 650 Ti 2GB vs Radeon R5 M230

Intro

Compare all that to the Radeon R5 M230, which has GPU clock speed of 780 MHz, and 2048 MB of DDR3 RAM set to run at 1000 MHz through a 64-bit bus. It also features 320 SPUs, 20 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 650 Ti 2GB should in theory be a lot faster than the Radeon R5 M230 in general. (explain)

GeForce GTX 650 Ti 2GB		86400 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 70400 (440%)

Texel Rate

The GeForce GTX 650 Ti 2GB is quite a bit (more or less 281%) faster with regards to anisotropic filtering than the Radeon R5 M230. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 43792 (281%)

Pixel Rate

The GeForce GTX 650 Ti 2GB is much (more or less 376%) faster with regards to FSAA than the Radeon R5 M230, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 11728 (376%)

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 largest amount of information (in units of MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
