GeForce GTX 465 vs Radeon R5 M230

Intro

Compare those specifications to the Radeon R5 M230, which makes use of a 28 nm design. AMD has set the core frequency at 780 MHz. The DDR3 memory runs at a speed of 1000 MHz on this card. It features 320 SPUs as well as 20 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 465 should be quite a bit faster than the Radeon R5 M230 overall. (explain)

GeForce GTX 465		102592 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 86592 (541%)

Texel Rate

The GeForce GTX 465 will be much (more or less 71%) more effective at texture filtering than the Radeon R5 M230. (explain)

GeForce GTX 465		26708 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 11108 (71%)

Pixel Rate

The GeForce GTX 465 should be much (about 523%) more effective at AA than the Radeon R5 M230, and will be capable of handling higher resolutions better. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 16304 (523%)

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: Bandwidth is the max amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
