GeForce GTX 465 vs Radeon R5 M230

Intro

Compare those specs to the Radeon R5 M230, which features a core clock speed of 780 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 64-bit memory bus, and makes use of a 28 nm design. It is made up of 320 SPUs, 20 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 465 will be 541% quicker than the Radeon R5 M230 overall, due to its greater bandwidth. (explain)

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

Texel Rate

The GeForce GTX 465 is much (approximately 71%) more effective at AF than the Radeon R5 M230. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 465 is a better choice, by far. (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 largest amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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