GeForce GTX 465 vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which comes with a clock speed of 1030 MHz and a DDR3 memory frequency of 900 MHz. It also uses a 64-bit bus, and uses a 28 nm design. It is comprised of 320 SPUs, 20 Texture Address Units, and 8 Raster Operation Units.

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 465 is superior to the Radeon R5 M330, by far. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 11184 (136%)

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 max amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, 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 most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs 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 fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
