GeForce GTX 285 1GB vs Radeon R5 M330

Intro

Compare all that to the Radeon R5 M330, which uses a 28 nm design. AMD has set the core frequency at 1030 MHz. The DDR3 RAM is set to run at a speed of 900 MHz on this card. It features 320 SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

Radeon R5 M330		14400 MB/sec
	Difference: 144576 (1004%)

Texel Rate

The GeForce GTX 285 1GB should be a lot (approximately 152%) better at AF than the Radeon R5 M330. (explain)

GeForce GTX 285 1GB		51840 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 31240 (152%)

Pixel Rate

The GeForce GTX 285 1GB is much (about 152%) better at anti-aliasing than the Radeon R5 M330, and will be capable of handling higher screen resolutions better. (explain)

GeForce GTX 285 1GB		20736 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 12496 (152%)

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 maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 most pixels the graphics card can possibly write 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 core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
