GeForce GTX 280 vs Radeon R5 M330

Intro

Compare that to the Radeon R5 M330, which features core speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 280 is 884% quicker than the Radeon R5 M330 overall, due to its greater data rate. (explain)

GeForce GTX 280		141696 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 127296 (884%)

Texel Rate

The GeForce GTX 280 will be much (approximately 134%) better at AF than the Radeon R5 M330. (explain)

GeForce GTX 280		48160 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 27560 (134%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 280 is the winner, and very much so. (explain)

GeForce GTX 280		19264 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 11024 (134%)

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 information (counted in MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better 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 amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
