Radeon HD 4850 2GB vs Radeon R5 M330

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon HD 4850 2GB should be quite a bit faster than the Radeon R5 M330 in general. (explain)

Radeon HD 4850 2GB		63552 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 49152 (341%)

Texel Rate

The Radeon HD 4850 2GB should be much (more or less 21%) more effective at anisotropic filtering than the Radeon R5 M330. (explain)

Radeon HD 4850 2GB		25000 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 4400 (21%)

Pixel Rate

The Radeon HD 4850 2GB is a lot (about 21%) faster with regards to full screen anti-aliasing than the Radeon R5 M330, and also should be capable of handling higher screen resolutions better. (explain)

Radeon HD 4850 2GB		10000 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 1760 (21%)

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 transferred over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum 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 clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
