Radeon HD 5770 vs Radeon R5 M330

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 5770 should theoretically be quite a bit faster than the Radeon R5 M330 in general. (explain)

Radeon HD 5770		76800 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 62400 (433%)

Texel Rate

The Radeon HD 5770 is a lot (more or less 65%) more effective at texture filtering than the Radeon R5 M330. (explain)

Radeon HD 5770		34000 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 13400 (65%)

Pixel Rate

The Radeon HD 5770 is much (approximately 65%) more effective at AA than the Radeon R5 M330, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon HD 5770		13600 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 5360 (65%)

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 max amount of information (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 rate also depends on quite a few 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.
