Radeon HD 4550 512MB vs Radeon R5 M330

Intro

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

Radeon HD 4550 512MB		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The Radeon R5 M330 will be quite a bit (approximately 329%) more effective at texture filtering than the Radeon HD 4550 512MB. (explain)

Radeon R5 M330		20600 Mtexels/sec
Radeon HD 4550 512MB		4800 Mtexels/sec
	Difference: 15800 (329%)

Pixel Rate

The Radeon R5 M330 is quite a bit (approximately 243%) faster with regards to FSAA than the Radeon HD 4550 512MB, and also should be able to handle higher screen resolutions more effectively. (explain)

Radeon R5 M330		8240 Mpixels/sec
Radeon HD 4550 512MB		2400 Mpixels/sec
	Difference: 5840 (243%)

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 (counted in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could 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 ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
