Radeon HD 6450 (OEM) 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 runs at a frequency of 900 MHz on this specific card. It features 320 SPUs as well as 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R5 M330, in theory, should be just a bit faster than the Radeon HD 6450 (OEM) in general. (explain)

Radeon R5 M330		14400 MB/sec
Radeon HD 6450 (OEM)		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The Radeon R5 M330 should be a lot (more or less 312%) faster with regards to anisotropic filtering than the Radeon HD 6450 (OEM). (explain)

Radeon R5 M330		20600 Mtexels/sec
Radeon HD 6450 (OEM)		5000 Mtexels/sec
	Difference: 15600 (312%)

Pixel Rate

The Radeon R5 M330 should be quite a bit (about 230%) better at AA than the Radeon HD 6450 (OEM), and able to handle higher screen resolutions more effectively. (explain)

Radeon R5 M330		8240 Mpixels/sec
Radeon HD 6450 (OEM)		2500 Mpixels/sec
	Difference: 5740 (230%)

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 data (counted in MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
