Radeon HD 4550 256MB vs Radeon R5 M330

Intro

The Radeon HD 4550 256MB comes with a GPU core speed of 600 MHz, and the 256 MB of DDR3 RAM runs at 800 MHz through a 64-bit bus. It also is comprised of 80(16x5) Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.

Compare those specifications to the Radeon R5 M330, which features a GPU core clock speed of 1030 MHz, and 2048 MB of DDR3 memory set to run at 900 MHz through a 64-bit bus. It also is made up of 320 Stream Processors, 20 Texture Address Units, and 8 Raster Operation Units.

Radeon R5 M330 14400 MB/sec
Radeon HD 4550 256MB 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The Radeon R5 M330 will be a lot (about 329%) faster with regards to AF than the Radeon HD 4550 256MB. (explain)

Radeon R5 M330 20600 Mtexels/sec
Radeon HD 4550 256MB 4800 Mtexels/sec
Difference: 15800 (329%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R5 M330 is superior to the Radeon HD 4550 256MB, by a large margin. (explain)

Radeon R5 M330 8240 Mpixels/sec
Radeon HD 4550 256MB 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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
