Radeon HD 5550 vs Radeon R7 370 2G

Intro

Compare that to the Radeon R7 370 2G, which makes use of a 28 nm design. AMD has clocked the core speed at 975 MHz. The GDDR5 RAM works at a frequency of 1400 MHz on this particular model. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 370 2G should in theory be quite a bit faster than the Radeon HD 5550 in general. (explain)

Radeon R7 370 2G		179200 MB/sec
Radeon HD 5550		12800 MB/sec
	Difference: 166400 (1300%)

Texel Rate

The Radeon R7 370 2G is quite a bit (more or less 609%) more effective at texture filtering than the Radeon HD 5550. (explain)

Radeon R7 370 2G		62400 Mtexels/sec
Radeon HD 5550		8800 Mtexels/sec
	Difference: 53600 (609%)

Pixel Rate

The Radeon R7 370 2G should be a lot (more or less 609%) more effective at FSAA than the Radeon HD 5550, and will be able to handle higher screen resolutions more effectively. (explain)

Radeon R7 370 2G		31200 Mpixels/sec
Radeon HD 5550		4400 Mpixels/sec
	Difference: 26800 (609%)

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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses 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 number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
