Radeon HD 4350 vs Radeon R9 M270X

Intro

Compare all of that to the Radeon R9 M270X, which features a core clock speed of 725 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M270X should be a lot faster than the Radeon HD 4350 overall. (explain)

Radeon R9 M270X		72000 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 64000 (800%)

Texel Rate

The Radeon R9 M270X should be much (approximately 530%) faster with regards to AF than the Radeon HD 4350. (explain)

Radeon R9 M270X		29000 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 24400 (530%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M270X is the winner, by far. (explain)

Radeon R9 M270X		11600 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 9300 (404%)

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 (measured in megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

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