Radeon R5 M330 vs Radeon R9 270

Intro

Compare those specs to the Radeon R9 270, which makes use of a 28 nm design. AMD has set the core frequency at 900 MHz. The GDDR5 RAM works at a frequency of 1400 MHz on this particular card. It features 1280 SPUs along with 80 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 270 is 1144% faster than the Radeon R5 M330 overall, due to its greater bandwidth. (explain)

Radeon R9 270		179200 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 164800 (1144%)

Texel Rate

The Radeon R9 270 should be a lot (more or less 250%) more effective at AF than the Radeon R5 M330. (explain)

Radeon R9 270		72000 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 51400 (250%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 270 is superior to the Radeon R5 M330, and very much so. (explain)

Radeon R9 270		28800 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 20560 (250%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at 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 the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
