Radeon HD 4830 1GB vs Radeon R7 M360

Intro

Compare that to the Radeon R7 M360, which comes with clock speeds of 1125 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 4830 1GB should be 260% faster than the Radeon R7 M360 in general, due to its greater data rate. (explain)

Radeon HD 4830 1GB		57600 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 41600 (260%)

Texel Rate

The Radeon R7 M360 should be much (more or less 47%) faster with regards to AF than the Radeon HD 4830 1GB. (explain)

Radeon R7 M360		27000 Mtexels/sec
Radeon HD 4830 1GB		18400 Mtexels/sec
	Difference: 8600 (47%)

Pixel Rate

The Radeon HD 4830 1GB is a little bit (about 2%) faster with regards to AA than the Radeon R7 M360, and also should be capable of handling higher resolutions without slowing down too much. (explain)

Radeon HD 4830 1GB		9200 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 200 (2%)

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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
