Radeon HD 4870 1GB vs Radeon R7 M360

Intro

Compare that to the Radeon R7 M360, which makes use of a 28 nm design. AMD has set the core speed at 1125 MHz. The DDR3 RAM runs at a speed of 1000 MHz on this card. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon HD 4870 1GB should be a lot faster than the Radeon R7 M360 in general. (explain)

Radeon HD 4870 1GB		115200 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 99200 (620%)

Texel Rate

The Radeon HD 4870 1GB will be a small bit (about 11%) more effective at anisotropic filtering than the Radeon R7 M360. (explain)

Radeon HD 4870 1GB		30000 Mtexels/sec
Radeon R7 M360		27000 Mtexels/sec
	Difference: 3000 (11%)

Pixel Rate

The Radeon HD 4870 1GB will be much (about 33%) faster with regards to anti-aliasing than the Radeon R7 M360, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon HD 4870 1GB		12000 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 3000 (33%)

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 largest amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
