Radeon HD 4650 512MB vs Radeon R7 M360

Intro

Compare those specifications to the Radeon R7 M360, which has a clock frequency of 1125 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 64-bit memory bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should have the same performance. (explain)

Texel Rate

The Radeon R7 M360 will be much (approximately 41%) better at AF than the Radeon HD 4650 512MB. (explain)

Radeon R7 M360		27000 Mtexels/sec
Radeon HD 4650 512MB		19200 Mtexels/sec
	Difference: 7800 (41%)

Pixel Rate

The Radeon R7 M360 should be a lot (about 88%) more effective at anti-aliasing than the Radeon HD 4650 512MB, and will be able to handle higher resolutions more effectively. (explain)

Radeon R7 M360		9000 Mpixels/sec
Radeon HD 4650 512MB		4800 Mpixels/sec
	Difference: 4200 (88%)

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 data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 per second. This 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 potential to get to the max fill rate.
