Radeon HD 4650 512MB vs Radeon R7 M360

Intro

Compare all of that to the Radeon R7 M360, which makes use of a 28 nm design. AMD has clocked the core speed at 1125 MHz. The DDR3 memory runs at a speed of 1000 MHz on this card. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The Radeon R7 M360 will be a lot (approximately 41%) faster with regards to anisotropic filtering 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

If using high levels of AA is important to you, then the Radeon R7 M360 is a better choice, by far. (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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, the result should 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 amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core 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 in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one 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 drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
