Radeon HD 4650 1GB vs Radeon R7 M360

Intro

Compare those specifications to the Radeon R7 M360, which makes use of a 28 nm design. AMD has clocked the core speed at 1125 MHz. The DDR3 RAM works at a speed of 1000 MHz on this particular card. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R7 M360 is superior to the Radeon HD 4650 1GB, by far. (explain)

Radeon R7 M360		9000 Mpixels/sec
Radeon HD 4650 1GB		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 data (in units of megabytes per second) that can be moved 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, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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