Radeon HD 4830 1GB vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which features a clock speed of 925 MHz and a GDDR5 memory frequency of 1125 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M365X should in theory be quite a bit superior to the Radeon HD 4830 1GB in general. (explain)

Radeon R9 M365X		72000 MB/sec
Radeon HD 4830 1GB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M365X is much (approximately 101%) faster with regards to AF than the Radeon HD 4830 1GB. (explain)

Radeon R9 M365X		37000 Mtexels/sec
Radeon HD 4830 1GB		18400 Mtexels/sec
	Difference: 18600 (101%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M365X is a better choice, and very much so. (explain)

Radeon R9 M365X		14800 Mpixels/sec
Radeon HD 4830 1GB		9200 Mpixels/sec
	Difference: 5600 (61%)

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 max amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should 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 texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core clock 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 maximum number of pixels that the graphics chip could 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 the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 ability to get to the max fill rate.
