Radeon HD 4830 1GB vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which uses a 28 nm design. AMD has set the core speed at 925 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this particular card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M365X should in theory be quite a bit better than the Radeon HD 4830 1GB overall. (explain)

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

Texel Rate

The Radeon R9 M365X will be quite a bit (more or less 101%) faster with regards to texture filtering 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 using high levels of AA is important to you, then the Radeon R9 M365X is superior to the Radeon HD 4830 1GB, by far. (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 largest amount of data (in units of MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 texture map elements (texels) that are applied in one 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 this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
