Radeon HD 4830 1GB vs Radeon R9 M370X

Intro

Compare all of that to the Radeon R9 M370X, which features core speeds of 800 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M370X should in theory be quite a bit better than the Radeon HD 4830 1GB overall. (explain)

Radeon R9 M370X		72000 MB/sec
Radeon HD 4830 1GB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M370X should be a lot (approximately 74%) more effective at texture filtering than the Radeon HD 4830 1GB. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 4830 1GB		18400 Mtexels/sec
	Difference: 13600 (74%)

Pixel Rate

The Radeon R9 M370X is much (more or less 39%) faster with regards to FSAA than the Radeon HD 4830 1GB, and also able to handle higher screen resolutions better. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon HD 4830 1GB		9200 Mpixels/sec
	Difference: 3600 (39%)

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 (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
