Radeon HD 4830 1GB vs Radeon R9 M370X

Intro

The Radeon HD 4830 1GB features a core clock frequency of 575 MHz and a GDDR4 memory frequency of 900 MHz. It also makes use of a 256-bit memory bus, and uses a 55 nm design. It is comprised of 640(128x5) SPUs, 32 TAUs, and 16 ROPs.

Compare those specifications to the Radeon R9 M370X, which features GPU core speed of 800 MHz, and 2048 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

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

Texel Rate

The Radeon R9 M370X is a lot (more or less 74%) better 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 should be a lot (approximately 39%) more effective at full screen anti-aliasing than the Radeon HD 4830 1GB, and also able to handle higher screen resolutions without slowing down too much. (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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
