Radeon HD 4830 1GB vs Radeon R9 M370X

Intro

The Radeon HD 4830 1GB makes use of a 55 nm design. AMD has set the core speed at 575 MHz. The GDDR4 memory runs at a speed of 900 MHz on this model. It features 640(128x5) SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Compare those specifications to the Radeon R9 M370X, which features a clock speed of 800 MHz and a GDDR5 memory frequency of 1125 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M370X will be 25% faster than the Radeon HD 4830 1GB overall, because of its greater bandwidth. (explain)

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

Texel Rate

The Radeon R9 M370X is quite a bit (more or less 74%) faster with regards to anisotropic 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 (about 39%) better at AA than the Radeon HD 4830 1GB, and will be able to handle higher screen resolutions while still performing well. (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 largest amount of data (in units of MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's 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 amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics 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 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 figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
