Radeon HD 4850 X2 512MB vs Radeon R9 M375

Intro

The Radeon HD 4850 X2 512MB comes with a GPU core speed of 625 MHz, and the 512 MB of GDDR3 RAM is set to run at 993 MHz through a 256-bit bus. It also is comprised of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Compare those specs to the Radeon R9 M375, which comes with core clock speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 memory. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 4850 X2 512MB is 261% quicker than the Radeon R9 M375 overall, because of its higher data rate. (explain)

Radeon HD 4850 X2 512MB 127104 MB/sec
Radeon R9 M375 35200 MB/sec
Difference: 91904 (261%)

Texel Rate

The Radeon HD 4850 X2 512MB is much (approximately 23%) faster with regards to texture filtering than the Radeon R9 M375. (explain)

Radeon HD 4850 X2 512MB 50000 Mtexels/sec
Radeon R9 M375 40600 Mtexels/sec
Difference: 9400 (23%)

Pixel Rate

The Radeon HD 4850 X2 512MB is quite a bit (about 23%) more effective at AA than the Radeon R9 M375, and should be capable of handling higher screen resolutions more effectively. (explain)

Radeon HD 4850 X2 512MB 20000 Mpixels/sec
Radeon R9 M375 16240 Mpixels/sec
Difference: 3760 (23%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of 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 output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
