Radeon HD 4850 X2 512MB vs Radeon R9 M375X

Intro

The Radeon HD 4850 X2 512MB comes with core speeds of 625 MHz on the GPU, and 993 MHz on the 512 MB of GDDR3 memory. It features 800(160x5) SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Compare those specs to the Radeon R9 M375X, which features GPU core speed of 1015 MHz, and 4096 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 4850 X2 512MB should theoretically be quite a bit superior to the Radeon R9 M375X overall. (explain)

Radeon HD 4850 X2 512MB 127104 MB/sec
Radeon R9 M375X 72000 MB/sec
Difference: 55104 (77%)

Texel Rate

The Radeon HD 4850 X2 512MB is a lot (approximately 23%) faster with regards to AF than the Radeon R9 M375X. (explain)

Radeon HD 4850 X2 512MB 50000 Mtexels/sec
Radeon R9 M375X 40600 Mtexels/sec
Difference: 9400 (23%)

Pixel Rate

If using a high resolution is important to you, then the Radeon HD 4850 X2 512MB is a better choice, and very much so. (explain)

Radeon HD 4850 X2 512MB 20000 Mpixels/sec
Radeon R9 M375X 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 data (in units of MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 amount of texture map elements (texels) that are applied per second. This figure 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
