Radeon HD 4850 X2 1GB vs Radeon R9 M375X

Intro

The Radeon HD 4850 X2 1GB features a GPU core clock speed of 625 MHz, and the 1024 MB of GDDR3 RAM runs at 993 MHz through a 256-bit bus. It also is made up of 800(160x5) SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Compare all that to the Radeon R9 M375X, which has a clock frequency of 1015 MHz and a GDDR5 memory speed 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 Texture Address Units, and 16 Raster Operation Units.

Radeon R9 M375X 72000 MB/sec
Difference: 55104 (77%)

Texel Rate

The Radeon HD 4850 X2 1GB is quite a bit (approximately 23%) better at anisotropic filtering than the Radeon R9 M375X. (explain)

Radeon HD 4850 X2 1GB 50000 Mtexels/sec
Radeon R9 M375X 40600 Mtexels/sec
Difference: 9400 (23%)

Pixel Rate

The Radeon HD 4850 X2 1GB will be a lot (approximately 23%) more effective at anti-aliasing than the Radeon R9 M375X, and should be capable of handling higher resolutions better. (explain)

Radeon HD 4850 X2 1GB 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 information (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 can be applied per second. This figure is worked out by multiplying the total texture units by the core 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
