Radeon HD 4850 2GB vs Radeon R9 M265X

Intro

The Radeon HD 4850 2GB makes use of a 55 nm design. AMD has set the core frequency at 625 MHz. The GDDR4 memory is set to run at a speed of 993 MHz on this card. It features 800(160x5) SPUs along with 40 TAUs and 16 ROPs.

Compare all of that to the Radeon R9 M265X, which comes with GPU clock speed of 575 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Radeon R9 M265X 23000 Mtexels/sec
Difference: 2000 (9%)

Pixel Rate

The Radeon HD 4850 2GB will be a little bit (about 9%) more effective at AA than the Radeon R9 M265X, and also will be capable of handling higher resolutions better. (explain)

Radeon HD 4850 2GB 10000 Mpixels/sec
Radeon R9 M265X 9200 Mpixels/sec
Difference: 800 (9%)

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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred past the external memory interface in one second. It is worked out 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 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
