Radeon HD 5870 vs Radeon R5 M330

Intro

The Radeon HD 5870 features a GPU core speed of 850 MHz, and the 1024 MB of GDDR5 RAM runs at 1200 MHz through a 256-bit bus. It also features 1600(320x5) SPUs, 80 Texture Address Units, and 32 ROPs.

Compare those specifications to the Radeon R5 M330, which has GPU core speed of 1030 MHz, and 2048 MB of DDR3 memory running at 900 MHz through a 64-bit bus. It also is comprised of 320 Stream Processors, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 5870 should be 967% quicker than the Radeon R5 M330 in general, due to its higher data rate. (explain)

Radeon HD 5870 153600 MB/sec
Radeon R5 M330 14400 MB/sec
Difference: 139200 (967%)

Texel Rate

The Radeon HD 5870 should be quite a bit (about 230%) more effective at AF than the Radeon R5 M330. (explain)

Radeon HD 5870 68000 Mtexels/sec
Radeon R5 M330 20600 Mtexels/sec
Difference: 47400 (230%)

Pixel Rate

If using a high resolution is important to you, then the Radeon HD 5870 is the winner, by a large margin. (explain)

Radeon HD 5870 27200 Mpixels/sec
Radeon R5 M330 8240 Mpixels/sec
Difference: 18960 (230%)

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 (in units of MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 are processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the 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 could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
