GeForce 8800 Ultra vs Radeon R9 M380

Intro

The GeForce 8800 Ultra uses a 90 nm design. nVidia has clocked the core speed at 612 MHz. The GDDR3 RAM runs at a frequency of 1080 MHz on this card. It features 128 SPUs along with 64 TAUs and 24 ROPs.

Compare all of that to the Radeon R9 M380, which comes with GPU clock speed of 1000 MHz, and 4096 MB of GDDR5 memory set to run at 1500 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 8800 Ultra should be 8% faster than the Radeon R9 M380 in general, due to its higher bandwidth. (explain)

GeForce 8800 Ultra 103680 MB/sec
Radeon R9 M380 96000 MB/sec
Difference: 7680 (8%)

Texel Rate

The Radeon R9 M380 will be a bit (about 2%) better at AF than the GeForce 8800 Ultra. (explain)

Radeon R9 M380 40000 Mtexels/sec
GeForce 8800 Ultra 39168 Mtexels/sec
Difference: 832 (2%)

Pixel Rate

The Radeon R9 M380 will be a small bit (about 9%) more effective at full screen anti-aliasing than the GeForce 8800 Ultra, and should be capable of handling higher screen resolutions more effectively. (explain)

Radeon R9 M380 16000 Mpixels/sec
GeForce 8800 Ultra 14688 Mpixels/sec
Difference: 1312 (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 information (counted in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's 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 rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
