GeForce 8800 GS vs Radeon R7 M265

Intro

The GeForce 8800 GS makes use of a 65 nm design. nVidia has set the core frequency at 550 MHz. The GDDR3 RAM runs at a frequency of 800 MHz on this specific card. It features 96 SPUs along with 48 TAUs and 12 Rasterization Operator Units.

Compare all of that to the Radeon R7 M265, which features a core clock speed of 725 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 8800 GS should be 20% faster than the Radeon R7 M265 overall, because of its higher bandwidth. (explain)

GeForce 8800 GS 38400 MB/sec
Radeon R7 M265 32000 MB/sec
Difference: 6400 (20%)

Texel Rate

The GeForce 8800 GS will be a lot (about 52%) more effective at anisotropic filtering than the Radeon R7 M265. (explain)

GeForce 8800 GS 26400 Mtexels/sec
Radeon R7 M265 17400 Mtexels/sec
Difference: 9000 (52%)

Pixel Rate

The GeForce 8800 GS will be a bit (about 14%) more effective at full screen anti-aliasing than the Radeon R7 M265, and also able to handle higher screen resolutions more effectively. (explain)

GeForce 8800 GS 6600 Mpixels/sec
Radeon R7 M265 5800 Mpixels/sec
Difference: 800 (14%)

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 largest amount of data (in units of MB per second) that can be transported past the external memory interface in a second. It's 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 DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs 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 rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
