GeForce GTX 465 vs Radeon R9 M385X

Intro

The GeForce GTX 465 comes with a GPU core speed of 607 MHz, and the 1024 MB of GDDR5 RAM runs at 802 MHz through a 256-bit bus. It also is comprised of 352 Stream Processors, 44 TAUs, and 32 Raster Operation Units.

Compare those specifications to the Radeon R9 M385X, which has clock speeds of 1100 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 465 should perform a bit faster than the Radeon R9 M385X in general. (explain)

GeForce GTX 465 102592 MB/sec
Radeon R9 M385X 96000 MB/sec
Difference: 6592 (7%)

Texel Rate

The Radeon R9 M385X will be a lot (about 131%) more effective at texture filtering than the GeForce GTX 465. (explain)

Radeon R9 M385X 61600 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 34892 (131%)

Pixel Rate

The GeForce GTX 465 is just a bit (approximately 10%) better at FSAA than the Radeon R9 M385X, and also should be able to handle higher resolutions more effectively. (explain)

GeForce GTX 465 19424 Mpixels/sec
Radeon R9 M385X 17600 Mpixels/sec
Difference: 1824 (10%)

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 max amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
