GeForce GTX 465 vs Radeon R9 M385X

Intro

The GeForce GTX 465 makes use of a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 memory works at a frequency of 802 MHz on this particular model. It features 352 SPUs along with 44 TAUs and 32 Rasterization Operator Units.

Compare all of that to the Radeon R9 M385X, which has GPU core speed of 1100 MHz, and 4096 MB of GDDR5 RAM running at 1500 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 TAUs, and 16 ROPs.

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

Texel Rate

The Radeon R9 M385X should be much (approximately 131%) faster with regards to AF 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 should be a bit (about 10%) better at AA than the Radeon R9 M385X, and also will be able to handle higher screen 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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
