GeForce GTX 465 vs Radeon R9 M380

Intro

The GeForce GTX 465 makes use of a 40 nm design. nVidia has clocked the core speed at 607 MHz. The GDDR5 RAM runs at a speed of 802 MHz on this card. It features 352 SPUs as well as 44 TAUs and 32 ROPs.

Compare those specifications to the Radeon R9 M380, which features a clock frequency of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 465 should in theory perform a little bit faster than the Radeon R9 M380 overall. (explain)

GeForce GTX 465 102592 MB/sec
Radeon R9 M380 96000 MB/sec
Difference: 6592 (7%)

Texel Rate

The Radeon R9 M380 is quite a bit (about 50%) better at anisotropic filtering than the GeForce GTX 465. (explain)

Radeon R9 M380 40000 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 13292 (50%)

Pixel Rate

The GeForce GTX 465 will be much (more or less 21%) more effective at FSAA than the Radeon R9 M380, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 465 19424 Mpixels/sec
Radeon R9 M380 16000 Mpixels/sec
Difference: 3424 (21%)

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 largest amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per 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 - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
