GeForce GTX 465 vs Radeon R9 M385X

Intro

The GeForce GTX 465 uses a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 memory works at a speed of 802 MHz on this particular card. It features 352 SPUs as well as 44 TAUs and 32 Rasterization Operator Units.

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

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 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 anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
