GeForce 8600 GT 1GB DDR2 vs Radeon RX 5700

Intro

The GeForce 8600 GT 1GB DDR2 uses a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The DDR2 memory is set to run at a speed of 400 MHz on this specific model. It features 32 SPUs along with 16 TAUs and 8 ROPs.

Compare those specs to the Radeon RX 5700, which has a core clock speed of 1465 MHz and a GDDR6 memory frequency of 1750 MHz. It also features a 256-bit memory bus, and makes use of a 7 nm design. It is made up of 2304 SPUs, 144 TAUs, and 64 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
