How to overclock a video card using MSI Afterburner

How to overclock an AMD graphics card

Many graphics accelerators from AMD are initially overclocked better than Nvidia, so they do not have such significant overclocking potential. Especially extreme models with factory overclocking. In terms of frequency, Radeon memory “chases” perfectly, the peak value is often limited by the physical capabilities of the chips themselves.

Overclocking RX 6000 series

New generation architecture based on the Navi 2 video chip divided into clusters. Each consists of 64 compute units and 4 texture units. 7nm process technology with increased energy efficiency (up to 50%) raised frequencies and overclocking capabilities. Boost frequencies exceed 2 GHz. Ray tracing calculation blocks improve the realism of scene lighting.

An additional third-level cache will reduce the frequency of external memory accesses. The bandwidth of Infinity Cache on a 256-bit bus will reduce electricity consumption, heat, and will delight fans of overclocking. Variable Rate Shading will change the rendering quality of scene segments (relevant for racing).

Overclocking RX 5000 Series

The RDNA architecture is the result of 8 years of work by the computer giant, aimed at working with three-dimensional applications. This is not an ordinary architecture, but a synthesis of a number of technological solutions of the company for playing three-dimensional content – games. Three frequencies are indicated: nominal, game, Boost. They work through the new high-speed PCI Express 4.0 interface. Optimization managed to reduce the thermal pack by ~23% and increase the performance up to 14%. Cost-effectiveness is achieved due to the almost halved area of ​​the crystal – to get a noticeable increase in performance during overclocking, you will have to change the cooling.

Overclocking RX Vega Series

In addition to processing real and integer numbers, Vega performs integer operations with different accuracy (relevant for machine learning, mining). The NCU chip enhances throughput by combining single-bit operations. Redesigned tile rendering technology reduces the number of external memory accesses. It is activated at the driver level, noticeably accelerates gaming performance and reduces bus load by up to 33%.
