The AMD Radeon HD 6620G is an integrated graphics unit found in certain AMD A-Series processors (A4-3300M, A6-3400M, A6-3420M, etc.). Here is some technical information about this graphics unit:

1. GPU Architecture:
The AMD Radeon HD 6620G is based on AMD's older Terascale 2 architecture.

2. Shader Units:
The Radeon HD 6620G has 320 shader units, also known as stream processors. These units perform calculations for graphics and parallel processing tasks.

3. Memory:
The graphics unit shares memory with the computer's system memory. It does not have dedicated video memory, but rather accesses the system's RAM.

4. Memory connection:
The memory connection is done via the system RAM and therefore depends on the configuration of the system.

5. API Support:
The Radeon HD 6620G supports older graphics APIs such as DirectX 11, OpenGL 4.1 and OpenCL 1.1.

6. Core Clock:
The exact core clock of the Radeon HD 6620G depends on the processor model and thermal conditions. However, it is usually between 400 MHz and 600 MHz.

7. Performance:
The performance of the Radeon HD 6620G is designed for use in light to moderate gaming and multimedia applications. However, it may not be suitable for more demanding games or applications.

8. Power Consumption:
Since it is an integrated graphics unit, the power consumption of the Radeon HD 6620G is relatively low compared to dedicated graphics cards.

9. Cooling:
Cooling of the Radeon HD 6620G is typically provided by the laptop's heatsink or other passive or active cooling solutions to ensure adequate heat dissipation.

The Radeon HD 6620G is designed to provide basic to mid-level graphics performance in laptops and desktop computers aimed at the everyday needs of multimedia applications and games.



AMD Radeon HD 6620G, known issues and bugs.


The AMD Radeon HD 6620G is an older integrated graphics unit found in certain AMD A-Series processors. Although it has been widely used in the past, there are some known issues and difficulties that some users may have experienced:

1. Driver incompatibilities:
As with many graphics solutions, driver incompatibilities can lead to a variety of issues including crashes, performance issues, or display errors. In particular, older driver versions may not be fully compatible with current operating systems or applications.

2. Performance Bottlenecks:
The Radeon HD 6620G is designed for light to moderate gaming and multimedia applications. Users may encounter performance bottlenecks, especially when running more demanding games or applications.
