AMD Radeon R7 M340
The Radeon R7 M340 is a GPU from AMD released in 2015. This chip has a bad gaming score at 4% in our GPU benchmark.
The Radeon R7 M340 has 4 GiB of DDR3 memory, with a total memory bandwidth of 15 GB/s. The memory bus has a width of 128 bits. More memory is beneficial when gaming at high resolutions as the memory needs to store the frame buffer and all the game textures. If you run out of memory, you will experience poor performance as the GPU needs to swap data in and out of the memory as it is used.
In terms of clock speed, the Radeon R7 M340 GPU core runs at a frequency of 620 MHz and if power and temperature permits, it can boost up to 1021 MHz. The core clock is directly related to the performance of a GPU, the higher the clock, the more processing can be done per second. A higher clock does not guarantee better performance by itself, this also depends on the number of shading units and other elements of the pipeline.
The performance specs of the Radeon R7 M340 are this AMD GPU has a pixel rate of 6 Gigapixels/s, the number of pixels the GPU is capable of outputting every second. Furthermore, it has a texture fill rate of 17 Gigatexels/s, the number of pixels the GPU can renderer per second.
As for rendering API support, the Radeon R7 M340 supports up to DirectX 12. In addition, in cross-platform titles, OpenGL 4.6 features are supported. Newer APIs are usually more efficient, allowing for better performance in games and better graphical effects.
The raw technical specs of the Radeon R7 M340 are: 384 total shading units (general purpose parallel cores capable of processing different aspects of the graphics pipeline), 24 texture mapping units (specialised processors for texture operations, this determines the texture rate) and 8 render output processors or units (the final step in the rendering pipeline, responsible for rasterising the image)
