Radeon 540X is a graphics card from AMD, It has 512 stream processors, 14 nm's process technology makes us admire the strength of AMD, The number of transistors on the GPU is up to 2.2 billion, The GPU running frequency is 1124 MHz. Although the frequency will affect the performance of the graphics card, now, this parameter is not an important parameter, The graphics processor used by the GPU is Lexa, The whole graphics card layout uses GCN 4.0 architecture, Although Radeon 540X video memory is only 4 GB GDDR5, now measuring the performance of a graphics card does not only focus on the memory size, Its 1219 MHz Boost frequency is supposed to balance the heat and performance, 1.2 TFLOPS single-precision floating-point power can process more geometry in a short amount of time, The memory bit width is 64 bit (the number of bits of data that can be transferred in one clock cycle), The memory frequency (1.5 Gbps) parameter is not very important, just for a reference, The number of transistors on the GPU is up to 2.2 billion, The rated power 50 W is generally maintained at around 60% for daily use, Fans who like to watch HD video have a good fortune, as 32 texture processors on the graphics card can process HD video smoothly, Although the chip area is only 103 mm², it can also be inserted into a large number of transistors with the current AMD process technology.
The Radeon 540 uses the Polaris 12 core and has 8 CU units, which are 512 stream processors, as well as 32 textures and 16 raster units. RX 550 basic frequency is 1100MHz, acceleration frequency is 1183MHz, memory is 2 or 4GB GDDR5, equivalent memory frequency is 7000MHz, memory bandwidth is 128bit, and memory bandwidth is 112GB/s.

The name of the driver type in the system is: , and the drive type GUID is: .
1. The drivers you found aren't compatible.
2. You don't know how to search for drivers.
3. Your device isn't installed with drivers and appears as an "unknown device" in the system. You don't know how to find drivers for it.
This website offers a new method for finding drivers, a precise and fast way. Click here to use the new feature.Many hardware names are usually named after the chip model, and each chip model has its own dedicated driver, so as long as you know the chip model used by the hardware, you can find the right driver. For example, if your graphics card is named: "AMD Radeon RX 580", while actually the core chip model used is: "Radeon RX 580", then enter "Radeon RX 580" or "RX 580" to find the driver.
If you have a laptop or an all-in-one PC, you can also use the product name to search, and then go to the download page which has all the drivers for this machine (including: graphics card, network card, sound card, etc.). For example, if your laptop product name is: "Dell A6-9220e Inspiron Flagship", then type "Dell A6-9220e" to find all the drivers for this laptop.
Search steps:1. Enter a keyword in the input box and click the "Search" button
2. In the query results, find the driver file you need, and click the download button
• Can't find the required driver files?
• Don't know how to find driver files?
• Unable to download driver files due to unstable network?
You can try using this driver file finder. The method of use is very simple. The program will automatically list all the driver files available for your current system. You can install drivers for devices that do not have drivers installed, and you can also upgrade drivers to the latest driver version for devices that have already installed drivers. Click here to download the driver finder.
