AMD Radeon RX 550
About GPU
The AMD Radeon RX 550 is a budget-friendly graphics processing unit (GPU) that offers decent performance for casual gaming and light multimedia tasks. With a base clock speed of 1100MHz and a boost clock speed of 1183MHz, this GPU is capable of handling most modern games at lower settings and resolutions.
Equipped with 2GB of GDDR5 memory with a memory clock of 1750MHz, the Radeon RX 550 provides enough memory bandwidth to handle its 512 shading units and 512KB of L2 cache. With a thermal design power (TDP) of only 50W, this GPU is also relatively power-efficient, making it a suitable choice for systems with limited power capabilities.
In terms of performance, the Radeon RX 550 delivers a theoretical performance of 1.211 TFLOPS, making it suitable for entry-level gaming and multimedia tasks. In 3DMark Time Spy, it scores 1195, indicating its capability to handle DirectX 12 titles. In game benchmarks, it achieves 84fps in GTA 5 at 1080p, 20fps in Battlefield 5 at 1080p, and 21fps in Shadow of the Tomb Raider at 1080p.
Overall, the AMD Radeon RX 550 is a solid option for budget-conscious gamers or users looking to upgrade from integrated graphics. Its low power consumption, respectable gaming performance at lower settings, and affordable price point make it a compelling choice for those on a tight budget. However, for users looking to play more demanding titles at higher settings, a higher-end GPU would be necessary.

TMUs
?
Texture Mapping Units (TMUs) serve as components of the GPU, which are capable of rotating, scaling, and distorting binary images, and then placing them as textures onto any plane of a given 3D model. This process is called texture mapping.

Memory Bus
?
The memory bus width refers to the number of bits of data that the video memory can transfer within a single clock cycle. The larger the bus width, the greater the amount of data that can be transmitted instantaneously, making it one of the crucial parameters of video memory. The memory bandwidth is calculated as: Memory Bandwidth = Memory Frequency x Memory Bus Width / 8. Therefore, when the memory frequencies are similar, the memory bus width will determine the size of the memory bandwidth.

Bandwidth
?
Memory bandwidth refers to the data transfer rate between the graphics chip and the video memory. It is measured in bytes per second, and the formula to calculate it is: memory bandwidth = working frequency × memory bus width / 8 bits.

Pixel Rate
?
Pixel fill rate refers to the number of pixels a graphics processing unit (GPU) can render per second, measured in MPixels/s (million pixels per second) or GPixels/s (billion pixels per second). It is the most commonly used metric to evaluate the pixel processing performance of a graphics card.
18.93 GPixel/s
Texture Rate
?
Texture fill rate refers to the number of texture map elements (texels) that a GPU can map to pixels in a single second.

FP16 (half)
?
An important metric for measuring GPU performance is floating-point computing capability. Half-precision floating-point numbers (16-bit) are used for applications like machine learning, where lower precision is acceptable. Single-precision floating-point numbers (32-bit) are used for common multimedia and graphics processing tasks, while double-precision floating-point numbers (64-bit) are required for scientific computing that demands a wide numeric range and high accuracy.

ROPs
?
The Raster Operations Pipeline (ROPs) is primarily responsible for handling lighting and reflection calculations in games, as well as managing effects like anti-aliasing (AA), high resolution, smoke, and fire. The more demanding the anti-aliasing and lighting effects in a game, the higher the performance requirements for the ROPs; otherwise, it may result in a sharp drop in frame rate.
