Radeon RX 550X GPU Core

Shader units and compute resources

The AMD Radeon RX 550X GPU core specifications define its raw processing power for graphics and compute workloads. Shading units (also called CUDA cores, stream processors, or execution units depending on manufacturer) handle the parallel calculations required for rendering. TMUs (Texture Mapping Units) process texture data, while ROPs (Render Output Units) handle final pixel output. Higher shader counts generally translate to better GPU benchmark performance, especially in demanding games and 3D applications.

About AMD Radeon RX 550X

The GeForce AMD Radeon RX 550X, launched in December 2018, targets budget‑conscious workstations and casual gamers. With a 4 GB GDDR5 memory pool and a 14 nm GCN 4.0 architecture, can it deliver consistent performance at 1080p? Its base clock of 1,100 MHz and boost up to 1,183 MHz suggest a modest but efficient processing envelope. The 50 W TDP, coupled with a PCIe 3.0 x8 interface, raises the question of whether additional power connectors are even required. Benchmark scores of 11,165 in Geekbench Vulkan and 9,025 in OpenCL hint at respectable compute capability for its class. Yet, how does this translate to real‑world frame rates in contemporary titles?

When evaluating the AMD Radeon RX 550X for modern games, one must consider its limited ray‑tracing support and the absence of dedicated DLSS hardware. However, AMD’s FidelityFX Super Resolution can still provide a modest uplift in visual fidelity without a heavy performance penalty. The 4 GB VRAM bandwidth, while adequate for medium‑detail textures, may become a bottleneck at higher resolutions or ultra settings. Power requirements remain low, making the GeForce AMD Radeon RX 550X an attractive option for compact builds and office PCs. Recommended titles such as “Fortnite,” “League of Legends,” and “Valorant” run comfortably at 1080p with medium to high presets. For more demanding AAA experiences, the RX 550X is best paired with reduced settings to maintain playable frame rates.

  1. 1080p 60 fps in popular eSports titles such as CS:GO and Rocket League.
  2. Up to 2560×1440 resolution at low to medium settings in less demanding games.
  3. Basic ray‑tracing support limited to low‑complexity scenes.
  4. FidelityFX Super Resolution (FSR) 1.0 enabled for modest performance gains.
  5. 4 GB GDDR5 memory delivering ~112 GB/s bandwidth.
  6. Maximum power draw of 50 W, eliminating the need for external PCIe power connectors.
