About AMD Radeon RX 580X Mobile

The AMD Radeon RX 580X Mobile is an end-of-life mobile graphics module built on the Polaris 20 chip using the GCN 4.0 architecture. Fabricated on GlobalFoundries' 14 nm process, it packs 5,700 million transistors into a 232 mm² die, yielding a density of 24.6M / mm². The database places this GPU at the 50th percentile among all GPUs, indicating a median performance tier, while its average benchmark score is recorded as 0, meaning no aggregated samples are available for direct comparison. The card was released on April 10, 2018, and sits within the Polaris Mobile (RX M500X) generation, bridging the "Gem System" predecessor and "Navi Mobile" successor.

Benchmark Performance

The lack of an average benchmark score (0) forces reliance on theoretical specifications. The FP32 compute throughput is 5.834 TFLOPS, with a texture fill rate of 182.3 GTexel/s and a pixel rate of 40.51 GPixel/s. These figures align with a mid-range mobile part. The 50th percentile standing confirms it sits exactly in the middle of the database's performance distribution, neither a low-end entry nor a high-end performer. The FP16 rate is identical at 5.834 TFLOPS (1:1), meaning no dedicated half-precision acceleration is present; this is typical for GCN 4.0. For rasterization workloads, the 32 ROPs and 144 TMUs provide a balanced output, but the 40.51 GPixel/s pixel rate suggests a ceiling for high-resolution fill-rate demands. The 2304 shading units handle compute tasks competently for a mobile part of this era. The texture rate of 182.3 GTexel/s indicates strong texel throughput, beneficial for detailed surfaces. The pixel rate of 40.51 GPixel/s, derived from 32 ROPs, suggests a limit on fill-rate-heavy effects like high-resolution shadows. Without rival data, the percentile is the sole comparative anchor, positioning this card as a solid mainstream option for 1080p gaming rather than a high-refresh or 4K solution. The 5.834 TFLOPS figure is a robust baseline for modern game engines, but it does not approach the compute levels needed for high-end VR or 4K rendering.

Power and Cooling

The thermal design power is fixed at 100 W, which is moderate for a mobile GPU. The card uses an MXM Module slot width and interfaces via MXM-B (3.0). Notably, the power connectors field is listed as "None," indicating the module draws all required power through the MXM connector itself, eliminating the need for auxiliary PCIe power cables. The suggested PSU field is absent, so no power supply recommendation is provided in the data. Cooling responsibility falls entirely on the host portable device, as the display outputs are listed as "Portable Device Dependent." This means the chassis must provide adequate airflow and heat dissipation for the 100 W envelope. The 14 nm process helps manage thermal output, but the 5,700 million transistors on a 232 mm² die still generate significant heat under load. The lack of a dedicated power connector simplifies installation in compatible MXM-B systems, but it also ties the card's power delivery to the motherboard's design. The MXM-B (3.0) bus interface is a standard for mobile modules, and the "None" power connector requirement simplifies integration into compatible systems. The 100 W TDP is a key constraint for thin-and-light laptops, which may struggle to cool this module under sustained load.

Who Should Consider It

Benchmark results indicate a GPU positioned at the 50th percentile, making it suitable for mainstream 1080p gaming. The 8 GB GDDR5 memory and 256.0 GB/s bandwidth provide enough headroom for high-resolution textures at 1080p and moderate settings at 1440p. The 5.834 TFLOPS FP32 throughput handles modern game engines at medium-to-high presets in 1080p. For 1080p, the 5.834 TFLOPS throughput can drive high settings in most titles, while esports titles may run at maximum settings. At 1440p, medium settings are more realistic. However, the 40.51 GPixel/s pixel rate and 32 ROPs will struggle with 4K rendering, so users targeting 4K should look elsewhere. The MXM-B (3.0) interface means this is exclusively for laptops or portable devices with an MXM slot; it is not a desktop card. Given its end-of-life production status, it is best suited for users upgrading an existing MXM-B notebook or those purchasing a refurbished system. For 1080p esports titles and older AAA games, this card offers a viable experience. The 100 W TDP also makes it a reasonable choice for thicker gaming laptops that can accommodate higher-power modules. Users with a 1440p display should expect to lower graphical presets to maintain playable frame rates.

Ray Tracing and Feature Set

The RX 580X Mobile has no RT cores or tensor cores, as indicated by null values in the data. This means ray tracing and AI-accelerated features are not available in hardware. The API support includes DirectX 12 (12_0), which is the baseline feature level, but without dedicated RT hardware, any ray tracing effects would rely on software fallbacks, which is impractical. OpenGL 4.6 and Vulkan 1.3 are supported, allowing for modern cross-platform rendering. The FP16 performance matches FP32 at 5.834 TFLOPS (1:1), which is a notable characteristic of the GCN 4.0 architecture, but it does not provide the half-rate boost seen in some competing designs. The feature set is therefore focused on traditional rasterization. The 14 nm process and 5,700 million transistor count suggest a mature design optimized for power efficiency rather than cutting-edge features. Without tensor cores, features like DLSS are unavailable. For users requiring ray tracing, this card is not suitable. The DirectX 12 (12_0) support ensures compatibility with modern titles, but the lack of hardware acceleration for advanced effects limits future-proofing.

Memory Subsystem

The memory subsystem consists of 8 GB of GDDR5 running at 2000 MHz, with an effective data rate of 8 Gbps. The bus width is 256 bits, yielding a total bandwidth of 256.0 GB/s. This bandwidth is adequate for 1080p gaming and can support high-resolution textures without severe bottlenecks. At 1440p, the 256.0 GB/s may become a limiting factor in texture-heavy scenes, but it remains workable. For 4K, the combination of 8 GB capacity and 256.0 GB/s bandwidth is insufficient for high-detail settings, as the pixel rate of 40.51 GPixel/s also caps fill-rate performance. The memory clock of 2000 MHz is standard for GDDR5 of this generation. The 256-bit bus is a positive attribute, providing a balanced memory interface that matches the 5.834 TFLOPS compute throughput. The 8 GB capacity is generous for a 2018 mobile part, allowing for large texture packs in modern games. Overall, the memory subsystem is well-matched to the card's intended 1080p segment, but the 256.0 GB/s bandwidth is a hard ceiling for high-resolution workloads.

How It Compares

The data pack does not list any nearest rivals, so direct percentage deltas cannot be provided. The primary comparative metric is the 50th percentile standing, which places this GPU exactly at the median of all GPUs in the database. This indicates a performance level that is neither top-tier nor bottom-tier. In the product stack, its predecessor is listed as "Gem System" and its successor as "Navi Mobile," suggesting it bridges two mobile generations. The RX 580X Mobile's theoretical specifications—5.834 TFLOPS FP32, 182.3 GTexel/s texture rate, and 256.0 GB/s bandwidth—position it as a competent mid-range mobile solution. Compared to the average GPU, it sits in the middle, meaning it will outperform low-end integrated graphics but lag behind high-end discrete parts. The absence of rival data means users must rely on the percentile and the card's own specs to gauge its standing. The 50th percentile is a clear signal that this is a balanced, mainstream offering. The end-of-life status means it is no longer manufactured, but its 50th percentile performance keeps it relevant for legacy systems. The 100 W TDP and MXM form factor further differentiate it from desktop cards, making it a niche product for portable gaming.
