How It Compares

The FACT PACK does not include any nearest rivals, benchmark scores, or percentile comparisons for the AMD Radeon PRO W7400. Therefore, a direct quantitative comparison against competing workstation or consumer graphics cards is not possible based on the available data. The card holds a 50th percentile ranking among all GPUs, indicating it sits at the median point of performance across the entire spectrum of graphics hardware. Without specific rival data, the analysis must focus on the card's absolute specifications and its architectural positioning within the Radeon PRO lineup, noting its role as a successor to the Radeon Pro Vega series.

The absence of comparison data means that statements about its relative standing against specific models like an RTX A-series or a previous-generation Radeon PRO card cannot be made. The card's performance class can be inferred from its FP32 compute rating of 7.885 TFLOPS and its memory subsystem, but these are absolute figures. The 50th percentile ranking suggests that half of all GPUs in the database are faster and half are slower, but the exact composition of that field is unknown. This places the W7400 as a middle-ground performer, suitable for tasks that do not demand top-tier compute power but require professional driver support and features.

Given the lack of rival data, the "How It Compares" section must rely on the card's internal metrics. Its 55 W TDP is exceptionally low, suggesting it operates in a power envelope similar to entry-level consumer cards, yet its 8 GB VRAM and 172.8 GB/s bandwidth provide a more capable memory foundation than typical low-power parts. The 1792 shading units and 28 ray tracing cores indicate a modern architecture with hardware-accelerated ray tracing, setting it apart from older professional cards that lack this feature. However, without rivals, the narrative must pivot to describing what these specifications enable in absolute terms rather than relative performance deltas.

Ray Tracing and Feature Set

The AMD Radeon PRO W7400 includes dedicated hardware for ray tracing, featuring 28 RT cores. This architectural inclusion provides hardware-accelerated ray tracing capabilities for supported professional applications, such as 3D rendering and visualization workloads. The card's RDNA 3.0 architecture is designed to handle these tasks more efficiently than previous generations that relied on compute shaders for ray intersection calculations. The presence of these cores means that applications utilizing DXR or Vulkan ray tracing extensions can offload the traversal and intersection work to dedicated hardware.

In terms of API support, the W7400 is compliant with DirectX 12 Ultimate (feature level 12_2), which is the current standard for modern gaming and professional graphics features, including variable rate shading, mesh shaders, and ray tracing. It also supports OpenGL 4.6 and Vulkan 1.4, ensuring compatibility with a wide range of professional software that may rely on these older or cross-platform APIs. The card does not list tensor cores in the FACT PACK, indicating that it does not have dedicated AI acceleration hardware like NVIDIA's Tensor Cores, but the 1792 shading units can still perform FP16 compute at a 1:1 ratio with FP32, providing 7.885 TFLOPS for both data types.

The feature set also includes support for DisplayPort 2.1 outputs, with four such ports available. This is a significant connectivity feature, as it allows for high-resolution and high-refresh-rate displays, as well as multi-monitor setups, using the latest display interface standard. The card's PCIe 4.0 x8 interface is sufficient for its bandwidth needs, though it is a half-width connection compared to the x16 slots used by higher-end cards. This combination of RT cores, modern API support, and advanced display outputs positions the W7400 as a capable professional card for visualization tasks, though its compute throughput is modest at 7.885 TFLOPS FP32.

Who Should Consider It

The AMD Radeon PRO W7400 is suited for professionals who require certified drivers and workstation-specific features but do not need extreme compute performance.

The 172.8 GB/s bandwidth is adequate for handling textures and geometry at these resolutions, but it may become a bottleneck at 4K with high-detail scenes. Users working with CAD, 3D modeling, and light video editing will find the card's 7.885 TFLOPS FP32 performance sufficient for interactive viewport work and moderate rendering tasks.

The card's low power consumption and single-slot design make it an excellent choice for compact workstations or systems with limited internal space. The 55 W TDP means it does not require auxiliary power connectors, simplifying installation in pre-built systems or those with modest power supplies. Professionals who prioritize a quiet and cool operating environment will appreciate the lack of a high-power cooling solution. The 4x DisplayPort 2.1 outputs enable multi-monitor configurations, which is beneficial for financial trading, data analysis, or any workflow that relies on multiple displays.

However, for users who need to render complex scenes with heavy ray tracing or handle very large datasets that exceed 8 GB of VRAM, the W7400 will be limiting. Its 50th percentile ranking suggests it is not a top-tier performer, so professionals with demanding simulation or high-end 3D rendering workloads should look at higher-tier options. The card is also not ideal for AI or machine learning tasks due to the absence of tensor cores, though its FP16 performance at 1:1 ratio with FP32 can handle some basic compute tasks. Ultimately, it is a solid entry-level professional card for mainstream tasks, not a high-end compute accelerator.

Benchmark Performance

The FACT PACK provides no benchmark scores, average scores, or nearest rival data for the AMD Radeon PRO W7400. The only performance-related metric is the percentileVsAllGpus field, which indicates a value of 50. This means the card's performance, when compared to all GPUs in the benchmark database, falls exactly in the middle, with 50% of GPUs performing better and 50% performing worse. This is a relative positioning, but without specific scores or rival names, it is impossible to state exact performance deltas or compare it to a named competitor.

The card's raw compute specifications provide an absolute measure of its capability. The FP32 performance is rated at 7.885 TFLOPS, which is a direct measure of single-precision floating-point throughput. The texture rate is 123.2 GTexel/s, and the pixel rate is 70.40 GPixel/s. These figures suggest a card that is capable of handling standard workstation tasks like 3D viewport rendering and photo editing, but which will struggle with heavy compute loads. The FP16 performance is identical to FP32 at 7.885 TFLOPS, indicating a 1:1 ratio, which is efficient for applications that can use half-precision arithmetic.

The lack of benchmark data means that any interpretation of the 50th percentile must be qualitative. It suggests that the W7400 is not a performance leader, but it is also not a bottom-tier card. In a professional context, this could mean it is adequate for entry-level tasks but will be outperformed by higher-end Radeon PRO or competitor cards. The card's 7.885 TFLOPS FP32 throughput is a moderate figure, and its 172.8 GB/s bandwidth is similarly mid-range. These specifications align with a card designed for mainstream professional use, not for high-performance computing or heavy rendering farms.

Power and Cooling

The AMD Radeon PRO W7400 has a remarkably low thermal design power (TDP) of just 55 W. This is exceptionally low for a GPU with 1792 shading units and 28 RT cores, indicating a highly power-efficient design. The card is specified as a single-slot solution, which is made possible by its low power draw. It does not require any external power connectors, drawing all its power from the PCIe slot. The suggested power supply for a system using this card is 250 W, which is a modest requirement that allows for integration into small form factor or low-power workstations.

The cooling solution is not explicitly detailed in the FACT PACK, but the single-slot design and 55 W TDP imply that a simple blower-style or passive heatsink can manage the thermal load. The card's dimensions are 168 mm in length, 69 mm in height, and 20 mm in width, making it a compact unit that fits easily into most chassis. The lack of power connectors simplifies installation and cable management, as no additional power cables need to be routed to the card. This makes the W7400 an ideal choice for systems where space is at a premium or where a quiet, low-power operation is desired.

The efficiency of the card is a key selling point, as it delivers modern features like ray tracing without the high power demands of larger GPUs. The 55 W TDP also means that heat dissipation is manageable, reducing the strain on system cooling. For professional users with multi-GPU configurations or dense workstations, the low power draw of each card allows for more GPUs to be installed without exceeding power or thermal limits. The 250 W PSU recommendation is a guideline for the overall system, ensuring stable operation even with a mid-range CPU and other components.

Memory Subsystem

The AMD Radeon PRO W7400 is equipped with 8 GB of GDDR6 memory, connected via a 128-bit memory bus. This configuration yields a total memory bandwidth of 172.8 GB/s. The memory operates at an effective speed of 10.8 Gbps, as indicated by the memory clock of 1350 MHz. This bandwidth is adequate for 1080p and 1440p workloads, where texture streaming and frame buffer operations are within the card's capacity. However, for 4K resolutions or scenes with very high-resolution textures, the 128-bit bus width may limit performance, as the bandwidth is not as high as cards with 256-bit or wider buses.

The 8 GB VRAM capacity is a significant factor for professional applications. It is sufficient for most CAD models, 3D scenes, and video editing timelines, but it can be a constraint for extremely large datasets or complex simulations that require more memory. The card's memory subsystem is also a point of comparison to its predecessor, the Radeon Pro Vega, which likely used a different memory configuration. The W7400's 172.8 GB/s bandwidth is moderate, and professional applications that are bandwidth-sensitive, such as high-resolution compositing or scientific visualization, may see performance limitations.

The memory type and capacity are well-suited for the card's target audience. The 8 GB GDDR6 is a standard amount for entry-level professional cards, providing enough memory for most tasks without inflating cost. The 128-bit bus is a trade-off, balancing cost and power against bandwidth. For users who need to work with 4K monitors or multi-monitor setups, the card can handle display output, but the memory bandwidth may become a bottleneck when rendering complex scenes at these resolutions. The 172.8 GB/s figure is a hard limit on data throughput, and applications that exceed this will see reduced frame rates or longer render times.
