AMD Radeon RX 7400

The AMD Radeon RX 7400 enters the Radeon RX 7000 series as a compact, low-power implementation of the Navi 33 chip, built on TSMC’s 6 nm process. With 13,300 million transistors packed into a 204 mm² die, this card targets a specific performance tier, sitting at the 50th percentile of all GPUs. The data sheet shows a boost clock of 2300 MHz, a game clock of 2200 MHz, and a base clock of 1452 MHz, delivering 16.49 TFLOPS of FP32 compute. This places it as a mid-pack performer, neither a flagship nor an entry-level part, with its 8 GB GDDR6 memory and 288.0 GB/s bandwidth shaping its behavior at higher resolutions.

Benchmark Performance

The fact pack lists no absolute benchmark scores and no nearestRivals data, so the analysis must rely on the available structural metrics. The 16.49 TFLOPS of FP32 throughput, combined with a pixel rate of 147.2 GPixel/s and a texture rate of 257.6 GTexel/s, suggests a card built for 1080p gaming with headroom for some 1440p titles. The 50th percentile ranking is the key comparative anchor: exactly half of all GPUs in the database score higher, and half score lower. This places the RX 7400 in the median tier, meaning it will outperform integrated graphics and older entry-level discrete cards, but it will lag behind high-end models that typically occupy the 75th percentile and above.

The FP16 rate of 32.97 TFLOPS (2:1 ratio) indicates that the card can double its compute throughput in workloads that support FP16, which is relevant for certain compute tasks but less so for standard rasterization. The 16.49 TFLOPS FP32 figure, when interpreted against the 50th percentile, implies that games at 1080p with medium-to-high settings should see playable frame rates, while 4K gaming will likely strain the memory subsystem and shading resources. The 64 ROPs and 112 TMUs provide a balanced rasterization pipeline, but the 8 GB VRAM becomes a limiting factor at higher resolutions, where texture demands exceed capacity. Benchmark results would likely show a steep drop-off from 1080p to 4K, consistent with the card’s mid-tier positioning.

Who Should Consider It

Based on the 50th percentile ranking and the 8 GB memory configuration, this card is best suited for gamers who primarily play at 1080p resolution. The 288.0 GB/s bandwidth and 128-bit bus width are adequate for 1080p textures, and the 16.49 TFLOPS compute should handle most modern titles at high settings without requiring aggressive upscaling. For 1440p, the card may still be viable for esports titles or older games, but users should expect to lower settings to maintain smooth frame rates, as the 8 GB VRAM could become a bottleneck in texture-heavy scenes. 4K gaming is not recommended; the 64 ROPs and 147.2 GPixel/s fill rate are insufficient for the pixel throughput required at that resolution, and the 8 GB memory will likely cause stuttering or texture pop-in.

The 43 W TDP is exceptionally low, which means the card can be installed in small-form-factor systems or pre-built desktops with modest power supplies. The dual-slot cooler and single 6-pin connector make installation straightforward in most cases. Users who prioritize energy efficiency over raw performance will find this card appealing, as its power draw is a fraction of higher-tier models. Conversely, enthusiasts seeking high-refresh-rate 1440p or 4K experiences should look elsewhere, as the data indicates this card is tuned for mainstream 1080p workloads.

How It Compares

The fact pack does not provide any nearestRivals entries, so direct percentage deltas against specific competitor cards cannot be stated. However, the 50th percentile ranking offers a general comparison framework. Against the broader Radeon RX 7000 series, this card sits below the higher-end Navi 33 variants that likely occupy higher percentiles, given their increased shading units and memory bandwidth. The 1792 shading units and 28 RT cores suggest a significantly lower compute density compared to the top of the series, which would translate to a substantial performance gap in both rasterization and ray tracing workloads.

Without rival data, the comparison must be qualitative: the RX 7400 is positioned as a budget-oriented part within its own generation, likely trading blows with previous-generation mid-range cards rather than current-generation flagships. The 6 nm process and 13,300 million transistors indicate a modern design, but the modest clock speeds and memory configuration cap its potential. The absence of a launch MSRP further complicates direct value comparisons, but the hardware profile suggests it competes in the entry-level discrete GPU segment, where 1080p performance is the primary criterion.

Ray Tracing and Feature Set

The RX 7400 includes 28 RT cores, a modest count that reflects its mid-tier positioning. Ray tracing performance will be functional but not class-leading; the 16.49 TFLOPS FP32 compute and 288.0 GB/s bandwidth will constrain ray-traced scenes, particularly at higher resolutions. The card supports DirectX 12 Ultimate (12_2), which means it can run hardware-accelerated ray tracing in supported titles, as well as Vulkan 1.4 and OpenGL 4.6. The absence of tensor cores (null in the fact pack) means that AI-based upscaling technologies that rely on dedicated tensor hardware are not available, though the card may still support other forms of upscaling through shader-based methods.

The feature set is otherwise standard for the RDNA 3.0 architecture, with support for HDMI 2.1a and DisplayPort 2.1 outputs, enabling high refresh rates on compatible displays. The 28 RT cores will provide a baseline ray tracing experience, but users should expect to use hybrid rendering or lower ray tracing settings to maintain playable frame rates. The 50th percentile ranking suggests that the card handles traditional rasterization well, but the ray tracing performance will lag behind cards with more RT cores, which typically occupy higher percentiles.

Power and Cooling

The RX 7400 has a remarkably low TDP of 43 W, making it one of the most power-efficient discrete GPUs in its class. The suggested PSU is 200 W, which means even modest power supplies can support this card without issue. The power connector requirement is a single 6-pin, which is widely compatible with existing power supplies. The dual-slot cooling solution should be more than adequate for the 43 W heat output, likely running quiet and cool under load. This low power draw also makes the card suitable for small-form-factor builds or systems with limited cooling capacity.

The 6 nm process node from TSMC contributes to this efficiency, as does the relatively low transistor count of 13,300 million. The compact die size of 204 mm² further aids in thermal management. Users upgrading from older, power-hungry GPUs will notice a significant reduction in system power draw and heat generation. The 200 W PSU recommendation is conservative, and most systems with a quality 200 W or higher PSU will operate this card without issue, leaving ample headroom for the rest of the system components.

Memory Subsystem

The RX 7400 is equipped with 8 GB of GDDR6 memory, running at an effective speed of 18 Gbps, which yields a bandwidth of 288.0 GB/s across a 128-bit bus. This memory configuration is a key differentiator for the card’s performance profile. At 1080p, 8 GB is generally sufficient for most games, though titles with high-resolution texture packs may approach the limit. The 288.0 GB/s bandwidth is adequate for 1080p and light 1440p workloads, but it will become a bottleneck in 4K scenarios where the memory bus width and bandwidth are insufficient to feed the shader units efficiently.

The 128-bit bus width is narrower than what higher-tier cards use, which limits the card’s ability to handle large data transfers. For 1440p gaming, users may need to reduce texture quality or rely on dynamic resolution scaling to stay within the 8 GB memory footprint. The 147.2 GPixel/s pixel rate and 257.6 GTexel/s texture rate are well-matched to the memory bandwidth, indicating a balanced design for its target resolution. However, the 8 GB capacity is the most likely limitation for future games, as VRAM requirements continue to grow. For users planning to keep the card for several years, the memory subsystem may force compromises in newer, more demanding titles.
