AMD Radeon RX 7400 OEM vs NVIDIA L4 Comparison

Head-to-Head Benchmarks

The database contains recorded benchmark results for the NVIDIA L4, but the AMD Radeon RX 7400 OEM has no benchmark entries in the recorded data. This makes a direct head-to-head comparison impossible on the basis of measured scores alone. The L4's average benchmark score is 131,072, which places it in the 95th percentile of all GPUs in the database. The RX 7400 OEM sits in the 50th percentile, though this figure is based on its overall classification rather than any recorded test scores.

The L4's nearest rivals in the database provide context for its measured performance. The NVIDIA GeForce RTX 3090 Ti averages 131,938, which is 0.7% higher than the L4's average. The NVIDIA RTX 4000 Ada Generation and NVIDIA A10M each average 135,218 and 135,230 respectively, both 3.1% ahead of the L4. The AMD Radeon PRO W6800 averages 135,396, 3.2% ahead. These deltas are small, indicating that the L4 sits in a tightly contested performance band near the top of the database.

The RX 7400 OEM's theoretical compute figures, however, are far lower. The L4 delivers 30.29 TFLOPS FP32, while the RX 7400 OEM delivers 7.885 TFLOPS. That is a substantial gap of roughly 22.4 TFLOPS. The L4 also has a higher pixel rate at 163.2 GPixel/s versus 70.40 GPixel/s, and a higher texture rate at 489.6 GTexel/s versus 123.2 GTexel/s. These are raw specification differences, not measured results, but they indicate a large performance disparity in favor of the L4.

Because the RX 7400 OEM has no benchmark scores, the data cannot confirm how its real-world performance compares to the L4. The specification sheet suggests it would trail significantly in compute-heavy workloads. The L4's recorded OpenCL score of 140,838 and Vulkan score of 121,306 further establish its capability in general-purpose and graphics compute tasks. The RX 7400 OEM has no comparable recorded scores to set against these figures.

FAQ

Q: Does the AMD Radeon RX 7400 OEM have any recorded benchmark scores?

A: No. The database lists no benchmarks for the RX 7400 OEM. Its average benchmark score is recorded as zero, and it has no nearest rivals listed. The NVIDIA L4, by contrast, has two recorded scores: 140,838 in Geekbench OpenCL and 121,306 in Geekbench Vulkan.

Q: What is the NVIDIA L4's performance percentile compared to all GPUs?

A: The L4 sits in the 95th percentile of all GPUs in the database. Its average benchmark score of 131,072 places it within 0.7% to 3.2% of its four nearest rivals, which include the RTX 3090 Ti, RTX 4000 Ada Generation, A10M, and Radeon PRO W6800.

Q: How do the FP32 compute figures compare between the two cards?

A: The NVIDIA L4 delivers 30.29 TFLOPS FP32, while the AMD Radeon RX 7400 OEM delivers 7.885 TFLOPS. Both cards also achieve their FP16 figures at a 1:1 ratio with FP32, so the L4's FP16 output is likewise 30.29 TFLOPS versus 7.885 TFLOPS for the RX 7400 OEM.

Q: What are the memory specifications for each card?

A: The RX 7400 OEM has 8 GB of GDDR6 on a 128-bit bus, providing 172.8 GB/s of bandwidth. The L4 has 24 GB of GDDR6 on a 192-bit bus, providing 300.1 GB/s of bandwidth. The L4's memory clock is 1563 MHz (12.5 Gbps effective), while the RX 7400 OEM's memory clock is 1350 MHz (10.8 Gbps effective).

Q: Do both cards support the same graphics APIs?

A: Yes. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This means they are equally current in terms of API feature support, despite their different architectures.

Q: What is the power consumption difference between the two cards?

A: The RX 7400 OEM has a TDP of 55 W and requires a single 6-pin power connector. The L4 has a TDP of 72 W and requires no power connectors. Both cards have a suggested PSU rating of 250 W and are single-slot designs.

The Verdict

The data clearly favors the NVIDIA L4 for anyone needing measured compute performance. Its 95th percentile ranking, average benchmark score of 131,072, and recorded OpenCL and Vulkan results demonstrate strong real-world capability. The RX 7400 OEM has no benchmark data, so its performance cannot be validated from the database. Its raw specifications, including 7.885 TFLOPS FP32 and 8 GB of memory, are far below the L4's 30.29 TFLOPS and 24 GB.

The L4 is the appropriate choice for compute-intensive workloads, server deployments, or any task where measured performance matters. Its nearest rivals, all within 3.2% of its average score, confirm it sits in a high-performance tier. The RX 7400 OEM, with its lower transistor count (13,300 million versus 35,800 million), smaller die (204 mm² versus 294 mm²), and lower theoretical throughput, is positioned for lighter duties.

The RX 7400 OEM does have advantages in power efficiency on paper. Its 55 W TDP is lower than the L4's 72 W, and its 167 mm length is slightly shorter than the L4's 169 mm. It also includes display outputs (1x HDMI 2.1a and 3x DisplayPort 2.1), while the L4 has no display outputs at all. For a card requiring direct display connectivity, the RX 7400 OEM is the only option of the two. But for raw compute, the L4 is the clear pick based on the recorded data.

Specification Differences

The two cards differ across nearly every specification category. The RX 7400 OEM uses a 128-bit memory bus with 8 GB of GDDR6, while the L4 uses a 192-bit bus with 24 GB of GDDR6. Memory bandwidth is 172.8 GB/s for the AMD card and 300.1 GB/s for the NVIDIA card. The L4's memory clock runs at 1563 MHz (12.5 Gbps effective), compared to 1350 MHz (10.8 Gbps effective) for the RX 7400 OEM.

Shading unit counts diverge significantly: the RX 7400 OEM has 1,792 shading units, while the L4 has 7,424. Texture mapping units number 112 on the AMD card versus 240 on the NVIDIA card. Render output units are 64 on the RX 7400 OEM and 80 on the L4. The L4 also has 60 ray tracing cores and 240 tensor cores, while the RX 7400 OEM has 28 ray tracing cores and no tensor cores.

Clock speeds differ as well. The RX 7400 OEM has a base clock of 330 MHz and a boost clock of 1100 MHz. The L4 has a base clock of 795 MHz and a boost clock of 2040 MHz. The L4's pixel rate is 163.2 GPixel/s versus 70.40 GPixel/s for the AMD card, and its texture rate is 489.6 GTexel/s versus 123.2 GTexel/s.

Physical and power specifications also differ. The RX 7400 OEM requires a 6-pin power connector, while the L4 requires none. Both have a 250 W suggested PSU and are single-slot cards. The RX 7400 OEM measures 167 mm (6.6 inches) in length; the L4 measures 169 mm (6.7 inches) in length and 56 mm (2.2 inches) in height. The RX 7400 OEM uses a PCIe 4.0 x8 interface, while the L4 uses PCIe 4.0 x16. The RX 7400 OEM has display outputs; the L4 has none.

Architecture Differences

The two cards come from different architectural families entirely. The AMD Radeon RX 7400 OEM uses the Navi 33 chip based on RDNA 3.0 architecture, with the codename "Hotpink Bonefish." It belongs to the Navi III (RX 7000) generation and was released in August 2025. Its predecessor is Navi II and its successor is Navi IV. The chip is manufactured on a 6 nm process at TSMC, with 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2 million per square millimeter.

The NVIDIA L4 uses the AD104 chip based on Ada Lovelace architecture. It belongs to the Server Ada (Lxx) generation and was released in March 2023. Its predecessor is Server Ampere and its successor is Server Hopper. The chip is manufactured on a 5 nm process at TSMC, with 35,800 million transistors on a 294 mm² die, yielding a transistor density of 121.8 million per square millimeter. The L4's production status is listed as active, while the RX 7400 OEM's production status is not recorded.

The architectural differences extend to feature sets. The L4 includes 240 tensor cores, which the RX 7400 OEM lacks entirely. This makes the L4 suitable for AI and machine learning workloads, a capability the AMD card cannot offer based on the recorded data. The L4 also has more than double the ray tracing cores: 60 versus 28. The RX 7400 OEM's RDNA 3.0 architecture is newer by release date, but the L4's Ada Lovelace design carries substantially more compute resources. The L4's transistor density is nearly double that of the RX 7400 OEM, reflecting the denser 5 nm process and larger chip.
