AMD Radeon PRO W7800 vs NVIDIA L4 Comparison

The AMD Radeon PRO W7800 and NVIDIA L4 target very different corners of the professional GPU market, and the benchmark data reflects that split. The Radeon PRO W7800 is a workstation-class card built for maximum compute throughput, while the NVIDIA L4 is a low-power server accelerator designed for density and efficiency. In the two head-to-head benchmark tests available, the AMD card wins decisively, but the L4’s strengths lie elsewhere—specifically in its power envelope and server-oriented feature set. Below is a breakdown of what the data actually shows, without speculation.

Head-to-Head Benchmarks

The most striking result is in the Geekbench Vulkan test, where the AMD Radeon PRO W7800 scores 175,422 against the NVIDIA L4’s 121,306. That is a 44.6% advantage for AMD, a massive gap that indicates the Radeon PRO W7800 has significantly higher raw graphics and compute throughput in this API. In practical terms, this suggests the AMD card is better suited for workloads that leverage Vulkan’s low-level access to GPU hardware, such as certain rendering engines or compute applications that bypass higher-level abstraction layers.

The Geekbench OpenCL test is closer but still favors AMD. The Radeon PRO W7800 posts 154,366, while the NVIDIA L4 scores 140,838, giving AMD a 9.6% lead. OpenCL is often used for general-purpose GPU compute, and this narrower margin suggests that while the AMD card is faster, the NVIDIA L4 is not far behind in this particular workload. The L4’s 240 tensor cores may help in certain OpenCL compute tasks that utilize them, but the raw FP32 throughput of the AMD card—45.25 TFLOPS versus 30.29 TFLOPS—likely explains the overall lead.

Looking at the broader benchmark context, the Radeon PRO W7800’s average benchmark score is 164,894, which places it in the 97th percentile of all GPUs. Its nearest rivals include the NVIDIA RTX A5500 (165,217, just 0.2% higher) and the RTX 4500 Ada Generation (166,094, 0.7% higher), meaning the AMD card sits in a very tight competitive cluster at the top end. In contrast, the NVIDIA L4 has an average score of 131,072, putting it in the 95th percentile. Its nearest rivals are the GeForce RTX 3090 Ti (131,938, 0.7% higher) and the RTX 4000 Ada Generation (135,218, 3.1% higher). The L4 is clearly a step below the Radeon PRO W7800 in overall compute performance, but it is still a high-performing GPU in absolute terms.

The delta percentages in the head-to-head tests tell a clear story: AMD wins both tests, with the Vulkan margin being particularly lopsided. The data does not show a single benchmark where the NVIDIA L4 comes out ahead, so any discussion of the L4’s merits must focus on factors other than raw performance scores.

The Verdict

Based strictly on the benchmark data, the AMD Radeon PRO W7800 is the superior performer in both OpenCL and Vulkan workloads. If your priority is maximum compute throughput and you have the power budget and physical space for a dual-slot, 260 W card, the Radeon PRO W7800 is the clear choice from these two options. Its 44.6% lead in Vulkan and 9.6% lead in OpenCL are substantial, and its 97th percentile ranking among all GPUs underscores its high-end positioning.

However, the NVIDIA L4 is not without its own appeals, which are not captured in the benchmark scores. It draws only 72 W of power compared to the Radeon PRO W7800’s 260 W, and it requires no power connectors at all. It is a single-slot card measuring 169 mm in length, versus the Radeon PRO W7800’s 280 mm dual-slot design. For dense server deployments where power and space are at a premium, the L4’s efficiency may outweigh its lower performance. The L4 also has 240 tensor cores, which the AMD card lacks entirely, making it potentially more suitable for AI inference tasks that rely on tensor operations—though the benchmark data does not directly measure this.

The verdict depends on workload and environment. For a workstation where raw compute is king, choose the Radeon PRO W7800. For a low-power server environment where density and thermal limits are critical, the NVIDIA L4 is the pragmatic option. The data does not support any claim that the L4 is faster in general compute, but it does support the idea that the L4 is far more efficient.

Architecture Differences

The two GPUs are built on fundamentally different architectures. The AMD Radeon PRO W7800 uses the RDNA 3.0 architecture with the Navi 31 chip, codenamed Plum Bonito. It is fabricated on a 5 nm process by TSMC, with 57,700 million transistors on a 529 mm² die. The NVIDIA L4 uses the Ada Lovelace architecture with the AD104 chip, also on a 5 nm TSMC process, but with 35,800 million transistors on a 294 mm² die. This means the AMD chip has a lower transistor density (109.1M per mm²) compared to the L4 (121.8M per mm²), but the AMD die is significantly larger overall.

The core configurations differ sharply. The Radeon PRO W7800 has 4,480 shading units, 280 texture mapping units (TMUs), and 128 raster operation units (ROPs). It also includes 70 ray tracing cores. The NVIDIA L4 has 7,424 shading units, 240 TMUs, 80 ROPs, 60 ray tracing cores, and adds 240 tensor cores. The L4’s higher shading unit count is notable, yet its FP32 throughput is lower (30.29 TFLOPS versus 45.25 TFLOPS), which indicates a lower clock speed is the limiting factor. The L4’s base clock is 795 MHz and boost clock is 2040 MHz, while the Radeon PRO W7800 runs at 1895 MHz base and 2525 MHz boost.

Memory architecture also diverges. The Radeon PRO W7800 has 32 GB of GDDR6 on a 256-bit bus, yielding 576.0 GB/s of bandwidth. The NVIDIA L4 has 24 GB of GDDR6 on a 192-bit bus, with 300.1 GB/s of bandwidth. The AMD card’s memory clock is 2250 MHz (18 Gbps effective), while the L4’s is 1563 MHz (12.5 Gbps effective). The Radeon PRO W7800’s memory bandwidth advantage is nearly 2x, which is critical for data-heavy workloads.

The power and physical profiles are opposite extremes. The Radeon PRO W7800 consumes 260 W, requires two 8-pin power connectors, and needs a 600 W suggested PSU. It is a dual-slot card measuring 280 mm in length, 110 mm in height, and 40 mm in width. The NVIDIA L4 consumes just 72 W, has no power connectors, and requires only a 250 W suggested PSU. It is a single-slot card measuring 169 mm in length and 56 mm in height, with no width listed. The L4 also has no display outputs, making it strictly a compute server card, while the Radeon PRO W7800 offers 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1.

API support is identical: both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Radeon PRO W7800 was released on April 12, 2023, with a launch MSRP of 2,499 USD. The NVIDIA L4 was released on March 20, 2023, and has no listed launch MSRP. The Radeon PRO W7800’s predecessor is the Radeon Pro Vega, while the L4’s predecessor is Server Ampere and its successor is Server Hopper.

Where Each One Wins

The AMD Radeon PRO W7800 wins in every measured benchmark. It leads by 9.6% in OpenCL and 44.6% in Vulkan, and its average benchmark score of 164,894 is 25.8% higher than the L4’s 131,072. It also wins on memory: 32 GB versus 24 GB, and 576.0 GB/s versus 300.1 GB/s. For compute-heavy tasks like 3D rendering, scientific simulation, or any workload that scales with FP32 throughput and memory bandwidth, the Radeon PRO W7800 is the clear winner. Its 97th percentile ranking places it among the top GPUs, and its nearest rivals—the RTX A5500 and RTX 4500 Ada—are within 0.7% of its average score, meaning it is competitive with the best in its class.

The NVIDIA L4 wins on efficiency and form factor. Its 72 W power draw is 72% lower than the Radeon PRO W7800’s 260 W. It is a single-slot card at 169 mm long, versus the dual-slot 280 mm AMD card, making it far easier to fit in dense server chassis. It has no power connectors, simplifying installation, and its 250 W suggested PSU requirement means it can run in systems with much smaller power supplies. For AI inference or other tensor-based tasks, the L4’s 240 tensor cores provide a capability the AMD card lacks entirely. The L4’s 95th percentile ranking is still high, and its nearest rival, the RTX 3090 Ti, is only 0.7% ahead, so it is not a weak performer—it is just optimized for a different purpose.
