AMD Radeon AI PRO 9600D vs NVIDIA L4 Comparison

The Verdict

The database comparison between the AMD Radeon AI PRO 9600D and the NVIDIA L4 presents a stark contrast in positioning. The NVIDIA L4 holds the 95th percentile among all GPUs, while the AMD Radeon AI PRO 9600D sits at the 50th percentile. The L4's recorded average benchmark score is 131,072, derived from Geekbench OpenCL and Vulkan tests, whereas the AMD card has no recorded benchmark scores in the database. This absence of data means the AMD card cannot be directly positioned against the L4 in raw performance metrics.

The L4 delivers 30.29 TFLOPS of FP32 compute, while the AMD card offers 24.82 TFLOPS. The NVIDIA card also leads in texture rate at 489.6 GTexel/s versus 387.8 GTexel/s. However, the AMD Radeon AI PRO 9600D counters with 32 GB of GDDR6 memory on a 256-bit bus, producing 576.0 GB/s of bandwidth, compared to the L4's 24 GB on a 192-bit bus with 300.1 GB/s. The AMD card also has a higher pixel rate at 193.9 GPixel/s versus 163.2 GPixel/s.

The data indicates the NVIDIA L4 is the stronger general-purpose compute accelerator, particularly for workloads that benefit from higher FP32 throughput and tensor core processing. The AMD card appears oriented toward memory-capacity-sensitive workloads, where its 32 GB frame buffer and wider memory bus provide a clear advantage. Users requiring the highest raw compute density should select the L4, while those needing larger on-board memory for large datasets should consider the AMD offering.

Where Each One Wins

The NVIDIA L4 wins decisively in raw compute throughput. Its 30.29 TFLOPS FP32 output exceeds the AMD card's 24.82 TFLOPS by roughly 22 percent. The L4 also processes textures faster, with 489.6 GTexel/s versus 387.8 GTexel/s, a 26 percent advantage. The L4's 2040 MHz boost clock outpaces the AMD card's 2020 MHz boost, and its 7424 shading units dwarf the AMD card's 3072 units. The L4 also includes 240 tensor cores and 60 RT cores, while the AMD card's tensor core count is not listed, leaving a capability gap for AI inference and ray tracing workloads.

The AMD Radeon AI PRO 9600D wins in memory capacity and bandwidth. Its 32 GB GDDR6 frame buffer provides 33 percent more memory than the L4's 24 GB. The 256-bit bus delivers 576.0 GB/s, which is 92 percent higher than the L4's 300.1 GB/s. The AMD card also has a higher pixel rate (193.9 GPixel/s versus 163.2 GPixel/s), indicating faster fill-rate performance for rasterization-heavy tasks. The AMD card's 48 RT cores trail the L4's 60, but its 192 TMUs and 96 ROPs provide a balanced texture and pixel pipeline.

Power consumption tells a different story. The NVIDIA L4 draws only 72 W TDP and requires no power connectors, while the AMD card demands 150 W TDP and a 16-pin connector. The L4's suggested PSU is 250 W versus 450 W for the AMD card. This makes the L4 far more efficient for dense server deployments where power density is a constraint.

Architecture Differences

The two cards come from different architectural lineages. The AMD Radeon AI PRO 9600D uses the Navi 48 chip built on RDNA 4.0 architecture, manufactured on a 4 nm process at TSMC. The NVIDIA L4 uses the AD104 chip built on Ada Lovelace architecture, manufactured on a 5 nm process at TSMC. The AMD card belongs to the Radeon Pro Navi (Navi IV Series) generation, while the L4 is part of the Server Ada (Lxx) generation.

Transistor counts differ substantially. The AMD chip packs 53,900 million transistors on a 357 mm² die, yielding a density of 151.0M transistors per mm². The NVIDIA chip contains 35,800 million transistors on a 294 mm² die, with a density of 121.8M per mm². The AMD chip's smaller process node allows for higher transistor density despite the larger die.

Memory architecture diverges clearly. The AMD card uses 32 GB of GDDR6 on a 256-bit bus with 576.0 GB/s bandwidth. The NVIDIA L4 uses 24 GB of GDDR6 on a 192-bit bus with 300.1 GB/s bandwidth. The AMD card's memory clock operates at 2250 MHz (18 Gbps effective), while the L4's memory runs at 1563 MHz (12.5 Gbps effective).

Interface and physical specifications also differ. The AMD card uses PCIe 5.0 x16, while the L4 uses PCIe 4.0 x16. The AMD card measures 241 mm in length, 111 mm in height, and 19 mm in width. The L4 is much smaller at 169 mm long and 56 mm high. Both are single-slot cards. The AMD card provides one DisplayPort 2.1a output, while the L4 has no display outputs, reflecting its server-oriented design.

Feature sets align on API support. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD card's RDNA 4.0 architecture provides ray tracing capabilities through its 48 RT cores, while the L4's Ada Lovelace architecture includes 60 RT cores and 240 tensor cores, the latter being absent from the AMD card's listed specifications.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between these two cards, and the AMD Radeon AI PRO 9600D has no individual benchmark scores. The NVIDIA L4, however, has two recorded Geekbench results. Its OpenCL score of 140,838 and Vulkan score of 121,306 produce an average of 131,072. This places the L4 in the 95th percentile of all GPUs, a position that reflects strong overall compute capability.

The L4's nearest rivals provide context for its performance tier. The NVIDIA GeForce RTX 3090 Ti averages 131,938, which is 0.7 percent higher than the L4's average, making the L4 effectively a peer of that card. The NVIDIA RTX 4000 Ada Generation averages 135,218, 3.1 percent higher than the L4. The NVIDIA A10M also averages 135,230, again 3.1 percent higher. The AMD Radeon PRO W6800 averages 135,396, 3.2 percent higher. These figures indicate the L4 sits just below a cluster of high-end workstation and server cards, while remaining competitive with the RTX 3090 Ti.

Since the AMD Radeon AI PRO 9600D lacks recorded benchmark scores, its 50th percentile ranking reflects a mid-tier positioning based on its specifications. The FP32 gap between the two cards is 5.47 TFLOPS in favor of the L4, a 22 percent difference. The texture rate gap is 101.8 GTexel/s in favor of the L4, a 26 percent difference. The memory bandwidth gap is 275.9 GB/s in favor of the AMD card, a 92 percent difference.

The pixel rate comparison favors the AMD card by 30.7 GPixel/s, with 193.9 GPixel/s versus 163.2 GPixel/s, an 18.8 percent advantage. The AMD card's 192 TMUs are fewer than the L4's 240, but its 96 ROPs outnumber the L4's 80. The L4's 7424 shading units are more than double the AMD card's 3072, explaining its higher FP32 output despite a lower base clock of 795 MHz versus 1080 MHz.

Clock speeds reveal different operational profiles. The AMD card runs at 1080 MHz base and 2020 MHz boost, while the L4 runs at 795 MHz base and 2040 MHz boost. The AMD card's higher base clock suggests better sustained performance at lower loads, while the L4's higher boost clock allows it to reach peak performance under full load. The L4 achieves this with a 72 W TDP, less than half the AMD card's 150 W TDP.

The transistor density difference reflects process node maturity. The AMD card's 4 nm process enables 151.0M transistors per mm², while the L4's 5 nm process achieves 121.8M per mm². Despite the AMD card having 18,100 million more transistors, the L4 delivers higher compute throughput, indicating architectural efficiency differences between RDNA 4.0 and Ada Lovelace.

Physical size favors the L4 for dense deployments. The L4 measures 169 mm in length and 56 mm in height, while the AMD card measures 241 mm in length and 111 mm in height. Both are single-slot designs, but the L4's compact footprint and lack of power connectors make it easier to install in space-constrained servers. The AMD card requires PCIe 5.0 x16 connectivity, while the L4 operates on PCIe 4.0 x16, which may limit the AMD card's compatibility with older server platforms.

The L4's 240 tensor cores provide dedicated AI acceleration hardware that the AMD card lacks in the recorded specifications. This makes the L4 suitable for inference workloads, while the AMD card's larger memory capacity could support larger batch sizes or models, but without tensor cores, its AI processing efficiency would likely be lower. The L4's 60 RT cores also exceed the AMD card's 48, giving the NVIDIA card an advantage in ray-traced rendering workloads.
