AMD Radeon PRO W7600 vs NVIDIA L40 Comparison

Head-to-Head Benchmarks

The recorded benchmark data shows a decisive performance gap between the NVIDIA L40 and the AMD Radeon PRO W7600, with the L40 winning both head-to-head tests. In Geekbench OpenCL, the L40 scores 330,926 against 81,528 for the W7600, a delta of 305.9%. That is a massive margin, roughly four times the raw score of the AMD card. In Geekbench Vulkan, the L40 scores 237,295 versus 92,688, a delta of 156%. While the gap narrows in Vulkan, the L40 still more than doubles the W7600's result.

Context from the database's nearest rival comparisons helps interpret these numbers. The L40's average benchmark score is 284,111, placing it in the 99th percentile of all GPUs. Its closest rivals include the NVIDIA RTX 6000 Ada Generation at 287,237 (1.1% higher), the NVIDIA L40S at 295,763 (3.9% higher), the AMD Instinct MI300X at 317,994 (10.7% higher), and the NVIDIA L20 at 251,147 (13.1% lower). The W7600, by contrast, averages 87,108 and sits in the 93rd percentile. Its nearest rivals are all within a narrow band: the NVIDIA Quadro GP100 at 87,445 (0.4% higher), the NVIDIA CMP 40HX at 85,637 (1.7% lower), the NVIDIA RTX A4500 Mobile at 91,134 (4.4% higher), and the NVIDIA RTX A4500 at 91,671 (5.0% higher). In other words, the W7600 competes with an older generation of professional cards, while the L40 is operating in a completely different performance tier.

The OpenCL result is particularly telling. A 305.9% lead in OpenCL suggests the L40's compute resources are vastly larger, which aligns with its position among server-class accelerators. The Vulkan result, while still a clear win, shows the W7600's RDNA 3.0 architecture handling graphics-oriented workloads relatively better. Still, the L40's 156% lead in Vulkan leaves no ambiguity about which card is faster in absolute terms.

Architecture Differences

The two cards come from different design philosophies. The NVIDIA L40 uses the AD102 chip on the Ada Lovelace architecture, built on a 5 nm process at TSMC. It packs 76,300 million transistors on a 609 mm² die, giving a transistor density of 125.3M per mm². The AMD Radeon PRO W7600 uses the Navi 33 chip with RDNA 3.0 architecture, codenamed Hotpink Bonefish, on a 6 nm process also at TSMC. It has 13,300 million transistors on a 204 mm² die, with a density of 65.2M per mm². The L40's die is roughly three times larger and carries more than five times the transistor count.

The compute specifications reflect this chasm. The L40 has 18,176 shading units, 568 texture mapping units, 192 ROPs, 142 RT cores, and 568 tensor cores. The W7600 has 2,048 shading units, 128 TMUs, 64 ROPs, and 32 RT cores. The W7600 has no tensor cores listed. Pixel rate for the L40 is 478.1 GPixel/s versus 156.2 GPixel/s for the W7600. Texture rate is 1,414.3 GTexel/s versus 312.3 GTexel/s. FP32 throughput is 90.52 TFLOPS for the L40 and 19.99 TFLOPS for the W7600. FP16 is 90.52 TFLOPS (1:1) on the L40, while the W7600 delivers 39.98 TFLOPS (2:1).

Memory is another major divider. The L40 ships with 48 GB of GDDR6 on a 384-bit bus, providing 864.0 GB/s of bandwidth. The W7600 has 8 GB of GDDR6 on a 128-bit bus, with 288.0 GB/s. The L40 offers six times the capacity and three times the bandwidth. Clock speeds tell a different story: the W7600 has a higher base clock at 1720 MHz versus 735 MHz on the L40, but the boost clocks are close at 2440 MHz versus 2490 MHz. Memory clock is identical at 2250 MHz, or 18 Gbps effective. The L40's advantage comes from its massive parallel resources, not from higher frequencies.

Power and physical specs also differ sharply. The L40 has a 300 W TDP and requires a 700 W suggested PSU, with a dual-slot cooler and a single 16-pin connector. The W7600 has a 130 W TDP, a 300 W suggested PSU, a single-slot cooler, and a single 6-pin connector. The L40 is longer at 267 mm (10.5 inches) and shorter in height at 111 mm (4.4 inches), while the W7600 is 241 mm (9.5 inches) long and 115 mm (4.5 inches) tall. The L40 uses PCIe 4.0 x16, the W7600 uses PCIe 4.0 x8. Display outputs are both four ports, but the L40 has DisplayPort 1.4a while the W7600 has DisplayPort 2.1.

FAQ

Q: Which card has more memory, and why does it matter?

A: The NVIDIA L40 has 48 GB of GDDR6 on a 384-bit bus with 864.0 GB/s bandwidth. The AMD Radeon PRO W7600 has 8 GB on a 128-bit bus with 288.0 GB/s. Six times the capacity and three times the bandwidth means the L40 can handle far larger datasets entirely in VRAM, which matters for large model inference and large scene rendering workloads.

Q: How do the power requirements compare?

A: The L40 has a 300 W TDP and a 700 W suggested PSU. The W7600 has a 130 W TDP and a 300 W PSU. The W7600 is much lighter on power draw and can fit into systems with smaller power supplies, while the L40 needs a heftier PSU and is dual-slot.

Q: Is the W7600 competitive in any benchmark?

A: The W7600 does not win either recorded test. It trails by 305.9% in Geekbench OpenCL and by 156% in Geekbench Vulkan. Its only relative strength is that the Vulkan margin is smaller, indicating its graphics-oriented workload scaling is comparatively better than its compute scaling.

Q: What generation is each card from?

A: The L40 is from the Server Ada generation (Lxx), released on 2022-10-12. The W7600 is from the Radeon Pro Navi (Navi III Series) generation, released on 2023-08-02. The L40 is end-of-life with a successor in Server Hopper; the W7600 is active with no listed successor.

Q: What are the architectural differences in compute features?

A: The L40 uses Ada Lovelace with 142 RT cores and 568 tensor cores. The W7600 uses RDNA 3.0 with 32 RT cores and no tensor cores listed. The presence of tensor cores gives the L40 capabilities in AI-accelerated workloads that the W7600 lacks entirely.

Q: What is the performance percentile of each card?

A: The L40 sits in the 99th percentile of all GPUs with an average benchmark score of 284,111. The W7600 sits in the 93rd percentile with an average score of 87,108. The percentile gap reflects a difference of several performance tiers, not a minor step.

The Verdict

The data supports a clear split. The NVIDIA L40 is a server-class accelerator for workloads where raw compute, large memory capacity, and high bandwidth are non-negotiable. Its 99th percentile standing, 48 GB memory, 864.0 GB/s bandwidth, and 90.52 TFLOPS FP32 make it suitable for heavy compute tasks. Its nearest rivals are other high-end accelerators like the RTX 6000 Ada Generation and the AMD Instinct MI300X, which means anyone choosing the L40 is operating in that performance bracket.

The AMD Radeon PRO W7600 is a different tool entirely. With 8 GB memory, 288.0 GB/s bandwidth, 19.99 TFLOPS FP32, and a 130 W TDP, it is a low-power, single-slot professional card. Its nearest rivals are older NVIDIA professional cards like the Quadro GP100 and RTX A4500, which tells you it competes in a much lower performance tier. The 93rd percentile is respectable, but the gap to the L40 is enormous.

The launch MSRP of the W7600 is 599 USD. That is the only pricing data in the database, and it appears once here. The L40 has no recorded launch MSRP.

There is no scenario in the recorded data where the W7600 outperforms the L40. The question is whether you need the L40's capabilities at all. If your workloads fit within 8 GB of VRAM and do not require tensor cores, the W7600 is a far lighter system burden. If you need the L40's compute or memory class, the W7600 is not a substitute.

Where Each One Wins

The NVIDIA L40 wins every recorded benchmark, but its victories are not uniform. The 305.9% OpenCL lead indicates a massive compute advantage, which points to workloads like simulation, rendering, scientific computing, and any task that scales across thousands of shading units. The 156% Vulkan lead is smaller but still dominant. The 48 GB memory capacity and 864.0 GB/s bandwidth make the L40 the choice for datasets that cannot fit in smaller frames of VRAM. The tensor cores add capability for AI-adjacent workloads, though the database does not include a dedicated AI benchmark. The 99th percentile overall ranking places it among the top accelerators in the database.

The AMD Radeon PRO W7600 does not win any recorded benchmark, but it has structural advantages that matter in specific deployments. Its 130 W TDP and 300 W suggested PSU mean it can go into systems where the L40's 700 W PSU requirement is impossible. The single-slot design and 241 mm length let it fit into compact chassis. The 6-pin power connector is universally compatible. DisplayPort 2.1 outputs are a generation newer than the L40's DisplayPort 1.4a. Its 93rd percentile still puts it above the majority of GPUs in the database, and its nearest rivals include capable cards like the RTX A4500. For a workstation that needs professional drivers, 8 GB of VRAM, and low power draw, the W7600 is a rational pick. For anything requiring the L40's compute, memory, or bandwidth class, the data says the L40 is the only option of the two.

The production statuses reinforce the positioning. The L40 is end-of-life with a successor in Server Hopper; the W7600 is active with no successor listed. This suggests the L40 is at the tail end of its lifecycle, while the W7600 is current. Buyers should weigh that against the vast performance difference. The database records no scenario where the W7600's newer release or lower power draw translates into a benchmark win.
