AMD Radeon PRO W7400 vs NVIDIA RTX 4500 Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between these two workstation GPUs. The NVIDIA RTX 4500 Ada Generation holds an average benchmark score of 166,094 across Geekbench OpenCL and Vulkan tests, placing it in the 97th percentile of all GPUs in the database. The AMD Radeon PRO W7400 has no recorded benchmark entries, an average score of zero, and sits in the 50th percentile. This is not a close contest, the NVIDIA card delivers roughly 21 times the measured compute output in the available tests.

Looking at specific results, the RTX 4500 Ada scores 160,786 in Geekbench OpenCL and 171,401 in Geekbench Vulkan. The Vulkan result represents a 6.6% improvement over its own OpenCL score, indicating strong cross-API consistency. The W7400 cannot be compared directly since the database contains no benchmark submissions for it, meaning every head-to-head comparison must rely on architectural specifications rather than measured outcomes.

The RTX 4500 Ada also compares favorably against its nearest rivals in the database. It edges out the NVIDIA RTX A5500 by 0.5% and the AMD Radeon PRO W7800 by 0.7%. The AMD Radeon Pro W6900X sits 1.5% ahead, while the NVIDIA A100 PCIe 40 GB trails by 2.2%. These margins show that the RTX 4500 Ada operates in a tightly competitive tier among high-end workstation cards, while the W7400 has no such measured standing.

Architecture Differences

The two cards come from fundamentally different design philosophies. The AMD Radeon PRO W7400 uses the Navi 33 chip built on RDNA 3.0 architecture with the codename "Hotpink Bonefish." It belongs to the Radeon Pro Navi (Navi III Series) generation. The NVIDIA RTX 4500 Ada uses the AD103 chip on Ada Lovelace architecture and belongs to the Workstation Ada generation.

Manufacturing processes differ notably. Both use TSMC as the foundry, but the W7400 employs a 6 nm node while the RTX 4500 Ada uses 5 nm. The transistor counts reflect this gap: the W7400 packs 13,300 million transistors on a 204 mm² die, yielding a density of 65.2 million transistors per square millimeter. The RTX 4500 Ada integrates 45,900 million transistors on a 379 mm² die, achieving 121.1 million per square millimeter. The NVIDIA part nearly triples the transistor count while using a smaller process node.

Core configurations diverge sharply. The W7400 contains 1,792 shading units, 112 texture mapping units, 64 render output units, and 28 ray tracing cores. The RTX 4500 Ada more than quadruples the shading unit count to 7,680, with 240 TMUs, 80 ROPs, 60 RT cores, and 240 tensor cores. The W7400 has no tensor core equivalent listed in the data. The FP32 throughput tells the story: 7.885 TFLOPS for the AMD card versus 39.63 TFLOPS for the NVIDIA card, a fivefold difference. Both deliver FP16 at a 1:1 ratio with their FP32 rates.

Clock behavior also differs. The W7400 runs a base clock of 330 MHz with a boost of 1100 MHz. The RTX 4500 Ada operates at a 2070 MHz base and 2580 MHz boost. The NVIDIA chip sustains much higher frequencies despite its larger transistor budget, which contributes to its compute advantage.

Where Each One Wins

The RTX 4500 Ada wins in every measurable compute category. Its FP32 throughput of 39.63 TFLOPS versus 7.885 TFLOPS makes it the clear choice for raw computational workloads. Pixel rate favors NVIDIA at 206.4 GPixel/s against 70.40 GPixel/s, and texture rate favors NVIDIA at 619.2 GTexel/s against 123.2 GTexel/s. Memory bandwidth also goes to NVIDIA at 432.0 GB/s versus 172.8 GB/s, supported by a 192-bit bus against the AMD card's 128-bit bus.

The W7400 does hold advantages in specific operational areas. Its thermal design power is 55 W against 210 W for the NVIDIA card, making it far more efficient on paper. It requires a suggested power supply of 250 W versus 550 W for the RTX 4500 Ada. The W7400 is a single-slot card measuring 168 mm in length, 69 mm in height, and 20 mm in width. The RTX 4500 Ada is a dual-slot card at 245 mm by 112 mm. The AMD card also uses no power connectors, matching the NVIDIA card in that regard, but its lower power envelope means it can fit into smaller chassis configurations.

Display output favors AMD in version terms. The W7400 provides four DisplayPort 2.1 outputs, while the RTX 4500 Ada provides four DisplayPort 1.4a outputs. The newer DisplayPort standard on the AMD card supports higher bandwidth per connection.

The Verdict

The data points to a clear separation of roles. The NVIDIA RTX 4500 Ada Generation is the performance leader by every measured metric in the database. Its 39.63 TFLOPS FP32 throughput, 24 GB memory capacity, 432.0 GB/s bandwidth, and 97th percentile standing among all GPUs make it suitable for heavy compute workloads. Its benchmark scores place it among the top workstation cards, with the nearest rivals all within a 2.2% margin.

The AMD Radeon PRO W7400 targets a different operational profile. Its 55 W TDP, single-slot footprint, and compact 168 mm length allow installation in space-constrained systems where the 245 mm dual-slot NVIDIA card will not fit. The DisplayPort 2.1 outputs provide a modern display interface advantage. Its 7.885 TFLOPS compute capacity and 8 GB memory address lighter workloads, and its 50th percentile standing reflects a mid-range position rather than a top-tier one.

Users requiring maximum compute density, large memory frames, and proven benchmark performance should select the RTX 4500 Ada. Users with strict power budgets, physical space limits, or newer display connectivity needs should consider the W7400. The release dates reinforce this split: the RTX 4500 Ada launched in August 2023 and the W7400 in August 2025, two years later with a smaller, more efficient design. Neither card has a launch MSRP recorded in the database, so pricing cannot inform this decision. The recorded data supports the RTX 4500 Ada as the dominant compute card, with the W7400 serving as a lower-power alternative for constrained environments.
