AMD Radeon PRO W7600 vs NVIDIA RTX A4500 Mobile Comparison

# NVIDIA RTX A4500 Mobile vs AMD Radeon PRO W7600

The NVIDIA RTX A4500 Mobile and AMD Radeon PRO W7600 are both professional-grade workstation GPUs that land in the 93rd percentile of all GPUs, yet they approach performance from opposite directions. The NVIDIA card, an Ampere-generation mobile part with 16 GB of memory, edges out the AMD card in average benchmark score (91,134 vs. 87,108, a 4.6% gap), but the AMD Radeon PRO W7600 strikes back decisively in Vulkan workloads. The data suggests these are not direct substitutes but rather complementary tools: one prioritizes raw compute throughput and memory capacity, while the other leverages a newer, denser architecture and faster clock speeds for API-specific advantages.

The Verdict

From the benchmark data, the NVIDIA RTX A4500 Mobile is the stronger overall performer, with an average benchmark score of 91,134 that places it 4.6% ahead of the AMD Radeon PRO W7600's 87,108. This lead is driven almost entirely by the NVIDIA card's dominant OpenCL result: 105,307 vs. 81,528, a 29.2% advantage. For professionals running OpenCL-based compute workloads, data science tasks, or rendering pipelines that rely on this API, the RTX A4500 Mobile is the clear choice. Its 16 GB of GDDR6 memory on a 256-bit bus (512.0 GB/s bandwidth) also provides double the capacity and 77.8% more bandwidth than the AMD card's 8 GB on 128-bit (288.0 GB/s), which matters for large datasets and high-resolution textures.

However, the AMD Radeon PRO W7600 wins the Vulkan benchmark decisively: 92,688 vs. 76,960, a 17% margin in its favor. This suggests that for Vulkan-based applications—many modern game engines, real-time visualization tools, and certain CAD packages—the AMD card delivers superior frame throughput. The W7600 also offers 19.99 TFLOPS of FP32 compute versus the RTX A4500 Mobile's 17.66 TFLOPS, a 13.2% raw compute advantage. Users whose workflows are Vulkan-centric or who prioritize raw FP32 throughput should lean toward the AMD card. The RTX A4500 Mobile is end-of-life, while the W7600 remains active, which may influence long-term driver support and availability decisions.

Architecture Differences

The two GPUs represent fundamentally different design philosophies. The NVIDIA RTX A4500 Mobile uses the GA104 chip built on Samsung's 8 nm process, packing 17,400 million transistors into a 392 mm² die (44.4M transistors per mm²). It is based on the Ampere architecture, which employs a 1:1 FP16 to FP32 ratio—both are 17.66 TFLOPS—and includes dedicated tensor cores (184) and ray tracing cores (46). The card features 5,888 shading units, 184 texture mapping units, and 96 ROPs, with a boost clock of 1500 MHz and a base clock of 930 MHz.

The AMD Radeon PRO W7600, in contrast, uses the Navi 33 chip on TSMC's 6 nm process, with 13,300 million transistors on a much smaller 204 mm² die (65.2M transistors per mm²). This higher transistor density reflects the newer RDNA 3.0 architecture (codename "Hotpink Bonefish"). The AMD card has fewer shading units (2,048) but runs at dramatically higher clocks: 2440 MHz boost and 1720 MHz base. It offers 19.99 TFLOPS of FP32 and 39.98 TFLOPS of FP16 (2:1 ratio), meaning it can double FP16 throughput where the NVIDIA card cannot. The W7600 includes 32 ray tracing cores but no tensor cores, and its memory runs at 18 Gbps effective versus 16 Gbps on the NVIDIA card. The AMD part is a single-slot card with a 6-pin power connector and a 300 W suggested PSU, while the NVIDIA mobile part draws 140 W and uses no external power connectors.

Specification Differences

The two cards differ across nearly every major specification category. The NVIDIA RTX A4500 Mobile uses the GA104 chip on Samsung's 8 nm process, while the AMD Radeon PRO W7600 uses the Navi 33 chip on TSMC's 6 nm process. Transistor counts differ: 17,400 million for NVIDIA versus 13,300 million for AMD, with die sizes of 392 mm² and 204 mm² respectively. Transistor density is notably higher on the AMD card: 65.2M/mm² versus 44.4M/mm².

Clock speeds show a significant divergence. The NVIDIA card has a 930 MHz base and 1500 MHz boost, while the AMD card runs at 1720 MHz base and 2440 MHz boost. Memory clocks differ as well: 2000 MHz (16 Gbps effective) for NVIDIA versus 2250 MHz (18 Gbps effective) for AMD. Memory configuration is starkly different: 16 GB on a 256-bit bus for NVIDIA versus 8 GB on a 128-bit bus for AMD, resulting in 512.0 GB/s versus 288.0 GB/s bandwidth.

Compute resources vary widely. The NVIDIA part has 5,888 shading units, 184 TMUs, 96 ROPs, 46 RT cores, and 184 tensor cores. The AMD part has 2,048 shading units, 128 TMUs, 64 ROPs, and 32 RT cores, with no tensor cores. Pixel rates are 144.0 GPixel/s for NVIDIA and 156.2 GPixel/s for AMD; texture rates are 276.0 GTexel/s for NVIDIA and 312.3 GTexel/s for AMD. FP32 performance favors AMD (19.99 TFLOPS vs. 17.66 TFLOPS), as does FP16 (39.98 TFLOPS vs. 17.66 TFLOPS).

Power and physical specs diverge: the NVIDIA card is a mobile part at 140 W with no power connectors, while the AMD card is a single-slot desktop part at 130 W with one 6-pin connector and a 300 W suggested PSU. The bus interface also differs: PCIe 4.0 x16 for NVIDIA versus PCIe 4.0 x8 for AMD. Display outputs are "portable device dependent" for NVIDIA versus 4x DisplayPort 2.1 for AMD. The AMD card has specific dimensions (241 mm length, 115 mm height), while NVIDIA lists none. The launch MSRP for the AMD card is 599 USD; the NVIDIA card has no listed launch MSRP.

Head-to-Head Benchmarks

The two benchmark results paint a clear picture of API-dependent performance. In the Geekbench OpenCL test, the NVIDIA RTX A4500 Mobile scores 105,307 against the AMD Radeon PRO W7600's 81,528. This 29.2% delta is the largest performance gap between the two cards in either test. The NVIDIA card's advantage here likely stems from its higher memory bandwidth (512.0 GB/s versus 288.0 GB/s) and larger memory pool (16 GB versus 8 GB), which allows it to move data more efficiently in compute-heavy OpenCL workloads. The 5,888 shading units, while clocked lower, provide more parallel execution resources for this type of workload.

The Geekbench Vulkan test flips the script completely. The AMD Radeon PRO W7600 scores 92,688, beating the NVIDIA RTX A4500 Mobile's 76,960 by 17%. This is a substantial reversal that underscores the architectural differences between RDNA 3.0 and Ampere. The AMD card's much higher boost clock (2440 MHz versus 1500 MHz) and higher FP32 throughput (19.99 TFLOPS versus 17.66 TFLOPS) appear to give it a decisive edge in Vulkan's more driver-efficient, lower-overhead API environment. The AMD card also benefits from its 2:1 FP16 ratio, which can accelerate certain Vulkan shader operations.

The overall average benchmark scores—91,134 for NVIDIA and 87,108 for AMD—reflect a 4.6% NVIDIA lead, but the distribution is uneven. In relative terms, the NVIDIA card's OpenCL win is worth nearly 30%, while the AMD card's Vulkan win is 17%. This means the choice between these two cards depends heavily on the primary API used by the target applications. The NVIDIA RTX A4500 Mobile's nearest rival data shows it performing close to the desktop RTX A4500 (91,671, only 0.6% higher) and ahead of the Quadro GP100 (87,445, a 4.2% delta). The AMD W7600 sits just behind the Quadro GP100 (87,445, a 0.4% delta) and ahead of the CMP 40HX (85,637, a 1.7% delta). The head-to-head between these two cards shows the NVIDIA part winning one test and the AMD part winning the other, with the NVIDIA card taking the aggregate score.
