AMD Radeon Pro W5700X vs NVIDIA RTX A4500 Mobile Comparison

Head-to-Head Benchmarks

The recorded benchmark data shows a decisive performance gap between these two workstation-class GPUs. In the Geekbench OpenCL test, the NVIDIA RTX A4500 Mobile scores 105,307, while the AMD Radeon Pro W5700X manages only 43,810. That is a 140.4% advantage for the NVIDIA card, more than double the AMD result. The gap narrows somewhat in Geekbench Vulkan, but the NVIDIA RTX A4500 Mobile still wins by a substantial margin: 76,960 versus 45,246, a 70.1% difference.

The overall average benchmark scores reinforce this pattern. The NVIDIA RTX A4500 Mobile posts an average of 91,134, while the AMD Radeon Pro W5700X averages 54,828. That places the AMD card roughly 40% behind the NVIDIA card in aggregate compute performance. The percentile rankings tell a similar story: the NVIDIA part sits in the 93rd percentile among all GPUs, while the AMD part lands in the 87th percentile. Both are high performers, but the NVIDIA card is clearly in a different tier.

When comparing the AMD Radeon Pro W5700X to its nearest rivals in the database, the picture becomes more nuanced. Its average score of 54,828 sits within 1.1% of the NVIDIA GeForce RTX 4080 and RTX 4080 SUPER, and it trails the AMD Radeon RX 6750 GRE 12 GB by only 1.6%. These are consumer-oriented cards, yet the AMD workstation part matches them in raw compute. The NVIDIA RTX A4500 Mobile, by contrast, sits near the desktop RTX A4500, which scores 91,671, a mere 0.6% difference. That proximity suggests the mobile variant loses almost nothing to its desktop counterpart in these tests.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. NVIDIA's RTX A4500 Mobile uses the GA104 chip built on Samsung's 8 nm process, while AMD's Radeon Pro W5700X uses the Navi 10 chip fabricated by TSMC on a 7 nm node. The transistor counts reflect these differences: NVIDIA packs 17,400 million transistors into a 392 mm² die, yielding a density of 44.4 million transistors per square millimeter. AMD fits 10,300 million transistors into a smaller 251 mm² die, achieving 41.0 million per square millimeter. The TSMC 7 nm process allows AMD to pack more transistors per area than the older 8 nm node, but NVIDIA's larger die still holds far more total transistors.

Architecturally, NVIDIA employs the Ampere design with 5,888 shading units, 184 texture mapping units, and 96 raster operation pipelines. It also includes 46 dedicated ray tracing cores and 184 tensor cores, making it a fully featured modern compute accelerator. AMD's RDNA 1.0 architecture provides 2,560 shading units, 160 TMUs, and 64 ROPs, but it has no dedicated ray tracing cores and no tensor cores. The lack of these specialized units explains why the AMD card struggles in certain workloads, despite its higher boost clock of 2,040 MHz versus NVIDIA's 1,500 MHz boost.

Clock speeds tell an interesting story. AMD runs at a much higher frequency, with a base clock of 1,243 MHz and boost up to 2,040 MHz. NVIDIA's base is 930 MHz with a 1,500 MHz boost. Yet the NVIDIA card still dominates in raw throughput. This is because the FP32 compute rating for NVIDIA is 17.66 TFLOPS, while AMD delivers 10.44 TFLOPS. NVIDIA's massive shading unit count more than compensates for its lower clocks. In FP16, NVIDIA again offers 17.66 TFLOPS with a 1:1 ratio, while AMD reaches 20.89 TFLOPS but with a 2:1 ratio, meaning half the rate for full precision work.

Memory configurations are similar on paper, but the measured bandwidth differs. Both cards use 16 GB of GDDR6 on a 256-bit bus. NVIDIA runs its memory at 2,000 MHz with 16 Gbps effective transfer, producing 512.0 GB/s of bandwidth. AMD's memory runs at 1,750 MHz with 14 Gbps effective, yielding 448.0 GB/s. The NVIDIA card holds a 14.3% bandwidth advantage, which helps in memory-intensive rendering and compute tasks.

The Verdict

The data points to a clear winner for most professional workloads. The NVIDIA RTX A4500 Mobile beats the AMD Radeon Pro W5700X by 140.4% in OpenCL and 70.1% in Vulkan. Its average benchmark score of 91,134 versus 54,828 places it in a higher performance class entirely. The NVIDIA card also benefits from ray tracing cores and tensor cores, which the AMD card lacks entirely. For any task that leverages these accelerators, the choice is unambiguous.

However, the AMD Radeon Pro W5700X is not without merit. Its higher boost clock and superior texture fill rate of 326.4 GTexel/s versus NVIDIA's 276.0 GTexel/s suggest it could excel in certain texture-bound scenarios. The AMD card also has half the transistor count and a smaller die, which can imply different power characteristics, though the database shows AMD's TDP at 205 W versus NVIDIA's 140 W. The AMD part is a quad-slot card designed for Apple Mac Pro systems with an MPX interface, while the NVIDIA card is a mobile component with no dedicated power connectors. These are different tools for different platforms.

For users who need maximum compute performance in OpenCL or Vulkan, the NVIDIA RTX A4500 Mobile is the superior choice by every measured metric. The AMD card's only path to relevance is in specific Apple-centric workflows where its Metal API support and Thunderbolt outputs matter more than raw OpenCL scores.

A: The NVIDIA RTX A4500 Mobile is within 0.6% of the desktop NVIDIA RTX A4500 and 4.2% ahead of the NVIDIA Quadro GP100. The AMD Radeon Pro W5700X is within 1.1% of the GeForce RTX 4080 and trails the Radeon RX 6750 GRE by only 1.6%.

Where Each One Wins

The NVIDIA RTX A4500 Mobile wins in compute-heavy workloads that rely on OpenCL or Vulkan acceleration. Its 140.4% lead in OpenCL and 70.1% lead in Vulkan make it the obvious choice for rendering, simulation, and machine learning tasks that use these APIs. The inclusion of 46 ray tracing cores and 184 tensor cores means it can accelerate real-time ray tracing and AI inference, capabilities the AMD card simply does not have. Its higher memory bandwidth of 512.0 GB/s also benefits large dataset processing.

The AMD Radeon Pro W5700X wins in scenarios that favor its high boost clock and texture throughput. With 2,040 MHz boost versus NVIDIA's 1,500 MHz, the AMD card can process texture-heavy scenes faster, as evidenced by its 326.4 GTexel/s texture rate versus NVIDIA's 276.0 GTexel/s. Its FP16 capability of 20.89 TFLOPS, even at 2:1 ratio, gives it an edge in half-precision computing tasks. The card also supports Apple's MPX bus interface and provides 4x Thunderbolt outputs plus 1x HDMI 2.0b, making it the only choice for Mac Pro systems requiring these connections.

The AMD card's lower transistor count and smaller die size may also imply different thermal behavior, though the database lists its TDP at 205 W, which is higher than NVIDIA's 140 W. The quad-slot form factor suggests substantial cooling, but it also means the card requires significant physical space.
