AMD Radeon PRO W7600 vs NVIDIA RTX A4500 Comparison

The NVIDIA RTX A4500 and AMD Radeon PRO W7600 are both professional workstation graphics cards aimed at similar use cases, yet they represent fundamentally different design philosophies and performance tiers. The data shows the RTX A4500 holds a decisive average benchmark score lead of 91,671 versus 87,108 for the Radeon PRO W7600, a 5.2% advantage from the perspective of the NVIDIA card. However, the two cards are separated by more than just raw compute, with significant differences in memory capacity, power requirements, and API feature support that will influence which card is the better fit for specific professional workloads.

Where Each One Wins

The RTX A4500 is the clear winner in every head-to-head benchmark recorded. In Geekbench OpenCL, the A4500 scores 141,837 against the W7600’s 81,528, a massive 74% delta. This is not a marginal victory; it indicates that in compute-heavy OpenCL workloads, the A4500 delivers substantially higher throughput. The Geekbench Vulkan result shows a similar, though less extreme, pattern: the A4500 achieves 129,980 versus 92,688 for the W7600, a 40.2% advantage. For professionals relying on OpenCL acceleration in rendering, simulation, or scientific computing, the A4500 is categorically faster.

The W7600’s wins are not found in the benchmark scores but rather in its physical and architectural attributes. It is a single-slot, 130 W card with a 300 W suggested PSU, compared to the A4500’s dual-slot, 200 W design with a 550 W suggested PSU. This makes the W7600 significantly easier to integrate into dense, multi-GPU workstations or smaller chassis where power and space are constrained. Additionally, the W7600 features DisplayPort 2.1 outputs, while the A4500 is limited to DisplayPort 1.4a. For driving the latest high-refresh-rate or high-resolution displays, the W7600’s newer display interface is a tangible advantage.

The W7600 also leads in raw clock speeds, with a 2440 MHz boost clock versus the A4500’s 1650 MHz. While this does not translate into benchmark wins, it suggests a more efficient architecture where higher frequencies compensate for fewer compute units. The W7600’s FP16 performance of 39.98 TFLOPS also exceeds the A4500’s 23.65 TFLOPS, a 2:1 versus 1:1 ratio, which matters for workloads that utilize half-precision arithmetic. However, for FP32, the A4500’s 23.65 TFLOPS surpasses the W7600’s 19.99 TFLOPS.

The Verdict

The data dictates a clear verdict: the NVIDIA RTX A4500 is the superior performer for raw compute and graphics workloads. Its 74% lead in OpenCL and 40.2% lead in Vulkan are overwhelming, and its 20 GB of GDDR6 memory with 640 GB/s bandwidth dwarfs the W7600’s 8 GB and 288 GB/s. Professionals working with large datasets, complex 3D scenes, or GPU-accelerated compute should choose the A4500 without hesitation. Its 93rd percentile ranking among all GPUs matches the W7600, but the average score difference of 4,563 points is meaningful in real-world applications.

The AMD Radeon PRO W7600, however, is not without merit. Its 130 W TDP and single-slot form factor make it an ideal choice for systems where power efficiency and physical space are paramount. The card’s 6 nm process node from TSMC, versus the A4500’s 8 nm Samsung node, contributes to this efficiency. For rendering workloads that fit within 8 GB of VRAM, the W7600 offers 19.99 TFLOPS of FP32 performance, which is only 15% lower than the A4500. The W7600 is also an active product with a launch MSRP of 599 USD, while the A4500 is end-of-life. For buyers seeking a new, warranty-backed card with the latest DisplayPort 2.1 connectivity, the W7600 is the more forward-looking choice.

Head-to-Head Benchmarks

The Geekbench OpenCL test is the most lopsided comparison. The RTX A4500’s score of 141,837 is 74% higher than the W7600’s 81,528. This delta is so large that it suggests the A4500’s 7,168 shading units and 224 texture mapping units are not just numerically superior but also more efficiently utilized in OpenCL. The A4500’s 224 tensor cores and 56 RT cores further enhance its compute capabilities, though these are not directly benchmarked here.

In Geekbench Vulkan, the A4500 again wins, scoring 129,980 against 92,688, a 40.2% advantage. While this is a smaller gap than OpenCL, it still represents a major performance difference. Vulkan is often used for real-time rendering and game-engine workloads, and the A4500’s lead indicates better suitability for interactive visualization tasks. The W7600’s 32 RT cores do help it compete, but they cannot overcome the A4500’s overall compute advantage.

The average benchmark scores reinforce this hierarchy. The A4500’s average of 91,671 places it 5.2% ahead of the W7600’s 87,108. Interestingly, the A4500’s closest rival in the data is the AMD Radeon Instinct MI60, which scores 92,466, a 0.9% difference. This shows that the A4500 is competitive with cards in a higher performance class. The W7600’s closest rival is the NVIDIA Quadro GP100, which scores 87,445, just 0.4% higher. This positions the W7600 as a mid-range card that trades blows with older flagship GPUs, but it cannot match the modern A4500.

Architecture Differences

The architectural divide between these cards is stark. The RTX A4500 uses NVIDIA’s Ampere architecture on a GA102 chip, manufactured on Samsung’s 8 nm process. This is a large, power-hungry design with 28,300 million transistors on a 628 mm² die. The W7600, by contrast, uses AMD’s RDNA 3.0 architecture on a Navi 33 chip, built on TSMC’s 6 nm process. It packs 13,300 million transistors into a 204 mm² die, yielding a transistor density of 65.2M per mm² versus the A4500’s 45.1M per mm².

The compute configurations are equally divergent. The A4500 features 7,168 shading units, 224 TMUs, and 96 ROPs, along with 56 RT cores and 224 tensor cores. The W7600 has 2,048 shading units, 128 TMUs, and 64 ROPs, with 32 RT cores but no tensor cores. This means the A4500 has dedicated hardware for AI and deep learning tasks via tensor cores, while the W7600 lacks this feature entirely. The A4500’s FP16 performance is 23.65 TFLOPS (1:1 ratio with FP32), while the W7600 achieves 39.98 TFLOPS (2:1 ratio), indicating the AMD card can execute half-precision operations at twice the rate.

Memory architecture also differs. The A4500 uses a 320-bit bus with 20 GB of GDDR6, while the W7600 uses a 128-bit bus with 8 GB. The A4500’s memory clock is 2000 MHz (16 Gbps effective), while the W7600 runs at 2250 MHz (18 Gbps effective). Despite the W7600’s faster memory clock, the A4500’s wider bus provides over twice the bandwidth. Both cards support PCIe 4.0, but the A4500 uses a full x16 interface while the W7600 is limited to x8. This could impact data transfer speeds in bandwidth-sensitive workloads, though the A4500’s memory advantage likely dominates.

Physical dimensions and power delivery further separate the two. The A4500 is a dual-slot card measuring 267 mm in length, powered by a single 8-pin connector. The W7600 is a single-slot card at 241 mm length, using a single 6-pin connector. The A4500’s 200 W TDP and 550 W suggested PSU make it a more demanding component, while the W7600’s 130 W TDP and 300 W PSU requirement allow for more flexible system integration. The A4500 is end-of-life, having launched in November 2021, while the W7600 is active, launching in August 2023 with a launch MSRP of 599 USD.
