AMD Radeon Pro W5500X vs NVIDIA RTX A5000 Comparison

Where Each One Wins

The NVIDIA RTX A5000 is the clear performance leader in this comparison, dominating across every benchmark category where both cards have recorded data. The A5000 holds a 78th percentile ranking among all GPUs in the database, while the AMD Radeon Pro W5500X sits at the 73rd percentile. The A5000's average benchmark score of 33,622 stands well above the W5500X's 27,973, a gap of roughly 20% in aggregate performance.

The A5000 wins in every measurable compute and graphics workload. It posts 157,905 in Geekbench OpenCL, a score that reflects strong general-purpose compute throughput. Its Geekbench Vulkan result of 137,828 further cements its position in cross-platform graphics APIs. The W5500X has no recorded OpenCL or Vulkan scores, so the A5000's advantages there are uncontested in the database.

The W5500X does have one exclusive strength: it is the only card of the two with a Geekbench Metal score, posting 27,973. This matters for macOS environments, as Metal is the primary graphics and compute API on Apple platforms. The card's generation label, "Radeon Pro Mac (Navi Series)," and its Apple MPX bus interface indicate it is designed for Mac Pro systems. In that specific ecosystem, the W5500X offers a native path with its 2x HDMI 2.0b outputs, while the A5000 relies on 4x DisplayPort 1.4a, which may require adapters for certain Apple displays.

For raw rasterization, the A5000's Passmark scores tell a decisive story. It reaches 22,541 in Passmark G3D, 1,032 in Passmark G2D, and 12,455 in Passmark GPU Compute. The legacy DirectX tests show 251 in DX9, 187 in DX11, 153 in DX10, and 87 in DX12. The W5500X has no Passmark entries, so the A5000 stands alone in those measurements.

The use-case split is therefore straightforward: the A5000 is the choice for maximum performance across Windows, Linux, and Vulkan workloads, while the W5500X is the only option here for Mac-centric workflows that depend on Metal. The data shows no scenario where the W5500X outperforms the A5000 in a shared benchmark, but its Apple MPX interface and Metal support give it a distinct platform-specific role.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between these two cards, so the comparison relies on their individual benchmark suites and aggregate scores. Even so, the performance hierarchy is unambiguous.

The A5000's Geekbench OpenCL score of 157,905 dwarfs anything the W5500X can produce in its sole Geekbench Metal test of 27,973. While OpenCL and Metal are different APIs, both measure general compute throughput, and the magnitude of the gap, roughly 5.6 times, reflects the A5000's massive compute advantage. The A5000's FP32 throughput of 27.77 TFLOPS versus the W5500X's 5.398 TFLOPS explains this disparity.

In Vulkan, the A5000 posts 137,828. The W5500X has no Vulkan score in the database, but its DirectX 12 (12_1) support and lower hardware specifications suggest it would fall far short. The A5000's 64 ray tracing cores and 256 tensor cores provide additional workload capabilities that the W5500X lacks entirely.

Passmark results further separate the cards. The A5000 achieves 22,541 in Passmark G3D, a comprehensive graphics score, and 12,455 in Passmark GPU Compute. Its legacy DirectX performance ranges from 251 in DX9 down to 87 in DX12, showing strong backward compatibility. The W5500X has no Passmark entries, so no direct comparison is possible, but its absence from those tests means the A5000 is the only card with verified performance in those specific workloads.

The nearest rivals in the database provide context for each card's standing. The A5000's closest competitor is the NVIDIA GeForce GTX 1060 5 GB with an average score of 33,694, a delta of -0.2%, meaning the A5000 trails that card by a negligible margin. The AMD Radeon RX 7700S sits at 33,849 (-0.7%), and the AMD Radeon HD 7950 at 33,951 (-1%). The A5000 is essentially tied with these cards in aggregate scoring, despite being a workstation part.

The W5500X's nearest rival is the NVIDIA GeForce GTX 980 Ti at 28,020, a delta of -0.2%. The AMD Radeon RX 7800M scores 27,883 (+0.3%), the AMD Radeon Pro Vega 20 scores 27,839 (+0.5%), and the AMD FirePro S7150 scores 28,117 (-0.5%). The W5500X sits in a tight cluster around 28,000, well below the A5000's neighborhood near 33,600.

Specification Differences

The two cards differ in nearly every major specification. The A5000 uses a GA102 chip from NVIDIA's Ampere architecture, while the W5500X uses AMD's Navi 14 from RDNA 1.0. The A5000 is built on Samsung's 8 nm process with 28,300 million transistors on a 628 mm² die. The W5500X uses TSMC's 7 nm process with 6,400 million transistors on a 158 mm² die. Transistor density is similar, 45.1M per mm² for the A5000 versus 40.5M per mm² for the W5500X.

Memory specifications diverge sharply. The A5000 offers 24 GB of GDDR6 on a 384-bit bus with 768.0 GB/s bandwidth and 16 Gbps effective memory speed. The W5500X has 8 GB of GDDR6 on a 128-bit bus with 224.0 GB/s bandwidth and 14 Gbps effective speed. The A5000's memory subsystem is categorically larger and faster.

Compute resources favor the A5000 overwhelmingly. It has 8192 shading units, 256 TMUs, 96 ROPs, 64 ray tracing cores, and 256 tensor cores. The W5500X has 1536 shading units, 96 TMUs, 32 ROPs, and no ray tracing or tensor cores. Pixel rate is 162.7 GPixel/s for the A5000 versus 56.22 GPixel/s for the W5500X. Texture rate is 433.9 GTexel/s versus 168.7 GTexel/s. FP32 performance is 27.77 TFLOPS versus 5.398 TFLOPS, and FP16 is 27.77 TFLOPS (1:1) for the A5000 versus 10.80 TFLOPS (2:1) for the W5500X.

Power and interface also differ. The A5000 has a 230 W TDP with a suggested 550 W PSU, uses a PCIe 4.0 x16 interface, and draws power from a single 8-pin connector. The W5500X has a 125 W TDP with a suggested 300 W PSU, uses an Apple MPX interface, and lists no power connector. Display outputs are 4x DisplayPort 1.4a on the A5000 versus 2x HDMI 2.0b on the W5500X.

DirectX support separates the cards as well. The A5000 supports DirectX 12 Ultimate (12_2), while the W5500X is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

The A5000 is a dual-slot card measuring 267 mm in length and 112 mm in height. The W5500X is also dual-slot, but no dimensions are recorded. The A5000's launch MSRP is not listed, while the W5500X has a launch MSRP of 599 USD.

Architecture Differences

The architectural gap between these two GPUs is fundamental. The A5000 is built on NVIDIA's Ampere architecture, a design that includes dedicated ray tracing cores and tensor cores. Ampere is a full-featured compute architecture with support for DirectX 12 Ultimate, which mandates hardware ray tracing and mesh shaders. The A5000's 64 ray tracing cores and 256 tensor cores enable workloads in ray-traced rendering and AI acceleration that the W5500X cannot handle at all.

The W5500X uses AMD's RDNA 1.0 architecture on the Navi 14 chip. RDNA 1.0 is a graphics-first design without dedicated ray tracing hardware or tensor-style matrix accelerators. Its DirectX 12 (12_1) support lacks the Ultimate feature set, meaning no DirectX Raytracing. The FP16 ratio of 2:1 indicates it processes half-precision at half the rate of FP32, whereas the A5000's 1:1 ratio means it handles FP16 at the same throughput as FP32, a significant advantage for compute tasks that use mixed precision.

The transistor budgets reflect these design priorities. The A5000's GA102 die contains 28,300 million transistors, over four times the W5500X's 6,400 million. The die size difference, 628 mm² versus 158 mm², is equally stark. The A5000 is a large, power-hungry compute monster designed for maximum throughput, while the W5500X is a compact, efficient chip tailored for Apple's Mac Pro ecosystem.

The A5000's 8 nm Samsung process is older and less dense than the W5500X's 7 nm TSMC process, yet the A5000 still achieves slightly higher transistor density at 45.1M per mm² versus 40.5M per mm². This confirms the scale of the GA102 design. The W5500X's smaller die and lower transistor count contribute to its 125 W TDP, nearly half the A5000's 230 W.

The generation labels in the database capture the positioning: the A5000 belongs to "Workstation Ampere (Ax000)" with a Quadro Turing predecessor and Workstation Ada successor, while the W5500X belongs to "Radeon Pro Mac (Navi Series)" with no predecessor or successor listed. The A5000 is a general-purpose workstation GPU with a clear lineage, while the W5500X is a platform-specific part tied to Apple's hardware.

The Verdict

The data points to a simple conclusion: the NVIDIA RTX A5000 is the superior GPU for almost every workload measurable in the database. It wins every shared benchmark category, offers dramatically more memory, higher compute throughput, and hardware features like ray tracing cores and tensor cores that the W5500X simply does not have. The A5000's 33,622 average score, 78th percentile ranking, and 20% aggregate advantage over the W5500X leave no room for doubt.

The A5000's performance profile is well-suited for professionals running demanding graphics applications on Windows or Linux systems. Its 24 GB memory capacity and 27.77 TFLOPS FP32 throughput handle large datasets and complex scenes without breaking stride. The nearest rival data shows the A5000 trading within 1% of cards like the GTX 1060 5 GB and RX 7700S, placing it in a respected tier despite being a workstation part.

The AMD Radeon Pro W5500X has one clear niche: Mac systems. Its Apple MPX interface, 2x HDMI 2.0b outputs, and Geekbench Metal score of 27,973 make it the appropriate choice for Mac Pro owners who need a native GPU without adapters. Its 125 W TDP and 300 W suggested PSU also make it a lighter power load in constrained systems.

Users who work exclusively in macOS environments and do not require ray tracing or extreme compute should consider the W5500X for its platform fit. Users who need maximum performance, ray tracing, AI acceleration, or large memory pools should choose the RTX A5000 without hesitation. The A5000's 5.6 times higher OpenCL score, 3 times memory capacity, and 3.4 times bandwidth advantage over the W5500X are decisive for any compute-heavy workflow.

The verdict is not close. The A5000 dominates on raw performance and features, while the W5500X wins only on platform compatibility for Apple hardware. For anything beyond a Mac-specific build, the A5000 is the clear recommendation from the recorded data.
