AMD Radeon PRO W6600 vs NVIDIA GeForce RTX 5080 Comparison

Head-to-Head Benchmarks

The recorded data contains two direct head-to-head comparisons between the AMD Radeon PRO W6600 and the NVIDIA GeForce RTX 5080, and both tell a consistent story of NVIDIA dominance. In the Geekbench OpenCL test, the RTX 5080 scores 235,901 against the W6600's 73,514, a delta of -68.8% for the AMD card. That is not a marginal gap; it is a fundamental difference in compute throughput. The Geekbench Vulkan result follows the same pattern, with the RTX 5080 posting 255,450 versus 78,428, a -69.3% delta. The W6600 wins zero head-to-head tests, while the RTX 5080 wins both.

The OpenCL score gap deserves closer inspection. The W6600's 73,514 is closer to its own nearest rivals than it is to the RTX 5080. For context, the W6600's average benchmark score sits at 81,995, which places it in the 92nd percentile of all GPUs. The RTX 5080, despite its much higher raw scores in these two tests, has an average benchmark score of 56,083 and sits in the 87th percentile. This inversion is curious: the RTX 5080 crushes the W6600 in the head-to-head tests but has a lower average score overall. The explanation lies in the benchmark mix: the RTX 5080's average includes several Passmark tests with low scores (e.g., 208 in DirectX 10, 151 in DirectX 12, 389 in DirectX 9), which drag down its mean. The W6600 only has three Geekbench scores recorded, all relatively high.

The Vulkan delta of -69.3% is the largest in the dataset. The W6600's 78,428 is respectable on its own, but the RTX 5080's 255,450 is in a different class. The RTX 5080 also shows strong performance in its other recorded tests: 36,565 in Passmark G3D and 21,789 in Passmark GPU Compute. The W6600 has no Passmark entries, so the database cannot compare those workloads directly. What the data does show is that in the two shared tests, the RTX 5080 is roughly 3.2 to 3.3 times faster, depending on the test.

A: The AMD Radeon PRO W6600 is listed as end-of-life, with a release date of June 7, 2021. The NVIDIA GeForce RTX 5080 is listed as active, with a release date of January 29, 2025, and a successor already named (GeForce 60).

Architecture Differences

The two GPUs come from entirely different architectural generations and design philosophies. The AMD Radeon PRO W6600 uses the Navi 23 chip built on RDNA 2.0 architecture, fabricated on a 7 nm process at TSMC. The NVIDIA GeForce RTX 5080 uses the GB203 chip built on Blackwell 2.0 architecture, fabricated on a 5 nm process, also at TSMC. The process node difference alone is significant: 7 nm versus 5 nm means the RTX 5080 packs transistors more densely. The numbers confirm this: the W6600 has 11,060 million transistors on a 237 mm² die, giving a density of 46.7 million per mm². The RTX 5080 has 45,600 million transistors on a 378 mm² die, yielding 120.6 million per mm². That is roughly 2.6 times the transistor density.

The compute resources differ dramatically. The W6600 has 1,792 shading units, 112 texture mapping units, and 64 ROPs. The RTX 5080 has 10,752 shading units, 336 TMUs, and 112 ROPs. The RTX 5080 also has 84 ray tracing cores and 336 tensor cores, while the W6600 has 28 ray tracing cores and no tensor cores. The tensor core absence is notable: it means the W6600 cannot accelerate AI workloads the way the RTX 5080 can. The FP32 compute figures reflect this: the W6600 delivers 9.247 TFLOPS, while the RTX 5080 delivers 56.28 TFLOPS. For FP16, the W6600 achieves 18.49 TFLOPS with a 2:1 ratio, while the RTX 5080 achieves 56.28 TFLOPS with a 1:1 ratio.

The memory architectures are also fundamentally different. The W6600 uses 8 GB of GDDR6 on a 128-bit bus, providing 224.0 GB/s of bandwidth. The RTX 5080 uses 16 GB of GDDR7 on a 256-bit bus, providing 960.0 GB/s. Both support the same DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 APIs, so software compatibility is not a differentiator. The bus interface does differ: the W6600 uses PCIe 4.0 x8, while the RTX 5080 uses PCIe 5.0 x16, which affects data transfer rates to and from the host system.

Specification Differences

The following fields differ between the two GPUs in the database: process node (7 nm for AMD, 5 nm for NVIDIA), transistor count (11,060 million versus 45,600 million), die size (237 mm² versus 378 mm²), transistor density (46.7M/mm² versus 120.6M/mm²), base clock (2331 MHz versus 2295 MHz), boost clock (2580 MHz versus 2617 MHz), memory clock (1750 MHz with 14 Gbps effective versus 1875 MHz with 30 Gbps effective), memory size (8 GB versus 16 GB), memory type (GDDR6 versus GDDR7), memory bus width (128 bit versus 256 bit), bandwidth (224.0 GB/s versus 960.0 GB/s), shading units (1792 versus 10752), TMUs (112 versus 336), ROPs (64 versus 112), RT cores (28 versus 84), tensor cores (none versus 336), pixel rate (165.1 GPixel/s versus 293.1 GPixel/s), texture rate (289.0 GTexel/s versus 879.3 GTexel/s), FP32 (9.247 TFLOPS versus 56.28 TFLOPS), FP16 (18.49 TFLOPS versus 56.28 TFLOPS), TDP (100 W versus 360 W), slot width (single-slot versus dual-slot), power connectors (1x 6-pin versus 1x 16-pin), suggested PSU (300 W versus 750 W), bus interface (PCIe 4.0 x8 versus PCIe 5.0 x16), display outputs (4x DisplayPort 1.4a versus 1x HDMI 2.1b and 3x DisplayPort 2.1b), dimensions (241 mm length versus 304 mm length, 137 mm height, 40 mm width), production status (end-of-life versus active), release date (June 7, 2021 versus January 29, 2025), predecessor (Radeon Pro Vega versus GeForce 40), successor (none versus GeForce 60), and launch MSRP (649 USD versus 999 USD).

Where Each One Wins

Based strictly on the recorded data, the NVIDIA GeForce RTX 5080 wins the head-to-head compute benchmarks outright. It outperforms the W6600 in OpenCL by 68.8% and in Vulkan by 69.3%. The RTX 5080 also shows strength in its broader benchmark suite: its Passmark G3D score of 36,565 and GPU compute score of 21,789 indicate strong general-purpose rendering and compute capabilities. Its 16 GB of GDDR7 memory with 960.0 GB/s bandwidth makes it suitable for memory-intensive workloads, and its 336 tensor cores enable AI acceleration that the W6600 cannot offer.

The AMD Radeon PRO W6600 wins in efficiency and form factor. Its TDP of 100 W is less than a third of the RTX 5080's 360 W, and it requires only a 300 W suggested PSU versus 750 W for the RTX 5080. It is a single-slot card at 241 mm length, compared to the RTX 5080's dual-slot 304 mm design. For multi-GPU workstations or systems with tight power budgets, the W6600 is the more practical choice. Its 4x DisplayPort 1.4a outputs also allow for multi-monitor setups without relying on HDMI.

The percentile data adds nuance. The W6600 sits in the 92nd percentile of all GPUs, while the RTX 5080 sits in the 87th percentile. This suggests that in the broader context of all recorded GPUs, the W6600 holds its own relative to the entire field, even though it loses decisively to the RTX 5080 in direct comparison. The W6600's average score of 81,995 is higher than the RTX 5080's 56,083, but this is skewed by the different benchmark sets each GPU was tested with.

The Verdict

The data supports a clear split based on workload and system constraints. If compute performance is the priority, the NVIDIA GeForce RTX 5080 is the unambiguous choice. It delivers 3.2 to 3.3 times the performance in the shared OpenCL and Vulkan tests, offers double the memory (16 GB versus 8 GB), and provides tensor cores for AI workloads. Its 56.28 TFLOPS FP32 and FP16 performance dwarfs the W6600's 9.247 TFLOPS. The RTX 5080 is also the only one of the two with an active production status and a successor planned, suggesting ongoing driver support and a future upgrade path.

If power efficiency, physical footprint, or system integration is the constraint, the AMD Radeon PRO W6600 is the better fit. It consumes 100 W versus 360 W, fits in a single slot, and requires a 300 W PSU. Its 92nd percentile ranking shows it is a strong performer relative to the entire GPU database, and its 8 GB of GDDR6 memory is sufficient for many professional workloads. The W6600 is end-of-life, so it is a legacy option, but for existing systems or those with strict power limits, it remains viable.

The choice ultimately depends on whether the user prioritizes raw compute or system efficiency. The RTX 5080 wins every direct benchmark, but the W6600 wins on power, size, and overall percentile standing. Neither card is objectively better across all metrics; the data simply shows two different design philosophies serving different priorities.
