AMD Radeon Pro W6600M vs NVIDIA GeForce RTX 5090 D Comparison

Head-to-Head Benchmarks

The recorded data shows a dominant performance gap in the two shared benchmark tests, both of which are won decisively by the NVIDIA GeForce RTX 5090 D. In Geekbench OpenCL, the RTX 5090 D scores 310,674 points against 56,140 for the AMD Radeon Pro W6600M, which translates to a 453.4% advantage. The Vulkan test tells a similar story: the NVIDIA card posts 376,915 points versus 67,652, a 457.1% lead. These are not marginal differences; the NVIDIA GPU is roughly five and a half times faster in both compute workloads based on the delta percentages.

Context from the database’s nearest rival comparisons reinforces how unusual this spread is. The RTX 5090 D sits at the 92nd percentile among all GPUs, with an average benchmark score of 77,712. Its closest competitors in the database, such as the AMD Radeon RX 6850M XT and NVIDIA Tesla P100 variants, are within 1.6% to 2.4% of its average score, meaning the RTX 5090 D is at the very top of a tightly clustered group of high-end parts. Meanwhile, the Radeon Pro W6600M holds the 89th percentile, but its average score of 61,896 places it in a different league entirely. Interestingly, its nearest rivals include the NVIDIA GeForce RTX 4090, which trails by 2.6% in average score, and the Intel Arc Pro A60, also 2.6% behind. The W6600M actually leads those parts slightly, but that does little to close the chasm with the RTX 5090 D.

Looking at the individual test results for the RTX 5090 D, the pattern holds across legacy and modern workloads. In Passmark DirectX 9, it scores 434, while DirectX 11 yields 371, DirectX 10 scores 231, and DirectX 12 drops to 219. The Passmark G3D score is 44,065, with a GPU compute score of 28,396 and a G2D score of 1,487. The 3DMark Steel Nomad DX12 test produces 14,326 points. For the W6600M, only two benchmark entries exist in the database: the Geekbench OpenCL and Vulkan scores already cited. No DirectX or 3DMark figures are recorded for the AMD part, so the head-to-head comparison is limited to those two compute-oriented tests. Still, the data is unambiguous: the RTX 5090 D wins both, and wins by a margin that is unprecedented in typical rival comparisons.

The Verdict

The database clearly separates these two GPUs into different performance tiers, and the choice depends entirely on workload requirements. For any task that demands raw compute throughput, the NVIDIA GeForce RTX 5090 D is the only rational pick. Its 453.4% lead in OpenCL and 457.1% lead in Vulkan leave no room for debate. The RTX 5090 D also carries 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth, which is essential for large datasets and high-resolution textures. The AMD Radeon Pro W6600M, with 8 GB of GDDR6 on a 128-bit bus and 224.0 GB/s bandwidth, is a capable mobile workstation part, but it is not in the same class.

However, the data does not support a blanket dismissal of the W6600M. Its 90 W TDP and IGP slot width make it a low-power, integrated solution for thin laptops, whereas the RTX 5090 D demands 575 W and a dual-slot cooler with a 16-pin power connector. The NVIDIA card is also physically large: 304 mm long, 137 mm high, and 48 mm wide. The W6600M has no listed dimensions, which reflects its mobile, solder-down nature. So the verdict is contextual: the RTX 5090 D is for desktop workstations and high-end laptops where performance is paramount, while the W6600M serves portable, power-constrained systems that prioritize battery life and thermal envelopes over compute muscle.

The production status reinforces this split. The RTX 5090 D is listed as Active, released on January 29, 2025, while the W6600M is End-of-life, released on June 7, 2021. For new purchases, the NVIDIA part is the current-generation choice. The W6600M’s predecessor was FirePro Mobile, and it has no successor listed, suggesting AMD has moved on. The RTX 5090 D’s predecessor is the GeForce 40 series, with a GeForce 60 series successor already noted in the database. In short, the data points to the RTX 5090 D for anyone who needs maximum compute, and the W6600M only for legacy mobile deployments where its low power profile is non-negotiable.

Architecture Differences

The two GPUs are built on fundamentally different architectures and process nodes. The NVIDIA GeForce RTX 5090 D uses the GB202 chip based on Blackwell 2.0 architecture, fabricated by TSMC on a 5 nm process. It integrates 92,200 million transistors on a 750 mm² die, yielding a transistor density of 122.9 million per mm². The AMD Radeon Pro W6600M uses the Navi 23 chip based on RDNA 2.0 architecture, also from TSMC but on a 7 nm process. It packs 11,060 million transistors on a 237 mm² die, with a density of 46.7 million per mm². The density difference is stark: the NVIDIA chip packs nearly three times as many transistors per area, which correlates with its massive compute advantage.

Core counts diverge sharply. The RTX 5090 D has 21,760 shading units, 680 texture mapping units, and 176 ROPs. It also features 170 RT cores and 680 tensor cores, the latter being absent from the W6600M entirely. The AMD part has 1,792 shading units, 112 TMUs, and 64 ROPs, plus 28 RT cores. The NVIDIA GPU’s FP32 throughput is 104.8 TFLOPS, while the W6600M delivers 7.290 TFLOPS. Interestingly, the RTX 5090 D achieves the same 104.8 TFLOPS for FP16, indicating a 1:1 ratio, whereas the W6600M doubles its FP32 rate to 14.58 TFLOPS at a 2:1 ratio. This means the AMD card is relatively stronger in half-precision workloads, but its absolute numbers still fall far short.

Memory subsystems are equally divergent. The RTX 5090 D runs 32 GB of GDDR7 at 1750 MHz, with an effective data rate of 28 Gbps, across a 512-bit bus for 1.79 TB/s bandwidth. The W6600M uses 8 GB of GDDR6 at 1750 MHz, 14 Gbps effective, on a 128-bit bus, yielding 224.0 GB/s. That is a 8x difference in bus width and a 7.9x difference in bandwidth, which explains why the NVIDIA card can feed its 423.6 GPixel/s pixel rate and 1,636.8 GTexel/s texture rate. The W6600M’s pixel rate is 130.2 GPixel/s and texture rate is 227.8 GTexel/s. Clock speeds also differ: the RTX 5090 D boosts to 2407 MHz from a 2017 MHz base, while the W6600M boosts to 2034 MHz from a 1224 MHz base.

Connectivity and power profiles are opposite in intent. The RTX 5090 D uses PCIe 5.0 x16, has a dual-slot design, a single 16-pin connector, and a suggested PSU of 950 W. Its display outputs are 1x HDMI 2.1b and 3x DisplayPort 2.1b. The W6600M uses PCIe 4.0 x16, is an IGP (integrated graphics processor) with no power connectors, and its display outputs are listed as portable device dependent. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The RTX 5090 D’s 575 W TDP is a clear trade-off for its performance, while the W6600M’s 90 W TDP makes it suitable for systems where power draw is a hard constraint.

Where Each One Wins

The RTX 5090 D wins every benchmark where both GPUs have recorded data, but its advantages extend beyond raw scores. For compute-heavy tasks such as machine learning inference, scientific simulation, or large-scale rendering, the 104.8 TFLOPS FP32 throughput and 680 tensor cores make it the obvious choice. The 32 GB VRAM capacity is another decisive factor: it can hold models and datasets that would exceed the W6600M’s 8 GB limit by a wide margin. The 1.79 TB/s bandwidth ensures that memory-bound workloads are not starved for data. In multi-GPU or high-end desktop configurations, the PCIe 5.0 x16 interface and dual-slot cooler with a 16-pin connector are designed for sustained throughput.

The W6600M wins in scenarios where power and physical footprint are the primary constraints. Its 90 W TDP is less than one-sixth of the RTX 5090 D’s 575 W, and its IGP form factor means it can be integrated directly into a motherboard without discrete cooling or power delivery. That makes it viable for compact, battery-powered mobile workstations where the RTX 5090 D simply cannot fit. The 7 nm process, while older, allows for a 237 mm² die that is easy to integrate. For legacy applications that only require moderate compute, such as CAD or light video editing, the W6600M’s 7.290 TFLOPS may be sufficient, and its 14.58 TFLOPS FP16 performance shows it has some headroom for half-precision tasks.

The database also shows the W6600M holds its own against its direct peers: it leads the NVIDIA GeForce RTX 4090 by 2.6% in average score, which is remarkable for a mobile part. But that comparison is irrelevant when stacked against the RTX 5090 D, which outscores it by over 400% in both OpenCL and Vulkan. For users who need the absolute best compute performance available in the database, the RTX 5090 D is the definitive winner. For users who need a low-power, integrated GPU for portable workstations, the W6600M remains a viable, if dated, option. The data does not support any scenario where the W6600M outperforms the RTX 5090 D in raw speed, but it does carve out a niche in efficiency and form factor.
