AMD Radeon PRO W7800 vs NVIDIA GeForce RTX 4090 D Comparison

# NVIDIA GeForce RTX 4090 D vs AMD Radeon PRO W7800

The NVIDIA GeForce RTX 4090 D and AMD Radeon PRO W7800 occupy adjacent percentile ranks but differ sharply in architecture and workload orientation. The RTX 4090 D holds the 98th percentile among all GPUs with an average benchmark score of 178,050, while the Radeon PRO W7800 sits at the 97th percentile with an average score of 164,894 — a 7.9% gap between the two. In head-to-head testing, the RTX 4090 D wins both available benchmarks, taking Geekbench OpenCL by 80.5% and Geekbench Vulkan by 40.8%. The verdict leans on these margins, but the Radeon PRO W7800 counters with double the VRAM, a lower power draw, and a significantly higher launch MSRP — details that matter for specific professional use cases.

The Verdict

The data points to a clear split: the NVIDIA GeForce RTX 4090 D is the performance leader in every measured benchmark, while the AMD Radeon PRO W7800 offers a different set of trade-offs that may suit memory-hungry or power-constrained environments. The RTX 4090 D wins both head-to-head tests — Geekbench OpenCL at 278,621 versus 154,366 (an 80.5% advantage) and Geekbench Vulkan at 246,941 versus 175,422 (a 40.8% advantage). Its average benchmark score of 178,050 places it 7.9% above the W7800's 164,894, and it ranks in the 98th percentile versus the W7800's 97th. For users prioritizing raw compute and rendering throughput, the RTX 4090 D is the unambiguous choice from this dataset.

However, the Radeon PRO W7800 is not without rationale. It carries 32 GB of GDDR6 memory versus 24 GB of GDDR6X on the RTX 4090 D — a 33% capacity advantage that could matter for large datasets or models exceeding 24 GB. Its 260 W TDP is 165 W lower than the RTX 4090 D's 425 W, and it requires a 600 W suggested PSU versus 800 W. It also uses dual-slot cooling and two 8-pin connectors, whereas the RTX 4090 D needs triple-slot space and a single 16-pin connector. The W7800 is an active product with a 2,499 USD launch MSRP, while the RTX 4090 D is end-of-life with a 1,599 USD launch MSRP — the data shows the NVIDIA card is cheaper at launch despite being discontinued. Users who need maximum memory capacity, lower system power draw, or a compact dual-slot form factor should favor the W7800; those who need peak compute performance should choose the RTX 4090 D.

Architecture Differences

The two GPUs stem from different design philosophies. The RTX 4090 D uses NVIDIA's AD102 chip on the Ada Lovelace architecture, manufactured on a 5 nm process at TSMC, with 76,300 million transistors across a 609 mm² die — a transistor density of 125.3 million per mm². The Radeon PRO W7800 uses AMD's Navi 31 chip on RDNA 3.0 (codename Plum Bonito), also fabricated on TSMC's 5 nm node, but with 57,700 million transistors on a smaller 529 mm² die, yielding a lower density of 109.1 million per mm². The RTX 4090 D packs more hardware: 14,592 shading units, 456 TMUs, 176 ROPs, 114 RT cores, and 456 tensor cores. The W7800 counters with 4,480 shading units, 280 TMUs, 128 ROPs, and 70 RT cores, with no tensor core count listed.

Clock behavior differs subtly. The RTX 4090 D has a base clock of 2280 MHz and a boost of 2520 MHz; the W7800 starts at 1895 MHz base but boosts to 2525 MHz — a 5 MHz higher peak. Memory configurations diverge more significantly. The RTX 4090 D uses 24 GB of GDDR6X on a 384-bit bus, delivering 1.01 TB/s of bandwidth with memory clocks at 1313 MHz (21 Gbps effective). The W7800 uses 32 GB of GDDR6 on a narrower 256-bit bus, achieving 576.0 GB/s at 2250 MHz (18 Gbps effective) — a 43% bandwidth deficit but a 33% capacity surplus.

Compute throughput favors the RTX 4090 D in FP32: 73.54 TFLOPS versus 45.25 TFLOPS. In FP16, the W7800 reaches 90.50 TFLOPS (2:1 rate) versus the RTX 4090 D's 73.54 TFLOPS (1:1 rate), meaning the AMD card actually exceeds the NVIDIA card in peak half-precision throughput. Pixel and texture rates also differ: the RTX 4090 D posts 443.5 GPixel/s and 1,149.1 GTexel/s, while the W7800 manages 323.2 GPixel/s and 707.0 GTexel/s. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and both use PCIe 4.0 x16. Display outputs differ: the RTX 4090 D offers 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the W7800 provides 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1 — a generational advantage for the AMD card in display connectivity.

Head-to-Head Benchmarks

The RTX 4090 D dominates both recorded head-to-head tests. In Geekbench OpenCL, it scores 278,621 against the W7800's 154,366, a delta of 80.5%. That margin is enormous — the NVIDIA card nearly doubles the AMD card's score. The gap suggests the RTX 4090 D's higher shading unit count (14,592 versus 4,480) and FP32 throughput (73.54 TFLOPS versus 45.25 TFLOPS) translate directly into OpenCL compute performance. For context, the RTX 4090 D's nearest rivals in average score are the NVIDIA RTX PRO 5000 Blackwell (182,109, -2.2%), NVIDIA A100 SXM4 80 GB (183,725, -3.1%), and NVIDIA RTX 5000 Ada Generation (184,664, -3.6%) — all within 5% of the RTX 4090 D. The W7800's nearest rivals include the NVIDIA RTX A5500 (165,217, -0.2%), RTX 4500 Ada Generation (166,094, -0.7%), and AMD Radeon Pro W6900X (168,574, -2.2%), showing it sits in a tighter, lower-performance cluster.

In Geekbench Vulkan, the RTX 4090 D scores 246,941 versus 175,422 for the W7800, a 40.8% delta. This smaller margin still represents a decisive win. Vulkan exercises graphics and compute paths differently than OpenCL, and the RTX 4090 D's 114 RT cores and 456 tensor cores may contribute to its advantage, though the W7800's 70 RT cores also handle ray tracing workloads. The RTX 4090 D also holds a 3dmark_3dmark_steel_nomad_dx12 score of 8,587, a test not run on the W7800 in this dataset, further indicating its DirectX 12 strength. Across both shared benchmarks, the RTX 4090 D wins 2 out of 2, with no wins for the W7800.

Where Each One Wins

The RTX 4090 D wins in raw compute performance across all shared benchmarks. Its OpenCL score of 278,621 is 80.5% ahead, and its Vulkan score of 246,941 is 40.8% ahead. It also leads in pixel rate (443.5 GPixel/s versus 323.2 GPixel/s), texture rate (1,149.1 GTexel/s versus 707.0 GTexel/s), and FP32 throughput (73.54 TFLOPS versus 45.25 TFLOPS). Its 1.01 TB/s memory bandwidth dwarfs the W7800's 576.0 GB/s, and its 384-bit bus supports that throughput. For workloads like 3D rendering, simulation, or high-FP32 compute, the RTX 4090 D is the stronger pick. It also holds the 3dmark_3dmark_steel_nomad_dx12 score of 8,587, which the W7800 does not contest in this dataset. Its launch MSRP of 1,599 USD is also 900 USD lower than the W7800's 2,499 USD, though the card is end-of-life.

The W7800 wins where capacity and efficiency matter. Its 32 GB of GDDR6 memory exceeds the RTX 4090 D's 24 GB, accommodating larger working sets. Its 260 W TDP draws 165 W less power, reducing system-level requirements and heat output. Its dual-slot design and 2x 8-pin connectors make it easier to fit in dense workstations, and its 4 DisplayPort 2.1 outputs (including one mini-DisplayPort) surpass the RTX 4090 D's HDMI 2.1 and DisplayPort 1.4a configuration. In FP16, the W7800's 90.50 TFLOPS beats the RTX 4090 D's 73.54 TFLOPS, making it competitive for half-precision AI or compute tasks. Its 97th percentile rank places it just one percentile below the RTX 4090 D, with an average score only 7.9% lower — a modest gap for a card with 33% more VRAM and 39% lower TDP. Users prioritizing memory capacity, power efficiency, or display connectivity should choose the W7800; those needing maximum compute throughput should choose the RTX 4090 D.
