Architecture Differences

The two cards are built on fundamentally different architectures. The RTX 4090 D uses NVIDIA's AD102 chip based on Ada Lovelace, fabricated on a 5 nm process at TSMC. It packs 76,300 million transistors on a 609 mm² die, yielding a transistor density of 125.3M per mm². The chip includes 14,592 shading units, 456 TMUs, 176 ROPs, 114 RT cores, and 456 tensor cores. The tensor cores are a notable differentiator, as they enable AI-accelerated workloads that the W7700 cannot match — the AMD card has no tensor core equivalent listed.

The W7700 uses AMD's Navi 32 chip based on RDNA 3.0, also fabricated on a 5 nm process at TSMC, but with a smaller footprint. It contains 28,100 million transistors on a 346 mm² die, with a transistor density of 81.2M per mm². The chip has 3,072 shading units, 192 TMUs, 96 ROPs, and 48 RT cores. The FP16 performance is notable: the W7700 delivers 63.90 TFLOPS at a 2:1 ratio, compared to the RTX 4090 D's 73.54 TFLOPS at a 1:1 ratio. This means the AMD card can double its FP16 throughput, while the NVIDIA card maintains equal FP16 and FP32 rates.

The RTX 4090 D also features a larger memory subsystem with GDDR6X, while the W7700 uses GDDR6. The NVIDIA card's memory clock is 1313 MHz with 21 Gbps effective speed; the AMD card's memory clock is 2250 MHz with 18 Gbps effective speed. Despite the higher memory clock on the AMD side, the NVIDIA card's wider 384-bit bus gives it far superior bandwidth.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The fundamental architectural differences — tensor cores, shading unit count, and memory design — drive the massive performance gap.

Specification Differences

The two cards differ in nearly every measurable specification. The RTX 4090 D has a base clock of 2280 MHz and a boost clock of 2520 MHz, while the W7700 has a base clock of 1900 MHz and a boost clock of 2600 MHz. The AMD card actually has a higher boost clock, but the NVIDIA card compensates with far more compute units.

Memory is a major differentiator: 24 GB GDDR6X on a 384-bit bus with 1.01 TB/s bandwidth versus 16 GB GDDR6 on a 256-bit bus with 576.0 GB/s bandwidth. The RTX 4090 D has 14,592 shading units, 456 TMUs, 176 ROPs, and 114 RT cores. The W7700 has 3,072 shading units, 192 TMUs, 96 ROPs, and 48 RT cores. The NVIDIA card has 4.75 times more shading units and 2.375 times more RT cores.

Compute throughput tells a similar story: the RTX 4090 D delivers 73.54 TFLOPS FP32 and 73.54 TFLOPS FP16 (1:1). The W7700 delivers 31.95 TFLOPS FP32 and 63.90 TFLOPS FP16 (2:1). Pixel and texture rates also favor NVIDIA: 443.5 GPixel/s and 1,149.1 GTexel/s versus 249.6 GPixel/s and 499.2 GTexel/s.

Power and physical design are where the W7700 wins. The RTX 4090 D draws 425 W, requires a 1x 16-pin connector, and an 800 W suggested PSU. The W7700 draws 190 W, uses a 1x 8-pin connector, and needs only a 450 W PSU. The RTX 4090 D is triple-slot, 304 mm long, 137 mm high, and 61 mm wide. The W7700 is dual-slot, 241 mm long, and 111 mm high. Display outputs also differ: 1x HDMI 2.1 and 3x DisplayPort 1.4a on NVIDIA versus 4x DisplayPort 2.1 on AMD. The RTX 4090 D is marked end-of-life, while the W7700's production status is not listed. The RTX 4090 D has a launch MSRP of 1,599 USD; the W7700's launch MSRP is 999 USD.

Head-to-Head Benchmarks

The available head-to-head data is limited to two Geekbench tests, and the RTX 4090 D wins both decisively. In Geekbench OpenCL, the RTX 4090 D scores 278,621 against the W7700's 108,245, a delta of 157.4%. This is the single largest performance gap in the comparison, reflecting the NVIDIA card's massive advantage in shading units and memory bandwidth. OpenCL workloads often scale with raw compute throughput, and the RTX 4090 D's 73.54 TFLOPS FP32 versus 31.95 TFLOPS on the W7700 explains the result.

In Geekbench Vulkan, the RTX 4090 D scores 246,941 versus 129,706, a 90.4% lead. The gap narrows compared to OpenCL, but the NVIDIA card still nearly doubles the AMD card's score. Vulkan performance can be more sensitive to driver optimization and memory latency, but the RTX 4090 D's superior hardware resources carry it through.

The RTX 4090 D wins 2 of 2 head-to-head tests, with 0 wins for the W7700. The average benchmark score trend reinforces this: 178,050 for the RTX 4090 D versus 118,976 for the W7700. The nearest rival data puts these results in context. The RTX 4090 D's closest competitors are all high-end NVIDIA parts, with the RTX PRO 5000 Blackwell 2.2% faster, the A100 SXM4 80 GB 3.1% faster, the RTX 5000 Ada Generation 3.6% faster, and the A100 SXM4 40 GB 4.9% faster. The W7700's nearest rivals include the NVIDIA GB10 (1.3% slower), RTX 4000 SFF Ada Generation (1.6% slower), Tesla V100 SXM2 16 GB (4% slower), and RTX A5500 Mobile (4.4% slower). This shows the W7700 is competitive with mid-range NVIDIA workstation cards, but the RTX 4090 D operates in a completely different performance tier — one populated by datacenter-grade accelerators.

For users deciding between these two, the benchmark data is unambiguous: the RTX 4090 D is the performance king by a wide margin. The W7700's appeal lies not in speed but in efficiency, size, and display connectivity. Choose accordingly.
