Architecture Differences

The architectural divide between these cards is substantial, starting with manufacturing process. The RTX 3090 Ti uses NVIDIA’s Ampere architecture built on an 8 nm Samsung process, with a massive 628 mm² die containing 28,300 million transistors. The Radeon PRO W7700 employs AMD’s RDNA 3.0 architecture on TSMC’s 5 nm node, packing 28,100 million transistors into a much smaller 346 mm² die. This yields a transistor density of 81.2M per mm² for AMD versus 45.1M per mm² for NVIDIA, reflecting the newer fabrication technology.

Compute resources differ sharply in configuration. The RTX 3090 Ti carries 10,752 shading units, 336 texture mapping units, and 112 ROPs, alongside 84 RT cores and 336 tensor cores. The Radeon PRO W7700 has 3,072 shading units, 192 TMUs, and 96 ROPs, with 48 RT cores and no tensor cores at all. This means NVIDIA’s card is built for both rasterization and AI-accelerated workloads, while AMD’s design focuses purely on shader and ray tracing performance without dedicated tensor hardware.

Clock speeds tell a different story. The Radeon PRO W7700 runs at a 1,900 MHz base and 2,600 MHz boost, significantly higher than the RTX 3090 Ti’s 1,560 MHz base and 1,860 MHz boost. The AMD card compensates for fewer cores with higher frequencies, while the NVIDIA card relies on sheer core count. This is reflected in the FP32 throughput: the RTX 3090 Ti delivers 40.00 TFLOPS versus 31.95 TFLOPS for the Radeon PRO W7700. However, in FP16, the AMD card outputs 63.90 TFLOPS at a 2:1 ratio, while the NVIDIA card matches its FP32 figure at 40.00 TFLOPS with a 1:1 ratio.

Memory architecture reinforces the divide. NVIDIA pairs its 24 GB GDDR6X with a 384-bit interface for 1.01 TB/s bandwidth, while AMD uses 16 GB GDDR6 on 256-bit bus for 576.0 GB/s. The Radeon PRO W7700’s pixel rate is higher at 249.6 GPixel/s versus 208.3 GPixel/s for the RTX 3090 Ti, but NVIDIA leads in texture rate at 625.0 GTexel/s versus 499.2 GTexel/s. The power envelope is where AMD makes its biggest architectural statement: 190 W TDP with a 450 W suggested PSU, compared to NVIDIA’s 450 W TDP and 850 W suggested PSU.

The Verdict

The data suggests the RTX 3090 Ti is the performance leader for compute-heavy workloads. Its wins in both Geekbench OpenCL and Vulkan by 61.2% and 66.2% respectively, combined with 24 GB of memory and 1.01 TB/s bandwidth, make it the stronger choice for tasks that demand maximum raw throughput and large memory pools. The 95th percentile standing for both cards indicates they compete in the same performance tier, but the NVIDIA card’s average benchmark score of 131,938 versus 118,976 shows a clear performance gap in its favor.

The Radeon PRO W7700 is the pragmatic choice for space- and power-constrained systems. At 241 mm long versus 336 mm, and dual-slot versus triple-slot, it fits where the RTX 3090 Ti cannot. Its 190 W TDP and 450 W suggested PSU mean existing power infrastructure may suffice without upgrades, and its 4x DisplayPort 2.1 outputs provide a more current display interface than the RTX 3090 Ti’s 3x DisplayPort 1.4a plus single HDMI 2.1. For users who need 16 GB of memory and don’t require tensor core acceleration, the AMD card offers competitive performance at roughly one third the power draw.

The launch MSRP for the RTX 3090 Ti is 1,999 USD, while the Radeon PRO W7700 launched at 999 USD. Users prioritizing absolute performance in OpenCL and Vulkan benchmarks should select the NVIDIA card. Users who value physical compatibility, power efficiency, and modern display outputs should select the AMD card. The RTX 3090 Ti is end-of-life production, while the Radeon PRO W7700 has no production status listed, indicating it remains an active product.

Head-to-Head Benchmarks

The head-to-head benchmark data contains only two tests, and the NVIDIA GeForce RTX 3090 Ti wins both outright. In Geekbench OpenCL, the RTX 3090 Ti scores 174,441 against the Radeon PRO W7700’s 108,245, producing a delta of 61.2%. This is the smaller of the two margins, but it still represents a commanding lead in a general-purpose compute workload that exercises both shader and memory subsystems. The 24 GB memory capacity and 1.01 TB/s bandwidth likely contribute to this advantage, as OpenCL workloads often scale with memory throughput.

The Geekbench Vulkan test shows an even wider gap. The RTX 3090 Ti achieves 215,633 points, while the Radeon PRO W7700 manages 129,706, a 66.2% delta. Vulkan benchmarks tend to stress driver efficiency and low-level hardware access, and the data indicates NVIDIA’s Ampere architecture handles this workload more effectively than AMD’s RDNA 3.0 implementation. The RTX 3090 Ti’s 84 RT cores and 336 tensor cores may provide additional acceleration paths that the Radeon PRO W7700 lacks, given its 48 RT cores and no tensor hardware.

The wins tally stands at 2 for the RTX 3090 Ti and 0 for the Radeon PRO W7700. Beyond the direct comparisons, the average benchmark scores reinforce this trend: 131,938 for NVIDIA versus 118,976 for AMD. In the nearest rival context, the RTX 3090 Ti sits 2.4% behind the RTX 4000 Ada Generation and A10M, and 2.6% behind the Radeon PRO W6800, while leading the NVIDIA L4 by 0.7%. The Radeon PRO W7700 leads the NVIDIA GB10 by 1.3%, the RTX 4000 SFF Ada Generation by 1.6%, the Tesla V100 SXM2 16 GB by 4%, and the RTX A5500 Mobile by 4.4%. These rival scores place both cards in similar competitive territory, but the direct head-to-head results show the RTX 3090 Ti with a decisive edge in the tested workloads.
