Architecture Differences

The AMD Radeon PRO W7900 uses the Navi 31 chip built on RDNA 3.0 architecture, codenamed Plum Bonito. This is a 5 nm design fabricated by TSMC, packing 57,700 million transistors into a 529 mm² die. The transistor density reaches 109.1 million transistors per square millimeter. The NVIDIA TITAN X Pascal uses the GP102 chip on the older Pascal architecture, fabricated on a 16 nm process at TSMC. It contains 11,800 million transistors on a 471 mm² die, giving a transistor density of 25.1 million per square millimeter. The transistor count difference is nearly 5 times in favor of the AMD card, and the density difference reflects the generational leap in manufacturing technology.

The AMD Radeon PRO W7900 features 6,144 shading units, 384 texture mapping units, and 192 render output units. It also includes 96 ray tracing cores, a feature entirely absent from the NVIDIA TITAN X Pascal. The NVIDIA card has 3,584 shading units, 224 TMUs, and 96 ROPs. Neither card includes tensor cores in the recorded specifications.

The API support differs meaningfully. The AMD card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The DirectX feature level difference explains part of the Vulkan benchmark gap, though the raw compute differences also play a role.

The memory subsystems represent two different generations of technology. The AMD Radeon PRO W7900 uses 48 GB of GDDR6 memory on a 384 bit bus, delivering 864.0 GB/s of bandwidth. The NVIDIA TITAN X Pascal uses 12 GB of GDDR5X memory on the same 384 bit bus width, but only achieves 480.4 GB/s. The AMD card offers 4 times the capacity and nearly double the bandwidth.

Raw compute output shows the scale of the performance gap. The AMD Radeon PRO W7900 delivers 61.32 TFLOPS of FP32 performance and the same 61.32 TFLOPS of FP16 performance at a 1:1 ratio. The NVIDIA TITAN X Pascal delivers 10.97 TFLOPS of FP32 and only 171.5 GFLOPS of FP16 at a 1:64 ratio. The FP16 difference is particularly stark: the AMD card offers over 350 times the FP16 throughput of the NVIDIA card. Pixel and texture rates follow the same pattern, with the AMD card hitting 479.0 GPixel/s and 958.1 GTexel/s against 147.0 GPixel/s and 342.9 GTexel/s for the NVIDIA card.

Specification Differences

The two cards differ across nearly every major specification category. The process node jumps from 16 nm on the NVIDIA card to 5 nm on the AMD card. Transistor count rises from 11,800 million to 57,700 million. Die size actually decreases from 471 mm² to 529 mm², which is a modest increase, but the density gain from 25.1M to 109.1M transistors per square millimeter is transformative.

Clock speeds show the AMD card running higher: base clock of 1760 MHz versus 1417 MHz, boost clock of 2495 MHz versus 1531 MHz. Memory clocks differ as well, with the AMD card running at 2250 MHz (18 Gbps effective) versus 1251 MHz (10 Gbps effective) for the NVIDIA card. Memory capacity jumps from 12 GB to 48 GB, and memory type changes from GDDR5X to GDDR6, with bandwidth increasing from 480.4 GB/s to 864.0 GB/s.

Compute resources scale up substantially: shading units from 3,584 to 6,144, TMUs from 224 to 384, ROPs from 96 to 192. The AMD card adds 96 ray tracing cores where the NVIDIA card has none. Peak FP32 rises from 10.97 TFLOPS to 61.32 TFLOPS, and FP16 rises from 171.5 GFLOPS to 61.32 TFLOPS.

Power and physical specifications differ as well. The AMD card draws 295 W versus 250 W for the NVIDIA card, and requires a triple-slot cooler versus a dual-slot cooler. Power connectors change from 1x 6-pin plus 1x 8-pin on the NVIDIA card to 2x 8-pin on the AMD card. Both list a suggested power supply of 600 W. The AMD card is longer at 280 mm versus 267 mm, slightly shorter in height at 110 mm versus 112 mm, and thicker at 51 mm versus 40 mm. The bus interface moves from PCIe 3.0 x16 to PCIe 4.0 x16. Display outputs change from 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.4a on the NVIDIA card to 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1 on the AMD card. The NVIDIA card has a launch MSRP of 1,199 USD; the AMD card has a launch MSRP of 3,999 USD.

Where Each One Wins

The AMD Radeon PRO W7900 wins in every benchmark category recorded in the database. Its 26.5% OpenCL lead and 76.9% Vulkan lead make it the clear choice for general compute workloads and graphics API performance. The 48 GB memory capacity, combined with 864.0 GB/s bandwidth, positions it for large dataset workloads such as machine learning inference, scientific visualization, and high-resolution rendering where memory capacity directly limits scene complexity. The 1:1 FP16 ratio opens up workloads that benefit from reduced precision arithmetic without the massive throughput penalty seen on the NVIDIA card. The 96 ray tracing cores provide hardware acceleration for ray-traced rendering, a capability the NVIDIA TITAN X Pascal lacks entirely.

The NVIDIA TITAN X Pascal has no benchmark wins in the recorded data. Its strengths lie elsewhere: it draws 45 W less power, fits in a dual-slot form factor, and uses a single 6-pin plus 8-pin power configuration. The 12 GB of GDDR5X memory on a 384 bit bus still provides respectable bandwidth for its era, and the 10.97 TFLOPS of FP32 performance places it above many newer mid-range cards in the database, as shown by its 91st percentile ranking. The older card also supports DirectX 12 (12_1) and Vulkan 1.4, though the DirectX feature level is one step below the AMD card's 12 Ultimate (12_2) support.

The database positions these two cards in different performance tiers despite both ranking in the 90th percentile or above. The AMD Radeon PRO W7900 competes with workstation cards like the NVIDIA RTX A5500 Mobile and the AMD Radeon Pro Vega II, while the NVIDIA TITAN X Pascal sits alongside the AMD Radeon Pro Vega 64 and AMD Radeon RX 6650M. For users prioritizing compute throughput, memory capacity, and modern feature support, the AMD Radeon PRO W7900 is the superior part by every recorded metric. For users constrained by power, physical space, or legacy requirements, the NVIDIA TITAN X Pascal remains a functional if dated option, but the benchmark data does not show a single category where it outperforms its newer rival.
