Direct benchmark comparisons show a split decision, with each card claiming a decisive victory in different API environments, making the choice dependent on the software ecosystem you plan to use.

Head-to-Head Benchmarks

The two cards split their direct benchmark confrontations exactly one win apiece, with the decisive factor being the graphics API used. In the Geekbench OpenCL test, the AMD Radeon Pro WX 8200 takes the lead with a score of 69,774, beating the NVIDIA TITAN X Pascal’s 66,696 by a margin of 4.4%. This is a significant gap in a compute-heavy workload, suggesting AMD’s GCN architecture handles raw OpenCL parallel processing more efficiently when both cards are pushed to their limits.

However, the NVIDIA TITAN X Pascal strikes back emphatically in the Geekbench Vulkan test, posting 77,499 against the Radeon Pro WX 8200’s 69,076. That represents a commanding 12.2% advantage for NVIDIA, a much larger swing than AMD’s OpenCL win. This result indicates that NVIDIA’s Pascal architecture is substantially better optimized for Vulkan’s lower-level, driver-controlled approach, which can translate to real-world gains in modern game engines and Vulkan-based rendering applications.

Looking at the broader benchmark averages, the AMD card holds a slight edge in aggregate performance. The Radeon Pro WX 8200 averages 69,870 across its benchmark suite, while the TITAN X Pascal averages 72,098 across its own. This puts the TITAN X Pascal in the 91st percentile of all GPUs, while the Radeon Pro WX 8200 sits in the 90th percentile. The difference is small, but it is worth remembering the TITAN X Pascal’s average is boosted by its strong Vulkan showing, while the AMD card’s average includes a Metal score of 70,759, which is the only Metal benchmark in the pack.

When comparing to their nearest rivals, the TITAN X Pascal sits just 0.4% behind the AMD Radeon Pro Vega 64 in average score, and 1.7% behind the AMD Radeon Vega Frontier Edition. It is also 0.5% ahead of the AMD Radeon RX 6650M and 1.8% ahead of the AMD Radeon RX 6600 LE. The Radeon Pro WX 8200, meanwhile, is virtually tied with the NVIDIA Quadro P6000, trailing by only 0.2%, and sits 1.3% ahead of the NVIDIA CMP 90HX. It is 0.4% behind the NVIDIA RTX A3000 Mobile and 1.4% behind the AMD Radeon RX 6600 LE. These narrow deltas show both cards are competitively positioned in their respective performance tiers, with no clear overall winner outside of specific API workloads.

Where Each One Wins

The AMD Radeon Pro WX 8200 is the clear choice for OpenCL-centric applications. Its 4.4% advantage in that benchmark indicates a hardware-level efficiency for OpenCL compute tasks, which are common in scientific simulation, machine learning inference, and some rendering pipelines. The card’s higher raw FP16 throughput of 21.50 TFLOPS, compared to the TITAN X Pascal’s 171.5 GFLOPS (1:64), suggests it can handle half-precision workloads at a far superior rate, which is increasingly relevant for AI and neural network tasks where FP16 is used to accelerate training and inference. This is a massive theoretical advantage, over 100 times in raw FP16 compute, though real-world gains depend on software support.

The NVIDIA TITAN X Pascal wins decisively in Vulkan, where its 12.2% lead over the AMD card is substantial. This suggests superior driver maturity and architectural efficiency for Vulkan’s explicit multi-threading model, which can significantly boost performance in games and real-time 3D applications built on Vulkan. For users running DXVK or native Vulkan titles, the TITAN X Pascal is the faster card. Additionally, the TITAN X Pascal’s 12 GB of GDDR5X memory, while slower in bandwidth than the AMD card’s HBM2, provides 50% more capacity, which is a practical advantage for large texture sets, complex 3D scenes, or datasets that exceed 8 GB.

The AMD card’s HBM2 memory offers 512.0 GB/s of bandwidth, which is 6.6% higher than the TITAN X Pascal’s 480.4 GB/s. This bandwidth advantage helps in memory-intensive compute workloads where data throughput is the bottleneck. The Radeon Pro WX 8200 also has a lower TDP of 230 W versus 250 W, making it slightly more power-efficient in absolute terms, and it requires a smaller 550 W power supply recommendation versus 600 W.

Specification Differences

The two cards diverge significantly in memory, but share identical core computing resources. Both the NVIDIA TITAN X Pascal and the AMD Radeon Pro WX 8200 feature 3,584 shading units and 224 texture mapping units. However, the TITAN X Pascal has 96 ROPs, while the Radeon Pro WX 8200 has only 64, a 50% difference that affects pixel fill rate. The TITAN X Pascal’s pixel rate is 147.0 GPixel/s versus 96.00 GPixel/s for the AMD card. The texture rates are closer, with 342.9 GTexel/s for NVIDIA and 336.0 GTexel/s for AMD.

Memory is a major differentiator. The TITAN X Pascal uses 12 GB of GDDR5X on a 384-bit bus, achieving 480.4 GB/s bandwidth. The Radeon Pro WX 8200 uses 8 GB of HBM2 on a 2048-bit bus, achieving 512.0 GB/s. The AMD card’s memory clock is listed as 1000 MHz with 2 Gbps effective, while the NVIDIA card runs at 1251 MHz with 10 Gbps effective, but the much wider bus gives the AMD card the bandwidth advantage.

Clock speeds also differ. The TITAN X Pascal has a base clock of 1417 MHz and a boost clock of 1531 MHz, while the Radeon Pro WX 8200 has a base of 1200 MHz and a boost of 1500 MHz. This means the NVIDIA card has a 12.1% higher base clock and a 2.1% higher boost clock. The FP32 performance is nearly identical, with the TITAN X Pascal at 10.97 TFLOPS and the Radeon Pro WX 8200 at 10.75 TFLOPS.

Power consumption and physical dimensions are similar. The TITAN X Pascal has a TDP of 250 W, while the Radeon Pro WX 8200 has a TDP of 230 W. Both require a dual-slot cooler and a 1x 6-pin + 1x 8-pin power connector configuration. The suggested PSU is 600 W for NVIDIA and 550 W for AMD. Both cards are 267 mm long and approximately 112 mm tall. Display outputs differ: the TITAN X Pascal offers 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.4a, while the Radeon Pro WX 8200 offers only 4x mini-DisplayPort 1.4a.

Architecture Differences

The architectural split is fundamental. The NVIDIA TITAN X Pascal is built on the Pascal architecture using the GP102 chip, fabricated on a 16 nm process at TSMC. It contains 11,800 million transistors on a 471 mm² die, resulting in a transistor density of 25.1M per mm². The AMD Radeon Pro WX 8200 uses the GCN 5.0 architecture with the Vega 10 chip, fabricated on a 14 nm process at GlobalFoundries. It contains 12,500 million transistors on a 495 mm² die, giving a density of 25.3M per mm². This makes the AMD chip slightly larger and denser, but the process node is older.

The memory technology is a defining architectural difference. The TITAN X Pascal uses GDDR5X, which is a mature, high-speed memory standard, while the Radeon Pro WX 8200 uses HBM2, which is a stacked memory standard offering much higher bandwidth per pin. This is reflected in the bus widths: 384-bit for GDDR5X versus 2048-bit for HBM2. The HBM2 implementation also contributes to the AMD card’s lower TDP despite a larger die.

Feature support differs in important ways. Both cards support DirectX 12 (12_1) and OpenGL 4.6. However, the TITAN X Pascal supports Vulkan 1.4, while the Radeon Pro WX 8200 supports Vulkan 1.3. This newer Vulkan version on the NVIDIA card may contribute to its superior Vulkan benchmark performance. Neither card has dedicated ray tracing or tensor cores, as both predate those hardware features. The FP16 compute ratio is starkly different: the TITAN X Pascal runs FP16 at a 1:64 ratio, meaning it is severely handicapped for half-precision work, while the Radeon Pro WX 8200 runs at a 2:1 ratio, making them effectively equal in FP16 and FP32 throughput.

The release timeline and market positioning also reflect architectural generation gaps. The TITAN X Pascal was released in August 2016 as part of the GeForce 10 generation, succeeding the GeForce 900 series and preceding the GeForce 20 series. The Radeon Pro WX 8200 was released in August 2018 as part of the Radeon Pro Polaris (WX x200) generation, succeeding Radeon Pro GCN and preceding Radeon Pro Vega. This two-year gap explains the newer process node and memory technology in the AMD card, though the NVIDIA card’s higher boost clock helps it compete.

The Verdict

The data supports a clear split decision based on workload. For users who primarily run Vulkan-based applications, games, or real-time rendering workloads, the NVIDIA TITAN X Pascal is the definitive choice. Its 12.2% Vulkan benchmark lead is decisive, and its 12 GB of memory provides more headroom for large assets. The higher boost clock of 1531 MHz also helps in lightly-threaded workloads that depend on single-core performance.

For users who rely on OpenCL compute, scientific simulation, or FP16-accelerated machine learning, the AMD Radeon Pro WX 8200 is the better option. Its 4.4% OpenCL advantage is consistent, and its 21.50 TFLOPS FP16 capability is in a completely different class from the TITAN X Pascal’s 171.5 GFLOPS, making it essential for any half-precision workload. The lower TDP of 230 W also makes it easier to integrate into power-constrained systems.

If you are building a system for mixed workloads, the average benchmark scores suggest the NVIDIA card has a slight overall edge, with a 72,098 average versus 69,870 for AMD, and a higher percentile rank. However, this advantage is driven almost entirely by the Vulkan result. In pure compute terms, the AMD card is competitive or superior. The choice ultimately comes down to which API and precision format your software stack prioritizes. Given that both cards are end-of-life, availability and driver support for your specific applications should be the deciding factor, but from a pure performance standpoint, each card has a clear domain of dominance.
