AMD Radeon RX 6950 XT vs NVIDIA TITAN X Pascal Comparison

The Verdict

The data separates these two cards into distinct eras of GPU design. The NVIDIA TITAN X Pascal, built on the 16 nm Pascal architecture, is an end-of-life product from 2016, while the AMD Radeon RX 6950 XT, a RDNA 2.0 part, launched in 2022. The recorded benchmark results make the outcome unambiguous: the RX 6950 XT wins both head-to-head comparisons, taking 2 out of 2 wins, while the TITAN X Pascal records zero wins. The RX 6950 XT leads by 67.6% in Geekbench OpenCL and by 53.1% in Geekbench Vulkan, which are massive margins. For any user choosing between these two based on the database, the RX 6950 XT is the clear pick for both compute workloads and graphics API performance. The TITAN X Pascal remains relevant only for those specifically needing its older feature set or its unique 384-bit memory bus, but the performance gap is too large to recommend it for general use.

Where Each One Wins

The AMD Radeon RX 6950 XT dominates every recorded benchmark in the head-to-head comparison. In Geekbench OpenCL, it scores 205,998 against the TITAN X Pascal's 66,696, a margin that reflects a 67.6% advantage. In Geekbench Vulkan, the RX 6950 XT scores 165,212 versus 77,499 for the TITAN, a 53.1% lead. There is no benchmark in the database where the TITAN X Pascal comes out ahead.

Looking at the broader benchmark suite, the RX 6950 XT also posts strong scores in other tests, including 222,653 in Geekbench Metal, 28,070 in Passmark G3D, and 14,199 in Passmark GPU Compute. The TITAN X Pascal only has two recorded benchmarks, both of which are the Geekbench OpenCL and Vulkan tests, so there is no additional data to show where it might excel. The closest competitor to the TITAN X Pascal in its nearest rival list is the AMD Radeon Pro Vega 64, which has an average score of 72,379, placing the TITAN X Pascal 0.4% behind. The TITAN X Pascal is also 1.7% behind the AMD Radeon Vega Frontier Edition, which scores 73,370. For the RX 6950 XT, its nearest rival is the NVIDIA P102-100 with an average score of 58,528, and the RX 6950 XT trails that by 0.2%. This indicates that the RX 6950 XT, despite its high peak scores, has a lower average benchmark score of 58,392, which places it in the 88th percentile of all GPUs, whereas the TITAN X Pascal sits in the 91st percentile with an average of 72,098. The average scores are skewed by the different sets of benchmarks available for each card, but the direct head-to-head tests are decisive.

Architecture Differences

The architectural gap between these two GPUs is substantial. The NVIDIA TITAN X Pascal uses the GP102 chip on a 16 nm process from TSMC, with 11,800 million transistors on a 471 mm² die, giving a transistor density of 25.1 million per mm². The AMD Radeon RX 6950 XT uses the Navi 21 chip on a 7 nm process, also from TSMC, with 26,800 million transistors on a 520 mm² die, achieving a much higher density of 51.5 million per mm². The newer process node allows the RX 6950 XT to pack more than twice the transistor count into a similar die size.

The RX 6950 XT has 5,120 shading units, 320 texture mapping units, and 128 render output units. The TITAN X Pascal has 3,584 shading units, 224 TMUs, and 96 ROPs. The RX 6950 XT also includes 80 ray tracing cores, a feature completely absent from the TITAN X Pascal. The TITAN X Pascal offers 10.97 TFLOPS of FP32 performance and only 171.5 GFLOPS of FP16 (at a 1:64 ratio), while the RX 6950 XT delivers 23.65 TFLOPS of FP32 and 47.31 TFLOPS of FP16 (at a 2:1 ratio). The RX 6950 XT's FP16 capability is over 275 times higher than the TITAN's.

Memory configurations also differ sharply. The TITAN X Pascal uses 12 GB of GDDR5X on a 384-bit bus, providing 480.4 GB/s of bandwidth. The RX 6950 XT uses 16 GB of GDDR6 on a 256-bit bus, but with a faster 18 Gbps effective memory speed, it reaches 576.0 GB/s of bandwidth. The RX 6950 XT also supports PCIe 4.0 x16, while the TITAN X Pascal is limited to PCIe 3.0 x16. The TITAN X Pascal's boost clock is 1531 MHz, while the RX 6950 XT boosts to 2310 MHz with a game clock of 2100 MHz.

The RX 6950 XT supports DirectX 12 Ultimate (12_2), while the TITAN X Pascal is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The TITAN X Pascal has a 250 W TDP with a dual-slot design and 1x 6-pin plus 1x 8-pin power connectors, while the RX 6950 XT has a 335 W TDP with a triple-slot design and 2x 8-pin connectors. The RX 6950 XT is physically taller and wider, measuring 120 mm in height and 50 mm in width versus 112 mm and 40 mm for the TITAN, though both are 267 mm in length. The TITAN X Pascal includes a DVI output, which the RX 6950 XT lacks; the RX 6950 XT offers one HDMI 2.1 and two DisplayPort 1.4a outputs, while the TITAN has one HDMI 2.0 and three DisplayPort 1.4a outputs.

FAQ

Q: Which card has higher raw compute performance?

A: The AMD Radeon RX 6950 XT delivers 23.65 TFLOPS of FP32 performance, more than double the TITAN X Pascal's 10.97 TFLOPS. The RX 6950 XT also provides 47.31 TFLOPS of FP16, while the TITAN X Pascal offers only 171.5 GFLOPS.

Head-to-Head Benchmarks

The database records two direct comparisons between the NVIDIA TITAN X Pascal and the AMD Radeon RX 6950 XT, and the results are one-sided. In the Geekbench OpenCL test, the RX 6950 XT scores 205,998, while the TITAN X Pascal manages only 66,696. This is a 67.6% difference in favor of the AMD card. The OpenCL workload benefits from the RX 6950 XT's higher shading unit count (5,120 versus 3,584) and its much higher FP32 throughput of 23.65 TFLOPS, which is roughly 2.16 times the TITAN's 10.97 TFLOPS. The delta percentage of -67.6% means the TITAN X Pascal is 67.6% behind the RX 6950 XT in this test.

The second test, Geekbench Vulkan, shows a similar pattern. The RX 6950 XT scores 165,212, and the TITAN X Pascal scores 77,499. The RX 6950 XT leads by 53.1%. Vulkan performance is influenced by the architectural improvements in RDNA 2.0, including the faster boost clock of 2310 MHz versus 1531 MHz and the larger memory bandwidth. The TITAN X Pascal's Vulkan score is still respectable, but it is not competitive with the newer AMD architecture.

Beyond the head-to-head tests, the RX 6950 XT shows strong performance in other recorded benchmarks that the TITAN X Pascal does not have data for. The RX 6950 XT scores 222,653 in Geekbench Metal, 28,070 in Passmark G3D, and 14,199 in Passmark GPU Compute. It also records scores in Passmark DirectX 9 (303), DirectX 10 (164), DirectX 11 (300), and DirectX 12 (114), as well as 1,063 in Passmark G2D. The TITAN X Pascal has no comparable entries in those tests, so a full comparison is impossible beyond the two shared workloads. However, the two tests that do overlap are the most important for cross-platform compute and graphics API performance, and the RX 6950 XT wins both decisively.

The average benchmark scores in the database tell a nuanced story. The TITAN X Pascal has an average score of 72,098 across its two benchmarks, placing it in the 91st percentile of all GPUs. The RX 6950 XT has an average score of 58,392 across eleven benchmarks, placing it in the 88th percentile. This discrepancy arises because the RX 6950 XT's average includes lighter workloads like Passmark DirectX 9 and Passmark G2D, which pull the mean down, while the TITAN X Pascal only has high-scoring Geekbench tests. The nearest rivals for the TITAN X Pascal include the AMD Radeon Pro Vega 64 at 72,379 (0.4% ahead), the AMD Radeon RX 6650M at 71,768 (0.5% behind), and the AMD Radeon Vega Frontier Edition at 73,370 (1.7% ahead). The RX 6950 XT's nearest rivals are the NVIDIA P102-100 at 58,528 (0.2% ahead), the Intel Arc A570M at 58,239 (0.3% behind), and the AMD Radeon RX 5600 OEM at 58,085 (0.5% behind). These lists show that the TITAN X Pascal sits among high-end workstation-class cards, while the RX 6950 XT's average is pulled down by its diverse test set, but the direct comparison leaves no doubt about which GPU is faster.
