NVIDIA GB10 vs NVIDIA TITAN X Pascal Comparison

The Verdict

The benchmark database presents a decisive picture: the NVIDIA GB10 outperforms the NVIDIA TITAN X Pascal in every recorded test, and by significant margins. The GB10 leads by 80.1% in Geekbench OpenCL and 47.9% in Geekbench Vulkan. For compute-oriented workloads, the GB10 is the clear choice. However, the TITAN X Pascal is not without its own strengths. The data shows it retains advantages in specific architectural features, such as a wider memory bus and higher pixel throughput, which may matter for particular legacy or rasterization-focused tasks. The verdict is not a blanket recommendation of one over the other, but a question of workload: the GB10 for raw modern compute performance and efficiency, the TITAN X Pascal for its unique characteristics that are absent in the newer part.

Architecture Differences

The two GPUs represent fundamentally different eras of NVIDIA design. The GB10 is built on the Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. The TITAN X Pascal uses the Pascal architecture on a 16 nm process. This process shrink is a core reason for the GB10's efficiency and density, though the die size is smaller at 382 mm² versus 471 mm² for the TITAN X Pascal.

The GB10 is a server-class part, part of the Server Blackwell (Bxx) generation, and it is packed with modern compute features. It includes 48 RT cores and 384 tensor cores, hardware that the TITAN X Pascal simply does not have. The TITAN X Pascal, belonging to the GeForce 10 generation, has no RT or tensor core support, reflecting its pre-ray tracing era design. The GB10 also has a much higher transistor density implicitly, given its smaller die and newer process, although exact transistor counts for the GB10 are not recorded.

In terms of shading and texture resources, the GB10 has 6,144 shading units and 384 TMUs, nearly double the TITAN X Pascal's 3,584 shading units and 224 TMUs. The TITAN X Pascal does counter with 96 ROPs, twice the GB10's 48, and a 384-bit memory bus versus 256-bit. The API support also diverges sharply: the TITAN X Pascal supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, while the GB10 reports N/A for all three, indicating its compute-focused, server-oriented nature rather than a graphics consumer product.

Specification Differences

The recorded specifications highlight a generational chasm. The GB10 operates with a base clock of 1665 MHz and a boost of 2418 MHz, significantly higher than the TITAN X Pascal's 1417 MHz base and 1531 MHz boost. Memory configurations differ starkly: the GB10 uses 128 GB of LPDDR5X with a 256-bit bus, achieving 273.2 GB/s, while the TITAN X Pascal uses 12 GB of GDDR5X with a 384-bit bus, delivering 480.4 GB/s. The TITAN X Pascal has higher raw bandwidth, but the GB10 has over ten times the capacity.

Compute throughput is a major differentiator. The GB10 delivers 29.71 TFLOPS FP32 and 29.71 TFLOPS FP16 (1:1 ratio), whereas the TITAN X Pascal offers 10.97 TFLOPS FP32 and only 171.5 GFLOPS FP16 (1:64 ratio). This makes the GB10 roughly 2.7 times faster in FP32 and dramatically faster in FP16 workloads. Power consumption is also divergent: the GB10 has a 140 W TDP with no power connectors, while the TITAN X Pascal draws 250 W and requires a 6-pin and 8-pin connector setup. The GB10 is an IGP form factor and is 150 mm long, while the TITAN X Pascal is a dual-slot card measuring 267 mm.

Physical and interface differences are notable. The GB10 uses PCIe 5.0 x16, while the TITAN X Pascal uses PCIe 3.0 x16. Display outputs vary: the GB10 has a single HDMI port, while the TITAN X Pascal has 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.4a. The production status also differs, with the GB10 marked as Active and the TITAN X Pascal as End-of-life. Release dates are far apart: the GB10 launched in October 2025, while the TITAN X Pascal launched in August 2016.

Head-to-Head Benchmarks

The recorded head-to-head results are unambiguous. In Geekbench OpenCL, the GB10 scores 120,137 against the TITAN X Pascal's 66,696, a delta of 80.1%. This is a massive margin, reflecting the GB10's superior compute resources, higher clocks, and newer architecture. In Geekbench Vulkan, the GB10 scores 114,648 versus 77,499, a 47.9% lead. While the Vulkan gap is smaller, it is still substantial.

The average benchmark scores reinforce this pattern. The GB10 averages 117,393, which places it at the 95th percentile of all GPUs. Its nearest rival, the AMD Radeon PRO W7700, scores 118,976, meaning the GB10 trails by 1.3%. It leads the NVIDIA RTX 4000 SFF Ada Generation by 0.3% and the NVIDIA Tesla V100 SXM2 16 GB by 2.6%. The TITAN X Pascal, averaging 72,098, sits at the 91st percentile. Its closest competitor, the AMD Radeon Pro Vega 64, is only 0.4% faster, while the AMD Radeon RX 6650M trails by 0.5%, and the AMD Radeon Vega Frontier Edition is 1.7% ahead.

The data indicates that the GB10's wins are not narrow. They are the result of a fundamentally different compute capability, particularly in FP16 and tensor operations, which the TITAN X Pascal cannot match. The TITAN X Pascal's only "wins" are in specific hardware features, not in any recorded benchmark score.

Where Each One Wins

The GB10 wins decisively in raw compute benchmarks. Its FP32 throughput of 29.71 TFLOPS versus 10.97 TFLOPS makes it ideal for general compute, scientific simulation, and any workload that leverages FP16 or tensor cores. The 128 GB memory capacity is suited for large datasets, AI model training, and in-memory databases, where the TITAN X Pascal's 12 GB would be a limiting factor. The GB10 also has a lower TDP of 140 W, making it more power-efficient per unit of performance, and it requires no external power connectors, simplifying deployment in dense server environments.

The TITAN X Pascal, despite its age, holds specific advantages. Its 384-bit memory bus and 480.4 GB/s bandwidth exceed the GB10's 273.2 GB/s, which could be beneficial for memory-bandwidth-bound tasks that fit within its 12 GB frame buffer. Its pixel rate of 147.0 GPixel/s is higher than the GB10's 116.1 GPixel/s, and with 96 ROPs, it may excel in certain rasterization or pixel-heavy legacy workloads. The TITAN X Pascal also supports DirectX 12, OpenGL 4.6, and Vulkan 1.4, making it a functional graphics card for gaming or consumer rendering, whereas the GB10 does not report these APIs, indicating a lack of traditional graphics driver support.

In practical terms, the database suggests the GB10 is for modern compute and AI workloads, while the TITAN X Pascal retains value only in niche scenarios where its memory bandwidth, pixel throughput, or legacy API support are paramount. For any general-purpose compute task, the GB10 is the superior choice by a wide margin.
