NVIDIA GeForce GTX TITAN X vs NVIDIA GeForce RTX 5070 Mobile Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive generational shift when comparing the NVIDIA GeForce GTX TITAN X against the NVIDIA GeForce RTX 5070 Mobile. Across the two recorded head-to-head tests, the RTX 5070 Mobile wins both, but the margin of victory is far from uniform.

In Geekbench OpenCL, the RTX 5070 Mobile scores 122,238 against the GTX TITAN X’s 41,471. That represents a 66.1% advantage for the newer mobile part, which is a massive gap in raw compute throughput. The OpenCL test tends to stress general-purpose GPU compute, and the RTX 5070 Mobile’s Blackwell architecture, with its dedicated tensor cores and higher FP32 throughput, simply overwhelms the older Maxwell design.

The Geekbench Vulkan result is closer but still clearly favors the RTX 5070 Mobile. Here the scores are 116,960 for the RTX 5070 Mobile versus 49,397 for the GTX TITAN X, a 57.8% difference. Vulkan is a lower-level API that often rewards architectural efficiency and modern feature sets, and the RTX 5070 Mobile’s support for DirectX 12 Ultimate and newer hardware features gives it a distinct edge.

For context, the GTX TITAN X’s average benchmark score across all recorded tests is 36,530, which places it in the 80th percentile of all GPUs in the database. Its nearest rivals include the AMD Radeon RX 5300M (average score 36,529, a 0% delta), the NVIDIA T1000 (36,289, 0.7% ahead), the AMD Radeon PRO W6400 (37,157, 1.7% ahead), and the AMD Radeon Pro Duo (35,860, 1.9% behind). This shows the GTX TITAN X is competitive with modern entry-level parts, but it is no longer a top-tier performer.

The RTX 5070 Mobile, by contrast, has an average benchmark score of 29,928 across a much wider test suite, placing it in the 75th percentile. Its nearest rivals are all high-end desktop parts from the previous generation: the NVIDIA GeForce RTX 3070 Ti (29,945, 0.1% ahead), the NVIDIA GeForce RTX 2080 Ti (29,783, 0.5% behind), the AMD Radeon RX 6800 (30,095, 0.6% ahead), and the AMD Radeon RX 6700 (30,433, 1.7% ahead). The RTX 5070 Mobile effectively matches an RTX 3070 Ti in average performance, which is remarkable for a chip with a 50 W TDP.

The head-to-head data reveals a clear trend: the RTX 5070 Mobile is roughly 2.5 to 3 times faster than the GTX TITAN X in the two tests that were directly compared. The GTX TITAN X’s wins count is zero, while the RTX 5070 Mobile takes both.

Architecture Differences

The fundamental architectural gap between these two GPUs is enormous, spanning three major generational shifts. The GTX TITAN X is built on NVIDIA’s Maxwell 2.0 architecture, using the GM200 chip, fabricated on TSMC’s 28 nm process. It packs 8,000 million transistors on a die size of 601 mm², yielding a transistor density of 13.3 million per mm². This was a flagship desktop part designed for high power draw and maximum raw throughput.

The RTX 5070 Mobile uses Blackwell 2.0, the latest architecture, based on the GB206 chip, fabricated on TSMC’s 5 nm process. It integrates 21,900 million transistors on a much smaller die of 181 mm², achieving a density of 121.0 million per mm². That is roughly nine times the transistor density of the older chip, a direct result of the process node advancement.

The core configurations reflect this shift in design philosophy. The GTX TITAN X has 3,072 shading units, 192 texture mapping units, and 96 ROPs. It has no dedicated ray tracing cores or tensor cores, as these features were introduced in later architectures. The RTX 5070 Mobile, on the other hand, has 4,608 shading units, 144 TMUs, and only 48 ROPs, but it adds 36 ray tracing cores and 144 tensor cores. The lower TMU and ROP counts are typical of mobile parts, which prioritize efficiency and compute density over pixel-pushing capability.

The memory subsystems are also fundamentally different. The GTX TITAN X uses 12 GB of GDDR5 on a 384-bit bus, delivering 336.6 GB/s of bandwidth. The RTX 5070 Mobile uses 8 GB of GDDR7 on a 128-bit bus, but achieves 384.0 GB/s of bandwidth thanks to the much faster memory clock. The newer memory technology allows a narrower bus to outperform the wider one.

Compute throughput tells the story of the generational leap. The GTX TITAN X delivers 6.691 TFLOPS of FP32 performance, while the RTX 5070 Mobile delivers 13.13 TFLOPS, nearly double. The RTX 5070 Mobile also supports FP16 at a 1:1 rate (13.13 TFLOPS), which the GTX TITAN X does not record. Pixel rate is 104.5 GPixel/s for the older card versus 68.40 GPixel/s for the newer mobile chip, and texture rate is 209.1 GTexel/s versus 205.2 GTexel/s, showing that the GTX TITAN X retains some advantages in rasterization-specific tasks.

The API support also differs. The GTX TITAN X supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The RTX 5070 Mobile supports DirectX 12 Ultimate (12_2), which includes additional features like hardware ray tracing and mesh shaders, alongside OpenGL 4.6 and Vulkan 1.4.

Where Each One Wins

The GTX TITAN X is a product of its era, and its wins are narrow and specific. It has a higher pixel rate (104.5 GPixel/s versus 68.40 GPixel/s) and nearly double the ROP count (96 versus 48), which makes it potentially better suited for fill-rate-bound rasterization workloads that do not rely on compute. It also offers more memory capacity (12 GB versus 8 GB), which could be beneficial for large textures or datasets that fit within VRAM, though the bandwidth is lower. Its 384-bit bus is a classic desktop feature designed for high-bandwidth, high-latency workloads. In the database, its average score of 36,530 is actually higher than the RTX 5070 Mobile’s average score of 29,928, though this is skewed by the different test suites, as the mobile part runs many more Passmark tests that drag down its average. The GTX TITAN X also has a higher percentile ranking (80th versus 75th), indicating that across the entire database, it sits in a slightly stronger relative position.

The RTX 5070 Mobile wins in nearly every meaningful metric for modern workloads. It more than doubles FP32 compute (13.13 TFLOPS versus 6.691 TFLOPS), adds dedicated ray tracing and tensor cores, and uses a far more power-efficient process. Its 50 W TDP versus 250 W for the GTX TITAN X means it delivers vastly more performance per watt, a critical factor for mobile designs. The PCIe 5.0 x16 interface and DirectX 12 Ultimate support make it forward-compatible with next-generation software. In direct head-to-head benchmarks, it is 66.1% faster in OpenCL and 57.8% faster in Vulkan. Its memory bandwidth is higher (384.0 GB/s versus 336.6 GB/s) despite the narrower bus, and its memory clock is more than three times faster in effective terms.

For use-case segmentation, the GTX TITAN X is best suited for legacy DX11-era games, fill-rate-limited scenarios, or tasks that require large VRAM pools without needing modern compute features. The RTX 5070 Mobile is the clear choice for ray tracing, machine learning inference (thanks to tensor cores), modern API-heavy workloads, and any scenario where power consumption matters. For a laptop or compact system, the RTX 5070 Mobile is the only feasible option given its IGP form factor and lack of external power connectors. The GTX TITAN X remains a historical curiosity, a flagship that defined its generation, but the recorded data shows it is outclassed by a mobile chip released a decade later.
