NVIDIA GeForce RTX 4070 Mobile vs NVIDIA TITAN RTX Comparison

Where Each One Wins

The recorded data shows a clear, though not overwhelming, pattern: the NVIDIA TITAN RTX wins all nine head-to-head benchmark comparisons against the GeForce RTX 4070 Mobile. There is no single test in the database where the mobile part takes the lead. However, the magnitude of those wins varies sharply by workload, which matters more than the raw win count.

For compute-heavy and API-level workloads, the TITAN RTX is decisively ahead. Its largest margin comes in Geekbench OpenCL, where it scores 144858 against 109197 for the RTX 4070 Mobile, a 32.7% advantage. Geekbench Vulkan shows a similar story with a 25.6% gap, with scores of 136073 versus 108367. Passmark GPU Compute also favors the desktop card by 19.5%, with scores of 10034 and 8399. These are not marginal differences; the TITAN RTX effectively dominates in tasks that stress raw shader throughput and general-purpose processing.

The picture changes in legacy DirectX tests. Passmark DirectX 9 shows a tie at 223 for both cards. Passmark DirectX 12 has the TITAN RTX ahead by only 3.5% (88 versus 85), and DirectX 11 shows a modest 5.6% lead (189 versus 179). These small deltas suggest that in older or more modern but lightly threaded API paths, the two GPUs perform nearly identically despite their architectural differences.

The middle ground belongs to Passmark G3D, the closest overall gaming-style metric. The TITAN RTX scores 20491 versus 19587, a 4.6% lead. Passmark DirectX 10 sits between the close mid-range results and the compute gap: 147 versus 147 for the desktop card, a 26.7% lead. Passmark G2D, a measure of 2D rasterization throughput, shows the TITAN RTX ahead by 12.7% (860 versus 763).

In short, the TITAN RTX wins on every recorded workload. The RTX 4070 Mobile cannot claim a single benchmark victory, but its losses in DirectX 9, DirectX 12 and DirectX 11 are small enough that the mobile part remains competitive in those specific paths. The compute and Vulkan and OpenCL margins, on the other hand, are where the TITAN RTX separates itself from the laptop part by a meaningful amount.

Architecture Differences

Architecture Differences

The two GPUs belong to entirely different NVIDIA generations and physical designs. The TITAN RTX uses the TU102 chip on a 12 nm TSMC process, with a die size of 754 mm² and 18,600 million transistors. The RTX 4070 Mobile uses the AD106 chip on TSMC's 5 nm process node, packing 22,900 million transistors into a much smaller 188 mm² die. Transistor density tells the tale: the AD106 reaches 121.8 million transistors per mm² versus the TU102's 24.7 million per mm². This is a fundamental shift in manufacturing efficiency, not just a simple die shrink.

Memory capacity is a major differentiator. The TITAN RTX carries 24 GB of GDDR6 across a 384-bit bus, delivering 672.0 GB/s of bandwidth. The RTX 4070 Mobile halves the memory to 8 GB on a 128-bit bus, dropping bandwidth to 256.0 GB/s. The desktop card has three times the memory and nearly three times the bandwidth. Both use GDDR6 memory type, and both list memory clocks of 1750 MHz and 2000 MHz respectively, with 14 Gbps and 16 Gbps effective rates. Note that the desktop TITAN RTX memory clock is listed as 1750 MHz with 14 Gbps effective, while the RTX 4070 Mobile lists 2000 MHz with 16 Gbps effective. The bandwidth advantage belongs to the TITAN RTX though.

Shading unit counts are identical at 4608 units on both cards. But the rest of the pipeline differs. The TITAN RTX has 288 texture mapping units and 96 ROPs, while the RTX 4070 Mobile halves those to 144 TMUs and 48 ROPs. The TITAN RTX has 72 ray tracing cores and 576 tensor cores; the mobile part offers 36 RT cores and 144 tensor cores. The TITAN RTX's pixel rate is 169.9 GPixel/s and texture rate 509.8 GTexel/s, versus 81.36 GPixel/s and 244.1 GTexel/s on the RTX 4070 Mobile.

The FP32 compute figures are close on paper: 16.31 TFLOPS for the TITAN RTX versus 15.62 TFLOPS for the RTX 4070 Mobile. But FP16 differs sharply. The TITAN RTX reaches 32.62 TFLOPS with a 2:1 ratio, while the RTX 4070 Mobile stays at 15.62 TFLOPS with a 1:1 ratio. The desktop card's FP16 capability is roughly double its FP32, while the mobile part has no such acceleration.

Power and physical design separate the two completely. The TITAN RTX has a 280 W TDP, is a dual-slot card, uses two 8-pin power connectors, and requires a 600 W suggested PSU. It measures 267 mm in length, 116 mm in height, and 35 mm in width. The RTX 4070 Mobile is an IGP with a 115 W TDP, no power connectors, no suggested PSU, and no listed dimensions. It uses PCIe 4.0 x8 while the TITAN RTX uses PCIe 3.0 x16. Display outputs also differ: the TITAN RTX has 1x HDMI 2.0, 3x DisplayPort 1.4a, and 1x USB Type-C, while the RTX 4070 Mobile's display outputs are portable device dependent.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The TITAN RTX is end-of-life and was released on 2018-12-17. The RTX 4070 Mobile is active and released on 2023-01-02. The TITAN RTX has a launch MSRP of 2,499 USD. The RTX 4070 Mobile has no listed launch MSRP.

Head-to-Head Benchmarks

The largest delta in the entire comparison is Geekbench OpenCL. The TITAN RTX scores 144858, the RTX 4070 Mobile 109197. That is a 32.7% lead, the single biggest margin in the dataset. The compute-focused Passmark GPU Compute test reinforces this with a 19.5% edge, 10034 versus 8399.

Geekbench Vulkan shows the TITAN RTX at 136073 against 108367, a 25.6% difference. This is a clear win for the desktop part in modern graphics API workloads. Passmark DirectX 10 follows a similar path, with the TITAN RTX at 147 versus 116, a 26.7% gap.

Passmark G3D is the closest major gaming metric. The TITAN RTX scores 20491, the RTX 4070 Mobile 19587, a 4.6% lead. Passmark G2D shows a 12.7% edge, 860 versus 763. Passmark DirectX 11 shows a 5.6% margin, 189 versus 179. Passmark DirectX 12 shows a 3.5% margin, 88 versus 85. Passmark DirectX 9 is a tie at 223.

The deltas are telling. The TITAN RTX wins DirectX 9 by exactly 0%, DirectX 12 by 3.5%, DirectX 11 by 5.5%. These small margins indicate that in the DirectX 9 through 12 range, the two GPUs are nearly indistinguishable. The 19.5% to 32.7% margins in compute and Vulkan and OpenCL show where the TITAN RTX truly excels.

The average benchmark score for the TITAN RTX is 31676, while the RTX 4070 Mobile averages 27435. That is a difference of roughly 4241 points, or about 15.5% of the mobile score. The percentile ranks also differ: the TITAN RTX sits at the 76th percentile among all GPUs, while the RTX 4070 Mobile sits at the 73rd. The nearest rivals for the TITAN RTX include the NVIDIA RTX PRO 4500 Blackwell at an average score of 31532 with a delta of 0.5%, and the Intel Arc Pro A30M at 31894 with a delta of -0.7%. The RTX 4070 Mobile's nearest rivals include the AMD Radeon RX 6700 XT at 27425 with a delta of 0%, and the NVIDIA GeForce RTX 3090 at 27565 with a delta of -0.5%. These figures indicate both cards perform near the level of much larger desktop GPUs, but the TITAN RTX holds a higher position in the overall distribution.

The Verdict

From the recorded data, the NVIDIA TITAN RTX is the stronger GPU overall. It wins every head-to-head benchmark, holds a higher average benchmark score of 31676 versus 27435, and ranks higher at the 76th percentile versus the 73rd. Its advantages are largest in compute and Vulkan and OpenCL workloads, where it leads by 19.5% to 32.7%. It also provides substantially more memory (24 GB versus 8 GB), more memory bandwidth (672.0 GB/s versus 256.0 GB/s), and more texture and pixel throughput.

The RTX 4070 Mobile is a far more efficient and compact part. It uses a 5 nm process with a 121.8 million transistor density per mm², consumes only 115 W versus 280 W, and fits as an IGP with no power connectors. Its FP32 performance is close to the TITAN RTX, at 15.62 TFLOPS versus 16.31 TFLOPS. In the DirectX 9 through 12 range, it trails by only 0% to 5.6%.

Users who need maximum compute performance, large memory capacity, and the highest possible FP16 throughput should choose the TITAN RTX. Users who need a mobile GPU that delivers near-desktop FP32 performance in a small power envelope should choose the RTX 4070 Mobile. The data does not support calling the mobile part a replacement for the TITAN RTX; it is a more efficient, more portable alternative that loses in every measured benchmark but stays close in several.
