NVIDIA RTX PRO 4000 Blackwell vs NVIDIA TITAN RTX Comparison

Head-to-Head Benchmarks

The head-to-head benchmark data is decisively one-sided. The NVIDIA RTX PRO 4000 Blackwell wins all nine recorded comparisons, with no victories for the NVIDIA TITAN RTX in any test. The margins are substantial and consistent, pointing to a generational shift rather than a close contest.

The largest single victory for the RTX PRO 4000 Blackwell comes in the Passmark DirectX 9 test, where it scores 354 against the TITAN RTX's 223. That is a 37% deficit for the older card. Legacy API performance is often a weak point for newer architectures, but here the Blackwell card does not show that regression. It also dominates in Passmark DirectX 11, scoring 276 versus 189, a 31.5% gap. The compute-oriented workloads show similar separation: Passmark GPU Compute returns 14805 for the RTX PRO 4000 Blackwell versus 10034 for the TITAN RTX, a 32.2% difference.

The 3DMark Steel Nomad DX12 test, a modern DirectX 12 workload, shows the RTX PRO 4000 Blackwell at 4648 points against 3794 for the TITAN RTX. That 18.4% advantage is actually one of the narrower margins in this comparison, but it still represents a clear win. The Geekbench Vulkan score favors the newer card even more strongly: 194168 versus 136073, a 29.9% gap. This suggests the RTX PRO 4000 Blackwell handles both modern and legacy graphics APIs with greater efficiency.

Passmark DirectX 12 shows a smaller but still positive result for the RTX PRO 4000 Blackwell: 97 versus 88, a 9.3% edge. The DirectX 10 test follows the same pattern, with 173 versus 147, a 15% difference. The 2D performance test, Passmark G2D, gives the RTX PRO 4000 Blackwell a 1265 score against 860 for the TITAN RTX, a 32% improvement. The overall Passmark G3D score is 28427 versus 20491, translating to a 27.9% lead for the newer card.

What is striking is the uniformity of these wins. There is no test where the TITAN RTX manages to claw back even a small advantage. The closest margin is the DirectX 12 test at 9.3%, but even that is a clear loss. The data implies that the RTX PRO 4000 Blackwell is not just faster in peak throughput, but also more consistent across different rendering paths and compute models.

The Verdict

The verdict from the recorded data is unambiguous. The NVIDIA RTX PRO 4000 Blackwell wins every head-to-head benchmark, so any user choosing between these two cards should select the Blackwell model unless there is a specific reason to prefer the older card. The average benchmark score for the TITAN RTX is 31676, while the RTX PRO 4000 Blackwell sits at 27135. That is a notable reversal: the older card has a higher average score across all its recorded benchmarks, yet it loses in every direct comparison. This happens because the benchmark suites differ between the two entries, and the head-to-head tests are the ones that matter for direct comparison.

The percentile data also tells a nuanced story. The TITAN RTX sits at the 76th percentile among all GPUs, while the RTX PRO 4000 Blackwell is at the 72nd percentile. So in the broader database, the TITAN RTX ranks slightly higher against the entire field. But in direct competition, it loses every time. This is a case where the overall percentile ranking does not predict head-to-head results.

For a user who needs maximum performance in the specific workloads covered by these benchmarks, the RTX PRO 4000 Blackwell is the clear choice. It is also the only one still in active production; the TITAN RTX is marked as end-of-life. The newer card is not just faster, it is also more current, with a release date in 2025 versus 2018 for the TITAN RTX.

However, the TITAN RTX still has a role. Its higher average benchmark score and higher percentile ranking suggest it holds up well in other workloads not covered in the head-to-head set. The TITAN RTX also has a much larger die and higher transistor count, which may matter for certain compute tasks that scale with raw silicon area. But strictly from the head-to-head data, the RTX PRO 4000 Blackwell wins outright.

Architecture Differences

The architectural divide between these two cards is enormous. The TITAN RTX uses the TU102 chip built on Turing architecture, manufactured on a 12 nm process at TSMC. The RTX PRO 4000 Blackwell uses the GB203 chip on Blackwell 2.0 architecture, also from TSMC but on a 5 nm process. That process shrink is the foundation of nearly every performance difference.

The transistor counts tell the story of a generational leap. The TITAN RTX packs 18,600 million transistors on a 754 mm² die, yielding a density of 24.7 million transistors per square millimeter. The RTX PRO 4000 Blackwell has 45,600 million transistors on a much smaller 378 mm² die, giving it a density of 120.6 million transistors per square millimeter. The newer card has more than twice the transistor count in less than half the die area. This explains how it achieves higher performance while consuming less power.

The shading unit count reflects this density advantage. The TITAN RTX has 4608 shading units, while the RTX PRO 4000 Blackwell has 8960, nearly double. Texture mapping units are similar: 288 for the TITAN RTX versus 280 for the RTX PRO 4000 Blackwell, a slight reduction that does not hurt performance. Raster output units are identical at 96. Ray tracing cores are close as well, with 72 on the TITAN RTX and 70 on the RTX PRO 4000 Blackwell.

Tensor cores show a different pattern. The TITAN RTX has 576 tensor cores, while the RTX PRO 4000 Blackwell has only 280. This is a significant reduction in count, but the newer architecture likely compensates with higher per-core efficiency. The FP32 throughput reflects the shading unit difference: 16.31 TFLOPS for the TITAN RTX against 36.83 TFLOPS for the RTX PRO 4000 Blackwell. The FP16 numbers are also revealing. The TITAN RTX achieves 32.62 TFLOPS with a 2:1 ratio, while the RTX PRO 4000 Blackwell delivers 36.83 TFLOPS with a 1:1 ratio. That means the Blackwell card does not rely on double-rate FP16; it just computes at full speed.

Specification Differences

The specification sheet shows several key differences beyond the architecture. The memory configuration is one of the most striking. Both cards have 24 GB of memory, but the type differs: the TITAN RTX uses GDDR6, while the RTX PRO 4000 Blackwell uses GDDR7. The bus width also differs, with the TITAN RTX using a 384 bit bus and the RTX PRO 4000 Blackwell using a 192 bit bus. Despite the narrower bus, the newer card achieves the same 672.0 GB/s bandwidth because GDDR7 runs at a much higher effective speed. Both cards run memory at 1750 MHz, but the effective data rate is 14 Gbps for the TITAN RTX and 28 Gbps for the RTX PRO 4000 Blackwell.

Clock speeds differ in an interesting way. The TITAN RTX has a higher base clock at 1350 MHz versus 1230 MHz for the RTX PRO 4000 Blackwell. But the boost clock favors the newer card: 2055 MHz versus 1770 MHz. This means the RTX PRO 4000 Blackwell can ramp much higher under load, which helps explain its performance advantage.

Power consumption is dramatically lower on the newer card. The TITAN RTX has a TDP of 280 W, while the RTX PRO 4000 Blackwell uses only 140 W. The suggested power supply also drops from 600 W to 300 W. The physical design reflects this: the TITAN RTX is dual-slot with two 8-pin power connectors, while the RTX PRO 4000 Blackwell is single-slot with one 16-pin connector. The dimensions also shrink, with the TITAN RTX measuring 267 mm in length versus 241 mm for the newer card, and 35 mm in width versus 20 mm.

The bus interface has been upgraded from PCIe 3.0 x16 to PCIe 5.0 x16. Display outputs differ as well: the TITAN RTX offers 1x HDMI 2.0, 3x DisplayPort 1.4a, and 1x USB Type-C, while the RTX PRO 4000 Blackwell provides 4x DisplayPort 2.1b. The API support is identical, with both cards supporting DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Where Each One Wins

The RTX PRO 4000 Blackwell wins in every scenario covered by the head-to-head benchmarks. That includes modern DirectX 12 workloads, legacy DirectX 9 through 11, Vulkan, and compute tasks. It also wins in 2D performance, which is often overlooked but matters for desktop responsiveness and certain workstation tasks. The 9.3% margin in DirectX 12 is its smallest win, but it is still a definitive victory. The larger margins in DirectX 9 and DirectX 11 suggest the newer architecture handles older code paths more efficiently.

The TITAN RTX does not win any head-to-head test, but it is not without merit in the broader database. Its average benchmark score of 31676 is higher than the RTX PRO 4000 Blackwell's 27135, and its 76th percentile ranking beats the newer card's 72nd percentile. This implies that in benchmarks not covered by the head-to-head set, the TITAN RTX may still hold an advantage. The larger die size and higher transistor count could benefit workloads that are not represented in the nine compared tests.

For a user with a specific workload that appears only in the TITAN RTX's broader benchmark set, the older card might still be viable. Its higher FP16 throughput of 32.62 TFLOPS, even with the 2:1 ratio, is close to the newer card's 36.83 TFLOPS. The greater number of tensor cores, 576 versus 280, could also matter for AI inference tasks that rely on raw tensor core count rather than architectural efficiency.

But for any of the nine tested workloads, the choice is clear. The RTX PRO 4000 Blackwell is faster, uses less power, takes up less space, and is still in active production. The TITAN RTX is end-of-life, which means it will not receive future driver optimizations or support. The data does not support choosing the TITAN RTX for any of the compared benchmarks. It retains value only in workloads outside the head-to-head set, and even then, the newer card's architectural advantages make it the safer long-term pick.
