NVIDIA RTX PRO 4500 Blackwell vs NVIDIA TITAN RTX Comparison

The NVIDIA TITAN RTX and the NVIDIA RTX PRO 4500 Blackwell are separated by over six years of architectural evolution, yet the benchmark data reveals a surprisingly close average performance gap. The TITAN RTX posts an average benchmark score of 31,676, while the RTX PRO 4500 Blackwell trails marginally at 31,532, a difference of just 0.5%. However, this near-parity in overall average masks a complete rout in individual tests, where the Blackwell card wins all nine head-to-head comparisons, often by substantial margins.

Head-to-Head Benchmarks

The most striking result is in the modern DirectX 12 workload, 3DMark Steel Nomad. The RTX PRO 4500 Blackwell scores 7,025, a commanding 46% lead over the TITAN RTX’s 3,794. This is not a marginal victory; it is a generational leap in raw rasterization throughput under contemporary API conditions. The gap is similarly pronounced in compute-heavy tasks. In Passmark’s GPU Compute test, the RTX PRO 4500 Blackwell delivers 19,255 points versus the TITAN RTX’s 10,034, a 47.9% advantage. This suggests the newer card’s architecture is far more efficient at handling parallel workloads that stress shader and tensor hardware.

Legacy DirectX performance tells the same story, albeit with smaller deltas. In Passmark DirectX 11, the RTX PRO 4500 Blackwell scores 320 against the TITAN RTX’s 189, a 40.9% improvement. The DirectX 9 test shows a 43.8% gap, with scores of 397 and 223 respectively. Even in DirectX 10, where the delta is smallest at 27.9% (204 vs 147), the Blackwell card still wins decisively. The pattern is clear: regardless of the API generation, the RTX PRO 4500 Blackwell outperforms the TITAN RTX.

The Vulkan results reinforce this trend. In Geekbench Vulkan, the RTX PRO 4500 Blackwell scores 221,768, which is 38.6% higher than the TITAN RTX’s 136,073. Interestingly, the TITAN RTX’s Vulkan score is notably lower than its OpenCL score of 144,858, suggesting its Turing architecture was less optimized for Vulkan’s explicit multi-threading model. The Blackwell card does not have a listed OpenCL benchmark, but its Vulkan dominance indicates superior driver and hardware support for modern low-level APIs.

Passmark’s 3D graphics suite (G3D) shows a 38.6% lead for the RTX PRO 4500 Blackwell, with 33,360 points versus 20,491. This is the most comprehensive rasterization test in the pack, and the result aligns with the 3DMark Steel Nomad outcome. Even the 2D graphics test (G2D) favors the newer card, with the RTX PRO 4500 Blackwell scoring 1,336 versus the TITAN RTX’s 860, a 35.6% difference. While 2D performance is rarely a bottleneck, it indicates the Blackwell card has faster memory and display pipeline throughput.

The only metric where the TITAN RTX does not lose is the average benchmark score itself, where its 31,676 edges out the RTX PRO 4500 Blackwell’s 31,532. This is a statistical artifact of the TITAN RTX having more benchmark entries (10 versus 9), including a strong Geekbench OpenCL result that is not present for the Blackwell card. In every directly comparable test, the RTX PRO 4500 Blackwell is the clear winner, with deltas ranging from 26.1% to 47.9%.

Architecture Differences

The architectural chasm between these two cards is vast. The TITAN RTX uses the TU102 chip built on TSMC’s 12 nm process, while the RTX PRO 4500 Blackwell uses the GB203 chip on a 5 nm node. This process shrink is the primary driver of efficiency and performance. Transistor density has jumped from 24.7 million per square millimeter on the TU102 to 120.6 million on the GB203. The TITAN RTX packs 18,600 million transistors on a massive 754 mm² die, whereas the RTX PRO 4500 Blackwell fits 45,600 million transistors on a much smaller 378 mm² die. This means the Blackwell chip crams over twice the transistors into half the area, enabling the 120.6M / mm² density figure.

Core counts differ dramatically. The RTX PRO 4500 Blackwell features 10,496 shading units, more than double the TITAN RTX’s 4,608. Texture mapping units also increase from 288 to 328, and ROPs from 96 to 112. Ray tracing cores are more numerous on the Blackwell card (82 vs 72), but the tensor core count is lower (328 vs 576). This is a notable divergence: the TITAN RTX has 576 tensor cores, while the RTX PRO 4500 Blackwell has only 328. Despite the lower count, the Blackwell tensor cores are likely newer generation hardware, but the raw number difference is significant.

Memory configurations reflect different design philosophies. The TITAN RTX uses 24 GB of GDDR6 on a 384-bit bus, yielding 672.0 GB/s of bandwidth. The RTX PRO 4500 Blackwell uses 32 GB of GDDR7 on a 256-bit bus, achieving 896.0 GB/s. The Blackwell card has 8 GB more capacity and 224 GB/s more bandwidth, despite the narrower bus, thanks to the faster GDDR7 memory running at 28 Gbps effective versus 14 Gbps on the TITAN RTX. Clock speeds also favor the newer card: the RTX PRO 4500 Blackwell boosts to 2407 MHz, versus 1770 MHz on the TITAN RTX.

Power and interface specifications differ as well. The TITAN RTX has a 280 W TDP and requires two 8-pin power connectors, while the RTX PRO 4500 Blackwell has a lower 200 W TDP with a single 16-pin connector. The suggested PSU is 600 W for the TITAN RTX and 550 W for the RTX PRO 4500 Blackwell. Bus interface jumps from PCIe 3.0 x16 to PCIe 5.0 x16. Display outputs also change: the TITAN RTX offers 1x HDMI 2.0, 3x DisplayPort 1.4a, and 1x USB Type-C, while the RTX PRO 4500 Blackwell provides 4x DisplayPort 2.1b.

The Verdict

The data is unambiguous. The NVIDIA RTX PRO 4500 Blackwell is the superior performer in every single benchmark test, with deltas ranging from 26.1% to 47.9%. Its wins in 3DMark Steel Nomad (46%), Passmark GPU Compute (47.9%), and Passmark G3D (38.6%) demonstrate dominance across synthetic rasterization, compute, and general 3D workloads. For anyone prioritizing raw performance in these tests, the RTX PRO 4500 Blackwell is the clear choice.

The TITAN RTX’s only advantage is its average benchmark score, which is 0.5% higher purely because it has an extra OpenCL benchmark entry. This is not a performance win; it is a data artifact. The TITAN RTX also has a higher tensor core count (576 vs 328), but given that the Blackwell card wins the compute test by nearly 48%, this numerical advantage does not translate into real-world compute superiority in the tested workloads.

The RTX PRO 4500 Blackwell also offers more memory (32 GB vs 24 GB), higher bandwidth (896.0 GB/s vs 672.0 GB/s), and a lower TDP (200 W vs 280 W). It is newer, active in production, and built on a more advanced 5 nm process. The TITAN RTX is end-of-life. Based strictly on benchmark performance, the RTX PRO 4500 Blackwell is the definitive winner, and the TITAN RTX should only be considered by users who specifically need its higher tensor core count for legacy workloads that are not represented in this benchmark suite.
