NVIDIA GeForce GTX TITAN Z vs NVIDIA Quadro RTX 5000 Comparison

The NVIDIA GeForce GTX TITAN Z and the NVIDIA Quadro RTX 5000 represent two distinct generations of professional and high-end computing. The data shows a decisive generational shift, with the Quadro RTX 5000 delivering vastly superior performance in the available benchmarks. In the Geekbench OpenCL test, the Quadro RTX 5000 scores 78,999 against the GTX TITAN Z’s 25,465, a delta of -67.8% from the perspective of the older card. The gap widens in the Geekbench Vulkan test, where the Quadro RTX 5000 achieves 92,309 points compared to the GTX TITAN Z’s 22,006, a -76.2% delta. The head-to-head record is 2 wins for the Quadro RTX 5000 and 0 for the GTX TITAN Z.

Head-to-Head Benchmarks

The benchmark results are unambiguous. The Quadro RTX 5000 outperforms the GTX TITAN Z by a massive margin in both recorded tests. In Geekbench OpenCL, the Quadro RTX 5000’s score of 78,999 is over three times higher than the GTX TITAN Z’s 25,465. This represents a 67.8% deficit for the GTX TITAN Z, indicating that the newer card is substantially more capable in compute-heavy OpenCL workloads. The performance gap is even more pronounced in the Vulkan API. The Quadro RTX 5000 posts a score of 92,309, while the GTX TITAN Z manages only 22,006. The delta here is 76.2%, meaning the Quadro RTX 5000 is roughly four times faster in this test. These are not marginal differences; they are generational leaps that completely redefine the expected performance envelope.

Looking at the broader context, the GTX TITAN Z’s average benchmark score is 23,736, which places it near the NVIDIA GeForce RTX 3080 Mobile (23,628, a 0.5% delta) and the AMD Radeon RX 9070 (23,877, a -0.6% delta). The Quadro RTX 5000’s average score of 21,629 is lower than its individual benchmark results suggest, pulling it into a different competitive tier. It sits closest to the NVIDIA GeForce GTX 1060 6 GB (21,856, a -1% delta) and the NVIDIA RTX A4000 Mobile (21,379, a 1.2% delta). This discrepancy highlights that the Quadro RTX 5000’s average is dragged down by its low Passmark scores, which are not representative of its OpenCL and Vulkan strength. The GTX TITAN Z’s average is more consistent with its two benchmark results, showing a balanced profile across different APIs.

The wins are all one-sided. The Quadro RTX 5000 wins both head-to-head matchups, with no test favoring the GTX TITAN Z. The sheer scale of the victory in Vulkan—a 76.2% delta—suggests architectural superiority that goes beyond raw clock speeds. The GTX TITAN Z’s best result, its OpenCL score of 25,465, is still far below the Quadro RTX 5000’s worst result in the same test. This indicates that the older card is not merely slower; it is fundamentally outclassed in modern compute and graphics workloads.

Architecture Differences

The architectural divide is stark. The GTX TITAN Z is built on the Kepler architecture, specifically the GK110B chip, manufactured on a 28 nm process at TSMC. It packs 7,080 million transistors into a 561 mm² die, yielding a transistor density of 12.6M / mm². The Quadro RTX 5000 uses the Turing architecture with the TU104 chip, built on a 12 nm process, also at TSMC. It contains 13,600 million transistors on a slightly smaller 545 mm² die, achieving a much higher density of 25.0M / mm². This nearly doubles the transistor count in a similar physical footprint, explaining the performance leap.

The memory subsystems are completely different generations. The GTX TITAN Z has 6 GB of GDDR5 memory on a 384-bit bus, delivering 336.0 GB/s of bandwidth. The Quadro RTX 5000 offers 16 GB of GDDR6 memory on a 256-bit bus, but with a higher 1750 MHz memory clock (14 Gbps effective) it achieves 448.0 GB/s of bandwidth. Despite the narrower bus, the newer memory type provides over 33% more bandwidth. The GTX TITAN Z’s memory clock is listed as 1750 MHz (7 Gbps effective), which is the same base frequency but half the effective data rate of the Quadro RTX 5000.

Compute resources differ significantly in configuration. The GTX TITAN Z has 2,880 shading units, 240 texture mapping units (TMUs), and 48 raster output units (ROPs). The Quadro RTX 5000 has 3,072 shading units (a 6.7% increase), but only 192 TMUs (a 20% decrease) and 64 ROPs (a 33% increase). The Quadro RTX 5000 also introduces 48 RT cores and 384 tensor cores, features entirely absent from the Kepler-based GTX TITAN Z. These dedicated hardware units enable ray tracing and AI-accelerated workloads that the older card cannot handle at all.

Clock speeds show a massive difference. The GTX TITAN Z runs at a 705 MHz base clock and 876 MHz boost, while the Quadro RTX 5000 operates at 1620 MHz base and 1815 MHz boost. This more than doubles the boost clock, contributing to the Quadro RTX 5000’s pixel rate of 116.2 GPixel/s versus the GTX TITAN Z’s 52.56 GPixel/s. The texture rate also favors the newer card: 348.5 GTexel/s versus 210.2 GTexel/s, despite the TMU count disadvantage. FP32 performance is 11.15 TFLOPS for the Quadro RTX 5000 against 5.046 TFLOPS for the GTX TITAN Z. The Quadro RTX 5000 also offers FP16 at 22.30 TFLOPS (2:1), which the GTX TITAN Z lacks entirely.

Power and physical requirements also diverge. The GTX TITAN Z has a 375 W TDP, requires a 750 W suggested PSU, and uses a triple-slot cooler with two 8-pin power connectors. The Quadro RTX 5000 is far more efficient at 230 W TDP, needing only a 550 W PSU and a dual-slot cooler with a single 6-pin and 8-pin connector. Both cards are 267 mm long and 111 mm tall, but the GTX TITAN Z is 62 mm wide while the Quadro RTX 5000’s width is not specified. The API support shows the Quadro RTX 5000 supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the GTX TITAN Z is limited to DirectX 12 (11_1) and Vulkan 1.2.175. Both support OpenGL 4.6.

The Verdict

The data is clear: the NVIDIA Quadro RTX 5000 is the superior card for virtually any workload. Its benchmark scores are 67.8% and 76.2% higher than the GTX TITAN Z in OpenCL and Vulkan respectively. The architectural advantages—Turing vs Kepler, 12 nm vs 28 nm, dedicated RT and tensor cores—translate directly into massive real-world performance gains. The Quadro RTX 5000 also offers more memory (16 GB vs 6 GB), higher bandwidth (448.0 GB/s vs 336.0 GB/s), and better power efficiency (230 W vs 375 W TDP). The GTX TITAN Z’s only advantages are its higher transistor density per mm² (though this is a function of the smaller process) and its higher average benchmark score of 23,736 versus 21,629, which is misleading given its lower raw performance in the head-to-head tests.

For users prioritizing raw compute in OpenCL or Vulkan, the Quadro RTX 5000 is the only rational choice. Its scores are not just higher; they are in a different performance class. The GTX TITAN Z, with its 69th percentile ranking versus the Quadro RTX 5000’s 67th, appears competitive on paper, but the percentile does not reflect the specific benchmark results. The GTX TITAN Z’s nearest rivals include the RTX 3080 Mobile and RX 9070, while the Quadro RTX 5000 sits near the GTX 1060 6 GB and RTX A4000 Mobile, indicating that its average is skewed by weaker Passmark scores. However, for the two benchmarks that matter most, the Quadro RTX 5000 wins decisively.

The GTX TITAN Z is an end-of-life product from 2014, while the Quadro RTX 5000 is from 2018. The newer card is the clear winner, and the data does not support any scenario where the GTX TITAN Z is preferable for modern compute tasks. The Quadro RTX 5000’s support for DirectX 12 Ultimate and Vulkan 1.4 also ensures compatibility with current software standards, whereas the GTX TITAN Z is limited to older APIs. Users with legacy workloads that specifically require Kepler architecture might consider the GTX TITAN Z, but the benchmark data provides no evidence of any performance advantage.

Where Each One Wins

The Quadro RTX 5000 wins every benchmark category where both cards are tested. In Geekbench OpenCL, it wins with a 67.8% margin, and in Geekbench Vulkan, it wins with a 76.2% margin. These are the only head-to-head tests available, and the Quadro RTX 5000 dominates both. The GTX TITAN Z has no benchmark wins in this comparison. However, the GTX TITAN Z does have a higher average benchmark score (23,736 vs 21,629) and a higher percentile ranking (69 vs 67). This is because the Quadro RTX 5000’s Passmark scores are relatively low, such as 113 in DirectX 10 and 59 in DirectX 12, which drag down its average. The GTX TITAN Z has no Passmark scores listed, so its average is based solely on its two strong Geekbench results.

For compute-heavy workloads using OpenCL or Vulkan, the Quadro RTX 5000 is the clear winner. Its higher bandwidth (448.0 GB/s vs 336.0 GB/s) and FP32 performance (11.15 TFLOPS vs 5.046 TFLOPS) support this conclusion. The Quadro RTX 5000 also has FP16 capability at 22.30 TFLOPS, which the GTX TITAN Z lacks, making it suitable for AI and machine learning tasks that leverage tensor cores. The GTX TITAN Z’s higher average score might appeal to users looking at overall synthetic benchmarks, but this is misleading when individual tests are examined. The GTX TITAN Z’s nearest rival, the RTX 3080 Mobile, is only 0.5% away in average score, while the Quadro RTX 5000’s nearest rival is the GTX 1060 6 GB at -1%. This suggests the GTX TITAN Z is closer to modern mobile GPUs, while the Quadro RTX 5000’s average is an outlier due to its Passmark results.

In terms of power efficiency, the Quadro RTX 5000 wins decisively, delivering higher performance at a 145 W lower TDP. This makes it more suitable for dense workstation environments. The GTX TITAN Z’s triple-slot cooler and 375 W TDP require more physical space and power delivery, limiting its deployment options. The Quadro RTX 5000’s dual-slot design and single 6-pin plus 8-pin connector are more flexible. For display outputs, the Quadro RTX 5000 offers 4x DisplayPort 1.4a and 1x USB Type-C, while the GTX TITAN Z has 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2. The newer card supports more modern display interfaces.
