NVIDIA GeForce GTX TITAN X vs NVIDIA RTX PRO 4500 Blackwell Comparison

Where Each One Wins

The benchmark data splits these two cards across completely different eras of GPU testing. The GTX TITAN X was measured with Geekbench Metal, OpenCL, and Vulkan workloads, while the RTX PRO 4500 Blackwell was tested across a broader suite including 3DMark Steel Nomad, Passmark DirectX variants, and compute tests. This makes direct cross-card comparison possible only in the shared Geekbench Vulkan test, where the RTX PRO 4500 Blackwell dominates. The recorded data shows the newer card scoring 221768 in Vulkan, which is 77.7% ahead of the GTX TITAN X's 49397 score in the same test.

Looking at the GTX TITAN X's own benchmark results, it posts a Geekbench Metal score of 18723, an OpenCL score of 41471, and that Vulkan result of 49397. Its average benchmark score sits at 36530, placing it in the 80th percentile against all GPUs in the database. The RTX PRO 4500 Blackwell, by contrast, has an average benchmark score of 31532, which places it in the 76th percentile. The difference in average scores is misleading because the two cards were tested with different workloads, and the newer card's suite includes far more demanding DirectX 12 and compute tests.

The RTX PRO 4500 Blackwell wins in every modern workload category where it was measured. Its 3DMark Steel Nomad DX12 score of 7025 reflects strong current-generation rasterization performance. Passmark results show 33360 in G3D, 19255 in GPU compute, and 1336 in G2D. The older DirectX tests show lower scores: 397 in DirectX 9, 320 in DirectX 11, 204 in DirectX 10, and 119 in DirectX 12. These lower Passmark numbers likely reflect the test suite's behavior with newer architectures rather than a weakness in the GPU itself, since the same card scores far higher in the more demanding 3DMark Steel Nomad test.

The GTX TITAN X, with its 2015 release date, was tested only with Geekbench's cross-platform APIs. Its best result, 49397 in Vulkan, shows that even a high-end Maxwell card can run modern API workloads, but the gap to the Blackwell part is enormous. The 80th percentile ranking for the GTX TITAN X versus the 76th percentile for the RTX PRO 4500 Blackwell reflects the different test pools, not the relative performance of the two cards against each other.

Architecture Differences

The two cards come from opposite ends of NVIDIA's GPU design timeline. The GTX TITAN X uses the GM200 chip built on Maxwell 2.0 architecture, manufactured on a 28 nm process at TSMC. The RTX PRO 4500 Blackwell uses the GB203 chip on Blackwell 2.0 architecture, built on a 5 nm process, also at TSMC. The transistor counts tell the scaling story: the GTX TITAN X packs 8,000 million transistors on a 601 mm² die, giving a transistor density of 13.3M per mm². The RTX PRO 4500 Blackwell fits 45,600 million transistors on a smaller 378 mm² die, achieving 120.6M per mm². That is roughly a ninefold increase in transistor density.

The memory subsystems are generationally distinct as well. The GTX TITAN X has 12 GB of GDDR5 on a 384 bit bus, with memory clocked at 1753 MHz or 7 Gbps effective, producing 336.6 GB/s of bandwidth. The RTX PRO 4500 Blackwell offers 32 GB of GDDR7 on a 256 bit bus, with memory at 1750 MHz or 28 Gbps effective, delivering 896.0 GB/s. The bus width shrinks by a third, but the newer memory type more than compensates, nearly tripling bandwidth.

Compute resources scale dramatically. The GTX TITAN X has 3072 shading units, 192 texture mapping units, and 96 ROPs. The RTX PRO 4500 Blackwell has 10496 shading units, 328 TMUs, and 112 ROPs. The Blackwell card also adds 82 ray tracing cores and 328 tensor cores, features that did not exist in Maxwell. Pixel rate jumps from 104.5 GPixel/s to 269.6 GPixel/s, and texture rate climbs from 209.1 GTexel/s to 789.5 GTexel/s. FP32 throughput goes from 6.691 TFLOPS to 50.53 TFLOPS, a more than sevenfold increase. The RTX PRO 4500 Blackwell also has FP16 performance at 50.53 TFLOPS with a 1:1 ratio, while the GTX TITAN X has no recorded FP16 figure.

Clock speeds also moved forward. The GTX TITAN X runs at a 1000 MHz base and 1089 MHz boost. The RTX PRO 4500 Blackwell runs at 1635 MHz base and 2407 MHz boost. Power consumption, however, goes down: the TITAN X has a 250 W TDP with a 600 W suggested PSU, while the RTX PRO 4500 Blackwell has a 200 W TDP with a 550 W suggested PSU. The power connector changes from 1x 6-pin plus 1x 8-pin to a single 16-pin connector. Both cards are dual-slot and share the same 267 mm length and 111 mm height, with the RTX PRO 4500 Blackwell slightly thicker at 40 mm versus 38 mm.

Interface support differs as well. The GTX TITAN X uses PCIe 3.0 x16, while the RTX PRO 4500 Blackwell uses PCIe 5.0 x16. Display outputs move from 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.2 to 4x DisplayPort 2.1b. Both support DirectX 12, but the TITAN X is limited to 12 (12_1) while the Blackwell card supports 12 Ultimate (12_2). OpenGL and Vulkan support match at 4.6 and 1.4 respectively. The GTX TITAN X was released on 2015-03-16 with a 999 USD launch MSRP and is end-of-life, while the RTX PRO 4500 Blackwell was released on 2025-03-17, has no recorded launch MSRP, and remains active in production.

The Verdict

The choice between these two cards is not a difficult one based on the recorded data. The RTX PRO 4500 Blackwell is the superior GPU by every measurable metric. It has more shading units, more TMUs, more ROPs, higher clocks, more memory, faster memory, ray tracing cores, tensor cores, and dramatically higher compute throughput. Its Vulkan score of 221768 is 77.7% higher than the GTX TITAN X's 49397 in the same test, and it does all of this with a lower TDP of 200 W versus 250 W.

The GTX TITAN X's only advantages are historical. It was the flagship of the GeForce 900 generation, it has a wider 384 bit memory bus, and it was priced at 999 USD at launch. None of these matter in a modern comparison. Its average benchmark score of 36530 is actually higher than the RTX PRO 4500 Blackwell's 31532, but this is an artifact of different test suites. The Geekbench tests that the TITAN X ran are less demanding than the 3DMark Steel Nomad and Passmark tests that the Blackwell card ran.

Users who need modern features like hardware ray tracing, tensor core acceleration, or DirectX 12 Ultimate support have only one option here. The RTX PRO 4500 Blackwell provides all of those. Users working with large datasets or high-resolution textures will benefit from the 32 GB GDDR7 memory and 896.0 GB/s bandwidth. The GTX TITAN X, with its 12 GB GDDR5 and 336.6 GB/s bandwidth, cannot match that capacity or throughput.

The production status alone settles most arguments. The GTX TITAN X is end-of-life, while the RTX PRO 4500 Blackwell is active. The older card is a museum piece, the newer one is a current workstation product. The data shows no scenario where the GTX TITAN X wins a modern workload.

Head-to-Head Benchmarks

The only directly comparable benchmark result in the database is Geekbench Vulkan. The GTX TITAN X scores 49397, and the RTX PRO 4500 Blackwell scores 221768. That is a delta of 77.7% in favor of the Blackwell card. The Vulkan API is supported by both cards, with both listing Vulkan 1.4 support, so this is a clean apples-to-apples comparison of modern API performance.

Beyond that shared test, the RTX PRO 4500 Blackwell's results across its own benchmark suite paint a picture of a card that handles both rasterization and compute at high levels. Its 3DMark Steel Nomad DX12 score of 7025 indicates strong performance in a current-generation DirectX 12 workload. Passmark G3D at 33360 and GPU compute at 19255 show balanced raster and compute capabilities. The lower Passmark scores in older DirectX versions, ranging from 119 in DirectX 12 to 397 in DirectX 9, are curious but consistent with how newer architectures often perform in legacy API tests.

The GTX TITAN X's best result is its Geekbench OpenCL score of 41471, which is its strongest showing across the three tests it ran. Its Metal score of 18723 is the lowest of the three, reflecting the relative immaturity of Metal support for Maxwell-era hardware. Its Vulkan score of 49397 sits between those two.

Looking at the nearest rivals in the database puts both cards in context. The GTX TITAN X, with an average score of 49397 in Vulkan, has nearest rivals including the AMD Radeon RX 5300M at 36529, the NVIDIA T1000 at 36289, the AMD Radeon PRO W6400 at 37157, and the AMD Radeon Pro Duo at 35860. The deltas are small, ranging from 1.9% ahead of the Pro Duo to 1.7% behind the W6400. The RTX PRO 4500 Blackwell, meanwhile, with an average score of 31532 across its suite, has nearest rivals including the NVIDIA TITAN RTX at 31676, the NVIDIA GRID M60-1Q at 31220, the NVIDIA Quadro M5000 at 31206, and the Intel Arc Pro A30M at 31894. The deltas there range from 1% behind the TITAN RTX to 1.1% ahead of the Arc Pro A30M.

The overall percentile rankings, 80th percentile for the GTX TITAN X and 76th percentile for the RTX PRO 4500 Blackwell, should be read with caution. The different test suites mean these percentiles are not directly comparable across the two cards. What matters is the one test they share, where the Blackwell card is 77.7% ahead, plus the overwhelming architectural advantage in every compute metric. The RTX PRO 4500 Blackwell has 10496 shading units versus 3072, 328 TMUs versus 192, 112 ROPs versus 96, 50.53 TFLOPS FP32 versus 6.691, 896.0 GB/s bandwidth versus 336.6, and 32 GB memory versus 12. No single benchmark needs to be re-run to know which card is faster; the gap is structural.
