NVIDIA GeForce RTX 5070 Mobile vs NVIDIA RTX PRO 4500 Blackwell Comparison

The NVIDIA RTX PRO 4500 Blackwell and the NVIDIA GeForce RTX 5070 Mobile are both built on the Blackwell 2.0 architecture and the 5 nm TSMC process, but they occupy opposite ends of the GPU spectrum. The RTX PRO 4500 is a dual-slot workstation behemoth designed for maximum throughput, while the RTX 5070 Mobile is an integrated graphics processor (IGP) engineered for power efficiency in laptops. Benchmark data shows the desktop part dominating every test, but the mobile chip’s specifications reveal a device built for a fundamentally different purpose. The data indicates a clear hierarchy, yet the choice between them depends entirely on the intended system form factor and workload.

FAQ

Q: Which GPU has the higher average benchmark score?

A: The NVIDIA RTX PRO 4500 Blackwell has an average benchmark score of 31,532, compared to the NVIDIA GeForce RTX 5070 Mobile’s 29,928. This places the RTX PRO 4500 in the 76th percentile of all GPUs, while the RTX 5070 Mobile sits just behind in the 75th percentile.

Q: How much faster is the RTX PRO 4500 in compute workloads?

A: In the Passmark GPU Compute test, the RTX PRO 4500 scores 19,255, which is 132.6% higher than the RTX 5070 Mobile’s score of 8,279. This is the largest performance delta observed between the two cards in any benchmark.

Q: What is the difference in memory bandwidth?

A: The RTX PRO 4500 features a 256-bit memory bus with 32 GB of GDDR7 memory, delivering 896.0 GB/s of bandwidth. The RTX 5070 Mobile has a 128-bit bus with 8 GB of GDDR7 memory, providing 384.0 GB/s—less than half the bandwidth of the workstation card.

Q: Are these GPUs in the same performance class as other NVIDIA cards?

A: No. The RTX PRO 4500’s average score places it near the NVIDIA TITAN RTX, which scores 31,676 (a -0.5% delta). The RTX 5070 Mobile’s score is comparable to the NVIDIA GeForce RTX 3070 Ti, which scores 29,945 (a -0.1% delta), and the RTX 2080 Ti at 29,783 (a 0.5% delta).

Q: Does the RTX 5070 Mobile win any benchmark comparisons?

A: No. Across all eight head-to-head benchmark tests—including Geekbench Vulkan and all Passmark tests—the RTX PRO 4500 wins every round. The wins tally is 8 for the RTX PRO 4500 and 0 for the RTX 5070 Mobile.

Q: What are the power requirements for each card?

A: The RTX PRO 4500 has a TDP of 200 W and requires a 550 W power supply, using a single 16-pin connector. The RTX 5070 Mobile has a TDP of just 50 W and uses no power connectors, as it is integrated into a portable device.

Architecture Differences

The two GPUs share the same Blackwell 2.0 architecture and are fabricated by TSMC on a 5 nm process, but their internal configurations diverge sharply. The RTX PRO 4500 uses the GB203 chip, which contains 45,600 million transistors on a 378 mm² die, yielding a transistor density of 120.6 million per square millimeter. In contrast, the RTX 5070 Mobile uses the GB206 chip, packing 21,900 million transistors onto a much smaller 181 mm² die, with a slightly higher density of 121.0 million per square millimeter. The desktop part’s larger die accommodates substantially more execution resources: 10,496 shading units versus 4,608, 328 texture mapping units versus 144, and 112 ROPs versus 48. Ray tracing and tensor core counts follow the same pattern, with the RTX PRO 4500 offering 82 RT cores and 328 tensor cores, while the mobile chip has 36 RT cores and 144 tensor cores.

Clock speeds further separate the two. The RTX PRO 4500 runs at a base clock of 1635 MHz and boosts to 2407 MHz, whereas the RTX 5070 Mobile operates at a much lower 907 MHz base and 1425 MHz boost. This combination of more cores and higher clocks results in a massive compute advantage: the RTX PRO 4500 delivers 50.53 TFLOPS of FP32 and FP16 performance, while the RTX 5070 Mobile manages 13.13 TFLOPS in both. Memory architecture also differs, with the workstation card using a 256-bit bus and the mobile card a 128-bit bus, leading to a fill rate disparity—the RTX PRO 4500 achieves 269.6 GPixel/s and 789.5 GTexel/s, versus 68.40 GPixel/s and 205.2 GTexel/s for the mobile part. Physical specifications reflect their intended environments: the RTX PRO 4500 is dual-slot, 267 mm long, and 40 mm wide, while the RTX 5070 Mobile is an IGP with dimensions dependent on the portable device.

Head-to-Head Benchmarks

The benchmark data shows a decisive sweep, but the margins vary significantly across workloads. The most lopsided result comes from the Passmark GPU Compute test, where the RTX PRO 4500 scores 19,255 against the RTX 5070 Mobile’s 8,279—a 132.6% advantage. This test highlights the workstation card’s raw parallel processing capability, which is over double that of the mobile chip. Geekbench Vulkan also shows a substantial gap, with the RTX PRO 4500 scoring 221,768 versus 116,960, a 89.6% difference. This suggests that the desktop part excels in graphics API-heavy tasks, likely aided by its higher clock speeds and larger memory bandwidth.

DirectX benchmarks follow a similar trend. In Passmark DirectX 11, the RTX PRO 4500 scores 320, which is 66.7% higher than the RTX 5070 Mobile’s 192. The DirectX 9 test shows an 85.5% delta, with scores of 397 and 214, respectively. DirectX 12 presents the narrowest margin of victory: the RTX PRO 4500 scores 119, only 28% above the mobile card’s 93. This closer result indicates that the RTX 5070 Mobile’s architecture is relatively more competitive in modern, low-level API workloads, though it still loses decisively. The Passmark DirectX 10 test shows the RTX PRO 4500 at 204, a 58.1% lead over the 129 scored by the RTX 5070 Mobile.

The 3D graphics tests reinforce the pattern. Passmark G3D gives the RTX PRO 4500 a score of 33,360, which is 63.9% higher than the RTX 5070 Mobile’s 20,355. Even in the 2D test, the workstation card wins with a score of 1,336 versus 896—a 49.1% advantage. Across all eight tests, the RTX PRO 4500 never posts a margin below 28%, and the average superiority is substantial. The data shows no scenario where the RTX 5070 Mobile’s lower power envelope translates into competitive performance; the desktop card’s sheer resource count and clock speed advantages are insurmountable.

The Verdict

The performance hierarchy is unambiguous: the NVIDIA RTX PRO 4500 Blackwell is categorically faster than the NVIDIA GeForce RTX 5070 Mobile in every measurable benchmark. Its 50.53 TFLOPS of FP32 throughput, 896.0 GB/s of memory bandwidth, and 32 GB of GDDR7 memory make it a clear choice for workloads that demand maximum compute, such as rendering, simulation, or AI inference. The data shows it outperforms the mobile chip by over 130% in compute tests and by nearly 90% in Vulkan graphics, making it the only rational pick for a stationary workstation where power draw of 200 W and a 550 W PSU are acceptable constraints.

However, the RTX 5070 Mobile is not without merit, provided the context is a laptop. Its 50 W TDP and lack of power connectors make it suitable for portable devices, and its 8 GB of GDDR7 memory on a 128-bit bus is sufficient for mainstream gaming or creative work on the go. Its benchmark scores, while far lower, still place it in the 75th percentile of all GPUs, matching the performance level of desktop cards like the RTX 3070 Ti and RTX 2080 Ti. For a user prioritizing battery life and mobility over raw performance, the RTX 5070 Mobile is the only viable option, as the RTX PRO 4500’s dual-slot size and 267 mm length preclude any mobile integration.

The choice, therefore, is not about which GPU is better—the RTX PRO 4500 wins that argument outright—but about which system form factor the user requires. A desktop workstation should pair with the RTX PRO 4500, leveraging its 76th percentile standing and superior memory capacity. A laptop must use the RTX 5070 Mobile, accepting its lower scores in exchange for portability. The verdict from the data is that these cards serve separate markets, and the performance gap is a direct consequence of their different power budgets and physical designs.
