NVIDIA GeForce RTX 5080 Mobile vs NVIDIA RTX PRO 4500 Blackwell Comparison

Head-to-Head Benchmarks

The benchmark comparison between the NVIDIA GeForce RTX 5080 Mobile and the NVIDIA RTX PRO 4500 Blackwell is remarkably one-sided. Across all nine recorded head-to-head tests, the RTX PRO 4500 Blackwell takes the win. The GeForce RTX 5080 Mobile does not secure a single victory in any of the shared workloads, making the performance gap consistent and structural rather than application-specific.

The largest difference appears in the Passmark GPU Compute test. The RTX PRO 4500 Blackwell scores 19,255, while the RTX 5080 Mobile scores 12,134. That is a 37% deficit for the mobile part, the biggest margin recorded in the entire comparison. This suggests the PRO card has a decisive advantage in raw compute throughput, which aligns with its role as a workstation-oriented product.

In the 3DMark Steel Nomad DX12 test, the RTX PRO 4500 Blackwell posts 7,025 points against the RTX 5080 Mobile's 4,952 points. That is a 29.5% difference, showing that the gap persists even in modern DirectX 12 gaming and workload scenarios. The GeForce falls behind by nearly a third in this test, which is a strong indicator of overall rasterization performance.

The Geekbench Vulkan result follows a similar pattern. The RTX PRO 4500 Blackwell reaches 221,768, while the RTX 5080 Mobile manages 169,754. The delta here is 23.5%. Vulkan is often used in both gaming and professional applications, so this result reinforces the idea that the PRO card is not just a compute specialist; it also holds a solid lead in API-level graphics workloads.

The legacy DirectX tests show smaller but still consistent margins. In Passmark DirectX 10, the PRO card scores 204 versus 171 for the mobile part, a 16.2% lead. In DirectX 11, the scores are 320 and 253, a 20.9% gap. DirectX 9 shows the same 20.9% difference, with 397 against 314. The DirectX 12 test is the closest of all, with the PRO card at 119 and the mobile at 116, a mere 2.5% difference. This near-parity in DirectX 12 is notable; it suggests that when both cards are pushed to their architectural limits under the newest API, the mobile part closes much of the distance.

The Passmark G3D score also favors the PRO card, 33,360 versus 27,711, a 16.9% lead. The 2D test shows a smaller margin, 1,336 against 1,095, an 18% difference. Even in 2D workloads, which are rarely the focus of high-end GPU comparisons, the workstation card comes out ahead.

It is notably the RTX 5080 Mobile's average benchmark score across all recorded tests is 38,349, while the RTX PRO 4500 Blackwell sits at 31,532. That seems contradictory given the head-to-head results, but the average includes a wider set of tests than the nine shared comparisons. The mobile card's nearest rival in the database is the GeForce MX570, with an average score of 38,299, a delta of only 0.1%. The RTX 4080 Mobile is also close, at 38,135, a 0.6% difference. The PRO card's nearest rival is the TITAN RTX at 31,676, a 0.5% delta, and the GRID M60-1Q at 31,220, a 1% difference. These averages reflect different test pools, so they should not be read as a direct head-to-head ranking.

Where Each One Wins

Given the data, the RTX PRO 4500 Blackwell wins every shared benchmark. There is no test in the nine recorded comparisons where the GeForce RTX 5080 Mobile comes out on top. This makes the use-case split straightforward: the PRO card is the stronger choice for any workload represented by these tests.

The RTX PRO 4500 Blackwell excels in compute-heavy tasks. The 37% lead in Passmark GPU Compute is the clearest signal. For users running simulations, rendering, or any GPU-accelerated compute workload, the PRO card offers a substantial advantage. Its 50.53 TFLOPS of FP32 performance, compared to 23.04 TFLOPS for the mobile part, supports this; the database shows the PRO card has more than double the raw FP32 throughput.

In graphics workloads, the PRO card also leads, but the margin varies. The 3DMark Steel Nomad test, which is a modern DX12 benchmark, shows a 29.5% gap. The Geekbench Vulkan test shows 23.5%. For gaming or DX12 applications, the PRO card is still clearly ahead, though the 2.5% margin in Passmark DirectX 12 suggests that under certain conditions the mobile part can get much closer.

The RTX 5080 Mobile does not have a single win to point to, but its relative strength appears in the DirectX 12 test where it is nearly tied. If the use case is specifically DirectX 12 gaming at lower power envelopes, the mobile part is not far behind. That is a narrow niche, but it is the only area where the data shows near-parity.

For professional workstation use, the PRO card is the obvious pick. For portable or integrated graphics scenarios, the RTX 5080 Mobile is the only option of the two, given its IGP form factor and 80 W TDP. But in raw performance, the PRO card dominates across every recorded test.

Architecture Differences

Both GPUs are built on the same GB203 chip, using the Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. They share the same transistor count of 45,600 million and the same die size of 378 mm², resulting in an identical transistor density of 120.6M per mm². This means the architectural foundation is the same; the differences come from configuration and power.

The RTX PRO 4500 Blackwell has significantly more execution resources. It packs 10,496 shading units, 328 TMUs, and 112 ROPs. The RTX 5080 Mobile, by comparison, has 7,680 shading units, 240 TMUs, and 96 ROPs. The PRO card also has more RT cores, 82 versus 60, and more tensor cores, 328 versus 240. These differences explain the performance gap: more cores, more texture units, and more render output units all contribute to higher throughput.

Clock speeds also differ substantially. The RTX PRO 4500 Blackwell has a base clock of 1,635 MHz and a boost clock of 2,407 MHz. The RTX 5080 Mobile runs at a 975 MHz base and 1,500 MHz boost. The PRO card's higher clocks, combined with more cores, yield a pixel rate of 269.6 GPixel/s and a texture rate of 789.5 GTexel/s. The mobile part manages 144.0 GPixel/s and 360.0 GTexel/s. That is a significant gap in both fill rates.

Memory is another major differentiator. Both use GDDR7 on a 256-bit bus with 896.0 GB/s of bandwidth, but the RTX PRO 4500 Blackwell has 32 GB of VRAM, double the RTX 5080 Mobile's 16 GB. For large datasets or high-resolution textures, the extra capacity is critical. The memory clock is identical at 1,750 MHz, 28 Gbps effective, so bandwidth is the same.

Power and physical design are fundamentally different. The RTX 5080 Mobile is an integrated graphics package (IGP) with an 80 W TDP and no power connectors. The RTX PRO 4500 Blackwell is a dual-slot card, 267 mm long, 111 mm tall, and 40 mm wide, with a 200 W TDP and a single 16-pin power connector. It requires a 550 W suggested PSU. The mobile part runs entirely off the system's power delivery, while the PRO card needs a dedicated power supply.

Both support PCIe 5.0 x16 and share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ: the mobile part is portable device dependent, while the PRO card has four DisplayPort 2.1b outputs.

The Verdict

The data is unambiguous. The NVIDIA RTX PRO 4500 Blackwell wins all nine shared benchmarks, with margins ranging from 2.5% in Passmark DirectX 12 to 37% in Passmark GPU Compute. It offers more shading units, more RT and tensor cores, higher clocks, double the VRAM, and more than twice the FP32 throughput. For any professional workload, rendering task, or compute-heavy application, the PRO card is the superior choice.

The GeForce RTX 5080 Mobile is not without merit. It is an IGP with an 80 W TDP, meaning it fits into portable devices without dedicated power connectors. Its 16 GB of GDDR7 and 896.0 GB/s bandwidth are respectable, and its DirectX 12 performance is nearly on par with the PRO card, trailing by only 2.5%. For users who need a capable GPU in a laptop or compact integrated system, it is a viable option.

However, the benchmark results indicate that the RTX PRO 4500 Blackwell is the stronger performer in every measured category. The mobile part cannot match the PRO card's compute throughput, texture rate, or pixel rate. The 37% gap in GPU compute and the 29.5% gap in 3DMark Steel Nomad are decisive.

The choice depends on the use case. If the requirement is maximum performance in a workstation or desktop environment with a dedicated power supply, the RTX PRO 4500 Blackwell is the clear pick. If the requirement is a low-power integrated GPU for a portable device, the RTX 5080 Mobile is the only one of the two that fits. The database shows no scenario where the mobile part outperforms the PRO card, so for pure performance, the verdict belongs to the RTX PRO 4500 Blackwell.
