The RTX 5070 Ti Mobile has 5888 shading units, 184 TMUs, and 80 ROPs, with 46 ray tracing cores and 184 tensor cores. The desktop workstation card has roughly 78% more shading units than the mobile part.

Clock speeds differ dramatically. The RTX PRO 4500 Blackwell runs at a base clock of 1635 MHz and boosts to 2407 MHz. The RTX 5070 Ti Mobile runs at a much lower 847 MHz base and 1447 MHz boost, reflecting its mobile power envelope. The desktop card's higher clocks and larger chip yield a peak FP32 throughput of 50.53 TFLOPS, nearly triple the 17.04 TFLOPS of the mobile GPU.

Memory subsystems are also different. The RTX PRO 4500 Blackwell has 32 GB of GDDR7 on a 256-bit bus, producing 896.0 GB/s of bandwidth. The RTX 5070 Ti Mobile has 12 GB of GDDR7 on a 192-bit bus, yielding 672.0 GB/s. Both run memory at 1750 MHz with 28 Gbps effective speed.

Physical design separates the two clearly. The RTX 5070 Ti Mobile is an integrated graphics processor with no slot width, no power connectors, and display outputs described as portable device dependent. The RTX PRO 4500 Blackwell is a dual-slot card measuring 267 mm in length, 111 mm in height, and 40 mm in width, with four DisplayPort 2.1b outputs. Both use a PCIe 5.0 x16 bus interface and support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data describes two GPUs with opposing design goals. The RTX 5070 Ti Mobile is built for mobility, with a 60 W TDP, no external power connectors, and a compact integrated design. The RTX PRO 4500 Blackwell is a full-size workstation card drawing 200 W and requiring a 550 W power supply.

Benchmark results show the RTX PRO 4500 Blackwell winning every single head-to-head test in the database. It leads by 37.2% in Geekbench Vulkan, by 28% in Passmark G3D, and by 47.5% in Passmark GPU Compute. The largest margin is in compute workloads, which aligns with its workstation positioning.

However, the RTX 5070 Ti Mobile has the higher average benchmark score (35435 versus 31532) and the higher percentile ranking (80th versus 76th). This is because the mobile GPU's benchmark results include a Geekbench OpenCL score of 143870, which contributes to its average, while the RTX PRO 4500's average is weighted across its recorded tests.

The choice depends on the platform. For a laptop or portable system where power draw and physical size matter, the RTX 5070 Ti Mobile is the only viable option given its integrated design. For a desktop workstation requiring maximum compute throughput, the RTX PRO 4500 Blackwell delivers substantially higher raw performance across every measured workload, at the cost of 200 W power draw and a dual-slot footprint.

Users who need 32 GB of memory, the higher FP32 throughput of 50.53 TFLOPS, and the compute lead should select the RTX PRO 4500 Blackwell. Users constrained by mobile form factors should choose the RTX 5070 Ti Mobile, which offers the higher aggregate benchmark standing despite losing every direct comparison.

The largest victory is in Passmark GPU Compute, where it scores 19255 against the RTX 5070 Ti Mobile's 10101, a 47.5% advantage. This compute lead reflects the workstation card's larger tensor core count and higher clock speeds.

In Geekbench Vulkan, the RTX PRO 4500 scores 221768 against 139213, a 37.2% lead. This is the second-largest margin. The workstation card also wins the older DirectX tests: Passmark DirectX 9 shows 397 versus 259 (34.8% ahead), Passmark DirectX 10 shows 204 versus 151 (26% ahead), and Passmark DirectX 11 shows 320 versus 237 (25.9% ahead).

The Passmark DirectX 12 result is the closest contest. The RTX PRO 4500 scores 119 versus 102, a 14.3% margin. This narrower gap suggests that the newer API reduces some of the architectural advantage, though the workstation card still comes out ahead.

In Passmark G3D, the RTX PRO 4500 scores 33360 against 24004, a 28% lead. Passmark G2D shows 1336 versus 981, a 26.6% lead. Every test in the database favors the RTX PRO 4500 Blackwell.

The RTX 5070 Ti Mobile's higher average benchmark score of 35435 comes from its Geekbench OpenCL result of 143870, a test not recorded for the RTX PRO 4500. When only the shared tests are considered, the RTX PRO 4500 is ahead in every case. The mobile GPU also has a higher percentile ranking (80th versus 76th), which reflects how its recorded scores position it relative to the full GPU database.

Where Each One Wins

The RTX PRO 4500 Blackwell wins in every direct benchmark comparison, so the use-case split is defined by workload type and platform constraints rather than test outcomes.

For compute-heavy workloads, the RTX PRO 4500 Blackwell is clearly superior. Its 47.5% lead in Passmark GPU Compute and 37.2% lead in Geekbench Vulkan indicate strong performance in tasks that leverage parallel processing, ray tracing, and tensor operations. The 32 GB memory capacity and 896.0 GB/s bandwidth support large datasets and high-resolution textures. The 50.53 TFLOPS FP32 throughput positions it for professional rendering, simulation, and AI inference tasks.

For legacy DirectX workloads, the RTX PRO 4500 also leads, with margins ranging from 14.3% in DirectX 12 to 34.8% in DirectX 9. This consistency across API generations suggests the workstation card's higher raw throughput translates across both modern and older code paths.

The RTX 5070 Ti Mobile wins in the aggregate benchmark standing. Its average score of 35435 exceeds the RTX PRO 4500's 31532, and its 80th percentile ranking beats the 76th percentile of the workstation card. This is notable because the mobile GPU achieves this with a 60 W power budget and no external power connectors, compared to the 200 W TDP of the desktop card.

The mobile GPU is the appropriate choice for portable systems. Its integrated design, lack of power connectors, and low 60 W TDP make it suitable for laptops where space and thermal limits are strict. The RTX PRO 4500 Blackwell requires a dual-slot chassis, a 550 W power supply, and a 267 mm card length, which rules out compact or mobile builds.

For users prioritizing raw performance in a desktop workstation, the RTX PRO 4500 Blackwell wins every measured workload. For users prioritizing portability and aggregate benchmark standing, the RTX 5070 Ti Mobile holds the advantage. The 12 GB memory capacity of the mobile GPU may suffice for gaming and lighter workloads, while the 32 GB capacity of the workstation card addresses professional memory-intensive applications.
