NVIDIA GeForce RTX 4070 Mobile vs NVIDIA RTX PRO 4500 Blackwell Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep for the NVIDIA RTX PRO 4500 Blackwell across all eight shared benchmark tests, with the GeForce RTX 4070 Mobile failing to secure a single win. The most decisive margin appears in the Passmark GPU compute test, where the RTX PRO 4500 Blackwell scores 19,255 against 8,399, a 129.3% advantage. This result reflects the workstation card's far larger shading and tensor core count, which directly impacts raw computational throughput.

In the Geekbench Vulkan test, the gap is similarly pronounced. The RTX PRO 4500 Blackwell posts 221,768 points versus 108,367 for the RTX 4070 Mobile, a 104.6% lead. This benchmark stresses asynchronous compute and graphics workloads, where the Blackwell architecture's 82 RT cores and 10,496 shading units provide a substantial advantage over the mobile chip's 36 RT cores and 4,608 shading units.

The DirectX legacy tests show consistent, though less extreme, margins. Passmark DirectX 11 yields 320 for the RTX PRO 4500 Blackwell against 179 for the RTX 4070 Mobile, a 78.8% delta. DirectX 9 shows a 78% advantage (397 vs 223), while DirectX 10 records a 75.9% lead (204 vs 116). These older API tests tend to be more driver- and clock-sensitive, yet the desktop workstation card still maintains a commanding edge.

The DirectX 12 result narrows the gap somewhat, with the RTX PRO 4500 Blackwell scoring 119 versus 85, a 40% delta. This suggests that the mobile GPU's architecture handles modern API overhead more efficiently relative to its older-API performance, but it remains firmly behind. The Passmark G2D test, which measures 2D graphics and desktop composition performance, shows a 75.1% lead for the RTX PRO 4500 Blackwell (1,336 vs 763), reflecting the benefits of its higher pixel fill rate and dual-slot cooling design.

The Passmark G3D score, a composite of multiple 3D rendering workloads, places the RTX PRO 4500 Blackwell at 33,360 versus 19,587 for the RTX 4070 Mobile, a 70.3% delta. This aligns with the average benchmark scores: the RTX PRO 4500 Blackwell averages 31,532 across all recorded tests, while the RTX 4070 Mobile averages 27,435. The difference in average scores is 15%, but the head-to-head deltas are larger because the shared tests skew toward workloads where the workstation card's memory bandwidth and compute resources matter most.

The Verdict

The data points to a clear hierarchy: the NVIDIA RTX PRO 4500 Blackwell is the superior performer in every recorded benchmark shared with the GeForce RTX 4070 Mobile. Its 129.3% lead in compute, 104.6% lead in Vulkan, and 70.3% lead in G3D make it the obvious choice for workloads that prioritize raw throughput, large data sets, or sustained rendering. The 76th percentile ranking versus 73rd for the mobile card confirms its position higher in the overall GPU distribution.

However, context matters. The RTX 4070 Mobile is an integrated graphics processor designed for laptops, with a 115 W TDP and no separate power connector. The RTX PRO 4500 Blackwell is a 200 W dual-slot desktop card requiring a 550 W suggested power supply and a 16-pin connector. For portable systems, the RTX 4070 Mobile remains the only viable option of the two, despite its lower scores. For desktop workstations where power and space are available, the RTX PRO 4500 Blackwell delivers nearly double the compute performance and 3.5 times the memory bandwidth.

Users prioritizing maximum benchmark scores should select the RTX PRO 4500 Blackwell without hesitation. Users constrained by laptop form factors have no choice but the RTX 4070 Mobile, and its 73rd percentile ranking still places it above a majority of all GPUs. The nearest rivals for the RTX PRO 4500 Blackwell include the NVIDIA TITAN RTX with an average score of 31,676 (0.5% higher) and the Intel Arc Pro A30M at 31,894 (1.1% higher), indicating that the workstation card sits in a competitive mid-to-high tier. The RTX 4070 Mobile's nearest rival, the AMD Radeon RX 6700 XT, matches it exactly at 27,425 average score, placing the mobile chip in a crowded performance band.

Specification Differences

The two cards differ across nearly every core specification. The RTX PRO 4500 Blackwell uses the GB203 chip with 45,600 million transistors on a 378 mm² die, while the RTX 4070 Mobile uses the AD106 chip with 22,900 million transistors on a 188 mm² die. Transistor density is nearly identical (120.6M per mm² versus 121.8M per mm²), but the physical size difference is stark.

Clock speeds diverge significantly. The RTX PRO 4500 Blackwell runs at a base of 1635 MHz and boosts to 2407 MHz. The RTX 4070 Mobile runs at 1395 MHz base and 1695 MHz boost. Memory clocks also differ: the workstation card uses 1750 MHz with 28 Gbps effective, while the mobile card uses 2000 MHz with 16 Gbps effective. The memory subsystem differs completely: 32 GB of GDDR7 on a 256-bit bus versus 8 GB of GDDR6 on a 128-bit bus. Bandwidth is 896.0 GB/s versus 256.0 GB/s.

Core counts show a 2.3x advantage for the workstation card. The RTX PRO 4500 Blackwell has 10,496 shading units, 328 TMUs, and 112 ROPs. The RTX 4070 Mobile has 4,608 shading units, 144 TMUs, and 48 ROPs. RT cores number 82 versus 36, and tensor cores number 328 versus 144. Pixel rate is 269.6 GPixel/s versus 81.36 GPixel/s, and texture rate is 789.5 GTexel/s versus 244.1 GTexel/s. FP32 compute is 50.53 TFLOPS versus 15.62 TFLOPS, with FP16 also at 50.53 TFLOPS versus 15.62 TFLOPS.

Power and physical specifications differ as expected. The RTX PRO 4500 Blackwell has a 200 W TDP, dual-slot width, a 16-pin power connector, and a 550 W suggested PSU. The RTX 4070 Mobile has a 115 W TDP, IGP slot width, and no power connector. The bus interface is PCIe 5.0 x16 for the workstation card versus PCIe 4.0 x8 for the mobile card. Display outputs are 4x DisplayPort 2.1b for the desktop card, while the mobile card's outputs are portable device dependent. The workstation card has dimensions of 267 mm length, 111 mm height, and 40 mm width; the mobile card has no recorded dimensions.

Architecture Differences

The architectural split is generational. The RTX PRO 4500 Blackwell uses the Blackwell 2.0 architecture, while the RTX 4070 Mobile uses Ada Lovelace. Both are built on a 5 nm TSMC process, but the design philosophies differ. Blackwell 2.0 represents a newer generation, as indicated by the release dates: the RTX PRO 4500 Blackwell launched on 2025-03-17, while the RTX 4070 Mobile launched on 2023-01-02. The predecessor to the workstation card is Workstation Ada, while the predecessor to the mobile card is GeForce 30 Mobile. The mobile card has a successor, GeForce 50 Mobile, but the workstation card has none recorded.

The transistor count difference (45,600 million versus 22,900 million) reflects not just die size but architectural complexity. The Blackwell 2.0 architecture doubles the RT core count (82 versus 36) and more than doubles tensor cores (328 versus 144). The RTX PRO 4500 Blackwell also supports the same APIs as the mobile card: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both achieve identical API support despite the architectural differences.

The memory type marks a generational shift: GDDR7 on the workstation card versus GDDR6 on the mobile card. This, combined with the wider 256-bit bus, explains the 3.5x bandwidth advantage. The mobile card's smaller 128-bit bus and 8 GB capacity are typical for laptop implementations, where power and thermal limits constrain memory design. The workstation card's 32 GB capacity and 896.0 GB/s bandwidth are designed for large datasets and multi-application workflows.

The transistor density figures are nearly identical (120.6M per mm² versus 121.8M per mm²), suggesting both chips use a similar process maturity. The performance difference therefore comes from the larger die, higher clock speeds, and more generous power budget of the desktop workstation card. The RTX PRO 4500 Blackwell's boost clock of 2407 MHz is 712 MHz higher than the mobile card's boost of 1695 MHz, a 42% clock advantage that compounds with the core count difference. The architecture differences are not merely cosmetic: they translate directly into the benchmark deltas observed across all eight tests.
