NVIDIA GeForce RTX 5070 Mobile vs NVIDIA RTX 4500 Ada Generation Comparison

The Verdict

The recorded data separates these two NVIDIA parts clearly by workload class. The NVIDIA RTX 4500 Ada Generation wins both head-to-head benchmark comparisons, with a 24% advantage in Geekbench OpenCL and a 31.8% advantage in Geekbench Vulkan. Its average benchmark score of 166,094 places it in the 97th percentile of all GPUs in the database, while the GeForce RTX 5070 Mobile averages 29,928 and sits in the 75th percentile.

The RTX 5070 Mobile is a 50 W integrated graphics solution for portable devices, built on the Blackwell 2.0 architecture with the GB206 chip. The RTX 4500 Ada Generation is a dual-slot workstation card with a 210 W power draw, using the Ada Lovelace architecture with the AD103 chip. The data indicates the RTX 4500 Ada Generation is for compute-heavy professional workloads where maximum throughput matters, while the RTX 5070 Mobile targets thin-and-light systems where power limits dominate.

For users constrained by portable device thermal and power envelopes, the RTX 5070 Mobile is the only viable choice among these two, as its 50 W TDP and IGP slot width fit portable designs. For anyone with desktop workstation space and power headroom, the RTX 4500 Ada Generation delivers substantially higher raw performance in every recorded benchmark, along with 24 GB of memory versus 8 GB.

Where Each One Wins

The RTX 4500 Ada Generation wins both recorded head-to-head benchmarks. In Geekbench OpenCL, it scores 160,786 against 122,238 for the RTX 5070 Mobile, a 24% margin. In Geekbench Vulkan, the gap widens to 31.8%, with 171,401 versus 116,960. The workstation card also holds a commanding lead in raw compute specifications: 39.63 TFLOPS FP32 against 13.13 TFLOPS, 619.2 GTexel/s texture rate versus 205.2 GTexel/s, and 206.4 GPixel/s pixel rate versus 68.40 GPixel/s.

The RTX 5070 Mobile has no benchmark wins in the head-to-head data. However, its advantage lies in physical integration. The database lists it as an IGP with no power connectors and no suggested PSU, whereas the RTX 4500 Ada Generation is dual-slot, 245 mm long, 112 mm tall, and requires a 550 W suggested PSU. The mobile part also uses PCIe 5.0 x16, a newer bus interface than the workstation card's PCIe 4.0 x16.

The RTX 5070 Mobile belongs in portable devices where the display outputs are device-dependent. The RTX 4500 Ada Generation provides four DisplayPort 1.4a outputs, indicating a fixed workstation configuration for multi-monitor setups.

Architecture Differences

The two GPUs come from different NVIDIA architectures and chip generations. The RTX 5070 Mobile uses the GB206 chip on Blackwell 2.0, fabricated on a 5 nm process at TSMC with 21,900 million transistors on a 181 mm² die. The RTX 4500 Ada Generation uses the AD103 chip on Ada Lovelace, also 5 nm at TSMC, but with 45,900 million transistors on a 379 mm² die. Transistor density is nearly identical: 121.0 million per mm² for the mobile chip and 121.1 million per mm² for the workstation chip.

The compute resources differ substantially. The RTX 5070 Mobile has 4,608 shading units, 144 texture mapping units, 48 raster output units, 36 ray tracing cores, and 144 tensor cores. The RTX 4500 Ada Generation has 7,680 shading units, 240 TMUs, 80 ROPs, 60 ray tracing cores, and 240 tensor cores. The workstation card has 66.7% more shading units, 66.7% more TMUs, 66.7% more ROPs, 66.7% more ray tracing cores, and 66.7% more tensor cores.

Clock behavior also diverges. The RTX 5070 Mobile runs at a 907 MHz base and 1425 MHz boost, while the RTX 4500 Ada Generation runs at 2070 MHz base and 2580 MHz boost. The workstation card's higher clocks compound its larger shader count, producing the large FP32 and texture rate gaps.

Memory configurations are entirely different generations. The RTX 5070 Mobile uses 8 GB of GDDR7 on a 128-bit bus with 384.0 GB/s bandwidth, running at 1500 MHz with 24 Gbps effective. The RTX 4500 Ada Generation uses 24 GB of GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth, running at 2250 MHz with 18 Gbps effective. The workstation card offers 3 times the capacity and 12.5% more bandwidth despite older memory technology.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5070 Mobile was released on 2025-04-14, succeeding GeForce 40 Mobile. The RTX 4500 Ada Generation was released on 2023-08-08, succeeding Workstation Ampere and succeeded by Blackwell PRO W.

Head-to-Head Benchmarks

The head-to-head data contains only two benchmark comparisons, and the RTX 4500 Ada Generation wins both. In Geekbench OpenCL, the workstation card scores 160,786 against 122,238 for the mobile part, a 24% margin. In Geekbench Vulkan, the RTX 4500 Ada Generation scores 171,401 against 116,960, a 31.8% margin.

The Vulkan gap is the larger of the two, which aligns with the specification differences. The RTX 4500 Ada Generation has 7,680 shading units and 240 tensor cores, while the RTX 5070 Mobile has 4,608 and 144 respectively. The workstation card also boosts to 2580 MHz versus 1425 MHz for the mobile part, so both the shader count and the clock rate favor the workstation card.

The OpenCL result shows a smaller relative gap. This may reflect the different memory architectures: the mobile part uses GDDR7 with 24 Gbps effective speed, while the workstation card uses GDDR6 at 18 Gbps effective. The workstation card still has 432.0 GB/s bandwidth versus 384.0 GB/s, so it remains ahead in memory throughput despite older memory technology.

The RTX 5070 Mobile's nearest rival data provides context for its absolute performance. Its 29,928 average score places it within 1.7% of the Radeon RX 6700 (30,433) and 0.1% of the GeForce RTX 3070 Ti (29,945). The RTX 4500 Ada Generation sits in a different performance class entirely: its 166,094 average is 0.5% ahead of the RTX A5500 (165,217), 0.7% ahead of the Radeon PRO W7800 (164,894), 1.5% behind the Radeon Pro W6900X (168,574), and 2.2% ahead of the NVIDIA A100 PCIe 40 GB (162,504).

The percentile rankings reinforce this separation. The RTX 5070 Mobile sits in the 75th percentile of all GPUs, while the RTX 4500 Ada Generation sits in the 97th percentile. That 22-point percentile gap reflects the substantial compute resource difference between the two parts.

The transistor density is nearly identical (121.0M per mm² versus 121.1M per mm²), indicating both chips come from the same 5 nm TSMC process. The workstation die is 2.1 times larger in area and carries 2.1 times more transistors, which explains the proportional increases in shading units, TMUs, ROPs, ray tracing cores, and tensor cores.

Both parts support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both are listed as Active production status. Neither has a recorded launch MSRP in the database.
