NVIDIA GeForce RTX 4070 vs NVIDIA GeForce RTX 5050 Mobile Comparison

The Verdict

The database comparison between these two NVIDIA GPUs is decisively one-sided. Across both shared benchmark tests, the NVIDIA GeForce RTX 4070 wins every round, and by substantial margins. In the 3DMark Steel Nomad DX12 test, the RTX 4070 scores 3854 against the RTX 5050 Mobile's 2365, a delta of -38.6% from the perspective of the mobile part. In Geekbench OpenCL, the RTX 4070 posts 154858 versus 84171, a difference of -45.6%. The recorded data shows the RTX 4070 ahead by more than a third in one test and nearly half in the other.

The RTX 5050 Mobile does hold a higher percentile ranking against all GPUs in the database at 83, compared to the RTX 4070's 81. This is curious given the head-to-head results, and it suggests that the mobile part's average benchmark score, which sits at 43268, benefits from a broader set of tests beyond these two. The RTX 4070's average is 37648. The RTX 5050 Mobile's nearest rivals include the RTX 4070 SUPER (avg 43223, delta 0.1%), the RTX 4090 Mobile (avg 43667, delta -0.9%), and the Quadro M6000 24 GB (avg 43262, delta 0%). The RTX 4070's rivals are older or lower-tier parts like the Tesla P4 (avg 37628, delta 0.1%) and RX Vega 56 (avg 37507, delta 0.4%). So while the RTX 4070 dominates the direct comparisons, the RTX 5050 Mobile's overall standing in the database is stronger relative to all GPUs. The verdict: pick the RTX 4070 for raw performance in these workloads, but understand that the RTX 5050 Mobile's aggregate profile places it in a different performance class overall.

Architecture Differences

The two GPUs represent different generations of NVIDIA design. The RTX 5050 Mobile is built on the Blackwell 2.0 architecture with the GB207 chip, while the RTX 4070 uses the Ada Lovelace architecture with the AD104 chip. Both are fabricated by TSMC on a 5 nm process, but the transistor counts diverge sharply. The RTX 5050 Mobile packs 16,900 million transistors on a 149 mm² die, giving a transistor density of 113.4M per mm². The RTX 4070 carries 35,800 million transistors on a 294 mm² die, with a density of 121.8M per mm². The RTX 4070 is physically larger and denser, which aligns with its higher performance.

The memory subsystems are also fundamentally different. The RTX 5050 Mobile uses 8 GB of GDDR7 on a 128-bit bus, yielding 384.0 GB/s of bandwidth. The RTX 4070 uses 12 GB of GDDR6X on a 192-bit bus, with 504.2 GB/s of bandwidth. The RTX 4070 has more memory, a wider bus, and higher bandwidth. Clock speeds tell a similar story: the RTX 5050 Mobile runs at 1020 MHz base and 1500 MHz boost, with memory at 1500 MHz (24 Gbps effective). The RTX 4070 runs at 1920 MHz base and 2475 MHz boost, with memory at 1313 MHz (21 Gbps effective). The RTX 4070's core clocks are significantly higher, though its memory clock is lower in raw MHz, the effective rate and bus width compensate.

The compute resources are lopsided. The RTX 5050 Mobile has 2560 shading units, 80 TMUs, 32 ROPs, 20 RT cores, and 80 tensor cores. The RTX 4070 has 5888 shading units, 184 TMUs, 64 ROPs, 46 RT cores, and 184 tensor cores. This translates to a pixel rate of 48.00 GPixel/s and texture rate of 120.0 GTexel/s for the mobile part, versus 158.4 GPixel/s and 455.4 GTexel/s for the RTX 4070. FP32 throughput is 7.680 TFLOPS for the RTX 5050 Mobile and 29.15 TFLOPS for the RTX 4070. The RTX 4070 is roughly four times faster in raw FP32. The RTX 5050 Mobile does have a newer PCIe interface (5.0 x16) versus the RTX 4070's 4.0 x16, and it is an integrated form factor (IGP) with no power connectors, while the RTX 4070 is a dual-slot card requiring a 16-pin connector and a 550 W suggested PSU.

Head-to-Head Benchmarks

The two shared tests in the database show a clear pattern of RTX 4070 dominance. In 3DMark Steel Nomad DX12, the RTX 4070 scores 3854 while the RTX 5050 Mobile scores 2365. The delta is -38.6%, meaning the mobile part trails by more than a third. This is a large gap in a modern DX12 workload, and it reflects the differences in shading units, memory bandwidth, and clock speeds. The RTX 5050 Mobile's 7.680 TFLOPS FP32 is simply not competitive with the RTX 4070's 29.15 TFLOPS in this scenario.

In Geekbench OpenCL, the gap widens further. The RTX 4070 scores 154858 against the RTX 5050 Mobile's 84171, a delta of -45.6%. This test stresses general compute, and the RTX 4070's 5888 shading units and 184 tensor cores provide a massive advantage. The RTX 5050 Mobile's 2560 shading units and 80 tensor cores are less than half of the RTX 4070's counts. The memory bandwidth difference, 384.0 GB/s versus 504.2 GB/s, also plays a role in OpenCL workloads that move large data sets.

The RTX 4070 wins both tests, and the wins are not marginal. A -38.6% and -45.6% delta means the RTX 4070 is roughly 1.6 to 1.8 times faster in these workloads. The RTX 5050 Mobile does have additional benchmark data in the database (its Geekbench OpenCL score of 84171 and 3DMark score of 2365 are the only two listed), while the RTX 4070 has a broader suite including Passmark tests (DirectX 9, 10, 11, 12, G2D, G3D, and GPU compute) and Vulkan, but those are not directly comparable to the mobile part's results. The head-to-head data is limited to these two tests, and the RTX 4070 wins both.

Where Each One Wins

The RTX 4070 wins every head-to-head benchmark in the database. It is the clear choice for any workload measured by 3DMark Steel Nomad DX12 or Geekbench OpenCL. The data shows a 38.6% advantage in the DX12 test and a 45.6% advantage in OpenCL. This makes the RTX 4070 the pick for users prioritizing raw compute throughput, high-resolution rendering, or any application that scales with shading units, memory bandwidth, and FP32 performance. Its 12 GB memory and 504.2 GB/s bandwidth also make it better suited for large textures or data-heavy compute tasks.

The RTX 5050 Mobile, despite losing both direct tests, holds a higher percentile rank (83 versus 81) and a higher average benchmark score (43268 versus 37648). This suggests that in the broader database context, the mobile part performs better relative to all GPUs than the RTX 4070 does. The RTX 5050 Mobile's nearest rivals include the RTX 4070 SUPER and RTX 4090 Mobile, which are high-end parts, while the RTX 4070's rivals are older cards like the Tesla P4 and RX Vega 56. The mobile part's wins are in aggregate scoring, not in direct comparison. It also has advantages in power efficiency: a 50 W TDP versus 200 W, and an integrated form factor with no power connectors, making it suitable for thin laptops where the RTX 4070's dual-slot design and 550 W PSU requirement are not feasible.

For use cases, the RTX 4070 wins in desktop performance scenarios where power and space are not constraints. The RTX 5050 Mobile wins in portability and efficiency scenarios, and its database profile suggests it punches above its weight in a wider range of tests. If the goal is maximum performance in these two specific benchmarks, the RTX 4070 is the only choice. If the goal is a balanced mobile GPU that outperforms its direct rivals in the database, the RTX 5050 Mobile's aggregate score and percentile rank make it a compelling option despite the head-to-head losses.
