The NVIDIA GeForce RTX 4050 Mobile and the NVIDIA GeForce RTX 5070 Ti Mobile represent two distinct generations of laptop GPUs, with the latter delivering a decisive performance advantage across every recorded benchmark. The data shows a clean sweep, with the RTX 5070 Ti Mobile winning all nine head-to-head comparisons.

Head-to-Head Benchmarks

The most significant gap appears in compute-oriented workloads. In Geekbench OpenCL, the RTX 5070 Ti Mobile scores 143870 against the RTX 4050 Mobile's 74748, a 48% delta in favor of the newer chip. Vulkan results follow a similar pattern, with the RTX 5070 Ti Mobile at 139213 versus 75235, a 46% advantage. These results indicate that the RTX 5070 Ti Mobile is substantially stronger in general-purpose GPU compute tasks.

DirectX 12 performance, which often reflects modern gaming loads, shows the RTX 5070 Ti Mobile at 102 versus the RTX 4050 Mobile's 61, a 40.2% lead. The gap narrows slightly in DirectX 11, where the RTX 5070 Ti Mobile scores 237 against 130, a 45.1% difference. Older API workloads compress the delta further: DirectX 9 sees the RTX 5070 Ti Mobile at 259 versus 184, a 29% lead, while DirectX 10 shows 151 against 79, a 47.7% gap.

The Passmark G3D score, a broad gaming metric, places the RTX 5070 Ti Mobile at 24004 versus 14423 for the RTX 4050 Mobile, a 39.9% advantage. The compute-specific Passmark GPU Compute test delivers 10101 for the RTX 5070 Ti Mobile against 5947, a 41.1% lead. Even the 2D graphics test shows the newer part ahead, with 981 versus 633, a 35.5% difference. In every single test, the RTX 5070 Ti Mobile holds a lead ranging from 29% to 48%.

Architecture Differences

The two GPUs are built on different architectures. The RTX 4050 Mobile uses Ada Lovelace with the AD107 chip, while the RTX 5070 Ti Mobile employs Blackwell 2.0 with the GB205 chip. Both are fabricated on a 5 nm process at TSMC, but the transistor counts diverge sharply. The RTX 4050 Mobile packs 18,900 million transistors on a 159 mm² die, yielding a density of 118.9M per mm². The RTX 5070 Ti Mobile scales up to 31,100 million transistors on a 263 mm² die, with a nearly identical density of 118.3M per mm².

Memory configuration presents another major split. The RTX 4050 Mobile uses 6 GB of GDDR6 on a 96-bit bus, delivering 192.0 GB/s of bandwidth. The RTX 5070 Ti Mobile doubles the capacity to 12 GB of GDDR7 on a 192-bit bus, quadrupling bandwidth to 672.0 GB/s. This bandwidth advantage is critical for high-resolution textures and compute-heavy workloads.

Compute resources also differ substantially. The RTX 4050 Mobile carries 2560 shading units, 80 TMUs, 48 ROPs, 20 RT cores, and 80 tensor cores. The RTX 5070 Ti Mobile more than doubles shading units to 5888, with 184 TMUs, 80 ROPs, 46 RT cores, and 184 tensor cores. Pixel rate climbs from 84.24 GPixel/s to 115.8 GPixel/s, while texture rate jumps from 140.4 GTexel/s to 266.2 GTexel/s. FP32 throughput rises from 8.986 TFLOPS to 17.04 TFLOPS, with FP16 at the same 1:1 ratio for both.

Clock speeds tell a different story. The RTX 4050 Mobile runs a base clock of 1455 MHz and a boost of 1755 MHz. The RTX 5070 Ti Mobile operates at a lower base of 847 MHz and a boost of 1447 MHz, but its architectural advances and memory improvements overcome the clock deficit. The RTX 5070 Ti Mobile also uses a newer PCIe interface, PCIe 5.0 x16, versus PCIe 4.0 x8 on the RTX 4050 Mobile. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The RTX 5070 Ti Mobile carries a 60 W TDP against 50 W for the RTX 4050 Mobile. Both are IGP-class parts with no power connectors and portable-device-dependent display outputs. The RTX 4050 Mobile released in January 2023, while the RTX 5070 Ti Mobile arrived in February 2025, with the latter succeeding the GeForce 40 Mobile generation.

Where Each One Wins

The RTX 5070 Ti Mobile wins every recorded benchmark category. In compute-heavy tasks like Geekbench OpenCL and Vulkan, its lead is the largest, at 48% and 46% respectively. This makes it the clear choice for workloads involving GPU compute, simulation, or general-purpose parallel processing. The Passmark GPU Compute score reinforces this, with a 41.1% advantage.

For gaming, the RTX 5070 Ti Mobile leads in every DirectX version. The smallest gap appears in DirectX 9 at 29%, while DirectX 10 and 11 show leads above 45%. DirectX 12, the most relevant modern API, shows a 40.2% lead. The Passmark G3D score confirms the overall gaming superiority, with a 39.9% edge. The RTX 4050 Mobile, while slower, still records competitive absolute scores for its class, particularly in DirectX 9 where it reaches 184 versus the newer part's 259.

The RTX 4050 Mobile's only advantages are indirect. Its lower TDP of 50 W suggests lower power draw, and its smaller die size of 159 mm² implies lower manufacturing complexity. Its higher clock speeds, at 1755 MHz boost versus 1447 MHz, indicate a more aggressive clock profile per watt. However, none of these translate into a benchmark win.
