NVIDIA GeForce RTX 4080 Mobile vs NVIDIA GeForce RTX 5050 Mobile Comparison

The NVIDIA GeForce RTX 5050 Mobile and NVIDIA GeForce RTX 4080 Mobile represent two distinct generations of laptop graphics, with the 5050 being the newer, more power-efficient entry point and the 4080 being the older, higher-tier performer. Benchmark data shows a clear performance hierarchy, but the newer part offers architectural advancements and a significantly lower power draw, making the choice dependent on whether raw speed or efficiency is the priority.

Where Each One Wins

The RTX 4080 Mobile is the clear winner in raw computational performance. In the single shared benchmark, it outperforms the RTX 5050 Mobile by a wide margin, and its broader suite of benchmark scores indicates strength across various DirectX versions and compute workloads.

The RTX 5050 Mobile’s advantage lies in its efficiency and modern feature set. It consumes less than half the power of the RTX 4080 Mobile (50 W vs 110 W), making it more suitable for thin-and-light laptops where thermal headroom is limited. It also supports PCIe 5.0, which is a generation ahead of the 4080 Mobile’s PCIe 4.0 interface. For users who prioritize battery life and portability over maximum frames per second, the 5050 Mobile is the more sensible choice.

The RTX 4080 Mobile dominates in memory capacity and bandwidth, offering 12 GB of VRAM compared to the 5050 Mobile’s 8 GB, and a 432.0 GB/s bandwidth versus 384.0 GB/s. This makes the 4080 Mobile better suited for tasks that require large textures or datasets, such as high-resolution gaming or certain creative workloads.

Head-to-Head Benchmarks

The only direct head-to-head benchmark available is Geekbench OpenCL. In this test, the RTX 4080 Mobile scores 159575, while the RTX 5050 Mobile scores 84171. The delta is -47.3%, meaning the RTX 4080 Mobile is roughly 89.5% faster than the RTX 5050 Mobile in this specific test. This is a substantial gap, reflecting the 4080 Mobile’s much larger shader count (7424 vs 2560) and higher clock speeds.

Beyond the shared test, the RTX 4080 Mobile’s individual benchmark results show consistent performance across different APIs. Its Passmark scores include 24926 in G3D, 11191 in GPU Compute, and 929 in G2D. It also scores 145807 in Geekbench Vulkan. These numbers suggest the 4080 Mobile is a well-rounded performer across both compute and graphics tasks.

The RTX 5050 Mobile has fewer recorded benchmarks, with only Geekbench OpenCL and 3DMark Steel Nomad (2365) listed. Its OpenCL score is notably lower than the 4080 Mobile, but the 5050 Mobile’s average benchmark score of 43268 is higher than the 4080 Mobile’s 38135, likely due to different weighting of the tests included in each average.

Specification Differences

The RTX 4080 Mobile has a significantly larger GPU: 35,800 million transistors on a 294 mm² die, compared to the RTX 5050 Mobile’s 16,900 million transistors on a 149 mm² die. This corresponds to a much higher core count for the 4080 Mobile, which has 7424 shading units, 232 TMUs, and 80 ROPs, versus the 5050 Mobile’s 2560 shading units, 80 TMUs, and 32 ROPs.

Clock speeds differ, with the RTX 4080 Mobile running at a base of 1290 MHz and boost of 1665 MHz, while the RTX 5050 Mobile runs at 1020 MHz base and 1500 MHz boost. Memory also differs: the 4080 Mobile uses 12 GB of GDDR6 at 2250 MHz (18 Gbps effective) on a 192-bit bus, while the 5050 Mobile uses 8 GB of GDDR7 at 1500 MHz (24 Gbps effective) on a 128-bit bus.

The RTX 5050 Mobile has a lower TDP of 50 W, compared to the 4080 Mobile’s 110 W. The bus interface also differs, with the 5050 Mobile supporting PCIe 5.0 x16 and the 4080 Mobile using PCIe 4.0 x16. Both are IGP slot width and have no power connectors.

Architecture Differences

The RTX 5050 Mobile is built on the Blackwell 2.0 architecture using the GB207 chip, while the RTX 4080 Mobile uses the Ada Lovelace architecture with the AD104 chip. Both are fabricated on a 5 nm process at TSMC, but the 4080 Mobile has a higher transistor density at 121.8M / mm² versus 113.4M / mm² for the 5050 Mobile.

The RTX 4080 Mobile has more ray tracing cores (58 vs 20) and tensor cores (232 vs 80), reflecting its higher compute capability. However, the RTX 5050 Mobile uses faster GDDR7 memory, which offers a higher effective speed of 24 Gbps versus 18 Gbps for the GDDR6 in the 4080 Mobile, despite the latter having a wider bus.

Both GPUs support the same API levels: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5050 Mobile is the successor to the GeForce 40 Mobile series, which includes the RTX 4080 Mobile, indicating a generational leap in architecture.

The Verdict

The data clearly shows the RTX 4080 Mobile is the superior performer. In the only direct comparison, it leads by 47.3% in OpenCL, and its larger core count, higher clock speeds, and greater memory bandwidth all point to significantly better frame rates and compute throughput. For gaming at high settings or running demanding creative applications, the RTX 4080 Mobile is the stronger choice.

However, the RTX 5050 Mobile is not without merit. Its lower TDP of 50 W makes it far more efficient, and it supports the newer PCIe 5.0 standard. For users who need a capable GPU for lighter gaming or productivity tasks in a thin-and-light laptop, the 5050 Mobile offers a modern feature set with less power draw. The choice ultimately depends on whether raw performance or efficiency is the primary concern.
