NVIDIA GeForce MX550 vs NVIDIA GeForce RTX 5070 Mobile Comparison

Head-to-Head Benchmarks

The benchmark data presents a decisive picture: the NVIDIA GeForce RTX 5070 Mobile wins both recorded head-to-head tests against the NVIDIA GeForce MX550, and the margins are substantial. In the Geekbench OpenCL test, the RTX 5070 Mobile scores 122,238 points against the MX550’s 20,372 points. That is a delta of 500%, meaning the newer part delivers roughly six times the compute throughput in this API. The Vulkan result is similarly one-sided, though the gap narrows slightly: the RTX 5070 Mobile posts 116,960 points versus 32,469 points for the MX550, a 260.2% advantage. In plain terms, the RTX 5070 Mobile is not just faster; it is in a different performance class altogether.

Looking at the broader average benchmark score, the RTX 5070 Mobile achieves 29,928 across all recorded tests, while the MX550 sits at 26,421. That is a 13.3% overall lead, which is notable given how lopsided the individual Geekbench results are. The discrepancy highlights that the MX550’s average is propped up by its relatively better showing in Vulkan, where it reaches 32,469, while the RTX 5070 Mobile’s Vulkan score of 116,960 is still far ahead but not as dominant as its OpenCL result. The data suggests the MX550 has some architectural strengths in Vulkan workloads, but those strengths are nowhere near enough to close the gap.

The RTX 5070 Mobile also benefits from a wider benchmark suite in the database. It has recorded scores for Passmark DirectX 10, 11, 12, and 9, plus G2D, G3D, and GPU compute tests. The MX550 only has Geekbench OpenCL and Vulkan entries. In the Passmark tests, the RTX 5070 Mobile shows strong D3D performance: 214 in DirectX 9, 192 in DirectX 11, 129 in DirectX 10, and 93 in DirectX 12. Its G3D score is 20,355, and its GPU compute score is 8,279. These figures, while not directly comparable to the MX550 due to missing data, reinforce that the RTX 5070 Mobile is a serious performer across multiple rendering paths.

When placed against its nearest rivals in the database, the RTX 5070 Mobile holds its own remarkably well. It trails the NVIDIA GeForce RTX 3070 Ti by just 0.1% (29,945 vs. 29,928), sits 0.5% above the RTX 2080 Ti (29,783), and is 0.6% behind the AMD Radeon RX 6800 (30,095). The largest gap is a 1.7% deficit to the AMD Radeon RX 6700 (30,433). For a mobile part with a 50 W TDP, being within striking distance of desktop-class GPUs from previous generations is a strong statement. The MX550, by contrast, is essentially level with its nearest rivals: it is 0.1% ahead of the AMD Radeon 860M (26,401), 0.3% ahead of the NVIDIA GeForce RTX 5060 (26,331), 0.5% behind the AMD Radeon RX 5700 XT 50th Anniversary (26,553), and 1% behind the NVIDIA RTX A4000 (26,683). The MX550 is a competent entry-level chip, but the RTX 5070 Mobile is operating in a tier that the MX550 cannot approach.

Where Each One Wins

The RTX 5070 Mobile is the clear choice for any workload that demands raw compute throughput. Its OpenCL score of 122,238 is not just a win; it is a generational leap over the MX550’s 20,372. This makes it suitable for GPU-accelerated tasks such as video encoding, 3D rendering, scientific simulation, and machine learning inference. The Vulkan result, 116,960 vs. 32,469, reinforces that the RTX 5070 Mobile is also the better option for modern gaming, where Vulkan is increasingly the API of choice for high-end titles. With 8 GB of GDDR7 memory and a 384.0 GB/s bandwidth, the RTX 5070 Mobile has the resources to handle large textures and complex scenes. The MX550’s 2 GB GDDR6 frame buffer with 96.00 GB/s bandwidth is a limiting factor in any modern game or professional application.

The MX550 wins in one specific category: power efficiency. Its TDP is 25 W, exactly half of the RTX 5070 Mobile’s 50 W. For ultra-portable laptops where battery life and thermal headroom are paramount, the MX550 is the less demanding component. It also has a higher base clock (1,065 MHz vs. 907 MHz) and a higher boost clock (1,320 MHz vs. 1,425 MHz is actually lower for the MX550, so the boost advantage goes to the RTX 5070 Mobile). However, the MX550’s lower power draw means it can be passively cooled or paired with very small heatsinks, making it viable for thin-and-light designs. Its 72nd percentile ranking shows it is not a weak chip; it is simply aimed at a different market segment.

For users who need a discrete GPU for light photo editing, casual gaming at low settings, or hardware acceleration for video playback, the MX550 remains a functional option. Its Vulkan score of 32,469 is respectable for its class, and its 0.1% lead over the AMD Radeon 860M shows it is competitive within its peer group. But the RTX 5070 Mobile is the winner for anyone who prioritizes performance over power consumption. The database’s wins tally (2 for the RTX 5070 Mobile, 0 for the MX550) leaves no ambiguity in that regard.

Specification Differences

The two GPUs differ in nearly every measurable specification. The RTX 5070 Mobile is built on a 5 nm process node, while the MX550 uses a 12 nm node. The RTX 5070 Mobile packs 21,900 million transistors on a 181 mm² die, giving a transistor density of 121.0M per mm². The MX550 has 4,700 million transistors on a larger 200 mm² die, resulting in a density of just 23.5M per mm². This density difference explains why the RTX 5070 Mobile can offer so much more compute in a similar physical footprint.

Memory configurations are starkly different. The RTX 5070 Mobile has 8 GB of GDDR7 on a 128-bit bus, delivering 384.0 GB/s of bandwidth. The MX550 has 2 GB of GDDR6 on a 64-bit bus, yielding 96.00 GB/s. The RTX 5070 Mobile’s memory clock is 1,500 MHz with 24 Gbps effective, while the MX550 runs at 1,500 MHz with 12 Gbps effective. The RTX 5070 Mobile has 4,608 shading units, 144 texture mapping units, and 48 ROPs. The MX550 has 1,024 shading units, 32 TMUs, and 16 ROPs. The RTX 5070 Mobile also features 36 RT cores and 144 tensor cores; the MX550 has none of either.

Pixel and texture rates reflect the compute disparity. The RTX 5070 Mobile achieves 68.40 GPixel/s and 205.2 GTexel/s, versus 21.12 GPixel/s and 42.24 GTexel/s for the MX550. Floating-point performance is similarly lopsided: the RTX 5070 Mobile delivers 13.13 TFLOPS in both FP32 and FP16 (1:1 ratio), while the MX550 manages 2.703 TFLOPS in both. The bus interface also differs: the RTX 5070 Mobile uses PCIe 5.0 x16, while the MX550 uses PCIe 4.0 x8. The MX550 is marked as end-of-life, while the RTX 5070 Mobile is active and was released on April 14, 2025; the MX550’s release date is December 16, 2021.

Architecture Differences

The architectural gap between these two GPUs is generational. The RTX 5070 Mobile uses the Blackwell 2.0 architecture on the GB206 chip, while the MX550 relies on the Turing architecture with the TU117SB chip. Blackwell 2.0 is a modern design with dedicated RT cores (36 of them) and tensor cores (144 of them), enabling hardware-accelerated ray tracing and AI workloads. The MX550, based on Turing, has no RT cores and no tensor cores, so it cannot offload those tasks to dedicated hardware. This is a fundamental functional difference, not just a performance gap.

The RTX 5070 Mobile supports DirectX 12 Ultimate (12_2), which includes features like mesh shaders, variable rate shading, and DXR ray tracing. The MX550 supports DirectX 12 (12_1), which lacks some of the advanced features of 12_2. Both support OpenGL 4.6 and Vulkan 1.4, so API coverage is otherwise equal. The manufacturing process is another key differentiator: the RTX 5070 Mobile is fabbed on a 5 nm process at TSMC, while the MX550 uses a 12 nm process also at TSMC. The smaller node allows for higher transistor density (121.0M per mm² vs. 23.5M per mm²), which is the root cause of the RTX 5070 Mobile’s massive compute advantage.

Power delivery also differs. The RTX 5070 Mobile has a TDP of 50 W, while the MX550 is rated at 25 W. Both are IGP (integrated graphics processor) form factors with no power connectors, and both rely on the host system for power. The RTX 5070 Mobile’s higher TDP is justified by its 13.13 TFLOPS FP32 throughput, which is nearly five times the MX550’s 2.703 TFLOPS. The generation gap is also visible in the release timeline: the RTX 5070 Mobile is part of the GeForce 50 Mobile series, succeeding the GeForce 40 Mobile, while the MX550 is a standalone product in the GeForce MX (5xx) series with no predecessor or successor recorded. The RTX 5070 Mobile’s display outputs are portable device dependent, as are the MX550’s, so both are designed exclusively for laptops. In summary, the RTX 5070 Mobile is a next-generation, feature-rich GPU with dedicated hardware for modern workloads, while the MX550 is a legacy Turing part aimed at basic acceleration tasks. The architecture differences alone explain the benchmark results, and the data confirms that the RTX 5070 Mobile is the superior product in every measured category.
