Intel Arc A770M vs NVIDIA GeForce RTX 4050 Mobile Comparison

The NVIDIA GeForce RTX 4050 Mobile and the Intel Arc A770M represent two very different approaches to high-performance mobile graphics. The data shows a clear split: the RTX 4050 Mobile wins the majority of benchmark comparisons, but the Arc A770M claims decisive victories in specific workloads that highlight its raw hardware muscle. This analysis breaks down where each GPU excels, the architectural choices behind their performance, and which type of user should favor one over the other based strictly on the benchmark results.

Where Each One Wins

The benchmark suite gives each GPU a distinct profile. The NVIDIA GeForce RTX 4050 Mobile takes six of the nine head-to-head tests, establishing itself as the more consistent performer across a broad range of legacy and modern APIs. Its wins are particularly pronounced in DirectX 11, where it scores 130 versus Intel’s 69, a staggering 88.4% advantage. This suggests the RTX 4050 Mobile is the safer pick for older game titles and applications that rely on mature driver optimizations for DirectX 11.

The RTX 4050 Mobile also dominates in the PassMark G3D test, scoring 14,423 against Intel’s 11,774, a 22.5% lead. This is the most holistic gaming-oriented metric in the pack, and it reinforces the NVIDIA part’s strength in general 3D rendering. Its win in PassMark GPU Compute (5,947 vs. 4,778, a 24.5% advantage) further indicates that the RTX 4050 Mobile handles general-purpose compute tasks more efficiently in this specific test suite.

The Intel Arc A770M, conversely, wins only three tests, but they are significant. Its most notable victory is in Geekbench OpenCL, where it scores 89,494 against NVIDIA’s 74,748, a 16.5% lead. This points to raw compute throughput that can be leveraged in productivity and content creation applications that use OpenCL. The Arc A770M also wins in PassMark DirectX 12 (70 vs. 61, a 12.9% lead) and PassMark G2D (711 vs. 633, an 11% lead). The DirectX 12 win is crucial, as it suggests the Intel GPU has a stronger foundation for the latest graphics API, even if its overall 3D score trails.

Architecture Differences

The two GPUs are built on fundamentally different silicon. The NVIDIA GeForce RTX 4050 Mobile uses the AD107 chip, based on the Ada Lovelace architecture, fabricated on a 5 nm process at TSMC. It packs 18,900 million transistors into a die size of 159 mm², resulting in a transistor density of 118.9 million per square millimeter. This is a dense, power-efficient design.

The Intel Arc A770M uses the DG2-512 chip, based on the Xe-HPG architecture, also built by TSMC but on a 6 nm process. This chip is significantly larger, with 21,700 million transistors spread across 406 mm², giving it a much lower transistor density of 53.4 million per square millimeter. The Intel chip has more raw hardware, but it is less dense and requires more power.

These architectural differences manifest in the specs. The Arc A770M has 4,096 shading units, 256 TMUs, and 128 ROPs, compared to the RTX 4050 Mobile’s 2,560 shading units, 80 TMUs, and 48 ROPs. The Intel part also has 32 ray tracing cores versus NVIDIA’s 20. The Arc A770M’s FP32 compute is listed at 16.79 TFLOPS, nearly double the RTX 4050 Mobile’s 8.986 TFLOPS. Its FP16 performance is even more stark, hitting 33.59 TFLOPS with a 2:1 rate, while the NVIDIA card achieves 8.986 TFLOPS at a 1:1 rate.

Memory is another major divergence. The RTX 4050 Mobile has 6 GB of GDDR6 on a 96-bit bus, yielding 192.0 GB/s of bandwidth. The Arc A770M offers 16 GB of GDDR6 on a 256-bit bus, providing 512.0 GB/s of bandwidth. This massive bandwidth advantage (2.67 times) is a key reason for the Intel card’s strong OpenCL and DirectX 12 scores. The power envelope also differs: the RTX 4050 Mobile has a 50 W TDP, while the Arc A770M is rated at 120 W. The NVIDIA card uses a PCIe 4.0 x8 interface, while Intel uses a full x16 link. Both support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4.

Head-to-Head Benchmarks

The largest single win for the NVIDIA GeForce RTX 4050 Mobile comes in the PassMark DirectX 11 test. With a score of 130 versus the Intel’s 69, the NVIDIA card is 88.4% faster. This is a massive gap that indicates the Ada Lovelace architecture has a significant advantage in legacy API performance, likely due to more mature driver overhead management.

The next biggest win for NVIDIA is in PassMark DirectX 10, where it scores 79 against Intel’s 56, a 41.1% lead. This pattern of dominance in older APIs continues with DirectX 9, where the RTX 4050 Mobile wins 184 to 178, a smaller 3.4% margin. These results collectively show that the RTX 4050 Mobile is the better choice for running a back catalog of games that use DirectX 9, 10, and 11.

In the more modern DirectX 12 test, the tables turn. The Intel Arc A770M scores 70, beating the RTX 4050 Mobile’s 61 by 12.9%. While the absolute scores are close, this win is significant because DirectX 12 is the foundation for current and future AAA titles. The Intel card’s advantage here may stem from its higher raw compute throughput and bandwidth, which are better utilized by the low-level API.

The Geekbench OpenCL test provides the Intel card’s largest overall victory. Its score of 89,494 is 16.5% higher than the RTX 4050 Mobile’s 74,748. This suggests that for compute-heavy tasks that scale well with more shading units and memory bandwidth, the Arc A770M is the superior part. However, in Geekbench Vulkan, the NVIDIA card edges out a win with 75,235 versus 74,422, a narrow 1.1% margin.

The PassMark G3D and GPU Compute tests are decisive for NVIDIA. The G3D score of 14,323 versus 11,774 represents a 22.5% lead, and the GPU Compute score of 5,947 versus 4,778 is a 24.5% lead. These are the most substantial wins for NVIDIA after the DirectX 10 and 11 results, cementing its position as the better overall gaming and compute GPU in this comparison. The Intel card only manages a win in PassMark G2D, scoring 711 to 633, an 11% lead, which is a 2D graphics test and less relevant for gaming.
