NVIDIA GeForce RTX 3050 A Mobile vs NVIDIA H20 Comparison

The Verdict

The database records two fundamentally different NVIDIA products: the GeForce RTX 3050 A Mobile and the H20. The RTX 3050 A Mobile is an end-of-life mobile graphics processor from the GeForce 30-series, built for portable devices with a 45 W power envelope. The H20 is an active server accelerator from the Hopper generation, designed for datacenter compute with a 500 W power draw and no display outputs. Based strictly on recorded data, the RTX 3050 A Mobile has a complete set of benchmark scores, while the H20 has no recorded benchmark entries. The RTX 3050 A Mobile sits at the 44th percentile of all GPUs in the database, with an average benchmark score of 8746. The H20 sits at the 50th percentile, but its average benchmark score is recorded as zero, meaning no direct performance comparison can be drawn from the measurements. The data shows that the RTX 3050 A Mobile is the only one of the two with verifiable graphics performance metrics, making it the choice for any workload requiring confirmed DirectX, OpenGL, or Vulkan support. The H20, with no graphics API support recorded and no display outputs, is a compute-only accelerator, so it is not a substitute for the mobile GPU in any graphics-oriented task. For users needing a mobile graphics solution with measured performance, the RTX 3050 A Mobile is the only option supported by data. For users needing a high-capacity server accelerator with 96 GB of HBM3 memory and 4.03 TB/s of bandwidth, the H20 is the only option that matches that profile, but its performance remains unmeasured in the database.

Architecture Differences

The RTX 3050 A Mobile uses the GA106 chip on Samsung's 8 nm process, with 12,000 million transistors on a 276 mm² die, yielding a transistor density of 43.5M per mm².

The RTX 3050 A Mobile is an IGP with portable device dependent display outputs; the H20 is an SXM module with no display outputs.

Where Each One Wins

The RTX 3050 A Mobile wins in all recorded graphics benchmark categories because it is the only one with benchmark data. The database lists eight benchmark scores for the RTX 3050 A Mobile: Geekbench OpenCL at 52998, Passmark DirectX 10 at 61, Passmark DirectX 11 at 94, Passmark DirectX 12 at 55, Passmark DirectX 9 at 152, Passmark G2D at 526, Passmark G3D at 11664, and Passmark GPU Compute at 4419. The H20 has zero benchmark entries, so it has no recorded wins in any graphics test.

For graphics rendering workloads, the RTX 3050 A Mobile is the only option with measured DirectX performance. Its Passmark DirectX 9 score of 152 is the highest among its DirectX scores, indicating stronger legacy API performance relative to newer APIs. Its Passmark DirectX 11 score of 94 is notably higher than its DirectX 12 score of 55. The Passmark G3D score of 11664 places it in the 44th percentile of all GPUs, with nearest rivals including the NVIDIA GeForce GTX 460 v2 (average score 8743, delta 0%), the NVIDIA Quadro P2200 (average score 8686, delta 0.7%), the AMD Radeon R9 M265X (average score 8851, delta -1.2%), and the AMD Radeon Pro WX 5100 (average score 8863, delta -1.3%). This means the RTX 3050 A Mobile performs essentially on par with the GTX 460 v2, is 0.7% ahead of the Quadro P2200, is 1.2% behind the R9 M265X, and is 1.3% behind the Pro WX 5100.

The H20 wins in every recorded specification category except ROP count. It has more shading units, more TMUs, more tensor cores, higher clocks, more memory, wider bus, higher bandwidth, higher pixel rate, higher texture rate, higher FP32, and higher FP16. It uses a smaller process node, has a higher transistor density, and supports PCIe 5.0 x16. The H20 is also an active production part, while the RTX 3050 A Mobile is end-of-life. The H20's release date is 2024-02-01, while the RTX 3050 A Mobile's release date is 2024-01-01. The H20 has a successor (Server Blackwell), while the RTX 3050 A Mobile has no recorded successor. The RTX 3050 A Mobile's predecessor is GeForce 20 Mobile, while the H20's predecessor is Server Ada.

For compute-heavy tasks that rely on FP16 throughput, the H20's 79.07 TFLOPS is 16.4 times the RTX 3050 A Mobile's 4.813 TFLOPS. For FP32 tasks, the H20's 39.54 TFLOPS is 8.2 times higher. For memory bandwidth bound workloads, the H20's 4.03 TB/s dwarfs the RTX 3050 A Mobile's 192.0 GB/s. For texture-heavy workloads, the H20's 617.8 GTexel/s is 8.2 times higher. However, none of these advantages appear in benchmark scores because the H20 has no recorded benchmarks.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the RTX 3050 A Mobile and the H20. The head-to-head array is empty, with zero wins recorded for either side. This means no direct comparative measurement exists in the database. However, the RTX 3050 A Mobile's standalone benchmark scores provide a reference point. Its Geekbench OpenCL score of 52998 is its highest recorded score. Its Passmark G3D score of 11664 is its second highest. Its Passmark GPU Compute score is 4419. Its Passmark G2D score is 526. Its DirectX scores are lower: DirectX 9 at 152, DirectX 11 at 94, DirectX 10 at 61, and DirectX 12 at 55.

The average benchmark score for the RTX 3050 A Mobile is 8746, placing it at the 44th percentile of all GPUs in the database. The H20's average benchmark score is recorded as zero, placing it at the 50th percentile despite having no measurements. This discrepancy means the H20's percentile ranking is not supported by actual performance data. The RTX 3050 A Mobile's nearest rivals in the database are all within 1.3% of its average score. The GTX 460 v2 matches it exactly at 8743 (delta 0%). The Quadro P2200 is 0.7% ahead. The R9 M265X is 1.2% behind. The Pro WX 5100 is 1.3% behind.

Looking at specific workload categories, the RTX 3050 A Mobile shows its strongest relative performance in Passmark G3D with a score of 11664, which is 2.6 times its average score. Its Passmark GPU Compute score of 4419 is about half its average score. Its Geekbench OpenCL score of 52998 is far above any Passmark score, though the tests measure different workloads. The DirectX scores are the weakest: DirectX 12 at 55 is 63% lower than DirectX 11 at 94, and DirectX 10 at 61 is 60% lower than DirectX 9 at 152. This pattern suggests the RTX 3050 A Mobile handles legacy DirectX 9 workloads better than newer DirectX 12 workloads, based on the recorded data.

The H20 has no benchmark scores to compare directly. Its specification sheet indicates capabilities that would likely produce high compute scores, given its 39.54 TFLOPS FP32 and 79.07 TFLOPS FP16, but the database records no measurements to confirm this. The RTX 3050 A Mobile's FP32 of 4.813 TFLOPS is 8.2 times lower than the H20's, and its FP16 of 4.813 TFLOPS is 16.4 times lower. The texture rate difference is also 8.2 times in favor of the H20. These specification gaps are large, but without benchmark data for the H20, no performance delta can be quantified from measurements. The database records zero wins for each side in the head-to-head comparison, meaning the only verifiable performance data belongs to the RTX 3050 A Mobile.
