NVIDIA B300 vs NVIDIA GeForce RTX 3050 A Mobile Comparison

Head-to-Head Benchmarks

The recorded data for the NVIDIA B300 and the NVIDIA GeForce RTX 3050 A Mobile comes from entirely different segments of the database. The B300 is a server-class accelerator with no benchmark entries, while the RTX 3050 A Mobile has a full suite of eight recorded tests. The head-to-head comparison is therefore defined by the absence of data for one side rather than direct numerical competition.

The RTX 3050 A Mobile delivers a Geekbench OpenCL score of 52,998. Its Passmark suite shows a DirectX 9 score of 152, DirectX 10 at 61, DirectX 11 at 94, and DirectX 12 at 55. The 2D graphics score is 526, while the 3D score reaches 11,664. The GPU compute score is 4,419. These figures place the mobile part at the 44th percentile of all GPUs in the database, with an average benchmark score of 8,746.

The B300 has no benchmark scores recorded, no average score, and no percentile ranking beyond a neutral 50th percentile placeholder. Its nearest rivals list is empty. The database shows zero wins for either product in the head-to-head benchmark section. This means the comparison cannot rely on measured performance deltas. Instead, the relevant comparison is between the RTX 3050 A Mobile's measured results and the B300's architectural specifications, which indicate a vastly different performance envelope.

The RTX 3050 A Mobile's closest competitors in the database include the NVIDIA GeForce GTX 460 v2 with an average score of 8,743 and a delta of 0 percent, the NVIDIA Quadro P2200 at 8,686 with a 0.7 percent delta, the AMD Radeon R9 M265X at 8,851 with a negative 1.2 percent delta, and the AMD Radeon Pro WX 5100 at 8,863 with a negative 1.3 percent delta. These rivals bracket the mobile part within a narrow performance band, showing that the RTX 3050 A Mobile sits nearly level with several older desktop and workstation parts.

The Verdict

The data indicates two products built for different purposes. The B300 is a server module with a 1400 W TDP, SXM form factor, and no display outputs. The RTX 3050 A Mobile is a 45 W integrated graphics processor for portable devices, with outputs dependent on the host laptop. The B300 targets compute workloads in data centers, while the RTX 3050 A Mobile targets mainstream laptop graphics.

Benchmark results indicate the RTX 3050 A Mobile delivers usable DirectX 9, 10, 11, and 12 performance, plus OpenCL compute capability. Its average score of 8,746 places it in the 44th percentile of all GPUs. The B300 has no such measurements, so no direct performance claim can be made from the database. What the data does show is a difference in scale: the B300 uses 104,000 million transistors on a 5 nm TSMC process, while the RTX 3050 A Mobile uses 12,000 million transistors on an 8 nm Samsung process. The B300's FP32 throughput is 76.99 TFLOPS, its FP16 throughput is 1,231.8 TFLOPS, and its memory bandwidth is 4.10 TB/s. The RTX 3050 A Mobile delivers 4.813 TFLOPS FP32 and 192.0 GB/s bandwidth.

The verdict from the recorded data is straightforward: the RTX 3050 A Mobile is a measured, end-of-life mobile GPU with known benchmark results and a defined competitive position. The B300 is an active server accelerator with no benchmark data in the database, meaning any performance comparison would require separate measurements not present here. Users seeking a laptop GPU with documented DirectX and OpenCL scores have that information for the RTX 3050 A Mobile. Users evaluating the B300 must rely on its specifications alone.

Where Each One Wins

The RTX 3050 A Mobile wins in the category of available benchmark data. It has eight recorded tests covering DirectX 9 through 12, OpenCL, 2D, 3D, and compute workloads. Its 3D score of 11,664 and OpenCL score of 52,998 provide concrete reference points. The B300 has zero recorded benchmarks, so it cannot claim any measured victory in this database.

The B300 wins on raw specification scale. Its 144 GB of HBM3e memory dwarfs the RTX 3050 A Mobile's 4 GB of GDDR6. The B300's 4096-bit memory bus versus the mobile part's 128-bit bus corresponds to a 4.10 TB/s bandwidth versus 192.0 GB/s. The B300's 18,944 shading units, 592 tensor cores, and 592 TMUs far exceed the RTX 3050 A Mobile's 1,792 shading units, 56 tensor cores, and 56 TMUs. The B300's texture rate is 1,202.9 GTexel/s compared to 75.21 GTexel/s for the mobile part.

The RTX 3050 A Mobile wins on power efficiency in practical terms. Its 45 W TDP requires no power connectors and no suggested PSU. The B300 requires a 1400 W TDP and a suggested 1800 W PSU. The mobile part is an IGP, meaning it sits inside a laptop with no separate module. The B300 is an SXM module, a form factor for server chassis.

The RTX 3050 A Mobile also wins on API support in the recorded data. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B300 has no API entries in the database, so no compatibility claim can be made. The mobile part's display outputs are listed as portable device dependent, whereas the B300 has no outputs at all.
