NVIDIA GeForce RTX 3050 A Mobile vs NVIDIA RTX 4000 SFF Ada Generation Comparison

The NVIDIA GeForce RTX 3050 A Mobile and the NVIDIA RTX 4000 SFF Ada Generation occupy different corners of the GPU market. One is a low-power mobile part aimed at thin-and-light laptops, while the other is a dual-slot workstation card for compact desktops. The database contains only one directly comparable benchmark result, but the specification sheets reveal a massive performance gap and entirely different design philosophies.

Where Each One Wins

The RTX 3050 A Mobile wins in situations where power draw and physical footprint are the primary constraints. Its 45 W TDP and IGP slot width mean it can be integrated into systems without dedicated power connectors or expansion slots. This makes it suitable for portable devices where space is at a premium. The card's performance profile, while modest, is sufficient for basic 3D acceleration and older DirectX workloads. Its Passmark scores show strength in DirectX 9 (152 points) and DirectX 11 (94 points) relative to its other results, though the absolute numbers are low.

The RTX 4000 SFF Ada Generation wins everywhere else. It delivers over twice the Geekbench OpenCL score, offers 20 GB of memory versus 4 GB, and sits in the 95th percentile of all GPUs in the database. The RTX 3050 A Mobile, by contrast, sits in the 44th percentile. For compute-heavy tasks, professional rendering, or any workload that can leverage the Ada Lovelace architecture's hardware features, the RTX 4000 SFF is the clear choice. Its nearest rivals in the database include the NVIDIA Tesla V100 SXM2 16 GB (2.4% slower), the AMD Radeon PRO W7700 (1.6% faster), and the NVIDIA RTX A5500 Mobile (2.8% slower), placing it in high-end workstation territory.

Head-to-Head Benchmarks

The only direct benchmark comparison in the database is Geekbench OpenCL. The RTX 4000 SFF Ada Generation scores 124812, while the RTX 3050 A Mobile scores 52998. This represents a 57.5% deficit for the mobile part. In absolute terms, the workstation card delivers roughly 2.35 times the OpenCL performance of the mobile GPU.

Beyond that single result, the average benchmark scores tell a similar story. The RTX 4000 SFF has an average benchmark score of 117088, placing it at the 95th percentile of all GPUs. The RTX 3050 A Mobile has an average score of 8746, placing it at the 44th percentile. The nearest rival to the RTX 3050 A Mobile in the database is the NVIDIA GeForce GTX 460 v2 with an average score of 8743 (0% difference), followed by the NVIDIA Quadro P2200 at 8686 (0.7% faster). The RTX 4000 SFF's nearest rival is the NVIDIA GB10 at 117393 (0.3% faster), with the AMD Radeon PRO W7700 at 118976 (1.6% faster) close behind.

The RTX 3050 A Mobile's individual benchmark results show its limitations. Its Passmark DirectX 9 score of 152 is its highest DirectX result, followed by DirectX 11 at 94, DirectX 10 at 61, and DirectX 12 at 55. Its Passmark G3D score is 11664, and its GPU compute score is 4419. These numbers are all in the low range, consistent with a 44th percentile overall ranking. The RTX 4000 SFF does not have Passmark results in the database, but its Geekbench Vulkan score of 109364 provides additional evidence of its compute capability beyond OpenCL.

Specification Differences

The memory subsystems differ sharply. The RTX 3050 A Mobile uses 4 GB of GDDR6 with a 128-bit bus, yielding 192.0 GB/s of bandwidth. The RTX 4000 SFF uses 20 GB of GDDR6 with a 160-bit bus, yielding 280.0 GB/s. Memory clock is also higher on the workstation card: 1750 MHz (14 Gbps effective) versus 1500 MHz (12 Gbps effective) on the mobile part.

The compute resources show a similar gap. The RTX 3050 A Mobile has 1792 shading units, 56 texture mapping units, and 32 ROPs. The RTX 4000 SFF has 6144 shading units, 192 TMUs, and 64 ROPs. The RTX 4000 SFF also has 48 RT cores and 192 tensor cores, compared to 14 RT cores and 56 tensor cores on the RTX 3050 A Mobile.

Pixel and texture rates reflect these differences. The RTX 3050 A Mobile achieves 42.98 GPixel/s and 75.21 GTexel/s. The RTX 4000 SFF achieves 99.84 GPixel/s and 299.5 GTexel/s. FP32 and FP16 performance are both rated at 4.813 TFLOPS for the mobile card, while the workstation card delivers 19.17 TFLOPS in both precision modes.

Power and physical design diverge completely. The RTX 3050 A Mobile has a 45 W TDP, is IGP-class with no slot width, and requires no power connectors. The RTX 4000 SFF has a 70 W TDP, is dual-slot, uses no power connectors, and specifies a 250 W suggested PSU. The RTX 4000 SFF measures 168 mm (6.6 inches) in length and 69 mm (2.7 inches) in height. The RTX 3050 A Mobile has no listed dimensions.

Bus interfaces also differ: the RTX 3050 A Mobile uses PCIe 4.0 x8, while the RTX 4000 SFF uses PCIe 4.0 x16. Display outputs are "portable device dependent" on the mobile part, while the RTX 4000 SFF has 4x mini-DisplayPort 1.4a.

Architecture Differences

The two GPUs come from different architecture generations. The RTX 3050 A Mobile uses the Ampere architecture with the GA106 chip, built on an 8 nm process at Samsung. The RTX 4000 SFF uses the Ada Lovelace architecture with the AD104 chip, built on a 5 nm process at TSMC.

The transistor counts show the scale of difference. The GA106 chip contains 12,000 million transistors on a 276 mm² die, giving a transistor density of 43.5 million per mm². The AD104 chip contains 35,800 million transistors on a 294 mm² die, giving a transistor density of 121.8 million per mm². The Ada Lovelace chip packs nearly three times the transistors into a similar die area.

The RTX 3050 A Mobile belongs to the GeForce 30 Mobile generation, with the GeForce 20 Mobile as its predecessor. The RTX 4000 SFF belongs to the Workstation Ada generation, with Workstation Ampere as its predecessor and Blackwell PRO W as its successor. The RTX 3050 A Mobile is end-of-life, while the RTX 4000 SFF remains active.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 4000 SFF has a higher boost clock (1560 MHz versus 1343 MHz) despite a lower base clock (720 MHz versus 1065 MHz). The RTX 4000 SFF also has a much higher transistor density, reflecting the more advanced 5 nm process.

The Verdict

The data points to a straightforward conclusion for most buyers. The RTX 4000 SFF Ada Generation outperforms the RTX 3050 A Mobile by a wide margin in every measurable category: raw compute, memory capacity, bandwidth, shading units, RT cores, tensor cores, and pixel/texture throughput. Its 95th percentile ranking versus the 44th percentile ranking of the mobile part confirms that these are not competing products.

The RTX 3050 A Mobile serves a specific niche: low-power mobile computing. Its 45 W TDP, IGP form factor, and lack of power connectors make it suitable for thin laptops where performance expectations are modest. Its 4 GB memory and 128-bit bus are sufficient for basic 3D workloads and older API titles, as shown by its relatively higher DirectX 9 and DirectX 11 Passmark scores. For users who need a discrete GPU in a portable device without sacrificing battery life or chassis space, the RTX 3050 A Mobile fits that role.

The RTX 4000 SFF Ada Generation targets professional workstations. Its 20 GB memory capacity, 280.0 GB/s bandwidth, and 19.17 TFLOPS FP32 performance handle large datasets and compute-heavy tasks. The dual-slot design and 168 mm length indicate a desktop-oriented card, despite its modest 70 W TDP. The 250 W suggested PSU requirement is minimal for a workstation. Its nearest rivals include high-end accelerators like the Tesla V100 SXM2 and the RTX A5500 Mobile, confirming its position in the upper tier of GPU performance.

For a laptop buyer, the RTX 3050 A Mobile is the only option between these two. For anyone building a compact workstation or desktop, the RTX 4000 SFF offers dramatically more performance without requiring a large power supply or multiple slots. The benchmark gap of 57.5% in Geekbench OpenCL, combined with a 5x memory capacity advantage and 4x shading unit advantage, leaves no ambiguity about which GPU delivers more capability. The RTX 4000 SFF is the superior product on every axis except power draw and physical footprint.
