NVIDIA GB10 vs NVIDIA GeForce RTX 3050 A Mobile Comparison

Head-to-Head Benchmarks

The recorded head-to-head data contains a single direct comparison: Geekbench OpenCL. In this test, the NVIDIA GB10 scores 120137 points, while the NVIDIA GeForce RTX 3050 A Mobile scores 52998 points. This gives the GB10 a decisive 126.7% advantage, meaning it more than doubles the mobile part's raw compute throughput in this workload. The delta is so large that it places the two products in entirely different performance strata.

Looking at the broader benchmark database, the GB10's average score of 117393 places it in the 95th percentile of all GPUs. Its nearest rivals include the NVIDIA RTX 4000 SFF Ada Generation (average score 117088, a mere 0.3% behind), the AMD Radeon PRO W7700 (118976, 1.3% ahead), the NVIDIA Tesla V100 SXM2 16 GB (114395, 2.6% behind), and the NVIDIA RTX A5500 Mobile (113944, 3% behind). The GB10's position here is tight: it sits slightly above the RTX 4000 SFF Ada and below the Radeon PRO W7700, indicating data center-class performance with minimal separation from its immediate competitors.

The RTX 3050 A Mobile, by contrast, holds a 44th percentile ranking with an average score of 8746. Its nearest rivals are far older or lower-tier parts: the GeForce GTX 460 v2 (8743, 0% delta), the Quadro P2200 (8686, 0.7% behind), the Radeon R9 M265X (8851, 1.2% ahead), and the Radeon Pro WX 5100 (8863, 1.3% ahead). The RTX 3050 A Mobile is effectively neck-and-neck with these legacy or mid-range workstation cards, which underscores how far behind the GB10 it sits in raw compute.

The 126.7% OpenCL delta is the only direct head-to-head measurement, but the percentile rankings reinforce the same story. The GB10 outperforms the RTX 3050 A Mobile by roughly 13.4 times in average benchmark score (117393 versus 8746). That is not a marginal gap; it is a chasm. The GB10 also shows a 114648 score in Geekbench Vulkan, which has no direct counterpart for the RTX 3050 A Mobile in the database, but the OpenCL result alone establishes the hierarchy.

Architecture Differences

The two GPUs come from different architectural generations and manufacturing processes. The GB10 uses the Blackwell 2.0 architecture on a 5 nm process at TSMC, with a die size of 382 mm². The RTX 3050 A Mobile uses the older Ampere architecture on an 8 nm process at Samsung, with a die size of 276 mm² and a transistor count of 12,000 million. The GB10's transistor count is listed as unknown, but its larger die on a denser process suggests a substantially higher transistor budget.

The GB10 is built for server workloads, belonging to the Server Blackwell (Bxx) generation, while the RTX 3050 A Mobile belongs to the GeForce 30 Mobile series. This fundamental positioning explains many differences. The GB10 has 6144 shading units, 384 TMUs, 48 ROPs, 48 RT cores, and 384 tensor cores. The RTX 3050 A Mobile has 1792 shading units, 56 TMUs, 32 ROPs, 14 RT cores, and 56 tensor cores. The GB10 has roughly 3.4 times the shading units and 6.9 times the tensor cores.

Memory configurations diverge sharply. The GB10 carries 128 GB of LPDDR5X on a 256-bit bus, delivering 273.2 GB/s of bandwidth. The RTX 3050 A Mobile has 4 GB of GDDR6 on a 128-bit bus, yielding 192.0 GB/s. The GB10 has 32 times the memory capacity and 1.4 times the bandwidth. Clock speeds also differ: the GB10 runs at a base of 1665 MHz and a boost of 2418 MHz, while the RTX 3050 A Mobile runs at 1065 MHz base and 1343 MHz boost. The GB10's memory clock is listed as 1067 MHz (8.5 Gbps effective) versus 1500 MHz (12 Gbps effective) for the RTX 3050 A Mobile, but the wider bus more than compensates.

The GB10's API support is listed as N/A for DirectX, OpenGL, and Vulkan, reflecting its server-oriented design with no consumer graphics API exposure. The RTX 3050 A Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This is a critical distinction: the GB10 is not designed for traditional graphics rendering, while the RTX 3050 A Mobile is a full-featured consumer GPU.

Power envelopes are also divergent. The GB10 has a TDP of 140 W, while the RTX 3050 A Mobile draws only 45 W. The GB10 requires a suggested 300 W PSU, while the RTX 3050 A Mobile lists no suggested PSU (it is a mobile part). Both are IGP slot-width designs with no power connectors. The GB10 uses PCIe 5.0 x16, while the RTX 3050 A Mobile uses PCIe 4.0 x8. The GB10 has a single HDMI output, while the RTX 3050 A Mobile's display outputs are portable-device dependent.

Where Each One Wins

The GB10 wins every recorded direct benchmark, but the nature of the workloads matters. The Geekbench OpenCL result (120137 versus 52998) reflects compute-heavy parallel processing, which aligns with the GB10's server DNA. The GB10's 29.71 TFLOPS FP32 and 29.71 TFLOPS FP16 (1:1) throughput dwarfs the RTX 3050 A Mobile's 4.813 TFLOPS for both formats. For machine learning inference, scientific simulation, or any FP16-heavy workload, the GB10 is the clear choice.

The RTX 3050 A Mobile's domain is conventional graphics. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, meaning it can run modern games and graphics applications. The GB10 has no API support listed, so it cannot drive traditional rendering workloads. The RTX 3050 A Mobile's Passmark scores, while modest, show functionality: DirectX 9 at 152, DirectX 10 at 61, DirectX 11 at 94, DirectX 12 at 55, G2D at 526, G3D at 11664, and GPU compute at 4419. These numbers indicate a working graphics card, albeit one at the low end of the GeForce 30 mobile stack.

The GB10's memory capacity (128 GB) makes it suited for large datasets that cannot fit in the RTX 3050 A Mobile's 4 GB. The GB10 also has a higher pixel rate (116.1 GPixel/s versus 42.98 GPixel/s) and texture rate (928.5 GTexel/s versus 75.21 GTexel/s), though these rates matter less for a server part. The GB10's 140 W TDP versus 45 W TDP reflects the performance gap: the GB10 consumes more power but delivers far more compute per watt in absolute terms.

The RTX 3050 A Mobile wins on portability and power efficiency. At 45 W, it can be integrated into thin laptops. The GB10, at 140 W with a 150 mm length, 51 mm height, and 150 mm width, is a larger IGP design intended for server boards. The RTX 3050 A Mobile has no listed dimensions, but its mobile nature implies a smaller footprint.

The Verdict

The data presents a clear split: the GB10 is a server compute accelerator, while the RTX 3050 A Mobile is a low-power mobile graphics processor. The GB10's 126.7% OpenCL lead over the RTX 3050 A Mobile, combined with its 95th percentile ranking versus the RTX 3050 A Mobile's 44th percentile, establishes the GB10 as vastly more powerful for compute tasks. The GB10's 128 GB memory, 6144 shading units, and 384 tensor cores are server-grade specifications.

The RTX 3050 A Mobile's advantages are limited to graphics API support, lower power draw, and portability. It can run DirectX 12 Ultimate titles and OpenGL applications, which the GB10 cannot. For a user needing a discrete GPU for gaming or workstation graphics on a laptop, the RTX 3050 A Mobile is the only option of the two. For a user needing raw compute for AI, scientific, or data center workloads, the GB10 is overwhelmingly superior.

The GB10's launch MSRP is 3,999 USD, and it is listed as Active in production. The RTX 3050 A Mobile is End-of-life with no launch MSRP. The GB10's predecessor is Server Hopper, and its successor is Server Rubin, confirming its server lineage. The RTX 3050 A Mobile's predecessor is GeForce 20 Mobile, with no successor listed. The GB10 released on 2025-10-14, while the RTX 3050 A Mobile released on 2023-12-31. The GB10 is the newer, more capable part by every compute metric.

The verdict from the database is unambiguous: pick the GB10 for compute performance and large memory capacity; pick the RTX 3050 A Mobile only if graphics API compatibility or a 45 W power budget is mandatory.
