NVIDIA GeForce RTX 3050 A Mobile vs NVIDIA RTX PRO 4500 Blackwell Comparison

The Verdict

The recorded data presents a decisive hierarchy: the NVIDIA RTX PRO 4500 Blackwell outperforms the NVIDIA GeForce RTX 3050 A Mobile in every single benchmark category where both were measured. The RTX PRO 4500 Blackwell wins all seven head-to-head comparisons, with no wins for the RTX 3050 A Mobile. The average benchmark score for the RTX PRO 4500 Blackwell is 31,532, which places it at the 76th percentile of all GPUs in the database. The RTX 3050 A Mobile, with an average score of 8,746, sits at the 44th percentile. This is not a close contest; the RTX PRO 4500 Blackwell delivers roughly 3.6 times the average performance of the mobile GeForce part.

The target user for each card is clearly delineated by the data. The RTX 3050 A Mobile is a low-power, end-of-life mobile solution. Its 45 W TDP and integrated form factor (IGP) indicate it is intended for thin, portable laptops where battery life and thermals are prioritized over raw compute. Its 44th percentile standing shows it is a middling performer, even among all GPUs. The RTX PRO 4500 Blackwell, conversely, is an active, dual-slot workstation card with a 200 W TDP and a dedicated 16-pin power connector. Its 76th percentile rank and 32 GB of memory point to a professional workload focus: large datasets, complex 3D rendering, and AI inference tasks that require substantial memory capacity and compute throughput.

The performance gap is consistent across all API levels. In DirectX 10, 11, and 12 tests, the RTX PRO 4500 Blackwell leads by margins of 70.1%, 70.6%, and 53.8%, respectively. The largest relative advantage appears in the GPU compute test, where the RTX PRO 4500 Blackwell scores 19,255 versus 4,419 for the RTX 3050 A Mobile, a 77.1% lead. This pattern confirms that the workstation card is not just faster in graphics, but dramatically faster in general-purpose compute. The RTX 3050 A Mobile’s nearest rivals, including the NVIDIA GeForce GTX 460 v2 and the Quadro P2200, have average scores within 1.3% of its own, whereas the RTX PRO 4500 Blackwell’s closest competitor, the NVIDIA TITAN RTX, is only 0.5% ahead, underscoring that the Blackwell card operates in a different performance tier entirely.

Architecture Differences

The two GPUs represent entirely different architectural generations and design philosophies. The RTX 3050 A Mobile is built on the Ampere architecture, using the GA106 chip. It is fabricated on an 8 nm process at Samsung, housing 12,000 million transistors on a 276 mm² die. This results in a transistor density of 43.5M per mm². The RTX PRO 4500 Blackwell, in contrast, uses the Blackwell 2.0 architecture with the GB203 chip. It is manufactured on a 5 nm process at TSMC, packing 45,600 million transistors into a 378 mm² die, for a density of 120.6M per mm². The process node shrink and denser packing explain the massive increase in compute resources.

The core configurations diverge sharply. The RTX 3050 A Mobile has 1,792 shading units, 56 texture mapping units (TMUs), and 32 raster output units (ROPs). It includes 14 ray tracing cores and 56 tensor cores. The RTX PRO 4500 Blackwell scales this up enormously: 10,496 shading units, 328 TMUs, and 112 ROPs. It also carries 82 ray tracing cores and 328 tensor cores. The RTX PRO 4500 Blackwell has roughly 5.9 times the shading units and 5.9 times the TMUs of the mobile part, while its ROP count is 3.5 times higher. This explains the substantial fill-rate and texturing advantages.

Memory subsystems are also fundamentally different. The RTX 3050 A Mobile uses 4 GB of GDDR6 memory on a 128-bit bus, yielding 192.0 GB/s of bandwidth. The RTX PRO 4500 Blackwell uses 32 GB of GDDR7 memory on a 256-bit bus, delivering 896.0 GB/s. That is 4.7 times the bandwidth and 8 times the memory capacity. The memory clock also differs: the RTX 3050 A Mobile runs at 1500 MHz (12 Gbps effective), while the RTX PRO 4500 Blackwell runs at 1750 MHz (28 Gbps effective). These differences are critical for workstation tasks involving large textures or datasets that exceed the 4 GB capacity of the mobile card.

The interface and power delivery reflect their intended roles. The RTX 3050 A Mobile is an integrated graphics processor (IGP) with a PCIe 4.0 x8 interface and no power connectors. The RTX PRO 4500 Blackwell is a dual-slot card with a PCIe 5.0 x16 interface, a single 16-pin power connector, and a suggested 550 W PSU. The RTX PRO 4500 Blackwell is a physically large card: 267 mm long, 111 mm high, and 40 mm wide. The RTX 3050 A Mobile has no listed dimensions, as it is meant to be soldered onto a laptop board. Display outputs also differ: the RTX 3050 A Mobile is described as "Portable Device Dependent," while the RTX PRO 4500 Blackwell provides 4x DisplayPort 2.1b.

Specification Differences

The clock speeds show a clear separation. The RTX 3050 A Mobile has a base clock of 1065 MHz and a boost clock of 1343 MHz. The RTX PRO 4500 Blackwell operates at a base of 1635 MHz and boosts to 2407 MHz. The RTX PRO 4500 Blackwell's higher clocks, combined with its larger core count, result in dramatically higher theoretical throughput: its FP32 performance is 50.53 TFLOPS, compared to 4.813 TFLOPS for the RTX 3050 A Mobile. The same 1:1 ratio applies to FP16 performance for both cards.

Pixel and texture rates follow the same pattern. The RTX 3050 A Mobile achieves a pixel rate of 42.98 GPixel/s and a texture rate of 75.21 GTexel/s. The RTX PRO 4500 Blackwell reaches 269.6 GPixel/s and 789.5 GTexel/s, representing increases of roughly 6.3x and 10.5x, respectively. These figures indicate that the RTX PRO 4500 Blackwell is not just faster per clock, but is also clocked higher and has far more execution units.

Production status and release timing separate the two as well. The RTX 3050 A Mobile is listed as end-of-life, with a release date of December 31, 2023. Its predecessor is the GeForce 20 Mobile series. The RTX PRO 4500 Blackwell is an active product, released on March 17, 2025, and succeeds the Workstation Ada generation. The RTX PRO 4500 Blackwell supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, matching the API support of the older RTX 3050 A Mobile. Both cards share the same API feature set, meaning software compatibility is not a differentiator.

Head-to-Head Benchmarks

The head-to-head results are unambiguous: the RTX PRO 4500 Blackwell wins all seven recorded comparisons. The largest margin is in the Passmark GPU Compute test. The RTX PRO 4500 Blackwell scores 19,255, while the RTX 3050 A Mobile scores 4,419, a delta of 77.1%. This result indicates that the workstation card’s massive FP32 throughput and tensor core count translate directly into compute workloads, not just graphics.

The DirectX 11 test shows a similar gap. The RTX PRO 4500 Blackwell scores 320, versus 94 for the RTX 3050 A Mobile, a 70.6% lead. DirectX 10 follows closely: 204 versus 61, a 70.1% delta. These legacy API tests still show the newer architecture’s dominance, suggesting that raw shader throughput, rather than driver optimizations for modern APIs, drives the results.

The DirectX 9 test sees the RTX PRO 4500 Blackwell score 397 against 152 for the RTX 3050 A Mobile, a 61.7% advantage. The DirectX 12 test narrows the gap slightly in percentage terms: 119 versus 55, a 53.8% lead. This is the smallest delta of the seven tests, but the RTX PRO 4500 Blackwell still more than doubles the mobile card’s score. The 2D graphics test (Passmark G2D) shows a 60.6% lead for the RTX PRO 4500 Blackwell: 1,336 versus 526.

The most comprehensive test, Passmark G3D, shows the RTX PRO 4500 Blackwell at 33,360, against 11,664 for the RTX 3050 A Mobile, a 65% delta. This test aggregates multiple 3D workloads and confirms that the performance gap is consistent across different rendering scenarios. The RTX PRO 4500 Blackwell’s average benchmark score of 31,532 places it in the company of the NVIDIA TITAN RTX, which scores 31,676, a difference of only 0.5%. The RTX 3050 A Mobile’s average of 8,746 places it alongside the GeForce GTX 460 v2 (8,743) and Quadro P2200 (8,686), with deltas of 0% and 0.7%, respectively. The data places these two cards in completely different performance strata, with no overlap in their competitive sets.
