Architecture Differences

The N1X 48SM and RTX PRO 2000 Blackwell share the same Blackwell 2.0 architecture and both are fabricated on TSMC's 5 nm process, but they are built for fundamentally different roles. The N1X 48SM is an integrated graphics processor (IGP) with a GB20B chip and a die size of 382 mm², whereas the RTX PRO 2000 is a discrete workstation card with a GB206 chip measuring 181 mm². Transistor counts differ sharply: the RTX PRO 2000 packs 21,900 million transistors with a density of 121.0M per mm², while the N1X 48SM's transistor count is unknown.

The N1X 48SM carries substantially more compute resources. It has 6,144 shading units, 384 texture mapping units, 48 ROPs, 48 RT cores, and 192 tensor cores. The RTX PRO 2000 has 4,352 shading units, 136 TMUs, 48 ROPs, 34 RT cores, and 136 tensor cores. This means the IGP has 1,792 more shading units, 248 more TMUs, 14 more RT cores, and 56 more tensor cores. Both have the same 48 ROP count.

Clock behavior diverges: the N1X 48SM runs a 741 MHz base with a 2346 MHz boost, while the RTX PRO 2000 has a higher 982 MHz base but a lower 1957 MHz boost. Memory subsystems differ in type and capacity: the N1X 48SM uses 128 GB of LPDDR5X at 1067 MHz (8.5 Gbps effective) across a 256-bit bus, while the RTX PRO 2000 uses 16 GB of GDDR7 at 1125 MHz (18 Gbps effective) on a 128-bit bus. The discrete card still achieves higher bandwidth at 288.0 GB/s versus 273.2 GB/s.

The RTX PRO 2000 is a full-featured workstation GPU with DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 support. The N1X 48SM lists N/A for all three APIs, indicating it is not designed for standard desktop graphics API workloads. The RTX PRO 2000 connects via PCIe 5.0 x8, while the N1X 48SM uses PCIe 5.0 x16. The discrete card offers four mini-DisplayPort 2.1b outputs; the IGP has a single HDMI output.

Power and physical design also separate them. The RTX PRO 2000 is a dual-slot card with a 70 W TDP, no power connectors, and a 250 W suggested PSU. The N1X 48SM is an IGP with no slot width, no power connectors, and unknown TDP. The RTX PRO 2000 has defined dimensions of 167 mm by 69 mm by 20 mm; the N1X 48SM has none listed. The RTX PRO 2000's predecessor is listed as Workstation Ada, while the N1X 48SM has no predecessor or successor.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the N1X 48SM and RTX PRO 2000 Blackwell, and the N1X 48SM has zero recorded benchmark scores. All performance comparisons must therefore rely on the RTX PRO 2000's standalone measurements and its nearest rival deltas.

The RTX PRO 2000 shows its strongest result in Geekbench Vulkan with a score of 113,865, followed by Geekbench OpenCL at 106,087. In Passmark, the G3D score is 20,049, GPU compute is 8,396, and G2D is 1,303. DirectX-focused Passmark scores are much lower: DirectX 9 at 241, DirectX 11 at 174, DirectX 10 at 122, and DirectX 12 at 80. The 3DMark Steel Nomad DX12 test yields 2,374.5.

Relative to its nearest rivals, the RTX PRO 2000's average benchmark score of 25,269 places it within 2% of several competitors. It trails the AMD Radeon RX 6700M (25,633) by 1.4%, the AMD Radeon Pro W5700 (25,726) by 1.8%, and the NVIDIA GeForce RTX 3080 Ti Mobile (25,740) by 1.8%. It leads the NVIDIA RTX A5000 Mobile (24,763) by 2.0%. These margins are narrow enough that real-world application differences would likely outweigh raw score gaps.

The N1X 48SM's 50th percentile ranking versus the RTX PRO 2000's 70th percentile suggests the IGP sits below the discrete card in overall database standing. However, the N1X 48SM's theoretical compute resources are significantly higher: 28.83 TFLOPS FP32 versus 17.03 TFLOPS on the RTX PRO 2000, and identical 1:1 FP16 ratios at the same figures. The N1X 48SM also has a higher pixel rate at 112.6 GPixel/s versus 93.94 GPixel/s, and a far higher texture rate at 900.9 GTexel/s versus 266.2 GTexel/s.

These raw throughput advantages do not translate into recorded benchmark wins because no N1X 48SM scores exist in the database. The wins counter shows zero for both cards in head-to-head tests. The RTX PRO 2000's benchmark suite covers DirectX 9 through 12, OpenCL, Vulkan, and general 2D/3D workloads, while the IGP has no measured scores to compare.

The Verdict

The data points to a clear split: the RTX PRO 2000 Blackwell is the only one of the two with measurable, recorded performance in the database, and it holds a 70th percentile rank versus the N1X 48SM's 50th percentile. The discrete card also brings full API support with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it usable across standard workstation and graphics workloads. The N1X 48SM lists N/A for all APIs, which limits its applicability to systems where the IGP's integrated nature is sufficient.

For users needing a drop-in discrete workstation GPU with proven benchmark results, the RTX PRO 2000 is the only option with data. Its nearest rivals show it is competitive, sitting within 1.8% of three different cards and ahead of the RTX A5000 Mobile by 2.0%. The 70 W TDP, dual-slot footprint, and four mini-DisplayPort 2.1b outputs suit a conventional workstation build.

The N1X 48SM, despite higher theoretical FP32 throughput, larger memory pool, and greater texture and pixel rates, has no benchmark scores to validate those specifications. Its 50th percentile ranking and absence of API support suggest it is not intended for the same discrete GPU roles. The RTX PRO 2000's 16 GB GDDR7 memory with 288.0 GB/s bandwidth, while smaller in capacity than the N1X's 128 GB LPDDR5X, delivers more bandwidth and comes with a full software stack.

The verdict from the recorded data: the RTX PRO 2000 Blackwell is the validated performer with a measurable benchmark presence, while the N1X 48SM remains a specification-only entity. Users requiring confirmed performance numbers should choose the RTX PRO 2000.

Where Each One Wins

The RTX PRO 2000 Blackwell wins in every category where measured data exists. It has a 70th percentile rank versus 50th, an average benchmark score of 25,269 versus zero, and full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support. Its 288.0 GB/s memory bandwidth exceeds the N1X 48SM's 273.2 GB/s, and its higher 982 MHz base clock provides a stronger low-load baseline. The four mini-DisplayPort 2.1b outputs make it suitable for multi-display workstation setups, and its 70 W TDP with a 250 W suggested PSU fits standard desktop power budgets.

The N1X 48SM wins on raw theoretical compute specifications. Its 28.83 TFLOPS FP32 is 69% higher than the RTX PRO 2000's 17.03 TFLOPS, and its texture rate of 900.9 GTexel/s is more than triple the 266.2 GTexel/s of the discrete card. The 128 GB LPDDR5X memory pool dwarfs the 16 GB GDDR7 capacity, and the 256-bit bus versus 128-bit provides a wider path, even though bandwidth is lower. The N1X also has more shading units (6,144 versus 4,352), more TMUs (384 versus 136), more RT cores (48 versus 34), and more tensor cores (192 versus 136). Its 2346 MHz boost clock is higher than the RTX PRO 2000's 1957 MHz, and its pixel rate of 112.6 GPixel/s beats 93.94 GPixel/s.

The PCIe 5.0 x16 interface on the N1X 48SM provides double the lane width of the RTX PRO 2000's x8 connection. The IGP's integrated nature means no slot occupancy and no power connectors, which suits compact or unified designs. The later release date of 2026-05-31 suggests a newer product generation, though the RTX PRO 2000 released 2025-08-10 remains Active.

For use cases demanding confirmed performance, API compatibility, and multi-output display connectivity, the RTX PRO 2000 is the data-backed choice. For scenarios where raw compute throughput, massive memory capacity, and integrated packaging matter more than measured benchmarks, the N1X 48SM holds the specification advantage. The database records no wins for either card in head-to-head tests, so these distinctions come entirely from the available specification and benchmark data.
