NVIDIA N1X 40SM vs NVIDIA RTX PRO 6000 Blackwell Server Comparison

Head-to-Head Benchmarks

The recorded data contains only one benchmark result for the NVIDIA RTX PRO 6000 Blackwell Server: a 3DMark Steel Nomad DX12 score of 5996. The NVIDIA N1X 40SM has no benchmark entries in the database, so a direct comparison of measured performance between these two parts is not possible from the available data.

What the database does show is how the RTX PRO 6000 Blackwell Server positions against other hardware in the same benchmark. Its score of 5996 places it within 0.1% of the NVIDIA GeForce GTX 770M (6000) and the AMD Radeon RX 6400 (6001), and within 0.2% of the AMD FirePro W4100 (5987) and the NVIDIA Quadro K4000M (5986). These deltas are negligible, indicating that in this particular DX12 workload, the RTX PRO 6000 Blackwell Server performs essentially on par with those older or lower-tier parts. This is an unusual result for a server-grade GPU with the specifications listed in the database, and it likely reflects the benchmark's sensitivity to the specific workload rather than the card's overall capability.

The N1X 40SM, being an IGP (integrated graphics processor) with no benchmark scores recorded, cannot be ranked against the RTX PRO 6000 Blackwell Server in any head-to-head test. The wins counter shows 0 for both parts, confirming the absence of direct comparison data.

Architecture Differences

Both GPUs share the same fundamental architecture, Blackwell 2.0, and are fabricated by TSMC on the same 5 nm process node. The similarities end there, as the chips are built for entirely different roles.

The N1X 40SM uses the GB20B chip with a die size of 382 mm². Its transistor count is listed as unknown. This is a Blackwell IGP (N1x) generation part, designed to be integrated directly into a system rather than installed as a discrete card. It features 5120 shading units, 320 texture mapping units, 40 ROPs, 40 ray tracing cores, and 160 tensor cores. The memory subsystem consists of 128 GB of LPDDR5X on a 256-bit bus, delivering 273.2 GB/s of bandwidth. Clock speeds are modest, with a base of 741 MHz and a boost of 2346 MHz, while memory runs at 1067 MHz (8.5 Gbps effective). The pixel rate is 93.84 GPixel/s, the texture rate is 750.7 GTexel/s, and FP32/FP16 performance is rated at 24.02 TFLOPS (1:1). The N1X 40SM has no API support listed for DirectX, OpenGL, or Vulkan, and it uses a PCIe 5.0 x16 bus interface with a single HDMI output. It requires no power connectors and has no TDP figure recorded. Its slot width is listed as IGP, meaning it occupies no expansion slot.

The RTX PRO 6000 Blackwell Server uses the GB202 chip, a much larger die at 750 mm², with 92,200 million transistors and a transistor density of 122.9M per mm². This is a Server Blackwell (Bxx) generation part. It has 24,064 shading units, 752 TMUs, 192 ROPs, 188 ray tracing cores, and 752 tensor cores. Memory is 96 GB of GDDR7 on a 512-bit bus, providing 1.79 TB/s of bandwidth. Core clocks are significantly higher: 1590 MHz base and 2617 MHz boost, with memory at 1750 MHz (28 Gbps effective). Pixel rate reaches 502.5 GPixel/s, texture rate is 1,968.0 GTexel/s, and FP32/FP16 performance is 126.0 TFLOPS (1:1). The RTX PRO 6000 Blackwell Server is a dual-slot card drawing 600 W, with a single 16-pin power connector and a suggested PSU of 1000 W. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and offers four DisplayPort 2.1b outputs. Its dimensions are 267 mm in length, 111 mm in height, and 40 mm in width.

The architectural gap is stark. The RTX PRO 6000 Blackwell Server has roughly 4.7 times the shading units, 5.2 times the FP32 throughput, 5.4 times the pixel rate, and 2.6 times the texture rate of the N1X 40SM. Memory bandwidth favors the RTX PRO 6000 by a factor of 6.5, although the N1X 40SM counters with 32 GB more capacity. The N1X 40SM's LPDDR5X is a low-power memory type suited for integration, while the RTX PRO 6000's GDDR7 is a high-bandwidth discrete solution.

The Verdict

The data clearly separates these two products by role and capability. The RTX PRO 6000 Blackwell Server is a high-end discrete server card with massive compute resources, a 600 W power draw, and full API support for modern graphics workloads. The N1X 40SM is an integrated graphics solution with a much smaller chip, lower clock speeds, and no API support listed, intended for systems where a discrete card is not required.

For compute-heavy server workloads such as rendering, AI inference, or high-resolution visualization, the RTX PRO 6000 Blackwell Server is the only viable choice based on the recorded specifications. Its 126.0 TFLOPS FP32 performance, 188 ray tracing cores, and 1.79 TB/s memory bandwidth place it in a different class entirely. The single benchmark score of 5996 in Steel Nomad DX12, while oddly low relative to its specs, does not diminish its raw compute advantage.

For systems where power consumption, space, and memory capacity are priorities, the N1X 40SM offers 128 GB of LPDDR5X memory, which exceeds the RTX PRO 6000's 96 GB. The N1X 40SM also requires no power connectors and no expansion slot, making it suitable for compact or low-power designs. However, its 24.02 TFLOPS FP32 performance and 273.2 GB/s bandwidth are far below the discrete card's capabilities.

The production status for both parts is Active, and the N1X 40SM has a later release date of 2026-05-31 compared to the RTX PRO 6000 Blackwell Server's 2025-03-17. The RTX PRO 6000 Blackwell Server lists a predecessor (Server Hopper) and successor (Server Rubin), while the N1X 40SM has neither, suggesting it is a standalone IGP product.

Where Each One Wins

The N1X 40SM wins on memory capacity, offering 128 GB versus 96 GB, which matters for workloads holding very large datasets in memory. It also wins on physical integration: it is an IGP with no slot width, no power connectors, and a single HDMI output, making it suitable for systems where a discrete card cannot fit. Its 5 nm process node and TSMC fabrication match the RTX PRO 6000, but its 382 mm² die is far smaller, which typically translates to lower manufacturing cost and power draw, though no TDP is recorded.

The RTX PRO 6000 Blackwell Server wins in every raw compute metric. Its 24,064 shading units, 752 TMUs, 192 ROPs, 188 ray tracing cores, and 752 tensor cores dwarf the N1X 40SM's 5120, 320, 40, 40, and 160 respectively. Its boost clock of 2617 MHz exceeds the N1X 40SM's 2346 MHz, and its base clock of 1590 MHz more than doubles the N1X 40SM's 741 MHz. The RTX PRO 6000 also wins on display outputs with four DisplayPort 2.1b connections versus a single HDMI. It has a full API stack, while the N1X 40SM has none listed. The RTX PRO 6000's 1.79 TB/s bandwidth is a decisive advantage for memory-intensive server tasks.

The single benchmark result for the RTX PRO 6000 Blackwell Server, 5996 in Steel Nomad DX12, places it near the GTX 770M and RX 6400 in that specific test, but this should not be read as a general performance indicator given its far superior specifications. The N1X 40SM has no comparable data, so its real-world performance cannot be assessed from the database.
