NVIDIA N1 20SM vs NVIDIA RTX PRO 6000 Blackwell Server Comparison

Head-to-Head Benchmarks

The database records no direct benchmark comparisons between the NVIDIA N1 20SM and the NVIDIA RTX PRO 6000 Blackwell Server. The head-to-head benchmark table is empty, and neither product has a win count against the other. This is a common situation when one product is an integrated graphics processor (IGP) and the other is a dedicated server accelerator; their intended workloads rarely overlap in standardized testing.

For the RTX PRO 6000 Blackwell Server, the sole recorded benchmark result comes from the 3DMark Steel Nomad DX12 test, where it scores 5996 points. This places it at the 34th percentile among all GPUs in the database. Its nearest rivals in that test are the NVIDIA GeForce GTX 770M (average score 6000, delta of -0.1%), the AMD Radeon RX 6400 (average score 6001, delta of -0.1%), the AMD FirePro W4100 (average score 5987, delta of 0.2%), and the NVIDIA Quadro K4000M (average score 5986, delta of 0.2%). These deltas are all within a fraction of a percent, meaning the RTX PRO 6000 sits essentially at parity with those older or lower-tier cards in this specific synthetic workload, despite its vastly larger compute resources.

The N1 20SM has no benchmarks recorded in the database, and its average benchmark score is zero. Its percentile versus all GPUs is 50, which is a neutral midpoint, but without any actual test scores, that percentile carries no comparative weight. The data simply does not allow a numerical head-to-head comparison between these two parts.

The Verdict

The recorded data makes the selection straightforward for different use cases. The RTX PRO 6000 Blackwell Server is the only one of the two with any measured benchmark output, and its specifications dwarf the N1 20SM in nearly every compute metric. The RTX PRO 6000 delivers 126.0 TFLOPS of FP32 performance versus 12.01 TFLOPS for the N1 20SM, a 10.5x advantage in raw floating-point throughput. Its texture rate is 1,968.0 GTexel/s compared to 375.4 GTexel/s, and its pixel rate is 502.5 GPixel/s versus 56.30 GPixel/s.

The N1 20SM is an integrated graphics processor, meaning it shares a package with a CPU and uses system memory. It has no dedicated video memory; it uses 128 GB of LPDDR5X on a 256-bit bus, delivering 273.2 GB/s of bandwidth. The RTX PRO 6000 has 96 GB of GDDR7 on a 512-bit bus, delivering 1.79 TB/s, which is roughly 6.5x the memory bandwidth of the N1 20SM.

For anyone building a server that needs maximum compute density, the RTX PRO 6000 Blackwell Server is the clear choice from the data. It is a dual-slot card with a 600 W TDP, requires a 1000 W power supply, uses a single 16-pin power connector, and has four DisplayPort 2.1b outputs. The N1 20SM uses no power connectors at all, is an IGP, and has a single HDMI output. These are fundamentally different products: one is a discrete accelerator, the other is an integrated solution for systems where a separate card is not an option.

Architecture Differences

Both processors share the Blackwell 2.0 architecture and are manufactured on TSMC's 5 nm process, but their physical designs diverge sharply. The N1 20SM uses the GB20B chip with a die size of 382 mm², while the RTX PRO 6000 Blackwell Server uses the GB202 chip with a die size of 750 mm², nearly double the area. The transistor count for the N1 20SM is listed as unknown, while the RTX PRO 6000 has 92,200 million transistors, yielding a transistor density of 122.9 million per mm².

The RTX PRO 6000 carries 24,064 shading units, 752 texture mapping units, and 192 ROPs. The N1 20SM has 2,560 shading units, 160 TMUs, and only 24 ROPs. Ray tracing cores number 188 on the RTX PRO 6000 versus 20 on the N1 20SM, and tensor cores number 752 versus 80. The RTX PRO 6000 also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the N1 20SM lists N/A for all three API categories, indicating no support for those graphics APIs.

Clock speeds differ as well. The N1 20SM has a base clock of 741 MHz and a boost clock of 2346 MHz. The RTX PRO 6000 runs at a base of 1590 MHz and boosts to 2617 MHz. Memory clocks are 1067 MHz (8.5 Gbps effective) for the N1 20SM and 1750 MHz (28 Gbps effective) for the RTX PRO 6000. The N1 20SM belongs to the "Blackwell IGP (N1x)" generation, while the RTX PRO 6000 belongs to the "Server Blackwell (Bxx)" generation.

Where Each One Wins

The RTX PRO 6000 Blackwell Server wins across every measurable compute specification. Its FP32 throughput of 126.0 TFLOPS, FP16 throughput of 126.0 TFLOPS, texture rate of 1,968.0 GTexel/s, and pixel rate of 502.5 GPixel/s are all far above the N1 20SM's corresponding figures of 12.01 TFLOPS, 12.01 TFLOPS, 375.4 GTexel/s, and 56.30 GPixel/s. It also has 188 ray tracing cores versus 20, and 752 tensor cores versus 80. The RTX PRO 6000 has a larger die, a higher transistor count, and a higher memory bandwidth of 1.79 TB/s.

The N1 20SM wins in specific form-factor and capacity areas. It is an integrated graphics processor, requiring no power connectors and no separate slot, whereas the RTX PRO 6000 is a dual-slot card with a 600 W TDP and a 1000 W power supply recommendation. The N1 20SM offers 128 GB of memory, which is 32 GB more than the RTX PRO 6000's 96 GB. It also has a smaller die at 382 mm² compared to 750 mm², which suggests a lower physical footprint for integrated use cases. The N1 20SM's release date is later in the database (2026-05-31) compared to the RTX PRO 6000's release date (2025-03-17), making it the more recent product.

For a system that cannot accommodate a discrete card, the N1 20SM is the only option of the two. For any workload that demands maximum compute, memory bandwidth, or graphics API support, the RTX PRO 6000 is unequivocally the stronger part.
