NVIDIA B200 SXM6 vs NVIDIA GeForce RTX 5080 SUPER Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the NVIDIA B200 SXM6 and the NVIDIA GeForce RTX 5080 SUPER. The B200 SXM6 has no recorded benchmark scores, while the RTX 5080 SUPER has a single entry: a 3DMark Steel Nomad DX12 score of 3075. This score places the RTX 5080 SUPER at the 19th percentile among all GPUs in the database, a modest position that reflects its recorded performance in that specific test.

The RTX 5080 SUPER's 3075 score sits within a narrow band of comparable results. It trails the NVIDIA Quadro P1000 by 2.8%, which scores 3163, and the Intel Arc Pro B60 by 3.4%, which scores 3182. Conversely, it leads the NVIDIA GeForce 820A by 3.1%, which scores 2983, and the NVIDIA GeForce GTX 860M by 3.6%, which scores 2967. These deltas are small, indicating that in this particular benchmark, the RTX 5080 SUPER performs near the middle of a cluster of very different products, from professional workstation cards to older mobile GPUs.

The B200 SXM6, by contrast, has no benchmark entries and an average benchmark score of zero. Its percentile versus all GPUs is listed at 50, but this figure is derived from missing data rather than measured results. The head-to-head wins counters show zero for both products, confirming that no direct comparative testing exists in the database.

Where Each One Wins

Without head-to-head benchmark data, wins must be inferred from architectural and specification differences recorded in the database. The B200 SXM6 dominates in raw compute throughput. Its FP32 performance is 69.34 TFLOPS, and its FP16 performance is also 69.34 TFLOPS at a 1:1 ratio. The RTX 5080 SUPER delivers 56.28 TFLOPS in both FP32 and FP16, also at 1:1. This gives the B200 SXM6 a 23.2% advantage in floating-point throughput, a meaningful lead for workloads that scale with raw shader compute, such as large-scale simulation or dense matrix operations.

The B200 SXM6 also holds a decisive lead in memory capacity and bandwidth. It carries 180 GB of HBM3e memory across an 8192-bit bus, yielding 8.19 TB/s of bandwidth. The RTX 5080 SUPER has 24 GB of GDDR7 memory on a 256-bit bus, providing 1.02 TB/s. The B200 SXM6 offers 7.5 times the memory capacity and roughly 8 times the bandwidth. For datasets that exceed 24 GB, such as large language model inference or massive scientific datasets, the B200 SXM6 is the only viable option between these two.

The RTX 5080 SUPER wins in several areas that matter for client-side graphics. Its pixel rate is 293.1 GPixel/s, compared to 43.92 GPixel/s for the B200 SXM6, a 6.7 times advantage. Its texture rate is 879.3 GTexel/s versus 1,083.4 GTexel/s, so the B200 SXM6 leads in texture throughput by 23.2%, but the RTX 5080 SUPER has dedicated ray tracing cores (84 of them) while the B200 SXM6 lists no RT cores at all. The RTX 5080 SUPER also supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the B200 SXM6 reports N/A for all three APIs. The RTX 5080 SUPER includes display outputs (1x HDMI 2.1b, 3x DisplayPort 2.1b), while the B200 SXM6 has no outputs.

Architecture Differences

Both GPUs use TSMC's 5 nm process node and NVIDIA's Blackwell architecture family, but they diverge significantly in implementation. The B200 SXM6 uses the GB100 chip, belongs to the Server Blackwell (Bxx) generation, and is manufactured with 208,000 million transistors on a 1628 mm² die. Its transistor density is 127.8 million per mm². The RTX 5080 SUPER uses the GB203 chip, belongs to the GeForce 50 generation, and packs 45,600 million transistors onto a 378 mm² die, giving a density of 120.6 million per mm². The B200 SXM6 has 4.6 times the transistor count and a die area 4.3 times larger, though the density figures are close.

The B200 SXM6 is built as a server module with a slot width of "SXM Module" and a PCIe 6.0 x16 interface. It has no power connector listed and no display outputs. Its TDP is 1000 W, and its suggested PSU is 1400 W. The RTX 5080 SUPER is a dual-slot consumer card with a PCIe 5.0 x16 interface, a single 16-pin power connector, and a TDP of 415 W. It measures 304 mm in length, 137 mm in height, and 40 mm in width.

The B200 SXM6 has 18,944 shading units, 592 TMUs, and only 24 ROPs. The RTX 5080 SUPER has 10,752 shading units, 336 TMUs, and 112 ROPs. The B200 SXM6's ROP count is strikingly low for its shader count, which explains its low pixel rate relative to its FP32 throughput. The B200 SXM6 has 592 tensor cores, while the RTX 5080 SUPER has 336 tensor cores. The RTX 5080 SUPER adds 84 RT cores. Memory clocks differ: the B200 SXM6 runs at 2000 MHz with 8 Gbps effective, while the RTX 5080 SUPER runs at 2000 MHz with 32 Gbps effective, the higher data rate compensating for the narrower bus.

The B200 SXM6 was released on 2024-10-31, while the RTX 5080 SUPER is dated 2025-12-31. The B200 SXM6 lists its predecessor as "Server Hopper" and successor as "Server Rubin," while the RTX 5080 SUPER has no predecessor or successor recorded. Both are marked as Active in production status.

The Verdict

The recorded data supports a clear split by intended use. The NVIDIA B200 SXM6 is a server accelerator with overwhelming memory resources: 180 GB of HBM3e, 8.19 TB/s bandwidth, and an 8192-bit bus. Its FP32 and FP16 throughput of 69.34 TFLOPS exceeds the RTX 5080 SUPER's 56.28 TFLOPS, and its 592 tensor cores outnumber the RTX 5080 SUPER's 336. For compute workloads that fit in memory, the B200 SXM6 is the stronger part by every measured specification.

The RTX 5080 SUPER is a client graphics card with display outputs, full API support (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4), and dedicated ray tracing hardware. Its pixel rate of 293.1 GPixel/s is over six times the B200 SXM6's 43.92 GPixel/s, and its 112 ROPs dwarf the B200 SXM6's 24. Its 1.02 TB/s bandwidth and 24 GB capacity are far smaller, but it runs at a 415 W TDP versus 1000 W, uses a standard PCIe 5.0 x16 slot, and fits in a dual-slot 304 mm form factor. The B200 SXM6 requires an SXM module slot and a 1400 W PSU.

The RTX 5080 SUPER's single benchmark score of 3075 in 3DMark Steel Nomad DX12 places it near the Quadro P1000 and Arc Pro B60, within a few percent either way. The B200 SXM6 has no recorded benchmark, so no direct performance comparison is possible from the database. Based on specifications alone, the B200 SXM6 is the choice for large-scale compute and memory-bound workloads, while the RTX 5080 SUPER is the choice for graphics rendering, ray tracing, and any task requiring standard display output and consumer API support.

The launch MSRP for the B200 SXM6 is 34,999 USD, and for the RTX 5080 SUPER it is 999 USD. The B200 SXM6 targets server deployments where capacity and raw throughput justify its power envelope; the RTX 5080 SUPER targets client systems where pixel throughput, API compatibility, and a compact dual-slot design matter more.
