NVIDIA B200 SXM6 vs NVIDIA GeForce RTX 5070 SUPER Comparison

NVIDIA B200 SXM6 is a server accelerator built on the GB100 chip with a 5 nm process and 208,000 million transistors. NVIDIA GeForce RTX 5070 SUPER is a consumer graphics card on the GB205 chip, also 5 nm, with 31,100 million transistors. The two devices share a manufacturer and process node but diverge sharply in every other measurable category. The database records no head-to-head benchmark entries for this pair, so the following analysis relies on the individual recorded metrics, the RTX 5070 SUPER’s single 3DMark Steel Nomad DX12 score, and the percentile rankings assigned to each unit.

Head-to-Head Benchmarks

The B200 SXM6 carries no benchmark entries in the database, leaving its performance profile defined entirely by its theoretical throughput figures. The RTX 5070 SUPER has one recorded benchmark result: a 3DMark Steel Nomad DX12 score of 2690. That score places the card at the 18th percentile among all GPUs in the database. Its nearest rivals are the NVIDIA Quadro K1100M with an average score of 2664 and a delta of 1%, the NVIDIA GeForce GT 1030 at 2662 with a delta of 1.1%, the Intel Arc Pro B50 at 2660 with a delta of 1.1%, and the NVIDIA GeForce GT 440 at 2645 with a delta of 1.7%. The RTX 5070 SUPER leads its closest competitor by roughly 26 points, which translates to about a 1% margin. That is a narrow advantage, and the data indicates the card sits in a cluster of low-to-midrange performers rather than at the top of the distribution.

The B200 SXM6 has no comparable frame-based benchmark, but its compute specifications suggest a different class of workload. The B200 SXM6 delivers 69.34 TFLOPS of FP32 performance, while the RTX 5070 SUPER delivers 32.15 TFLOPS. That gap of 37.19 TFLOPS means the B200 SXM6 operates at roughly 2.16 times the FP32 throughput of the RTX 5070 SUPER. In FP16, both devices show a 1:1 ratio with their FP32 numbers, so the B200 SXM6 again reaches 69.34 TFLOPS versus 32.15 TFLOPS on the RTX 5070 SUPER. Texture fill rates follow a similar pattern: the B200 SXM6 achieves 1,083.4 GTexel/s, whereas the RTX 5070 SUPER reaches 502.4 GTexel/s. The B200 SXM6’s texture rate is more than double that of the RTX 5070 SUPER.

Pixel throughput tells a different story. The RTX 5070 SUPER manages 201.0 GPixel/s, while the B200 SXM6 records 43.92 GPixel/s. The RTX 5070 SUPER is approximately 4.6 times faster in pixel fill rate. This divergence reflects the fundamental design goals of each chip. The B200 SXM6 is built for compute density and memory bandwidth, not rasterization output. The RTX 5070 SUPER, as a consumer graphics card, prioritizes pixel processing for display rendering. The B200 SXM6 has 24 ROPs, while the RTX 5070 SUPER has 80 ROPs, which explains the pixel rate difference. In vertex or geometry throughput, the B200 SXM6’s 1,083.4 GTexel/s versus 502.4 GTexel/s on the RTX 5070 SUPER indicates the server part sustains higher texture work, but the RTX 5070 SUPER’s ROP count gives it a clear advantage in final pixel output.

Memory bandwidth is another major separator. The B200 SXM6 uses 180 GB of HBM3e on an 8192-bit bus, achieving 8.19 TB/s. The RTX 5070 SUPER uses 18 GB of GDDR7 on a 192-bit bus, reaching 672.0 GB/s. The B200 SXM6’s bandwidth is 12.2 times higher. This massive delta aligns with the B200’s server positioning, where large datasets and tensor workloads demand rapid data movement. The RTX 5070 SUPER’s memory speed of 1750 MHz with 28 Gbps effective is higher per pin, but the narrow bus width limits aggregate throughput.

The B200 SXM6 has 18,944 shading units, 592 TMUs, and 592 tensor cores. The RTX 5070 SUPER has 6,400 shading units, 200 TMUs, and 200 tensor cores. The B200 SXM6’s shading unit count is 2.96 times that of the RTX 5070 SUPER. Tensor core counts also favor the B200 SXM6 by a factor of 2.96. The RTX 5070 SUPER does include 50 RT cores, a feature the B200 SXM6 lacks entirely, as its RT core field is null. Clock speeds differ substantially: the B200 SXM6 has a base clock of 120 MHz and a boost of 1830 MHz, while the RTX 5070 SUPER runs at 2325 MHz base and 2512 MHz boost. The RTX 5070 SUPER’s boost clock is 682 MHz higher, or about 37% faster, yet the B200 SXM6 still wins on raw throughput due to its wider execution resources.

The Verdict

From the recorded data, the B200 SXM6 is the correct choice for compute-bound tasks that rely on FP32, FP16, tensor operations, or memory bandwidth. Its 69.34 TFLOPS FP32 output, 8.19 TB/s bandwidth, and 180 GB capacity position it as a server-grade accelerator. The RTX 5070 SUPER, with its 32.15 TFLOPS FP32 and 672.0 GB/s bandwidth, covers a fraction of that compute envelope. The B200 SXM6’s 592 tensor cores versus 200 on the RTX 5070 SUPER reinforces this separation. The RTX 5070 SUPER’s only clear wins in the data are pixel rate, ROP count, and clock speed. The 201.0 GPixel/s pixel rate and 80 ROPs make it suitable for rasterized graphics output, something the B200 SXM6 cannot do at all because it has no display outputs.

The RTX 5070 SUPER’s benchmark score of 2690 places it at the 18th percentile, with its nearest rivals all within a 1.7% delta. That clustering shows the card delivers performance comparable to older or lower-tier parts in the database, not a top-tier result. The B200 SXM6 sits at the 50th percentile but has no benchmark score, so that percentile reflects its position among all GPUs without a measured workload. Users requiring a display-capable graphics card with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support must choose the RTX 5070 SUPER, as the B200 SXM6 lists N/A for all three APIs. Users requiring maximum compute and memory throughput for server deployments should select the B200 SXM6, despite its 1000 W TDP and 1400 W suggested PSU.

Architecture Differences
