NVIDIA B200 SXM6 vs NVIDIA GeForce RTX 5070 Comparison

Head-to-Head Benchmarks

The database contains no shared benchmark entries for the NVIDIA B200 SXM6 and the NVIDIA GeForce RTX 5070. The B200 SXM6 has no recorded benchmark scores, while the RTX 5070 carries a full suite of ten results. Consequently, a direct score-by-score comparison is impossible. What the data does allow is a comparison of each product’s standing within the database’s broader GPU landscape.

The RTX 5070 holds a percentile rank of 82 against all GPUs, with an average benchmark score of 40,377. Its nearest rivals, all within a 2% delta, include the AMD Radeon Pro 580 (40,318, 0.1% delta), the AMD Radeon Pro WX 7100 (40,063, 0.8% delta), and the AMD Radeon Pro 5300 (40,870, -1.2% delta). The NVIDIA RTX A500 Mobile (39,568, 2% delta) also sits close. These figures place the RTX 5070 in a tightly clustered competitive band where single-digit percentage differences separate it from comparable workstation and mobile parts.

The B200 SXM6, by contrast, has an average benchmark score of 0 and a percentile rank of 50, which is the midpoint placeholder used when no measured results exist. The data therefore shows no evidence of performance superiority for the B200 SXM6 in any benchmark test, simply because no tests were recorded. The RTX 5070 wins every head-to-head category by default, but this is a data artifact rather than a physical performance conclusion. The B200 SXM6’s theoretical specifications, such as 69.34 TFLOPS FP32 and 1,083.4 GTexel/s texture rate, suggest substantial compute capability, but the database provides no measured confirmation. Likewise, the RTX 5070’s 30.87 TFLOPS FP32 and 482.3 GTexel/s texture rate come from its specification sheet, not from the benchmark suite. The recorded results, including a 3DMark Steel Nomad DX12 score of 5,077 and a Geekbench OpenCL score of 172,660, belong exclusively to the RTX 5070.

Architecture Differences

Both chips are built by TSMC on a 5 nm process, but the similarities end there. The B200 SXM6 uses the GB100 chip under the Blackwell architecture, while the RTX 5070 uses the GB205 chip under Blackwell 2.0. The B200 SXM6 belongs to the Server Blackwell (Bxx) generation, and the RTX 5070 belongs to the GeForce 50 series. These are different product lines with divergent design goals.

The transistor counts illustrate the scale gap. The B200 SXM6 packs 208,000 million transistors on a 1,628 mm² die, yielding a transistor density of 127.8 million per mm². The RTX 5070 contains 31,100 million transistors on a 263 mm² die, with a density of 118.3 million per mm². The B200 SXM6 is roughly 6.7 times larger in die area and holds about 6.7 times more transistors. Density is slightly higher on the server part, but the real difference is sheer scale.

Memory architecture diverges sharply. The B200 SXM6 uses 180 GB of HBM3e on an 8,192-bit bus, delivering 8.19 TB/s of bandwidth. The RTX 5070 uses 12 GB of GDDR7 on a 192-bit bus, delivering 672.0 GB/s. The B200 SXM6 has 15 times the memory capacity and over 12 times the bandwidth. Clock behavior also differs: the B200 SXM6 has a base clock of 120 MHz and a boost clock of 1,830 MHz, while the RTX 5070 runs at 2,325 MHz base and 2,512 MHz boost. The RTX 5070’s boost clock is 37% higher, which reflects the consumer part’s emphasis on frequency scaling rather than raw parallel width.

Compute resources differ in kind as well as count. The B200 SXM6 has 18,944 shading units, 592 TMUs, 24 ROPs, and 592 tensor cores. The RTX 5070 has 6,144 shading units, 192 TMUs, 80 ROPs, 48 RT cores, and 192 tensor cores. The B200 SXM6 has no listed RT cores, while the RTX 5070 includes dedicated ray tracing hardware. The ROP count is reversed: the RTX 5070 has 80 ROPs versus 24 on the B200 SXM6.

The B200 SXM6 uses an SXM Module slot width and a PCIe 6.0 x16 bus interface, with no display outputs. The RTX 5070 is a dual-slot card with PCIe 5.0 x16, one HDMI 2.1b port, and three DisplayPort 2.1b outputs. API support also differs. The B200 SXM6 lists N/A for DirectX, OpenGL, and Vulkan, while the RTX 5070 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The server part is not designed for graphics rendering; the consumer part is.

The Verdict

The database records no benchmark scores for the B200 SXM6, so any verdict must rely on specification differences and the RTX 5070’s measured results. The RTX 5070 clearly serves the consumer graphics and compute market. Its average benchmark score of 40,377 places it in the 82nd percentile, with nearest rivals within a 2% delta. Its 12 GB GDDR7 memory, 48 RT cores, and full API support (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4) indicate it is built for real-time rendering, gaming, and general-purpose compute workloads that require a display output.

The B200 SXM6, with 180 GB of HBM3e, 8.19 TB/s bandwidth, and 69.34 TFLOPS FP32, targets a completely different workload class: large-scale server compute, AI training, and scientific simulation. Its 1,000 W TDP, 1,400 W suggested PSU, and lack of display outputs confirm this orientation. The B200 SXM6 has no benchmark results in the database, so its actual performance relative to the RTX 5070 cannot be quantified from recorded measurements.

For a user who needs graphics output, API support, and a compact dual-slot card, the RTX 5070 is the only functional choice. For a user who needs massive memory capacity and bandwidth in a server module, the B200 SXM6 is the only option that matches those specifications. The data does not support a performance ranking between them because the B200 SXM6 has no measured scores. The RTX 5070 wins the benchmark comparison by default, but the specification sheet shows the B200 SXM6 operates in a different performance tier entirely.

Where Each One Wins

The RTX 5070 wins in every benchmark category that the database records, because the B200 SXM6 has no entries. Looking at the RTX 5070’s individual scores, it shows strength across different test types. The 3DMark Steel Nomad DX12 result of 5,077, the Geekbench OpenCL score of 172,660, and the Geekbench Vulkan score of 178,923 all come from this consumer card. The Passmark suite shows a G3D score of 29,137 and a GPU compute score of 15,787, with lower scores in DirectX 9 (320), DirectX 10 (180), DirectX 11 (277), and DirectX 12 (108). These numbers indicate the RTX 5070 performs best in modern compute and graphics loads, not legacy API paths.

The B200 SXM6 wins on specification grounds. Its 180 GB memory capacity, 8.19 TB/s bandwidth, 69.34 TFLOPS FP32, and 1,083.4 GTexel/s texture rate all exceed the RTX 5070 by wide margins. The B200 SXM6 also has 18,944 shading units versus 6,144, and 592 tensor cores versus 192. These figures suggest it would dominate memory-bound and massively parallel workloads, though the database provides no measured proof.

The RTX 5070 wins on efficiency in the consumer context. Its 250 W TDP and 600 W suggested PSU are far lower than the B200 SXM6’s 1,000 W TDP and 1,400 W suggested PSU. The RTX 5070 also has a physical card format with dimensions of 245 mm length, 115 mm height, and 40 mm width, whereas the B200 SXM6 is an SXM module with no listed dimensions.
