NVIDIA B200 SXM6 vs NVIDIA GeForce RTX 5070 Mobile Comparison

Head-to-Head Benchmarks

The database contains no shared benchmark scores between the NVIDIA B200 SXM6 and the NVIDIA GeForce RTX 5070 Mobile. The B200 SXM6 has no recorded benchmark entries, while the RTX 5070 Mobile has nine recorded tests. This absence of overlapping measurements prevents any direct numerical comparison of application performance. The B200 SXM6 shows an average benchmark score of zero and a percentile rank of 50 among all GPUs, while the RTX 5070 Mobile achieves an average benchmark score of 29,928 and sits in the 75th percentile.

The RTX 5070 Mobile's recorded scores span multiple API workloads. In Geekbench OpenCL, it scores 122,238, and in Geekbench Vulkan, it scores 116,960. Passmark results show a DirectX 10 score of 129, DirectX 11 score of 192, DirectX 12 score of 93, and DirectX 9 score of 214. The 2D graphics test yields 896, the 3D graphics test yields 20,355, and the GPU compute test yields 8,279. These figures establish a baseline for the mobile part but offer no comparison point for the server accelerator.

The B200 SXM6's theoretical specifications indicate an entirely different performance class. Its FP32 throughput is 69.34 TFLOPS, while the RTX 5070 Mobile delivers 13.13 TFLOPS. Pixel rate differs as well: the B200 SXM6 achieves 43.92 GPixel/s versus 68.40 GPixel/s for the RTX 5070 Mobile. Texture rate heavily favors the server part at 1,083.4 GTexel/s compared to 205.2 GTexel/s. The B200 SXM6 also carries 18,944 shading units, 592 TMUs, and 592 tensor cores, while the RTX 5070 Mobile has 4,608 shading units, 144 TMUs, and 144 tensor cores. The RTX 5070 Mobile counters with 48 ROPs against the B200 SXM6's 24 ROPs, and it includes 36 RT cores while the B200 SXM6 lists none.

Memory capacity and bandwidth show a massive separation. The B200 SXM6 uses 180 GB of HBM3e across an 8192-bit bus, delivering 8.19 TB/s of bandwidth. The RTX 5070 Mobile uses 8 GB of GDDR7 over a 128-bit bus, providing 384.0 GB/s. That difference places the server accelerator roughly 21 times ahead in raw memory bandwidth based on the recorded figures. The B200 SXM6's memory clock is listed as 2000 MHz with 8 Gbps effective, while the RTX 5070 Mobile runs 1500 MHz with 24 Gbps effective, reflecting different memory technologies rather than comparable clock rates.

Nearest rival data exists only for the RTX 5070 Mobile. Its average score of 29,928 sits 0.1% below the NVIDIA GeForce RTX 3070 Ti at 29,945, 0.5% above the NVIDIA GeForce RTX 2080 Ti at 29,783, 0.6% below the AMD Radeon RX 6800 at 30,095, and 1.7% below the AMD Radeon RX 6700 at 30,433. The B200 SXM6 has no nearest rivals listed, so no relative positioning is available from the database.

Where Each One Wins

The RTX 5070 Mobile wins in any scenario where benchmark scores matter, because it is the only part with recorded measurements. It wins on pixel rate, producing 68.40 GPixel/s against the B200 SXM6's 43.92 GPixel/s, and it wins on ROP count with 48 versus 24. It also supports a full API stack: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the B200 SXM6 lists N/A for all three. For graphics workloads that rely on rasterization output, ray tracing, or modern API features, the RTX 5070 Mobile is the functional choice.

The B200 SXM6 wins on raw compute throughput and memory resources. Its FP32 and FP16 figures both reach 69.34 TFLOPS with 1:1 ratio, compared to 13.13 TFLOPS for the RTX 5070 Mobile. Its texture rate of 1,083.4 GTexel/s vastly exceeds the mobile part's 205.2 GTexel/s. The 180 GB memory capacity and 8.19 TB/s bandwidth dwarf the 8 GB and 384.0 GB/s of the RTX 5070 Mobile. The B200 SXM6 also has more shading units, TMUs, and tensor cores, and its transistor count of 208,000 million versus 21,900 million reflects a much larger implementation.

The B200 SXM6 targets server workloads where memory bandwidth and tensor throughput dominate, while the RTX 5070 Mobile targets portable graphics where API support, pixel output, and power efficiency matter. The B200 SXM6's 1000 W TDP and 1400 W suggested PSU indicate a stationary, high-power installation, whereas the RTX 5070 Mobile's 50 W TDP and integrated form factor suit battery-powered devices. The B200 SXM6 has no display outputs, while the RTX 5070 Mobile's outputs are listed as portable device dependent.

The Verdict

The data supports a clear split by use case. For any standard graphics benchmark, the RTX 5070 Mobile is the only option with recorded scores, and its 75th percentile ranking places it above the B200 SXM6's 50th percentile. Its nearest rivals show it trading within 1.7% of several desktop-class GPUs, which indicates competitive performance for a mobile part. The RTX 5070 Mobile's 122,238 OpenCL score and 116,960 Vulkan score demonstrate substantial compute capability for a 50 W integrated part.

For server-scale compute, the B200 SXM6's specifications point to a different category entirely. Its 69.34 TFLOPS FP32 output, 8.19 TB/s memory bandwidth, and 180 GB capacity are orders of magnitude beyond the mobile part. The 208,000 million transistors on a 1628 mm² die versus 21,900 million on 181 mm² show the physical scale difference. The B200 SXM6's launch MSRP of 34,999 USD reflects its enterprise positioning, though the RTX 5070 Mobile has no listed launch MSRP.

Neither part replaces the other. The RTX 5070 Mobile delivers measured performance with modern graphics APIs and ray tracing support, while the B200 SXM6 provides unmatched memory bandwidth and tensor throughput for non-graphics workloads. Users needing a graphics card for standard rendering should choose the RTX 5070 Mobile based on its benchmark record. Users needing a compute accelerator for large-scale data processing should choose the B200 SXM6 based on its specification sheet.
