NVIDIA B200 SXM6 vs NVIDIA RTX 500 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark scores for the NVIDIA B200 SXM6 and the NVIDIA RTX 500 Mobile Ada Generation. Both products show an average benchmark score of zero, and neither has a populated list of nearest rivals. The percentile versus all GPUs is identical for both at 50, indicating no measured performance separation in the current dataset. This absence of comparative data means that any performance conclusions must be drawn strictly from their architectural specifications and recorded feature sets.

The B200 SXM6 delivers 69.34 TFLOPS of FP32 compute, while the RTX 500 Mobile Ada Generation delivers 8.294 TFLOPS. The ratio between these figures shows the server part at roughly 8.36 times the raw single-precision throughput of the mobile part. In FP16, both parts operate at a 1:1 ratio with their FP32 numbers, so the same multiple holds for half-precision workloads. Pixel throughput tells a different story: the RTX 500 achieves 64.80 GPixel/s versus 43.92 GPixel/s for the B200, meaning the mobile chip has a 47.5% advantage in pixel fill rate. Texture rate reverses the order again, with the B200 reaching 1,083.4 GTexel/s compared to 129.6 GTexel/s, a factor of 8.36 in favor of the server GPU.

Architecture Differences

The two products belong to entirely different architectural families and market segments. The B200 SXM6 uses the GB100 chip built on the Blackwell architecture, part of the Server Blackwell (Bxx) generation. The RTX 500 Mobile Ada Generation uses the AD107 chip on the Ada Lovelace architecture, part of the Ada-MW (x000A) generation. Both are fabricated by TSMC on a 5 nm process node, but the similarities end there. The B200 packs 208,000 million transistors on a 1628 mm² die, yielding a transistor density of 127.8 million per mm². The RTX 500 contains 18,900 million transistors on a 159 mm² die, with a density of 118.9 million per mm². The B200 die is roughly 10.24 times larger by area and holds about 11 times more transistors.

Memory architecture diverges sharply. The B200 uses 180 GB of HBM3e on an 8192-bit bus, producing 8.19 TB/s of bandwidth. The RTX 500 uses 4 GB of GDDR6 on a 64-bit bus, producing 128.0 GB/s. That is a 64-fold difference in bus width and a 64-fold difference in bandwidth, while capacity differs by 45 times. Memory clocks are listed as 2000 MHz for both, with the B200 at 8 Gbps effective and the RTX 500 at 16 Gbps effective, so the mobile part uses a faster per-pin data rate but a far narrower interface.

Compute resource counts show the scale gap. The B200 has 18,944 shading units, 592 TMUs, and 24 ROPs. The RTX 500 has 2,048 shading units, 64 TMUs, and 32 ROPs. The B200 therefore has 9.25 times more shaders and 9.25 times more TMUs, but only 75% of the ROP count. Tensor core counts are 592 for the B200 versus 64 for the RTX 500, a 9.25 ratio. The RTX 500 includes 16 dedicated RT cores, while the B200 lists no RT core count in the database. Clock behavior also differs: the B200 has a base clock of 120 MHz and a boost of 1830 MHz, while the RTX 500 has a base of 1485 MHz and a boost of 2025 MHz. The mobile part starts from a much higher base and boosts about 10.7% higher, but the B200 has a far larger boost multiplier over its base.

Power and physical formats are in different classes. The B200 carries a TDP of 1000 W with a suggested PSU of 1400 W, mounted as an SXM Module with PCIe 6.0 x16. The RTX 500 has a TDP of 35 W, uses no power connectors, is classified as an IGP, and connects over PCIe 4.0 x8. The B200 has no display outputs, while the RTX 500's outputs are portable device dependent. API support also separates them: the RTX 500 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the B200 lists N/A for all three. The B200 was released on 2024-10-31, and the RTX 500 on 2024-02-25. Both are listed as Active in production status. The B200's predecessor is Server Hopper and its successor is Server Rubin; the RTX 500's predecessor is Ampere-MW and its successor is Blackwell-MW. The B200 has a launch MSRP of 34,999 USD; the RTX 500 has no recorded launch MSRP.

Where Each One Wins

The B200 SXM6 wins decisively in compute-heavy workloads that scale with shader count, tensor core availability, and memory bandwidth. Its 69.34 TFLOPS FP32 throughput, 1,083.4 GTexel/s texture rate, and 8.19 TB/s memory bandwidth position it for large-scale server tasks such as training, inference, and scientific simulation. The 180 GB HBM3e capacity supports massive datasets that would never fit in the 4 GB frame buffer of the mobile part. The SXM module form factor, PCIe 6.0 x16 interface, and 1000 W TDP confirm its role as a dedicated accelerator without display functionality.

The RTX 500 Mobile Ada Generation wins in pixel-focused workloads and mobility-constrained environments. Its 64.80 GPixel/s pixel rate exceeds the B200 by 47.5%, and its 32 ROPs outnumber the B200's 24. The higher boost clock of 2025 MHz and base clock of 1485 MHz indicate better per-clock efficiency for latency-sensitive tasks. The 35 W TDP, IGP slot width, and absence of power connectors suit thin-and-light portable devices. API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 enables client-side rendering and graphics applications, which the B200 cannot handle due to its N/A API status.

The RTX 500 also has an advantage in transistor density per watt, though the database does not provide direct efficiency metrics. With 18,900 million transistors in a 35 W envelope, it delivers compute at a far lower power draw than the B200's 1000 W. The B200's density of 127.8M per mm² is only slightly above the RTX 500's 118.9M per mm², meaning the B200's advantage comes from raw scale rather than process efficiency.

The Verdict

The data shows two products with no overlapping use cases. The NVIDIA B200 SXM6 is a server accelerator built on the Blackwell architecture with 208,000 million transistors, 180 GB of HBM3e, 8.19 TB/s of bandwidth, and 69.34 TFLOPS of FP32. It has no display outputs and no graphics API support, making it unsuitable for any client-side rendering. Its 1000 W TDP and SXM form factor require a server chassis with substantial power delivery. The recorded launch MSRP is 34,999 USD.

The NVIDIA RTX 500 Mobile Ada Generation is a low-power integrated GPU for portable devices. Its 35 W TDP, IGP slot width, and absence of power connectors allow integration into laptops and compact systems. It delivers 8.294 TFLOPS FP32, 4 GB of GDDR6, and 64.80 GPixel/s, and it supports the full modern graphics API stack. Its 2,048 shading units and 16 RT cores provide adequate throughput for mobile graphics and compute tasks.

The B200 should be selected for large-scale parallel workloads where memory capacity, bandwidth, and raw compute matter more than pixel output or power efficiency. The RTX 500 should be selected for portable systems that require display output, graphics API compatibility, and low power draw. The 47.5% pixel rate advantage of the RTX 500 and its higher boost clock do not offset the B200's 8.36-fold lead in FP32 and texture rate, but those metrics are irrelevant in each product's respective market. The database records no benchmark scores for either, so these conclusions rest entirely on architectural specifications and recorded feature sets.
