NVIDIA B200 SXM6 vs NVIDIA RTX 5000 Mobile Ada Generation Comparison

Where Each One Wins

The benchmark database shows a sharp split in capabilities between these two NVIDIA GPUs. The NVIDIA B200 SXM6 is a server-oriented accelerator with no recorded benchmark scores in the database, meaning it has zero wins in the head-to-head comparison. The NVIDIA RTX 5000 Mobile Ada Generation, in contrast, has a recorded 3DMark Steel Nomad DX12 score of 3596, giving it the sole win in the direct comparison.

The B200 SXM6 is designed for compute workloads that do not rely on traditional graphics benchmarks. Its lack of any display outputs, absence of DirectX, OpenGL, and Vulkan API support, and its SXM module form factor all point to a device intended for data center deployment rather than workstation or gaming use. The RTX 5000 Mobile, with its 12 Ultimate DirectX support, OpenGL 4.6, and Vulkan 1.4, is a mobile graphics processor capable of running standard graphics applications and APIs.

The percentile rankings reinforce this divide. The B200 SXM6 sits at the 50th percentile among all GPUs in the database, while the RTX 5000 Mobile sits at the 21st percentile. However, these percentiles must be interpreted carefully. The B200 has an average benchmark score of zero because no benchmarks have been recorded for it, which places it in the middle of the distribution by default rather than by measured performance. The RTX 5000 Mobile's 21st percentile reflects its actual measured score of 3596 in the Steel Nomad test.

The nearest rivals for the RTX 5000 Mobile provide context for its measured performance. The NVIDIA GeForce GT 545 scores 3594, a delta of just 0.1% above the RTX 5000 Mobile. The NVIDIA GeForce GT 735M scores 3616, which is 0.6% higher. The NVIDIA GeForce GTX 1050 scores 3629, 0.9% higher. The AMD Radeon HD 6770 scores 3649, 1.5% higher. These deltas are all within a narrow band, indicating that the RTX 5000 Mobile's Steel Nomad result places it in a cluster of older and less powerful GPUs in this specific test.

Architecture Differences

The two GPUs share a manufacturing process, both built on a 5 nm node at TSMC, but they diverge sharply in every other architectural aspect. The B200 SXM6 uses the GB100 chip under the Blackwell architecture, while the RTX 5000 Mobile uses the AD103 chip under the Ada Lovelace architecture. The B200 belongs to the Server Blackwell generation, and the RTX 5000 Mobile belongs to the Ada-MW generation.

Transistor counts separate these chips by an order of magnitude. The B200 SXM6 contains 208,000 million transistors on a die size of 1628 mm², yielding a transistor density of 127.8 million transistors per square millimeter. The RTX 5000 Mobile contains 45,900 million transistors on a die size of 379 mm², yielding a density of 121.1 million transistors per square millimeter. The B200's die is more than four times larger in area and holds more than four times the transistor count.

Memory architecture also differs fundamentally. The B200 SXM6 uses 180 GB of HBM3e memory on an 8192-bit bus, delivering 8.19 TB/s of bandwidth. The RTX 5000 Mobile uses 16 GB of GDDR6 memory on a 256-bit bus, delivering 576.0 GB/s of bandwidth. The B200's memory bandwidth is more than fourteen times higher, and its capacity is more than eleven times larger.

Compute resources follow a similar pattern. The B200 SXM6 has 18,944 shading units, 592 texture mapping units, and 24 raster output units. The RTX 5000 Mobile has 9,728 shading units, 304 texture mapping units, and 112 raster output units. The B200 has roughly double the shading units and texture units, but the RTX 5000 Mobile has more than four times the raster output units. The B200 has 592 tensor cores, while the RTX 5000 Mobile has 304 tensor cores. The RTX 5000 Mobile also includes 76 ray tracing cores, a feature the B200 does not list.

Clock behavior differs substantially. The B200 SXM6 runs at a base clock of 120 MHz and a boost clock of 1830 MHz. The RTX 5000 Mobile runs at a base clock of 1425 MHz and a boost clock of 2115 MHz. The RTX 5000 Mobile's base clock is more than eleven times higher, and its boost clock is about 15% higher. Memory clocks also differ, with the B200 operating at 2000 MHz (8 Gbps effective) and the RTX 5000 Mobile at 2250 MHz (18 Gbps effective).

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparisons between the B200 SXM6 and the RTX 5000 Mobile. The B200 has an empty benchmarks array and an average benchmark score of zero. The RTX 5000 Mobile has a single recorded benchmark: 3DMark Steel Nomad DX12 with a score of 3596. This score is the only quantitative performance figure available in the comparison.

The RTX 5000 Mobile's score of 3596 places it marginally ahead of the NVIDIA GeForce GT 545, which scores 3594, a delta of 0.1%. It sits slightly behind the NVIDIA GeForce GT 735M at 3616, a delta of -0.6%, and the NVIDIA GeForce GTX 1050 at 3629, a delta of -0.9%. The AMD Radeon HD 6770 leads this cluster with 3649, a delta of -1.5% relative to the RTX 5000 Mobile.

The B200 SXM6's theoretical compute rates are far higher than the RTX 5000 Mobile's measured performance suggests. The B200 delivers 69.34 TFLOPS for both FP32 and FP16 with a 1:1 ratio. The RTX 5000 Mobile delivers 41.15 TFLOPS for both FP32 and FP16, also at a 1:1 ratio. The B200's FP32 throughput is about 68% higher. Texture and pixel rates follow different patterns. The B200 achieves 1,083.4 GTexel/s in texture rate versus 643.0 GTexel/s for the RTX 5000 Mobile, a 68% advantage. The RTX 5000 Mobile, however, achieves 236.9 GPixel/s in pixel rate versus 43.92 GPixel/s for the B200, a more than fivefold advantage.

Raster output units explain the pixel rate gap. The RTX 5000 Mobile has 112 ROPs versus 24 on the B200. The B200's architecture prioritizes tensor and shading throughput over rasterization, consistent with its server positioning. The RTX 5000 Mobile's higher ROP count and pixel rate indicate a design that still accommodates traditional graphics rendering.

The Verdict

The data indicates that these two GPUs serve entirely different purposes and should not be selected against each other for the same workload. The B200 SXM6 is a server accelerator with no display outputs, no graphics API support, and no recorded benchmark scores. Its 180 GB of HBM3e memory, 8.19 TB/s bandwidth, and 69.34 TFLOPS FP32 throughput position it for large-scale compute tasks where memory capacity and bandwidth dominate. Its 1000 W TDP and 1400 W suggested PSU further confirm its data center orientation.

The RTX 5000 Mobile Ada Generation is a mobile graphics processor with full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support. Its 16 GB GDDR6 memory and 576.0 GB/s bandwidth are modest by comparison, but its 236.9 GPixel/s pixel rate and 112 ROPs make it suitable for graphics rendering. Its 120 W TDP and IGP form factor suit portable devices.

For users running graphics applications that rely on DirectX, OpenGL, or Vulkan, the data shows the RTX 5000 Mobile is the only viable option, as the B200 SXM6 lacks these APIs entirely. For compute workloads that use CUDA or other non-graphics interfaces and require massive memory capacity, the B200 SXM6's specifications indicate it is the appropriate choice. The RTX 5000 Mobile's nearest rivals in the database are older desktop and mobile GPUs, which suggests that its measured Steel Nomad performance is not competitive with modern high-end parts in that specific test.

The absence of any recorded benchmarks for the B200 SXM6 means the database cannot confirm its real-world performance relative to the RTX 5000 Mobile. The specifications, however, show vastly different design goals. The B200's launch MSRP is 34,999 USD, stated here once for reference.
