NVIDIA B300 SXM6 AC vs NVIDIA RTX 2000 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The recorded database contains only one benchmark score for the NVIDIA B300 SXM6 AC, while the NVIDIA RTX 2000 Mobile Ada Generation has no recorded benchmark entries. This makes a direct numerical comparison impossible for most workloads, but the available data still offers a clear verdict.

The B300 SXM6 AC delivers a Geekbench OpenCL score of 369,831. This places it at the 100th percentile among all GPUs in the database, meaning it outperforms every other recorded graphics processor. Its nearest rival, the NVIDIA B200, averages 345,482 points, which is 7% lower. The NVIDIA H200 NVL sits 10.4% behind with 334,891 points, the AMD Instinct MI300X trails by 16.3% with 317,994 points, and the NVIDIA L40S is 25% behind with 295,763 points. These margins show a consistent lead over the closest competitors, not a narrow edge.

The RTX 2000 Mobile Ada Generation, by contrast, has an average benchmark score of zero and a percentile ranking of 50. With no recorded OpenCL result, the database cannot confirm its compute performance in this specific test. The absence of data does not indicate failure, but it means the mobile GPU cannot be positioned against the B300 SXM6 AC in any measured workload.

What can be stated directly: the B300 SXM6 AC produces 76.99 TFLOPS of FP32 compute and 76.99 TFLOPS of FP16 compute, while the RTX 2000 Mobile Ada Generation produces 12.99 TFLOPS in both FP32 and FP16. That is a 5.9 times difference in raw compute throughput, a figure derived entirely from the recorded specifications. The B300 SXM6 AC also reaches a texture rate of 1,202.9 GTexel/s versus 203.0 GTexel/s for the mobile part, a gap of roughly 5.9 times again. Pixel rate is the one area where the smaller GPU wins on paper: the RTX 2000 Mobile Ada Generation achieves 101.5 GPixel/s, while the B300 SXM6 AC manages 48.77 GPixel/s. This is because the B300 SXM6 AC has only 24 ROPs, half the 48 ROPs found on the RTX 2000 Mobile Ada Generation, despite having far more shading units and texture mapping units.

Architecture Differences

The two GPUs come from entirely different design lineages. The B300 SXM6 AC uses the GB110 chip built on the Blackwell Ultra architecture, belonging to the Server Blackwell (Bxx) generation. The RTX 2000 Mobile Ada Generation uses the AD107 chip built on Ada Lovelace, belonging to the Ada-MW generation. Both are manufactured by TSMC on a 5 nm process, so the node is identical, but the scale diverges sharply.

The B300 SXM6 AC packs 208,000 million transistors on a 1628 mm² die, yielding a transistor density of 127.8 million per square millimeter. The RTX 2000 Mobile Ada Generation contains 18,900 million transistors on a 159 mm² die, with a density of 118.9 million per square millimeter. The server chip is over 10 times larger in die area and holds more than 11 times the transistor count. This scale difference explains the massive compute disparity.

Core configuration differs substantially. The B300 SXM6 AC carries 18,944 shading units, 592 texture mapping units, 24 ROPs, and 592 tensor cores. The RTX 2000 Mobile Ada Generation has 3,072 shading units, 96 texture mapping units, 48 ROPs, 24 ray tracing cores, and 96 tensor cores. The B300 SXM6 AC has no listed ray tracing core count, while the mobile GPU explicitly includes 24 RT cores. The B300 SXM6 AC's 592 tensor cores match its TMU count, suggesting a design optimized for matrix operations rather than graphics rendering.

Memory architecture is fundamentally different. The B300 SXM6 AC uses 288 GB of HBM3e across an 8192-bit bus, delivering 8.19 TB/s of bandwidth. The RTX 2000 Mobile Ada Generation uses 8 GB of GDDR6 on a 128-bit bus, delivering 256.0 GB/s. That is a 32 times difference in memory bandwidth and a 36 times difference in capacity. The memory clock for both is listed at 2000 MHz, but the effective data rates differ: the B300 SXM6 AC runs at 8 Gbps effective, while the RTX 2000 Mobile Ada Generation runs at 16 Gbps effective. The wider bus on the server part completely dominates the higher per-pin rate of the mobile chip.

Power and packaging tell the story of intended use. The B300 SXM6 AC has a TDP of 1100 W, requires a 1500 W suggested PSU, and mounts as an SXM module with no display outputs. The RTX 2000 Mobile Ada Generation has a 50 W TDP, uses no power connectors, is an IGP with display outputs described as portable device dependent, and supports PCIe 4.0 x16 versus the B300 SXM6 AC's PCIe 6.0 x16. The B300 SXM6 AC exposes no DirectX, OpenGL, or Vulkan APIs, while the mobile GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The server part is not designed for graphics output at all.

The Verdict

The data shows a complete separation of purpose. The NVIDIA B300 SXM6 AC is a compute-dense server accelerator with 76.99 TFLOPS of FP32, 288 GB of HBM3e, and a 100th percentile ranking in the database. The NVIDIA RTX 2000 Mobile Ada Generation is a low-power mobile graphics processor with 12.99 TFLOPS of FP32, 8 GB of GDDR6, and no recorded benchmark score.

For anyone selecting hardware based on the recorded measurements, the B300 SXM6 AC wins every compute-oriented category: raw throughput, memory bandwidth, memory capacity, texture rate, and transistor count. The RTX 2000 Mobile Ada Generation wins only in pixel rate, ROP count, and API support, which are graphics-specific metrics irrelevant to a server module with no display outputs.

The 1100 W TDP of the B300 SXM6 AC versus 50 W for the mobile part is a decisive differentiator. The server GPU consumes 22 times the power budget, which aligns with its 5.9 times compute advantage. The efficiency ratio is not favorable to the larger chip, but the absolute performance is in a different class. The RTX 2000 Mobile Ada Generation is designed for environments where power and physical size are constrained, while the B300 SXM6 AC is designed for data centers with dedicated cooling and power infrastructure.

The release dates confirm the generational gap: the RTX 2000 Mobile Ada Generation launched in March 2023, while the B300 SXM6 AC arrived in September 2025. The predecessor and successor fields also differ, with the server part following Server Hopper and preceding Server Rubin, while the mobile part follows Ampere-MW and precedes Blackwell-MW.

Where Each One Wins

The B300 SXM6 AC wins decisively in compute-heavy scenarios. Its 76.99 TFLOPS FP32 and FP16 throughput, 1,202.9 GTexel/s texture rate, and 8.19 TB/s memory bandwidth make it suitable for large-scale matrix operations, high-bandwidth data processing, and memory-intensive inference tasks. The 288 GB HBM3e capacity allows loading substantially larger models than the 8 GB GDDR6 on the mobile part. The 100th percentile ranking confirms it sits at the top of the database's performance distribution.

The RTX 2000 Mobile Ada Generation wins in graphics-oriented metrics and power efficiency. Its 101.5 GPixel/s pixel rate exceeds the B300 SXM6 AC's 48.77 GPixel/s, and its 48 ROPs double the server part's 24. The 50 W TDP versus 1100 W makes it viable for portable devices where power delivery and thermal management are constrained. The inclusion of 24 ray tracing cores and full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support means it can render interactive graphics, which the B300 SXM6 AC cannot do at all.

The B300 SXM6 AC is the choice for server deployments requiring maximum compute density, based on its 100th percentile score and 7% lead over the closest rival. The RTX 2000 Mobile Ada Generation is the choice for mobile workstations needing graphics output and low power draw, based on its 50 W TDP and display support. The data does not support any crossover use case: the server part has no display outputs and no graphics APIs, while the mobile part has one-tenth the memory bandwidth and less than one-fifth the shading units. Each GPU wins in its designated domain, and the recorded specifications make that separation explicit.
