Architecture Differences

The B200 SXM6 and the RTX 4050 Mobile represent two distinct branches of NVIDIA's product stack. The B200 SXM6 belongs to the Server Blackwell generation, code-named GB100. The RTX 4050 Mobile belongs to the GeForce 40 Mobile generation, built around the AD107 chip. Both use a 5 nm process at TSMC, but the similarities end there.

The B200 SXM6 is a massive server accelerator. It contains 208,000 million transistors on a die measuring 1,628 mm². The RTX 4050 Mobile contains 18,900 million transistors on a die measuring 159 mm². The transistor density difference is modest at 127.8M per mm² versus 118.9M per mm², but the absolute scale difference is enormous, roughly 11 times more transistors on the server part.

The B200 SXM6 has 18,944 shading units, 592 texture mapping units, and 24 ROPs. It also carries 592 tensor cores. The RTX 4050 Mobile has 2,560 shading units, 80 TMUs, 48 ROPs, 20 ray tracing cores, and 80 tensor cores. The B200 SXM6 does not list ray tracing cores in the database.

Clock behavior differs sharply. The B200 SXM6 has a base clock of 120 MHz and a boost clock of 1,830 MHz. The RTX 4050 Mobile has a base clock of 1,455 MHz and a boost clock of 1,755 MHz. The server part idles at a very low clock but boosts higher, while the mobile part runs much closer to its maximum at all times.

Memory architecture is fundamentally different. The B200 SXM6 uses HBM3e with 180 GB capacity, an 8192-bit bus, and 8.19 TB/s bandwidth. The RTX 4050 Mobile uses GDDR6 with 6 GB capacity, a 96-bit bus, and 192.0 GB/s bandwidth. The server part has 30 times the memory capacity and over 42 times the bandwidth.

The B200 SXM6 has no display outputs and uses an SXM Module slot with a PCIe 6.0 x16 interface. The RTX 4050 Mobile is an integrated GPU package with portable device dependent display outputs and a PCIe 4.0 x8 interface. The server part requires a 1400 W suggested PSU and has a 1000 W TDP. The mobile part has a 50 W TDP and no power connectors.

The B200 SXM6 was released on 2024-10-31, while the RTX 4050 Mobile was released on 2023-01-02. The server part lists its predecessor as Server Hopper and successor as Server Rubin. The mobile part lists its predecessor as GeForce 30 Mobile and successor as GeForce 50 Mobile.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the B200 SXM6 and the RTX 4050 Mobile. The B200 SXM6 has no benchmark entries at all, while the RTX 4050 Mobile has nine recorded tests.

The RTX 4050 Mobile's benchmark results show a clear pattern. In Geekbench, it scores 74,748 in OpenCL and 75,235 in Vulkan. These are the two highest scores in its recorded set. In PassMark tests, the scores vary by workload: 79 in DirectX 10, 130 in DirectX 11, 61 in DirectX 12, 184 in DirectX 9, 633 in G2D, 14,423 in G3D, and 5,947 in GPU compute.

The G3D score of 14,423 dominates the mobile part's overall average. The G2D score of 633 is far lower, indicating that the GPU's 2D performance is not its strength. The DirectX 9 score of 184 exceeds the DirectX 11 score of 130, and both exceed the DirectX 10 score of 79. The DirectX 12 score of 61 is the lowest of the API-specific tests.

The RTX 4050 Mobile's average benchmark score of 19,049 places it at the 63rd percentile of all GPUs in the database. Its nearest rival, the AMD Radeon RX 6600, averages 19,036, a difference of only 0.1%. The NVIDIA Quadro K6000 also averages 19,030, again a 0.1% difference. The NVIDIA Tesla K20m averages 19,089, which is 0.2% higher than the RTX 4050 Mobile. The NVIDIA RTX 2000 Ada Generation averages 18,954, which is 0.5% lower.

The B200 SXM6 has a percentile ranking of 50 out of all GPUs, but this is based on no benchmark data. The percentile field appears to default to the midpoint when no scores exist. The RTX 4050 Mobile's 63rd percentile is a meaningful figure derived from actual measurements.

Since the B200 SXM6 has no benchmark scores, the head-to-head comparison cannot rely on direct measurements. The data instead shows that the RTX 4050 Mobile is a mid-range performer relative to the broader GPU landscape, while the B200 SXM6's performance characteristics must be inferred from its specifications alone.

The Verdict

The data shows two GPUs designed for entirely different purposes. The B200 SXM6 is a server accelerator with enormous compute resources, 180 GB of HBM3e memory, and a 1000 W TDP. The RTX 4050 Mobile is a laptop GPU with modest compute resources, 6 GB of GDDR6 memory, and a 50 W TDP.

On raw compute specifications, the B200 SXM6 dominates. Its FP32 performance of 69.34 TFLOPS is roughly 7.7 times the RTX 4050 Mobile's 8.986 TFLOPS. Its texture rate of 1,083.4 GTexel/s is roughly 7.7 times the mobile part's 140.4 GTexel/s. Its memory bandwidth of 8.19 TB/s is over 42 times the mobile part's 192.0 GB/s.

However, the RTX 4050 Mobile wins in several specific areas. Its pixel rate of 84.24 GPixel/s is nearly double the B200 SXM6's 43.92 GPixel/s. Its 48 ROPs are double the server part's 24. Its boost clock of 1,755 MHz is close to the server part's 1,830 MHz, but its base clock of 1,455 MHz is over 12 times higher. The mobile part also supports DirectX, OpenGL, and Vulkan, while the server part supports none.

The RTX 4050 Mobile has actual benchmark data, placing it at the 63rd percentile of all GPUs. The B200 SXM6 has no benchmark data, so its percentile of 50 is unverified. Anyone selecting between these two parts must rely on the recorded measurements for the mobile GPU and the specification sheet for the server GPU.

For a workload that requires graphics API support, display outputs, or low power consumption, the RTX 4050 Mobile is the only choice. For a workload that requires massive memory capacity, extreme bandwidth, or maximum compute throughput, the B200 SXM6 is the only option.

Where Each One Wins

The B200 SXM6 wins in compute-heavy server workloads. Its 69.34 TFLOPS of FP32 performance, 1,083.4 GTexel/s texture rate, and 8.19 TB/s memory bandwidth support large-scale parallel processing. The 180 GB of HBM3e memory accommodates models and datasets that would not fit in the RTX 4050 Mobile's 6 GB. The 592 tensor cores provide dedicated matrix math acceleration. The PCIe 6.0 x16 interface offers a modern, high-bandwidth host connection.

The RTX 4050 Mobile wins in graphics and mobile applications. Its 84.24 GPixel/s pixel rate exceeds the server part's 43.92 GPixel/s, meaning faster rasterization for display-oriented tasks. Its 48 ROPs double the server part's 24, improving fill-rate-bound workloads. Its 20 ray tracing cores enable hardware-accelerated ray tracing, which the B200 SXM6 does not list. Its support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 makes it usable for gaming and general graphics software, whereas the B200 SXM6 has no API support.

The RTX 4050 Mobile wins on benchmark evidence. Its average score of 19,049 is based on actual tests across Geekbench and PassMark. The B200 SXM6 has no recorded scores. The mobile part's 63rd percentile ranking reflects real-world measurement, while the server part's 50th percentile is a placeholder.

The B200 SXM6 wins on scale. Its 208,000 million transistors, 1,628 mm² die, and 18,944 shading units indicate a design built for maximum throughput. The RTX 4050 Mobile's 18,900 million transistors, 159 mm² die, and 2,560 shading units indicate a design built for efficiency within a 50 W power envelope.

The RTX 4050 Mobile wins on clock consistency. Its base clock of 1,455 MHz means it operates near full speed at all times. The B200 SXM6's base clock of 120 MHz suggests it relies heavily on boost behavior, which may vary with thermal and power conditions.

The B200 SXM6 wins on memory capacity and bandwidth. The 180 GB capacity and 8.19 TB/s bandwidth are in a different class from the 6 GB capacity and 192.0 GB/s bandwidth of the mobile part. For workloads that stream large datasets, this difference is decisive.

The RTX 4050 Mobile wins on power efficiency. Its 50 W TDP is 5% of the B200 SXM6's 1000 W TDP. The mobile part requires no power connectors and has no suggested PSU, while the server part requires a 1400 W suggested PSU. Systems with limited power budgets will favor the mobile part.

The B200 SXM6 wins on launch positioning. Its launch MSRP of 34,999 USD places it as a premium server product. The RTX 4050 Mobile has no launch MSRP, reflecting its role as an integrated mobile component rather than a standalone retail product.
