Architecture Differences

The architectural divide between these two NVIDIA products is fundamental. The B200 SXM6 is built on the GB100 chip using the Blackwell architecture, designed for server-class compute workloads. The RTX 4060 Mobile uses the AD107 chip with the Ada Lovelace architecture, tailored for laptop graphics.

The transistor counts reveal the scale difference. The B200 SXM6 packs 208,000 million transistors on a 1628 mm² die, producing a transistor density of 127.8M per mm². The RTX 4060 Mobile contains 18,900 million transistors on a 159 mm² die, with a density of 118.9M per mm². The B200's die is over ten times larger physically and holds over eleven times more transistors.

Memory architecture differs completely. The B200 SXM6 uses HBM3e memory totaling 180 GB across an 8192-bit bus. The RTX 4060 Mobile uses GDDR6 memory totaling 8 GB across a 128-bit bus. This creates a bandwidth gap of 8.19 TB/s versus 256.0 GB/s, a factor of roughly 32 times in favor of the B200.

The B200 SXM6 has no display outputs and no consumer API support, indicating its role as a compute accelerator. The RTX 4060 Mobile has display outputs described as "Portable Device Dependent" and full API support including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The B200 also uses a PCIe 6.0 x16 interface, while the RTX 4060 Mobile uses PCIe 4.0 x8.

The B200 SXM6 includes 592 tensor cores and no listed RT cores. The RTX 4060 Mobile includes 96 tensor cores and 24 RT cores, making it suited for ray-traced graphics. The B200's shading unit count of 18,944 is roughly 6.2 times that of the RTX 4060 Mobile's 3,072.

Head-to-Head Benchmarks

Direct head-to-head benchmark data is not available in the recorded measurements, as the B200 SXM6 has no benchmark entries in the database. The RTX 4060 Mobile has a full set of recorded scores across multiple tests.

The RTX 4060 Mobile achieves an average benchmark score of 22,729 across its recorded tests. Its percentile ranking places it at 67 percent against all GPUs in the database. The B200 SXM6 sits at the 50th percentile with an average benchmark score of zero, indicating no recorded performance data.

Looking at the RTX 4060 Mobile's individual results, its Geekbench Vulkan score of 89,569 slightly exceeds its OpenCL score of 89,420. The PassMark G3D score of 17,469 dominates its other PassMark results, while the GPU compute score of 6,816 reflects compute-focused workloads. The DirectX 9 test shows 216 points, DirectX 11 shows 157 points, DirectX 10 shows 107 points, and DirectX 12 shows 73 points. The 2D graphics test records 730 points.

The nearest rivals for the RTX 4060 Mobile provide context. The NVIDIA GeForce RTX 2080 scores 22,895, which is 0.7 percent higher. The AMD Radeon RX 7700 XT scores 22,549, which is 0.8 percent lower. The Intel Arc B580 scores 23,021, which is 1.3 percent higher. The NVIDIA GeForce RTX 5060 Mobile scores 22,435, which is 1.3 percent lower. The RTX 4060 Mobile sits within a narrow band of roughly one to two percent of these competing products.

Without benchmark data for the B200 SXM6, a direct performance comparison cannot be quantified. The specification sheet indicates massive theoretical advantages for the B200 in raw compute, but the database contains no recorded test results to confirm real-world performance.

The Verdict

The recorded data shows two GPUs with fundamentally different purposes. The B200 SXM6 is a server accelerator with enormous memory capacity and compute throughput, designed for tasks where power consumption and physical size are secondary concerns. The RTX 4060 Mobile is a laptop GPU with modest power draw and full graphics API support.

For raw compute specifications, the B200 dominates. Its FP32 output of 69.34 TFLOPS is roughly six times the RTX 4060 Mobile's 11.61 TFLOPS. Its memory bandwidth of 8.19 TB/s is over thirty times the mobile part's 256.0 GB/s. Its 180 GB memory capacity dwarfs the 8 GB available to the RTX 4060 Mobile.

For graphics workloads, the RTX 4060 Mobile is the only viable option. The B200 has no display outputs, no DirectX support, no OpenGL support, and no Vulkan support. The RTX 4060 Mobile supports all three APIs and includes 24 RT cores for ray tracing.

The B200 requires a 1400 W suggested PSU and dissipates 1000 W, making it unsuitable for any conventional desktop or laptop. The RTX 4060 Mobile operates at 115 W with no external power connectors, fitting within mobile power budgets.

The RTX 4060 Mobile has recorded benchmark data showing it performs within one to two percent of the NVIDIA GeForce RTX 2080, AMD Radeon RX 7700 XT, Intel Arc B580, and NVIDIA GeForce RTX 5060 Mobile. The B200 has no recorded benchmarks, so its real-world performance relative to other server parts cannot be assessed from this database.

The choice depends on workload. Server compute requiring massive memory and bandwidth points to the B200. Mobile graphics with API support points to the RTX 4060 Mobile.

Where Each One Wins

The B200 SXM6 wins on every metric related to raw compute capacity. Its 69.34 TFLOPS FP32 performance exceeds the RTX 4060 Mobile by roughly a factor of six. Its 1,083.4 GTexel/s texture rate is nearly six times the mobile part's 181.4 GTexel/s. Its 180 GB HBM3e memory with 8.19 TB/s bandwidth provides capacity and throughput that the RTX 4060 Mobile cannot approach.

The B200 also wins on transistor count and die size, with 208,000 million transistors on 1628 mm² versus 18,900 million on 159 mm². Its tensor core count of 592 is over six times the RTX 4060 Mobile's 96, indicating a large advantage for AI and machine learning workloads.

The RTX 4060 Mobile wins on graphics-oriented specifications. Its pixel rate of 90.72 GPixel/s is more than double the B200's 43.92 GPixel/s. It has 48 ROPs versus 24, and it includes 24 RT cores where the B200 lists none. Its boost clock of 1890 MHz exceeds the B200's 1830 MHz, and its base clock of 1545 MHz is far above the B200's 120 MHz.

The RTX 4060 Mobile also wins on power efficiency and practical deployment. Its 115 W TDP is a fraction of the B200's 1000 W. It requires no external power connectors and fits an IGP form factor, while the B200 uses an SXM Module and needs a 1400 W suggested PSU.

The RTX 4060 Mobile wins on software compatibility. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, enabling gaming and general graphics applications. The B200 has no API support recorded.

The RTX 4060 Mobile wins on benchmark presence. It has nine recorded test scores across Geekbench and PassMark suites, achieving an average of 22,729 with a 67th percentile ranking. The B200 has no recorded benchmarks and sits at the 50th percentile with a zero average score.

For gaming, rendering on standard APIs, or any workload requiring display output, the RTX 4060 Mobile is the functional choice. For server-side compute, large-scale data processing, or AI training where memory capacity and bandwidth are critical, the B200 SXM6 offers specifications that the mobile part cannot match.
