NVIDIA B200 SXM6 vs NVIDIA RTX 2000 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The database records no shared benchmark scores for the NVIDIA B200 SXM6 and the NVIDIA RTX 2000 Mobile Ada Generation. Both entries show an average benchmark score of zero, with empty benchmark arrays and zero wins recorded for either side. Consequently, a direct numerical performance comparison cannot be established from the recorded data. What can be assessed are the raw specification deltas, which reveal the B200 SXM6 as a massively larger compute device, while the RTX 2000 Mobile operates at a fundamentally different scale.

The B200 SXM6 delivers 69.34 TFLOPS of FP32 throughput, a figure that is roughly 5.3 times higher than the RTX 2000 Mobile's 12.99 TFLOPS. Texture rate follows a similar pattern: the B200 SXM6 reaches 1,083.4 GTexel/s versus 203.0 GTexel/s for the RTX 2000 Mobile, a 5.3x advantage. Pixel rate is the one metric where the smaller GPU wins outright: the RTX 2000 Mobile produces 101.5 GPixel/s, while the B200 SXM6 manages 43.92 GPixel/s. This 2.3x advantage for the RTX 2000 Mobile stems from its higher ROP count (48 versus 24) and its substantially higher base and boost clocks.

Memory bandwidth is another categorical separation. The B200 SXM6 accesses 180 GB of HBM3e across an 8192-bit bus, yielding 8.19 TB/s of bandwidth. The RTX 2000 Mobile uses 8 GB of GDDR6 on a 128-bit bus, delivering 256.0 GB/s. That is a 32x gap in favor of the B200 SXM6. The B200 also holds a transistor count advantage at 208,000 million versus 18,900 million, though the RTX 2000 Mobile achieves a slightly higher transistor density per square millimeter at 118.9M / mm² compared to 127.8M / mm² for the B200 SXM6 (note: the B200 figure is actually higher, so the RTX 2000 Mobile does not lead here; the correct reading is that the B200 has 127.8M / mm², while the RTX 2000 Mobile has 118.9M / mm²).

Clock speeds invert the expected hierarchy. The RTX 2000 Mobile runs at a base of 1635 MHz and boosts to 2115 MHz. The B200 SXM6 idles at a 120 MHz base clock and boosts to 1830 MHz. The RTX 2000 Mobile's boost clock is 15.6% higher than the B200's boost. This explains the pixel rate win despite the B200 having far more shading units. The B200 carries 18,944 shading units, 592 TMUs, and 592 tensor cores; the RTX 2000 Mobile has 3,072 shading units, 96 TMUs, and 96 tensor cores. The B200 also has 24 ROPs, half the RTX 2000 Mobile's 48.

Where Each One Wins

The RTX 2000 Mobile Ada Generation wins decisively in rasterization throughput per clock. Its 101.5 GPixel/s fill rate exceeds the B200 SXM6's 43.92 GPixel/s, making it the stronger candidate for pixel-bound workloads such as traditional 2D rendering, shadow map generation, or any pipeline that stresses the ROP stage. The RTX 2000 Mobile also wins on clock speed, with a 2115 MHz boost versus 1830 MHz, and it supports a full API suite: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B200 SXM6 reports N/A for all three APIs, meaning it is not designed for general graphics API workloads.

The B200 SXM6 wins in every compute-heavy category. Its FP32 throughput of 69.34 TFLOPS is 5.3x higher. Its texture rate of 1,083.4 GTexel/s is 5.3x higher. Its memory bandwidth of 8.19 TB/s is 32x higher. Its memory capacity of 180 GB dwarfs the RTX 2000 Mobile's 8 GB, a 22.5x difference. The B200 also carries 592 tensor cores versus 96, positioning it for large-scale tensor operations, though both GPUs report FP16 at 1:1 ratio with FP32 (69.34 TFLOPS for the B200, 12.99 TFLOPS for the RTX 2000 Mobile).

The B200 SXM6 is a server accelerator with no display outputs, a PCIe 6.0 x16 interface, and a 1000 W TDP. The RTX 2000 Mobile is an integrated graphics processor (IGP) with a 50 W TDP, no power connectors, and display outputs described as "Portable Device Dependent." The B200 requires a 1400 W suggested PSU, while the RTX 2000 Mobile has no suggested PSU listed. For workloads that fit in 8 GB of memory and need graphics API support, the RTX 2000 Mobile is the functional choice. For workloads that need massive memory, extreme bandwidth, or server-class compute density, the B200 SXM6 is the only option between the two.

Architecture Differences

The B200 SXM6 uses the GB100 chip based on the Blackwell architecture, fabricated by TSMC on a 5 nm process. The RTX 2000 Mobile uses the AD107 chip based on Ada Lovelace, also fabricated by TSMC on a 5 nm process. Both share the same process node and foundry, but the die sizes diverge sharply. The B200 SXM6 measures 1628 mm² versus 159 mm² for the RTX 2000 Mobile, a 10.2x difference in physical area. Transistor counts follow: 208,000 million for the B200, 18,900 million for the RTX 2000 Mobile, an 11x difference. Transistor density also favors the B200 at 127.8M / mm² versus 118.9M / mm².

The B200 SXM6 belongs to the Server Blackwell (Bxx) generation, with its predecessor listed as Server Hopper and successor as Server Rubin. The RTX 2000 Mobile belongs to the Ada-MW generation, with predecessor Ampere-MW and successor Blackwell-MW. The B200 includes no ray tracing cores listed, while the RTX 2000 Mobile has 24 RT cores. The B200's 592 tensor cores are a server-scale implementation, while the RTX 2000 Mobile's 96 tensor cores are a mobile-scale implementation.

Memory architecture differs fundamentally. The B200 uses HBM3e with an 8192-bit bus and 8.19 TB/s bandwidth. The RTX 2000 Mobile uses GDDR6 with a 128-bit bus and 256.0 GB/s bandwidth. Both report a memory clock of 2000 MHz, but the effective data rates differ: 8 Gbps for the B200, 16 Gbps for the RTX 2000 Mobile. The B200 has no display outputs, no API support, and no power connectors listed. The RTX 2000 Mobile supports the full modern graphics API stack and operates as an IGP with portable device dependent outputs.
