NVIDIA B200 vs NVIDIA RTX A5500 Mobile Comparison

The NVIDIA B200 and NVIDIA RTX A5500 Mobile occupy completely different corners of the GPU landscape, and their benchmark data reflects that divide. The B200 is a server-class accelerator built for massive compute workloads, while the RTX A5500 Mobile is an end-of-life laptop part from the Ampere generation. Their Geekbench OpenCL scores tell the story clearly: the B200 scores 345,482, while the RTX A5500 Mobile scores 124,287. That is a 178% lead for the B200. However, raw compute is not the only metric that matters, and the mobile part has its own strengths, particularly in portability and API support. The following analysis breaks down where each part wins, the architectural differences, and what the recorded data says about real-world usage.

Where Each One Wins

The B200 wins in every recorded benchmark comparison against the RTX A5500 Mobile. The only head-to-head test in the database is Geekbench OpenCL, where the B200 scores 345,482 against the A5500 Mobile's 124,287. That is a 178% delta, meaning the B200 delivers nearly three times the OpenCL performance. In the database's broader ranking, the B200 sits in the 100th percentile of all GPUs, while the RTX A5500 Mobile sits in the 94th percentile. So the B200 is at the very top of the performance pyramid, whereas the A5500 Mobile is still very capable but clearly a tier below.

However, the RTX A5500 Mobile has advantages that are not captured by compute scores. It is a portable device, with its display outputs listed as "Portable Device Dependent." This means it is designed for laptops and mobile workstations. The B200, by contrast, is an SXM module with no display outputs at all. The A5500 Mobile also supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the B200 lists no API support in the database. For tasks that require a display, graphics APIs, or mobility, the A5500 Mobile is the practical choice. For pure compute density, the B200 dominates.

The A5500 Mobile also has a much lower power envelope, with a TDP of 165 W compared to the B200's 1000 W. This makes the mobile part far easier to integrate into a workstation or laptop, while the B200 will require a server platform with substantial power delivery and cooling. The data does not include a suggested PSU for the A5500 Mobile, but the B200 lists a suggested PSU of 1400 W. That difference is critical for anyone planning a build.

Architecture Differences

The two GPUs are separated by two full generations of NVIDIA architecture. The B200 is built on the Blackwell architecture, using the GB100 chip, and is fabricated on a 5 nm process at TSMC. It packs 104,000 million transistors. The RTX A5500 Mobile uses the Ampere architecture with the GA103 chip, fabricated on an 8 nm process at Samsung, with 22,000 million transistors. The die size for the A5500 Mobile is 496 mm², while the B200's die size is not listed in the database.

The B200's memory subsystem is vastly different: it has 90 GB of HBM3e on a 4096-bit bus, delivering 4.10 TB/s of bandwidth. The A5500 Mobile has 16 GB of GDDR6 on a 256-bit bus, with 512.0 GB/s of bandwidth. The B200's memory bandwidth is 8x higher, which is a major factor in compute workloads.

The compute cores also differ. The B200 has 18,944 shading units, 592 TMUs, and 24 ROPs. The A5500 Mobile has 7,424 shading units, 232 TMUs, and 96 ROPs. The B50 has more shading and texture units, but the A5500 has more ROPs, which is why the A5500 Mobile's pixel rate is 144.0 GPixel/s, while the B200's is only 47.16 GPixel/s. The B200 compensates with a texture rate of 1,163.3 GTexel/s, versus the A5500's 348.0 GTexel/s.

Tensor cores are present on both. The B200 has 592 tensor cores, the A5500 has 232. The B200's FP16 performance is listed as 1,191.2 TFLOPS at a 16:1 ratio, while the A5500 FP16 is 22.27 TFLOPS at a 1:1 ratio. The B200's FP32 is 74.45 TFLOPS, versus the A5500's 22.27 TFLOPS. The A5500 has 58 RT cores, while the B200 data does not list any RT cores.

Head-to-Head Benchmarks

The database records a single head-to-head benchmark: Geekbench OpenCL. The B200 scores 345,482, and the A5500 scores 124,287. The B200 wins with a delta of 178%. This is the only direct comparison, but it is decisive. The B200 more than doubles the A5500's score, a gap that will make a difference in any compute-heavy workload.

Looking at the B200's nearest rivals in the database, the B200 is 3.2% ahead of the NVIDIA H200 NVL, 8.6% ahead of the AMD Instinct MI300X, and 16.8% ahead of the NVIDIA L40S. It trails the NVIDIA B300 SXM6 AC by 6.6%. This shows the B200 is at the top of the server-class heap, just behind the newest B300.

The A5500 Mobile's nearest rivals show a different picture. It is 0.4% behind the Tesla V100 SXM2 16 GB, 2.7% behind the RTX 4000 SFF Ada Generation, 2.9% ahead of the AMD Radeon PRO W7900, and 2.9% behind the NVIDIA GB10. The A5500 Mobile is in the middle of a tight pack, not a leader or a laggard. The 178% delta between the B200 and A5500 is far larger than any gap between the A5500 and its nearest competitors.

The Verdict

The data shows a clear performance hierarchy. The B200 is a server compute monster, ranking in the 100th percentile of all GPUs. It has a 178% lead over the A5500 Mobile in the only direct benchmark, and it sits 16.8% ahead of the NVIDIA L40S and 8.6% ahead of the AMD Instinct MI300X. For any workload that prioritizes raw OpenCL compute, memory bandwidth, or FP64-like density (though FP64 is not listed), the B200 is the obvious choice. It is a data center part designed for the most demanding tasks.

The RTX A5500 Mobile, by contrast, is a mobile workstation GPU from 2022. It is end-of-life, but it still holds a 94th percentile ranking. It has 96 ROPs and a much higher pixel rate at 144 GPixel/s, and it supports DirectX 12 Ultimate and Vulkan 1.4, which the B200 does not. It also draws only 165 W, making it deployable in a laptop. For a builder who needs graphics output, API support, or a portable workstation, the A5500 Mobile is the practical pick. The B200 cannot do any of these things, because it has no display outputs and no listed API support.

In short, pick the B200 if you are building a server rack and need maximum compute performance at any cost. Pick the RTX A5500 Mobile if you need a mobile graphics workstation with modern APIs and a reasonable power envelope. The two are not competing for the same buyer, and the benchmark data confirms that.
