NVIDIA B200 SXM6 vs NVIDIA RTX A1000 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark entries for the NVIDIA B200 SXM6 and NVIDIA RTX A1000. The B200 SXM6 has no benchmark scores on file, while the RTX A1000 has three recorded test results. This absence of overlapping measurements means a direct numerical comparison of application performance cannot be derived from the database.

The RTX A1000 delivers a 3DMark Steel Nomad DX12 score of 969. In Geekbench OpenCL, it records 52,078 points, and in Geekbench Vulkan, 49,574 points. These figures place the RTX A1000 at the 79th percentile among all GPUs in the database, with an average benchmark score of 34,207.

The B200 SXM6 sits at the 50th percentile among all GPUs, but with an average benchmark score of zero and no recorded tests, its percentile placement reflects the absence of data rather than measured performance. The nearest rivals for the RTX A1000 provide context: the NVIDIA RTX A2000 12 GB scores 34,154 (0.2% higher), the AMD Radeon RX 560 XT scores 34,133 (0.2% higher), the NVIDIA TITAN V scores 34,355 (0.4% higher), and the AMD Radeon RX 480 scores 33,997 (0.6% higher). The RTX A1000 trails the TITAN V by the largest margin among these rivals, yet the spread across all four is narrow, under 1% in either direction.

Where Each One Wins

For the RTX A1000, the recorded data shows wins in the three benchmark categories it participated in: 3DMark Steel Nomad DX12, Geekbench OpenCL, and Geekbench Vulkan. Its average score of 34,207 exceeds the B200 SXM6's recorded average of zero, indicating that in every measured test present in the database, the RTX A1000 outperforms the B200 SXM6 solely because the B200 SXM6 has no measurements.

The B200 SXM6, by contrast, wins on every architectural specification that determines theoretical compute capacity. It delivers 69.34 TFLOPS of FP32 performance versus 6.737 TFLOPS for the RTX A1000, a roughly tenfold advantage in raw floating-point throughput. Its texture rate reaches 1,083.4 GTexel/s compared to 105.3 GTexel/s. Memory bandwidth stands at 8.19 TB/s for the B200 SXM6 against 192.0 GB/s for the RTX A1000. The pixel rates are close, 43.92 GPixel/s for the B200 SXM6 and 46.78 GPixel/s for the RTX A1000, with the RTX A1000 actually holding a slight edge in that specific metric.

In use-case terms, the RTX A1000 is the only one of the two with measured application results, so for any workload represented by the three benchmark tests, the RTX A1000 is the proven option. The B200 SXM6 offers theoretical advantages in compute density, memory capacity, and bandwidth, which would apply to workloads that scale with those resources, but the database contains no benchmark confirmation of such scaling.

Architecture Differences

The B200 SXM6 uses the GB100 chip built on a 5 nm process at TSMC, while the RTX A1000 uses the GA107 chip on an 8 nm process at Samsung. The B200 SXM6 belongs to the Blackwell architecture and the Server Blackwell (Bxx) generation; the RTX A1000 belongs to the Ampere architecture and the Workstation Ampere (Ax000) generation.

The transistor counts differ enormously. The B200 SXM6 contains 208,000 million transistors on a die size of 1628 mm², yielding a transistor density of 127.8 million per mm². The RTX A1000 contains 8,700 million transistors on a 200 mm² die, for a density of 43.5 million per mm². The B200 SXM6 packs roughly 24 times the transistor count into about eight times the die area.

Compute resources show a similar scale gap. The B200 SXM6 has 18,944 shading units, 592 TMUs, and 24 ROPs. The RTX A1000 has 2,304 shading units, 72 TMUs, and 32 ROPs. The RTX A1000 includes 18 RT cores and 72 tensor cores; the B200 SXM6 lists 592 tensor cores with no RT core count recorded. The B200 SXM6 thus has over eight times the shading units, over eight times the TMUs, and over eight times the tensor cores, while the RTX A1000 has more ROPs and includes dedicated ray tracing hardware that the B200 SXM6 entry does not specify.

Memory architecture diverges completely. The B200 SXM6 uses 180 GB of HBM3e on an 8192-bit bus, delivering 8.19 TB/s of bandwidth. The RTX A1000 uses 8 GB of GDDR6 on a 128-bit bus, delivering 192.0 GB/s. The B200 SXM6 offers 22.5 times the memory capacity and roughly 43 times the bandwidth.

Clock behavior also differs. The B200 SXM6 has a base clock of 120 MHz and a boost clock of 1830 MHz, with memory at 2000 MHz (8 Gbps effective). The RTX A1000 has a base clock of 727 MHz and a boost of 1462 MHz, with memory at 1500 MHz (12 Gbps effective). The RTX A1000 starts at a much higher base clock but boosts to a lower peak than the B200 SXM6.

Power and physical specifications separate the two further. The B200 SXM6 draws 1000 W with a suggested PSU of 1400 W and mounts as an SXM Module with PCIe 6.0 x16. The RTX A1000 draws 50 W with a suggested PSU of 250 W, is a single-slot card measuring 163 mm by 69 mm, uses PCIe 4.0 x8, has no power connectors, and provides four mini-DisplayPort 1.4a outputs. The B200 SXM6 has no display outputs. API support also differs: the RTX A1000 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the B200 SXM6 lists N/A for all three.

The Verdict

The RTX A1000 is the only one of the two GPUs with measured performance data. Its three benchmark scores, an average of 34,207, and its 79th percentile placement among all GPUs confirm that it is a functional, tested product for the workloads represented by 3DMark Steel Nomad DX12, Geekbench OpenCL, and Geekbench Vulkan. Its nearest rivals sit within 0.6% of its average score, indicating that it performs in a tightly clustered band around the 34,000-point mark.

The B200 SXM6 presents a different profile entirely. It has no benchmark results, an average score of zero, and a 50th percentile ranking that reflects missing data rather than measured capability. Its specifications describe a device with far greater compute throughput, memory capacity, and bandwidth than the RTX A1000, but the database provides no evidence of how those specifications translate into application performance.

For any use case that relies on the recorded benchmark tests, the RTX A1000 is the only choice with supporting data. For use cases that depend on raw compute resources such as FP32 throughput, texture rate, or memory bandwidth, the B200 SXM6 offers the theoretical advantage, but the absence of measurements means that advantage remains unverified. The RTX A1000 also provides display outputs and API support, making it suitable for workstation tasks that require graphics output, while the B200 SXM6 is a compute module with no display capability. The B200 SXM6 carries a launch MSRP of 34,999 USD, while the RTX A1000 has no recorded launch MSRP.
