NVIDIA B300 SXM6 AC vs NVIDIA Jetson T4000 Comparison

The NVIDIA B300 SXM6 AC and the NVIDIA Jetson T4000 are both Blackwell-generation server products from NVIDIA, but they occupy opposite ends of the compute spectrum. The B300 SXM6 AC is a massive SXM module designed for maximum throughput in data center racks, while the Jetson T4000 is a compact IGP (integrated graphics processor) board aimed at embedded or edge deployments. Benchmark data shows a single Geekbench OpenCL score for the B300 SXM6 AC at 369,831, placing it in the 100th percentile of all GPUs. The Jetson T4000 has no recorded benchmark scores in the database, and its average benchmark score is listed as 0, placing it at the 50th percentile. This gap in recorded performance is the defining characteristic of the comparison.

The Verdict

The database indicates that the B300 SXM6 AC is the clear performance leader, with its single recorded benchmark score of 369,831 in Geekbench OpenCL. This result places it ahead of all nearby rivals: it is 7% ahead of the NVIDIA B200 (which scores 345,482), 10.4% ahead of the NVIDIA H200 NVL (334,891), 16.3% ahead of the AMD Instinct MI300X (317,994), and 25% ahead of the NVIDIA L40S (295,763). The B300 SXM6 AC also holds the 100th percentile position across all GPUs in the database, meaning no other recorded GPU achieves a higher average score. For workloads requiring maximum raw compute, such as large-scale AI training or high-performance computing, the B300 SXM6 AC is the only option with recorded data supporting its capability.

The Jetson T4000, by contrast, has no benchmark entries. Its average benchmark score is 0, and it sits at the 50th percentile, which is the median position. This does not necessarily indicate poor performance, but it means the database contains no measured evidence of how it performs in OpenCL or other tests. The Jetson T4000 uses a GB10B chip, which is a smaller die at 391 mm² compared to the B300 SXM6 AC's 1628 mm². It draws 90 W of power, whereas the B300 SXM6 AC has a TDP of 1100 W. The Jetson T4000 is an IGP with no display outputs, just like the B300 SXM6 AC, but its physical dimensions are recorded as 87 mm by 100 mm by 15 mm, making it a small form factor board. The B300 SXM6 AC has no recorded dimensions. The launch MSRP for the Jetson T4000 is 1,999 USD, which is stated once here as a reference point, but no pricing data exists for the B300 SXM6 AC.

The verdict from the data is straightforward: the B300 SXM6 AC delivers a recorded 369,831 OpenCL score, making it the top performer in the database, while the Jetson T4000 has no recorded scores, so its relative performance cannot be quantified. The B300 SXM6 AC suits environments where power and space are not constraints, given its 1100 W TDP and SXM Module slot width. The Jetson T4000, with a 90 W TDP and a suggested PSU of 250 W, targets deployments where low power draw and compact size are priorities, but the database offers no benchmark evidence to assess its compute capabilities. Users who need verified performance should choose the B300 SXM6 AC; users who need a low-power Blackwell device with no recorded benchmarks must accept the lack of measured data.

Architecture Differences

Both processors use the Blackwell architecture and are fabricated on a 5 nm process at TSMC. However, they diverge in chip design and feature set. The B300 SXM6 AC uses the GB110 chip, while the Jetson T4000 uses the GB10B chip. The B300 SXM6 AC has a die size of 1628 mm² and a transistor count of 208,000 million, resulting in a transistor density of 127.8M per mm². The Jetson T4000 has a die size of 391 mm², but its transistor count is recorded as unknown, and no transistor density is listed. This indicates that the B300 SXM6 AC is a much larger and more complex chip, with over 200 billion transistors, while the Jetson T4000's die is roughly a quarter of the size by area.

The B300 SXM6 AC is based on the Blackwell Ultra architecture, while the Jetson T4000 uses the standard Blackwell architecture. Both belong to the same generation, labeled as Server Blackwell (Bxx), and both have the same predecessor (Server Hopper) and successor (Server Rubin). The B300 SXM6 AC was released on 2025-09-10, and the Jetson T4000 was released later on 2026-01-04, so the B300 SXM6 AC is earlier in the product cycle.

Shading unit counts differ dramatically. The B300 SXM6 AC has 18,944 shading units, while the Jetson T4000 has 1,536. Texture mapping units (TMUs) are 592 on the B300 SXM6 AC versus 48 on the Jetson T4000. Render output units (ROPs) are 24 on the B300 SXM6 AC and 16 on the Jetson T4000. Tensor cores also differ: the B300 SXM6 AC has 592 tensor cores, while the Jetson T4000 has 64. The Jetson T4000 additionally includes 12 ray tracing cores, while the B300 SXM6 AC has no recorded RT core count. This suggests the Jetson T4000 has dedicated RT hardware, whereas the B300 SXM6 AC's RT capabilities are not listed in the database.

Memory architecture is another point of divergence. The B300 SXM6 AC uses HBM3e memory with 288 GB capacity, an 8192-bit bus width, and 8.19 TB/s bandwidth. The Jetson T4000 uses LPDDR5X memory with 64 GB capacity, a 256-bit bus width, and 273.2 GB/s bandwidth. The B300 SXM6 AC has a memory clock of 2000 MHz (8 Gbps effective), while the Jetson T4000 has a memory clock of 1067 MHz (8.5 Gbps effective). The B300 SXM6 AC's memory bandwidth is over 30 times higher, but the Jetson T4000's effective memory data rate is slightly faster per pin.

Clock speeds also differ. The B300 SXM6 AC has a base clock of 1665 MHz and a boost clock of 2032 MHz. The Jetson T4000 has a base and boost clock of 1530 MHz, with no boost differentiation. The B300 SXM6 AC's higher boost clock, combined with its massive shading unit count, drives its high compute throughput. The Jetson T4000's lower fixed clock suggests a power-constrained design.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two products. The headToHeadBenchmarks field is empty, and the wins counter for each item is 0. This means there is no direct comparative test where both GPUs ran the same workload and produced scores. The only benchmark data available is the B300 SXM6 AC's Geekbench OpenCL score of 369,831. The Jetson T4000 has no benchmark scores at all.

Without direct comparisons, the only way to assess relative performance is through the B300 SXM6 AC's nearest rivals. The B300 SXM6 AC scores 369,831, which is 7% higher than the NVIDIA B200's 345,482. It is 10.4% higher than the NVIDIA H200 NVL's 334,891. It is 16.3% higher than the AMD Instinct MI300X's 317,994. It is 25% higher than the NVIDIA L40S's 295,763. These deltas show that the B300 SXM6 AC outperforms every recorded rival in its proximity class, with the smallest margin over the B200 at 7% and the largest over the L40S at 25%.

The Jetson T4000 has no nearest rivals listed and no scores, so no comparative analysis is possible. The data simply shows that the B300 SXM6 AC is the highest-scoring GPU in the database, sitting at the 100th percentile. The Jetson T4000's 50th percentile is a median position, but with an average score of 0, this percentile likely reflects the lack of data rather than a measured middle-ground performance. In the absence of head-to-head results, the B300 SXM6 AC's recorded score stands as the sole quantitative performance indicator.

The FP32 and FP16 compute rates further illustrate the gap. The B300 SXM6 AC delivers 76.99 TFLOPS in FP32 and 76.99 TFLOPS in FP16 (1:1 ratio). The Jetson T4000 delivers 4.700 TFLOPS in FP32 and 4.700 TFLOPS in FP16 (also 1:1). The B300 SXM6 AC is approximately 16.4 times higher in raw floating-point throughput, based on these listed figures. Pixel rate for the B300 SXM6 AC is 48.77 GPixel/s, while the Jetson T4000 achieves 24.48 GPixel/s. Texture rate is 1,202.9 GTexel/s for the B300 SXM6 AC versus 73.44 GTexel/s for the Jetson T4000. These numbers, though not from a shared benchmark, indicate a vast difference in fill-rate and compute capabilities.
