NVIDIA GB10 vs NVIDIA H200 NVL Comparison

Head-to-Head Benchmarks

The recorded data shows a single head-to-head benchmark comparison between the NVIDIA H200 NVL and the NVIDIA GB10, and the result is decisive. In the Geekbench OpenCL test, the H200 NVL scores 334,891, while the GB10 scores 120,137. This gives the H200 NVL a win with a margin of 178.8% over the GB10. In practical terms, the H200 NVL delivers nearly three times the compute throughput of the GB10 in this specific workload, a gap that dwarfs the differences seen between most competing accelerators.

Context from the nearest rivals helps frame this margin. The H200 NVL sits in the 100th percentile among all GPUs in the database, with an average benchmark score of 334,891. Its closest competitor, the NVIDIA B200, scores 345,482, which puts the H200 NVL 3.1% behind that part. The H200 NVL is 5.3% ahead of the AMD Instinct MI300X, which scores 317,994, and 13.2% ahead of the NVIDIA L40S, which scores 295,763. The GB10, by comparison, sits in the 95th percentile with an average score of 117,393 across its OpenCL and Vulkan results. Its closest rival, the NVIDIA RTX 4000 SFF Ada Generation, scores 117,088, meaning the GB10 is just 0.3% ahead of that card. The GB10 is 1.3% behind the AMD Radeon PRO W7700, 2.6% ahead of the NVIDIA Tesla V100 SXM2 16 GB, and 3% ahead of the NVIDIA RTX A5500 Mobile.

The delta between the two parts is enormous: the H200 NVL outperforms the GB10 by a factor that is larger than the entire gap between the GB10 and the lowest-scoring rival in its own tier. The GB10’s average score of 117,393 is only 35% of the H200 NVL’s OpenCL result. No benchmark in the database shows the GB10 winning any test against the H200 NVL; the wins tally is 1 for the H200 NVL and 0 for the GB10. This is not a close contest. The data indicates a clear hierarchy where the H200 NVL occupies a performance tier that the GB10 cannot approach.

Architecture Differences

The architectural gap between these two NVIDIA parts is fundamental, not incremental. The H200 NVL is built on the Hopper architecture with the GH100 chip, while the GB10 uses the Blackwell 2.0 architecture with the GB20B chip. Both use a 5 nm process from TSMC, but the similarities end there. The H200 NVL’s die size is 814 mm², more than double the GB10’s 382 mm². The H200 NVL packs 80,000 million transistors, while the GB10’s transistor count is listed as unknown in the database. The transistor density of the H200 NVL is 98.3 million transistors per mm².

The compute resources differ sharply. The H200 NVL has 16,896 shading units, 528 TMUs, 24 ROPs, and 528 tensor cores. The GB10 has 6,144 shading units, 384 TMUs, 48 ROPs, 48 ray tracing cores, and 384 tensor cores. The H200 NVL’s shading unit count is 2.75 times that of the GB10. The H200 NVL also has 528 tensor cores versus 384 on the GB10, a 37.5% advantage in tensor hardware count. The GB10, however, includes 48 ray tracing cores, a feature the H200 NVL lacks entirely in the recorded specifications.

Clock behavior also diverges. The H200 NVL runs at a base clock of 1365 MHz and a boost clock of 1785 MHz. The GB10 runs at a base of 1665 MHz and boosts to 2418 MHz. Despite the GB10’s higher clocks, the H200 NVL’s raw throughput remains far superior due to its massive core count. The FP32 compute ratings confirm this: the H200 NVL delivers 60.32 TFLOPS, while the GB10 delivers 29.71 TFLOPS. The H200 NVL’s FP16 figure is 120.6 TFLOPS using a 2:1 ratio, whereas the GB10 achieves 29.71 TFLOPS at a 1:1 ratio. The H200 NVL’s FP16 output is more than four times that of the GB10.

Memory architecture is another point of divergence. The H200 NVL uses 141 GB of HBM3e on a 6144-bit bus, yielding 4.89 TB/s of bandwidth. The GB10 uses 128 GB of LPDDR5X on a 256-bit bus, yielding 273.2 GB/s. The H200 NVL’s memory bandwidth is 17.9 times that of the GB10, a staggering difference that heavily favors the H200 NVL in memory-bound workloads. The H200 NVL’s pixel rate is 42.84 GPixel/s, while the GB10’s is 116.1 GPixel/s, a case where the GB10 leads due to its higher ROP count and clock speed. Texture rates are nearly identical: 942.5 GTexel/s for the H200 NVL and 928.5 GTexel/s for the GB10.

Power and physical characteristics also differ. The H200 NVL has a TDP of 600 W, requires dual-slot cooling, uses an 8-pin EPS power connector, and needs a 1000 W suggested PSU. The GB10 is an integrated graphics processor with a 140 W TDP, no power connectors, and a 300 W suggested PSU. The H200 NVL is 267 mm long and 111 mm tall, while the GB10 is 150 mm by 51 mm by 150 mm. The H200 NVL has no display outputs; the GB10 includes one HDMI port.

The Verdict

The data points to a clear conclusion: the NVIDIA H200 NVL is the superior compute accelerator by a wide margin. Its 178.8% lead over the GB10 in the Geekbench OpenCL test is not an outlier; it is consistent with the architectural differences. The H200 NVL has 2.75 times the shading units, 37.5% more tensor cores, and 17.9 times the memory bandwidth of the GB10. Its FP32 throughput of 60.32 TFLOPS is more than double the GB10’s 29.71 TFLOPS, and its FP16 output of 120.6 TFLOPS is over four times the GB10’s 29.71 TFLOPS.

The GB10’s strengths are real but narrow. It operates at a higher boost clock, has more ROPs, includes ray tracing cores, and delivers a higher pixel rate. Its 140 W TDP makes it far more power-efficient than the H200 NVL’s 600 W envelope. The GB10 also has a launch MSRP of 3,999 USD, while the H200 NVL has no recorded launch price. But in raw compute performance, the GB10 cannot compete. Its average benchmark score of 117,393 places it in the 95th percentile, while the H200 NVL sits at the 100th percentile with a score of 334,891.

For workloads that demand maximum throughput, memory bandwidth, and tensor performance, the H200 NVL is the only choice. The GB10 is suited to environments where power draw, physical footprint, and integrated design matter more than peak compute. The database shows no scenario where the GB10 outperforms the H200 NVL in a recorded benchmark. The verdict is unambiguous: the H200 NVL dominates in performance, while the GB10 offers a lower-power alternative with specific feature advantages.

Where Each One Wins

The NVIDIA H200 NVL wins decisively in every compute benchmark recorded. Its Geekbench OpenCL score of 334,891 is 178.8% above the GB10’s 120,137. The H200 NVL’s FP32 throughput of 60.32 TFLOPS and FP16 throughput of 120.6 TFLOPS make it the clear choice for AI training, scientific simulation, and any workload that scales with raw floating-point performance. Its 4.89 TB/s memory bandwidth, enabled by HBM3e on a 6144-bit bus, gives it a massive advantage in data-intensive tasks such as large language model inference, high-performance computing, and memory-bound analytics. The H200 NVL’s 528 tensor cores further cement its position for matrix operations, and its 100th percentile ranking confirms it sits at the top of the database’s performance hierarchy.

The NVIDIA GB10 wins on efficiency and specific feature sets. Its 140 W TDP versus the H200 NVL’s 600 W means it draws far less power, making it suitable for compact or power-constrained deployments. Its integrated design, with no power connectors and a 300 W suggested PSU, simplifies installation relative to the H200 NVL’s dual-slot, 8-pin EPS requirement. The GB10’s 48 ROPs and 116.1 GPixel/s pixel rate exceed the H200 NVL’s 24 ROPs and 42.84 GPixel/s, giving it an edge in rasterization-heavy tasks, despite its lower overall compute. The inclusion of 48 ray tracing cores is a feature the H200 NVL does not offer, making the GB10 the better option for any workload involving ray-traced rendering. The GB10’s higher boost clock of 2418 MHz also provides an advantage in lightly threaded or latency-sensitive tasks that do not scale across thousands of cores.

In terms of successor lineage, the H200 NVL belongs to the Server Hopper generation with a predecessor of Server Ada and a successor of Server Blackwell. The GB10 belongs to the Server Blackwell generation with a predecessor of Server Hopper and a successor of Server Rubin. The GB10’s release date of 2025-10-14 is later than the H200 NVL’s 2024-11-17, indicating a newer product cycle, but the performance data shows that newer does not mean faster in this comparison. The GB10’s launch MSRP of 3,999 USD is recorded, while the H200 NVL has none listed, but the performance gap suggests the H200 NVL targets a different, higher-tier market segment.

For users prioritizing compute density, memory bandwidth, and tensor performance, the H200 NVL is the clear winner. For users prioritizing power efficiency, integrated form factor, ray tracing capability, or pixel throughput, the GB10 holds specific advantages. The benchmark record shows a single outcome: the H200 NVL wins the only head-to-head test, and no recorded test favors the GB10.
