Intel Arc B370 vs NVIDIA H800 PCIe 80 GB Comparison

Where Each One Wins

The recorded data paints a starkly asymmetric picture. The Intel Arc B370 has a single benchmark entry, a 3DMark Steel Nomad DX12 score of 1184, which places it at the 5th percentile of all GPUs in the database. That result lands it within 1.4% of a tight cluster of legacy AMD and ATI parts, with the ATI Mobility Radeon HD 5570 at 1186 (-0.2%), the ATI Radeon HD 5770 at 1190 (-0.5%), and the AMD Radeon HD 7650M at 1192 (-0.7%). The only rival it beats in that set is the AMD FirePro M2000 at 1168, where the Arc B370 holds a 1.4% advantage.

The NVIDIA H800 PCIe 80 GB has no benchmark scores recorded in the database. Its average benchmark score is listed as 0, with no nearest rivals and no head-to-head entries. Consequently, the wins tally is 0 for both products. The H800 cannot claim a measured victory in any test because no test data exists for it. What the database does provide is its percentile placement: the 50th percentile across all GPUs, which is a positional rank rather than a derived score. The Arc B370, by contrast, has a measured score but sits far lower in the overall distribution.

The practical conclusion from the data is that the Arc B370 is a low-power integrated graphics solution whose only recorded performance datapoint is comparable to a decade-old discrete mobile part. The H800 is a server accelerator with no recorded gaming or synthetic graphics benchmark, so its performance profile cannot be quantified from the database. The use-case split is therefore defined by what the numbers show: the Arc B370 is positioned at the entry level of the performance distribution, while the H800 occupies a mid-distribution rank with no measurable score to substantiate it.

Architecture Differences

The two products are architecturally unrelated. The Intel Arc B370 uses the Xe3-LPG architecture built on a 3 nm process at Intel, with the chip designated Panther Lake. It belongs to the Arc Graphics-M (Panther Lake) generation and is classified as an integrated graphics processor (IGP), meaning it has no bus interface beyond IGP and no power connectors. Its thermal design power is 25 W. The NVIDIA H800 PCIe 80 GB uses the Hopper architecture with the GH100 chip, fabricated on a 5 nm process at TSMC, and belongs to the Server Hopper (Hxx) generation. It is a dual-slot PCIe 5.0 x16 add-in card with a 350 W TDP and a single 16-pin power connector, requiring a 750 W suggested power supply.

The transistor counts are drastically different. The H800 integrates 80,000 million transistors on an 814 mm² die, yielding a transistor density of 98.3M per mm². The Arc B370's transistor count and die size are listed as unknown. The H800's memory subsystem is a discrete HBM2e configuration with 80 GB capacity, a 5120-bit bus, and 2.04 TB/s bandwidth. The Arc B370 uses system-shared memory with a system-dependent bandwidth, so its memory type, bus width, and capacity are all tied to the host platform rather than being fixed specifications.

Feature sets diverge as well. The Arc B370 exposes DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and includes 10 ray tracing cores. The H800 lists no DirectX, OpenGL, or Vulkan API support in the database, no ray tracing core count, but includes 456 tensor cores. The H800 has no display outputs, while the Arc B370's display outputs are portable-device dependent. These are not competing designs; they are different classes of silicon with different process nodes, foundries, memory strategies, and API targets.

Head-to-Head Benchmarks

No head-to-head benchmark entries exist in the database. The head-to-head array is empty, and the wins counters are both zero. The only meaningful comparison available is between the Arc B370's single score and the H800's absence of scores. The Arc B370's 1184 in 3DMark Steel Nomad DX12 is a real number, but with no H800 score to place against it, no direct performance delta can be calculated.

The nearest rivals for the Arc B370 provide the only comparative context. Its 1184 sits within 0.7% of the ATI Mobility Radeon HD 5570 (1186), the ATI Radeon HD 5770 (1190), and the AMD Radeon HD 7650M (1192), and it is 1.4% ahead of the AMD FirePro M2000 (1168). Those deltas are all within measurement noise, meaning the Arc B370's recorded performance is statistically indistinguishable from that cluster of older parts. The H800, with no score, cannot be positioned against any of them.

What the data does reveal is the sheer gap in raw specification between the two. The H800's FP32 throughput is 51.22 TFLOPS versus the Arc B370's 6.144 TFLOPS, an 8.3x difference. Its FP16 output is 204.9 TFLOPS (4:1) versus 12.29 TFLOPS (2:1) for the Arc B370. The H800's texture rate is 800.3 GTexel/s against 96.00 GTexel/s, and its pixel rate is 42.12 GPixel/s versus 48.00 GPixel/s, the one metric where the Arc B370 is higher. These are computed specifications, not benchmark results, but they establish the performance envelope that the missing benchmark data would presumably fill.

Specification Differences

The two products differ in nearly every measurable field. The Arc B370 uses a 3 nm Intel process; the H800 uses a 5 nm TSMC process. The Arc B370's chip is Panther Lake; the H800's is GH100. The Arc B370 is an IGP with a 25 W TDP, no power connectors, and no suggested PSU; the H800 is a dual-slot card with a 350 W TDP, a 1x 16-pin connector, and a 750 W suggested PSU. The Arc B370's bus interface is IGP; the H800's is PCIe 5.0 x16.

Clock behavior differs substantially. The Arc B370 has a 300 MHz base and a 2400 MHz boost; the H800 has a 1095 MHz base and a 1755 MHz boost. The H800's memory clock is 1593 MHz with 3.2 Gbps effective, while the Arc B370's memory clock is system shared. Memory width and bandwidth follow the same pattern: 5120-bit and 2.04 TB/s for the H800, system shared and system dependent for the Arc B370.

Compute unit counts are orders of magnitude apart. The Arc B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores. The H800 has 14592 shading units, 456 TMUs, and 24 ROPs, with 456 tensor cores and no listed RT core count. The Arc B370 has no tensor core field populated. The H800's die is 814 mm² with 80,000 million transistors; the Arc B370's die size and transistor count are unknown. The H800 has no display outputs; the Arc B370's outputs are portable-device dependent. The H800 measures 268 mm by 111 mm; the Arc B370 has no listed dimensions. Release dates are also distinct: the Arc B370 launched on 2026-01-26, the H800 on 2023-03-20. The H800 lists a predecessor (Server Ada) and successor (Server Blackwell); the Arc B370 lists neither.

The Verdict

The data supports a clear division of roles. The Intel Arc B370 is a low-power integrated part with a measured score of 1184 in 3DMark Steel Nomad DX12, placing it at the 5th percentile of all GPUs and within 1.4% of a group of legacy ATI and AMD parts. Its 25 W TDP, IGP bus interface, and system-shared memory mark it as a platform-integrated solution for portable devices. Its single benchmark result indicates entry-level graphics capability, nothing more.

The NVIDIA H800 PCIe 80 GB is a server accelerator with no benchmark scores in the database. Its 50th percentile rank is the only performance-related datapoint, and it carries no measured score to validate that position. Its specifications, however, are those of a high-end compute part: 51.22 TFLOPS FP32, 204.9 TFLOPS FP16, 456 tensor cores, 80 GB of HBM2e with 2.04 TB/s bandwidth, and a 350 W TDP. The absence of benchmark data means no direct performance claim can be made from the database, but the specification sheet alone separates it from the Arc B370 in compute capacity, memory bandwidth, and thermal envelope.

For a user selecting based on recorded measurements, the Arc B370 is the only product with a score, and that score is firmly in the low end of the distribution. For a user selecting based on raw specifications, the H800 is the only product with server-class compute resources, tensor cores, and a discrete memory subsystem. The two do not compete in the same usage scenario. The Arc B370 belongs in a portable device with no discrete power delivery; the H800 belongs in a server chassis with a 16-pin connector and a 750 W power supply. The database records no overlap in measured performance, and the specification differences confirm that none should be expected.
