Intel Arc Pro B370 vs NVIDIA H100 CNX Comparison

The Verdict

The Intel Arc Pro B370 and NVIDIA H100 CNX occupy completely different positions in the hardware landscape. The Arc Pro B370 is an integrated graphics processor built for portability and efficiency, while the H100 CNX is a dual-slot server accelerator with no display outputs. The data shows no direct benchmark overlap, so the choice comes down to workload type: the Arc Pro B370 suits systems needing basic graphics in a compact integrated package, while the H100 CNX is designed for compute-heavy server workloads where massive memory bandwidth and tensor throughput matter. Users with portable devices requiring integrated graphics should select the Arc Pro B370. Users building server infrastructure with needs for high-bandwidth memory and parallel compute should select the H100 CNX.

Where Each One Wins

The Intel Arc Pro B370 wins in power efficiency and integration. Its 25 W TDP allows it to operate as an IGP with no power connectors and no separate slot requirement. The H100 CNX, by contrast, draws 350 W and requires a dual-slot footprint plus an 8-pin EPS connector. The Arc Pro B370 also delivers display output through the host portable device, whereas the H100 CNX has no display outputs at all.

The NVIDIA H100 CNX wins decisively in raw compute throughput. It delivers 53.84 TFLOPS FP32 performance versus 6.144 TFLOPS for the Arc Pro B370, a gap of roughly 8.8 times. In FP16, the H100 CNX reaches 215.4 TFLOPS (4:1) versus 12.29 TFLOPS (2:1) for the Arc Pro B370, a difference of about 17.5 times. Memory bandwidth tells a similar story: 2.04 TB/s versus system-dependent shared memory for the Arc Pro B370. The H100 CNX packs 80 GB of HBM2e on a 5120-bit bus, while the Arc Pro B370 relies on system shared memory.

The H100 CNX also holds advantages in texture rate (841.3 GTexel/s versus 96.00 GTexel/s) and shading units (14592 versus 1280). The Arc Pro B370 counters with a slightly higher pixel rate at 48.00 GPixel/s versus 44.28 GPixel/s, and it supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The H100 CNX lists no API support in the database.

The bus interfaces differ fundamentally. The Arc Pro B370 connects via IGP, making it part of the host processor package. The H100 CNX uses PCIe 5.0 x16. The Arc Pro B370 has no power connectors and fits as an IGP, while the H100 CNX requires a dual-slot design and an 8-pin EPS power connector. The H100 CNX also lists a suggested PSU of 750 W, which the Arc Pro B370 does not require.

Clocks reveal different design priorities. The Arc Pro B370 runs at a 300 MHz base and boosts to 2400 MHz. The H100 CNX runs at a 690 MHz base and boosts to 1845 MHz. The Arc Pro B370's higher boost clock suits its integrated role, while the H100 CNX's lower clocks reflect a design focused on sustained throughput across many cores.
