Intel Arc B770 vs NVIDIA H100 SXM5 96 GB Comparison

Intel Arc B770 and NVIDIA H100 SXM5 96 GB occupy different corners of the hardware landscape. The Arc B770 is a dual-slot consumer graphics card built for real-time rendering and display output, while the H100 SXM5 is a 700 W server module with no display outputs, aimed at compute-heavy workloads. The recorded data shows a 50th percentile standing for both GPUs in the database, but their architectural priorities diverge sharply.

Where Each One Wins

The Intel Arc B770 wins in scenarios that demand rasterization throughput and display connectivity. It carries 128 ROPs and delivers a pixel rate of 307.2 GPixel/s, which is over six times the 47.52 GPixel/s of the H100. The Arc B770 also provides 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs, making it the only one of the two that can drive a monitor. Its 16 GB of GDDR6 memory on a 256 bit bus is sized for frame buffers, and its 512.0 GB/s bandwidth supports high-resolution textures and modern game assets. The card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so it slots into a standard graphics API stack.

The NVIDIA H100 SXM5 wins in compute throughput and memory capacity. Its FP32 performance is 66.91 TFLOPS, and its FP16 performance reaches 267.6 TFLOPS with a 4:1 ratio, far exceeding the Arc B770's 19.66 TFLOPS FP32 and 39.32 TFLOPS FP16 (2:1). The H100's 96 GB of HBM3 memory on a 5120 bit bus delivers 3.36 TB/s of bandwidth, which is roughly 6.5 times the Arc's bandwidth. The H100 also integrates 528 tensor cores, while the Arc B770 lists no tensor core count. The H100's SXM Module form factor and 8-pin EPS power connector indicate a server rack design, not a desktop graphics card.

Architecture Differences

The two GPUs use different silicon. The Arc B770 is built on the BMG-G31 chip with the Xe2-HPG architecture, part of the Battlemage (Arc 7) generation. The H100 SXM5 uses the GH100 chip with the Hopper architecture, classified under Server Hopper (Hxx). Both are fabricated on a 5 nm process at TSMC, but the die sizes differ substantially. The Arc B770 has a 368 mm² die, while the H100 SXM5 has an 814 mm² die. The H100 packs 80,000 million transistors, giving a transistor density of 98.3M per mm². The Arc B770's transistor count is listed as unknown.

The shading and texture resources also differ. The Arc B770 has 4096 shading units, 256 TMUs, and 128 ROPs, with 32 ray tracing cores. The H100 SXM5 has 16,896 shading units and 528 TMUs but only 24 ROPs, with no ray tracing core count recorded. The H100 instead dedicates area to 528 tensor cores. The texture rate reflects this split: the Arc B770 achieves 614.4 GTexel/s, while the H100 reaches 1,045.4 GTexel/s. Clock behavior differs too. The Arc B770 runs at a 2100 MHz base and 2400 MHz boost, while the H100 SXM5 runs at 1350 MHz base and 1980 MHz boost. The H100 compensates with a much wider memory bus and higher memory capacity.

The H100 SXM5 is listed as Active in production status, with a release date of March 2023 and a successor in Server Blackwell. The Arc B770 has a release date of December 2025 and lists its predecessor as Alchemist. The H100 succeeds Server Ada. Power delivery differs as well: the Arc B770 uses 1x 6-pin plus 1x 8-pin connectors with a 225 W TDP and a 550 W suggested PSU, while the H100 SXM5 uses an 8-pin EPS connector with a 700 W TDP and a 1100 W suggested PSU.

Head-to-Head Benchmarks

The recorded data does not include direct head-to-head benchmark scores for these two GPUs. Instead, the comparison relies on their individual measured specifications and compute rates.

The pixel rate is a clear win for the Arc B770. At 307.2 GPixel/s, it outperforms the H100 SXM5's 47.52 GPixel/s by a factor of roughly 6.5. This matters for fill-rate-bound rendering tasks, where the Arc's 128 ROPs can write pixels far faster than the H100's 24 ROPs.

The H100 SXM5 dominates in shading throughput. Its 66.91 TFLOPS FP32 is about 3.4 times the Arc B770's 19.66 TFLOPS. In FP16, the gap widens: the H100 delivers 267.6 TFLOPS versus the Arc's 39.32 TFLOPS, a ratio of about 6.8. The H100's 528 tensor cores give it a dedicated path for matrix operations, while the Arc B770 has no tensor core count listed.

Memory bandwidth is another decisive H100 advantage. The H100's 3.36 TB/s is roughly 6.5 times the Arc B770's 512.0 GB/s. The H100 also carries 96 GB of HBM3, six times the Arc's 16 GB of GDDR6. Texture rate favors the H100 as well, with 1,045.4 GTexel/s versus 614.4 GTexel/s.

The Arc B770 holds a clock advantage. Its 2400 MHz boost is higher than the H100's 1980 MHz boost, and its 2100 MHz base exceeds the H100's 1350 MHz base. Higher clocks help latency-sensitive workloads, but the H100's massive parallel resources overwhelm that advantage in raw throughput metrics.

Power efficiency, measured as performance per watt, is not directly listed, but the TDP figures show a wide gap. The Arc B770 draws 225 W, while the H100 SXM5 draws 700 W. The H100 delivers roughly 3.4 times the FP32 throughput at about 3.1 times the power draw, so the efficiency ratio is similar in FP32. In FP16, the H100's 4:1 ratio gives it a much larger throughput advantage per watt.

The Verdict

The data supports a clear split. The Intel Arc B770 is the choice for graphics rendering tasks that require high pixel fill rates, display connectivity, and standard graphics API support. Its 307.2 GPixel/s pixel rate, 128 ROPs, and DirectX 12 Ultimate support make it suited for real-time rendering workloads. Its lower 225 W TDP and dual-slot form factor fit a desktop chassis.

The NVIDIA H100 SXM5 is the choice for compute-heavy workloads that depend on massive parallel throughput, tensor operations, and large memory pools. Its 66.91 TFLOPS FP32, 267.6 TFLOPS FP16, 528 tensor cores, and 96 GB of HBM3 with 3.36 TB/s bandwidth position it for data center tasks. Its 700 W TDP and SXM Module form factor require server infrastructure.

Neither GPU is a general-purpose substitute for the other. The Arc B770 has no tensor core count listed and lacks the H100's compute scale. The H100 has no display outputs and only 24 ROPs, limiting its usefulness for rasterization. The production status of the H100 is Active, with a successor in Server Blackwell, while the Arc B770 lists no successor.
