Architecture Differences

The Intel Arc B770 and the NVIDIA H100 SXM5 94 GB represent fundamentally different design philosophies. The Arc B770 is built on the Xe2-HPG architecture, a gaming-oriented design from Intel's Battlemage (Arc 7) generation, using the BMG-G31 chip. The H100 SXM5 94 GB is built on the Hopper architecture, a server-focused design from NVIDIA's Server Hopper (Hxx) generation, using the GH100 chip. Both are fabricated on a 5 nm process at TSMC, but the die sizes diverge dramatically: the Arc B770 measures 368 mm², while the H100 SXM5 94 GB measures 814 mm². The H100's die is more than double the size, and its transistor count is listed at 80,000 million, with a density of 98.3M / mm². The Arc B770's transistor count is unknown, but its smaller die and lack of a density figure indicate a less dense layout.

The compute architectures differ substantially. The Arc B770 has 4096 shading units, 256 TMUs, and 128 ROPs, with 32 dedicated ray tracing cores and no tensor cores listed. The H100 SXM5 94 GB has 16896 shading units, 528 TMUs, and 24 ROPs, with 528 tensor cores and no ray tracing cores listed. The ROP count is striking: the Arc B770 has 128 ROPs versus only 24 on the H100, reflecting the Intel card's rasterization focus versus the NVIDIA card's compute-oriented design. The FP16 throughput tells the same story: the Arc B770 delivers 39.32 TFLOPS FP16 (2:1 ratio), while the H100 delivers 267.6 TFLOPS FP16 (4:1 ratio), indicating the H100's tensor core-driven FP16 acceleration.

Memory architecture is another major differentiator. The Arc B770 uses 16 GB of GDDR6 on a 256-bit bus, yielding 512.0 GB/s of bandwidth. The H100 SXM5 94 GB uses 94 GB of HBM3 on a 5120-bit bus, yielding 3.36 TB/s of bandwidth. The H100's memory bandwidth is over six times higher, and its capacity is nearly six times larger. The bus widths reflect the different memory technologies: 256-bit GDDR6 versus 5120-bit HBM3.

Clock speeds also diverge. The Arc B770 runs at a base clock of 2100 MHz and a boost clock of 2400 MHz, with memory at 2000 MHz (16 Gbps effective). The H100 SXM5 94 GB runs at a base clock of 1350 MHz and a boost clock of 1980 MHz, with memory at 1313 MHz (5.3 Gbps effective). Despite lower clock speeds, the H100's massive parallel width and memory bus deliver far higher peak throughput.

API support differs completely. The Arc B770 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The H100 SXM5 94 GB lists no DirectX, OpenGL, or Vulkan support, reinforcing its role as a compute-only server accelerator. The bus interface also differs: the Arc B770 uses PCIe 4.0 x16, while the H100 uses PCIe 5.0 x16.

Where Each One Wins

The Intel Arc B770 wins in rasterization-oriented tasks. Its 128 ROPs deliver a pixel rate of 307.2 GPixel/s, compared to the H100's 47.52 GPixel/s. That is a 6.5x advantage in pixel throughput, making the Arc B770 suited for traditional 3D rendering workloads where fill-rate matters. Its texture rate of 614.4 GTexel/s is lower than the H100's 1,045.4 GTexel/s, but the Arc B770's ROP advantage means it excels at final pixel output stages.

The Intel Arc B770 also wins in consumer-facing features. It has display outputs (1x HDMI 2.1a and 3x DisplayPort 2.1), while the H100 has no outputs at all. The Arc B770 supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it ready for gaming and graphics applications. The H100 lists no graphics API support, confirming it is not designed for interactive graphics.

The NVIDIA H100 SXM5 94 GB wins decisively in compute throughput. Its FP32 performance of 66.91 TFLOPS is 3.4x higher than the Arc B770's 19.66 TFLOPS. Its FP16 performance of 267.6 TFLOPS is 6.8x higher than the Arc B770's 39.32 TFLOPS. The H100's texture rate of 1,045.4 GTexel/s is 1.7x higher than the Arc B770's 614.4 GTexel/s, and its memory bandwidth of 3.36 TB/s is 6.6x higher. The H100's 94 GB memory capacity dwarfs the Arc B770's 16 GB, making it suitable for large models and datasets.

The H100 also wins in memory bandwidth and capacity, which is critical for data-center workloads like training, inference, and scientific computing. Its 5120-bit bus and HBM3 memory provide a 3.36 TB/s pipe, while the Arc B770's 256-bit bus and GDDR6 provide 512.0 GB/s.

Specification Differences

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark scores between the Intel Arc B770 and the NVIDIA H100 SXM5 94 GB. Both cards have an average benchmark score of 0 and a percentile ranking of 50 among all GPUs. The nearest rivals lists are empty for both cards, and the wins counters show 0 for each.

Instead, the comparison must rely on the specification-derived performance indicators. The most significant advantage for the NVIDIA H100 SXM5 94 GB is in memory bandwidth: 3.36 TB/s versus 512.0 GB/s, a 6.6x difference. This bandwidth advantage is paired with a 94 GB memory capacity versus 16 GB, allowing the H100 to hold far larger working sets.

In compute throughput, the H100 delivers 66.91 TFLOPS FP32 versus the Arc B770's 19.66 TFLOPS, a 3.4x advantage. In FP16, the H100 delivers 267.6 TFLOPS versus 39.32 TFLOPS, a 6.8x advantage. The H100's texture rate of 1,045.4 GTexel/s versus 614.4 GTexel/s is a 1.7x advantage. These figures indicate that the H100 is designed for high-throughput compute workloads where FP32 and FP16 performance dominate.

The Intel Arc B770 holds its own in rasterization metrics. Its pixel rate of 307.2 GPixel/s versus 47.52 GPixel/s is a 6.5x advantage for the Arc B770. This is driven by its 128 ROPs versus 24 ROPs. The Arc B770 also has a higher boost clock (2400 MHz versus 1980 MHz) and a higher base clock (2100 MHz versus 1350 MHz), though the H100's wider architecture compensates with more total throughput.

The power envelope differs by 475 W: the Arc B770 draws 225 W TDP, while the H100 draws 700 W TDP. The suggested PSU requirements reflect this: 550 W for the Arc B770 versus 1100 W for the H100. The H100's higher power draw is consistent with its larger die, more transistors, and higher memory bandwidth.

The Verdict

The data shows two cards built for entirely different roles. The Intel Arc B770 is a consumer graphics card with display outputs, graphics API support, and a rasterization-focused design. Its 128 ROPs and 307.2 GPixel/s pixel rate make it suitable for pixel-heavy rendering tasks. Its 225 W TDP and dual-slot form factor fit a standard desktop configuration, with 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs for display connectivity. The Arc B770 supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, covering all major graphics APIs.

The NVIDIA H100 SXM5 94 GB is a server accelerator with no display outputs, no graphics API support, and a compute-first design. Its 16896 shading units, 528 tensor cores, and 267.6 TFLOPS FP16 throughput position it for data-center workloads such as AI training and inference. Its 94 GB HBM3 memory and 3.36 TB/s bandwidth support large models and high-bandwidth data movement. Its 700 W TDP and SXM Module form factor require a server chassis with 8-pin EPS power and a 1100 W PSU.

The choice comes down to workload. For client-side graphics, gaming, or any application requiring display output and standard graphics APIs, the Intel Arc B770 is the only option with those capabilities. Its pixel rate advantage (307.2 GPixel/s versus 47.52 GPixel/s) and ROP count (128 versus 24) give it a clear edge in rasterization. For server-side compute, the NVIDIA H100 SXM5 94 GB dominates in raw throughput: 3.4x FP32, 6.8x FP16, 6.6x memory bandwidth, and nearly 6x memory capacity. The H100's 94 GB of HBM3 memory versus 16 GB of GDDR6 determines which workloads fit in on-card memory.

The production status confirms the H100 is an active product, released in 2023-03-20, with a known successor in Server Blackwell. The Arc B770 has a release date of 2025-12-31 and no successor listed, indicating a newer but less established position. The H100's transistor count of 80,000 million and die size of 814 mm² reflect a much larger investment in compute resources, while the Arc B770's 368 mm² die is smaller and less complex.

Neither card outperforms the other in absolute terms; each wins in its designated domain. The Arc B770 wins on pixel rate, ROP count, clock speed, and display connectivity. The H100 wins on shading units, tensor cores, FP32, FP16, texture rate, memory size, memory bandwidth, and bus width. The recorded data contains no direct benchmark scores to settle a head-to-head comparison, so the specification differences define the respective strengths.
