Intel Arc A380E vs NVIDIA H800 SXM5 Comparison

Head-to-Head Benchmarks

The recorded data contains no head-to-head benchmark results for these two parts. The Intel Arc A380E and the NVIDIA H800 SXM5 occupy entirely different segments of the GPU market, and the database shows zero overlapping test scores. The Arc A380E is an entry-level, single-slot graphics card aimed at display output and light workloads, while the H800 SXM5 is a server accelerator module with no display outputs at all. Without shared benchmarks, direct performance comparisons rely on the raw specification sheet.

The Arc A380E posts 4.096 TFLOPS of FP32 compute, while the H800 SXM5 delivers 59.30 TFLOPS of FP32. That is a 14.5x gap in raw single-precision throughput. In FP16, the difference widens: the Arc offers 8.192 TFLOPS (2:1 ratio), while the H800 reaches 237.2 TFLOPS (4:1 ratio), a 29x difference. Pixel fill rates tell a different story: the Arc produces 64.00 GPixel/s versus the H800's 42.12 GPixel/s, meaning the smaller card actually leads in rasterization throughput per pixel. Texture rate favors the H800 decisively, 926.6 GTexel/s versus 128.0 GTexel/s, a 7.2x margin.

Memory bandwidth is where the two diverge most sharply. The H800 SXM5 uses 80 GB of HBM3 on a 5120-bit bus, producing 3.36 TB/s. The Arc A380E uses 6 GB of GDDR6 on a 96-bit bus, producing 186.0 GB/s. That is an 18x difference in bandwidth, which directly impacts any memory-bound workload. The H800 also carries 528 tensor cores, while the Arc has none listed, making the NVIDIA part the only one with dedicated AI acceleration hardware.

FAQ

Q: Can the Intel Arc A380E run modern graphics APIs?

A: Yes. The Arc A380E supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. It also includes 8 dedicated ray tracing cores, which the NVIDIA H800 SXM5 does not list.

Q: Does the NVIDIA H800 SXM5 support display output?

A: No. The H800 SXM5 has no display outputs listed. It is a compute-focused server module. The Arc A380E, by contrast, provides 4x DisplayPort 2.0 outputs.

Q: What is the memory capacity difference?

A: The H800 SXM5 has 80 GB of HBM3 memory on a 5120-bit interface with 3.36 TB/s bandwidth. The Arc A380E has 6 GB of GDDR6 on a 96-bit interface with 186.0 GB/s bandwidth.

Q: Which card has higher clock speeds?

A: The Arc A380E runs at a fixed 2000 MHz for both base and boost. The H800 SXM5 has a base clock of 1095 MHz and a boost clock of 1755 MHz. The Arc's higher clocks do not compensate for the H800's massive shader count advantage.

Q: What are the power requirements?

A: The Arc A380E has a 75 W TDP and requires no power connectors, with a suggested PSU of 250 W. The H800 SXM5 has a 700 W TDP, uses an 8-pin EPS connector, and requires a suggested PSU of 1100 W.

Q: Which card has more shading units?

A: The H800 SXM5 has 16,896 shading units versus 1,024 on the Arc A380E. The H800 also has 528 TMUs versus 64, though the Arc leads in ROPs with 32 versus 24.

The Verdict

The data indicates these are not competing products. The Intel Arc A380E is a low-power, display-oriented card with a 75 W TDP, single-slot design, and four DisplayPort 2.0 outputs. It is suited for systems that need basic graphics output plus modest compute, with its 4.096 TFLOPS FP32 and 8.192 TFLOPS FP16. The NVIDIA H800 SXM5 is a 700 W server accelerator with 59.30 TFLOPS FP32, 237.2 TFLOPS FP16, and 3.36 TB/s memory bandwidth, designed for data center workloads that require massive parallel throughput and large memory capacity.

The Arc A380E wins in pixel fill rate (64.00 vs 42.12 GPixel/s), has a higher boost clock (2000 vs 1755 MHz), and supports modern display standards. The H800 wins in every compute-heavy category: shader count (16,896 vs 1,024), texture rate (926.6 vs 128.0 GTexel/s), FP32 throughput, FP16 throughput, memory size, memory bandwidth, and tensor core support. The H800 also uses a newer 5 nm process versus the Arc's 6 nm, and integrates 80,000 million transistors versus 7,200 million.

Any user needing display output, ray tracing, or low power consumption should choose the Arc A380E. Any user running large-scale AI training, scientific simulation, or high-bandwidth data processing should choose the H800 SXM5. The two parts do not overlap in use cases.

Architecture Differences

The Intel Arc A380E uses the DG2-128 chip built on Xe-HPG architecture, part of the Alchemist (Arc 3) generation. It is fabricated on a 6 nm process at TSMC with 7,200 million transistors on a 157 mm² die, yielding a transistor density of 45.9M per mm². The chip includes 1024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. It has no tensor cores. The memory subsystem uses 6 GB of GDDR6 on a 96-bit bus with 15.5 Gbps effective speed, producing 186.0 GB/s. The card's predecessor is Xe Graphics, and its successor is Battlemage.

The NVIDIA H800 SXM5 uses the GH100 chip built on Hopper architecture, part of the Server Hopper (Hxx) generation. It is fabricated on a 5 nm process at TSMC with 80,000 million transistors on an 814 mm² die, yielding a transistor density of 98.3M per mm². The chip includes 16,896 shading units, 528 TMUs, 24 ROPs, and 528 tensor cores. It lists no ray tracing cores. The memory subsystem uses 80 GB of HBM3 on a 5120-bit bus with 5.3 Gbps effective speed, producing 3.36 TB/s. The card's predecessor is Server Ada, and its successor is Server Blackwell.

The architecture gap is fundamental. Intel's Xe-HPG is a consumer graphics architecture with fixed-function ray tracing and display output. NVIDIA's Hopper is a data center compute architecture with tensor cores for matrix operations and no display path. The H800's FP16 throughput of 237.2 TFLOPS is achieved via a 4:1 ratio relative to FP32, while the Arc's FP16 of 8.192 TFLOPS uses a 2:1 ratio. The H800 also supports PCIe 5.0 x16 versus the Arc's PCIe 4.0 x8, doubling the potential host interface bandwidth.

Where Each One Wins

The Intel Arc A380E wins in rasterization-oriented metrics. It produces 64.00 GPixel/s versus 42.12 GPixel/s on the H800, a 52% advantage in pixel fill rate. It also has a higher boost clock (2000 MHz vs 1755 MHz), which helps latency-sensitive workloads. The Arc includes 8 ray tracing cores, enabling hardware-accelerated ray tracing, a feature entirely absent from the H800's specification list. The Arc supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it functional for gaming and graphics applications. It has four DisplayPort 2.0 outputs, allowing multi-monitor setups. Its 75 W TDP and lack of power connectors mean it can run in systems with a 250 W suggested PSU, and its single-slot design fits in compact chassis.

The NVIDIA H800 SXM5 wins in every compute-heavy category. Its 59.30 TFLOPS FP32 is 14.5x the Arc's 4.096 TFLOPS. Its 237.2 TFLOPS FP16 is 29x the Arc's 8.192 TFLOPS. Texture rate is 926.6 GTexel/s versus 128.0 GTexel/s, a 7.2x advantage. Memory bandwidth is 3.36 TB/s versus 186.0 GB/s, an 18x advantage. The 80 GB HBM3 capacity is 13.3x the Arc's 6 GB, allowing far larger datasets to reside on-card. The 528 tensor cores provide dedicated hardware for AI inference and training, which the Arc lacks entirely. The 16,896 shading units deliver massive parallel throughput for scientific computing. The 5 nm process with 98.3M transistors per mm² indicates a denser, more advanced manufacturing node.

For a practical split: choose the Arc A380E for desktop workstations requiring display output, light gaming, or low-power embedded systems. Choose the H800 SXM5 for data center servers running AI models, high-performance computing, or any workload that needs large memory capacity and extreme bandwidth. The Arc is end-of-life with a release date of 2024-03-31; the H800 is active with a release date of 2023-03-20. The H800's active production status and server-class architecture align with long-term compute deployments, while the Arc's end-of-life status suggests it is a legacy part for existing designs.
