Intel Arc A380E x2 vs NVIDIA GB10 Comparison

Intel Arc A380E x2 and NVIDIA GB10 occupy different positions in the database. The Arc A380E x2 is an Intel product from the Alchemist generation, built on the Xe-HPG architecture, while the GB10 is an NVIDIA server-class part from the Blackwell 2.0 generation. The data shows a substantial performance gap between them, with the GB10 ranking in the 95th percentile of all GPUs and the Arc A380E x2 in the 50th percentile. This analysis relies entirely on recorded measurements and architectural specifications from the database.

Where Each One Wins

The NVIDIA GB10 dominates nearly every measurable category in the database. Its average benchmark score of 117,393 places it far ahead of the Arc A380E x2, which has an average benchmark score of 0 in the recorded data. The GB10 delivers 29.71 TFLOPS of FP32 compute, compared to 4.096 TFLOPS for the Arc A380E x2, a difference of roughly 7.3 times. In FP16, the GB10 maintains 29.71 TFLOPS at a 1:1 ratio, while the Arc A380E x2 reaches 8.192 TFLOPS at a 2:1 ratio, meaning the GB10 still leads by a wide margin even in reduced-precision workloads.

Memory capacity is another decisive win for the GB10. It carries 128 GB of LPDDR5X memory across a 256-bit bus, delivering 273.2 GB/s of bandwidth. The Arc A380E x2 uses 6 GB of GDDR6 on a 96-bit bus, providing 186.0 GB/s. The GB10's memory bandwidth is approximately 47% higher, and its capacity is more than 21 times larger. This suggests the GB10 is suited for large datasets and models that cannot fit within a 6 GB frame buffer.

The Arc A380E x2 does hold advantages in certain areas. It supports a full suite of graphics APIs, including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, whereas the database lists the GB10's DirectX, OpenGL, and Vulkan support as N/A. The Arc A380E x2 also provides eight mini-DisplayPort 2.0 outputs, compared to a single HDMI output on the GB10. For multi-display workstation setups, the Arc A380E x2 is the only option of the two that supports conventional graphics rendering APIs and high-density display connectivity.

Architecture Differences

The two products come from different foundries and process nodes. The Arc A380E x2 uses TSMC's 6 nm process with the DG2-128 chip, containing 7,200 million transistors on a 157 mm² die. The GB10 uses TSMC's 5 nm process with the GB20B chip, though its transistor count is listed as unknown in the database. The GB10's die size is 382 mm², which is about 2.4 times larger than the Arc A380E x2's die. Transistor density for the Arc A380E x2 is 45.9M per mm², while the GB10 has no density figure recorded.

Clock behavior differs significantly. The Arc A380E x2 runs at a flat 2000 MHz for both base and boost, with memory at 1937 MHz (15.5 Gbps effective). The GB10 has a base clock of 1665 MHz and a boost clock of 2418 MHz, with memory at 1067 MHz (8.5 Gbps effective). The GB10's boost clock is about 21% higher than its base, while the Arc A380E x2 shows no boost headroom in the recorded data.

Compute resources are heavily skewed toward the GB10. It has 6144 shading units, 384 texture mapping units, 48 ROPs, 48 ray tracing cores, and 384 tensor cores. The Arc A380E x2 has 1024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores, with no tensor core count recorded. The GB10 has 6 times the shading units, 6 times the TMUs, 1.5 times the ROPs, and 6 times the ray tracing cores.

Pixel and texture rates reflect these resource differences. The GB10 achieves 116.1 GPixel/s and 928.5 GTexel/s, while the Arc A380E x2 reaches 64.00 GPixel/s and 128.0 GTexel/s. The GB10 is about 81% faster in pixel throughput and 7.3 times faster in texture throughput.

Power and physical specifications also contrast. The Arc A380E x2 is a single-slot card rated at 130 W TDP with a 1x 6-pin power connector and a suggested PSU of 300 W. It measures 265 mm in length, 127 mm in height, and 20 mm in width. The GB10 is an integrated graphics processor (IGP) rated at 140 W TDP with no power connectors and a suggested PSU of 300 W. Its dimensions are 150 mm by 51 mm by 150 mm. The GB10 uses a PCIe 5.0 x16 interface, while the Arc A380E x2 uses PCIe 4.0 x8.

Production status differs as well. The Arc A380E x2 is marked end-of-life, with its predecessor listed as Xe Graphics and its successor as Battlemage. The GB10 is active, with its predecessor listed as Server Hopper and its successor as Server Rubin. The GB10's release date is October 2025, while the Arc A380E x2 was released in March 2024.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between the Arc A380E x2 and the GB10. The head-to-head array is empty, and the wins counters show 0 for both items. This means the comparison must rely on the GB10's standalone benchmark results and the architectural specifications of both products.

The GB10 has two recorded benchmark scores. In Geekbench OpenCL, it scores 120,137. In Geekbench Vulkan, it scores 114,648. Its average benchmark score is 117,393, placing it in the 95th percentile of all GPUs. The Arc A380E x2 has no recorded benchmark scores and an average benchmark score of 0, which places it in the 50th percentile. The percentile difference of 45 points indicates that the GB10 outperforms a large majority of the database's tracked GPUs, while the Arc A380E x2 sits at the median.

The nearest rivals to the GB10 provide context for its standing. The NVIDIA RTX 4000 SFF Ada Generation has an average score of 117,088, which is 0.3% lower than the GB10. The AMD Radeon PRO W7700 scores 118,976, which is 1.3% higher than the GB10. The NVIDIA Tesla V100 SXM2 16 GB scores 114,395, which is 2.6% lower. The NVIDIA RTX A5500 Mobile scores 113,944, which is 3.0% lower. These deltas show the GB10 sits in a tight competitive band, within roughly 1.3% of two workstation-class rivals and ahead of two others.

The Arc A380E x2 has no nearest rivals listed in the database, so no comparative deltas are available for it. Its 50th percentile ranking indicates it falls in the middle of the performance distribution, but the absence of benchmark scores means the database cannot quantify its position relative to specific competitors.

The Verdict

The recorded data points to a clear split in intended use. The NVIDIA GB10 is the strong choice for compute-heavy workloads that benefit from high FP32 throughput, large memory capacity, and wide memory bandwidth. Its 29.71 TFLOPS FP32, 128 GB of LPDDR5X, and 273.2 GB/s bandwidth make it suitable for large-scale data processing, server-side inference, and workloads that need substantial memory. Its 95th percentile ranking and average score of 117,393, alongside nearest rivals within 1.3% either way, place it in the upper tier of the database.

The Intel Arc A380E x2 is the only one of the two with conventional graphics API support. Its DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 compatibility, combined with eight mini-DisplayPort 2.0 outputs, make it a plausible option for display-centric or rendering-oriented tasks that require standard graphics interfaces. Its 50th percentile ranking and lack of recorded benchmark scores indicate it is not competitive with the GB10 in raw compute, but its feature set covers a different use case.

The data does not support a recommendation for the Arc A380E x2 in compute-heavy scenarios. The GB10 leads in every computational metric recorded: shading units, TMUs, ROPs, ray tracing cores, FP32, FP16, pixel rate, texture rate, memory size, and memory bandwidth. The Arc A380E x2 leads only in API compatibility and display output count. The GB10's 140 W TDP is only 10 W higher than the Arc A380E x2's 130 W, which makes the performance gap even more pronounced relative to power draw. The GB10 also uses no external power connectors, while the Arc A380E x2 requires a 1x 6-pin connector.

For users who need graphics API support and multi-display output, the Arc A380E x2 is the only viable option between the two. For users who need compute performance, memory capacity, and bandwidth, the GB10 is the clear choice based on all recorded metrics.
