Intel Arc A380E x2 vs NVIDIA B300 Comparison

Head-to-Head Benchmarks

The recorded data for the Intel Arc A380E x2 and the NVIDIA B300 contains no direct benchmark scores, no average benchmark values, and no nearest rival comparisons. The database lists both products at the 50th percentile against all GPUs, with average benchmark scores of zero for each. The head-to-head benchmark table is empty, and neither product registers a single win in comparative testing. This absence of measured performance data means the comparison must rely entirely on architectural specifications and memory subsystem characteristics recorded in the database.

The most significant numerical disparity between the two products appears in raw compute throughput. The NVIDIA B300 delivers 76.99 TFLOPS of FP32 performance, while the Intel Arc A380E x2 provides 4.096 TFLOPS. The B300 therefore offers approximately 18.8 times the single-precision floating-point throughput of the A380E x2. In FP16, the gap widens dramatically: the B300 reaches 1,231.8 TFLOPS with a 16:1 ratio, whereas the A380E x2 achieves 8.192 TFLOPS with a 2:1 ratio. The B300's FP16 advantage exceeds 150-fold, reflecting its tensor-heavy server design.

Memory capacity and bandwidth reinforce the B300's dominance. The NVIDIA part carries 144 GB of HBM3e memory across a 4096-bit bus, delivering 4.10 TB/s of bandwidth. The Intel part uses 6 GB of GDDR6 on a 96-bit bus, producing 186.0 GB/s. The B300's memory bandwidth is roughly 22 times higher, and its capacity is 24 times larger. Texture throughput follows the same pattern: the B300 reaches 1,202.9 GTexel/s against the A380E x2's 128.0 GTexel/s, a 9.4-fold difference. Pixel rate is the one metric where the Intel card leads: 64.00 GPixel/s versus 48.77 GPixel/s for the B300, a 31% advantage driven by the Intel part's 32 ROPs compared to the B300's 24 ROPs.

Clock speeds present a mixed picture. The Intel Arc A380E x2 runs at a fixed 2000 MHz for both base and boost, with memory at 1937 MHz (15.5 Gbps effective). The NVIDIA B300 has a 1665 MHz base clock and a 2032 MHz boost clock, with memory at 2000 MHz (8 Gbps effective). The B300's boost clock exceeds the Intel part's fixed clock by only 32 MHz, but the memory clock comparison is inverted: the Intel memory runs at a higher effective data rate.

The Verdict

The database contains no benchmark scores for either product, so any verdict must derive from the recorded specifications. The NVIDIA B300 is a server-grade accelerator with 18944 shading units, 592 TMUs, 592 tensor cores, and 104,000 million transistors on a 5 nm TSMC process. The Intel Arc A380E x2 is an end-of-life client graphics card with 1024 shading units, 64 TMUs, 32 ROPs, 8 ray tracing cores, and 7,200 million transistors on a 6 nm TSMC process. The B300's transistor count is 14.4 times larger, and its shading unit count is 18.5 times higher.

The B300 targets server workloads with its 1400 W TDP, SXM module form factor, no display outputs, and PCIe 5.0 x16 interface. The A380E x2 targets embedded or multi-display client use with its 130 W TDP, single-slot design, 1x 6-pin power connector, 300 W suggested PSU, PCIe 4.0 x8 interface, and 8x mini-DisplayPort 2.0 outputs. These are fundamentally different product classes. The B300 is active in production as of its September 2025 release, while the A380E x2 is end-of-life after its March 2024 release.

The data supports a clear split: the B300 is the compute and memory powerhouse for server acceleration, while the A380E x2 is the display-capable, lower-power client card. There is no recorded scenario where the Intel part outperforms the NVIDIA part in compute or memory metrics. The only recorded metric where the Intel part leads is pixel rate, by 31%, which reflects its higher ROP count and pixel output capability.

Where Each One Wins

Compute-intensive server workloads: The NVIDIA B300 wins decisively. Its 76.99 TFLOPS FP32, 1,231.8 TFLOPS FP16, 592 tensor cores, and 1,202.9 GTexel/s texture rate position it for large-scale parallel computation. The 144 GB HBM3e memory with 4.10 TB/s bandwidth supports massive datasets. The 1400 W TDP and 1800 W suggested PSU indicate a system designed for sustained, high-throughput operation.

Display and embedded client applications: The Intel Arc A380E x2 wins on connectivity and pixel output. Its 8x mini-DisplayPort 2.0 outputs support multi-display configurations. The 64.00 GPixel/s pixel rate exceeds the B300's 48.77 GPixel/s. The 130 W TDP, single-slot width, and 1x 6-pin power connector allow integration into space-constrained systems. The 300 W suggested PSU requirement is far lower than the B300's 1800 W.

Memory bandwidth and capacity: The B300 dominates with 4.10 TB/s versus 186.0 GB/s, and 144 GB versus 6 GB. The Intel part's 186.0 GB/s bandwidth is sufficient for client graphics but insufficient for large-scale server workloads.

Architecture generation: The B300 uses Blackwell Ultra on a 5 nm process, released in September 2025, with a predecessor of Server Hopper and successor of Server Rubin. The A380E x2 uses Xe-HPG on a 6 nm process, released in March 2024, with a predecessor of Xe Graphics and successor of Battlemage. The B300 represents a newer, larger architecture generation.

Architecture Differences

The two GPUs come from entirely different architecture families and market segments. The Intel Arc A380E x2 uses the Xe-HPG architecture, specifically the DG2-128 chip, and belongs to the Alchemist generation (Arc 3). The NVIDIA B300 uses the Blackwell Ultra architecture, specifically the GB110 chip, and belongs to the Server Blackwell (Bxx) generation.

Process technology separates the two: Intel's chip is fabricated on a 6 nm process at TSMC, while NVIDIA's is on a 5 nm process at TSMC. The transistor counts reflect the scale difference: the Intel DG2-128 contains 7,200 million transistors on a 157 mm² die, yielding a transistor density of 45.9M per mm². The NVIDIA GB110 contains 104,000 million transistors with no recorded die size or density. The B300's transistor count is 14.4 times that of the A380E x2.

Memory architecture diverges sharply. The Intel part uses 6 GB of GDDR6 on a 96-bit bus with 186.0 GB/s bandwidth and 1937 MHz memory clock (15.5 Gbps effective). The NVIDIA part uses 144 GB of HBM3e on a 4096-bit bus with 4.10 TB/s bandwidth and 2000 MHz memory clock (8 Gbps effective). The B300's bus width is 42.7 times wider, and its memory type targets high-bandwidth server applications.

Compute resources differ across every category. The Intel chip has 1,024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores, with no tensor cores recorded. The NVIDIA chip has 18,944 shading units, 592 TMUs, 24 ROPs, and 592 tensor cores, with no ray tracing cores recorded. The B300's TMU count is 9.25 times higher, and its tensor core count matches its TMU count at 592.

Interface and form factor also separate the products. The Intel card uses PCIe 4.0 x8, is single-slot, measures 265 mm in length, 127 mm in height, and 20 mm in width, and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA module uses PCIe 5.0 x16, is an SXM module with no recorded dimensions, and has no recorded API support. The B300's bus interface is a full x16 link with the newer PCIe 5.0 standard.

Power delivery reflects the performance envelope. The Intel part draws a 130 W TDP with a 300 W suggested PSU. The NVIDIA part draws a 1400 W TDP with an 1800 W suggested PSU. The B300's TDP is 10.8 times higher than the A380E x2's.

Production status and release timing confirm the generational gap. The Intel Arc A380E x2 is end-of-life, released in March 2024, with a predecessor of Xe Graphics and successor of Battlemage. The NVIDIA B300 is active, released in September 2025, with a predecessor of Server Hopper and successor of Server Rubin. The B300 replaces the Hopper server line, while the A380E x2 follows the integrated Xe Graphics and precedes the Battlemage client architecture.
