Intel Arc A380E x2 vs Intel Arc G3 Extreme Comparison

Head-to-Head Benchmarks

The recorded data shows no direct benchmark runs comparing the Intel Arc A380E x2 and the Intel Arc G3 Extreme. Both entries carry an average benchmark score of 0 and hold the 50th percentile position among all GPUs in the database. With zero head-to-head benchmark entries and zero wins recorded for either side, the quantitative comparison rests entirely on the specification sheets rather than measured performance deltas.

The most striking numerical contrast appears in raw compute throughput. The Arc G3 Extreme delivers 7.680 TFLOPS of FP32 performance, which is 87.5% higher than the Arc A380E x2's 4.096 TFLOPS. In FP16 workloads, the gap widens further: the G3 Extreme produces 15.36 TFLOPS versus 8.192 TFLOPS on the A380E x2, a 87.5% advantage as well. These figures represent the clearest mathematical wins for either product in the entire comparison.

Clock behavior separates the two sharply. The Arc A380E x2 runs at a fixed 2000 MHz for both base and boost clocks, with no dynamic range. The Arc G3 Extreme operates with a 300 MHz base clock and a 2500 MHz boost clock, an eightfold difference between idle and peak states. The G3 Extreme's boost clock sits 25% above the A380E x2's maximum, yet its base clock is 85% lower, reflecting fundamentally different power management strategies.

Memory architecture shows no common ground. The Arc A380E x2 uses 6 GB of dedicated GDDR6 memory on a 96-bit bus, delivering 186.0 GB/s of bandwidth at 1937 MHz (15.5 Gbps effective). The Arc G3 Extreme shares system memory entirely, with bus width and bandwidth marked as "System Shared" and "System Dependent" respectively. There is no fixed memory clock for the G3 Extreme, as memory speed depends entirely on the host platform's configuration.

Pixel and texture throughput present a rare case where the older card wins outright. The A380E x2 achieves 64.00 GPixel/s, beating the G3 Extreme's 60.00 GPixel/s by 6.7%. Texture rate follows the same pattern: the A380E x2 produces 128.0 GTexel/s versus 120.0 GTexel/s on the G3 Extreme, a 6.7% advantage. These wins come despite the G3 Extreme having 50% more shading units, indicating that the A380E x2's higher clock floor and dedicated memory bandwidth compensate for its smaller compute core count.

Where Each One Wins

The Arc A380E x2 wins in fixed-function throughput categories. Its pixel rate of 64.00 GPixel/s and texture rate of 128.0 GTexel/s both exceed the G3 Extreme's corresponding figures. The dedicated 186.0 GB/s memory bandwidth provides deterministic performance regardless of host system memory speed, a significant advantage for workloads sensitive to memory latency and bandwidth consistency. The A380E x2 also offers eight mini-DisplayPort 2.0 outputs, making it suited for multi-display configurations where output count matters more than raw compute.

The Arc G3 Extreme wins decisively in compute-oriented workloads. Its 1536 shading units outnumber the A380E x2's 1024 by 50%, and its 12 ray tracing cores exceed the A380E x2's 8 by 50% as well. The 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16 figures position it as the stronger choice for shader-heavy rendering, ray tracing, and FP16-accelerated workloads. The 2500 MHz boost clock provides headroom for burst compute tasks, while the 80 W TDP suggests it can sustain those boosts within a modest power envelope.

The G3 Extreme also wins in architectural recency. It uses the Xe3-LPG architecture on Intel's 3 nm process node, compared to the A380E x2's Xe-HPG architecture on TSMC's 6 nm node. The G3 Extreme belongs to the Arc Graphics-M (Panther Lake) generation, while the A380E x2 is part of the Alchemist (Arc 3) generation, which has reached end-of-life status. The G3 Extreme remains active in production, while the A380E x2 is discontinued.

The Verdict

The data indicates that the Arc G3 Extreme is the superior compute processor. It delivers 87.5% higher FP32 throughput and 87.5% higher FP16 throughput, carries 50% more shading units and 50% more ray tracing cores, and boosts to 2500 MHz. Its 3 nm process node and Xe3-LPG architecture represent a newer design generation. For any workload that scales with shading units, ray tracing cores, or raw TFLOPS, the G3 Extreme is the clear choice.

The Arc A380E x2 retains specific advantages that matter in certain deployments. Its 64.00 GPixel/s and 128.0 GTexel/s rates exceed the G3 Extreme's 60.00 GPixel/s and 120.0 GTexel/s, meaning rasterization-bound tasks may perform better on the older card. The dedicated 6 GB GDDR6 memory with 186.0 GB/s bandwidth provides predictable performance that does not depend on system memory configuration. The eight mini-DisplayPort 2.0 outputs make it a practical option for multi-display workstations.

The production status difference is decisive for system builders. The A380E x2 is end-of-life with a successor designated as Battlemage, while the G3 Extreme is active and was released two years later (2026 versus 2024). The G3 Extreme's system-shared memory model means total system RAM and memory speed determine its effective bandwidth, which could be either an advantage or a limitation depending on the host platform. The A380E x2's fixed 130 W TDP and 300 W suggested PSU provide clear power requirements, whereas the G3 Extreme's 80 W TDP and integrated design eliminate discrete power connector needs entirely.
