Intel Arc A380E x2 vs Intel Arc Graphics 64EU Comparison

Head-to-Head Benchmarks

The benchmark database shows no direct head-to-head measurements between the Intel Arc A380E x2 and the Intel Arc Graphics 64EU. The A380E x2 has no recorded benchmark scores, while the Arc Graphics 64EU has a single entry: 733 points in 3DMark Steel Nomad DX12. This lack of overlapping data means the comparison must be built from architectural specifications and the 64EU's position relative to its own nearest rivals.

The Arc Graphics 64EU's 733-point score places it in the 3rd percentile of all GPUs, indicating it operates in the lower performance tier. Its nearest rivals in the database are the Intel Arc Graphics 32EU and 24EU, both scoring exactly 733 points, showing a 0% delta. The AMD Radeon HD 6470M trails at 723 points, a 1.4% deficit, while the NVIDIA GeForce GT 415M leads at 751 points, putting the 64EU 2.4% behind. The data indicates the 64EU is functionally tied with its smaller 32EU and 24EU siblings, which is a surprising result given the differences in execution resources.

For the A380E x2, the absence of benchmark scores means no direct numerical comparison is possible. However, the specification sheet offers clear compute advantages. The A380E x2 delivers 4.096 TFLOPS of FP32 throughput, more than double the 1.946 TFLOPS of the Arc Graphics 64EU. In FP16, the A380E x2 reaches 8.192 TFLOPS versus 3.891 TFLOPS for the 64EU, again a 2.1x gap. Pixel throughput favors the discrete card at 64.00 GPixel/s compared to 30.40 GPixel/s, and texture rate sits at 128.0 GTexel/s versus 60.80 GTexel/s. These figures indicate the A380E x2 should outperform the 64EU by a substantial margin in compute-bound workloads, though the lack of recorded benchmark data prevents a quantified statement.

Where Each One Wins

The Arc Graphics 64EU wins on integration and efficiency. It operates at a 65 W TDP, uses system shared memory, and requires no power connectors or dedicated cooling solution, as it is an integrated graphics processor. Its 3 nm process node, built by TSMC, represents a newer manufacturing technology than the 6 nm node used for the A380E x2. The 64EU also has a higher transistor density at 73.3M / mm² versus 45.9M / mm² for the discrete card. The base clock of 300 MHz is low, but the boost clock reaches 1900 MHz, which is only 100 MHz below the A380E x2's fixed 2000 MHz clock. The 64EU is an active product, while the A380E x2 is marked end-of-life.

The A380E x2 wins on raw performance potential and dedicated resources. It has 1024 shading units, double the 512 of the 64EU, along with 64 TMUs versus 32, and 32 ROPs versus 16. The discrete card includes 8 ray tracing cores, a feature entirely absent from the 64EU's specification. Memory bandwidth is a decisive advantage: the A380E x2 uses 6 GB of GDDR6 on a 96-bit bus, delivering 186.0 GB/s, whereas the 64EU relies on system shared memory with bandwidth described as system dependent. The A380E x2 also supports PCIe 4.0 x8, while the 64EU uses a ring bus interface. For gaming, rendering, or any workload that stresses memory throughput, the discrete card's dedicated VRAM and higher bandwidth should dominate.

The 64EU's shared memory architecture means its performance is heavily influenced by the host system's RAM speed and capacity, a variable that does not affect the A380E x2. The data shows the 64EU's 733-point score in Steel Nomad is modest, and the A380E x2's doubled compute and memory resources suggest it would score significantly higher, though no measurement exists to confirm this.

The Verdict

The database indicates two very different products. The Intel Arc A380E x2 is a discrete, single-slot card with a 130 W TDP, a 6-pin power connector, and a 300 W suggested PSU. It targets systems where a dedicated GPU is required and where its 8x mini-DisplayPort 2.0 outputs are useful for multi-display setups. Its end-of-life status and release date of March 2024 make it a legacy option, though its successor, Battlemage, is listed.

The Intel Arc Graphics 64EU is an integrated GPU within the Arrow Lake-S chip, sharing memory with the CPU. Its 65 W TDP is part of the overall processor power budget, and its display outputs are motherboard dependent. Released in October 2024, it is an active product with no listed successor. The 64EU's 3rd percentile ranking and its near-identical score to the 32EU and 24EU parts suggest that, at least in the Steel Nomad workload, execution unit count makes little difference, likely due to memory bandwidth limitations of shared system memory.

Users requiring a dedicated GPU with ray tracing, high bandwidth, and substantial compute throughput should choose the A380E x2 based on its specifications. Users building a compact or low-power system, or those who already own an Arrow Lake-S processor, would rely on the 64EU, accepting its lower performance ceiling. The data cannot declare a single winner because no shared benchmarks exist, but the specification sheet favors the discrete card for performance-oriented tasks.
