Intel Arc A380E x2 vs Intel Arc Graphics 48EU Mobile Comparison

Head-to-Head Benchmarks

The database contains no direct benchmark scores for either the Intel Arc A380E x2 or the Intel Arc Graphics 48EU Mobile. Both entries show an average benchmark score of zero, and the head-to-head comparison table is empty. Consequently, no measured performance deltas can be cited from recorded data. The absence of benchmark results means any performance assessment must rely entirely on architectural specifications and theoretical throughput figures.

The Arc A380E x2 delivers a peak FP32 throughput of 4.096 TFLOPS, while the Arc Graphics 48EU Mobile reaches 1,382.4 GFLOPS. The discrete part offers roughly three times the raw single-precision compute. In FP16 workloads, the A380E x2 achieves 8.192 TFLOPS using a 2:1 rate, compared to 2.765 TFLOPS for the mobile integrated solution. Pixel throughput also favors the discrete card: 64.00 GPixel/s versus 14.40 GPixel/s. Texture rate shows a similar gap, with 128.0 GTexel/s against 43.20 GTexel/s.

Memory bandwidth further separates the two. The A380E x2 uses 6 GB of GDDR6 on a 96-bit bus, delivering 186.0 GB/s. The mobile part relies on system shared memory, with bandwidth listed as system dependent. That distinction matters for any workload that saturates memory, as the discrete card has dedicated bandwidth while the integrated part shares the system bus.

The A380E x2 also includes 8 ray tracing cores, whereas the 48EU Mobile lists no RT core count. For applications that leverage hardware ray tracing, the discrete card has a structural advantage that the integrated part cannot match.

FAQ

Q: How do the shading unit counts compare?

A: The Intel Arc A380E x2 has 1,024 shading units, while the Intel Arc Graphics 48EU Mobile has 384. That is a 2.67x difference in raw shading hardware.

Q: What are the clock speed differences?

A: The A380E x2 runs at 2000 MHz base and 2000 MHz boost. The mobile part has a 300 MHz base clock and an 1800 MHz boost clock. The discrete card operates at a higher sustained frequency and does not rely on boost headroom to reach its top speed.

Q: Which GPU supports DirectX 12 Ultimate?

A: The A380E x2 supports DirectX 12 Ultimate (12_2). The 48EU Mobile is limited to DirectX 12 (12_1). The former also includes hardware ray tracing cores, which the latter lacks.

Q: What memory configurations do the two GPUs use?

A: The A380E x2 uses 6 GB of GDDR6 with a 96-bit bus and 186.0 GB/s bandwidth. The 48EU Mobile uses system shared memory, with bus width, type, and bandwidth all listed as system dependent.

Q: How much power does each part consume?

A: The A380E x2 has a TDP of 130 W and requires a 300 W suggested PSU. The 48EU Mobile has a TDP of 28 W and is an integrated graphics processor with no separate power connector.

Q: What is the production status of each GPU?

A: The A380E x2 is listed as end-of-life, with a release date of 2024-03-31. The 48EU Mobile is active, with a release date of 2023-12-13.

Architecture Differences

The two GPUs come from different architectural families. The A380E x2 uses the Xe-HPG architecture on the DG2-128 chip, part of the Alchemist generation (Arc 3). The 48EU Mobile uses Xe-LPG architecture on the Meteor Lake chip, part of the Arc Graphics-M generation. These are distinct designs with different goals: one is a discrete add-in card, the other an integrated processor.

The manufacturing processes diverge sharply. The A380E x2 is built 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 48EU Mobile uses a 10 nm process at Intel, with no transistor count or die size recorded in the database. The process node difference suggests the discrete card packs far more transistors into a dedicated die.

Compute resources differ substantially. The A380E x2 has 1,024 shading units, 64 TMUs, and 32 ROPs. The 48EU Mobile has 384 shading units, 24 TMUs, and 8 ROPs. The discrete card also has 8 ray tracing cores, while the integrated part has no RT core count listed. Both support Vulkan 1.4 and OpenGL 4.6, but the A380E x2 supports DirectX 12 Ultimate (12_2) versus DirectX 12 (12_1) for the mobile part.

Memory architecture is fundamentally different. The A380E x2 uses dedicated 6 GB GDDR6 on a 96-bit bus with 186.0 GB/s bandwidth. The 48EU Mobile uses system shared memory, with bandwidth dependent on the host system. The discrete card also has its own power delivery: a single 6-pin connector and a 130 W TDP, against 28 W for the integrated part.

The bus interface also differs. The A380E x2 connects via PCIe 4.0 x8, while the 48EU Mobile uses a Ring Bus. Display outputs are another separator: the A380E x2 provides 8x mini-DisplayPort 2.0 connectors, while the mobile part's outputs are dependent on the portable device.

The Verdict

The recorded data points to two very different products. The Intel Arc A380E x2 is a discrete, end-of-life graphics card built for sustained compute and rendering workloads. It has roughly three times the FP32 throughput, over four times the pixel rate, and nearly three times the texture rate compared to the 48EU Mobile. It carries dedicated 6 GB GDDR6 memory with 186.0 GB/s bandwidth, hardware ray tracing cores, and support for DirectX 12 Ultimate. Its 130 W TDP and single 6-pin power connector reflect a part designed for a powered slot in a desktop or embedded system.

The Intel Arc Graphics 48EU Mobile is an active, integrated GPU in the Meteor Lake platform. It draws 28 W, uses system shared memory, and delivers 1,382.4 GFLOPS of FP32 throughput. Its base clock of 300 MHz and boost of 1800 MHz indicate a power-constrained design that scales with thermal headroom. It supports DirectX 12 (12_1) but lacks the ray tracing cores and the higher-tier API feature set of the discrete card.

For workloads that demand maximum throughput, dedicated memory bandwidth, or hardware ray tracing, the A380E x2 is the clear choice based on specifications. For power-sensitive, portable systems where the GPU must share system resources, the 48EU Mobile is the only practical option, and its 28 W TDP reflects that design intent. The data does not support a direct performance comparison due to the absence of benchmark scores, but the architectural and specification gaps are unambiguous. The A380E x2 targets a different performance class entirely, and the 48EU Mobile targets efficiency and integration.
