Intel Arc A380E x2 vs NVIDIA GeForce RTX 4070 Mobile Comparison

Where Each One Wins

The benchmark data draws a sharp contrast between these two mobile and compact graphics solutions. The Intel Arc A380E x2, a dual-GPU configuration based on the DG2-128 chip, has no recorded benchmark scores in the database. Its average benchmark score is listed as zero, and it holds no wins in head-to-head comparisons. In contrast, the NVIDIA GeForce RTX 4070 Mobile has a substantial dataset, with nine separate benchmark entries covering OpenCL, Vulkan, DirectX 9 through 12, 2D, 3D, and compute workloads.

The RTX 4070 Mobile sits at the 73rd percentile among all GPUs in the database, while the Arc A380E x2 sits at the 50th percentile. That percentile gap reflects the absence of measured performance data for the Intel part, not an equivalence in capability. The NVIDIA part's average benchmark score is 27,435, a figure that places it in direct competition with desktop-class graphics cards. Its nearest rivals include the AMD Radeon RX 6700 XT with an average score of 27,425 (a delta of 0 percent), the NVIDIA GeForce RTX 3090 at 27,565 (0.5 percent higher), and the NVIDIA RTX PRO 4000 Blackwell at 27,135 (1.1 percent lower). The RTX 4070 Mobile effectively matches a previous-generation desktop flagship, which speaks to the performance density of the Ada Lovelace architecture.

For the Intel Arc A380E x2, the absence of scores means the database cannot confirm any workload where it wins. The wins tally shows zero for both parts in the head-to-head section, indicating no direct comparative benchmarks were recorded. The practical takeaway is that the RTX 4070 Mobile is the only one of the two with verifiable performance data, and that data shows a GPU operating in the upper tier of the database's rankings. The Arc A380E x2, by contrast, remains an unquantified entry, likely due to its niche positioning as a multi-display or embedded solution rather than a general-purpose gaming part.

Architecture Differences

The two GPUs come from different architectural generations with fundamentally different design priorities. The Intel Arc A380E x2 uses the Xe-HPG architecture on the DG2-128 chip, belonging to the Alchemist generation (Arc 3). It is built on a 6 nm process at TSMC, with 7,200 million transistors on a 157 mm² die. That yields a transistor density of 45.9 million per square millimeter. The NVIDIA GeForce RTX 4070 Mobile uses the Ada Lovelace architecture on the AD106 chip, part of the GeForce 40 Mobile generation. It is built on a 5 nm process, also at TSMC, with 22,900 million transistors on a 188 mm² die, giving a transistor density of 121.8 million per square millimeter. The density difference is stark: NVIDIA packs nearly three times as many transistors per unit area, which explains the large gap in compute resources.

The Intel part's Xe-HPG architecture is Alchemist's first discrete GPU generation, with a focus on scalable Xe cores. The RTX 4070 Mobile's Ada Lovelace architecture introduces third-generation ray tracing cores and fourth-generation tensor cores, both of which are reflected in the hardware counts. The RTX 4070 Mobile has 36 ray tracing cores and 144 tensor cores, while the Arc A380E x2 has 8 ray tracing cores and no tensor core field recorded. This is a fundamental architectural split: NVIDIA's design dedicates significant silicon to AI acceleration and ray tracing, while Intel's Alchemist generation provides more basic RT support without a dedicated tensor core array.

The foundry and process differences also affect power behavior. The RTX 4070 Mobile has a TDP of 115 W, while the Arc A380E x2 has a TDP of 130 W. Despite the higher power envelope, the Intel part delivers far lower raw compute: 4.096 TFLOPS FP32 versus 15.62 TFLOPS for the NVIDIA part. The FP16 comparison is similarly lopsided, with the Arc at 8.192 TFLOPS (2:1 ratio) and the RTX 4070 Mobile at 15.62 TFLOPS (1:1 ratio). The NVIDIA part's FP16 throughput matches its FP32 throughput, indicating a fully packed execution path, while Intel's 2:1 ratio means FP16 is processed at half rate.

Head-to-Head Benchmarks

The database records no head-to-head benchmark entries for these two GPUs. The headToHeadBenchmarks array is empty, and the wins tally shows zero for both sides. This means there is no direct measurement that pits the Intel Arc A380E x2 against the NVIDIA GeForce RTX 4070 Mobile in the same test suite. The comparative analysis must therefore rely on the RTX 4070 Mobile's standalone scores and the Intel part's lack of any recorded scores.

For the RTX 4070 Mobile, the strongest results come in the Geekbench tests. Its OpenCL score is 109,197, and its Vulkan score is 108,367. These are the highest individual scores in its dataset, indicating strong compute and graphics API performance. The Passmark suite shows a different pattern: the DirectX 9 score is 223, DirectX 11 is 179, DirectX 10 is 116, and DirectX 12 is 85. The Passmark G3D score is 19,587, while the G2D score is 763, and the GPU compute score is 8,399. The DirectX 12 score being lower than DirectX 9 is notable, but the G3D aggregate score reflects overall 3D rendering capability.

The RTX 4070 Mobile's nearest rival data provides context for these numbers. Its average score of 27,435 is nearly identical to the AMD Radeon RX 6700 XT's 27,425, a delta of 0 percent. The NVIDIA GeForce RTX 3090 scores 27,565, which is 0.5 percent higher, meaning the mobile 4070 comes within half a percent of a desktop 3090 in the database's aggregate metric. The RTX PRO 4000 Blackwell scores 27,135, which is 1.1 percent lower. These deltas are remarkably tight, suggesting that the RTX 4070 Mobile occupies a performance tier that is indistinguishable from several high-end desktop GPUs within measurement noise.

Specification Differences

The two GPUs differ across nearly every measurable specification. The Intel Arc A380E x2 uses the DG2-128 chip with 1,024 shading units, 64 texture mapping units, and 32 raster output units. The NVIDIA GeForce RTX 4070 Mobile uses the AD106 chip with 4,608 shading units, 144 TMUs, and 48 ROPs. The NVIDIA part has 4.5 times the shading units, 2.25 times the TMUs, and 1.5 times the ROPs. The memory subsystem also diverges: the Intel part has 6 GB of GDDR6 on a 96-bit bus, yielding 186.0 GB/s of bandwidth. The NVIDIA part has 8 GB of GDDR6 on a 128-bit bus, yielding 256.0 GB/s. The memory clock differs as well, with the Intel part at 1937 MHz (15.5 Gbps effective) and the NVIDIA part at 2000 MHz (16 Gbps effective).

Clock speeds show an interesting inversion. The Intel Arc A380E x2 runs at a base and boost of 2000 MHz, a flat clock profile. The NVIDIA RTX 4070 Mobile has a base clock of 1395 MHz and a boost of 1695 MHz. Despite the lower clocks, the NVIDIA part's much larger execution resource pool delivers vastly higher throughput. The pixel rate is 64.00 GPixel/s for the Intel part versus 81.36 GPixel/s for the NVIDIA part, and the texture rate is 128.0 GTexel/s versus 244.1 GTexel/s. The FP32 throughput gap is the widest: 4.096 TFLOPS versus 15.62 TFLOPS, a factor of roughly 3.8.

Physical and power characteristics differ as well. The Intel part is a single-slot card 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 NVIDIA part is an IGP (integrated graphics processor) with no power connectors and no suggested PSU, and its dimensions are not recorded. The Intel part has 8x mini-DisplayPort 2.0 outputs, while the NVIDIA part's display outputs are listed as "Portable Device Dependent," reflecting its mobile integration. Both use PCIe 4.0 x8 interfaces. The Intel part is end-of-life, released on 2024-03-31, with the predecessor Xe Graphics and successor Battlemage. The NVIDIA part is active, released on 2023-01-02, with the predecessor GeForce 30 Mobile and successor GeForce 50 Mobile.
