Intel Arc A380E vs NVIDIA RTX 4000 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results between the Intel Arc A380E and the NVIDIA RTX 4000 Mobile Ada Generation. Both entries in the database carry an empty benchmarks array, and the wins counter for each product is zero. Consequently, the comparison must rely entirely on the specification deltas and architectural characteristics recorded for each part.

The most decisive gap appears in raw compute throughput. The RTX 4000 Mobile Ada Generation delivers 24.72 TFLOPS of FP32 performance, while the Arc A380E delivers 4.096 TFLOPS. That places the NVIDIA part roughly six times ahead in single-precision floating-point work. The FP16 comparison is similarly lopsided: the RTX 4000 Mobile reaches 24.72 TFLOPS with a 1:1 ratio, whereas the Arc A380E reaches 8.192 TFLOPS but only with a 2:1 ratio, meaning its FP16 rate is achieved through packed execution rather than native throughput. The texture rate gap is also substantial, with the RTX 4000 Mobile at 386.3 GTexel/s versus 128.0 GTexel/s for the Arc A380E. Pixel rate follows the same trend, 133.2 GPixel/s versus 64.00 GPixel/s.

Memory bandwidth is another area where the NVIDIA part leads decisively. The RTX 4000 Mobile Ada Generation uses a 192-bit bus with 12 GB of GDDR6 memory, yielding 432.0 GB/s of bandwidth. The Arc A380E uses a 96-bit bus with 6 GB of GDDR6, yielding 186.0 GB/s. That is a 2.32x bandwidth advantage for the RTX 4000 Mobile, which directly impacts texture-heavy workloads and large dataset operations. The memory clock also differs, with the RTX 4000 Mobile running at 2250 MHz (18 Gbps effective) versus 1937 MHz (15.5 Gbps effective) for the Arc A380E.

The shader resource counts reinforce the compute advantage. The RTX 4000 Mobile packs 7424 shading units, 232 TMUs, 80 ROPs, 58 RT cores, and 232 tensor cores. The Arc A380E provides 1024 shading units, 64 TMUs, 32 ROPs, and 8 RT cores, with no tensor cores recorded. In ray tracing specifically, the RT core count difference is 58 versus 8, a 7.25x gap that suggests a very large difference in ray tracing workloads. The tensor core presence on the NVIDIA part, 232 of them, enables AI-accelerated features that the Intel part cannot match through dedicated hardware.

Clock behavior is one area where the Arc A380E shows a different design philosophy. Its base and boost clocks are both 2000 MHz, meaning it runs at a fixed frequency. The RTX 4000 Mobile has a base clock of 1290 MHz and a boost clock of 1665 MHz, a 375 MHz boost range. Despite the lower clocks, the RTX 4000 Mobile still achieves vastly higher throughput because of its much larger shader array and wider memory subsystem. The Arc A380E's higher clocks do not compensate for the 7.25x difference in shading units.

Both products support the same API feature set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. That means neither part is excluded from modern graphics APIs based on the recorded data. However, the underlying hardware capabilities differ substantially, and the API support alone does not indicate comparable performance.

Where Each One Wins

The RTX 4000 Mobile Ada Generation wins across every measurable compute and memory category in the database. Its FP32 throughput is 24.72 TFLOPS versus 4.096 TFLOPS, its texture rate is 386.3 GTexel/s versus 128.0 GTexel/s, its pixel rate is 133.2 GPixel/s versus 64.00 GPixel/s, and its memory bandwidth is 432.0 GB/s versus 186.0 GB/s. The NVIDIA part also has more than seven times the shading units, more than three times the TMUs, 2.5 times the ROPs, and over seven times the RT cores. It is the only one of the two with tensor cores, providing 232 of them. The 12 GB memory capacity is double the 6 GB on the Intel part, which matters for larger textures and datasets.

The Arc A380E does hold advantages in a few specific areas. Its base and boost clocks of 2000 MHz are higher than the RTX 4000 Mobile's 1290 MHz base and 1665 MHz boost. This fixed high clock could benefit workloads that are sensitive to clock speed rather than raw shader count, though the massive shader disadvantage makes this a narrow edge. The Arc A380E also has a lower TDP at 75 W versus 110 W for the RTX 4000 Mobile. That difference of 35 W can matter for systems with strict power budgets. Additionally, the Arc A380E is a single-slot card with four DisplayPort 2.0 outputs, while the RTX 4000 Mobile is an IGP with display outputs described as portable device dependent. For desktop or chassis configurations that need multiple fixed display connections, the Arc A380E offers a documented output configuration.

The transistor density also differs. The RTX 4000 Mobile's AD104 chip packs 35,800 million transistors into 294 mm², yielding 121.8M transistors per mm². The Arc A380E's DG2-128 chip has 7,200 million transistors on 157 mm², yielding 45.9M per mm². The 5 nm process used by the RTX 4000 Mobile versus the 6 nm process for the Arc A380E explains part of this density gap. The RTX 4000 Mobile also uses a PCIe 4.0 x16 interface, while the Arc A380E uses PCIe 4.0 x8, giving the NVIDIA part twice the host interface bandwidth.

Architecture Differences

The two GPUs come from different architecture families. The RTX 4000 Mobile uses Ada Lovelace architecture and belongs to the Ada-MW generation. The Arc A380E uses Xe-HPG architecture and belongs to the Alchemist (Arc 3) generation. The NVIDIA part's predecessor is Ampere-MW and its successor is Blackwell-MW. The Intel part's predecessor is Xe Graphics and its successor is Battlemage.

The process nodes differ by one generation: 5 nm for the RTX 4000 Mobile and 6 nm for the Arc A380E, both fabricated by TSMC. The transistor density difference, 121.8M per mm² versus 45.9M per mm², reflects both the process improvement and the larger chip design.

The RTX 4000 Mobile's Ada Lovelace architecture integrates tensor cores, 232 of them, which the Arc A380E lacks entirely. The RT core counts also differ dramatically: 58 versus 8. The shader organization differs as well, with the RTX 4000 Mobile using 7424 shading units and 232 TMUs, while the Arc A380E uses 1024 shading units and 64 TMUs.

Memory architecture differs in bus width, 192-bit versus 96-bit, and the resulting bandwidth, 432.0 GB/s versus 186.0 GB/s. Both use GDDR6 memory, but the RTX 4000 Mobile runs it at a higher effective speed of 18 Gbps versus 15.5 Gbps.

The FP16 execution approach differs. The RTX 4000 Mobile achieves 24.72 TFLOPS FP16 with a 1:1 ratio, meaning full-rate FP16. The Arc A380E achieves 8.192 TFLOPS FP16 with a 2:1 ratio, meaning FP16 is processed at half the rate of FP32 through packed instructions. This indicates a fundamental difference in how each architecture handles reduced-precision compute.

The power envelope differs by 35 W, with the RTX 4000 Mobile at 110 W and the Arc A380E at 75 W. The bus interface also differs, with the RTX 4000 Mobile using PCIe 4.0 x16 and the Arc A380E using PCIe 4.0 x8. The RTX 4000 Mobile is an integrated GPU package, while the Arc A380E is a single-slot discrete card with a fixed set of DisplayPort 2.0 outputs.

The Verdict

The recorded data points to a clear performance hierarchy. The NVIDIA RTX 4000 Mobile Ada Generation dominates the Intel Arc A380E in every computational and memory metric captured in the database. Its FP32 throughput of 24.72 TFLOPS is roughly six times the Arc A380E's 4.096 TFLOPS. Its memory bandwidth of 432.0 GB/s is more than double the 186.0 GB/s of the Arc A380E. Its 7424 shading units, 58 RT cores, and 232 tensor cores provide a hardware foundation that the Arc A380E cannot match with 1024 shading units, 8 RT cores, and no tensor cores.

The RTX 4000 Mobile is the appropriate choice for workloads that demand maximum compute throughput, ray tracing capability, AI acceleration through tensor cores, and larger memory capacity. Its 12 GB memory and 192-bit bus support larger datasets and higher resolution textures. The active production status and newer architecture generation, Ada Lovelace on 5 nm, indicate a current product with ongoing availability.

The Arc A380E holds relevance in specific constrained scenarios. Its 75 W TDP is lower than the RTX 4000 Mobile's 110 W, making it more suitable for power-limited systems. Its fixed 2000 MHz clock could benefit latency-sensitive tasks that prefer consistent clock behavior. The four DisplayPort 2.0 outputs give it a defined multi-display capability that the RTX 4000 Mobile does not specify, as the latter's outputs are portable device dependent. The single-slot form factor and lack of power connectors simplify physical installation.

However, the Arc A380E is end-of-life, while the RTX 4000 Mobile is active. The Intel part's launch date of 2024-03-31 is later than the RTX 4000 Mobile's 2023-03-20, but the production status indicates the Intel product has already reached the end of its lifecycle. The RTX 4000 Mobile also carries a successor, Blackwell-MW, while the Arc A380E's successor is Battlemage.

For users who need raw performance, the RTX 4000 Mobile Ada Generation is the only defensible choice based on the data. For users who need a low-power, single-slot GPU with fixed DisplayPort outputs and can accept a 6x FP32 deficit, the Arc A380E remains an option. There is no benchmark data to suggest the Arc A380E wins in any performance category. The specification comparison alone decides the verdict in favor of the NVIDIA part.
