Intel Arc A380E vs NVIDIA GeForce RTX 5070 Comparison

The Intel Arc A380E and the NVIDIA GeForce RTX 5070 occupy opposite ends of the GPU spectrum. The A380E is an end-of-life entry-level part from Intel’s Alchemist generation, designed for low-power, single-slot installations. The RTX 5070 is an active, high-performance Blackwell 2.0 part aimed at demanding workloads. The recorded data shows a clear separation in capabilities, with the RTX 5070 dominating compute and rasterization benchmarks, while the A380E presents a distinct set of specifications for specialized uses.

Where Each One Wins

The data reveals a one-sided competitive landscape. Benchmark results for the Intel Arc A380E are absent from the database, meaning its recorded percentile of 50 is based on its position among all tracked GPUs rather than direct test scores. In contrast, the NVIDIA GeForce RTX 5070 has a full suite of benchmark results, an average score of 40377, and a percentile ranking of 82. This percentile indicates the RTX 5070 outperforms 82% of all GPUs in the database.

The RTX 5070 wins every measurable category. It delivers substantially higher raw compute, memory bandwidth, and texture throughput. The A380E, with a 75 W TDP and no power connectors, targets environments where power draw and physical footprint are the primary constraints. Its single-slot design and 4x DisplayPort 2.0 outputs make it suitable for multi-display setups that do not require high frame rates. The RTX 5070, with its 250 W TDP and dual-slot design, provides the performance headroom for compute tasks and high-resolution rendering.

The use-case split is defined by power and performance. The A380E fits into low-profile or multi-GPU installations where each card must fit into a single slot and draw power solely from the PCIe slot. The RTX 5070 requires a dedicated 16-pin connector and a suggested 600 W power supply, indicating it is intended for full-size desktop systems with robust power delivery. The A380E also supports a wide range of display outputs with four DisplayPort 2.0 connections, while the RTX 5070 mixes one HDMI 2.1b and three DisplayPort 2.1b outputs.

Architecture Differences

The two GPUs come from different architectural generations. The Intel Arc A380E uses the Xe-HPG architecture on the DG2-128 chip, part of the Alchemist generation. It is fabricated on a 6 nm process at TSMC. The NVIDIA GeForce RTX 5070 uses the Blackwell 2.0 architecture on the GB205 chip, part of the GeForce 50 generation. It is fabricated on a 5 nm process, also at TSMC.

The transistor counts differ significantly. The A380E contains 7,200 million transistors on a die size of 157 mm², resulting in a transistor density of 45.9 million per square millimeter. The RTX 5070 contains 31,100 million transistors on a 263 mm² die, achieving a density of 118.3 million per square millimeter. The RTX 5070 packs more than four times the transistors into a die that is only about 67% larger.

Feature support also diverges. The A380E includes 8 ray tracing cores and no tensor cores. The RTX 5070 includes 48 ray tracing cores and 192 tensor cores. The tensor core count indicates a substantial advantage for AI-accelerated workloads on the NVIDIA part. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level compatibility is identical.

The memory architecture reflects the generational gap. The A380E uses GDDR6 memory with a 96-bit bus, while the RTX 5070 uses GDDR7 with a 192-bit bus. The process node difference, 6 nm versus 5 nm, contributes to the RTX 5070’s higher clock speeds and greater efficiency per transistor, although the power draw is considerably higher.

Head-to-Head Benchmarks

Direct head-to-head benchmark comparisons are not available in the database. The Intel Arc A380E has no recorded benchmark scores, while the NVIDIA GeForce RTX 5070 has ten separate test results. The absence of A380E scores means all comparative analysis relies on specification-derived performance indicators and the RTX 5070’s absolute scores.

The RTX 5070’s compute throughput is defined by its FP32 performance of 30.87 TFLOPS, compared to the A380E’s 4.096 TFLOPS. This is a 7.5x difference in single-precision floating-point operations. The FP16 figures show an even larger gap in one direction: the A380E delivers 8.192 TFLOPS with a 2:1 ratio, while the RTX 5070 delivers 30.87 TFLOPS with a 1:1 ratio. The RTX 5070 can maintain full FP32 throughput when operating on FP16 data, while the A380E halves its rate.

Memory bandwidth is another major differentiator. The A380E provides 186.0 GB/s, while the RTX 5070 provides 672.0 GB/s, a 3.6x advantage. This bandwidth differential directly impacts texture-heavy workloads and large data sets. The pixel rate of the RTX 5070 is 201.0 GPixel/s versus 64.00 GPixel/s for the A380E, and the texture rate is 482.3 GTexel/s versus 128.0 GTexel/s.

In the RTX 5070’s recorded benchmarks, the highest score comes from Geekbench Vulkan at 178923, followed by Geekbench OpenCL at 172660. The Passmark G3D score is 29137, and the Passmark GPU Compute score is 15787. The DirectX 10, 11, and 12 Passmark scores are 180, 277, and 108, respectively, with DirectX 9 scoring 320. The G2D score is 1305. These scores position the RTX 5070 near the AMD Radeon Pro 580, which has an average score of 40318 and a delta of 0.1%, and the AMD Radeon Pro WX 7100 at 40063 with a delta of 0.8%. It also sits slightly above the NVIDIA RTX A500 Mobile at 39568 with a delta of 2%. The closest rival with a higher average score is the AMD Radeon Pro 5300 at 40870, with a delta of -1.2%.

Specification Differences

The two cards differ across nearly every specification field. The RTX 5070 has 6144 shading units, 192 TMUs, and 80 ROPs. The A380E has 1024 shading units, 64 TMUs, and 32 ROPs. The RTX 5070’s shading unit count is six times higher, and its TMU count is three times higher.

Clock speeds favor the RTX 5070. Its base clock is 2325 MHz with a boost clock of 2512 MHz. The A380E’s base and boost clocks are both 2000 MHz. Memory clocks also differ: the RTX 5070 runs at 1750 MHz with 28 Gbps effective, while the A380E runs at 1937 MHz with 15.5 Gbps effective. Despite the lower memory clock, the RTX 5070’s wider bus and newer GDDR7 memory deliver far greater bandwidth.

Memory capacity and bus width are fundamental differentiators. The A380E has 6 GB of GDDR6 on a 96-bit bus. The RTX 5070 has 12 GB of GDDR7 on a 192-bit bus. The capacity difference of 6 GB directly impacts the size of data sets that can reside in VRAM. The RTX 5070 also has a higher transistor density, 118.3M per mm² versus 45.9M per mm², reflecting the more advanced 5 nm process.

Power and physical dimensions show a clear trade-off. The A380E has a TDP of 75 W, no power connectors, and a suggested PSU of 250 W. It measures 254 mm in length, 127 mm in height, and 20 mm in width. The RTX 5070 has a TDP of 250 W, one 16-pin power connector, and a suggested PSU of 600 W. It measures 245 mm in length, 115 mm in height, and 40 mm in width. The RTX 5070 is shorter and less tall but significantly thicker, requiring a dual-slot bracket.

The bus interface also differs. The A380E uses PCIe 4.0 x8, while the RTX 5070 uses PCIe 5.0 x16. This provides the RTX 5070 with more bandwidth to the host system. Display outputs are a point of similarity in count but not in type: the A380E offers four DisplayPort 2.0 ports, while the RTX 5070 offers one HDMI 2.1b and three DisplayPort 2.1b ports.
