Intel Arc A380 vs NVIDIA Tesla C2075 Comparison

Head-to-Head Benchmarks

The only directly comparable benchmark in the database is Geekbench OpenCL, and the result is a decisive victory for the Intel Arc A380. The NVIDIA Tesla C2075 scores 10,400 points, while the Intel Arc A380 scores 38,224 points. That puts the Intel card 72.8% ahead of the Tesla, a massive margin that reflects the generational gap between the two products. The data shows a single head-to-head test, and Intel wins it outright, leaving the Tesla with zero wins in the comparison.

Context from the nearest rival tables reinforces the story. The Tesla C2075 sits at the 48th percentile of all GPUs in the database, with an average benchmark score of 10,400. Its closest rivals include the AMD Radeon RX 6500M at 10,362 points (0.4% behind) and the NVIDIA GeForce GTX 950A at 10,273 points (1.2% behind). It also edges out the AMD Radeon RX 550X by 0.8% (10,481 points) and trails the AMD Radeon R9 M275X by 1.7% (10,582 points). These are all narrow margins, suggesting the Tesla C2075 is clustered tightly with older mobile and entry-level parts from roughly the same era.

The Intel Arc A380, by contrast, lands at the 44th percentile with an average benchmark score of 8,558 across all recorded tests. That average is dragged down by several low DirectX and compute scores, but its Geekbench OpenCL result is far above its own average. Its nearest rivals include the AMD FirePro W5170M at 8,595 points (0.4% ahead), the AMD Radeon HD 8870M at 8,462 points (1.1% behind), the NVIDIA GeForce MX330 at 8,458 points (1.2% behind), and the AMD Radeon 880M at 8,436 points (1.4% behind). The A380's average is within a couple of percentage points of these parts, but its OpenCL peak is in a different class entirely.

The Intel card also shows its strength across multiple APIs. In Geekbench Vulkan it scores 36,736 points. In Passmark G3D it hits 6,252 points, and in Passmark GPU Compute it manages 2,762 points. The Tesla has no comparable Vulkan or Passmark entries in the database, so the only direct comparison is OpenCL, where the Intel card dominates.

Architecture Differences

The two GPUs come from completely different eras and design philosophies. The NVIDIA Tesla C2075 uses the GF110 chip based on the Fermi 2.0 architecture, manufactured on a 40 nm process at TSMC. The Intel Arc A380 uses the DG2-128 chip based on Xe-HPG architecture, built on a 6 nm process, also at TSMC. That process difference alone explains a great deal of the performance gap: the Intel part packs 7,200 million transistors into a 157 mm² die, yielding a transistor density of 45.9 million per square millimeter. The Tesla, by contrast, holds 3,000 million transistors on a 520 mm² die, for a density of just 5.8 million per square millimeter. The Intel chip is physically smaller yet carries more than twice the transistor count.

Shader hardware tells a similar story. The Tesla C2075 has 448 shading units, 56 texture mapping units, and 48 render output units. The Arc A380 has 1,024 shading units, 64 TMUs, and 32 ROPs. The Intel card has more than double the shader count, slightly more TMUs, but fewer ROPs. The Arc A380 also includes 8 ray tracing cores, a feature entirely absent from the Fermi-based Tesla. Neither card has tensor cores listed in the database.

Clock speeds show the architectural leap. The Tesla memory runs at 783 MHz, or 3.1 Gbps effective. The Arc A380 has a base clock of 2000 MHz, a boost clock of 2050 MHz, and memory at 1937 MHz, or 15.5 Gbps effective. The Intel card's memory is not only faster but also uses a newer standard: GDDR6 versus the Tesla's GDDR5. Both cards have 6 GB of memory, but the bus widths differ substantially. The Tesla uses a 384-bit bus, delivering 150.3 GB/s of bandwidth. The Arc A380 uses a 96-bit bus, yet still achieves 186.0 GB/s thanks to the higher memory clock. The Intel card wins on bandwidth despite a quarter of the bus width.

Pixel and texture rates reflect the same trend. The Tesla produces 16.07 GPixel/s and 32.14 GTexel/s. The Arc A380 produces 65.60 GPixel/s and 131.2 GTexel/s. The Intel card is roughly four times faster in both metrics. Floating point performance is similarly lopsided: the Tesla delivers 1,027.7 GFLOPS in FP32, while the Arc A380 delivers 4.198 TFLOPS. The Intel card also supports FP16 at 8.397 TFLOPS with a 2:1 ratio; the Tesla has no FP16 figure listed.

API support differs as well. The Tesla lists DirectX 12 (11_0) and OpenGL 4.6, with no Vulkan entry. The Arc A380 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Intel card is also a dual-slot design with display outputs of 1x HDMI 2.1 and 3x DisplayPort 2.0, while the Tesla has just 1x DVI. Power requirements are covered in the specification section below.

Production status and release timing separate the two further apart. The Tesla was released in 2011-07-24 and is end-of-life, with the Tesla Kepler as its successor. The Arc A380 was released on 2022-06-13, also end-of-life, with Battlemage as its successor. The Tesla's predecessor is listed as Tesla, and the Intel card's predecessor is Xe Graphics.

The Verdict

The data points to one clear conclusion for raw performance: the Intel Arc A380 is the stronger GPU. Its Geekbench OpenCL score of 38,224 is 72.8% ahead of the Tesla C2075's 10,400. It also delivers roughly four times the pixel rate, four times the texture rate, and more than four times the FP32 throughput. It supports ray tracing, newer APIs, and a much smaller physical footprint with lower power draw. For anyone choosing based on benchmark results, the Arc A380 is the obvious pick.

However, the Tesla C2075 has its own niche. It holds a higher percentile ranking (48th versus 44th) and a higher average benchmark score (10,400 versus 8,558), because the Intel card's average is pulled down by weak Passmark DirectX and compute scores. The Tesla also uses a 384-bit memory bus, which historically suits certain compute workloads that favor wide buses over raw clock speed. Its nearest rivals are all within 1.7% of its score, indicating a stable, predictable performance level.

The decision depends on the workload. For modern gaming, API-heavy tasks, or any application that can use Vulkan or DirectX 12 Ultimate features, the Arc A380 is the only sensible choice. For legacy compatibility, older compute environments, or scenarios where the wider memory bus matters more than raw shader throughput, the Tesla C2075 remains functional, but the data shows it is far behind in almost every measurable way. The Intel card also carries a launch MSRP of 149 USD, which the database records, but the Tesla has no listed launch price.

Ultimately, the benchmark database shows a generational chasm. The Arc A380 outperforms the Tesla C2075 in the shared OpenCL test by a massive margin, offers modern features the Tesla cannot match, and does so at a fraction of the power draw. The Tesla's only advantages are its higher percentile ranking, its average score consistency, and its wider memory bus. For most users, the Intel card is the superior product.
