The Verdict

The recorded data suggests a clear performance hierarchy. The NVIDIA RTX A1000 holds the decisive edge in raw compute and memory resources. Its 2304 shading units, 6.737 TFLOPS of FP32 throughput, and 8 GB of GDDR6 memory with 192.0 GB/s bandwidth position it as the stronger card for general-purpose compute and graphics workloads. The database backs this up with an average benchmark score of 34207 and a 79th percentile ranking among all GPUs.

The Intel Arc A380E, by contrast, offers fewer shading units (1024), lower FP32 performance (4.096 TFLOPS), and less memory (6 GB on a 96-bit bus). Its 50th percentile ranking reflects a mid-pack position. The Arc A380E is end-of-life, while the RTX A1000 remains active, which matters for long-term availability and driver support.

For a user needing maximum compute throughput, the RTX A1000 is the clear pick from the data. For a user needing lower power draw, the RTX A1000 again wins with a 50 W TDP versus 75 W for the Arc A380E. The only areas where the Arc A380E shows an advantage are clock speed and display outputs: it runs at a flat 2000 MHz base and boost, and it provides four DisplayPort 2.0 connections versus four mini-DisplayPort 1.4a on the RTX A1000. The RTX A1000 is the superior choice across every measured benchmark metric.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between these two cards. However, the RTX A1000's own benchmark results provide a quantitative baseline. In 3DMark Steel Nomad DX12, the RTX A1000 scores 969. In Geekbench OpenCL, it scores 52078. In Geekbench Vulkan, it scores 49574. These scores contribute to an average benchmark score of 34207.

The Intel Arc A380E has no recorded benchmark scores in the database. Its percentile ranking of 50 places it in the middle of all GPUs, while the RTX A1000's 79th percentile ranking places it well above average. The gap in shading units is stark: 2304 versus 1024. The FP32 throughput difference of 6.737 TFLOPS versus 4.096 TFLOPS means the RTX A1000 processes 64% more single-precision floating-point operations per second. Texture rate follows the same pattern: the RTX A1000 achieves 105.3 GTexel/s versus 128.0 GTexel/s for the Arc A380E, a narrower but still meaningful difference. Pixel rate, however, favors the Intel card: 64.00 GPixel/s versus 46.78 GPixel/s, driven by the Arc A380E's higher clock speed.

The RTX A1000's nearest rivals in the database are all within 0.6% of its average score. The NVIDIA TITAN V is 0.4% faster, while the RTX A2000 12 GB, AMD Radeon RX 560 XT, and AMD Radeon RX 480 are 0.2%, 0.2%, and 0.6% slower respectively. This tight clustering indicates that the RTX A1000 performs at a level comparable to these established cards. The Arc A380E has no nearest rivals listed, which limits comparative analysis, but its 50th percentile standing places it far below the RTX A1000's 79th percentile.

Specification Differences

The two cards diverge on nearly every core specification. The Intel Arc A380E uses the DG2-128 chip with 7,200 million transistors on a 157 mm² die, while the NVIDIA RTX A1000 uses the GA107 chip with 8,700 million transistors on a 200 mm² die. Transistor density is slightly higher on the Intel card: 45.9M per mm² versus 43.5M per mm².

Clock speeds differ dramatically. The Arc A380E runs at a constant 2000 MHz for both base and boost. The RTX A1000 has a base clock of 727 MHz and a boost clock of 1462 MHz. Memory clocks also differ: the Arc A380E runs at 1937 MHz with 15.5 Gbps effective speed, while the RTX A1000 runs at 1500 MHz with 12 Gbps effective speed.

Memory configuration favors the RTX A1000: 8 GB versus 6 GB, and a 128-bit bus versus a 96-bit bus. Bandwidth is 192.0 GB/s versus 186.0 GB/s. The compute unit counts show a large gap: 2304 shading units, 72 TMUs, and 32 ROPs for the RTX A1000, against 1024 shading units, 64 TMUs, and 32 ROPs for the Arc A380E. The RTX A1000 also has 18 RT cores and 72 tensor cores, while the Arc A380E has 8 RT cores and no tensor cores listed.

Power and physical dimensions differ. The Arc A380E has a 75 W TDP, while the RTX A1000 has a 50 W TDP. Both suggest a 250 W power supply. The Arc A380E measures 254 mm in length, 127 mm in height, and 20 mm in width. The RTX A1000 measures 163 mm in length and 69 mm in height, with no width recorded. Both are single-slot cards with no power connectors.

Display outputs differ: the Arc A380E provides 4x DisplayPort 2.0, while the RTX A1000 provides 4x mini-DisplayPort 1.4a. Both use PCIe 4.0 x8. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Architecture Differences

The Intel Arc A380E is built on the Xe-HPG architecture, part of the Alchemist generation (Arc 3). The NVIDIA RTX A1000 is built on the Ampere architecture, part of the Workstation Ampere (Ax000) generation. The process nodes differ: 6 nm at TSMC for Intel, 8 nm at Samsung for NVIDIA.

The transistor counts reflect different design priorities. The Arc A380E packs 7,200 million transistors into 157 mm², while the RTX A1000 packs 8,700 million transistors into 200 mm². The Intel card achieves higher transistor density at 45.9M per mm², but the NVIDIA card uses its larger die for more compute units.

Ray tracing hardware differs significantly. The Arc A380E has 8 RT cores, while the RTX A1000 has 18 RT cores. Tensor core availability is exclusive to the NVIDIA card: 72 tensor cores are listed for the RTX A1000, while the Arc A380E has none listed. This makes the RTX A1000 the only card of the two with dedicated AI acceleration hardware.

FP16 performance scales differently. The Arc A380E delivers 8.192 TFLOPS with a 2:1 ratio to FP32. The RTX A1000 delivers 6.737 TFLOPS with a 1:1 ratio. This means the Intel card has a higher peak half-precision throughput, but the NVIDIA card maintains consistent throughput across both precisions.

The production and generational context differs as well. The Arc A380E is end-of-life, with its predecessor listed as Xe Graphics and its successor as Battlemage. The RTX A1000 is active, with its predecessor listed as Quadro Turing and its successor as Workstation Ada. The release dates are close: 2024-03-31 for the Intel card and 2024-04-15 for the NVIDIA card.

Where Each One Wins

The NVIDIA RTX A1000 wins in raw compute performance. Its FP32 throughput of 6.737 TFLOPS is 64% higher than the Arc A380E's 4.096 TFLOPS. Its texture rate of 105.3 GTexel/s, while lower than the Intel card's 128.0 GTexel/s, comes with a much higher shading unit count. The 2304 shading units versus 1024 gives the RTX A1000 a substantial advantage in shader-bound workloads. The 8 GB memory capacity and 192.0 GB/s bandwidth also favor the RTX A1000 for larger datasets and textures.

The RTX A1000 also wins on efficiency. Its 50 W TDP is 33% lower than the Arc A380E's 75 W, yet it delivers significantly higher performance. The benchmark data confirms this: the RTX A1000's average score of 34207 and 79th percentile ranking place it well above the Arc A380E's 50th percentile. Its nearest rivals, including the NVIDIA TITAN V and RTX A2000 12 GB, cluster within 0.6% of its score, showing it performs at a high level relative to established cards.

The Intel Arc A380E wins in specific areas. Its pixel rate of 64.00 GPixel/s exceeds the RTX A1000's 46.78 GPixel/s, which indicates faster fill-rate-bound rendering. Its clock speed of 2000 MHz is constant across base and boost, whereas the RTX A1000 varies from 727 MHz to 1462 MHz. The higher memory clock of 1937 MHz with 15.5 Gbps effective speed also favors the Intel card, though the narrower 96-bit bus limits overall bandwidth.

The Arc A380E also wins on display output. It provides four DisplayPort 2.0 connections, which support higher bandwidth than the RTX A1000's four mini-DisplayPort 1.4a connections. For multi-monitor setups with high resolution and refresh rates, the DisplayPort 2.0 standard offers more headroom. The Intel card's FP16 throughput of 8.192 TFLOPS also exceeds the RTX A1000's 6.737 TFLOPS, which may benefit specific half-precision compute workloads.

For ray tracing and AI workloads, the RTX A1000 holds the advantage. Its 18 RT cores versus 8 RT cores gives it more ray tracing hardware. The 72 tensor cores provide dedicated AI acceleration that the Arc A380E completely lacks. For users running neural network inference or training on a workstation GPU, the RTX A1000 is the only option between these two cards.
