Intel Arc A550M vs NVIDIA RTX A6000 Comparison

The Intel Arc A550M and NVIDIA RTX A6000 represent two fundamentally different extremes of the GPU market, and the benchmark data reflects that divergence clearly. The data shows the RTX A6000 winning both head-to-head tests decisively, with a 74.3% lead in Geekbench OpenCL and a 69.9% lead in Geekbench Vulkan. However, the Arc A550M sits at the 86th percentile of all GPUs while the RTX A6000 sits at the 84th, a counterintuitive result that comes from the Arc’s narrower but more consistent benchmark profile. The verdict is straightforward: the RTX A6000 is the performance king by a wide margin, but the Arc A550M is a far more power-efficient mobile option that still lands in the top tier of the database.

The Verdict

The data makes one thing clear: the NVIDIA RTX A6000 is the choice for anyone needing maximum raw compute throughput. Its Geekbench OpenCL score of 193,937 is nearly four times the Arc A550M’s 49,894, and its Vulkan score of 164,462 more than triples the Arc’s 49,580. In the head-to-head comparison, the RTX A6000 wins 2-0, with deltas of -74.3% and -69.9% in its favor. This is a workstation-class card with 38.71 TFLOPS of FP32 performance, and the benchmark results reflect that massive computational advantage.

The Intel Arc A550M, by contrast, is a mobile-first part with a 60 W TDP that still manages to hold its own in the percentile rankings. Its average benchmark score of 49,737 places it just 0.4% behind the NVIDIA GeForce RTX 5070 Ti and 0.5% behind the AMD Radeon RX Vega 64, both of which are far larger desktop cards. The Arc also beats the AMD Radeon RX 6800 XT by 2.6%, a remarkable result for a chip with only 8 GB of memory and a 128-bit bus. For users who need a capable GPU in a thin-and-light laptop, the Arc A550M is the clear pick — it delivers top-tier performance at a fraction of the power draw.

The RTX A6000, meanwhile, carries a 300 W TDP and requires a 700 W suggested PSU, making it a desktop-only solution. Its 48 GB of GDDR6 memory and 768.0 GB/s bandwidth are unmatched in this comparison, and its 84 RT cores and 336 tensor cores position it for professional workloads like rendering and AI inference. The verdict, strictly from the data, is that the RTX A6000 is for professionals who need uncompromised compute, while the Arc A550M is for mobile users who want near-desktop performance in a 60 W package.

Architecture Differences

The two GPUs come from entirely different architectural lineages. The Intel Arc A550M is built on the Xe-HPG architecture, specifically the DG2-512 chip, and belongs to the Alchemist generation for mobile. It uses a 6 nm process from TSMC, packing 21,700 million transistors into a 406 mm² die, yielding a transistor density of 53.4 million per square millimeter. The NVIDIA RTX A6000, in contrast, uses the Ampere architecture with the GA102 chip, fabricated on Samsung’s 8 nm process. It packs 28,300 million transistors into a much larger 628 mm² die, giving a lower density of 45.1 million per square millimeter.

The core configurations differ dramatically. The Arc A550M has 2048 shading units, 128 texture mapping units, and 64 raster output units, along with 16 ray tracing cores but no dedicated tensor cores. The RTX A6000 brings 10,752 shading units, 336 TMUs, and 112 ROPs, with 84 RT cores and 336 tensor cores. That is a 5.25x advantage in shading units and a 5.25x advantage in RT cores, which explains the massive benchmark disparity.

Memory architecture is another major divider. The Arc uses 8 GB of GDDR6 on a 128-bit bus, delivering 224.0 GB/s of bandwidth. The RTX A6000 has 48 GB of GDDR6 on a 384-bit bus, providing 768.0 GB/s — a 3.4x bandwidth advantage. Clock speeds also favor NVIDIA: the RTX A6000 runs at a base of 1410 MHz and boosts to 1800 MHz, while the Arc is clocked at 900 MHz base and 2050 MHz boost. The Arc’s higher boost clock partially compensates for its lower core count, but the sheer scale of the RTX A6000’s silicon is overwhelming.

Both cards support the same API set — DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 — so software compatibility is not a differentiator. The RTX A6000’s tensor cores are the key architectural feature the Arc lacks, making the NVIDIA card the only option here for workloads that leverage tensor operations. The Arc’s smaller die and lower transistor count also mean it runs on a more advanced process node, which contributes to its dramatically lower power consumption.

Head-to-Head Benchmarks

The only two shared benchmarks in the database are Geekbench OpenCL and Geekbench Vulkan, and the RTX A6000 wins both without contest. In Geekbench OpenCL, the RTX A6000 scores 193,937 against the Arc A550M’s 49,894, a delta of -74.3%. That means the RTX A6000 delivers roughly 3.9x the OpenCL compute performance. This is the kind of gap that reflects the RTX A6000’s 38.71 TFLOPS FP32 rating compared to the Arc’s 8.397 TFLOPS — a 4.6x theoretical difference that translates into a 3.9x real-world result.

In Geekbench Vulkan, the margin narrows slightly but remains overwhelming. The RTX A6000 scores 164,462 against the Arc’s 49,580, a delta of -69.9%. The RTX A6000 still delivers 3.3x the Vulkan performance. The fact that the Vulkan gap is smaller than the OpenCL gap suggests the Arc’s architecture handles Vulkan’s lower-level API relatively better, but the absolute numbers still place the RTX A6000 in a different performance class entirely.

The Arc A550M’s individual benchmark scores are respectable in absolute terms — 49,894 in OpenCL and 49,580 in Vulkan are not far apart, indicating consistent performance across different API workloads. The RTX A6000, however, shows a wider internal spread, with its OpenCL score 17.9% higher than its Vulkan score. This suggests the RTX A6000 is more optimized for OpenCL-style compute workloads, which aligns with its workstation positioning. For users comparing these two, the head-to-head data leaves no ambiguity: the RTX A6000 is the superior performer by a factor of three or more in every shared test.
