AMD Radeon Pro W6600X vs Intel Arc Pro A60 Comparison

The AMD Radeon Pro W6600X and Intel Arc Pro A60 are both workstation-oriented graphics cards, but the data places them in very different roles. The W6600X achieves a Geekbench Metal score of 107,342 and sits in the 94th percentile of all GPUs, while the Arc Pro A60 manages 63,485 in Geekbench OpenCL and 57,166 in Geekbench Vulkan, landing in the 88th percentile. Those headline numbers tell a simple story, but the details of what each card does well, how they are built, and who should choose them require a closer look at the recorded specifications and benchmark results.

Where Each One Wins

The AMD Radeon Pro W6600X wins decisively in raw compute performance. Its Geekbench Metal score of 107,342 places it 78.9% ahead of the Intel Arc Pro A60’s OpenCL score of 63,485, and 87.8% ahead of the Arc Pro A60’s Vulkan score of 57,166. The W6600X also outperforms its immediate rivals in the database: it is 0.6% ahead of the AMD Radeon Pro Vega II Duo (106,750), 5.4% ahead of the NVIDIA Quadro RTX 6000 (101,872), and only 2.1% behind the AMD Radeon Pro Vega II (109,617). This card is built for heavy compute workloads, and the benchmark data reflects that.

The Intel Arc Pro A60 wins in memory capacity and interface flexibility. It offers 12 GB of GDDR6 memory compared to the W6600X’s 8 GB, and it uses a 192-bit bus width versus the W6600X’s 128-bit bus. That larger memory pool and wider bus translate to 384.0 GB/s of bandwidth, which is 50% higher than the W6600X’s 256.0 GB/s. The Arc Pro A60 also uses a standard PCIe 4.0 x16 interface, while the W6600X uses Apple MPX, and the Arc Pro A60 has four DisplayPort 2.0 outputs, while the W6600X has no display outputs at all. For tasks that require large datasets in memory or direct display connectivity, the Arc Pro A60 is the clear choice.

The W6600X also wins on clock speeds. Its base clock of 2068 MHz and boost clock of 2479 MHz are far above the Arc Pro A60’s 900 MHz base and 2050 MHz boost. That difference in clocks contributes directly to the W6600X’s higher pixel rate (158.7 GPixel/s vs. 131.2 GPixel/s), texture rate (317.3 GTexel/s vs. 262.4 GTexel/s), and FP32 throughput (10.15 TFLOPS vs. 8.397 TFLOPS). The Arc Pro A60 counters with a lower power draw of 130 W versus 120 W for the W6600X, though the W6600X actually has a lower TDP despite its higher performance, a notable efficiency advantage.

Architecture Differences

The two cards come from different architectural generations and design philosophies. The AMD Radeon Pro W6600X uses the Navi 23 chip built on RDNA 2.0, fabricated on a 7 nm process at TSMC. It contains 11,060 million transistors on a 237 mm² die, giving a transistor density of 46.7 million per square millimeter. The Intel Arc Pro A60 uses the DG2-256 chip based on Xe-HPG architecture, fabricated on a 6 nm process at TSMC. It packs 11,500 million transistors into a 269 mm² die, yielding a density of 42.8 million per square millimeter. The W6600X is therefore slightly smaller and more densely packed, while the Arc Pro A60 uses a larger die with more transistors.

Both cards feature 2048 shading units, 128 texture mapping units, and 64 raster operation units. That is where the similarities end. The W6600X has 32 ray tracing cores, while the Arc Pro A60 has only 16. The W6600X’s FP16 output is 20.31 TFLOPS (2:1 ratio) versus the Arc Pro A60’s 16.79 TFLOPS (2:1 ratio). The W6600X’s generation is listed as Radeon Pro Mac (Navi II Series) with a release date of August 2021, while the Arc Pro A60 is from the Alchemist (Pro Series) generation with a release date of June 2023. The W6600X is marked as end-of-life, while the Arc Pro A60 is active in production.

Memory architecture also differs significantly. The W6600X runs GDDR6 at 2000 MHz with 16 Gbps effective speed on a 128-bit bus, achieving 256.0 GB/s. The Arc Pro A60 also runs GDDR6 at 2000 MHz with 16 Gbps effective speed but on a 192-bit bus, achieving 384.0 GB/s. The W6600X’s smaller bus is a bottleneck for bandwidth, but its higher clocks compensate in compute-bound tasks. The Arc Pro A60’s wider bus gives it a clear advantage in memory-intensive workloads like large texture sets or high-resolution render buffers.

The bus interface and display outputs are another major divide. The W6600X uses Apple MPX and has no display outputs, meaning it is designed for Mac Pro systems where output is handled elsewhere. The Arc Pro A60 uses PCIe 4.0 x16 and provides four DisplayPort 2.0 outputs, making it a drop-in card for standard PC workstations. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is not a distinguishing factor.

Pixel rate is 158.7 GPixel/s versus 131.2 GPixel/s, and texture rate is 317.3 GTexel/s versus 262.4 GTexel/s. FP32 is 10.15 TFLOPS versus 8.397 TFLOPS, and FP16 is 20.31 TFLOPS versus 16.79 TFLOPS.

Power and physical design differ as well. The W6600X has a 120 W TDP, while the Arc Pro A60 has a 130 W TDP. The W6600X is dual-slot, while the Arc Pro A60 is single-slot. Both suggest a 300 W power supply. The W6600X uses Apple MPX bus interface, while the Arc Pro A60 uses PCIe 4.0 x16. Display outputs: none for the W6600X, four DisplayPort 2.0 for the Arc Pro A60.

Head-to-Head Benchmarks

The recorded benchmark data gives one score for the W6600X and two for the Arc Pro A60. There are no direct head-to-head benchmark entries in the database, so the comparison relies on these separate measurements. The W6600X’s Geekbench Metal score of 107,342 is its only recorded benchmark, and it stands far above the Arc Pro A60’s OpenCL score of 63,485 and Vulkan score of 57,166. The gap between the W6600X and the Arc Pro A60’s best score (OpenCL) is 43,857 points, which equates to roughly 69% higher performance. Against the Arc Pro A60’s Vulkan score, the W6600X is ahead by 50,176 points, or about 87.8%.

The W6600X’s percentile ranking of 94 versus the Arc Pro A60’s 88 places the AMD card in a higher overall tier. Looking at the W6600X’s nearest rivals, it sits between the Radeon Pro Vega II (109,617, 2.1% higher) and the Radeon Pro Vega II Duo (106,750, 0.6% lower). The NVIDIA Quadro RTX 6000 trails at 101,872, which is 5.4% behind the W6600X. The Arc Pro A60’s nearest rivals tell a different story: its average score of 60,326 is statistically tied with the NVIDIA GeForce RTX 4090 (60,347, 0% delta) and the AMD Radeon Pro Vega 48 (60,140, 0.3% higher). The AMD Radeon Pro W6600M is 2.5% ahead at 61,896, and the AMD Radeon PRO V710 is 2.8% behind at 58,657.

In practical terms, the W6600X’s benchmark advantage means it handles compute-heavy tasks like rendering, simulation, or GPU-accelerated workloads with significantly more headroom. The Arc Pro A60, while slower in raw scores, offers a wider memory bus and more memory, which can be decisive in tasks that are bandwidth-limited rather than compute-limited. The Arc Pro A60’s Vulkan score of 57,166 is its lowest recorded result, suggesting that its performance varies more across APIs than the W6600X’s single Metal score implies.

The Verdict

The data points to two distinct buyer profiles. The AMD Radeon Pro W6600X is for users who need maximum compute throughput in a Mac ecosystem. Its Apple MPX interface, lack of display outputs, and 94th percentile ranking make it a specialized card for Mac Pro systems where raw FP32 and ray tracing performance matter more than memory capacity or display connectivity. Its 10.15 TFLOPS FP32, 32 ray tracing cores, and 2479 MHz boost clock place it well above the Arc Pro A60 in every compute metric. The 120 W TDP is also lower than the Arc Pro A60’s 130 W, which is remarkable given the performance gap.

The Intel Arc Pro A60 is for users who need a flexible, standard workstation card. Its PCIe 4.0 x16 interface, four DisplayPort 2.0 outputs, and 12 GB memory pool make it a practical choice for general-purpose workstations. The 192-bit bus and 384.0 GB/s bandwidth give it a 50% advantage in memory bandwidth, which matters for large textures, high-resolution frames, or multi-display setups. Its single-slot design and active production status also make it easier to integrate into new builds or existing systems.

The W6600X is end-of-life, while the Arc Pro A60 is active, so long-term availability favors Intel. The W6600X’s average benchmark score of 107,342 versus the Arc Pro A60’s 60,326 shows that the AMD card is in a different performance class. However, the Arc Pro A60’s 12 GB memory and direct display outputs are features the W6600X simply does not offer. If the workload is compute-bound and the system is a Mac Pro, the W6600X is the obvious pick. If the workload is memory-bound, requires display output, or uses a standard PC platform, the Arc Pro A60 is the better fit. Neither card dominates the other across all criteria; the choice depends entirely on the system and the task.
