AMD Radeon RX 6600 LE vs Intel Arc Pro A60 Comparison

The AMD Radeon RX 6600 LE and Intel Arc Pro A60 occupy different corners of the GPU market, but when forced head-to-head, the data is unambiguous: the AMD card wins both benchmark tests, and in one of them, it wins by a landslide. The average benchmark score for the RX 6600 LE is 70,829, placing it in the 91st percentile of all GPUs, while the Arc Pro A60 trails with an average of 60,326 and an 88th percentile rank. Neither card has a launch MSRP listed, and both are currently marked as Active in production.

Head-to-Head Benchmarks

The most striking result comes from the Geekbench Vulkan test, where the AMD Radeon RX 6600 LE scores 72,428 against the Intel Arc Pro A60’s 57,166. That is a 26.7% delta in favor of AMD, a massive gap that suggests the RDNA 2.0 architecture handles Vulkan workloads with far greater efficiency than Intel’s Xe-HPG in this specific configuration. For context, the RX 6600 LE’s nearest rival in average score is the NVIDIA RTX A3000 Mobile at 70,140, a mere 1% behind, which puts the AMD card in the same performance tier as a high-end mobile workstation GPU. The Arc Pro A60, by contrast, sits within 0.3% of the AMD Radeon Pro Vega 48 and is statistically tied with the NVIDIA GeForce RTX 4090, which shows a delta of 0% — though that comparison is based on average scores, not the Vulkan test specifically.

The OpenCL results are closer but still favor AMD. The RX 6600 LE posts 69,229, while the Arc Pro A60 manages 63,485, a 9% advantage for AMD. This is a more modest margin, indicating that in compute-heavy OpenCL tasks, the Intel card is competitive but not quite at the same level. The RX 6600 LE’s OpenCL score is within 1.2% of the NVIDIA Quadro P6000’s 69,986 average, and it is 1.4% ahead of the AMD Radeon Pro WX 8200’s 69,870. On the Intel side, the Arc Pro A60’s OpenCL performance puts it 2.5% behind the AMD Radeon Pro W6600M’s 61,896 and 2.8% ahead of the AMD Radeon PRO V710’s 58,657. Across both tests, the RX 6600 LE wins 2-0, with a combined average score of 70,829 versus 60,326 — a 17.4% gap that underscores a clear performance hierarchy.

Architecture Differences

The two cards are built on fundamentally different silicon. The AMD Radeon RX 6600 LE uses the Navi 23 chip based on RDNA 2.0 architecture, manufactured on TSMC’s 7 nm process. It packs 11,060 million transistors on a 237 mm² die, yielding a transistor density of 46.7 million per square millimeter. The Intel Arc Pro A60, meanwhile, uses the DG2-256 chip with Xe-HPG architecture, built on TSMC’s newer 6 nm process. It has slightly more transistors at 11,500 million but on a larger 269 mm² die, resulting in a lower density of 42.8 million per square millimeter. The process node advantage does not translate into a density advantage for Intel, which is a notable engineering data point.

Clock speeds diverge sharply. AMD’s card runs at a 1626 MHz base clock and boosts to 2495 MHz, with a game clock of 2045 MHz. Intel’s base clock is just 900 MHz, though the boost reaches 2050 MHz — still 445 MHz below the AMD boost. Memory clocks also differ: AMD uses 1750 MHz (14 Gbps effective), while Intel runs at 2000 MHz (16 Gbps effective). The memory subsystems are designed differently: the RX 6600 LE has 8 GB of GDDR6 on a 128-bit bus delivering 224.0 GB/s of bandwidth, whereas the Arc Pro A60 has 12 GB on a 192-bit bus for 384.0 GB/s — a 71% bandwidth advantage for Intel.

Compute resources tell a mixed story. Intel has more shading units (2048 vs 1792), more texture mapping units (128 vs 112), and the same number of ROPs (64). However, AMD has more ray tracing cores (28 vs 16). The raw throughput numbers favor AMD: 8.942 TFLOPS FP32 versus 8.397 TFLOPS, and 17.88 TFLOPS FP16 versus 16.79 TFLOPS. Pixel and texture rates also go AMD’s way, with 159.7 GPixel/s versus 131.2 GPixel/s and 279.4 GTexel/s versus 262.4 GTexel/s. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical.

FAQ

A: The AMD Radeon RX 6600 LE scores 70,829 on average, compared to the Intel Arc Pro A60’s 60,326. The AMD card also ranks in the 91st percentile of all GPUs, while Intel sits in the 88th.

Q: How large is the performance gap in the Vulkan test?

A: The RX 6600 LE scores 72,428 in Geekbench Vulkan, which is 26.7% higher than the Arc Pro A60’s 57,166. This is the single largest margin in the head-to-head comparison.

Q: Does the Intel card have any advantages in memory capacity or bandwidth?

A: Yes. The Arc Pro A60 has 12 GB of GDDR6 memory on a 192-bit bus with 384.0 GB/s bandwidth. The RX 6600 LE has 8 GB on a 128-bit bus with 224.0 GB/s. Intel’s bandwidth is roughly 71% higher.

Q: Which card has more ray tracing cores?

A: The AMD Radeon RX 6600 LE has 28 ray tracing cores, while the Intel Arc Pro A60 has 16. AMD also has a higher boost clock at 2495 MHz versus Intel’s 2050 MHz.

Q: Are both cards the same physical size?

A: No. The AMD card is dual-slot with dimensions of 190 mm length, 110 mm height, and 40 mm width, and requires a 1x 8-pin power connector. The Intel card is single-slot, but its length, height, and width are not listed, and it has no power connector specified.

Q: What is the transistor count difference?

A: The Intel Arc Pro A60 has 11,500 million transistors, slightly more than the AMD card’s 11,060 million. However, AMD achieves a higher density of 46.7M per mm² versus Intel’s 42.8M per mm².

The Verdict

The data is decisive: the AMD Radeon RX 6600 LE is the faster card in both compute benchmarks, with a 9% OpenCL win and a 26.7% Vulkan win. Its average score of 70,829 places it 17.4% above the Arc Pro A60’s 60,326. If the priority is raw benchmark performance, the AMD card is the clear choice. The Intel card’s advantages — 12 GB memory, 384.0 GB/s bandwidth, single-slot design — do not translate into higher scores in the tests recorded. The RX 6600 LE also has a higher boost clock (2495 MHz vs 2050 MHz), more ray tracing cores (28 vs 16), and higher FP32 throughput (8.942 TFLOPS vs 8.397 TFLOPS). Intel’s 6 nm process and higher memory bandwidth are notable, but they do not overcome AMD’s execution efficiency. For users who prioritize Geekbench scores, the AMD card wins outright.

Where Each One Wins

The AMD Radeon RX 6600 LE wins in every measured benchmark category. In Geekbench OpenCL, it scores 69,229 versus 63,485, a 9% margin that shows solid compute capability. In Geekbench Vulkan, the 26.7% advantage at 72,428 versus 57,166 is the standout result, making it the superior choice for Vulkan-based applications. The AMD card also leads in raw throughput metrics like FP32 (8.942 TFLOPS vs 8.397 TFLOPS) and pixel rate (159.7 GPixel/s vs 131.2 GPixel/s). It has a higher boost clock and more ray tracing cores, making it better suited for ray-traced workloads.

The Intel Arc Pro A60 wins on memory capacity and bandwidth — 12 GB and 384.0 GB/s versus 8 GB and 224.0 GB/s — which could benefit workloads with large datasets that fit in VRAM. It also offers a single-slot form factor, which is advantageous for space-constrained systems, and supports DisplayPort 2.0 outputs, a newer standard than AMD’s DisplayPort 1.4a. Intel’s card has more shading units (2048 vs 1792) and TMUs (128 vs 112), but these do not translate into benchmark wins. Its lower base clock of 900 MHz likely hampers sustained performance. For users who need maximum memory bandwidth or a compact single-slot card, the Arc Pro A60 has a niche, but for overall benchmark performance, the RX 6600 LE is the definitive winner.
