Analysis: AMD Radeon Pro Vega II vs AMD Radeon RX 6600 LE
The Verdict
The AMD Radeon Pro Vega II is the decisive winner in every recorded benchmark comparison against the AMD Radeon RX 6600 LE. The database shows two head-to-head tests, and the Pro Vega II wins both with substantial margins. For users prioritizing raw compute throughput in OpenCL and Vulkan workloads, the Pro Vega II is the clear choice based on the data. The RX 6600 LE, while a newer architecture, does not match the older flagship in these specific metrics. The Pro Vega II leads by 43.1% in Geekbench OpenCL and 37.5% in Geekbench Vulkan. Its average benchmark score of 109,617 sits 54.8% above the RX 6600 LE's 70,829. However, the RX 6600 LE remains an active product with a much lower power draw, making it suitable for systems where efficiency and physical footprint are primary concerns. The data suggests that the Pro Vega II is for compute-heavy tasks, while the RX 6600 LE is for mainstream gaming or workstation use where its smaller size and lower power requirements are advantages.
Architecture Differences
The two GPUs come from different architectural generations. The AMD Radeon Pro Vega II uses the Vega 20 chip based on GCN 5.1 architecture, while the AMD Radeon RX 6600 LE uses the Navi 23 chip based on RDNA 2.0. Both are fabricated on a 7 nm process at TSMC, but the transistor counts and die sizes differ. The Pro Vega II has 13,230 million transistors on a 331 mm² die, resulting in a transistor density of 40.0M per mm². The RX 6600 LE has 11,060 million transistors on a 237 mm² die, with a higher density of 46.7M per mm². This indicates the RX 6600 LE packs more transistors per area, reflecting the newer RDNA 2 design.
Memory configurations are starkly different. The Pro Vega II features 32 GB of HBM2 memory on a 4096-bit bus, delivering 825.3 GB/s of bandwidth. The RX 6600 LE has 8 GB of GDDR6 on a 128-bit bus, providing 224.0 GB/s. The Pro Vega II's memory bandwidth is 3.7 times higher, a crucial factor for data-intensive workloads. Clock speeds also differ: the Pro Vega II has a base clock of 1574 MHz and a boost of 1720 MHz, while the RX 6600 LE has a base of 1626 MHz and a much higher boost of 2495 MHz. The RX 6600 LE also lists a game clock of 2045 MHz. Despite the higher clocks on the RX 6600 LE, the Pro Vega II's larger shading unit count (4096 vs 1792) and TMU count (256 vs 112) give it a significant compute advantage. Both have 64 ROPs. The Pro Vega II has no ray tracing cores, while the RX 6600 LE has 28. The RX 6600 LE supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Pro Vega II supports DirectX 12 (12_1) and Vulkan 1.3. The bus interfaces also differ: the Pro Vega II uses Apple MPX, while the RX 6600 LE uses PCIe 4.0 x8.
