AMD Radeon RX 6600 vs AMD Radeon RX 9060 Comparison

Where Each One Wins

The benchmark record splits cleanly along API and workload lines. The AMD Radeon RX 9060 dominates the modern and compute-oriented tests, taking 8 of the 10 head-to-head comparisons. Its wins include 3DMark Steel Nomad DX12, Geekbench OpenCL, Passmark DirectX 10, DirectX 11, DirectX 9, G2D, G3D, and GPU Compute. The RX 9060's most decisive victories come in raw throughput and newer graphics workloads, where its architecture generational leap shows clearly.

The AMD Radeon RX 6600 holds only two wins, but they are not trivial. It beats the RX 9060 in Geekbench Vulkan by a massive 71.3% margin, and it edges out the RX 9060 in Passmark DirectX 12 by 15.9%. These wins suggest that the RX 6600 retains an advantage in specific Vulkan scenarios and in one particular DirectX 12 test, despite being the older product. The RX 6600's average benchmark score of 19036 also sits above the RX 9060's 16014, though this aggregate figure is skewed by the RX 6600's strong Vulkan result and its Geekbench Metal score of 88398, a test the RX 9060 did not run.

If you are targeting legacy DirectX 9 or 10 titles, the RX 9060 is the clear pick, with Passmark DirectX 9 scores of 280 versus 197 and DirectX 10 scores of 104 versus 95. For compute-heavy tasks such as OpenCL workloads, the RX 9060's 88183 score dwarfs the RX 6600's 28850. The RX 9060 also leads in the aggregate G3D score, 17631 to 15096, making it the stronger general-purpose gaming card in most measured scenarios.

Architecture Differences

The two cards come from different generations of AMD's RDNA architecture. The RX 6600 uses RDNA 2.0 on a 7 nm TSMC process, while the RX 9060 uses RDNA 4.0 on a 4 nm TSMC node. The transistor counts reflect this shift: the RX 6600 packs 11,060 million transistors on a 237 mm² die, while the RX 9060 crams 29,700 million transistors into a smaller 199 mm² die. Transistor density jumps from 46.7M per mm² on the RX 6600 to 149.2M per mm² on the RX 9060, a clear sign of the process node advantage.

Both cards feature identical shading unit counts at 1792, the same 112 texture mapping units, the same 64 ROPs, and the same 28 ray tracing cores. Neither card has tensor cores. The memory subsystem is also similar on paper: both have 8 GB of GDDR6 on a 128-bit bus. The difference comes in bandwidth, where the RX 9060's 288.0 GB/s outpaces the RX 6600's 224.0 GB/s thanks to faster memory clocks (2250 MHz or 18 Gbps effective versus 1750 MHz or 14 Gbps effective).

Clock speeds tell a similar story. The RX 9060 has a base clock of 1700 MHz, a game clock of 2400 MHz, and a boost clock of 2990 MHz. The RX 6600 trails with a 1626 MHz base, 2044 MHz game, and 2491 MHz boost. The compute throughput gap is substantial: the RX 9060 delivers 21.43 TFLOPS FP32 and 21.43 TFLOPS FP16 (1:1), while the RX 6600 manages 8.928 TFLOPS FP32 and 17.86 TFLOPS FP16 (2:1). The RX 9060's pixel rate of 191.4 GPixel/s and texture rate of 334.9 GTexel/s both exceed the RX 6600's 159.4 GPixel/s and 279.0 GTexel/s.

The interface also differs. The RX 6600 uses PCIe 4.0 x8, while the RX 9060 steps up to PCIe 5.0 x16. Display outputs vary: the RX 6600 has 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the RX 9060 has 1x HDMI 2.1b and 2x DisplayPort 2.1a. Both cards are dual-slot with a single 8-pin power connector and a 300 W suggested PSU. The RX 9060 is an active product released in 2025, while the RX 6600 is end-of-life and launched in 2021.

Head-to-Head Benchmarks

The most striking gap in the recorded data is in Geekbench OpenCL. The RX 9060 scores 88183, which is 67.3% ahead of the RX 6600's 28850. This is not a small margin; it is a generational chasm in compute performance. The RX 9060's FP32 throughput of 21.43 TFLOPS versus 8.928 TFLOPS explains much of this, but the OpenCL result also reflects the efficiency of the newer architecture.

In 3DMark Steel Nomad DX12, the RX 9060 again dominates with a score of 3322 versus 1492, a 55.1% lead. This modern DX12 test favors the newer card's higher clocks and bandwidth. The RX 9060's boost clock of 2990 MHz versus 2491 MHz and its 288 GB/s memory bandwidth give it a clear edge in sustained GPU-bound workloads.

The RX 6600's one major victory comes in Geekbench Vulkan, where it scores 67623 against the RX 9060's 39476, a 71.3% advantage. This is the largest delta in either direction across all tests. The RX 6600 also wins Passmark DirectX 12, though by a smaller margin: 51 to 44, a 15.9% lead. These two wins suggest that the RX 6600's driver or hardware implementation handles certain Vulkan and DX12 paths more efficiently, despite the RX 9060's raw compute advantage.

In the Passmark suite, the RX 9060 takes the rest. DirectX 11 shows 182 versus 152, a 16.5% lead. DirectX 9 shows 280 versus 197, a 29.6% lead. DirectX 10 shows 104 versus 95, an 8.7% lead. G2D is 1002 versus 889, an 11.3% lead. G3D is 17631 versus 15096, a 14.4% lead. GPU Compute is 9919 versus 6554, a 33.9% lead. Across the board, the RX 9060 wins by margins ranging from 8.7% to 67.3%, with the smaller wins in legacy DX10 and 2D workloads and the larger wins in compute and modern API tests.

The Verdict

The data points to a clear split. If your primary concern is modern gaming, compute workloads, or DirectX 9 through DirectX 11 titles, the AMD Radeon RX 9060 is the stronger choice. It wins 8 of 10 head-to-head comparisons, and its victories include the most demanding tests: 3DMark Steel Nomad DX12 and Geekbench OpenCL. The RX 9060's higher boost clock, doubled FP32 throughput, and 28.6% more memory bandwidth all contribute to its dominance in these areas.

However, the RX 6600 is not without merit. Its 71.3% Vulkan lead and 15.9% DirectX 12 win indicate that specific API paths still favor the older card. If you run Vulkan-based applications or certain DirectX 12 titles that align with the RX 6600's strengths, the RX 6600 may deliver better performance. Its higher average benchmark score of 19036 versus 16014 also reflects its strong showing in Vulkan and Metal tests.

The RX 9060's percentile rank of 59 versus the RX 6600's 63 is interesting: despite winning most head-to-head tests, the RX 9060 sits lower in the all-GPU percentile ranking. This is because the RX 9060's average score is dragged down by its weak Vulkan result, while the RX 6600 benefits from a robust Vulkan and Metal presence. For a buyer, this means the RX 6600 is a specialized tool for Vulkan-heavy workloads, while the RX 9060 is the more versatile card for general use.

Choose the RX 9060 for a balanced, future-proof card that handles compute and modern APIs well. Choose the RX 6600 if your workload is dominated by Vulkan and you can tolerate weaker performance elsewhere. The RX 6600 is end-of-life, so availability may be limited, while the RX 9060 is an active product.
