AMD Radeon Pro 5700 vs AMD Radeon RX 6600 Comparison

The AMD Radeon RX 6600 and AMD Radeon Pro 5700 are both end-of-life 7 nm GPUs from AMD, but they target different worlds. The RX 6600 is a RDNA 2.0 consumer card built for gaming and general use, while the Pro 5700 is a RDNA 1.0 workstation part designed for Apple Mac systems, with no display outputs. Benchmark data shows the RX 6600 wins 9 out of 10 head-to-head tests, with an average benchmark score of 19036 against the Pro 5700’s 18189. However, the Pro 5700 holds a significant lead in OpenCL compute, making the choice between them depend entirely on your software stack and platform.

The Verdict

Choose the AMD Radeon RX 6600 if you need a conventional graphics card for gaming, DirectX workloads, or any task that benefits from raw rasterization performance. It wins decisively in the majority of benchmarks, including a 94.9% lead in Passmark DirectX 11 (152 vs 78) and a 30.3% lead in Passmark G3D (15096 vs 11583). The RX 6600 also has a higher percentile ranking, sitting at the 63rd percentile versus the Pro 5700’s 62nd, and it comes with a launch MSRP of 329 USD.

Choose the AMD Radeon Pro 5700 only if you are working in an Apple Mac environment where the card’s integrated design (IGP slot width, no power connectors, no display outputs) is required, and your software relies heavily on OpenCL compute. The Pro 5700 delivers a 45.3% advantage in Geekbench OpenCL (52787 vs 28850), which is its single head-to-head victory. For anyone building a standard PC, the RX 6600 is the clear data-driven pick, as it outperforms the Pro 5700 in every other measured category, including a 47% lead in Geekbench Metal (88398 vs 60126).

Architecture Differences

The two cards are built on different RDNA generations. The RX 6600 uses the Navi 23 chip with RDNA 2.0 architecture, while the Pro 5700 uses the Navi 10 chip with RDNA 1.0. Both are fabricated by TSMC on a 7 nm process, but the transistor counts and die sizes differ. The RX 6600 packs 11,060 million transistors on a 237 mm² die, giving it a transistor density of 46.7 million per mm². The Pro 5700 has 10,300 million transistors on a slightly larger 251 mm² die, resulting in a lower density of 41.0 million per mm².

The most critical architectural difference is the presence of ray tracing cores. The RX 6600 includes 28 ray tracing cores, while the Pro 5700 has none. This is a direct consequence of RDNA 2.0’s hardware ray tracing support, which RDNA 1.0 lacks. Additionally, the RX 6600 supports DirectX 12 Ultimate (12_2), whereas the Pro 5700 is limited to DirectX 12 (12_1). Both cards support OpenGL 4.6 and Vulkan 1.4, but the RX 6600’s newer architecture gives it a feature-set advantage for modern games and applications.

Clock speeds also reflect the architectural gap. The RX 6600 runs at a base clock of 1626 MHz, a game clock of 2044 MHz, and a boost clock of 2491 MHz. The Pro 5700 is far more conservative, with a base clock of 1243 MHz and a boost clock of 1350 MHz, and no game clock listed. Memory clocks differ as well: the RX 6600 uses 1750 MHz (14 Gbps effective) GDDR6, while the Pro 5700 runs at 1500 MHz (12 Gbps effective). These clock differences translate into a massive pixel rate advantage for the RX 6600, which hits 159.4 GPixel/s versus the Pro 5700’s 86.40 GPixel/s.

Where Each One Wins

The RX 6600 wins in nearly every scenario where graphics output is needed. It has display outputs (1x HDMI 2.1, 3x DisplayPort 1.4a), PCIe 4.0 x8 interface, and a dual-slot cooler with a single 8-pin power connector. Its performance lead is most pronounced in DirectX 11, where it is 94.9% ahead, and in DirectX 9, where it leads by 37.8%. It also wins in Vulkan by 31.8% (67623 vs 51289), which is relevant for modern cross-platform games. The RX 6600’s FP32 compute of 8.928 TFLOPS is substantially higher than the Pro 5700’s 6.221 TFLOPS, and its texture rate of 279.0 GTexel/s dwarfs the Pro 5700’s 194.4 GTexel/s.

The Pro 5700 wins only in Geekbench OpenCL, where it scores 52787 against the RX 6600’s 28850. This 45.3% advantage suggests that OpenCL-specific compute workloads, common in certain professional applications, run significantly better on the older RDNA 1.0 architecture. The Pro 5700 also has a wider 256-bit memory bus and higher memory bandwidth of 384.0 GB/s, compared to the RX 6600’s 128-bit bus and 224.0 GB/s. This bandwidth advantage may help in memory-bound compute tasks, even though the RX 6600 wins in the overall Passmark GPU compute test by 32.1% (6554 vs 4961). For gaming, the Pro 5700 is effectively non-viable as a standalone card due to its IGP slot width and lack of display outputs.

Head-to-Head Benchmarks

The largest win for the RX 6600 comes in Passmark DirectX 11, where it scores 152 versus the Pro 5700’s 78, a 94.9% difference. This is followed by a 47% lead in Geekbench Metal (88398 vs 60126) and a 37.8% lead in Passmark DirectX 9 (197 vs 143). In Passmark DirectX 10, the RX 6600 leads 95 to 71, a 33.8% margin. The RX 6600 also wins Passmark G3D by 30.3% (15096 vs 11583) and Passmark GPU compute by 32.1% (6554 vs 4961). In Vulkan, the RX 6600 scores 67623 against 51289, a 31.8% advantage. Even in Passmark G2D, the RX 6600 leads by 10.4% (889 vs 805), and in DirectX 12, it wins by a slim 6.3% (51 vs 48).

The Pro 5700 takes a single victory in Geekbench OpenCL, scoring 52787 versus the RX 6600’s 28850. This 45.3% delta is the only test where the Pro 5700 leads, and it is a substantial one. This result is notable because it shows that despite losing in aggregate performance, the Pro 5700 has a specific compute advantage that could be decisive for OpenCL-based applications. The RX 6600’s wins are spread across graphics APIs (DirectX 9, 10, 11, 12, Vulkan, Metal) and general compute, while the Pro 5700’s single win is isolated to one compute API.

Specification Differences

The two cards differ in nearly every core specification except memory size (both 8 GB GDDR6), process node (both 7 nm TSMC), and TDP (132 W vs 130 W). The RX 6600 has 1792 shading units, 112 texture mapping units, and 64 ROPs, while the Pro 5700 has 2304 shading units, 144 TMUs, and 64 ROPs. Despite having more shading units and TMUs, the Pro 5700’s much lower clocks (1350 MHz boost vs 2491 MHz boost) result in lower performance. The RX 6600 has 28 ray tracing cores; the Pro 5700 has none.

Clock speeds are a major differentiator: the RX 6600 has a base clock of 1626 MHz and boost of 2491 MHz, while the Pro 5700 is at 1243 MHz base and 1350 MHz boost. Memory clocks are 1750 MHz (14 Gbps effective) for the RX 6600 and 1500 MHz (12 Gbps effective) for the Pro 5700. The memory bus width differs (128-bit vs 256-bit), giving the Pro 5700 higher bandwidth (384.0 GB/s vs 224.0 GB/s). Pixel rate is 159.4 GPixel/s for the RX 6600 versus 86.40 GPixel/s for the Pro 5700, and texture rate is 279.0 GTexel/s versus 194.4 GTexel/s. FP32 compute is 8.928 TFLOPS versus 6.221 TFLOPS, and FP16 is 17.86 TFLOPS versus 12.44 TFLOPS (both 2:1).

Physical and interface specs also diverge. The RX 6600 is a dual-slot card with a 1x 8-pin power connector and PCIe 4.0 x8 interface; the Pro 5700 is an IGP with no power connectors and PCIe 4.0 x16. The RX 6600 has 1x HDMI 2.1 and 3x DisplayPort 1.4a outputs; the Pro 5700 has no outputs. DirectX support is 12 Ultimate (12_2) for the RX 6600 versus 12 (12_1) for the Pro 5700, though both support OpenGL 4.6 and Vulkan 1.4. The RX 6600 measures 190 mm in length, 110 mm in height, and 40 mm in width, while the Pro 5700 has no listed dimensions. The RX 6600 was released in 2021 with a launch MSRP of 329 USD; the Pro 5700 was released in 2020 with no MSRP listed.
