AMD Radeon PRO W7600 vs AMD Radeon RX 6600 LE Comparison

AMD Radeon PRO W7600 vs AMD Radeon RX 6600 LE pits a professional workstation card built on RDNA 3.0 against a consumer gaming card based on RDNA 2.0. Both share 8 GB of GDDR6 memory on a 128-bit bus, but the data shows a decisive performance gap. The PRO W7600 wins both head-to-head benchmark tests, with an average benchmark score of 87108 versus 70829 for the RX 6600 LE — a difference of roughly 23%. The PRO W7600 also sits at the 93rd percentile among all GPUs, while the RX 6600 LE lands at the 91st percentile, confirming that the professional card holds a clear edge in raw compute.

Head-to-Head Benchmarks

The most lopsided result comes from Geekbench Vulkan, where the AMD Radeon PRO W7600 scores 92688 against the RX 6600 LE’s 72428. That is a 28% advantage for the professional card, a massive margin that reflects the W7600’s architectural advantages. In OpenCL, the gap narrows but remains substantial: the W7600 posts 81528 while the RX 6600 LE manages 69229, a 17.8% lead. Both tests favor the same winner, and there is no benchmark in the data where the RX 6600 LE pulls ahead.

The delta between the two cards is not just a matter of clock speeds. The PRO W7600 delivers 19.99 TFLOPS of FP32 compute, while the RX 6600 LE offers only 8.942 TFLOPS — the professional card is more than twice as fast in raw floating-point throughput. Pixel rate is close, with the W7600 at 156.2 GPixel/s versus 159.7 GPixel/s for the RX 6600 LE, but texture rate favors the W7600 at 312.3 GTexel/s versus 279.4 GTexel/s. The shading unit count also diverges: 2048 on the W7600 versus 1792 on the RX 6600 LE, and the W7600 has 128 TMUs to the RX 6600 LE’s 112, while both have 64 ROPs.

Memory bandwidth tells a similar story. The PRO W7600’s GDDR6 runs at 2250 MHz (18 Gbps effective), yielding 288.0 GB/s, whereas the RX 6600 LE’s memory is clocked at 1750 MHz (14 Gbps effective) for 224.0 GB/s. That is a 28.6% bandwidth advantage for the W7600, which directly supports its higher compute throughput. The boost clocks are nearly identical — 2440 MHz for the W7600 versus 2495 MHz for the RX 6600 LE — but the W7600’s higher base clock of 1720 MHz versus 1626 MHz gives it a steadier performance floor.

In context, the PRO W7600’s average score of 87108 places it just 0.4% behind the NVIDIA Quadro GP100 (87445) and 4.4% behind the RTX A4500 Mobile (91134). The RX 6600 LE, by contrast, sits 1% above the RTX A3000 Mobile (70140) and 1.2% above the Quadro P6000 (69986). The W7600 is clearly in a higher performance tier, and its nearest rivals are all professional or workstation-class GPUs, whereas the RX 6600 LE competes with older Quadro and mobile workstation parts.

The Verdict

The data is unambiguous: the AMD Radeon PRO W7600 is the faster card in every measured benchmark. It wins both head-to-head tests, delivers roughly 2.2 times the FP32 throughput, and offers 28.6% more memory bandwidth. For anyone prioritizing raw compute performance in OpenCL or Vulkan workloads, the PRO W7600 is the correct choice. Its 93rd percentile ranking versus the RX 6600 LE’s 91st percentile reinforces that this is not a marginal win — it is a tier above.

The RX 6600 LE is not without merit, but its strengths lie elsewhere. It is shorter at 190 mm versus 241 mm, and it uses a dual-slot cooler compared to the W7600’s single-slot design. Its power draw is nearly identical at 132 W versus 130 W, and both require a 300 W power supply. However, the RX 6600 LE’s lower compute scores — 69229 in OpenCL and 72428 in Vulkan — place it closer to mobile workstation GPUs like the RTX A3000 Mobile, which it beats by just 1%. The RX 6600 LE also has a lower transistor density at 46.7M transistors per mm² versus the W7600’s 65.2M, despite being built on a larger 237 mm² die versus 204 mm².

Who should pick the RX 6600 LE? Only those who need a compact, dual-slot card with a slightly higher boost clock and do not require the W7600’s compute headroom. But from a pure performance standpoint, the PRO W7600 dominates. It offers 28% higher Vulkan scores, 17.8% higher OpenCL scores, and a superior memory subsystem. The professional card is also built on a newer 6 nm process versus 7 nm, which explains its higher transistor density despite a smaller die. There is no benchmark in the data where the RX 6600 LE wins, so the verdict is straightforward: the PRO W7600 is the superior GPU.

Specification Differences

The two cards differ in nearly every core specification. The PRO W7600 uses the Navi 33 chip on a 6 nm process, while the RX 6600 LE uses Navi 23 on a 7 nm process. Transistor counts differ: 13,300 million for the W7600 versus 11,060 million for the RX 6600 LE, though the W7600’s die is smaller at 204 mm² versus 237 mm². This yields a transistor density of 65.2M per mm² for the W7600 versus 46.7M for the RX 6600 LE.

Shading units are 2048 on the W7600 versus 1792 on the RX 6600 LE. TMUs are 128 versus 112, while ROPs are identical at 64. The W7600 has 32 ray tracing cores versus 28 on the RX 6600 LE. Base clocks are 1720 MHz versus 1626 MHz, boost clocks are 2440 MHz versus 2495 MHz, and the RX 6600 LE also lists a game clock of 2045 MHz. Memory speed is 2250 MHz (18 Gbps effective) versus 1750 MHz (14 Gbps effective), giving bandwidth of 288.0 GB/s versus 224.0 GB/s.

Power draw is close: 130 W for the W7600 versus 132 W for the RX 6600 LE. However, the W7600 uses a single 6-pin power connector and is a single-slot card, while the RX 6600 LE requires a single 8-pin connector and is dual-slot. Both use PCIe 4.0 x8, but the W7600 offers 4x DisplayPort 2.1 outputs, whereas the RX 6600 LE has 1x HDMI 2.1 and 3x DisplayPort 1.4a. Dimensions also differ: the W7600 is 241 mm long and 115 mm high, while the RX 6600 LE is 190 mm long and 110 mm high, with a 40 mm width.

Architecture Differences

The architectural split is clear: the PRO W7600 is built on RDNA 3.0 with the codename "Hotpink Bonefish," while the RX 6600 LE uses RDNA 2.0 with no codename listed. This generational gap is reflected in the process node — 6 nm for the W7600 versus 7 nm for the RX 6600 LE — both fabricated by TSMC. The W7600 belongs to the Radeon Pro Navi generation (Navi III Series), while the RX 6600 LE is part of the Navi II (RX 6000) generation.

Ray tracing cores are more numerous on the W7600 (32 versus 28), and the shading unit count is higher (2048 versus 1792). The W7600 also features a higher transistor density at 65.2M per mm², which is a direct result of the smaller 6 nm node. The RX 6600 LE has a larger die at 237 mm² but packs fewer transistors (11,060 million versus 13,300 million), indicating a less efficient design.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The W7600’s FP16 performance is 39.98 TFLOPS (2:1 ratio), while the RX 6600 LE achieves 17.88 TFLOPS — again, the W7600 is more than double. The RX 6600 LE lists a predecessor of "Navi" and a successor of "Navi III," while the W7600’s predecessor is "Radeon Pro Vega" with no successor listed. Both cards are currently marked as Active in production, with the W7600 releasing on 2023-08-02 and the RX 6600 LE on 2023-12-07. The W7600 has a launch MSRP of 599 USD.
