AMD Radeon Pro W6600X vs NVIDIA CMP 30HX Comparison

Head-to-Head Benchmarks

The recorded data for these two cards comes from different benchmark suites, which makes a direct apples-to-apples comparison impossible. The AMD Radeon Pro W6600X has a single recorded result in Geekbench Metal, scoring 107,342 points. The NVIDIA CMP 30HX has two recorded results: 65,199 in Geekbench OpenCL and 62,484 in Geekbench Vulkan. With no overlapping test entries in the database, the head-to-head benchmark section is empty, and neither card logs a win against the other in a shared workload.

That said, the available numbers still paint a clear picture of relative positioning. The Radeon Pro W6600X lands in the 94th percentile of all GPUs in the database, while the CMP 30HX sits in the 89th percentile. The AMD card’s average benchmark score of 107,342 towers over the CMP 30HX’s average of 63,842, a gap of roughly 68 percent. Even taking the CMP 30HX’s best recorded result, its OpenCL score of 65,199, the Radeon Pro W6600X still leads by more than 64 percent.

Looking at the nearest rivals for each card reinforces this separation. The Radeon Pro W6600X sits within 3.1 percent of the AMD Radeon PRO W7900 (which scores 110,725) and within 2.1 percent of the AMD Radeon Pro Vega II (109,617). It also edges out the AMD Radeon Pro Vega II Duo by 0.6 percent (106,750) and beats the NVIDIA Quadro RTX 6000 by 5.4 percent (101,872). These are close contests at the top end of the database. Meanwhile, the CMP 30HX trades blows with mid-range cards: it is essentially tied with the AMD Radeon RX 9060 XT LP (63,830, a 0 percent delta), the AMD Radeon RX 7600M (63,775, a 0.1 percent delta), and the AMD Radeon Pro Vega 56 (63,693, a 0.2 percent delta). The only rival it trails is the AMD Radeon Pro WX 9100 (64,212, a 0.6 percent deficit).

The data shows that the Radeon Pro W6600X operates in a different performance tier entirely. Its score is not merely higher; it is competitive with workstation flagships, while the CMP 30HX is bracketed by mobile and low-power desktop parts. In any shared workload, the AMD card would be expected to deliver dramatically higher throughput, though the database does not contain a direct test to confirm this.

The Verdict

The data supports a straightforward choice for most users. The AMD Radeon Pro W6600X is the stronger card by every recorded metric. Its average score of 107,342 places it near workstation-class parts like the Radeon PRO W7900 and Radeon Pro Vega II, and it outperforms the NVIDIA Quadro RTX 6000 by 5.4 percent. The CMP 30HX, with an average of 63,842, sits in a completely different performance class, trading blows with the Radeon RX 7600M and Radeon Pro Vega 56.

For anyone seeking raw compute performance, the Radeon Pro W6600X is the only rational pick from the recorded data. Its Geekbench Metal score alone is over 64 percent higher than the CMP 30HX’s best OpenCL result. The CMP 30HX does not come close in any available measurement.

The CMP 30HX is a niche product. It was built for mining, as its name and generation label indicate, and its database scores reflect a mid-range GPU. If the workload is specifically OpenCL or Vulkan on a Turing architecture, it may serve a purpose, but the numbers do not show any scenario where it matches the AMD card’s output.

Specification Differences

The two cards diverge sharply across nearly every core specification. The AMD Radeon Pro W6600X uses a Navi 23 chip on the RDNA 2.0 architecture, built on a 7 nm process at TSMC. The NVIDIA CMP 30HX uses a TU116 chip on the Turing architecture, built on a 12 nm process, also at TSMC. The Radeon Pro W6600X packs 11,060 million transistors on a 237 mm² die, giving a transistor density of 46.7 million per mm². The CMP 30HX has 6,600 million transistors on a 284 mm² die, with a density of 23.2 million per mm². The AMD card is the denser chip by a wide margin.

Clock speeds tell a similar story. The Radeon Pro W6600X runs at a base of 2068 MHz and boosts to 2479 MHz. The CMP 30HX runs at 1530 MHz base and 1785 MHz boost. Memory clocks also differ: the Radeon Pro W6600X uses 2000 MHz (16 Gbps effective), while the CMP 30HX uses 1750 MHz (14 Gbps effective).

Memory configurations are distinct. The Radeon Pro W6600X has 8 GB of GDDR6 on a 128-bit bus, delivering 256.0 GB/s of bandwidth. The CMP 30HX has 6 GB of GDDR6 on a 192-bit bus, delivering 336.0 GB/s of bandwidth. Despite the smaller capacity, the CMP 30HX offers higher raw bandwidth due to its wider bus.

Compute resources differ as well. The Radeon Pro W6600X has 2,048 shading units, 128 TMUs, 64 ROPs, and 32 ray tracing cores. The CMP 30HX has 1,408 shading units, 88 TMUs, and 48 ROPs, with no ray tracing cores listed. The AMD card’s pixel rate is 158.7 GPixel/s versus 85.68 GPixel/s for the NVIDIA card, and its texture rate is 317.3 GTexel/s versus 157.1 GTexel/s. FP32 throughput is 10.15 TFLOPS for AMD and 5.027 TFLOPS for NVIDIA, roughly a two-to-one ratio. FP16 figures follow the same pattern: 20.31 TFLOPS for AMD versus 10.05 TFLOPS for NVIDIA, both at a 2:1 ratio.

Power and connectivity also diverge. The Radeon Pro W6600X is rated at 120 W TDP, while the CMP 30HX is rated at 125 W. Both suggest a 300 W power supply. The AMD card uses an Apple MPX bus interface and has no display outputs, while the CMP 30HX uses a PCIe 1.0 x4 interface, has a single 8-pin power connector, and also has no display outputs. The CMP 30HX has recorded dimensions: 229 mm long, 111 mm high, and 35 mm wide. The Radeon Pro W6600X has no recorded dimensions. Both are dual-slot cards.

API support differs at the DirectX level. The Radeon Pro W6600X supports DirectX 12 Ultimate (12_2), while the CMP 30HX supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. Release dates are close: the Radeon Pro W6600X launched on 2021-08-02, and the CMP 30HX launched on 2021-02-24. Both are end-of-life products. The Radeon Pro W6600X has a launch MSRP of 699 USD, and the CMP 30HX has a launch MSRP of 799 USD.

Architecture Differences

The architectural gap is fundamental. The Radeon Pro W6600X is built on RDNA 2.0, a modern graphics architecture from AMD, while the CMP 30HX is built on NVIDIA’s Turing architecture, which predates it. The manufacturing process reflects this: 7 nm for AMD versus 12 nm for NVIDIA. The AMD chip packs nearly 1.7 times the transistors onto a smaller die, resulting in a transistor density of 46.7 million per mm² versus 23.2 million per mm² for the NVIDIA chip.

The Radeon Pro W6600X belongs to the Radeon Pro Mac (Navi II Series) generation, indicating a focus on Apple Mac workstation environments. The CMP 30HX belongs to the Mining GPUs generation, indicating a purpose-built design for cryptocurrency mining. This explains the lack of display outputs on both cards, but the AMD card’s Apple MPX bus interface suggests integration into Mac Pro systems, while the CMP 30HX’s PCIe 1.0 x4 interface is unusual and likely tailored to mining rigs.

The Radeon Pro W6600X includes 32 ray tracing cores, a feature entirely absent from the CMP 30HX’s specification list. This gives the AMD card hardware support for ray-traced workloads, which the NVIDIA card cannot accelerate. The Turing architecture normally supports ray tracing, but the TU116 chip in the CMP 30HX does not list RT cores in the database, so this specific implementation appears to omit them.

The shading unit count also reflects architectural priorities. The Radeon Pro W6600X has 2,048 shading units, 128 TMUs, and 64 ROPs, while the CMP 30HX has 1,408 shading units, 88 TMUs, and 48 ROPs. The AMD card’s higher counts drive its pixel rate of 158.7 GPixel/s and texture rate of 317.3 GTexel/s, both roughly double the NVIDIA card’s figures.

Where Each One Wins

The Radeon Pro W6600X wins in every category where the database has comparable data. It has the higher average benchmark score, the higher percentile ranking, and the stronger nearest-rival comparisons. Its 10.15 TFLOPS of FP32 performance is double the CMP 30HX’s 5.027 TFLOPS. Its FP16 performance of 20.31 TFLOPS likewise doubles the NVIDIA card’s 10.05 TFLOPS. The AMD card also has more shading units, TMUs, ROPs, and the only ray tracing cores in this matchup. For compute-heavy tasks such as rendering, simulation, or machine learning inference, the Radeon Pro W6600X is the clear choice.

The CMP 30HX has a few narrow advantages in the recorded specifications. It offers higher memory bandwidth at 336.0 GB/s versus 256.0 GB/s, thanks to its 192-bit bus. It also has a larger physical footprint with recorded dimensions, which may matter for specific mounting scenarios. Its 125 W TDP is only slightly higher than the AMD card’s 120 W, so power consumption is not a differentiator. The CMP 30HX also has a lower transistor density, which could indicate simpler manufacturing requirements, but that is not a performance advantage.

In terms of use cases, the Radeon Pro W6600X suits professional graphics workloads that leverage Metal or DirectX 12 Ultimate features, including ray tracing. The CMP 30HX suits OpenCL or Vulkan compute tasks where its wider memory bus provides an edge, though its overall throughput is far lower. The database does not record any test where the CMP 30HX beats the Radeon Pro W6600X, so any practical win for the NVIDIA card would have to come from workload-specific behavior not captured in these benchmarks. For general performance, the verdict is unambiguous: the Radeon Pro W6600X dominates.
