GPU Comparison

Head-to-Head Benchmarks

The recorded benchmark data shows a decisive performance gap between the AMD Radeon PRO W7700 and the NVIDIA CMP 30HX across both tested workloads. In Geekbench OpenCL, the AMD card scores 108,245 points against 65,199 for the NVIDIA card, a 66% advantage. The gap widens substantially in Geekbench Vulkan, where the AMD card posts 129,706 points versus 62,484 for the NVIDIA card, a 107.6% lead. These are not marginal differences; the AMD part more than doubles the NVIDIA part in one test and leads by two-thirds in the other.

The Vulkan result is particularly telling. A 107.6% delta means the AMD card delivers over twice the compute output in that API, which reflects both architectural efficiency and raw execution resources. The OpenCL margin, while smaller in relative terms, still represents a commanding win. Across the two recorded benchmarks, the AMD Radeon PRO W7700 wins both, giving it a 2-0 record in direct comparison. The NVIDIA CMP 30HX has no benchmark wins in this dataset.

Context from the database's nearest-rival rankings reinforces the scale of this disparity. The AMD Radeon PRO W7700 sits at the 95th percentile among all GPUs, with an average benchmark score of 118,976. Its nearest rivals include the NVIDIA GB10 at 117,393 (1.3% behind), the NVIDIA RTX 4000 SFF Ada Generation at 117,088 (1.6% behind), the NVIDIA Tesla V100 SXM2 16 GB at 114,395 (4% behind), and the NVIDIA RTX A5500 Mobile at 113,944 (4.4% behind). The AMD card leads every one of these by a small but consistent margin.

The NVIDIA CMP 30HX, by contrast, sits at the 89th percentile with an average score of 63,842. Its nearest rivals are grouped tightly around it: the AMD Radeon RX 9060 XT LP at 63,830 (0% delta), the AMD Radeon RX 7600M at 63,775 (0.1% behind), the AMD Radeon Pro Vega 56 at 63,693 (0.2% behind), and the AMD Radeon Pro WX 9100 at 64,212 (0.6% ahead). The CMP 30HX effectively trades blows with these cards, none of which come close to the Radeon PRO W7700's output.

The Verdict

The data points to a clear conclusion: the AMD Radeon PRO W7700 is the superior performer in every measured benchmark. For workloads that rely on OpenCL or Vulkan compute, the AMD card delivers 66% to 107.6% higher scores. Anyone choosing between these two for compute-heavy tasks should select the AMD Radeon PRO W7700 without hesitation, as the NVIDIA CMP 30HX offers no performance advantage in any recorded test.

However, the choice is not purely computational. The NVIDIA CMP 30HX has no display outputs, making it unsuitable for any workstation role that requires driving a monitor. The AMD Radeon PRO W7700 provides 4x DisplayPort 2.1 outputs, enabling direct display connectivity. The NVIDIA card is classified under "Mining GPUs" and carries an end-of-life production status, while the AMD card belongs to the Radeon Pro Navi generation and remains a current professional product.

The NVIDIA CMP 30HX does win on power efficiency in absolute terms, with a 125 W TDP against 190 W for the AMD card. Its suggested PSU is 300 W versus 450 W. But these figures do not compensate for the massive performance deficit. The AMD card delivers roughly 3.3 times the average benchmark score while consuming only 1.5 times the power, meaning its performance-per-watt is substantially higher. The recorded data offers no scenario where the NVIDIA card is the better pick, except possibly where absolute power draw is the sole constraint and performance is irrelevant.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The AMD Radeon PRO W7700 uses the Navi 32 chip built on RDNA 3.0 architecture, with the codename Wheat Nas. It is fabricated on a 5 nm process at TSMC, housing 28,100 million transistors on a 346 mm² die. The transistor density works out to 81.2 million transistors per square millimeter.

The NVIDIA CMP 30HX uses the TU116 chip built on Turing architecture. It is fabricated on a 12 nm process, also at TSMC, with 6,600 million transistors on a 284 mm² die. The transistor density is 23.2 million per square millimeter. The process node difference is stark: 5 nm versus 12 nm, which explains why the AMD chip packs over four times as many transistors into only 22% more die area.

The AMD card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The API ceiling differs slightly, with the AMD part meeting the higher feature tier. The AMD card also includes 48 ray tracing cores, while the NVIDIA card has none listed. Neither card lists tensor cores, so those are not differentiating factors here.

The AMD card uses RDNA 3.0, which is designed for modern workstation and compute workloads, while the NVIDIA card uses Turing, which is an older architecture originally aimed at gaming and later repurposed for mining. The production status confirms this: the NVIDIA card is end-of-life, while the AMD card has no such status listed.

Specification Differences

The specifications diverge sharply across nearly every category. The AMD Radeon PRO W7700 has 3,072 shading units, 192 texture mapping units, and 96 raster operation units, plus 48 ray tracing cores. The NVIDIA CMP 30HX has 1,408 shading units, 88 TMUs, and 48 ROPs, with no ray tracing cores. The AMD card thus has 2.2 times the shading units, 2.2 times the TMUs, and 2 times the ROPs.

Clock speeds also favor the AMD card. Its base clock is 1900 MHz and boost clock is 2600 MHz, versus 1530 MHz base and 1785 MHz boost for the NVIDIA card. Memory clocks differ as well: the AMD card runs at 2250 MHz with 18 Gbps effective, while the NVIDIA card runs at 1750 MHz with 14 Gbps effective.

Memory capacity and bandwidth show a wide gap. The AMD card has 16 GB of GDDR6 on a 256-bit bus, yielding 576.0 GB/s bandwidth. The NVIDIA card has 6 GB of GDDR6 on a 192-bit bus, yielding 336.0 GB/s. The AMD card offers 2.7 times the capacity and 1.7 times the bandwidth.

Pixel and texture rates follow the same pattern. The AMD card achieves 249.6 GPixel/s and 499.2 GTexel/s, while the NVIDIA card manages 85.68 GPixel/s and 157.1 GTexel/s. Floating-point performance: the AMD card delivers 31.95 TFLOPS FP32 and 63.90 TFLOPS FP16 (2:1), versus 5.027 TFLOPS FP32 and 10.05 TFLOPS FP16 for the NVIDIA card. The AMD part is 6.4 times faster in FP32 and 6.4 times faster in FP16.

Physical and interface differences matter too. The AMD card uses PCIe 4.0 x16, while the NVIDIA card uses PCIe 1.0 x4. That older interface severely limits data transfer for any workload that moves data between CPU and GPU. The AMD card is 241 mm long and 111 mm tall; the NVIDIA card is 229 mm long, 111 mm tall, and 35 mm wide. Both are dual-slot and use a single 8-pin power connector. The AMD card has a 190 W TDP and 450 W suggested PSU; the NVIDIA card has a 125 W TDP and 300 W suggested PSU. The AMD card offers 4x DisplayPort 2.1 outputs; the NVIDIA card has no outputs. Release dates differ by roughly 2.5 years: the AMD card launched November 12, 2023, while the NVIDIA card launched February 24, 2021. The AMD card's predecessor is listed as Radeon Pro Vega; the NVIDIA card has no predecessor listed. The AMD card's launch MSRP is 999 USD; the NVIDIA card's launch MSRP is 799 USD.

Where Each One Wins

The AMD Radeon PRO W7700 wins in every recorded benchmark, so the use-case split is defined by factors beyond raw compute scores. For any workload that involves OpenCL or Vulkan compute, rendering, simulation, or GPU-accelerated analysis, the AMD card is the clear choice. Its 2-0 benchmark record, 66% OpenCL lead, and 107.6% Vulkan lead leave no ambiguity. The card's 16 GB memory capacity and 576.0 GB/s bandwidth also support larger datasets and more complex scenes than the 6 GB and 336.0 GB/s of the NVIDIA card.

The AMD card also wins for any role that requires display output. Its 4x DisplayPort 2.1 connections allow direct monitor attachment, while the NVIDIA card has no outputs at all. The AMD card's PCIe 4.0 x16 interface provides far greater host bandwidth than the NVIDIA card's PCIe 1.0 x4 interface, which matters for workloads that stream data from CPU memory. The AMD card's ray tracing cores add another capability the NVIDIA card simply lacks.

The NVIDIA CMP 30HX has only one plausible niche in the data: scenarios where absolute power draw must stay low. Its 125 W TDP and 300 W suggested PSU are lower than the AMD card's 190 W and 450 W. But even here, the performance-per-watt calculation favors the AMD card, since it produces roughly 86% more average benchmark score per watt of TDP. The NVIDIA card's end-of-life status and mining-focused classification further limit its appeal. Its launch MSRP was 799 USD, but with no display outputs, no ray tracing, and less than a third of the average benchmark score, it cannot compete for professional workstation duties. The recorded data supports only one conclusion: the AMD Radeon PRO W7700 is the superior product across every measured dimension, and the NVIDIA CMP 30HX should be chosen only if power draw is the absolute limiting factor and performance is irrelevant.
