AMD Radeon RX 7900M vs NVIDIA CMP 30HX Comparison

Head-to-Head Benchmarks

The benchmark data between the AMD Radeon RX 7900M and the NVIDIA CMP 30HX shows a decisive performance gap, with the Radeon taking both recorded wins. In Geekbench OpenCL, the RX 7900M scores 129,499 against the CMP 30HX’s 65,199, a 98.6% advantage. That is nearly double the compute output, and it reflects the fundamental difference in scale between a modern flagship mobile GPU and a mining-focused Turing card.

The Vulkan result is even more lopsided. The RX 7900M posts 158,760, while the CMP 30HX manages 62,484, giving AMD a 154.1% lead. Vulkan is often a better indicator of real-world gaming and compute efficiency on modern APIs, and the data here shows the Radeon is not just faster, it is in a completely different class. The CMP 30HX’s score is less than half of the RX 7900M’s, and no amount of driver optimization or workload tuning can bridge that chasm.

Looking at the average benchmark scores, the RX 7900M sits at 97,487, while the CMP 30HX averages 63,842. That is a 52.7% difference in overall throughput. The RX 7900M also ranks in the 94th percentile among all GPUs, whereas the CMP 30HX lands in the 89th percentile. The percentile gap is smaller than the raw score gap, which tells you that the CMP 30HX is still a competent card for its niche, but the Radeon is operating at a tier where only a small fraction of GPUs can compete.

The nearest rivals for the RX 7900M put its performance in context. The AMD Radeon Pro VII is only 0.4% behind, and the NVIDIA Quadro RTX 6000 is 4.3% ahead. The Radeon Instinct MI60 trails by 5.4%, and the RTX A4500 is 6.3% behind. So the RX 7900M sits in a tight pack of professional and workstation cards, which makes sense given its 16 GB memory and high compute throughput. The CMP 30HX, by contrast, is nearly tied with the AMD Radeon RX 9060 XT LP (0% delta), the RX 7600M (0.1% ahead), and the Radeon Pro Vega 56 (0.2% ahead). The Pro WX 9100 is 0.6% ahead. In other words, the CMP 30HX is a mid-range performer, while the RX 7900M is a high-end contender.

Architecture Differences

The architectural gap between these two is generational. The AMD Radeon RX 7900M uses the Navi 31 chip built on RDNA 3.0, codenamed Plum Bonito, and it is manufactured on a 5 nm process at TSMC. The NVIDIA CMP 30HX uses the TU116 chip based on the older Turing architecture, built on a 12 nm process, also at TSMC. The node difference is enormous: 5 nm versus 12 nm means the Radeon packs far more transistors into a similar physical footprint. The RX 7900M has 57,700 million transistors on a 529 mm² die, giving a density of 109.1 million transistors per square millimeter. The CMP 30HX has just 6,600 million transistors on a 284 mm² die, with a density of 23.2 million per square millimeter. That is a 4.7x density advantage for AMD, which directly translates into higher compute capacity.

The Radeon’s RDNA 3.0 architecture brings 4,608 shading units, 288 texture mapping units, and 192 render output units. It also includes 72 ray tracing cores, which the CMP 30HX lacks entirely. The NVIDIA card has 1,408 shading units, 88 TMUs, and 48 ROPs, with no ray tracing cores and no tensor cores. The RX 7900M also has no tensor cores, but its ray tracing hardware gives it a feature that the Turing mining card simply cannot offer. The CMP 30HX is a pure compute card stripped of display outputs, while the Radeon is a full-featured mobile GPU with portable device dependent outputs.

Clock speeds differ significantly as well. The RX 7900M runs at a base of 1825 MHz and boosts to 2090 MHz, while the CMP 30HX runs at 1530 MHz base and 1785 MHz boost. The Radeon’s higher clocks, combined with its massive shader count, produce a pixel rate of 401.3 GPixel/s and a texture rate of 601.9 GTexel/s. The CMP 30HX manages only 85.68 GPixel/s and 157.1 GTexel/s. FP32 throughput tells the story: the RX 7900M delivers 38.52 TFLOPS, while the CMP 30HX delivers 5.027 TFLOPS. That is a 7.7x difference in raw floating-point performance. FP16 is similarly lopsided: 77.05 TFLOPS versus 10.05 TFLOPS.

Where Each One Wins

The RX 7900M wins in every measurable category. It has superior compute, higher memory bandwidth, more VRAM, better API support, and a newer architecture. For gaming, the Radeon is the obvious choice, with DirectX 12 Ultimate (12_2) support, Vulkan 1.4, and ray tracing cores. The CMP 30HX only supports DirectX 12 (12_1) and has no ray tracing hardware. The Radeon’s 16 GB of GDDR6 memory on a 256-bit bus delivers 576.0 GB/s of bandwidth, while the CMP 30HX’s 6 GB on a 192-bit bus offers 336.0 GB/s. That is a 71.4% bandwidth advantage for AMD, which matters in texture-heavy workloads and high-resolution rendering.

The CMP 30HX does have one advantage: power draw. It is rated at 125 W TDP, while the RX 7900M is rated at 180 W. That is a 55 W difference, and for a mining card, lower power consumption can be a virtue. However, the CMP 30HX requires a 300 W suggested PSU and a single 8-pin power connector, while the Radeon is an integrated graphics package with no power connectors and no PSU recommendation. The CMP 30HX is also a dual-slot card with physical dimensions of 229 mm in length, 111 mm in height, and 35 mm in width. The Radeon is listed as IGP, meaning it is meant to be soldered onto a motherboard, which makes it entirely unsuitable for retrofitting into a desktop.

For compute workloads, the RX 7900M is the better pick for anything involving FP32 or FP16 math, ray tracing, or modern API features. The CMP 30HX is only relevant for cryptocurrency mining, where its lack of display outputs and stripped-down feature set are intentional. The data shows zero wins for the CMP 30HX in the head-to-head benchmarks, and its nearest rivals are all similarly positioned mid-range cards. If you are building a system for rendering, simulation, or AI inference, the Radeon is the clear winner. If you are running a mining rig, the CMP 30HX might still have a role, but the RX 7900M’s compute advantage would also make it more effective at solving the same algorithms, assuming you can integrate it.

Specification Differences

The two cards differ in almost every specification that matters. The process node is 5 nm for the Radeon versus 12 nm for the NVIDIA. Transistor count is 57,700 million versus 6,600 million. Die size is 529 mm² versus 284 mm². Base clock is 1825 MHz versus 1530 MHz, and boost clock is 2090 MHz versus 1785 MHz. Memory clock is 2250 MHz (18 Gbps effective) versus 1750 MHz (14 Gbps effective). Memory size is 16 GB versus 6 GB, bus width is 256-bit versus 192-bit, and bandwidth is 576.0 GB/s versus 336.0 GB/s.

Shading units: 4,608 versus 1,408. TMUs: 288 versus 88. ROPs: 192 versus 48. Ray tracing cores: 72 versus zero. Pixel rate: 401.3 GPixel/s versus 85.68 GPixel/s. Texture rate: 601.9 GTexel/s versus 157.1 GTexel/s. FP32: 38.52 TFLOPS versus 5.027 TFLOPS. FP16: 77.05 TFLOPS versus 10.05 TFLOPS. TDP: 180 W versus 125 W. Slot width: IGP versus dual-slot. Power connectors: none versus 1x 8-pin. Bus interface: PCIe 4.0 x16 versus PCIe 1.0 x4. Display outputs: portable device dependent versus none. DirectX support: 12 Ultimate (12_2) versus 12 (12_1). Vulkan support is identical at 1.4, and OpenGL is identical at 4.6.

Production status is Active for the Radeon and End-of-life for the NVIDIA. Release dates are 2023-10-18 for the RX 7900M and 2021-02-24 for the CMP 30HX. The CMP 30HX has a launch MSRP of 799 USD, which is worth noting as a historical data point, but the Radeon has no MSRP listed. The bus interface difference is particularly striking: the CMP 30HX uses PCIe 1.0 x4, which is a severe bottleneck for a modern GPU, while the Radeon uses PCIe 4.0 x16. That alone explains much of the CMP 30HX’s poor relative performance in bandwidth-sensitive tasks.

The Verdict

The data is unambiguous. The AMD Radeon RX 7900M is the superior product in every benchmark that was recorded, winning both head-to-head tests with margins of 98.6% and 154.1%. It has a newer architecture, a smaller process node, more memory, higher bandwidth, more shading units, and ray tracing support. The CMP 30HX is an end-of-life mining card with no display outputs, a narrow PCIe 1.0 x4 interface, and a fraction of the compute throughput.

If you are building a laptop or an integrated system that needs top-tier graphics performance, the RX 7900M is the only choice. Its 16 GB VRAM and 38.52 TFLOPS FP32 make it suitable for demanding games, content creation, and compute workloads. The CMP 30HX, with its 6 GB VRAM and 5.027 TFLOPS, is only relevant for a very specific mining use case, and even then, the Radeon’s raw compute advantage would make it more efficient at solving the same problems, provided you can handle its higher 180 W TDP.

The CMP 30HX has one practical edge: it is a standalone dual-slot card with a single 8-pin connector and a 300 W PSU recommendation, so it can be dropped into an existing desktop. The Radeon is an IGP, meaning it is not a drop-in part. But for anyone choosing between these two based on performance, the RX 7900M wins outright. The percentile rankings confirm it: 94th for the Radeon versus 89th for the NVIDIA. There is no scenario where the CMP 30HX outperforms the RX 7900M in the recorded benchmarks, and the architecture gap ensures that will remain true for any future workload. Pick the Radeon if you can integrate it; pick the CMP 30HX only if you need a low-power mining card with a specific form factor and no display requirements.
