Architecture Differences

The NVIDIA CMP 40HX is built on the Turing architecture using the TU106 chip, manufactured on a 12 nm process at TSMC. The AMD Radeon RX 7600M uses the RDNA 3.0 architecture with the Navi 33 chip, built on a 6 nm process, also at TSMC. This process difference is substantial: the CMP 40HX has 10,800 million transistors spread across a 445 mm² die, resulting in a transistor density of 24.3 million per mm². The RX 7600M packs 13,300 million transistors into a much smaller 204 mm² die, yielding a density of 65.2 million per mm². The newer process node allows AMD to pack more transistors into less space, which contributes to its higher clock speeds.

The CMP 40HX has a base clock of 1470 MHz and a boost clock of 1650 MHz. The RX 7600M has a base clock of 1500 MHz and a much higher boost clock of 2410 MHz, with a game clock rated at 2070 MHz. This clockspeed advantage is significant for the AMD part.

In terms of compute units, the NVIDIA card has 2304 shading units, 144 texture mapping units, and 64 render output units. It also includes 36 ray tracing cores and 288 tensor cores, which are specialized for ray tracing and AI workloads. The AMD card has 1792 shading units, 112 texture mapping units, and 64 render output units. It has 28 ray tracing cores but no tensor cores listed. This means NVIDIA has a higher raw count of shaders and dedicated tensor hardware, while AMD relies on its higher clockspeeds to compensate.

The CMP 40HX has no display outputs, as it is a mining-focused card. The RX 7600M has display outputs that are described as "Portable Device Dependent," meaning they vary by the laptop implementation. The NVIDIA card is a dual-slot, 229 mm long PCIe card, while the AMD GPU is an IGP with no dimensions listed, designed for mobile integration.

Memory configurations also differ. Both have 8 GB of GDDR6, but the CMP 40HX uses a 256-bit bus with 448.0 GB/s bandwidth, while the RX 7600M uses a 128-bit bus with 256.0 GB/s bandwidth. The NVIDIA card has a significant bandwidth advantage, though the AMD card has a higher effective memory speed of 16 Gbps versus 14 Gbps.

Head-to-Head Benchmarks

The database records a single head-to-head benchmark between these two GPUs: Geekbench OpenCL. In this test, the NVIDIA CMP 40HX scores 93,395, while the AMD Radeon RX 7600M scores 63,775. The delta is 46.4% in favor of NVIDIA. This is a decisive win for the CMP 40HX.

To contextualize this result, look at the nearest rivals for each card. The CMP 40HX's average benchmark score of 85,637 places it just 1.7% behind the AMD Radeon PRO W7600 (87,108), 2.1% behind the NVIDIA Quadro GP100 (87,445), and 4.4% ahead of the AMD Radeon PRO W6600 (81,995). The RX 7600M's average score of 63,775 is essentially tied with the AMD Radeon RX 9060 XT LP (63,830, a 0.1% difference) and the NVIDIA CMP 30HX (63,842, a 0.1% difference). It is 0.1% ahead of the AMD Radeon Pro Vega 56 (63,693).

The gap between the two cards in raw compute is substantial. The CMP 40HX delivers 7.603 TFLOPS of FP32 performance, while the RX 7600M delivers 17.27 TFLOPS. This is a surprising inversion: the AMD card has more than double the theoretical FP32 throughput, yet it scores far lower in the OpenCL benchmark. This discrepancy suggests that the RX 7600M's mobile implementation, with its lower power envelope and narrower memory bus, may be limiting its real-world performance. The CMP 40HX's higher memory bandwidth (448.0 GB/s vs 256.0 GB/s) likely plays a major role in its OpenCL advantage.

The pixel rate and texture rate tell a different story. The RX 7600M has a pixel rate of 154.2 GPixel/s and a texture rate of 269.9 GTexel/s, both higher than the CMP 40HX's 105.6 GPixel/s and 237.6 GTexel/s. This indicates that the AMD card is more capable in fill-rate-limited scenarios, even though it loses the compute benchmark.

Where Each One Wins

The NVIDIA CMP 40HX wins decisively in the only recorded benchmark, the Geekbench OpenCL test, with a 46.4% lead. Its strengths lie in its memory subsystem: the 256-bit bus and 448.0 GB/s bandwidth are far superior to the RX 7600M's 128-bit bus and 256.0 GB/s. For workloads that are memory-bandwidth sensitive, such as certain compute tasks, the CMP 40HX has a clear edge. It also has more shading units, more ray tracing cores, and the addition of 288 tensor cores, which the AMD card lacks entirely. The CMP 40HX is a desktop card with a dedicated 8-pin power connector and a 185 W TDP, allowing it to sustain higher power draw for consistent performance.

The AMD Radeon RX 7600M wins on architectural efficiency and theoretical compute. Its 6 nm process allows for a much smaller die with more transistors, and its boost clock of 2410 MHz is significantly higher than the CMP 40HX's 1650 MHz. The RX 7600M has more than double the FP32 throughput (17.27 TFLOPS vs 7.603 TFLOPS) and more than double the FP16 throughput (34.55 TFLOPS vs 15.21 TFLOPS). It also has higher pixel and texture fill rates. As an IGP with a 90 W TDP, it is designed for mobile devices, meaning it can be integrated into laptops without a separate power connector. Its PCIe 4.0 x16 interface is vastly superior to the CMP 40HX's PCIe 1.0 x4, which is a legacy bottleneck.

For gaming or general graphics workloads, the RX 7600M's higher clockspeeds and fill rates likely make it more responsive, though the database does not record gaming benchmarks. For compute-heavy tasks that resemble the OpenCL test, the CMP 40HX is the stronger choice. The RX 7600M is also an active product with a 2023 release date, while the CMP 40HX is end-of-life and was released in 2021 specifically for mining, as indicated by its lack of display outputs.

The Verdict

The data is unambiguous in the recorded head-to-head: the NVIDIA CMP 40HX outperforms the AMD Radeon RX 7600M by 46.4% in Geekbench OpenCL. If your primary concern is raw compute performance as measured by this benchmark, the CMP 40HX is the better pick. Its higher memory bandwidth, larger shading unit count, and tensor core support give it a substantial practical advantage in this test. However, the CMP 40HX is a mining-specific card with no display outputs, so it cannot be used for any visual output. It is also end-of-life, with a launch MSRP of 699 USD, and requires a desktop slot, an 8-pin connector, and a 450 W power supply.

The AMD Radeon RX 7600M is a different class of product. It is a mobile IGP with no power connector requirements and a 90 W TDP, making it suitable for laptops. Its theoretical compute is much higher, and its newer architecture and process node suggest better efficiency. For users who need a GPU for a portable device and can tolerate lower OpenCL scores, the RX 7600M is the sensible choice. For users who need maximum compute performance in a desktop and do not require display outputs, the CMP 40HX delivers the better benchmark result despite its age and mining focus.

The percentile rankings support this split: the CMP 40HX is in the 93rd percentile of all GPUs, while the RX 7600M is in the 89th. Both are capable, but the CMP 40HX is the stronger performer in the database's recorded metrics. The RX 7600M's advantages are architectural and theoretical, not reflected in the single benchmark score. Ultimately, the choice depends on the use case: a desktop compute workload favors NVIDIA, while a mobile graphics workload favors AMD.
