AMD Radeon 860M vs NVIDIA CMP 70HX Comparison

Head-to-Head Benchmarks

The recorded benchmark data shows a clear overall performance advantage for the NVIDIA CMP 70HX across the two available compute workloads. In the Geekbench OpenCL test, the NVIDIA CMP 70HX scores 25,135 points against 22,759 points for the AMD Radeon 860M. That represents a 10.4% lead for the NVIDIA part in this compute-oriented workload. The gap widens considerably in the Vulkan API test, where the NVIDIA CMP 70HX reaches 35,817 points while the AMD Radeon 860M trails at 30,043 points, a 19.2% difference in favor of the NVIDIA product. Across the two tests, the NVIDIA CMP 70HX wins both head-to-head matchups, while the AMD Radeon 860M secures no victories.

The average benchmark score, which aggregates the recorded results, further illustrates the separation. The NVIDIA CMP 70HX holds an average score of 30,476, placing it in the 75th percentile of all GPUs in the database. The AMD Radeon 860M, by comparison, averages 26,401 points, which lands it in the 72nd percentile. This 4,075-point difference in average scores translates to a 15.4% overall gap, consistent with the individual test deltas.

When placed against their respective nearest rivals, the two products occupy very different competitive positions. The NVIDIA CMP 70HX is effectively tied with the NVIDIA Tesla M60, which averages 30,490 points, a delta of 0%. It also sits within 1.8% of the AMD Radeon RX 6700 (30,433), the AMD Radeon RX 6800 (30,095), and the NVIDIA GeForce RTX 3070 Ti (29,945). This suggests the CMP 70HX is operating in a performance tier populated by established discrete desktop GPUs. The AMD Radeon 860M, in contrast, finds its closest competition among lower-power mobile and workstation parts. It is within 1.1% of the NVIDIA GeForce MX550 (26,421), the NVIDIA GeForce RTX 5060 (26,331), the AMD Radeon RX 5700 XT 50th Anniversary (26,553), and the NVIDIA RTX A4000 (26,683). The fact that the 860M's nearest rivals are separated by less than 1.1% indicates that its performance is tightly clustered with these products, whereas the CMP 70HX's rivals are spread over a slightly wider range.

The Vulkan result is particularly telling. A 19.2% margin in that API suggests that the NVIDIA CMP 70HX scales better in workloads that leverage modern graphics and compute interfaces. The OpenCL result, while narrower, still confirms the NVIDIA part's superiority in a more traditional compute environment. For the AMD Radeon 860M, the gap between its OpenCL score (22,759) and its Vulkan score (30,043) is substantial, indicating that its performance is highly dependent on the API in use. The NVIDIA CMP 70HX shows a similar but smaller spread, from 25,135 in OpenCL to 35,817 in Vulkan.

Architecture Differences

The two GPUs come from fundamentally different design philosophies and process technologies. The NVIDIA CMP 70HX is built on the Ampere architecture using the GA104 chip, manufactured on Samsung's 8 nm process. The die contains 17,400 million transistors on a 392 mm² area, yielding a transistor density of 44.4 million transistors per square millimeter. The AMD Radeon 860M, meanwhile, uses the RDNA 3.5 architecture with the Krackan Point chip, manufactured on TSMC's 4 nm process. Its transistor count and die size are listed as unknown in the database, so a direct density comparison cannot be made from the recorded data.

The compute resources differ drastically. The NVIDIA CMP 70HX features 3,840 shading units, 120 texture mapping units, and 64 render output units. It also includes 30 ray tracing cores and 120 tensor cores. The AMD Radeon 860M has 512 shading units, 32 texture mapping units, and 16 render output units, along with 8 ray tracing cores. The AMD part has no tensor cores listed. These resource counts directly explain the performance gap: the NVIDIA part has 7.5 times the shading units, 3.75 times the texture units, and 4 times the render output units of the AMD part.

Clock speeds tell a different story. The AMD Radeon 860M has a base clock of 600 MHz and a boost clock of 3,000 MHz, which is exceptionally high for an integrated GPU. The NVIDIA CMP 70HX runs at a base clock of 1,365 MHz and a boost clock of 1,395 MHz, a much more conservative frequency range. Despite the AMD part's higher boost clock, the NVIDIA part's massive advantage in parallel hardware allows it to dominate in raw throughput. The pixel rate for the NVIDIA CMP 70HX is 89.28 GPixel/s versus 48.00 GPixel/s for the AMD part, and the texture rate is 167.4 GTexel/s versus 96.00 GTexel/s. In FP32 compute, the NVIDIA part delivers 10.71 TFLOPS, while the AMD part manages 3.072 TFLOPS, a 3.5x difference. Both GPUs support FP16 at a 1:1 ratio with their FP32 rates.

Memory architecture is another major divider. The NVIDIA CMP 70HX uses 8 GB of GDDR6X memory on a 256-bit bus, delivering 608.3 GB/s of bandwidth. The memory clock is listed at 1,188 MHz with 19 Gbps effective. The AMD Radeon 860M, being an integrated graphics processor, relies on system shared memory. Its memory size, type, bus width, and bandwidth are all listed as system dependent, meaning its performance will vary based on the host system's memory configuration. This distinction is critical: the NVIDIA part has dedicated, high-bandwidth memory, while the AMD part must contend for system memory bandwidth.

The process node difference is also notable. The AMD part's 4 nm TSMC process is significantly more advanced than the NVIDIA part's 8 nm Samsung process, which likely contributes to the AMD part's ability to reach 3,000 MHz. However, the NVIDIA part's much larger die and higher transistor count compensate for its older process node. The NVIDIA CMP 70HX is classified as an end-of-life product in the Mining GPUs generation, while the AMD Radeon 860M is listed as active, part of the Navi III IGP (Strix Point Mobile) generation, with a release date of February 28, 2025.

The Verdict

The data points to a straightforward conclusion: the NVIDIA CMP 70HX is the stronger performer in every recorded benchmark. Its 10.4% lead in OpenCL and 19.2% lead in Vulkan are decisive, and its average score of 30,476 places it in a higher overall percentile (75th) compared to the AMD Radeon 860M's 72nd percentile. For any workload that relies on compute performance, whether through OpenCL or Vulkan, the NVIDIA CMP 70HX is the better choice based on the recorded measurements.

However, the selection between these two products is not purely a matter of raw performance. The AMD Radeon 860M is an integrated graphics processor with a 15 W TDP, no power connectors, and an IGP slot width. It is designed for portable devices where power consumption and space are at a premium. Its performance is competitive with dedicated mobile GPUs like the NVIDIA GeForce MX550, which sits within 0.1% of its average score. The NVIDIA CMP 70HX, on the other hand, is a dual-slot discrete card with a 1x 12-pin power connector and a suggested power supply of 200 W. It has no display outputs, reflecting its mining-focused design. This means it cannot be used as a primary display adapter; it is purely a compute device.

The choice should be driven by the use case. For a system that needs integrated graphics with modest compute capability and minimal power draw, the AMD Radeon 860M is the appropriate part. Its performance is adequate for lightweight compute tasks and it requires no additional power infrastructure. For a system that needs maximum compute throughput and can accommodate a dual-slot card with dedicated power, the NVIDIA CMP 70HX is the superior option. Its memory bandwidth of 608.3 GB/s versus the AMD part's system-dependent bandwidth gives it a massive advantage in memory-intensive workloads.

There is no scenario in the recorded data where the AMD Radeon 860M outperforms the NVIDIA CMP 70HX. The NVIDIA part wins both head-to-head tests and holds a higher average score. The only reasons to prefer the AMD part are its lower power consumption, its integrated nature, and its active production status. The NVIDIA CMP 70HX is end-of-life, which may affect long-term availability. But strictly from the benchmark numbers, the NVIDIA CMP 70HX is the clear performance winner.
