NVIDIA CMP 30HX vs NVIDIA RTX A4500 Comparison

Where Each One Wins

The recorded data splits this pairing cleanly: the NVIDIA RTX A4500 wins every available benchmark comparison, taking both head-to-head tests. The NVIDIA CMP 30HX does not record a single win in any shared test. That makes the use-case split straightforward: the RTX A4500 is the compute and graphics performer, while the CMP 30HX has no display outputs and was built for a different purpose entirely.

In OpenCL compute workloads, the RTX A4500 posts a score of 141,837 against 65,199 for the CMP 30HX. That is a 117.5% advantage, meaning the A4500 delivers more than double the compute throughput in this test. For Vulkan graphics and general compute, the A4500 scores 129,980 versus 62,484, a 108% lead. The CMP 30HX cannot output video at all, so any task requiring a display connection falls exclusively to the A4500.

The average benchmark score in the database reinforces the split: the RTX A4500 averages 91,671 across all recorded tests, while the CMP 30HX averages 63,842. The A4500 sits at the 93rd percentile among all GPUs in the database; the CMP 30HX sits at the 89th. Neither is a slouch, but the A4500 is clearly the higher-tier part in raw performance terms.

For professional workloads such as 3D rendering, simulation, or GPU-accelerated computation, the A4500 is the only realistic choice from these two. The CMP 30HX, with no display outputs and a mining-oriented design, offers no path to interactive graphics or standard workstation use. If a system must drive monitors and run compute, the A4500 wins on both counts.

Architecture Differences

The two cards come from different architectures and different fabs. The RTX A4500 uses the GA102 chip on the Ampere architecture, built on an 8 nm process at Samsung. The CMP 30HX uses the TU116 chip on the Turing architecture, built on a 12 nm process at TSMC. The transistor counts differ wildly: the A4500 packs 28,300 million transistors on a 628 mm² die, while the CMP 30HX has 6,600 million transistors on a 284 mm² die. Transistor density follows suit, with the A4500 at 45.1 million per mm² versus 23.2 million per mm² for the CMP 30HX.

The A4500 is a fully featured workstation GPU. It has 7,168 shading units, 224 texture mapping units, and 96 raster output units. It includes 56 ray tracing cores and 224 tensor cores, making it suitable for ray-traced rendering and AI-accelerated workloads. The CMP 30HX has far fewer resources: 1,408 shading units, 88 TMUs, and 48 ROPs. It has no ray tracing cores and no tensor cores at all, which removes it from any task involving hardware-accelerated ray tracing or tensor-based machine learning inference.

Memory configurations also separate the two. The A4500 carries 20 GB of GDDR6 on a 320 bit bus, yielding 640.0 GB/s of bandwidth. The CMP 30HX has 6 GB of GDDR6 on a 192 bit bus, producing 336.0 GB/s. Clock speeds tell a different story: the CMP 30HX runs higher at 1530 MHz base and 1785 MHz boost, while the A4500 runs at 1050 MHz base and 1650 MHz boost. Memory clocks also favor the CMP 30HX on a raw frequency basis (1750 MHz versus 2000 MHz, but the A4500's memory operates at 16 Gbps effective versus 14 Gbps effective for the CMP 30HX). The A4500 compensates with far more execution units and a wider memory bus.

The interface and power profiles differ too. The A4500 uses PCIe 4.0 x16, while the CMP 30HX uses PCIe 1.0 x4, a severe bottleneck for data transfer. The A4500 has a 200 W TDP and suggests a 550 W power supply; the CMP 30HX has a 125 W TDP and suggests a 300 W unit. The A4500 outputs 4x DisplayPort 1.4a, while the CMP 30HX has no outputs. For API support, the A4500 reaches DirectX 12 Ultimate (12_2), while the CMP 30HX tops out at DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

Head-to-Head Benchmarks

The database records two shared benchmark tests: Geekbench OpenCL and Geekbench Vulkan. The RTX A4500 wins both, and by substantial margins.

In Geekbench OpenCL, the A4500 scores 141,837 against 65,199 for the CMP 30HX. That is a delta of 117.5%. This test exercises raw compute throughput across the GPU's execution units, and the A4500's 7,168 shading units plus 224 tensor cores and 56 RT cores provide a massive parallel advantage over the CMP 30HX's 1,408 shading units with no RT or tensor hardware. The A4500 also has more than double the memory bandwidth, which helps feed those units.

In Geekbench Vulkan, the A4500 scores 129,980 versus 62,484, a 108% delta. Vulkan workloads mix graphics and compute, and the A4500's higher ROP count (96 versus 48) and pixel rate (158.4 GPixel/s versus 85.68 GPixel/s) contribute to the win. The CMP 30HX has a higher boost clock (1785 MHz versus 1650 MHz), but that cannot overcome the A4500's 5x advantage in shading units and its wider memory bus.

The CMP 30HX does win on one metric: efficiency of the compute per watt is not directly recorded, but its TDP of 125 W is lower than the A4500's 200 W. However, the performance per watt is not in the data, and the A4500's absolute scores are far higher. The CMP 30HX also has a higher FP16 rate relative to FP32 (10.05 TFLOPS at 2:1 ratio versus 23.65 TFLOPS at 1:1 for the A4500), but the A4500's FP16 absolute throughput is still more than double.

The Verdict

The data makes the choice unambiguous for any general-purpose computing or graphics task: the NVIDIA RTX A4500 is the superior card. It wins both head-to-head benchmarks by margins exceeding 100%, offers 20 GB of memory versus 6 GB, includes ray tracing and tensor cores, and provides four display outputs. Its average benchmark score of 91,671 places it well above the CMP 30HX's 63,842, and its 93rd percentile ranking beats the CMP 30HX's 89th.

The CMP 30HX has no path to a workstation role. It lacks display outputs, has no RT or tensor hardware, uses a PCIe 1.0 x4 interface that severely limits data transfer, and its 6 GB memory capacity is restrictive for modern workloads. Its only advantages are a lower TDP of 125 W and a smaller physical footprint, but those do not translate into any benchmark win.

The RTX A4500 is the pick for professionals who need to render, compute, or drive multiple displays. The CMP 30HX should only be considered for a niche mining application where display output and ray tracing are irrelevant, and even then its 89th percentile performance places it behind the A4500 in every measured test. The verdict is not close: the A4500 wins on all recorded performance metrics, and the CMP 30HX's sole purpose is outside the scope of standard GPU workloads.
