Where Each One Wins

The benchmark data is unambiguous: the NVIDIA CMP 50HX wins both recorded tests. In Geekbench OpenCL, it posts 56,135 versus 41,263, a 36% advantage. In Geekbench Vulkan, it posts 47,445 versus 37,873, a 25.3% advantage. There are no recorded tests where the RTX A500 Mobile comes out ahead.

The CMP 50HX is designed for compute-oriented workloads. Its entire configuration, from the TU102 chip with 3,584 shading units to the 560.0 GB/s memory subsystem, is oriented toward sustained throughput. The RTX A500 Mobile, by contrast, is a low-power mobile part. Its 30 W TDP and 4 GB memory capacity make it a different class of device entirely.

The use-case split is therefore not about which card wins specific benchmarks, but about what each card is suited for. The CMP 50HX, with no display outputs, is a dedicated mining or compute card. The RTX A500 Mobile, with display outputs described as "Portable Device Dependent," is meant for mobile workstations where power draw and physical footprint are the primary constraints.

Architecture Differences

The two GPUs come from different architectural generations. The CMP 50HX is built on Turing, using the TU102 chip manufactured by TSMC on a 12 nm process. The RTX A500 Mobile is built on Ampere, using the GA107S chip manufactured by Samsung on an 8 nm process.

The transistor counts reflect the generational gap. The TU102 packs 18,600 million transistors across a 754 mm² die. The GA107S packs 8,700 million transistors across a 200 mm² die. Despite having fewer total transistors, the RTX A500 Mobile achieves a higher transistor density of 43.5M per mm², versus 24.7M per mm² for the CMP 50HX, thanks to the smaller 8 nm process node.

Both architectures support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. However, the compute feature sets differ. The CMP 50HX has 56 RT cores and 448 tensor cores. The RTX A500 Mobile has 16 RT cores and 64 tensor cores. The CMP 50HX also has significantly more shading units: 3,584 versus 2,048.

The FP16 throughput profiles differ substantially. The CMP 50HX delivers 22.15 TFLOPS FP16 using a 2:1 ratio relative to its 11.07 TFLOPS FP32. The RTX A500 Mobile delivers 6.296 TFLOPS FP16 at a 1:1 ratio with its 6.296 TFLOPS FP32. This means the CMP 50HX can double its throughput on FP16 workloads, while the RTX A500 Mobile cannot.

Specification Differences

The most obvious difference is physical form factor. The CMP 50HX is a dual-slot card measuring 267 mm in length, 116 mm in height, and 35 mm in width. The RTX A500 Mobile is an IGP (integrated graphics processor) with no recorded dimensions.

Memory capacity and bandwidth differ by a wide margin. The CMP 50HX has 10 GB of GDDR6 on a 320-bit bus with 560.0 GB/s bandwidth. The RTX A500 Mobile has 4 GB of GDDR6 on a 64-bit bus with 96.00 GB/s bandwidth. The memory clock also differs: the CMP 50HX runs at 1750 MHz (14 Gbps effective), while the RTX A500 Mobile runs at 1500 MHz (12 Gbps effective).

Clock speeds are closer than the rest of the specification sheet might suggest. The CMP 50HX has a base clock of 1350 MHz and a boost clock of 1545 MHz. The RTX A500 Mobile has a base clock of 832 MHz and a boost clock of 1537 MHz. The boost clocks are nearly identical, but the base clocks differ by more than 500 MHz.

The bus interface differs as well. The CMP 50HX uses PCIe 1.0 x4, which is an unusual limitation for a modern card. The RTX A500 Mobile uses PCIe 4.0 x8.

Pixel and texture rates reflect the raw compute differences. The CMP 50HX achieves 123.6 GPixel/s and 296.6 GTexel/s. The RTX A500 Mobile achieves 49.18 GPixel/s and 98.37 GTexel/s.

Power delivery is another major differentiator. The CMP 50HX has a 250 W TDP and requires two 8-pin connectors, with a suggested PSU of 600 W. The RTX A500 Mobile has a 30 W TDP and uses no external power connectors.

Release timing also differs. The CMP 50HX was released on 2021-06-23, while the RTX A500 Mobile was released on 2022-03-21. Both are marked as end-of-life in the database.

Head-to-Head Benchmarks

The Geekbench OpenCL test shows the largest gap between the two cards. The CMP 50HX scores 56,135, while the RTX A500 Mobile scores 41,263. The 36% delta is the biggest recorded win for either card in the head-to-head comparison. This result is consistent with the CMP 50HX having nearly twice the shading units, more than five times the memory bandwidth, and a much larger die.

The Geekbench Vulkan test shows a smaller but still decisive gap. The CMP 50HX scores 47,445, and the RTX A500 Mobile scores 37,873. The 25.3% delta indicates that the Vulkan workload does not scale as strongly with the CMP 50HX's hardware advantages, but the CMP 50HX still maintains a comfortable lead.

The average benchmark scores reinforce the head-to-head results. The CMP 50HX averages 51,790 across all recorded tests, placing it at the 86th percentile of all GPUs in the database. The RTX A500 Mobile averages 39,568, placing it at the 82nd percentile.

The nearest rival data provides additional context. The CMP 50HX's closest competitor is the AMD Radeon RX 6900 XT, which averages 50,951, a 1.6% delta. The RTX A500 Mobile's closest competitor is the AMD Radeon Pro 575, which averages 39,555, a 0% delta. This suggests the CMP 50HX is competing at a much higher absolute performance tier, while the RTX A500 Mobile sits in a lower tier.

The Verdict

The data supports a clear conclusion: the NVIDIA CMP 50HX is the faster GPU in every recorded benchmark. It wins Geekbench OpenCL by 36% and Geekbench Vulkan by 25.3%. Its average benchmark score of 51,790 is 31% higher than the RTX A500 Mobile's 39,568.

The CMP 50HX is the right choice for workloads that demand raw compute throughput. Its 3,584 shading units, 56 RT cores, 448 tensor cores, and 560.0 GB/s of memory bandwidth give it a commanding lead in both OpenCL and Vulkan tests. The 36% OpenCL delta and 25.3% Vulkan delta are substantial margins that would be difficult to overcome in any compute-heavy scenario.

The RTX A500 Mobile is the right choice for a different set of constraints. Its 30 W TDP, IGP form factor, and lack of external power connectors make it suitable for mobile platforms where power and space are the limiting factors. Its performance, while lower, is still respectable: the 82nd percentile ranking places it above the majority of GPUs in the database.

For users who can accommodate a 250 W dual-slot card with two 8-pin power connectors, the CMP 50HX is the clear performance winner. For users who need a low-power mobile solution with no external power requirements, the RTX A500 Mobile is the only viable option of the two. The choice depends entirely on the physical and power constraints of the target system, not on benchmark performance, where the CMP 50HX is dominant.
