NVIDIA CMP 70HX vs NVIDIA RTX A5000 Comparison

Where Each One Wins

The NVIDIA RTX A5000 and NVIDIA CMP 70HX occupy completely different corners of the GPU landscape, and the recorded data makes that split unambiguous. The RTX A5000 is a workstation-oriented Ampere part with a full complement of display outputs, while the CMP 70HX is a mining-focused card with no display outputs at all. In the benchmark suite covered by the database, the RTX A5000 wins every recorded comparison. It takes Geekbench OpenCL by a margin of 528.2% over the CMP 70HX, scoring 157,905 versus 25,135. In Geekbench Vulkan, the A5000 leads by 284.8%, with 137,828 against 35,817. These are not close contests; they represent a fundamental mismatch in compute capability.

The use-case split is therefore stark. The RTX A5000 is the clear choice for any workload that involves rendering, compute, or general graphics acceleration, as evidenced by its support for four DisplayPort 1.4a outputs and its DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 API coverage. The CMP 70HX, with no display outputs and a PCIe 1.0 x4 interface, is designed for a narrow set of tasks where raw memory bandwidth and compute throughput matter more than latency or graphics output. In the database's measurements, the A5000 delivers 768.0 GB/s of memory bandwidth from 24 GB of GDDR6, whereas the CMP 70HX provides 608.3 GB/s from 8 GB of GDDR6X. The A5000's 27.77 TFLOPS of FP32 performance dwarfs the CMP 70HX's 10.71 TFLOPS. For any user who needs to see the result of a computation, the A5000 is the only viable option here; the CMP 70HX cannot drive a display at all.

Architecture Differences

Both cards are built on the Ampere architecture and use Samsung's 8 nm process node, but they diverge sharply in silicon size and configuration. The RTX A5000 uses the GA102 chip, which packs 28,300 million transistors on a 628 mm² die, yielding a transistor density of 45.1M per mm². The CMP 70HX uses the smaller GA104 chip, with 17,400 million transistors on a 392 mm² die, for a density of 44.4M per mm². The A5000's larger die allows for substantially more execution resources: it has 8192 shading units, 256 texture mapping units, and 96 raster operation units. The CMP 70HX is cut down to 3840 shading units, 120 TMUs, and 64 ROPs. Ray tracing hardware follows the same pattern, with the A5000 featuring 64 RT cores and 256 tensor cores, while the CMP 70HX offers 30 RT cores and 120 tensor cores.

Clock behavior also differs. The A5000 runs at a base of 1170 MHz and boosts to 1695 MHz, while the CMP 70HX runs at a higher base of 1365 MHz but only boosts to 1395 MHz, a much narrower boost window. Memory technology is different as well: the A5000 uses GDDR6 at 16 Gbps effective across a 384-bit bus, while the CMP 70HX uses GDDR6X at 19 Gbps effective across a 256-bit bus. The A5000's wider bus gives it the bandwidth advantage despite slower per-pin speed. The CMP 70HX's PCIe 1.0 x4 interface is a legacy spec that severely limits host communication, but for mining workloads that stream data continuously, this is less of a bottleneck than it would be for interactive applications. The A5000, by contrast, uses PCIe 4.0 x16, which is the modern standard for workstation cards.

Power delivery differs too: the A5000 draws its power from a single 8-pin connector and has a listed TDP of 230 W, with a suggested PSU of 550 W. The CMP 70HX uses a single 12-pin connector, has no listed TDP, but suggests a 200 W PSU, indicating a much lower power envelope. Both cards are dual-slot designs with identical physical dimensions: 267 mm in length and 112 mm in height. The A5000 is marked end-of-life, as is the CMP 70HX, but the A5000 has a release date of April 11, 2021, while the CMP 70HX has no recorded release date.

Head-to-Head Benchmarks

The database records two head-to-head comparisons, and the RTX A5000 wins both by enormous margins. In Geekbench OpenCL, the A5000 scores 157,905 against the CMP 70HX's 25,135. That is a delta of 528.2%, meaning the A5000 delivers more than six times the OpenCL performance. This is the largest recorded gap between the two cards and reflects the A5000's much larger silicon, higher shading unit count, and wider memory bus. OpenCL is often used for compute-oriented tasks, and the A5000's 27.77 TFLOPS of FP32 throughput, combined with 768.0 GB/s of bandwidth, allows it to sustain heavy parallel workloads. The CMP 70HX, with 10.71 TFLOPS and 608.3 GB/s, is not in the same performance class.

In Geekbench Vulkan, the A5000 scores 137,828, while the CMP 70HX scores 35,817. The delta is 284.8%, a smaller relative gap than OpenCL but still a decisive victory. The A5000's 64 RT cores and 256 tensor cores provide substantial acceleration for Vulkan's graphics and compute paths, whereas the CMP 70HX's 30 RT cores and 120 tensor cores are a fraction of that capability. The A5000 also has a much higher pixel rate (162.7 GPixel/s versus 89.28 GPixel/s) and texture rate (433.9 GTexel/s versus 167.4 GTexel/s), which directly benefits any rendering workload.

It is worth noting how each card sits relative to its nearest rivals in the database. The A5000 has an average benchmark score of 33,622 and a percentile rank of 78 among all GPUs. Its closest rivals are the GeForce GTX 1060 5 GB (33,694 average score, 0.2% ahead), the Radeon RX 7700S (33,849, 0.7% ahead), the Radeon HD 7950 (33,951, 1% ahead), and the Radeon RX 480 (33,997, 1.1% ahead). These are tight margins, indicating that the A5000's average score is near a cluster of other GPUs. The CMP 70HX, by contrast, has an average score of 30,476 and a percentile rank of 75. Its nearest rivals are the Tesla M60 (30,490, 0% delta), the Radeon RX 6700 (30,433, 0.1% behind), the Radeon RX 6800 (30,095, 1.3% behind), and the GeForce RTX 3070 Ti (29,945, 1.8% behind). The CMP 70HX is slightly ahead of most of its nearest neighbors, but the entire cluster is well below the A5000's group.

The data shows that the CMP 70HX, despite its mining orientation, does not achieve the compute throughput of the workstation A5000. Its higher base clock and faster GDDR6X memory do not compensate for having half the shading units, a quarter of the memory capacity, and a much narrower memory bus. The A5000's two benchmark wins are not incremental; they are categorical. For any user evaluating these cards on the basis of recorded performance, the RTX A5000 is the superior GPU in every measured test. The CMP 70HX's only advantages are its lower suggested PSU (200 W versus 550 W) and its legacy PCIe 1.0 x4 interface, which is not a benefit for most applications. In the database's measurements, the RTX A5000 is the clear winner.
