NVIDIA CMP 70HX vs NVIDIA RTX A2000 12 GB Comparison

Where Each One Wins

The recorded data splits these two Ampere-generation cards into sharply different roles. The NVIDIA RTX A2000 12 GB dominates in the only shared compute test, Geekbench OpenCL, by a massive 166.6% margin. That single result defines its profile: it is a workstation-oriented card that translates its feature set into strong general-purpose compute performance. The A2000 also holds a higher average benchmark score of 34154 against the CMP 70HX’s 30476, a difference of roughly 12% in overall database standing.

The NVIDIA CMP 70HX, by contrast, has no wins in the head-to-head data. Its strengths, such as they exist, are not captured in the shared benchmark because it was never tested in the same OpenCL workload with comparable success. Instead, the database shows it has its own separate benchmarks: a Geekbench Vulkan score of 35817, which is higher than its OpenCL result of 25135. That gap suggests the card is more responsive under Vulkan, but it does not change the fact that in the one direct comparison available, the A2000 is decisively ahead.

The use-case split is therefore clear from the numbers. The A2000 is built for compute workloads that leverage OpenCL, the kind of tasks common in professional 3D, rendering, and CAD environments. The CMP 70HX, with its mining-oriented generation label and lack of display outputs, is not designed for interactive graphics or general compute in the same way. Its performance profile, while respectable in Vulkan, is not competitive with the A2000 in the compute arena that the database measures head-to-head.

Architecture Differences

Both cards share the Ampere architecture and are fabricated on the same 8 nm process at Samsung, but they diverge in nearly every other physical and functional detail. The A2000 uses the GA106 chip, a smaller die at 276 mm² with 12,000 million transistors. The CMP 70HX uses the GA104 chip, which is larger at 392 mm² and packs 17,400 million transistors. Transistor density is close: 43.5M per mm² for the A2000 versus 44.4M per mm² for the CMP 70HX, so the real difference is raw scale, not packing efficiency.

Memory is another major separation. The A2000 has 12 GB of GDDR6 on a 192-bit bus, delivering 288.0 GB/s of bandwidth. The CMP 70HX has 8 GB of GDDR6X on a 256-bit bus, delivering 608.3 GB/s, more than double the bandwidth. The CMP 70HX also runs its memory at a higher effective speed of 19 Gbps, while the A2000 runs at 12 Gbps effective. The CMP 70HX’s memory clocks are lower at 1188 MHz base, but the effective transfer rate is what matters for bandwidth, and it is clearly superior.

Compute resources also favor the CMP 70HX on paper. It has 3840 shading units, 120 TMUs, 64 ROPs, 30 RT cores, and 120 tensor cores. The A2000 has 3328 shading units, 104 TMUs, 48 ROPs, 26 RT cores, and 104 tensor cores. The CMP 70HX also has higher clock speeds: a base of 1365 MHz and a boost of 1395 MHz, versus 562 MHz base and 1200 MHz boost for the A2000. This results in higher theoretical rates for the CMP 70HX: 89.28 GPixel/s pixel rate, 167.4 GTexel/s texture rate, and 10.71 TFLOPS FP32. The A2000 manages 57.60 GPixel/s, 124.8 GTexel/s, and 7.987 TFLOPS FP32.

Yet the A2000 wins the real-world compute test. That is the central contradiction in the data, and it points to differences beyond raw spec sheets. The A2000 has a PCIe 4.0 x16 interface, while the CMP 70HX uses PCIe 1.0 x4, a severe bottleneck for any workload that transfers data back and forth. The A2000 also features display outputs, 4x mini-DisplayPort 1.4a, while the CMP 70HX has none. The CMP 70HX’s generation label, "Mining GPUs," and its single 12-pin power connector, versus the A2000’s connectorless design, further confirm that it was specialized for a narrow task, not general compute.

Head-to-Head Benchmarks

The only direct comparison in the database is Geekbench OpenCL, and the result is lopsided. The A2000 scores 66998, while the CMP 70HX scores 25135. That is a delta of 166.6% in favor of the A2000, meaning the A2000 is more than two and a half times faster in this workload. No other shared benchmark exists, so the head-to-head picture is incomplete but also unambiguous: in the one arena where both cards were measured, the A2000 is the clear winner.

Why such a gap despite the CMP 70HX’s higher theoretical FP32 and bandwidth? The likely factors visible in the data are the PCIe interface and the driver or firmware optimizations. The CMP 70HX’s PCIe 1.0 x4 connection is a severe constraint for OpenCL workloads that rely on host-device communication. The A2000’s PCIe 4.0 x16 connection is sixteen times the bandwidth in each direction, and that can dominate in compute tasks that are not purely shader-bound. Also, the A2000 is a workstation product with a mature driver stack aimed at professional applications, whereas the CMP 70HX is a mining card with no display path and likely no compute-optimized driver support.

The separate Vulkan result for the CMP 70HX, 35817, is higher than its own OpenCL score but still far below the A2000’s OpenCL number. That suggests the CMP 70HX’s architecture can perform better under a different API, but it is not a direct comparison because the A2000 was not tested in Vulkan. The database only records wins for the A2000: 1 win, 0 for the CMP 70HX.

The Verdict

From the recorded data, the NVIDIA RTX A2000 12 GB is the superior card for any compute-focused use case. Its Geekbench OpenCL score is 166.6% higher than the CMP 70HX’s, its average benchmark score is about 12% higher, and it sits in the 79th percentile of all GPUs, compared to the CMP 70HX’s 75th percentile. The A2000 also has more memory, 12 GB versus 8 GB, and a modern PCIe 4.0 x16 interface, plus display outputs for professional work. Its nearest rivals are the NVIDIA RTX A1000, TITAN V, and AMD Radeon RX 480 and RX 560 XT, all within 0.6% of its average score, which shows it is a well-balanced mid-range workstation card.

The CMP 70HX, meanwhile, sits near the NVIDIA Tesla M60, AMD Radeon RX 6700, RX 6800, and GeForce RTX 3070 Ti in average score, all within 1.8%. Its Vulkan score is respectable, but its lack of display outputs, PCIe 1.0 x4 interface, and mining-specific design make it unsuitable for general use. The data does not support any scenario where the CMP 70HX is the better choice for a workstation buyer, a gamer, or a compute professional. It was built for a specific mining workload, and that is where its higher memory bandwidth might have mattered, but the database does not include any mining benchmark to confirm that.

Who should pick which? If the task involves OpenCL compute, professional 3D, rendering, or any interactive graphics, the A2000 is the only defensible option. If the task is purely Vulkan-based, the CMP 70HX’s score of 35817 is higher than its own OpenCL result, but there is no A2000 Vulkan score to compare against, so no conclusion can be drawn. The prudent reading is that the A2000 is the safer, more capable card across the board based on the available measurements.
