NVIDIA CMP 70HX vs NVIDIA Quadro GV100 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive victory for the NVIDIA Quadro GV100 across the two shared benchmark tests. In Geekbench OpenCL, the GV100 scores 150,004, which is 496.8% higher than the CMP 70HX's 25,135. This is not a marginal lead; it is a near-sixfold advantage in raw compute throughput as measured by this workload. The gap narrows somewhat in Geekbench Vulkan, but the GV100 still delivers a 289.6% advantage, posting 139,526 against the CMP 70HX's 35,817.

These results place the two cards in different performance strata. The Quadro GV100's average benchmark score of 35,520 puts it at the 80th percentile among all GPUs in the database. Its nearest rival, the NVIDIA GeForce RTX 5070 Ti Mobile, scores 35,435, a delta of just 0.2%, meaning the GV100 sits in a tightly contested performance cluster at the top of the distribution. The CMP 70HX, by contrast, has an average benchmark score of 30,476, placing it at the 75th percentile. Its closest competitor, the NVIDIA Tesla M60, scores 30,490, a delta of 0.0%, making the CMP 70HX effectively tied with that card in aggregate performance.

The magnitude of the head-to-head deltas is striking given how close the two cards are in their percentile rankings. The GV100 sits only five percentile points higher than the CMP 70HX, yet it is roughly 500% faster in OpenCL. This discrepancy suggests that the CMP 70HX's average score is buoyed by performance in other benchmark categories not shared in this comparison, while the two tests both cards took part in heavily favor the Volta architecture. The GV100 also holds a 2.4% lead over the NVIDIA A2 in its rival cluster, while the CMP 70HX is 1.8% ahead of the GeForce RTX 3070 Ti, indicating that both cards are competitive within their respective peer groups.

Architecture Differences

The two GPUs are built on fundamentally different architectures and process technologies. The Quadro GV100 uses the Volta architecture, fabricated on a 12 nm process at TSMC. It packs 21,100 million transistors onto an 815 mm² die, yielding a transistor density of 25.9 million per square millimeter. The CMP 70HX, in contrast, uses the Ampere architecture on an 8 nm process from Samsung, with 17,400 million transistors on a 392 mm² die, achieving a much higher density of 44.4 million per square millimeter. The CMP 70HX is therefore the more modern and denser design, but the GV100 compensates with a substantially larger die and more total transistors.

The memory subsystems diverge sharply. The GV100 comes with 32 GB of HBM2 on a 4096-bit bus, delivering 868.4 GB/s of bandwidth. The CMP 70HX has 8 GB of GDDR6X on a 256-bit bus, providing 608.3 GB/s. The GV100's bus width is 16 times wider, and its bandwidth advantage is 42.8%. Clock speeds tell a different story: the CMP 70HX has a base clock of 1365 MHz and a boost of 1395 MHz, while the GV100 runs at 1132 MHz base and 1627 MHz boost. The GV100 has the higher boost ceiling, but the CMP 70HX's memory runs at 1188 MHz with 19 Gbps effective, compared to the GV100's 848 MHz memory clock at 1696 Mbps effective.

Compute resources are heavily skewed toward the GV100. It packs 5,120 shading units, 320 TMUs, 128 ROPs, and 640 tensor cores. The CMP 70HX has 3,840 shading units, 120 TMUs, 64 ROPs, and 120 tensor cores, plus 30 RT cores. The GV100's pixel rate is 208.3 GPixel/s versus 89.28 GPixel/s, and its texture rate is 520.6 GTexel/s versus 167.4 GTexel/s. In FP32, the GV100 delivers 16.66 TFLOPS against the CMP 70HX's 10.71 TFLOPS. The FP16 picture is more complex: the GV100 offers 33.32 TFLOPS at a 2:1 ratio, while the CMP 70HX delivers 10.71 TFLOPS at a 1:1 ratio.

The CMP 70HX's Ampere architecture supports DirectX 12 Ultimate (12_2), while the GV100 is limited to DirectX 12 (12_1). Both cards support OpenGL 4.6 and Vulkan 1.4. The CMP 70HX is designed specifically for mining, with no display outputs, while the GV100 includes 4x DisplayPort 1.4a outputs. The GV100 uses a PCIe 3.0 x16 interface, whereas the CMP 70HX is restricted to PCIe 1.0 x4, a significant limitation for data transfer workloads.

The Verdict

The data points to a clear choice for compute-heavy workloads. The Quadro GV100 wins both head-to-head benchmarks by enormous margins, and its 32 GB of HBM2 memory with 868.4 GB/s bandwidth makes it the superior option for large datasets and memory-bound tasks. Its 640 tensor cores and 16.66 TFLOPS of FP32 performance further cement its position as the stronger general-purpose compute card. The GV100 also carries display outputs, PCIe 3.0 x16 connectivity, and DirectX 12 support, making it a functional workstation GPU. Its end-of-life production status and release date of March 2018 indicate it is an older design, but the benchmark data shows it remains highly competitive.

The CMP 70HX is a different kind of product entirely. With no display outputs, a PCIe 1.0 x4 interface, and a mining-specific generation label, it is clearly not intended for desktop or workstation use. Its 8 GB of GDDR6X memory and 10.71 TFLOPS of FP32 performance are respectable, but the benchmark results show it trailing the GV100 by 496.8% in OpenCL and 289.6% in Vulkan. Its advantages are limited to a smaller die, higher transistor density, a faster base clock, and support for DirectX 12 Ultimate. Its lower suggested PSU of 200 W, versus 600 W for the GV100, suggests it draws less power, though no TDP figure is recorded for the CMP 70HX.

Users seeking maximum compute performance, large memory capacity, or display functionality should choose the Quadro GV100. The data shows it is in a completely different performance class. Users constrained by power delivery or those specifically targeting mining workloads might consider the CMP 70HX, but the benchmark record offers no evidence that it outperforms the GV100 in any shared test. The GV100 is the stronger card by every measured metric in this comparison.
