NVIDIA CMP 70HX vs NVIDIA TITAN V Comparison

Where Each One Wins

The benchmark data splits cleanly between these two cards, and the winner is not subtle. The NVIDIA TITAN V takes both recorded head-to-head tests, and by margins that are difficult to call competitive. In Geekbench OpenCL, the TITAN V scores 157,265 against the CMP 70HX's 25,135, a 525.7% advantage. In Geekbench Vulkan, the TITAN V posts 152,117 versus 35,817, a 324.7% lead. If the task is compute-heavy and runs through OpenCL or Vulkan, the TITAN V is the only rational choice from this pairing.

The CMP 70HX wins nowhere in the recorded data. It has zero head-to-head victories. However, its narrower role should be considered: it is a mining-focused card with no display outputs, so its absence of wins in general-purpose compute benchmarks does not mean it lacks purpose. Its nearest rivals include the NVIDIA Tesla M60 with a 0% delta, the AMD Radeon RX 6700 at 0.1%, the AMD Radeon RX 6800 at 1.3%, and the NVIDIA GeForce RTX 3070 Ti at 1.8%. Those deltas are tiny, meaning the CMP 70HX sits in a tight performance cluster around those cards. The TITAN V, by contrast, sits near the NVIDIA RTX A1000 (0.4% delta), the AMD Radeon HD 7970 (-0.5%), the NVIDIA RTX A2000 12 GB (0.6%), and the NVIDIA T1000 8 GB (-0.6%). Its average benchmark score is 34,355, while the CMP 70HX averages 30,476.

For a builder choosing between these two, the use case decides everything. If you need general compute, rendering, or any workload that touches OpenCL or Vulkan, the TITAN V is overwhelmingly faster. If you are assembling a mining rig where display output is irrelevant and power draw is a secondary concern, the CMP 70HX is the card designed for that exact job, even if its compute scores lag far behind.

Architecture Differences

The two cards come from different architectural generations and different foundries. The TITAN V uses the GV100 chip on TSMC's 12 nm process, while the CMP 70HX uses the GA104 chip on Samsung's 8 nm node. The transistor counts reflect this: the TITAN V packs 21,100 million transistors into an 815 mm² die, giving a density of 25.9M transistors per mm². The CMP 70HX has 17,400 million transistors on a 392 mm² die, with a much higher density of 44.4M per mm². The newer process node allows the smaller die to hold more transistors per area, but the TITAN V is the physically larger and more complex chip.

The TITAN V belongs to the Volta architecture, a design built around compute and tensor operations. It has 5,120 shading units, 320 TMUs, 96 ROPs, and 640 tensor cores. It has no dedicated ray tracing cores. The CMP 70HX is Ampere, with 3,840 shading units, 120 TMUs, 64 ROPs, 30 ray tracing cores, and 120 tensor cores. The TITAN V has more raw shading hardware, but the CMP 70HX adds ray tracing support and a more modern API feature set.

Memory differs fundamentally. The TITAN V uses 12 GB of HBM2 on a 3072-bit bus, yielding 651.3 GB/s of bandwidth. The CMP 70HX uses 8 GB of GDDR6X on a 256-bit bus, yielding 608.3 GB/s. The TITAN V's memory clock is 848 MHz (1696 Mbps effective), while the CMP 70HX runs at 1188 MHz (19 Gbps effective). Despite the older memory type, the TITAN V maintains higher bandwidth thanks to its enormous bus width.

Clock speeds favor the CMP 70HX in base terms, at 1365 MHz versus 1200 MHz, but the boost clocks are closer: 1395 MHz for the CMP 70HX and 1455 MHz for the TITAN V. The TITAN V actually boosts higher. Its pixel rate (139.7 GPixel/s) and texture rate (465.6 GTexel/s) dwarf the CMP 70HX's 89.28 GPixel/s and 167.4 GTexel/s. FP32 throughput is 14.90 TFLOPS for the TITAN V versus 10.71 TFLOPS for the CMP 70HX. FP16 follows the same pattern: 29.80 TFLOPS (2:1) for the TITAN V, 10.71 TFLOPS (1:1) for the CMP 70HX.

The CMP 70HX has no display outputs, a PCIe 1.0 x4 interface, and a single 12-pin power connector. The TITAN V has 1x HDMI 2.0 and 3x DisplayPort 1.4a, PCIe 3.0 x16, and uses 1x 6-pin plus 1x 8-pin. The CMP 70HX lists a suggested PSU of 200 W; the TITAN V lists 600 W. The TITAN V's TDP is 250 W, while the CMP 70HX has no recorded TDP.

Head-to-Head Benchmarks

The only two shared benchmarks are Geekbench OpenCL and Geekbench Vulkan, and the TITAN V dominates both. In OpenCL, the TITAN V scores 157,265, and the CMP 70HX scores 25,135. That is a 525.7% delta. To put that in perspective, the CMP 70HX would need to more than quintuple its score to match the TITAN V. The TITAN V's nearest rival, the NVIDIA RTX A1000, averages 34,207, which is only 0.4% away from the TITAN V's own average. The CMP 70HX's OpenCL score sits far below even its own average of 30,476, which means its Vulkan result of 35,817 is the stronger of its two recorded scores.

In Vulkan, the TITAN V scores 152,117 against 35,817. The delta is 324.7%. This is still a massive gap, but smaller than the OpenCL margin. The TITAN V's Vulkan result is close to its OpenCL result, suggesting consistent performance across API types. The CMP 70HX's Vulkan score is significantly higher than its OpenCL score, indicating that the card is better suited to Vulkan workloads. Even so, the TITAN V beats it by more than a factor of four.

Look at the average benchmark scores to see how these cards sit in the broader database. The TITAN V averages 34,355 and ranks in the 79th percentile of all GPUs. The CMP 70HX averages 30,476 and ranks in the 75th percentile. The gap in percentile is small, but the gap in the two shared tests is enormous. This is because the CMP 70HX's limited benchmark set (only two tests) pulls its average up relative to its actual performance in those tests, while the TITAN V has ten recorded benchmarks that include lower DirectX scores. The TITAN V's Passmark scores, for example, range from 81 in DirectX 12 to 19,805 in G3D, which drags its average down but does not change its dominance in the shared tests.

The Verdict

The data points in one direction for general compute. The NVIDIA TITAN V is 525.7% faster in OpenCL and 324.7% faster in Vulkan than the NVIDIA CMP 70HX. It also has more shading units, more TMUs, more ROPs, more tensor cores, more memory, and higher bandwidth. If your workload uses OpenCL or Vulkan, there is no argument for the CMP 70HX.

The CMP 70HX exists for a different job. It has no display outputs, a PCIe 1.0 x4 interface, and a 200 W suggested PSU. Its nearest rivals include the RTX 3070 Ti and RX 6800, with deltas of 1.8% or less. That tells you it is a competent performer in its own class, but its class is mining, not general computing. The TITAN V's nearest rivals are professional and older cards like the RTX A1000 and HD 7970, which reflects its position as a compute-oriented flagship.

Who should pick the TITAN V? Anyone running OpenCL or Vulkan workloads, anyone needing display outputs, anyone who wants 12 GB of memory on a 3072-bit bus, and anyone who needs 14.90 TFLOPS of FP32 performance. Who should pick the CMP 70HX? Only someone building a mining rig that does not require display output, does not need PCIe bandwidth beyond 1.0 x4, and can live with 8 GB of GDDR6X. The benchmark record is clear: the TITAN V wins every shared test, and the CMP 70HX wins none.
