NVIDIA CMP 70HX vs NVIDIA GeForce GTX TITAN X Comparison

Head-to-Head Benchmarks

The data is unambiguous: the NVIDIA GeForce GTX TITAN X wins both recorded head-to-head benchmark comparisons against the NVIDIA CMP 70HX. In OpenCL compute workloads, the TITAN X scores 41,471 points versus 25,135 for the CMP 70HX, a decisive 65% advantage. The Vulkan results show a similar, though less extreme, gap: the TITAN X posts 49,397 points against 35,817, which is a 37.9% lead. These are not marginal victories; the TITAN X is faster in both APIs by a substantial margin, despite being an older design with a different architectural foundation.

The average benchmark scores reinforce this picture. The TITAN X holds an average benchmark score of 36,530, placing it at the 80th percentile of all GPUs in the database. The CMP 70HX averages 30,476, which lands at the 75th percentile. The 6,054-point difference in average scores is consistent with the head-to-head deltas, confirming that the TITAN X is the stronger overall performer in the recorded data.

Context from the nearest rivals adds nuance. The TITAN X sits alongside the AMD Radeon RX 5300M (average score 36,529, delta 0%), the NVIDIA T1000 (36,289, 0.7% behind), the AMD Radeon PRO W6400 (37,157, 1.7% ahead), and the AMD Radeon Pro Duo (35,860, 1.9% behind). This clustering shows the TITAN X is competitive with a range of modern and professional cards, with the PRO W6400 edging it out by less than 2%. The CMP 70HX, meanwhile, is bracketed by the NVIDIA Tesla M60 (30,490, 0% delta), the AMD Radeon RX 6700 (30,433, 0.1% behind), the AMD Radeon RX 6800 (30,095, 1.3% behind), and the NVIDIA GeForce RTX 3070 Ti (29,945, 1.8% behind). The CMP 70HX leads its nearest rivals by a narrow margin, but that group is a full tier below the TITAN X's competition.

Breaking down the individual benchmark wins, the TITAN X's OpenCL advantage of 65% is the single largest gap in the comparison. The Vulkan delta of 37.9% is smaller but still commanding. The CMP 70HX has no recorded wins in any head-to-head test, and it lacks a Geekbench Metal result entirely, while the TITAN X records 18,723 points in Metal. That missing data point itself signals a difference in intended workload, but on the tests both cards share, the TITAN X is clearly ahead.

The Verdict

From the recorded data, the NVIDIA GeForce GTX TITAN X is the superior GPU. It wins both head-to-head benchmarks, holds a higher average benchmark score (36,530 versus 30,476), and ranks higher in the overall percentile distribution (80th versus 75th). If the choice is purely about compute performance in OpenCL or Vulkan, the TITAN X is the card to select. The 65% lead in OpenCL is the kind of margin that changes decisions for compute-heavy workloads.

The CMP 70HX does not win in any recorded category. Its only advantages appear in architectural characteristics, not performance. It has more shading units (3,840 versus 3,072), a smaller die (392 mm² versus 601 mm²), and a much higher transistor density (44.4M per mm² versus 13.3M per mm²), but these do not translate into benchmark wins. The data shows that architectural efficiency does not overcome the TITAN X's raw output in the tests conducted.

The production status of both cards is end-of-life, so neither is a forward-looking purchase. The TITAN X has a known release date of March 16, 2015, and a launch MSRP of 999 USD, while the CMP 70HX has no recorded release date or MSRP. For anyone evaluating these two based on the database, the verdict is straightforward: the TITAN X outperforms the CMP 70HX in every measured benchmark, and the CMP 70HX offers no compensating performance edge.

Where Each One Wins

The TITAN X wins in compute-bound scenarios that rely on OpenCL. With a 65% lead in that API, it is the better option for general-purpose GPU compute tasks that leverage OpenCL, including many scientific, rendering, and data-processing workloads. Its Vulkan advantage of 37.9% also makes it the stronger choice for applications that use Vulkan for compute or graphics, though the margin is smaller than in OpenCL. The TITAN X also has display outputs, including 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.2, so it can drive displays directly, making it usable in conventional desktop and workstation setups.

The CMP 70HX has no recorded wins, so there is no benchmark category where the data supports choosing it for performance. Its strength lies in its architecture and feature set, not its measured output. It includes 30 ray tracing cores and 120 tensor cores, which the TITAN X lacks entirely. For workloads that depend on ray tracing or tensor core acceleration, the CMP 70HX is structurally capable while the TITAN X is not, but no benchmark in the database confirms this advantage. It also has a lower suggested PSU requirement of 200 W, compared to the TITAN X's 600 W, which may make it easier to integrate into systems with smaller power supplies. The CMP 70HX has no display outputs, which signals it is designed for mining or headless compute, not interactive use.

The use-case split is therefore clear. The TITAN X is the pick for anyone running OpenCL or Vulkan workloads on a card that can also output to a monitor. The CMP 70HX is the pick only for scenarios that specifically require its tensor or ray tracing hardware, or where the lower PSU recommendation matters, and even then the database provides no performance evidence to back that choice.

Architecture Differences

The architectural divide between these two cards is significant. The TITAN X is built on the GM200 chip using Maxwell 2.0 architecture, fabricated on a 28 nm process at TSMC. It contains 8,000 million transistors on a 601 mm² die, giving a transistor density of 13.3 million per mm². The CMP 70HX uses the GA104 chip with Ampere architecture, built on an 8 nm process at Samsung. It packs 17,400 million transistors into a 392 mm² die, achieving a transistor density of 44.4 million per mm². The CMP 70HX is the denser, more modern design, but the TITAN X's larger die and older process do not hold it back in the benchmarks.

Core configuration differs sharply. The TITAN X has 3,072 shading units, 192 texture mapping units, and 96 render output units. The CMP 70HX has 3,840 shading units, 120 TMUs, and 64 ROPs. The CMP 70HX has more shaders but fewer TMUs and ROPs. The TITAN X also has no ray tracing cores and no tensor cores, while the CMP 70HX includes 30 ray tracing cores and 120 tensor cores, a feature set the older Maxwell card cannot match. The CMP 70HX also supports FP16 at a 1:1 ratio with FP32, posting 10.71 TFLOPS in both, whereas the TITAN X has no recorded FP16 figure and delivers 6.691 TFLOPS FP32.

The memory subsystems reflect different priorities. The TITAN X uses 12 GB of GDDR5 on a 384-bit bus, with 336.6 GB/s bandwidth. The CMP 70HX uses 8 GB of GDDR6X on a 256-bit bus, with 608.3 GB/s bandwidth. The CMP 70HX's bandwidth is nearly double, which is relevant for memory-intensive workloads, but the benchmark results do not show this translating into a win. Clock behavior also differs: the TITAN X runs at a 1000 MHz base and 1089 MHz boost, while the CMP 70HX runs at 1365 MHz base and 1395 MHz boost. The CMP 70HX is clocked higher, yet still loses in the recorded tests.

Specification Differences

The two cards differ across nearly every specification category. The TITAN X is a GeForce 900 generation product, while the CMP 70HX belongs to the Mining GPUs generation. Process nodes differ: 28 nm for the TITAN X versus 8 nm for the CMP 70HX. Transistor counts are 8,000 million versus 17,400 million, and die sizes are 601 mm² versus 392 mm². Transistor density is 13.3M per mm² for the TITAN X and 44.4M per mm² for the CMP 70HX.

Clock speeds diverge. The TITAN X has a 1000 MHz base and 1089 MHz boost; the CMP 70HX has a 1365 MHz base and 1395 MHz boost. Memory clocks are 1753 MHz (7 Gbps effective) for the TITAN X and 1188 MHz (19 Gbps effective) for the CMP 70HX. Memory capacity, type, and bus width all differ: 12 GB GDDR5 on 384-bit versus 8 GB GDDR6X on 256-bit. Bandwidth is 336.6 GB/s versus 608.3 GB/s.

Shading units, TMUs, and ROPs differ as noted: 3,072/192/96 for the TITAN X and 3,840/120/64 for the CMP 70HX. The CMP 70HX adds 30 ray tracing cores and 120 tensor cores, which the TITAN X does not have. Pixel rates are 104.5 GPixel/s for the TITAN X and 89.28 GPixel/s for the CMP 70HX. Texture rates are 209.1 GTexel/s versus 167.4 GTexel/s. FP32 output is 6.691 TFLOPS for the TITAN X and 10.71 TFLOPS for the CMP 70HX, with the CMP 70HX also recording 10.71 TFLOPS FP16.

Power and connectivity differ. The TITAN X has a TDP of 250 W and uses 1x 6-pin plus 1x 8-pin power connectors, with a suggested PSU of 600 W. The CMP 70HX has no recorded TDP, uses a single 12-pin connector, and has a suggested PSU of 200 W. The TITAN X uses PCIe 3.0 x16, while the CMP 70HX uses PCIe 1.0 x4, a major interface difference.
