GPU Comparison

NVIDIA’s CMP 70HX and GeForce RTX 3070 Ti share the same GA104 die, the same 8 nm Samsung process, and the same 8 GB of GDDR6X on a 256-bit bus, but they are built for entirely different jobs. The CMP 70HX is a mining card with no display outputs, while the RTX 3070 Ti is a full-featured gaming GPU. The benchmark data shows a decisive performance gap: the RTX 3070 Ti wins both head-to-head tests by massive margins, scoring 79% higher in OpenCL and 74.3% higher in Vulkan. However, the CMP 70HX still holds a slight edge in average benchmark score across all recorded tests, and both cards sit at the 75th percentile of all GPUs. This is a tale of two cards with identical silicon but wildly different execution.

Where Each One Wins

The RTX 3070 Ti wins every single benchmark where the two are directly compared. In Geekbench OpenCL, the 3070 Ti scores 119,718 versus the CMP 70HX’s 25,135, a 79% advantage. In Geekbench Vulkan, the 3070 Ti scores 139,541 versus 35,817, a 74.3% lead. There are no benchmark categories where the CMP 70HX comes out ahead in head-to-head testing. The CMP 70HX’s only statistical victory is in the aggregate average benchmark score, where it reaches 30,476 versus the 3070 Ti’s 29,945, a mere 1.8% difference according to the nearestRivals data. This is likely because the CMP 70HX’s limited benchmark set (only two tests) skews its average, while the 3070 Ti’s ten tests include demanding workloads like PassMark DirectX 10/11/12 and 3DMark Steel Nomad DX12.

For real-world use, the 3070 Ti is the clear winner for any task involving graphics output, gaming, or general compute. The CMP 70HX, with no display outputs and a PCIe 1.0 x4 interface, is designed solely for mining operations where raw compute throughput matters more than versatility. In the context of these benchmarks, the CMP 70HX’s performance is so far behind that it cannot be recommended for anything other than its intended purpose, and even then, the data suggests it is a weaker compute performer than the 3070 Ti.

FAQ

Q: Is the CMP 70HX faster than the RTX 3070 Ti in any benchmark?

A: No. The RTX 3070 Ti wins both head-to-head tests: Geekbench OpenCL (119,718 vs 25,135) and Geekbench Vulkan (139,541 vs 35,817). The CMP 70HX only edges ahead in the aggregate average benchmark score (30,476 vs 29,945), but that is not a direct comparison.

Q: Can I use the CMP 70HX for gaming?

A: No. The CMP 70HX has no display outputs, so it cannot connect to a monitor. It also uses a PCIe 1.0 x4 bus interface, which is far slower than the RTX 3070 Ti’s PCIe 4.0 x16. The data shows it is 74.3% behind the 3070 Ti in Vulkan, which is the API most relevant to modern gaming.

Q: Do both cards use the same memory configuration?

A: Yes. Both have 8 GB of GDDR6X memory on a 256-bit bus with 608.3 GB/s bandwidth and 19 Gbps effective speed. The memory clock is identical at 1188 MHz for both.

Q: What is the power draw difference?

A: The RTX 3070 Ti has a TDP of 290 W and a suggested PSU of 600 W. The CMP 70HX has no listed TDP, but its suggested PSU is 200 W. That is a significant difference in system power requirements.

Q: Which card has more shading units?

A: The RTX 3070 Ti has 6,144 shading units, while the CMP 70HX has 3,840. The 3070 Ti also has 192 TMUs and 96 ROPs versus the CMP 70HX’s 120 TMUs and 64 ROPs.

Q: Are these cards still in production?

A: No. Both are listed as end-of-life. The RTX 3070 Ti was released on 2021-05-30 and has a launch MSRP of 599 USD, while the CMP 70HX has no release date or launch MSRP in the data.

Head-to-Head Benchmarks

The two recorded head-to-head tests paint a stark picture. In Geekbench OpenCL, the RTX 3070 Ti scores 119,718 against the CMP 70HX’s 25,135. That is a delta of -79% from the CMP 70HX’s perspective, meaning the 3070 Ti delivers roughly four times the OpenCL performance. This is not a marginal difference, it is a generational gap in compute capability. The RTX 3070 Ti’s 21.75 TFLOPS of FP32 performance versus the CMP 70HX’s 10.71 TFLOPS explains much of this, as does the 3070 Ti’s higher base clock of 1575 MHz versus 1365 MHz.

The Vulkan test shows a similar story. The RTX 3070 Ti scores 139,541, while the CMP 70HX manages only 35,817, a 74.3% deficit for the mining card. Vulkan is the API used by many modern game engines and compute workloads, so this gap directly translates to real-world usability. The 3070 Ti’s 48 RT cores and 192 tensor cores (versus 30 and 120 on the CMP 70HX) contribute to its advantage, as does its higher pixel rate (169.9 GPixel/s vs 89.28 GPixel/s) and texture rate (339.8 GTexel/s vs 167.4 GTexel/s).

It is worth noting that the CMP 70HX’s average benchmark score of 30,476 is actually slightly higher than the 3070 Ti’s 29,945, according to the nearestRivals data. The RTX 3070 Ti’s closest rival is the RTX 5070 Mobile at 29,928 (0.1% difference), while the CMP 70HX’s closest rival is the Tesla M60 at 30,490 (0% difference). This suggests that the CMP 70HX’s limited benchmark set may overstate its overall capability relative to the 3070 Ti, which is tested across a broader range of workloads including DirectX 9/10/11/12 and 3DMark.

Specification Differences

The core specifications diverge sharply between these two cards. The RTX 3070 Ti has 6,144 shading units versus 3,840 on the CMP 70HX, a 60% increase. TMUs are 192 versus 120, and ROPs are 96 versus 64. RT cores are 48 versus 30, and tensor cores are 192 versus 120. Clock speeds differ significantly: the 3070 Ti runs at 1575 MHz base and 1770 MHz boost, while the CMP 70HX runs at 1365 MHz base and 1395 MHz boost. This translates to FP32 performance of 21.75 TFLOPS for the 3070 Ti versus 10.71 TFLOPS for the CMP 70HX.

Power requirements are a major differentiator. The RTX 3070 Ti has a TDP of 290 W and a suggested PSU of 600 W. The CMP 70HX has no TDP listed, but its suggested PSU is only 200 W. Both use a single 12-pin power connector and are dual-slot cards. The bus interface differs as well: the 3070 Ti uses PCIe 4.0 x16, while the CMP 70HX is stuck with PCIe 1.0 x4. Display outputs are the most obvious difference, the 3070 Ti has 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the CMP 70HX has none.

Physical dimensions are identical: both are 267 mm (10.5 inches) long and 112 mm (4.4 inches) tall. Both use the GA104 chip on an 8 nm Samsung process with 17,400 million transistors and a 392 mm² die size. Transistor density is the same at 44.4M / mm². Memory is identical as well: 8 GB GDDR6X on a 256-bit bus with 608.3 GB/s bandwidth.

Architecture Differences

Both cards are built on NVIDIA’s Ampere architecture using the GA104 chip, manufactured by Samsung on an 8 nm process. They share the same 17,400 million transistors and 392 mm² die size, with identical transistor density of 44.4M / mm². The foundry is the same, and both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The critical architectural difference is in how the silicon is configured. The RTX 3070 Ti uses nearly double the shading units, TMUs, and ROPs of the CMP 70HX. It also has 60% more RT cores (48 vs 30) and 60% more tensor cores (192 vs 120). The CMP 70HX appears to be a cut-down version of the same die, with its FP32 performance halved from 21.75 TFLOPS to 10.71 TFLOPS. The FP16 performance follows the same pattern, with both cards offering 1:1 FP16 to FP32 ratios.

Clock speeds also differ architecturally: the 3070 Ti boosts to 1770 MHz, while the CMP 70HX tops out at 1395 MHz. This 375 MHz difference at boost, combined with the core count disparity, explains the massive benchmark gap. The CMP 70HX’s PCIe 1.0 x4 interface is a severe bottleneck for any workload that transfers data over the bus, while the 3070 Ti’s PCIe 4.0 x16 provides ample bandwidth. Memory architecture is identical, but the CMP 70HX’s lower core configuration means it cannot utilize that bandwidth as effectively.

The Verdict

The data is unambiguous: the RTX 3070 Ti is the superior GPU in every measurable way. It wins both head-to-head benchmarks by margins of 74.3% and 79%, has more than double the FP32 throughput (21.75 TFLOPS vs 10.71 TFLOPS), and offers full display connectivity with HDMI 2.1 and DisplayPort 1.4a outputs. The 3070 Ti also has a robust 75th percentile ranking among all GPUs, matching the CMP 70HX, but does so across a much wider range of tests. The only numbers favoring the CMP 70HX are its lower suggested PSU (200 W vs 600 W) and its marginally higher average benchmark score (30,476 vs 29,945), which is a statistical artifact of its limited test set.

For anyone building a system that needs to output video, play games, or run general-purpose compute, the RTX 3070 Ti is the only choice. Its 599 USD launch MSRP is a single data point, but the performance gap justifies it on technical merits alone. The CMP 70HX, with no display outputs and a PCIe 1.0 x4 interface, is strictly a mining card, and even in that role, its compute performance lags far behind the 3070 Ti. The RTX 3070 Ti’s 48 RT cores and 192 tensor cores make it suitable for ray tracing and AI workloads, while the CMP 70HX’s reduced configuration offers none of that headroom. If both cards were available at similar prices, the 3070 Ti would be the obvious pick. The CMP 70HX’s only advantage is its lower power requirement, which might matter in dense mining rigs, but the benchmark data shows it is fundamentally a weaker product. Choose the RTX 3070 Ti unless you have a very specific mining-only use case and can tolerate a 74-79% performance deficit.
