Architecture Differences

The CMP 30HX is built on the TU116 chip using the Turing architecture, while the RTX 4070 Ti uses the AD104 chip with the Ada Lovelace architecture. The CMP 30HX belongs to the Mining GPUs generation, whereas the RTX 4070 Ti is part of the GeForce 40-series and the GeForce 40 generation.

The manufacturing process separates the two significantly. The CMP 30HX uses a 12 nm process at TSMC, with 6,600 million transistors on a 284 mm² die. The RTX 4070 Ti uses a 5 nm process at TSMC, packing 35,800 million transistors into a 294 mm² die. The transistor density rises from 23.2M per mm² on the CMP 30HX to 121.8M per mm² on the RTX 4070 Ti, a more than fivefold increase in packing density.

The memory subsystems differ in type and speed. The CMP 30HX has 6 GB of GDDR6 memory on a 192 bit bus, with 1750 MHz memory clock and 14 Gbps effective speed, yielding 336.0 GB/s bandwidth. The RTX 4070 Ti has 12 GB of GDDR6X memory on the same 192 bit bus width, with 1313 MHz memory clock and 21 Gbps effective speed, yielding 504.2 GB/s bandwidth. The bus width is identical, but the newer memory type and higher effective speed give the RTX 4070 Ti substantially more bandwidth.

The RTX 4070 Ti includes hardware features absent from the CMP 30HX. It has 60 RT cores and 240 tensor cores, while the CMP 30HX lists neither. The shading unit count jumps from 1408 on the CMP 30HX to 7680 on the RTX 4070 Ti, and the TMU count rises from 88 to 240. ROPs increase from 48 to 80.

The interface and output configuration also differ. The CMP 30HX uses a PCIe 1.0 x4 bus interface and has no display outputs, a design choice consistent with its mining purpose. The RTX 4070 Ti uses PCIe 4.0 x16 and provides 1x HDMI 2.1 and 3x DisplayPort 1.4a outputs. The CMP 30HX draws 125 W with a single 8-pin connector and a suggested PSU of 300 W. The RTX 4070 Ti draws 285 W, uses a single 16-pin connector, and suggests a 600 W PSU.

Head-to-Head Benchmarks

The database includes two shared benchmark tests between these cards: Geekbench OpenCL and Geekbench Vulkan. The RTX 4070 Ti wins both.

In Geekbench OpenCL, the CMP 30HX scores 65199, while the RTX 4070 Ti scores 176953. The delta is 63.2% in favor of the RTX 4070 Ti. This is not a narrow margin; the RTX 4070 Ti delivers roughly 2.7 times the OpenCL score of the CMP 30HX.

In Geekbench Vulkan, the gap widens. The CMP 30HX scores 62484, while the RTX 4070 Ti scores 213808. The delta is 70.8% in favor of the RTX 4070 Ti. The RTX 4070 Ti's Vulkan score is approximately 3.4 times that of the CMP 30HX.

The CMP 30HX wins none of the shared tests. The RTX 4070 Ti wins both, giving it a 2 to 0 record in the head-to-head comparison. The delta percentages are large in both tests, indicating a consistent and substantial performance advantage rather than a workload-specific edge.

The RTX 4070 Ti's additional benchmark results provide context for its broader performance profile. It scores 5024 in 3DMark Steel Nomad DX12, 31624 in Passmark G3D, 18396 in Passmark GPU Compute, and 1200 in Passmark G2D. Its DirectX legacy scores include 352 in Passmark DX9, 288 in DX11, 187 in DX10, and 116 in DX12. These figures are not directly comparable to the CMP 30HX, which has no corresponding entries in the database, but they indicate where the RTX 4070 Ti's strengths lie across different API generations.

Specification Differences

The two cards differ on nearly every specification field. The process node moves from 12 nm to 5 nm. Transistor count rises from 6,600 million to 35,800 million. Die size is similar, 284 mm² versus 294 mm², but density changes from 23.2M to 121.8M per mm².

Clock speeds differ substantially. The CMP 30HX has a base clock of 1530 MHz and a boost clock of 1785 MHz. The RTX 4070 Ti has a base clock of 2310 MHz and a boost clock of 2610 MHz. Memory clock also differs: 1750 MHz with 14 Gbps effective on the CMP 30HX, versus 1313 MHz with 21 Gbps effective on the RTX 4070 Ti.

Memory capacity doubles from 6 GB to 12 GB, and the type changes from GDDR6 to GDDR6X. Bus width remains 192 bit for both, but bandwidth increases from 336.0 GB/s to 504.2 GB/s.

Compute resources scale upward across the board. Shading units go from 1408 to 7680. TMUs go from 88 to 240. ROPs go from 48 to 80. The RTX 4070 Ti adds 60 RT cores and 240 tensor cores, which the CMP 30HX lacks entirely. Pixel rate rises from 85.68 GPixel/s to 208.8 GPixel/s. Texture rate rises from 157.1 GTexel/s to 626.4 GTexel/s. FP32 throughput rises from 5.027 TFLOPS to 40.09 TFLOPS. FP16 throughput rises from 10.05 TFLOPS (2:1) to 40.09 TFLOPS (1:1).

Power requirements scale as well. TDP goes from 125 W to 285 W. The power connector changes from 1x 8-pin to 1x 16-pin. Suggested PSU goes from 300 W to 600 W. Physical dimensions change: length from 229 mm to 285 mm, height nearly identical at 111 mm versus 112 mm, width from 35 mm to 42 mm. Both are dual-slot cards.

The bus interface changes from PCIe 1.0 x4 to PCIe 4.0 x16. Display outputs go from none to 1x HDMI 2.1 and 3x DisplayPort 1.4a. DirectX support moves from 12 (12_1) to 12 Ultimate (12_2). The release dates differ, with the CMP 30HX released earlier and the RTX 4070 Ti later, and the production status of both is end-of-life.

The Verdict

The data points to a decisive performance hierarchy between these two cards. The RTX 4070 Ti beats the CMP 30HX by 63.2% in Geekbench OpenCL and by 70.8% in Geekbench Vulkan. These are the only shared benchmarks in the database, and the RTX 4070 Ti wins both by wide margins.

The architectural differences explain the gap. The RTX 4070 Ti has 5.5 times the shading units, 2.7 times the TMUs, 1.7 times the ROPs, and 8 times the FP32 throughput of the CMP 30HX. It also has dedicated RT and tensor cores, which the CMP 30HX does not have at all. The memory bandwidth advantage of 504.2 GB/s versus 336.0 GB/s further separates the two.

The CMP 30HX's higher average benchmark score of 63842 versus 44795 for the RTX 4070 Ti is a statistical artifact of its limited benchmark pool, not an indication of real-world superiority. The CMP 30HX has only two Geekbench entries, both of which it loses by large margins. The RTX 4070 Ti's average is dragged down by its inclusion of legacy Passmark tests, where it scores in the hundreds, alongside its strong 3DMark and Geekbench results.

The RTX 4070 Ti is the clear choice for any workload that can use its compute resources, its memory bandwidth, or its RT and tensor core capabilities. The CMP 30HX offers no benchmark win in the shared tests, and its lack of display outputs limits its usefulness to compute or mining scenarios only.

Where Each One Wins

The RTX 4070 Ti wins in every shared benchmark category. Its Geekbench Vulkan result of 213808 is particularly strong, suggesting excellent performance in Vulkan-based workloads. Its Geekbench OpenCL result of 176953 indicates robust general-purpose compute capability. The 3DMark Steel Nomad DX12 score of 5024 and Passmark G3D score of 31624 further support its position as a capable graphics and compute card.

The CMP 30HX has no benchmark wins in the head-to-head comparison. Its Geekbench scores of 65199 in OpenCL and 62484 in Vulkan are respectable for its architecture and power envelope, but they fall far short of the RTX 4070 Ti. Its lower TDP of 125 W and single 8-pin power connector suggest it fits into systems with less power delivery headroom, but the database does not contain power consumption measurements to confirm operational efficiency comparisons.

For users prioritizing raw compute throughput, the RTX 4070 Ti's 40.09 TFLOPS FP32 and 40.09 TFLOPS FP16 (1:1) are the strongest numbers in this comparison. For users prioritizing memory bandwidth, the RTX 4070 Ti's 504.2 GB/s is the clear winner. For users who need display outputs, the CMP 30HX has none, making the RTX 4070 Ti the only option with 1x HDMI 2.1 and 3x DisplayPort 1.4a.

The RTX 4070 Ti also supports DirectX 12 Ultimate, which includes features beyond the DirectX 12 (12_1) level of the CMP 30HX. Combined with its RT and tensor cores, the RTX 4070 Ti is positioned for modern graphics workloads and AI-adjacent compute tasks. The CMP 30HX, with its mining-oriented design, lacks those capabilities entirely.
