GPU Comparison

The NVIDIA CMP 70HX and the NVIDIA GeForce RTX 2080 Ti are both end-of-life NVIDIA products, but they were built for entirely different purposes. The CMP 70HX is a dedicated mining GPU with no display outputs, while the RTX 2080 Ti is a flagship consumer graphics card from the GeForce 20-series. Benchmark data from the FACT PACK shows a decisive performance gap between the two, with the RTX 2080 Ti winning both head-to-head comparisons by a wide margin. The CMP 70HX sits at the 75th percentile among all GPUs, a position it shares with the RTX 2080 Ti, yet the raw scores tell a story of two very different performance classes.

Where Each One Wins

The performance split between these two cards is stark, with the RTX 2080 Ti claiming victories in every available benchmark comparison. The CMP 70HX records zero wins in the head-to-head data, while the RTX 2080 Ti takes both. This is not a close contest; the RTX 2080 Ti dominates in compute-oriented workloads and graphics API tests alike. In Geekbench OpenCL, the RTX 2080 Ti scores 128171 against the CMP 70HX’s 25135, a margin of 80.4%. The Vulkan result follows the same pattern, with the RTX 2080 Ti posting 132930 versus 35817 for the CMP 70HX, a 73.1% advantage.

For users seeking raw compute throughput, the RTX 2080 Ti is the clear choice. Its FP32 performance of 13.45 TFLOPS exceeds the CMP 70HX’s 10.71 TFLOPS, and its FP16 output of 26.90 TFLOPS is more than double the CMP 70HX’s 10.71 TFLOPS. The CMP 70HX, by contrast, is a specialized tool with no display outputs, meaning it cannot be used for gaming or any visual output tasks. Its only logical use case is mining, where its dual-slot design and single 12-pin power connector fit a specific deployment scenario. The RTX 2080 Ti, with its 1x HDMI 2.0, 3x DisplayPort 1.4a, and 1x USB Type-C outputs, is a fully functional graphics card for gaming, content creation, and general compute.

The RTX 2080 Ti also wins on memory capacity and interface bandwidth. It offers 11 GB of GDDR6 memory on a 352-bit bus, compared to the CMP 70HX’s 8 GB of GDDR6X on a 256-bit bus. The RTX 2080 Ti’s memory bandwidth of 616.0 GB/s edges out the CMP 70HX’s 608.3 GB/s, a narrow but real advantage. The CMP 70HX does use faster GDDR6X memory at 19 Gbps effective, versus the RTX 2080 Ti’s GDDR6 at 14 Gbps, but the wider bus on the RTX 2080 Ti compensates, resulting in slightly higher overall bandwidth.

Architecture Differences

The two cards are built on different architectures from different foundries, which explains much of their performance disparity. The CMP 70HX uses the GA104 chip based on the Ampere architecture, fabricated on an 8 nm process by Samsung. The RTX 2080 Ti uses the TU102 chip based on the older Turing architecture, fabricated on a 12 nm process by TSMC. The process node difference is significant: 8 nm allows for a smaller die and higher transistor density. The CMP 70HX’s die is 392 mm² and contains 17,400 million transistors, yielding a density of 44.4M per mm². The RTX 2080 Ti’s die is much larger at 754 mm² and contains 18,600 million transistors, but its density is only 24.7M per mm².

Despite the larger die, the RTX 2080 Ti has more of nearly every compute resource. It packs 4352 shading units, 272 texture mapping units (TMUs), and 88 render output units (ROPs). The CMP 70HX has 3840 shading units, 120 TMUs, and 64 ROPs. The RTX 2080 Ti also has more ray tracing cores (68 versus 30) and more tensor cores (544 versus 120). These differences translate directly into performance: the RTX 2080 Ti achieves a pixel rate of 136.0 GPixel/s and a texture rate of 420.2 GTexel/s, while the CMP 70HX manages 89.28 GPixel/s and 167.4 GTexel/s, respectively.

The CMP 70HX’s Ampere architecture does bring a notable feature: FP16 performance at a 1:1 ratio with FP32. The RTX 2080 Ti’s Turing architecture offers FP16 at a 2:1 ratio, meaning it can double its FP32 throughput when using FP16 instructions. This gives the RTX 2080 Ti a theoretical FP16 peak of 26.90 TFLOPS, far above the CMP 70HX’s 10.71 TFLOPS. The CMP 70HX also uses a PCIe 1.0 x4 interface, which is severely limited compared to the RTX 2080 Ti’s PCIe 3.0 x16 interface. This interface difference could bottleneck data transfer in some workloads, though the CMP 70HX’s mining focus likely minimizes the impact.

Head-to-Head Benchmarks

The head-to-head benchmark data is one-sided. In Geekbench OpenCL, the RTX 2080 Ti scores 128171, while the CMP 70HX scores 25135. The delta is -80.4% for the CMP 70HX, meaning it trails by over four-fifths. This is a massive gap that reflects the RTX 2080 Ti’s superior shading units, TMUs, and ROPs, as well as its higher boost clock of 1545 MHz versus the CMP 70HX’s 1395 MHz. In Geekbench Vulkan, the RTX 2080 Ti again wins with 132930 against 35817, a delta of -73.1%. The Vulkan test also shows the RTX 2080 Ti’s advantage in raw throughput, though the margin is slightly narrower than OpenCL.

The RTX 2080 Ti’s average benchmark score across all tests is 29783, while the CMP 70HX’s average is 30476. This is counterintuitive given the head-to-head results, but it reflects the different benchmark suites available for each card. The CMP 70HX only has two benchmarks in its record (Geekbench OpenCL and Vulkan), while the RTX 2080 Ti has ten, including several Passmark tests that likely skew its average lower. The RTX 2080 Ti’s Passmark scores are modest: 21548 in G3D, 10056 in GPU compute, and low scores in DirectX 9, 10, 11, and 12 tests. These legacy API tests pull down the average, whereas the CMP 70HX’s two modern API scores are relatively high for its class.

The percentile data further complicates the picture. Both cards sit at the 75th percentile among all GPUs, despite the RTX 2080 Ti’s dominant head-to-head wins. This suggests that the CMP 70HX’s benchmark scores, while lower than the RTX 2080 Ti’s in direct comparison, are still competitive with a wide range of GPUs in the overall database. The CMP 70HX’s nearest rivals include the NVIDIA Tesla M60 (average score 30490, delta 0%), the AMD Radeon RX 6700 (30433, delta 0.1%), and the AMD Radeon RX 6800 (30095, delta 1.3%). The RTX 2080 Ti’s nearest rivals include the NVIDIA GeForce RTX 3070 Ti (29945, delta -0.5%) and the AMD Radeon RX 6800 (30095, delta -1%).

Specification Differences

The specification sheets reveal several areas where the two cards diverge. The CMP 70HX has a base clock of 1365 MHz and a boost clock of 1395 MHz, while the RTX 2080 Ti has a base clock of 1350 MHz and a boost clock of 1545 MHz. The RTX 2080 Ti’s boost clock is 150 MHz higher, contributing to its performance edge. Memory differs in type, size, and bus width: the CMP 70HX uses 8 GB of GDDR6X on a 256-bit bus, while the RTX 2080 Ti uses 11 GB of GDDR6 on a 352-bit bus. The effective memory speeds are 19 Gbps for the CMP 70HX and 14 Gbps for the RTX 2080 Ti, but the RTX 2080 Ti’s wider bus gives it a slight bandwidth advantage at 616.0 GB/s versus 608.3 GB/s.

The RTX 2080 Ti has a TDP of 250 W and requires a 600 W suggested power supply, while the CMP 70HX has no listed TDP but suggests a 200 W PSU. The power connectors differ: the CMP 70HX uses a single 12-pin connector, while the RTX 2080 Ti uses two 8-pin connectors. Physical dimensions are similar in length (both 267 mm), but the RTX 2080 Ti is taller (116 mm versus 112 mm) and has a specified width of 35 mm, while the CMP 70HX’s width is not listed. Both are dual-slot cards.

The bus interface is a major differentiator. The CMP 70HX uses PCIe 1.0 x4, which is an unusual choice for a modern GPU and likely reflects its mining-specific design, where bandwidth is less critical. The RTX 2080 Ti uses PCIe 3.0 x16, providing 16 times the lanes and a much higher data transfer rate. The CMP 70HX has no display outputs, while the RTX 2080 Ti offers a full complement of video connections. The RTX 2080 Ti also has a launch MSRP of 999 USD, which can be stated as a single data point. The CMP 70HX has no launch MSRP listed.
