GPU Comparison

The NVIDIA CMP 50HX and the NVIDIA GeForce RTX 4070 Ti are separated by more than just their release dates. The CMP 50HX is a Turing-era product built for a specific, now-defunct purpose, while the RTX 4070 Ti is a mainstream Ada Lovelace graphics card. The benchmark data shows a decisive performance gap, but the underlying architectural differences explain why these two cards exist in entirely different contexts. The CMP 50HX has an average benchmark score of 51,790, placing it in the 86th percentile of all GPUs, while the RTX 4070 Ti averages 44,795, placing it in the 84th percentile. These aggregate scores are close, but the head-to-head results tell a very different story, with the RTX 4070 Ti dominating in the two tests where both cards were measured.

Where Each One Wins

The CMP 50HX wins no benchmark comparisons against the RTX 4070 Ti. In the two shared tests, the RTX 4070 Ti takes a commanding lead. In Geekbench OpenCL, the CMP 50HX scores 56,135, while the RTX 4070 Ti scores 176,953, a delta of -68.3% in favor of the newer card. In Geekbench Vulkan, the gap widens further: the CMP 50HX scores 47,445 versus the RTX 4070 Ti’s 213,808, a delta of -77.8%. These are not marginal wins; they represent a generational leap in compute throughput.

The CMP 50HX does, however, hold its own in the broader competitive landscape. Its nearest rival is the AMD Radeon RX 6900 XT, with an average score of 50,951 and a delta of 1.6%, meaning the CMP 50HX is only slightly ahead. It also edges out the AMD Radeon RX Vega 64 by 3.6% and the NVIDIA GeForce RTX 5070 Ti by 3.7%. This suggests that while the CMP 50HX is uncompetitive against the RTX 4070 Ti, it remains a respectable performer in its own right, likely due to its high compute density.

The RTX 4070 Ti’s wins are not limited to the head-to-head. Its nearest rival is the NVIDIA GeForce RTX 5090 Mobile, with a delta of only -0.8%, meaning the RTX 4070 Ti is essentially tied with a mobile flagship. It also trails the AMD Radeon Pro 5500 XT by 1.3% and the Intel Arc A730M by 1.7%, while leading the NVIDIA RTX A6000 by 1.6%. The picture is one of a card that trades blows with top-tier mobile and workstation parts, but utterly outclasses a mining-specific Turing chip.

Architecture Differences

The architectural gap is the root cause of the performance disparity. The CMP 50HX uses the TU102 chip on TSMC’s 12 nm process, with 18,600 million transistors on a die size of 754 mm². This yields a transistor density of 24.7 million per mm². The RTX 4070 Ti, by contrast, uses the AD104 chip on TSMC’s 5 nm process, packing 35,800 million transistors into a much smaller 294 mm² die, achieving a density of 121.8 million per mm². The newer process allows for more than double the transistor count in less than half the silicon area.

Cores and compute units also differ sharply. The CMP 50HX has 3,584 shading units, 192 texture mapping units, and 80 ROPs. The RTX 4070 Ti nearly doubles the shading units to 7,680, increases TMUs to 240, and keeps ROPs at 80. The RTX 4070 Ti also has 60 ray tracing cores and 240 tensor cores, while the CMP 50HX has 56 RT cores and 448 tensor cores. The CMP 50HX actually has more tensor cores, but the RTX 4070 Ti’s are more advanced, and its FP16 performance is rated at 40.09 TFLOPS (1:1), matching its FP32 throughput. The CMP 50HX offers FP16 at 22.15 TFLOPS (2:1), indicating a different compute approach.

The memory subsystem is another major divergence. The CMP 50HX has 10 GB of GDDR6 on a 320-bit bus, delivering 560.0 GB/s of bandwidth. The RTX 4070 Ti has 12 GB of GDDR6X on a 192-bit bus, providing 504.2 GB/s. Despite the narrower bus, the faster GDDR6X memory keeps bandwidth competitive. The CMP 50HX also lacks any display outputs, while the RTX 4070 Ti includes 1x HDMI 2.1 and 3x DisplayPort 1.4a, reflecting their different intended uses.

Specification Differences

The most striking difference is the process node: the CMP 50HX uses 12 nm, while the RTX 4070 Ti uses 5 nm. This leads to a transistor count of 18,600 million versus 35,800 million, and a die size of 754 mm² versus 294 mm². Transistor density jumps from 24.7M per mm² to 121.8M per mm².

Clock speeds also diverge significantly. The CMP 50HX has a base clock of 1350 MHz and a boost of 1545 MHz, while the RTX 4070 Ti boosts to 2610 MHz from a base of 2310 MHz. Memory clocks differ as well: the CMP 50HX runs at 1750 MHz (14 Gbps effective), while the RTX 4070 Ti runs at 1313 MHz (21 Gbps effective).

Compute resources are heavily skewed toward the RTX 4070 Ti. It has 7,680 shading units, 240 TMUs, and 60 RT cores, versus the CMP 50HX’s 3,584 shading units, 192 TMUs, and 56 RT cores. The CMP 50HX has 448 tensor cores versus 240, and its FP32 throughput is 11.07 TFLOPS against the RTX 4070 Ti’s 40.09 TFLOPS. Pixel rate is 123.6 GPixel/s versus 208.8 GPixel/s, and texture rate is 296.6 GTexel/s versus 626.4 GTexel/s.

Memory size, type, and bus width differ: 10 GB GDDR6 on a 320-bit bus versus 12 GB GDDR6X on a 192-bit bus. Bandwidth is 560.0 GB/s versus 504.2 GB/s. Power draw is 250 W versus 285 W, with the CMP 50HX using 2x 8-pin connectors and the RTX 4070 Ti using 1x 16-pin. Both suggest a 600 W PSU. The CMP 50HX has a PCIe 1.0 x4 interface and no display outputs, while the RTX 4070 Ti uses PCIe 4.0 x16 and has full display outputs. Dimensions also differ: the CMP 50HX is 267 mm long, 116 mm high, and 35 mm wide, while the RTX 4070 Ti is 285 mm long, 112 mm high, and 42 mm wide.

Head-to-Head Benchmarks

The Geekbench OpenCL test shows a massive win for the RTX 4070 Ti. With a score of 176,953 against the CMP 50HX’s 56,135, the delta is -68.3%. This means the RTX 4070 Ti delivers roughly three times the OpenCL compute performance. The CMP 50HX’s 11.07 TFLOPS FP32 figure is simply outmatched by the RTX 4070 Ti’s 40.09 TFLOPS, which explains the near-3x gap.

The Geekbench Vulkan test is even more lopsided. The RTX 4070 Ti scores 213,808, while the CMP 50HX manages 47,445. The delta here is -77.8%, meaning the RTX 4070 Ti is over 4.5 times faster in this API. Vulkan performance benefits from the RTX 4070 Ti’s higher shading unit count and more efficient architecture, as well as its ability to handle modern workloads with better parallelism.

The CMP 50HX’s only consolation is its aggregate score. Its average of 51,790 is higher than the RTX 4070 Ti’s 44,795, but this is misleading. The RTX 4070 Ti has been tested in a wider range of benchmarks, including 3DMark Steel Nomad (5,024), Passmark G3D (31,624), and Passmark GPU Compute (18,396), while the CMP 50HX has only two recorded scores. The CMP 50HX’s high average is a function of its limited test set, not superior performance. In direct competition, the RTX 4070 Ti wins both tests decisively, and the winsA/winsB tally confirms this: 0 wins for the CMP 50HX, 2 for the RTX 4070 Ti.
