NVIDIA CMP 70HX vs NVIDIA T600 Mobile Comparison

The NVIDIA T600 Mobile and NVIDIA CMP 70HX are two very different products that happen to share a manufacturer. One is a low-power mobile workstation GPU, while the other is a dual-slot mining card with no display outputs. Benchmark data reveals a split decision, with each card claiming a victory in one of the two recorded tests.

Head-to-Head Benchmarks

The most striking result in the data is the T600 Mobile’s dominance in the Geekbench OpenCL test. It scores 35,486 points, a full 41.2% higher than the CMP 70HX’s 25,135. This is a massive margin, suggesting that the T600 Mobile’s architecture is far better optimized for the OpenCL workload. This win is even more impressive given that the T600 Mobile is a 40 W part with 896 shading units, while the CMP 70HX is a dual-slot card with 3,840 shading units. The raw compute advantage of the CMP 70HX, which boasts 10.71 TFLOPS of FP32 performance versus the T600 Mobile’s 2.527 TFLOPS, does not translate into OpenCL success here.

The tables turn completely in the Geekbench Vulkan test. The CMP 70HX scores 35,817 points, beating the T600 Mobile’s 30,211 by 15.7%. This is a significant reversal, indicating that the newer Ampere architecture of the CMP 70HX handles Vulkan workloads far more efficiently. The T600 Mobile’s Turing architecture, while strong in OpenCL, appears to be outpaced in this modern graphics API. The result is a 1-1 tie in the head-to-head, with each card winning by a substantial double-digit percentage.

Looking at the average benchmark scores provides a broader picture. The T600 Mobile averages 32,849 points, which places it at the 77th percentile of all GPUs. Its nearest rivals are the NVIDIA P104-100 (32,982 points, -0.4% delta) and the NVIDIA T550 Mobile (33,161 points, -0.9% delta). This places the T600 Mobile in a tightly contested performance bracket. The CMP 70HX averages 30,476 points, putting it at the 75th percentile. Its closest competitors are the NVIDIA Tesla M60 (30,490 points, 0% delta) and the AMD Radeon RX 6700 (30,433 points, 0.1% delta). While the percentile rankings are similar, the CMP 70HX sits in a slightly lower absolute performance tier. The T600 Mobile’s average score is 7.8% higher than the CMP 70HX’s, a gap that is consistent with the large OpenCL victory.

The data suggests that these two cards are not direct competitors in any meaningful sense. The T600 Mobile’s wins are driven by a specific API workload, while the CMP 70HX’s win is in another. Their benchmark profiles are nearly inverted, which points to fundamentally different design goals. The T600 Mobile’s strong OpenCL showing could be a boon for compute-heavy professional applications, while the CMP 70HX’s Vulkan performance is likely geared toward graphics rendering tasks, even if its primary purpose was mining.

The Verdict

The choice between these two cards depends entirely on the intended workload, as their benchmark results show opposing strengths. For users prioritizing OpenCL compute performance, the NVIDIA T600 Mobile is the clear winner. Its 41.2% lead in that specific test is a decisive advantage that outweighs its loss in Vulkan. The data shows it is also the better overall performer, with a higher average score and a higher percentile ranking (77th vs 75th).

The NVIDIA CMP 70HX is the pick for Vulkan-centric applications. Its 15.7% victory in that benchmark demonstrates a clear architectural superiority for that API. However, its lower average score and its position as a mining-specific product with no display outputs make it a niche choice. The T600 Mobile, with its 40 W TDP and mobile form factor, is a more versatile and broadly capable part. The data indicates that for general-purpose use or OpenCL-heavy tasks, the T600 Mobile is the superior product. For a specific Vulkan rendering pipeline, the CMP 70HX would be the better option, despite its overall lower average performance.

Specification Differences

The two cards have fundamental differences in their memory and power specifications. The T600 Mobile uses 4 GB of GDDR6 memory on a 128-bit bus, providing a bandwidth of 192.0 GB/s. The CMP 70HX uses 8 GB of GDDR6X memory on a 256-bit bus, delivering a much higher 608.3 GB/s of bandwidth. The CMP 70HX also has a significantly higher memory clock at 19 Gbps effective, versus the T600 Mobile’s 12 Gbps effective.

The compute configurations are also vastly different. The T600 Mobile has 896 shading units, 56 TMUs, and 32 ROPs. The CMP 70HX has 3,840 shading units, 120 TMUs, and 64 ROPs. The CMP 70HX also includes 30 ray tracing cores and 120 tensor cores, while the T600 Mobile has none of either. The T600 Mobile’s TDP is listed at 40 W, while the CMP 70HX has no TDP listed but suggests a 200 W power supply. The CMP 70HX uses a single 12-pin power connector, while the T600 Mobile has no power connectors. The bus interface also differs, with the T600 Mobile using PCIe 3.0 x16 and the CMP 70HX using the older PCIe 1.0 x4.

Architecture Differences

The architectural divide is significant. The T600 Mobile is built on the Turing architecture with the TU117 chip, fabricated on a 12 nm process at TSMC. The CMP 70HX uses the Ampere architecture with the GA104 chip, fabricated on an 8 nm process at Samsung. This newer process node allows for a massive increase in transistor count: the GA104 has 17,400 million transistors compared to the TU117’s 4,700 million. The die size also grows from 200 mm² to 392 mm², with transistor density nearly doubling from 23.5M / mm² to 44.4M / mm².

These architectural differences explain the performance variance. The CMP 70HX supports DirectX 12 Ultimate (12_2), while the T600 Mobile is limited to DirectX 12 (12_1). The inclusion of ray tracing and tensor cores on the CMP 70HX is an Ampere-generation feature that the older Turing chip lacks. The CMP 70HX also offers FP16 performance at a 1:1 ratio with FP32 (10.71 TFLOPS), while the T600 Mobile’s FP16 performance is a 2:1 ratio (5.053 TFLOPS). The T600 Mobile belongs to the Quadro Turing-M generation, while the CMP 70HX is listed under the Mining GPUs generation. The T600 Mobile’s predecessor is the Quadro Pascal-M, and its successor is the Ampere-MW, while the CMP 70HX has no listed predecessor or successor. These are not just different cards; they are products from different eras and for different purposes, with the CMP 70HX representing a far more advanced and complex silicon design.
