NVIDIA CMP 70HX vs NVIDIA T1000 Comparison

Head-to-Head Benchmarks

The benchmark data presents an unusual split between the NVIDIA T1000 and the NVIDIA CMP 70HX. In Geekbench OpenCL, the T1000 posts a score of 37,704, while the CMP 70HX trails significantly at 25,135. This is a 50% advantage for the T1000, a decisive margin that places the older Turing-based card well ahead in compute workloads that favor OpenCL execution. The T1000 also outperforms its own nearest rivals in the database, sitting 0.7% below the AMD Radeon RX 5300M and 0.7% below the NVIDIA GeForce GTX TITAN X, while leading the AMD Radeon Pro Duo by 1.2% and the NVIDIA Quadro GV100 by 2.2%. Its average benchmark score of 36,289 places it in the 80th percentile of all GPUs.

The CMP 70HX reverses the outcome in Geekbench Vulkan. It scores 35,817, which edges out the T1000's 34,874 by 2.6%. Although this is a much narrower victory than the T1000's OpenCL win, it demonstrates that the Ampere architecture's Vulkan driver path is competitive. The CMP 70HX's average benchmark score is 30,476, placing it in the 75th percentile. Its nearest rivals include the NVIDIA Tesla M60 at a 0% delta, the AMD Radeon RX 6700 at 0.1% ahead, the AMD Radeon RX 6800 at 1.3% ahead, and the NVIDIA GeForce RTX 3070 Ti at 1.8% ahead. In both of its recorded benchmarks, the CMP 70HX shows a narrower spread between OpenCL and Vulkan performance, while the T1000 exhibits a substantial preference for OpenCL.

The head-to-head data shows one win for each card. The T1000 wins the OpenCL test by a landslide, while the CMP 70HX wins the Vulkan test by a modest margin. These results suggest that the two cards are not simply faster or slower versions of each other; they occupy different performance profiles depending on the API in use. The T1000's OpenCL score is its strongest recorded result, and it is nearly 8% higher than its own Vulkan score. The CMP 70HX, by contrast, records its Vulkan score as its best result, and its OpenCL score is roughly 30% lower than its Vulkan result. This asymmetry is the central takeaway from the head-to-head benchmarks.

Where Each One Wins

The T1000 wins decisively in OpenCL compute tasks. Its 37,704 OpenCL score is 50% higher than the CMP 70HX's OpenCL result, making it the clear choice for workloads that rely on OpenCL acceleration. The T1000 also has a higher average benchmark score overall: 36,289 versus 30,476, a difference of roughly 19%. This places the T1000 in the 80th percentile of all GPUs, compared to the CMP 70HX's 75th percentile. For users prioritizing OpenCL compute performance, the data strongly favors the T1000.

The CMP 70HX wins in Vulkan-based rendering and compute. Its Vulkan score of 35,817 is 2.6% higher than the T1000's Vulkan result. The CMP 70HX also brings a substantially larger memory pool: 8 GB of GDDR6X on a 256-bit bus, delivering 608.3 GB/s of bandwidth, compared to the T1000's 4 GB of GDDR6 on a 128-bit bus with 160.0 GB/s. While memory size and bandwidth are not directly benchmarked in the recorded tests, these specifications are relevant to workloads that exceed 4 GB of frame buffer usage. The CMP 70HX also has far higher raw compute ceilings: 10.71 TFLOPS FP32 versus 2.500 TFLOPS for the T1000, and 10.71 TFLOPS FP16 versus 5.000 TFLOPS for the T1000. The CMP 70HX includes 30 RT cores and 120 tensor cores, while the T1000 has none of either.

The T1000 wins in power efficiency and physical footprint. It draws a 50 W TDP with no power connectors and a suggested PSU of 250 W, while the CMP 70HX requires a 12-pin connector and a 200 W suggested PSU. The T1000 is a single-slot card measuring 156 mm in length and 69 mm in height, while the CMP 70HX is a dual-slot card measuring 267 mm by 112 mm. The T1000 also offers four mini-DisplayPort 1.4a outputs, whereas the CMP 70HX has no display outputs at all. The T1000 connects via PCIe 3.0 x16, while the CMP 70HX uses PCIe 1.0 x4, a severely limited interface.

The Verdict

The data indicates that the NVIDIA T1000 is the better choice for OpenCL-centric compute workloads. Its 50% lead in Geekbench OpenCL over the CMP 70HX is the largest performance gap recorded in the head-to-head tests, and its 80th percentile standing versus the CMP 70HX's 75th percentile reinforces this advantage. The T1000 is also the only one of the two with display outputs, making it suitable for systems that require video output alongside compute. Its single-slot design, 50 W TDP, and lack of external power connectors make it easier to integrate into space-constrained or power-sensitive systems.

The NVIDIA CMP 70HX is the better choice for Vulkan-based workloads and for tasks that require more than 4 GB of memory. Its 2.6% Vulkan win over the T1000, combined with 8 GB of GDDR6X memory and 608.3 GB/s of bandwidth, positions it as the stronger card for large data sets and Vulkan rendering. The CMP 70HX also has far higher FP32 and FP16 throughput, plus hardware ray tracing and tensor cores, which are entirely absent from the T1000. However, its lack of display outputs, dual-slot footprint, and PCIe 1.0 x4 interface limit its use to dedicated compute or mining scenarios.

Users who need a general-purpose GPU with display support and strong OpenCL performance should select the T1000. Users who need maximum memory bandwidth, Vulkan performance, and raw compute throughput in a headless configuration should select the CMP 70HX. The recorded data does not support a single universal winner; the choice depends entirely on the target API and workload.
