AMD Radeon RX 6700 XT vs NVIDIA CMP 70HX Comparison

Head-to-Head Benchmarks

The benchmark database records only two shared tests between the NVIDIA CMP 70HX and the AMD Radeon RX 6700 XT, and in both cases the AMD card takes a decisive lead. In Geekbench OpenCL, the CMP 70HX scores 25,135, while the RX 6700 XT reaches 44,152. That is a 43.1% deficit for the NVIDIA part, a substantial gap that places the AMD card in a different performance tier for compute workloads. The Vulkan result is even more lopsided. The CMP 70HX posts 35,817, but the RX 6700 XT manages 93,500, a 61.7% advantage. These are not marginal differences, they are category-level separations.

The absence of any shared DirectX tests in the database means the head-to-head picture is built entirely from these two API workloads. Still, the pattern is unambiguous: the RX 6700 XT wins both recorded comparisons, and its average benchmark score of 27,425 confirms it sits in the 72nd percentile of all GPUs. The CMP 70HX, by contrast, has an average of 30,476, good for the 75th percentile, which is curious given its losses in the direct comparisons. The CMP 70HX's average is higher than its own head-to-head scores imply, and it actually lands close to the NVIDIA Tesla M60, which averages 30,490, and the AMD Radeon RX 6700, which averages 30,433, a 0.1% difference from the CMP 70HX average. The AMD Radeon RX 6800 averages 30,095, a 1.3% delta from the CMP 70HX, and the NVIDIA GeForce RTX 3070 Ti averages 29,945, a 1.1% delta from the CMP 70HX, which is 1.8% behind the CMP 70HX. The RX 6700 XT's nearest rival list is a different mix, the NVIDIA GeForce RTX 4070 Mobile averages 27,435, essentially identical to the RX 6700 XT at 0% delta, while the NVIDIA GeForce RTX 3090 averages 27,565, a 0.5% delta below the RX 6700 XT, and the AMD Radeon Pro Vega 20 averages 27,839, a 1.5% delta below the RX 6700 XT, and the AMD RTX PRO 4000 Blackwell averages 27,135, a 1.1% delta above the RX 6700 XT. The RX 6700 XT average sits among these, but its OpenCL and Vulkan wins push it clearly ahead of the CMP 70HX in raw recorded performance.

Where Each One Wins

The AMD Radeon RX 6700 XT wins every use case where the database has direct measurements. Compute workloads, as measured by Geekbench OpenCL, favor the AMD card due to a 43.1% lead. General graphics compute via Vulkan is also a strong AMD domain, with a 61.7% lead over the CMP 70HX. The RX 6700 XT also has a broad set of additional recorded benchmarks that the CMP 70HX lacks entirely, including Passmark DirectX 10, 11, 12, and 9 scores of 124, 173, 77, and 242 respectively, plus Passmark G2D at 951, G3D at 19,786, and GPU compute at 9,336. The RX 6700 XT also records a Geekbench Metal score of 130,896 and a 3DMark Steel Nomad DX12 score of 2,435. None of these can be compared directly to the CMP 70HX since that card has no corresponding entries, but they indicate a much broader validation footprint for the AMD card in the database.

The CMP 70HX has no wins in shared tests, so its advantage must be inferred from its positioning. Its average benchmark score of 30,476 is higher than the RX 6700 XT's 27,425, which suggests that across the full database of tests, the CMP 70HX tends to land closer to higher-performing cards. Its percentile rank of 75 versus 72 for the RX 6700 XT reinforces this. The CMP 70HX's nearest rivals include the AMD Radeon RX 6800, which averages 30,095, and the NVIDIA GeForce RTX 3070 Ti, which averages 29,945, both of which are typically considered upper-midrange parts. The RX 6700 XT's nearest rivals include the NVIDIA GeForce RTX 3090, which averages 27,565, a lower score than the CMP 70HX's average. So the database suggests the CMP 70HX holds its own in aggregate, even if it loses the two head-to-head tests. The RX 6700 XT is the clear winner in every directly comparable workload, but the CMP 70HX has a higher overall average and better percentile placement, which may indicate that its strengths lie outside the tested APIs.

Architecture Differences

The NVIDIA CMP 70HX is built on the GA104 chip with the Ampere architecture, manufactured on an 8 nm process at Samsung, with 17,400 million transistors on a 392 mm² die. The AMD Radeon RX 6700 XT uses the Navi 22 chip with RDNA 2.0, built on a 7 nm process at TSMC, with 17,200 million transistors on a 335 mm² die. The transistor counts are almost identical, 17,400 million versus 17,200 million, but the AMD die is smaller, leading to a higher transistor density of 51.3 million per mm² versus 44.4 million per mm² for the NVIDIA part. The process node difference is one full node, 8 nm versus 7 nm, and the foundries differ as well, Samsung for NVIDIA and TSMC for AMD.

The memory subsystems diverge significantly. The CMP 70HX has 8 GB of GDDR6X on a 256-bit bus, yielding 608.3 GB/s of bandwidth. The RX 6700 XT has 12 GB of GDDR6 on a 192-bit bus, yielding 384.0 GB/s of bandwidth. The NVIDIA card has a clear bandwidth advantage, 608.3 GB/s against 384.0 GB/s, but the AMD card has more capacity, 12 GB versus 8 GB, which matters for larger working sets. The CMP 70HX memory clock is listed as 1188 MHz with 19 Gbps effective, while the RX 6700 XT memory runs at 2000 MHz with 16 Gbps effective. The CMP 70HX uses a 1x 12-pin power connector with a suggested PSU of 200 W, while the RX 6700 XT uses 1x 6-pin plus 1x 8-pin with a suggested PSU of 550 W. The TDP for the CMP 70HX is not recorded, but the RX 6700 XT has a TDP of 230 W.

Compute resources also differ. The CMP 70HX has 3,840 shading units, 120 TMUs, 64 ROPs, 30 RT cores, and 120 tensor cores, with a pixel rate of 89.28 GPixel/s, a texture rate of 167.4 GTexel/s, and FP32 of 10.71 TFLOPS. The RX 6700 XT has 2,560 shading units, 160 TMUs, 64 ROPs, and 40 RT cores, with no tensor cores, a pixel rate of 165.2 GPixel/s, a texture rate of 413.0 GTexel/s, FP32 of 13.21 TFLOPS, and FP16 of 26.43 TFLOPS at a 2:1 ratio. The CMP 70HX has more shading units, but the AMD card has higher clock speeds, with a base of 2321 MHz and boost of 2581 MHz versus the CMP 70HX base of 1365 MHz and boost of 1395 MHz. The RX 6700 XT also has a game clock of 2424 MHz, which the CMP 70HX lacks. The bus interface differs as well, the CMP 70HX uses PCIe 1.0 x4, an unusual and limiting spec, while the RX 6700 XT uses PCIe 4.0 x16. The CMP 70HX has no display outputs, as expected for a mining part, while the RX 6700 XT has 1x HDMI 2.1 and 3x DisplayPort 1.4a. Both cards support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, and both are end-of-life products. Physical dimensions are similar, both are 267 mm long, the CMP 70HX is 112 mm tall, the RX 6700 XT is 110 mm tall and 40 mm wide, and both are dual-slot.

The Verdict

The AMD Radeon RX 6700 XT is the superior card in every directly comparable benchmark in the database. It wins Geekbench OpenCL by 43.1% and Geekbench Vulkan by 61.7%. It has a higher FP32 throughput, 13.21 TFLOPS versus 10.71 TFLOPS, a higher boost clock, 2581 MHz versus 1395 MHz, and more memory capacity, 12 GB versus 8 GB. It also has display outputs, a PCIe 4.0 x16 interface, and a much broader set of recorded benchmarks, including Passmark DirectX 9 through 12, 3DMark Steel Nomad DX12, Geekbench Metal, Passmark G2D, G3D, and GPU compute. Its launch MSRP is 479 USD, stated once for reference. The RX 6700 XT is the clear choice for any workload that involves graphics compute, DirectX, or OpenCL/Vulkan rendering, based on the recorded data, and its higher percentile rank among rivals, which includes the NVIDIA GeForce RTX 3090 at a 0.5% delta below it, reinforces that it fits into a high-performance tier.

The NVIDIA CMP 70HX, meanwhile, records no wins against the RX 6700 XT, lacks display outputs, uses a PCIe 1.0 x4 bus interface, and offers half the memory capacity at 8 GB, though it does have a bandwidth advantage at 608.3 GB/s versus 384.0 GB/s. Its average score of 30,476 is actually higher than the RX 6700 XT, and it sits at the 75th percentile, but this aggregate strength does not translate to victory in any shared test. For a user optimizing for the specific workloads present in the database, the RX 6700 XT is the correct pick. The CMP 70HX may be worth attention only if the broader average score matters more than the direct comparison, but the data shows the AMD card dominates the head-to-head and has a wider range of validated applications. The verdict is straightforward: the AMD Radeon RX 6700 XT wins on recorded performance, feature set, and measured results, while the CMP 70HX remains a niche part with a higher aggregate score but no competitive standing in the tested workloads.
