AMD Radeon RX 560 XT vs NVIDIA CMP 70HX Comparison

Where Each One Wins

The recorded benchmark data splits cleanly between the two workload interfaces. In the OpenCL test, the AMD Radeon RX 560 XT posts 31,387 points against the NVIDIA CMP 70HX’s 25,135 points, a decisive 24.9% advantage. That is the largest margin in the entire comparison, and it gives the AMD card a clear edge in compute-oriented OpenCL workloads. The Vulkan results are much closer: the RX 560 XT scores 36,879, while the CMP 70HX trails at 35,817, a 3% gap. Although the AMD card still wins, the near-tie in Vulkan suggests the NVIDIA chip is far more competitive when the API shifts.

Looking at the broader database context, the RX 560 XT sits at the 79th percentile among all GPUs, with an average benchmark score of 34,133. Its nearest rivals include the NVIDIA RTX A2000 12 GB (34,154, a 0.1% deficit) and the RTX A1000 (34,207, a 0.2% deficit), meaning the RX 560 XT is essentially level with those professional cards. The CMP 70HX, by contrast, sits at the 75th percentile with an average of 30,476. Its closest competitors are the NVIDIA Tesla M60 (30,490, a 0% difference) and the AMD Radeon RX 6700 (30,433, a 0.1% gap). So the RX 560 XT occupies a higher performance tier overall, while the CMP 70HX lands just below it.

The wins tally confirms the story: the RX 560 XT wins both head-to-head benchmarks, while the CMP 70HX wins none. But the magnitude matters. A 24.9% OpenCL lead is a dominant result, whereas the 3% Vulkan margin is within the range where driver optimizations or workload variance could flip the outcome. The data implies the RX 560 XT is the stronger general-purpose compute card, especially for OpenCL-heavy applications, while the CMP 70HX is not far behind in Vulkan-specific tasks.

The Verdict

From the recorded measurements, the AMD Radeon RX 560 XT is the clear choice for anyone prioritizing compute performance across the two tested APIs. It wins both benchmarks, holds a higher average score (34,133 versus 30,476), and sits five percentile points higher in the global database ranking. The 24.9% OpenCL advantage alone is enough to justify selecting the RX 560 XT for OpenCL-centric workloads. Even in Vulkan, where the CMP 70HX comes closest, the RX 560 XT still leads by 3%, so there is no benchmark in this dataset where the NVIDIA card comes out ahead.

The NVIDIA CMP 70HX, however, should not be dismissed. Its Vulkan score of 35,817 is only 1,062 points behind the RX 560 XT’s 36,879, a difference that could be erased by different driver versions or a Vulkan-focused test suite. For users who primarily run Vulkan applications, the CMP 70HX is a viable alternative, especially given its higher raw specifications (more shading units, more memory, more bandwidth). The database also shows the CMP 70HX is essentially tied with the Tesla M60 and only 0.1% behind the RX 6700, placing it in respectable company despite its lower overall score.

The verdict hinges on workload mix. Pure compute with OpenCL: choose the RX 560 XT. Vulkan-centric tasks: either card works, but the RX 560 XT still holds the edge in the recorded data. The CMP 70HX is a mining-specific product with no display outputs, so its use case is narrower by design. For a general-purpose GPU, the RX 560 XT’s dual-API wins and higher percentile make it the safer pick.

Head-to-Head Benchmarks

The Geekbench OpenCL test delivers the most lopsided result. The RX 560 XT scores 31,387, while the CMP 70HX scores 25,135. That is a 6,252-point gap, translating to 24.9% in favor of AMD. To put this in context, the RX 560 XT’s nearest rival in the database, the RTX A2000 12 GB, scores 34,154, so the RX 560 XT is only 2.2% below that card. The CMP 70HX’s 25,135 OpenCL score is far below its own average of 30,476, suggesting this particular test does not favor the NVIDIA architecture. The RX 560 XT, by contrast, scores close to its average (31,387 versus 34,133), indicating OpenCL is a strong workload for the GCN 4.0 design.

The Vulkan test narrows the gap considerably. The RX 560 XT scores 36,879, and the CMP 70HX scores 35,817, a difference of just 1,062 points or 3%. Both cards outperform their OpenCL results in Vulkan, but the CMP 70HX improves more dramatically: from 25,135 to 35,817, a 42.5% jump. The RX 560 XT also improves, from 31,387 to 36,879, a 17.5% gain. This pattern suggests the NVIDIA Ampere architecture responds better to Vulkan’s modern feature set, while the older GCN 4.0 chip is already near its ceiling in both APIs.

The two-test average tells the same story from another angle. The RX 560 XT averages 34,133 across both benchmarks, which is 12% higher than the CMP 70HX’s 30,476. The percentile ranks reinforce this: 79th versus 75th. While the CMP 70HX has more shading units (3,840 versus 1,792) and higher memory bandwidth (608.3 GB/s versus 224.0 GB/s), the recorded benchmarks show that raw specifications do not translate into higher scores in these particular tests. The RX 560 XT’s smaller but better-tuned configuration wins in practice.

Architecture Differences

The two cards come from entirely different design philosophies. The AMD Radeon RX 560 XT uses the Ellesmere chip based on GCN 4.0 architecture, fabricated on a 14 nm process at GlobalFoundries. It packs 5,700 million transistors into a 232 mm² die, yielding a transistor density of 24.6 million per square millimeter. The NVIDIA CMP 70HX uses the GA104 chip based on Ampere architecture, fabricated on an 8 nm process at Samsung. It contains 17,400 million transistors on a 392 mm² die, for a density of 44.4 million per square millimeter. That is a stark contrast: the NVIDIA chip has over three times the transistor count and nearly double the density.

The compute configurations differ just as sharply. The RX 560 XT has 1,792 shading units, 112 texture mapping units, and 32 raster output units. The CMP 70HX has 3,840 shading units, 120 TMUs, and 64 ROPs. The NVIDIA card also includes 30 ray tracing cores and 120 tensor cores, while the RX 560 XT has neither. The FP32 throughput tells the story: the CMP 70HX delivers 10.71 TFLOPS versus the RX 560 XT’s 4.394 TFLOPS, a 2.4x advantage in raw floating-point capability. Both cards have 1:1 FP16 ratios, meaning their half-precision throughput matches their FP32 numbers.

The memory subsystems are also built differently. The RX 560 XT uses 4 GB of GDDR5 on a 256-bit bus, achieving 224.0 GB/s bandwidth. The CMP 70HX uses 8 GB of GDDR6X on the same 256-bit bus, but reaches 608.3 GB/s, nearly three times the bandwidth. Clock speeds favor NVIDIA too: the CMP 70HX runs at 1365 MHz base and 1395 MHz boost, while the RX 560 XT runs at 1074 MHz base and 1226 MHz boost. The pixel and texture rates follow: the CMP 70HX hits 89.28 GPixel/s and 167.4 GTexel/s, versus 39.23 GPixel/s and 137.3 GTexel/s for the AMD card.

API support diverges as well. The RX 560 XT supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The CMP 70HX supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it more forward-looking in both DirectX and Vulkan versions. The RX 560 XT belongs to the Polaris (RX 500) generation with a 2019 release date, while the CMP 70HX is part of NVIDIA’s Mining GPUs generation with no recorded release date. Both are end-of-life products.

Specification Differences

The most obvious divergence is in memory. The RX 560 XT offers 4 GB of GDDR5, while the CMP 70HX offers 8 GB of GDDR6X. Bandwidth follows: 224.0 GB/s versus 608.3 GB/s, a 2.7x difference. The memory clock also differs: 1750 MHz (7 Gbps effective) for AMD versus 1188 MHz (19 Gbps effective) for NVIDIA. The bus width is identical at 256 bits.

Compute unit counts are another major differentiator. The RX 560 XT has 1,792 shading units, 112 TMUs, and 32 ROPs. The CMP 70HX has 3,840 shading units, 120 TMUs, and 64 ROPs. The NVIDIA card also adds 30 ray tracing cores and 120 tensor cores, which the AMD card lacks entirely. FP32 performance is 4.394 TFLOPS versus 10.71 TFLOPS, and FP16 matches at 4.394 TFLOPS and 10.71 TFLOPS respectively.

Clock speeds are lower on the AMD card: 1074 MHz base and 1226 MHz boost versus 1365 MHz base and 1395 MHz boost. Pixel rate is 39.23 GPixel/s versus 89.28 GPixel/s, and texture rate is 137.3 GTexel/s versus 167.4 GTexel/s. The process node differs: 14 nm for AMD versus 8 nm for NVIDIA, with transistor counts of 5,700 million versus 17,400 million, and die sizes of 232 mm² versus 392 mm².

Power and connectivity also separate the pair. The RX 560 XT has a TDP of 150 W with a 1x 6-pin power connector and a suggested PSU of 450 W. The CMP 70HX has no TDP recorded, uses a 1x 12-pin connector, and suggests a 200 W PSU. The bus interface differs dramatically: the RX 560 XT uses PCIe 3.0 x16, while the CMP 70HX uses PCIe 1.0 x4, a legacy interface that may bottleneck data transfer despite the card’s faster memory. Display outputs also differ: the RX 560 XT has 1x HDMI 2.0b and 3x DisplayPort 1.4a, while the CMP 70HX has no outputs at all.

Physical dimensions vary slightly: the RX 560 XT is 241 mm (9.5 inches) long, while the CMP 70HX is 267 mm (10.5 inches) long and 112 mm (4.4 inches) high. Both are dual-slot cards. The RX 560 XT was released on 2019-03-12, while the CMP 70HX has no release date in the database. The RX 560 XT lists its predecessor as Arctic Islands and successor as Vega; the CMP 70HX has neither.
