AMD Radeon RX 6900 XT vs NVIDIA GeForce MX570 A Comparison

Head-to-Head Benchmarks

The benchmark data delivers a decisive victory for the AMD Radeon Radeon RX 6900 XT, with the NVIDIA GeForce MX570 A trailing far behind in every recorded test. In Geekbench OpenCL, the RX 6900 XT scores 187,673 against the MX570 A's 39,780, a 371.8% advantage. The Vulkan results are equally lopsided: 148,525 for the AMD card versus 37,601 for the NVIDIA part, representing a 295% lead. These are not close contests; the RX 6900 XT is in a completely different performance class.

The database's average benchmark score reinforces the gap. The RX 6900 XT posts 50,951 points, landing in the 86th percentile among all GPUs. Its nearest rivals include the NVIDIA CMP 50HX (51,790, only 1.6% higher), the AMD Radeon RX Vega 64 (50,001, 1.9% lower), the NVIDIA GeForce RTX 5070 Ti (49,957, 2% lower), Intel Arc A550M (49,737, 2.4% lower). The MX570 A, by contrast, averages 38,691 points, sitting in the 81st percentile. Its closest competition is the AMD Radeon Pro 580X (38,706, 0% difference), the NVIDIA GeForce RTX 5080 Mobile (38,349, 0.9% higher), the NVIDIA GeForce MX570 (38,299, 1% higher and lower than the AMD Radeon Pro 575X (39,116, 1.1% higher, a 1.1% swing in the other direction).

This positioning matters. The RX 6900 XT sits much closer to the top of the heap, while the MX570 A is embedded in the mid-range territory. In the head-to-head head-to-head, the AMD card wins both available head-to-head tests, wrapping up the comparison with a 2 wins to 0 record. There is no scenario in the recorded data where the MX570 A emerges ahead of the RX 6900 XT in any metric.

Performance scaling is another lens. The RX 3DMark Steel Nomad DX12 score of 4,079, along with Passmark results ranging from 167 in DX10 to 26,732 in G3D and 14,547 in GPU Compute, shows the AMD card's breadth across many workloads. In contrast, the MX570 A lacks comparable recorded scores outside of the two Geekbench tests. The data shows a wide compute performance delta, and the AMD Radeon card's dominance is therefore not a quirk of one API.

Architecture Differences

Underlying architectures could hardly diverge more. The AMD Radeon RX 6900 XT uses the Navi 21 chip on RDNA 2.0 architecture, built on a 7 nm TSMC process. It packs 26,800 million transistors into a 520 mm² die, giving a transistor density of 51.5M / mm². The NVIDIA GeForce MX570 A relies on the GA107SB chip under the Ampere architecture, produced by Samsung on an 8 nm process, with 8,700 million transistors across 200 mm² die size and density 43.5M / mm². AMD's Navi II generation is Navi II (RX 6000 series), while NVIDIA's GeForce MX 5th generation spans the MX570 A.

The compute layout is a stark difference. The RX 6900 XT fields 5,120 shading units, 320 texture mapping units, 128 ROPs, and 80 ray tracing cores, with no tensor cores. Meanwhile, the MX570 A has 2048 shading units, 64 TMUs, 32 ROPs, 16 ray tracing cores, but adds 64 tensor cores. The AMD card's pixel rate sits at 288.0 GPixel/s with texture rate 720.0 GTexel/s, compared to the NVIDIA card's 36.96 GPixel/s pixel rate and 73.92 GTexel/s texture rate. The FP32 throughput is 23.04 TFLOPS for the RX 6900 XT, with FP16 at 46.08 TFLOPS (2:1), while the MX570 A delivers 4.731 TFLOPS FP32 and 4.731 TFLOPS FP16 (1:1).

Clock behavior differs predictably: the RX 6900 XT runs at 1825 MHz base, 2250 MHz boost, and a 2015 MHz game clock, with memory at 2000 MHz (16 Gbps effective). The MX570 A runs at a much lower 832 MHz base and 1155 MHz boost, memory at 1500 MHz (12 Gbps effective). Power envelopes are worlds apart: the RX 6900 XT draws a 300 W TDP with a triple-slot design and 2x 8-pin power connectors, suggesting a 700 W power supply, while the MX570 A is an IGP with no power connectors, rated at just 25 W TDP. The RX 6900 XT supports PCIe 4.0 x16, the MX570 A only PCIe 4.0 x8. Display outputs: the RX 6900 XT provides 1x HDMI 2.1, 2x DisplayPort 1.4a, 1x USB Type-C; the MX570 A is portable device dependent. APIs align closely, both supporting DirectX 12 Ultimate (12_2), OpenGL 4.6 and Vulkan 1.4.

Where Each One Wins

The AMD Radeon RX 6900 XT wins in raw compute, memory capacity, and bandwidth. It holds a 371.8% OpenCL lead and a 295% Vulkan lead over the MX570 A. In the broader database, it sits at the 86th percentile, outscoring its nearest rivals by small margins. For demanding workloads such as high-resolution gaming, content creation, or GPU compute, the data points directly to the RX 6900 XT. Its 16 GB frame buffer is a massive advantage over the MX570 A's 2 GB, and its 512.0 GB/s bandwidth far exceeds the 96.00 GB/s on the NVIDIA part.

The NVIDIA GeForce MX570 A wins in efficiency and form factor. Its 25 W TDP, IGP design, and lack of power connectors make it suited for portable devices. Its FP16 performance at 1:1 ratio matches its FP32 rate, unlike the RX 6900 XT's 2:1 FP16 ratio that halves rate when FP16 is used. The MX570 A also includes 64 tensor cores, which the RX 6900 XT lacks, potentially aiding workloads that rely on tensor core acceleration. Its smaller die and lower power envelope are clear advantages where space and power are constrained.

The RX 6900 XT's nearest rival, the NVIDIA CMP 50HX, is only 1.6% higher in average score, showing the AMD card's strong positioning among its peers. The MX570 A's closest rival, the AMD Radeon Pro 580X, is a 0% delta, indicating the MX570 A sits right at the edge of its performance tier. The RX 6900 XT's wins are decisive and consistent, while the MX570 A's strengths are in areas not directly measured by the benchmark scores: power efficiency, portability, and tensor core support.

The Verdict

Choose the AMD Radeon RX 6900 XT for any task that demands maximum performance. Its 371.8% lead in OpenCL and 295% lead in Vulkan over the MX570 A are the largest deltas in the head-to-head data. The card's 50,951 average benchmark score, 86th percentile ranking, and direct competition with the NVIDIA CMP 50HX and RTX 5070 Ti class parts make it a top-tier choice for desktop builds with sufficient power and space. Its 300 W TDP and triple-slot design require a 700 W power supply and a large chassis, but the payoff is 16 GB of GDDR6 memory and 23.04 TFLOPS of FP32 performance.

Choose the NVIDIA GeForce MX570 A for a portable, low-power configuration. Its 25 W TDP, IGP form factor, and no power connectors make it ideal for thin laptops. The MX570 A's 64 tensor cores and 1:1 FP16 ratio offer capabilities not found on the RX 6900 XT, and its 81st percentile ranking shows it still delivers respectable performance for its class. However, with 2 GB of memory and 4.731 TFLOPS FP32, it cannot compete with the RX 6900 XT in compute-heavy tasks.

The data is unambiguous in performance, but the real decision hinges on the use case. The RX 6900 XT is a high-end desktop anchor, while the MX570 A is a mobile IGP. Each wins in its own domain, and neither crosses over into the other's territory in the benchmark results. The RX 6900 XT's 2 wins out of 2 head-to-head tests seals the performance crown; the MX570 A's advantages in power and portability are qualitative, not quantitative in the database metrics.
