AMD Radeon 820M vs NVIDIA GeForce RTX 5070 SUPER Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Radeon 820M and the NVIDIA GeForce RTX 5070 SUPER. The only recorded benchmark score belongs to the RTX 5070 SUPER, which posted 2690 points in the 3dMark Steel Nomad DX12 test. That score places the card at the 18th percentile among all GPUs in the database, meaning roughly 82% of recorded graphics processors score higher. The Radeon 820M has no benchmark entries, so its percentile sits at 50 with an average score of zero, which is a placeholder rather than a measured result.

The RTX 5070 SUPER's nearest rivals in the database are all lower-tier parts. The NVIDIA Quadro K1100M scores 2664, which is 1% behind. The NVIDIA GeForce GT 1030 scores 2662, also 1.1% behind. The Intel Arc Pro B50 matches at 2660, again 1.1% behind, and the NVIDIA GeForce GT 440 trails at 2645, a 1.7% gap. This cluster of results indicates the RTX 5070 SUPER's measured performance is tightly grouped with older entry-level discrete GPUs, despite its modern architecture and high-end specifications. The 2690 score is only 26 points above the closest rival, a margin of roughly one percent, which is within typical run-to-run variance for synthetic benchmarks.

For the Radeon 820M, the absence of recorded benchmarks means no direct numerical comparison is possible. The data shows zero wins for each side in head-to-head testing, confirming that no shared test results exist. Any assessment of relative performance must rely on the specification differences and the architectural characteristics of each part, not on measured scores.

Where Each One Wins

The RTX 5070 SUPER clearly wins in any scenario where raw compute throughput matters. Its FP32 performance is 32.15 TFLOPS, while the Radeon 820M delivers 716.8 GFLOPS. That is a difference of roughly 44 times in favor of the NVIDIA card. The pixel rate tells a similar story: 201.0 GPixel/s for the RTX 5070 SUPER versus 11.20 GPixel/s for the integrated Radeon. Texture rate favors NVIDIA at 502.4 GTexel/s versus 22.40 GTexel/s. These numbers indicate the RTX 5070 SUPER is designed for demanding workloads like high-resolution gaming, 3D rendering, and GPU-accelerated compute tasks, while the Radeon 820M is suited to basic display output and light graphical loads typical of an integrated processor.

The Radeon 820M does have one clear advantage: power consumption. Its TDP is 15 W, while the RTX 5070 SUPER draws 275 W. That is an 18-fold difference. For thin-and-light laptops, ultraportables, or fanless designs, the integrated Radeon is the only practical choice because it requires no additional power connectors and dissipates minimal heat. The RTX 5070 SUPER needs a 16-pin power connector and a dual-slot cooler, making it unsuitable for compact or passively cooled systems.

Memory configuration also separates the two. The RTX 5070 SUPER has 18 GB of dedicated GDDR7 memory on a 192-bit bus with 672.0 GB/s of bandwidth. The Radeon 820M uses system shared memory, with bandwidth listed as system dependent. This means the integrated GPU's performance scales with the host system's RAM speed and channel configuration, which is typically far slower than dedicated VRAM. For large textures, high resolutions, or data-intensive workloads, the NVIDIA card has a decisive edge.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The Radeon 820M uses RDNA 3.5, built on a 4 nm process at TSMC. It is part of the Navi III IGP generation, specifically the Krackan Point 2 chip, which targets mobile integrated graphics. The RTX 5070 SUPER uses Blackwell 2.0, built on a 5 nm process, also at TSMC, and is part of the GeForce 50 series with the GB205 chip.

The RTX 5070 SUPER has 31,100 million transistors on a 263 mm² die, yielding a transistor density of 118.3 million per square millimeter. The Radeon 820M's transistor count and die size are listed as unknown, so no direct density comparison is possible. Notably, the RTX 5070 SUPER uses a larger process node (5 nm versus 4 nm), yet packs far more transistors, which reflects its much larger physical die and higher complexity.

Shader resources differ massively. The Radeon 820M has 128 shading units, 8 texture mapping units, 4 render output units, and 2 ray tracing cores. The RTX 5070 SUPER has 6400 shading units, 200 TMUs, 80 ROPs, 50 RT cores, and 200 tensor cores. The NVIDIA card has 50 times more shading units and 25 times more RT cores. Tensor cores exist only on the NVIDIA side, enabling AI acceleration features like DLSS and other neural network workloads that the Radeon cannot perform.

Clock behavior also differs. The Radeon 820M has a base clock of 400 MHz and a boost of 2800 MHz, a wide range that allows it to idle at very low power and ramp up when needed. The RTX 5070 SUPER has a base of 2325 MHz and a boost of 2512 MHz, a much narrower range, reflecting a design that runs at consistently high clocks under load. The memory clock for the Radeon is system shared, while the RTX 5070 SUPER runs at 1750 MHz with 28 Gbps effective data rate.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature support is identical. The Radeon 820M uses a PCIe 4.0 x8 interface, while the RTX 5070 SUPER uses PCIe 5.0 x16, providing four times the lanes and a newer generation for higher bandwidth to the host system.

The Verdict

The data presents two completely different products. The AMD Radeon 820M is an integrated graphics solution built for low power consumption, with a 15 W TDP, no dedicated memory, and modest compute resources. Its 128 shading units and 716.8 GFLOPS FP32 performance suit basic desktop tasks, video playback, and light 2D workloads. The 4 nm process node and 2800 MHz boost clock show efficiency-focused engineering, but the lack of any benchmark scores in the database means its real-world performance is unverified.

The NVIDIA GeForce RTX 5070 SUPER is a high-end discrete card with 6400 shading units, 50 RT cores, 200 tensor cores, and 18 GB of GDDR7 memory. Its 672.0 GB/s bandwidth and 32.15 TFLOPS FP32 make it capable of heavy gaming, rendering, and AI workloads. However, its measured benchmark score of 2690 places it at the 18th percentile, which is surprisingly low for such a well-equipped card. The nearest rivals are all older or lower-tier models with scores within 1.7%, suggesting the recorded test may not reflect the card's full potential, or that the Steel Nomad workload does not favor this architecture.

The choice comes down to system type. For a portable, fanless, or power-constrained device, the Radeon 820M is the only viable option. For a desktop or large laptop with adequate cooling and a 275 W power budget, the RTX 5070 SUPER offers vastly higher performance, but the benchmark data shows it competing with much older parts in this specific test. The Radeon 820M has no measured wins, and the RTX 5070 SUPER has no measured wins either, since no shared benchmarks exist. Buyers should treat the RTX 5070 SUPER's specifications as the primary indicator of its capability, while the Radeon 820M should be judged as a basic integrated solution with no discrete-level expectations.
