AMD Radeon 820M vs NVIDIA GeForce RTX 5080 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 5080 SUPER. The two products occupy entirely separate segments, and the recorded data reflects that separation. The Radeon 820M has no benchmark scores listed in its entry, while the RTX 5080 SUPER has a single recorded result: a 3DMark Steel Nomad DX12 score of 3075.

That single score places the RTX 5080 SUPER at the 19th percentile among all GPUs in the database. In practical terms, this means the RTX 5080 SUPER outperforms approximately 81% of all recorded graphics cards. The nearest rivals in the database clarify its position. The NVIDIA Quadro P1000 scores 3163, which is 2.8% higher than the RTX 5080 SUPER. The Intel Arc Pro B60 scores 3182, 3.4% higher. On the lower side, the NVIDIA GeForce 820A scores 2983, which is 3.1% below the RTX 5080 SUPER, and the NVIDIA GeForce GTX 860M scores 2967, 3.6% below.

The benchmark data shows a tightly clustered group around the RTX 5080 SUPER's score. The spread from the lowest rival (GTX 860M at 2967) to the highest (Arc Pro B60 at 3182) is only 215 points, or roughly 7%. Within that narrow band, the RTX 5080 SUPER sits near the middle, slightly closer to the lower-scoring rivals than to the higher-scoring ones.

The Radeon 820M, by contrast, has no recorded benchmark data. Its percentile rank of 50 indicates a median position among all GPUs, but this percentile is not derived from any actual test scores. The absence of benchmark entries means the database cannot produce a direct numerical comparison between the two cards. Any head-to-head analysis must rely on architectural specifications and raw compute capabilities rather than measured performance.

Where Each One Wins

The RTX 5080 SUPER wins decisively across every measurable compute category. Its FP32 throughput is 56.28 TFLOPS, compared to the Radeon 820M's 716.8 GFLOPS. This is a difference of roughly two orders of magnitude. The RTX 5080 SUPER processes 10752 shading units, while the Radeon 820M has 128. Texture mapping units number 336 versus 8, and render output units number 112 versus 4.

Memory bandwidth shows a similar gap. The RTX 5080 SUPER uses 24 GB of GDDR7 memory on a 256-bit bus, delivering 1.02 TB/s. The Radeon 820M uses system shared memory with bandwidth described as system dependent. This means the integrated GPU's memory performance varies with the host platform, whereas the RTX 5080 SUPER has dedicated, fixed bandwidth.

Ray tracing resources differ substantially. The RTX 5080 SUPER has 84 RT cores, while the Radeon 820M has 2. Tensor cores are present on the RTX 5080 SUPER at 336 units; the Radeon 820M has none listed. For rasterization throughput, the RTX 5080 SUPER achieves 293.1 GPixel/s and 879.3 GTexel/s, versus 11.20 GPixel/s and 22.40 GTexel/s for the Radeon 820M.

The Radeon 820M wins in power efficiency. Its TDP is 15 W, while the RTX 5080 SUPER draws 415 W. This is a 27.7x difference in thermal design power. The Radeon 820M requires no power connectors and fits as an IGP, making it suitable for compact, low-power systems. The RTX 5080 SUPER is a dual-slot card measuring 304 mm in length, 137 mm in height, and 40 mm in width, requiring a single 16-pin power connector.

The Verdict

The recorded data supports only one conclusion for raw performance: the RTX 5080 SUPER is in a different performance class entirely. Its FP32 compute is 78.5x higher than the Radeon 820M. Its pixel rate is 26.2x higher, and its texture rate is 39.3x higher. The RTX 5080 SUPER has 84x more shading units, 42x more TMUs, and 28x more ROPs.

The Radeon 820M, however, is not designed to compete with the RTX 5080 SUPER. Its 15 W TDP, system shared memory, and IGP form factor indicate a target platform of thin-and-light laptops or low-power mini PCs. The RTX 5080 SUPER, with its 415 W TDP and 16-pin connector, targets high-end desktop gaming and workstation workloads.

For users running the 3DMark Steel Nomad DX12 benchmark, the RTX 5080 SUPER's score of 3075 places it within 2.8% of the Quadro P1000 and 3.4% of the Arc Pro B60, while leading the GeForce 820A by 3.1% and the GTX 860M by 3.6%. This indicates balanced performance near the top of its immediate peer group, though not a dominant leader.

The Radeon 820M has no benchmark scores to compare. Its percentile rank of 50 in the database reflects no measured data, so any judgment about its real-world performance must rely on its specifications. The architecture shows 128 shading units, 8 TMUs, and 4 ROPs, with support for DirectX 12 Ultimate and ray tracing through 2 RT cores. This is entry-level integrated graphics capability.

The choice between these two products depends entirely on the system context. The Radeon 820M suits portable, low-power designs where the 15 W TDP and IGP form factor are mandatory. The RTX 5080 SUPER suits desktop systems with 415 W power headroom and physical space for a 304 mm dual-slot card. The data does not suggest any scenario where the Radeon 820M would outperform the RTX 5080 SUPER in compute or graphics workloads.

Architecture Differences

The Radeon 820M is built on RDNA 3.5 and manufactured on a 4 nm process at TSMC. Its chip is the Krackan Point 2, part of the Navi III IGP generation for Strix Point Mobile. The RTX 5080 SUPER uses Blackwell 2.0 architecture on a 5 nm process, also at TSMC, with the GB203 chip from the GeForce 50-series.

The physical scale differs enormously. The RTX 5080 SUPER contains 45,600 million transistors on a 378 mm² die, yielding a transistor density of 120.6M per mm². The Radeon 820M's transistor count and die size are not recorded in the database.

Clock speeds show distinct strategies. The Radeon 820M has a base clock of 400 MHz and a boost clock of 2800 MHz. The RTX 5080 SUPER has a base clock of 2295 MHz and a boost clock of 2617 MHz. The Radeon 820M's wide boost range reflects power-constrained mobile operation, while the RTX 5080 SUPER runs closer to its base frequency under load.

Compute resources diverge sharply. The Radeon 820M has 128 shading units, 8 TMUs, and 4 ROPs. The RTX 5080 SUPER has 10752 shading units, 336 TMUs, and 112 ROPs. Ray tracing cores number 2 on the Radeon 820M versus 84 on the RTX 5080 SUPER. Tensor cores appear only on the RTX 5080 SUPER, with 336 units.

Memory architecture separates the two completely. The Radeon 820M relies on system shared memory with no dedicated VRAM, no fixed bus width, and bandwidth dependent on the host system. The RTX 5080 SUPER has 24 GB of GDDR7 on a 256-bit bus with 1.02 TB/s of bandwidth. Memory speed for the RTX 5080 SUPER is 2000 MHz with 32 Gbps effective transfer.

Interface and power delivery differ by design. The Radeon 820M uses PCIe 4.0 x8 and has no power connectors, reflecting its IGP status. The RTX 5080 SUPER uses PCIe 5.0 x16 with a single 16-pin connector. Display outputs also diverge: the Radeon 820M's outputs are portable device dependent, while the RTX 5080 SUPER offers 1x HDMI 2.1b and 3x DisplayPort 2.1b.

Both products support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Radeon 820M's FP16 throughput equals its FP32 at 716.8 GFLOPS (1:1), and the RTX 5080 SUPER similarly matches FP16 to FP32 at 56.28 TFLOPS (1:1). The RTX 5080 SUPER's launch MSRP is 999 USD.
