Architecture Differences

The Radeon 820M is an integrated GPU using the RDNA 3.5 architecture, fabricated on a 4 nm process at TSMC. It belongs to the Navi III IGP generation and uses the Krackan Point 2 chip. The RTX 5090 D V2 is a discrete card using the Blackwell 2.0 architecture, built on a 5 nm process, also at TSMC, with the GB202 chip. The transistor counts differ enormously: the Radeon 820M's count is unknown, while the RTX 5090 D V2 packs 92,200 million transistors on a 750 mm² die, with a transistor density of 122.9M per mm².

The compute resources are in completely different classes. The Radeon 820M has 128 shading units, 8 texture mapping units, 4 ROPs, and 2 ray tracing cores. The RTX 5090 D V2 has 21760 shading units, 680 TMUs, 176 ROPs, 170 ray tracing cores, and 680 tensor cores. The Radeon 820M has no tensor cores listed, which is expected for an IGP. Clock behavior also differs: the Radeon 820M has a 400 MHz base clock boosting to 2800 MHz, while the RTX 5090 D V2 runs at a 2017 MHz base and 2407 MHz boost. The NVIDIA card's memory clock is 1750 MHz with 28 Gbps effective speed, whereas the AMD IGP uses system shared memory.

The process node advantage goes to the Radeon 820M at 4 nm versus 5 nm, but that does not compensate for the scale difference in execution resources. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The bus interfaces differ: PCIe 4.0 x8 for the Radeon 820M and PCIe 5.0 x16 for the RTX 5090 D V2. The RTX 5090 D V2 has a successor listed as GeForce 60, while the Radeon 820M has no successor. The NVIDIA card's predecessor is GeForce 40; the Radeon 820M's predecessor is Navi II IGP.

Head-to-Head Benchmarks

The database records no head-to-head benchmark entries between these two products. However, the RTX 5090 D V2's single recorded benchmark, 3DMark Steel Nomad DX12, yields a score of 16504. Its nearest rivals in the database are all close: the NVIDIA T400 scores 16508 (0% delta), the AMD Radeon PRO W7500 scores 16415 (0.5% delta), the NVIDIA RTX PRO 6000 Blackwell scores 16408 (0.6% delta), and the AMD Radeon RX 5700 XT scores 16361 (0.9% delta). These margins are small, indicating that in this specific test the RTX 5090 D V2 performs nearly identically to those four cards, despite the massive architectural differences among them.

The Radeon 820M has no benchmark scores in the database, so direct numerical comparison is impossible. What the data does show is the percentile placement: the Radeon 820M sits at the 50th percentile of all GPUs, while the RTX 5090 D V2 sits at the 59th percentile. That nine-point percentile gap is meaningful, but without a common benchmark score for the Radeon 820M, the measured difference in absolute performance cannot be quantified from recorded results.

The pixel and texture rates illustrate the scale gap. The Radeon 820M delivers 11.20 GPixel/s and 22.40 GTexel/s. The RTX 5090 D V2 delivers 423.6 GPixel/s and 1,636.8 GTexel/s. The floating-point throughput shows a similar pattern: 716.8 GFLOPS FP32 for the Radeon 820M versus 104.8 TFLOPS FP32 for the RTX 5090 D V2. Both products list FP16 at a 1:1 ratio with FP32. These are theoretical peak rates, not application benchmarks, but they align with the percentile difference recorded in the database.

The Verdict

The recorded data places these products at opposite ends of the GPU spectrum. The Radeon 820M is an active, 15 W integrated solution with no dedicated memory, no power connectors, and no recorded benchmark scores. The RTX 5090 D V2 is an active, 575 W discrete card with 24 GB of GDDR7, a 950 W suggested power supply, and a recorded 3DMark Steel Nomad DX12 score of 16504. Its percentile ranking of 59 versus the Radeon 820M's 50 reflects the performance gulf, though the lack of a shared benchmark result for the Radeon 820M prevents a precise percentage comparison.

The RTX 5090 D V2's nearest rivals in the database are all within 0.9% of its score, which suggests that in the Steel Nomad DX12 workload, the card is effectively tied with the NVIDIA T400, AMD Radeon PRO W7500, NVIDIA RTX PRO 6000 Blackwell, and AMD Radeon RX 5700 XT. This is notable because those cards span workstation and consumer segments. The Radeon 820M, by contrast, has no recorded scores and no rival list, so its position in the database rests entirely on its hardware specifications and percentile placement.

For any workload that requires sustained rendering throughput, large memory capacity, or ray tracing, the RTX 5090 D V2 is the only option with recorded data to support that role. The Radeon 820M, with 128 shading units and system shared memory, appears suited to lightweight graphics tasks in a portable device, as its display outputs are listed as portable device dependent. The launch MSRP of the RTX 5090 D V2 is 2,299 USD.

Specification Differences

The two products differ in nearly every measurable field. The Radeon 820M uses the RDNA 3.5 architecture on a 4 nm process, while the RTX 5090 D V2 uses Blackwell 2.0 on a 5 nm process. The Radeon 820M's transistor count and die size are unknown; the RTX 5090 D V2 has 92,200 million transistors on a 750 mm² die with a density of 122.9M per mm².

Clock speeds: the Radeon 820M has a 400 MHz base and 2800 MHz boost, with system shared memory. The RTX 5090 D V2 has a 2017 MHz base and 2407 MHz boost, with a 1750 MHz memory clock at 28 Gbps effective. Memory capacity is system shared versus 24 GB of GDDR7. Bus width is system shared versus 384 bit. Bandwidth is system dependent versus 1.34 TB/s.

Compute units: the Radeon 820M has 128 shading units, 8 TMUs, 4 ROPs, and 2 RT cores. The RTX 5090 D V2 has 21760 shading units, 680 TMUs, 176 ROPs, 170 RT cores, and 680 tensor cores. The Radeon 820M has no tensor cores listed. Pixel rate: 11.20 GPixel/s versus 423.6 GPixel/s. Texture rate: 22.40 GTexel/s versus 1,636.8 GTexel/s. FP32: 716.8 GFLOPS versus 104.8 TFLOPS. FP16 is 1:1 for both.

Power and physical attributes: the Radeon 820M is 15 W, IGP slot width, no power connectors, and no suggested PSU. The RTX 5090 D V2 is 575 W, dual-slot, 1x 16-pin power connector, and a suggested PSU of 950 W. The Radeon 820M uses PCIe 4.0 x8; the RTX 5090 D V2 uses PCIe 5.0 x16. Display outputs: portable device dependent for the Radeon 820M versus 1x HDMI 2.1b and 3x DisplayPort 2.1b for the RTX 5090 D V2. Dimensions: the Radeon 820M has none listed; the RTX 5090 D V2 is 304 mm long, 137 mm high, and 48 mm wide. Release dates: February 28, 2025 versus August 14, 2025.

Where Each One Wins

The RTX 5090 D V2 wins on every recorded performance metric and every hardware specification that affects throughput. Its 24 GB of GDDR7 memory with 1.34 TB/s bandwidth supports large datasets and high-resolution textures. Its 170 ray tracing cores and 680 tensor cores provide dedicated hardware for ray-traced workloads and AI-accelerated tasks. The 104.8 TFLOPS FP32 throughput and 1,636.8 GTexel/s texture rate place it far above the Radeon 820M's 716.8 GFLOPS and 22.40 GTexel/s. The 423.6 GPixel/s pixel rate versus 11.20 GPixel/s shows a similar advantage in fill-rate-bound scenes. The recorded 3DMark Steel Nomad DX12 score of 16504 confirms real-world measured performance in at least one workload, and the card's nearest rivals in the database all score within 0.9%, so the result is consistent with established hardware in that test.

The Radeon 820M wins on power efficiency and physical integration. Its 15 W TDP, IGP slot width, and lack of power connectors mean it requires no additional power delivery and fits into a portable device. Its 4 nm process node is smaller than the RTX 5090 D V2's 5 nm node, which contributes to its low power draw. The system shared memory design eliminates the need for dedicated VRAM, reducing cost and complexity in a mobile platform. Its 2800 MHz boost clock is higher than the RTX 5090 D V2's 2407 MHz boost, though this does not translate into higher throughput given the massive difference in execution resources. The Radeon 820M also has no suggested PSU requirement, whereas the RTX 5090 D V2 requires a 950 W power supply, a 304 mm card length, and a dual-slot footprint.

For use cases, the RTX 5090 D V2 is the choice for desktop systems that need maximum rendering throughput, large memory capacity, and dedicated ray tracing or tensor hardware. The Radeon 820M is the choice for lightweight, portable devices where power draw, physical space, and integrated operation are the priorities. The data does not support using the Radeon 820M for high-end 3D rendering or gaming, as it has no recorded benchmarks and its hardware specifications are orders of magnitude below the RTX 5090 D V2. Conversely, the RTX 5090 D V2's power and size requirements make it unsuitable for the portable device segment the Radeon 820M targets.
