Architecture Differences

The AMD Radeon 820M and NVIDIA GeForce RTX 5090 D represent opposite ends of the GPU spectrum, and the architecture data confirms this divide. The Radeon 820M uses the RDNA 3.5 architecture on a 4 nm process from TSMC, built around the Krackan Point 2 chip. It belongs to the Navi III IGP generation for Strix Point Mobile, meaning it is an integrated graphics processor. The RTX 5090 D uses Blackwell 2.0 on a 5 nm process, also from TSMC, with the GB202 chip and belongs to the GeForce 50 series generation.

Transistor counts reveal the scale difference. The RTX 5090 D packs 92,200 million transistors on a 750 mm² die, giving a transistor density of 122.9M per mm². The Radeon 820M lists its transistor count and die size as unknown, which is common for integrated parts where the GPU shares the package with CPU cores.

Shader resources diverge sharply. The Radeon 820M has 128 shading units, 8 texture mapping units, 4 render output units, and 2 ray tracing cores. The RTX 5090 D has 21,760 shading units, 680 TMUs, 176 ROPs, 170 ray tracing cores, and 680 tensor cores. The Radeon 820M has no tensor cores listed. Clock speeds also differ: the Radeon 820M runs at 400 MHz base and 2800 MHz boost, while the RTX 5090 D runs at 2017 MHz base and 2407 MHz boost. The AMD part has a higher boost clock, but the NVIDIA part starts from a much higher base.

Memory architecture is fundamentally different. The Radeon 820M uses system shared memory with a system shared bus width and system dependent bandwidth. The RTX 5090 D has 32 GB of GDDR7 on a 512 bit bus with 1.79 TB/s of bandwidth. The Radeon 820M memory clock is listed as system shared, while the RTX 5090 D memory runs at 1750 MHz with 28 Gbps effective speed.

Power and physical specifications separate these products further. The Radeon 820M has a 15 W TDP, occupies an IGP slot width, requires no power connectors, and uses a PCIe 4.0 x8 interface. The RTX 5090 D has a 575 W TDP, is dual-slot, requires a single 16-pin power connector, suggests a 950 W power supply, and uses PCIe 5.0 x16. The RTX 5090 D measures 304 mm long, 137 mm tall, and 48 mm wide. The Radeon 820M has no recorded dimensions, as its form factor depends on the portable device.

Both GPUs support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ, with the Radeon 820M being portable device dependent and the RTX 5090 D offering 1x HDMI 2.1b and 3x DisplayPort 2.1b.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Radeon 820M and the NVIDIA GeForce RTX 5090 D. The head-to-head results array is empty, and neither product records wins against the other in a matched test. However, individual benchmark data for the RTX 5090 D provides context for its performance level.

The RTX 5090 D delivers a 3DMark Steel Nomad DX12 score of 14,326. Its Geekbench OpenCL score reaches 310,674, and its Geekbench Vulkan score is 376,915. PassMark results show a G3D score of 44,065, a GPU compute score of 28,396, and a G2D score of 1,487. In legacy DirectX tests, the RTX 5090 D scores 434 in DirectX 9, 371 in DirectX 11, 231 in DirectX 10, and 219 in DirectX 12.

The Radeon 820M has no benchmark scores recorded in the database. Its average benchmark score is 0, and its nearest rivals list is empty. This means the database cannot produce a direct numerical comparison between the two products. What can be stated is that the RTX 5090 D achieves an average benchmark score of 77,712 across its recorded tests, while the Radeon 820M has no recorded performance data.

The RTX 5090 D's average score places it in the 92nd percentile of all GPUs in the database. Its nearest rival, the AMD Radeon RX 6650M XT, scores 76,904, which is 1.1% lower. The AMD Radeon RX 6850M XT scores 78,940, which is 1.6% higher than the RTX 5090 D. Two NVIDIA Tesla P100 variants also sit nearby: the 12 GB version scores 79,396 (2.1% higher) and the 16 GB version scores 79,605 (2.4% higher). These small deltas indicate that the RTX 5090 D clusters tightly with high-end mobile and datacenter GPUs from the previous generation.

The Verdict

The data supports a clear split between these two products, though the comparison is limited by the absence of benchmarks for the AMD Radeon 820M. The RTX 5090 D is a discrete, dual-slot add-in card with 32 GB of GDDR7 memory, 21,760 shading units, and a 575 W TDP. The Radeon 820M is an integrated processor with 128 shading units, system shared memory, and a 15 W TDP. The recorded percentile rankings reflect this: the RTX 5090 D sits at the 92nd percentile while the Radeon 820M sits at the 50th percentile.

The RTX 5090 D has an average benchmark score of 77,712, which is the only recorded performance figure between the two. The Radeon 820M has no recorded scores, so its 50th percentile ranking appears to be a default or baseline placement rather than a measured result. Users seeking a GPU for high-end desktop workloads should look at the RTX 5090 D based on its benchmark record. Users seeking an integrated solution for a portable device should consider the Radeon 820M, which consumes 15 W and requires no power connectors, but the database offers no performance measurements to validate its capability.

The launch dates place the RTX 5090 D first (January 29, 2025) and the Radeon 820M second (February 28, 2025). Both are currently active in production. The RTX 5090 D lists a successor (GeForce 60) and a predecessor (GeForce 40), while the Radeon 820M lists only a predecessor (Navi II IGP).

Where Each One Wins

The RTX 5090 D wins in every category where the database records measurable performance. Its average benchmark score of 77,712 is the only recorded performance metric between the two products. Its FP32 compute of 104.8 TFLOPS dwarfs the Radeon 820M's 716.8 GFLOPS. Its texture rate of 1,636.8 GTexel/s compares to 22.40 GTexel/s for the Radeon 820M. Its pixel rate of 423.6 GPixel/s compares to 11.20 GPixel/s. The RTX 5090 D also carries 170 ray tracing cores versus 2, and 680 tensor cores versus none.

The Radeon 820M wins in power efficiency and integration. Its 15 W TDP is dramatically lower than the 575 W TDP of the RTX 5090 D. It requires no power connectors and no separate PSU recommendation, while the RTX 5090 D needs a 16-pin connector and a 950 W power supply. The Radeon 820M occupies IGP slot width, meaning it fits inside a mobile processor package, while the RTX 5090 D is a dual-slot card measuring 304 mm in length. The Radeon 820M also has a higher boost clock (2800 MHz versus 2407 MHz), though its base clock is far lower (400 MHz versus 2017 MHz).

The Radeon 820M uses a 4 nm process compared to the RTX 5090 D's 5 nm process. It uses PCIe 4.0 x8 versus PCIe 5.0 x16. Its memory is system shared and system dependent, which suits portable devices where dedicated memory adds cost and power. The RTX 5090 D's 32 GB of GDDR7 on a 512 bit bus with 1.79 TB/s bandwidth serves high-resolution rendering and large datasets.

The recorded data points to a straightforward split: the RTX 5090 D dominates measured performance, while the Radeon 820M dominates integration efficiency. The RTX 5090 D sits at the 92nd percentile among all GPUs, and the Radeon 820M sits at the 50th percentile. Neither product has a head-to-head benchmark result against the other, so the database cannot confirm how the Radeon 820M would perform in the tests where the RTX 5090 D scores 14,326 in 3DMark Steel Nomad, 310,674 in Geekbench OpenCL, and 376,915 in Geekbench Vulkan.
