AMD Radeon 820M vs NVIDIA RTX PRO 5000 Blackwell Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between the AMD Radeon 820M and the NVIDIA RTX PRO 5000 Blackwell. The database shows zero benchmark wins for either side in a matched comparison. This absence of direct measurements means any comparison must rely on the individual benchmark scores and specification data available for each part.

The NVIDIA RTX PRO 5000 Blackwell has three recorded benchmark results in the database. In the 3DMark Steel Nomad DX12 test, it scores 9579.5 points. Its Geekbench OpenCL score reaches 254116, while the Geekbench Vulkan score climbs to 282631. These three results combine into an average benchmark score of 182109. The AMD Radeon 820M has no recorded benchmark scores in the database, with an average benchmark score of 0. The percentile data reinforces the gap: the RTX PRO 5000 Blackwell sits in the 98th percentile of all GPUs, while the Radeon 820M sits in the 50th percentile.

The nearest rivals for the RTX PRO 5000 Blackwell provide context for its positioning. The NVIDIA A100 SXM4 80 GB posts an average score of 183725, which is 0.9% higher than the RTX PRO 5000 Blackwell. The NVIDIA RTX 5000 Ada Generation scores 184664, 1.4% higher. The NVIDIA GeForce RTX 4090 D trails with 178050, which is 2.3% lower. The NVIDIA A100 SXM4 40 GB leads the group at 187147, 2.7% higher. These deltas show the RTX PRO 5000 Blackwell clustering tightly with high-end workstation and flagship consumer parts, within a narrow band of roughly 3% either direction.

For the Radeon 820M, the database lists no nearest rivals and no benchmark scores. Its 50th percentile ranking places it at the midpoint of all GPUs in the database. The RTX PRO 5000 Blackwell's 98th percentile ranking places it near the very top. The absence of head-to-head data means the comparison cannot quantify the performance margin directly, but the percentile gap of 48 points and the difference in recorded scores establish a clear stratification.

The Verdict

The data indicates two GPUs serving entirely different segments. The RTX PRO 5000 Blackwell delivers workstation-class performance with recorded benchmark scores in the six figures and a 98th percentile standing. The Radeon 820M is an integrated graphics processor with a 50th percentile standing and no recorded benchmark scores in the database.

The RTX PRO 5000 Blackwell shows itself competitive with the A100 SXM4 variants and the RTX 5000 Ada Generation. Its average score of 182109 sits within 2.7% of the A100 SXM4 40 GB, the highest-scoring rival in its nearest rival group. The GeForce RTX 4090 D, a flagship consumer card, falls 2.3% behind it. This positioning confirms the RTX PRO 5000 Blackwell as a top-tier compute and graphics solution.

The Radeon 820M, by contrast, uses system-shared memory and carries a 15 W TDP. It is designed for portable devices where power budgets are constrained. Its 128 shading units and 4 ROPs indicate a basic graphics capability suited to lightweight workloads rather than heavy compute or rendering tasks. The 50th percentile ranking suggests mid-pack performance among all GPUs, but with no benchmark scores recorded, the database cannot confirm its real-world standing.

The verdict from the recorded data is straightforward: the RTX PRO 5000 Blackwell is for professional workloads requiring substantial compute throughput, while the Radeon 820M serves integrated graphics duties in mobile systems. Users needing 48 GB of GDDR7 memory, 66.94 TFLOPS of FP32 performance, and PCIe 5.0 connectivity should look to the NVIDIA part. Users in the market for an IGP with shared memory and a 15 W power envelope will find the AMD option.

Architecture Differences

The AMD Radeon 820M uses the RDNA 3.5 architecture, built on a 4 nm process at TSMC. Its chip is designated Krackan Point 2, and it belongs to the Navi III IGP generation for Strix Point Mobile. The RDNA 3.5 architecture integrates ray tracing cores, with the 820M carrying 2 RT cores. The GPU includes 128 shading units, 8 texture mapping units, and 4 render output units.

The NVIDIA RTX PRO 5000 Blackwell uses the Blackwell 2.0 architecture, built on a 5 nm process at TSMC. Its chip is the GB202, belonging to the Blackwell PRO W (x000) generation. The transistor count reaches 92,200 million, with a die size of 750 mm² and a transistor density of 122.9M per mm². The architecture includes 110 RT cores and 440 tensor cores, the latter enabling AI acceleration workloads. Shading units number 14080, with 440 TMUs and 160 ROPs.

Both architectures support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RDNA 3.5 part delivers FP16 at a 1:1 ratio with FP32, both at 716.8 GFLOPS. The Blackwell part also delivers FP16 at 1:1, reaching 66.94 TFLOPS for both formats. The Radeon 820M's pixel rate is 11.20 GPixel/s with a texture rate of 22.40 GTexel/s. The RTX PRO 5000 Blackwell reaches 380.3 GPixel/s and 1,045.9 GTexel/s.

The process node difference is notable: AMD uses 4 nm while NVIDIA uses 5 nm, both at TSMC. The Radeon 820M's transistor count and die size are listed as unknown in the database, while the NVIDIA part provides full details. The RTX PRO 5000 Blackwell's tensor cores have no equivalent in the Radeon 820M, as the database lists tensor cores as null for the AMD part. This architectural difference points to divergent design goals: the Radeon 820M focuses on efficient integrated graphics, while the RTX PRO 5000 Blackwell targets maximum throughput with dedicated AI hardware.

Specification Differences

The two GPUs differ across nearly every measurable specification. The Radeon 820M has a base clock of 400 MHz and a boost clock of 2800 MHz.

Where Each One Wins

The RTX PRO 5000 Blackwell wins in every recorded performance category. Its average benchmark score of 182109 stands against the Radeon 820M's 0 recorded score. The 98th percentile versus 50th percentile ranking shows a dominant position. The 66.94 TFLOPS FP32 throughput, 1.34 TB/s memory bandwidth, and 48 GB GDDR7 capacity make it suitable for large-scale compute, rendering, and AI workloads. Its 440 tensor cores provide dedicated hardware for neural network operations, and its 110 RT cores handle ray-traced rendering tasks.

The Radeon 820M wins in power efficiency and integration. Its 15 W TDP allows operation without external power connectors, and its IGP slot width means it fits directly on the processor package. The system-shared memory design eliminates the need for dedicated VRAM, reducing cost and complexity in portable systems. Its 4 nm process node is smaller than the NVIDIA part's 5 nm node, which contributes to its low power profile. The PCIe 4.0 x8 interface, while narrower than the NVIDIA's PCIe 5.0 x16, suffices for integrated graphics duties.

The use-case split follows these strengths. The RTX PRO 5000 Blackwell serves workstation environments where compute throughput, large memory pools, and professional display outputs matter. Its 4x DisplayPort 2.1b outputs support multi-monitor professional setups. The Radeon 820M serves portable devices where battery life and thermal constraints take priority. Its portable device dependent display outputs reflect this mobile orientation.

The database shows no overlapping use cases. The Radeon 820M's 128 shading units and 4 ROPs handle basic graphics acceleration, while the RTX PRO 5000 Blackwell's 14080 shading units and 160 ROPs handle professional rendering and simulation. The 716.8 GFLOPS FP32 figure for the AMD part is sufficient for lightweight tasks, while the 66.94 TFLOPS for the NVIDIA part addresses heavy compute demands. The RTX PRO 5000 Blackwell's nearest rivals, including the A100 SXM4 variants and RTX 5000 Ada Generation, all fall within a 2.7% band of its average score, indicating it competes at the top of the database's GPU hierarchy. The Radeon 820M, with no benchmark scores and no nearest rivals, occupies a less defined position that the data cannot further characterize.
