AMD Radeon 820M vs NVIDIA RTX 5000 Ada Generation Comparison

# AMD Radeon 820M vs NVIDIA RTX 5000 Ada Generation

The AMD Radeon 820M and NVIDIA RTX 5000 Ada Generation sit at opposite ends of the GPU spectrum. The Radeon 820M is an integrated graphics processor built for portable devices, while the RTX 5000 Ada is a dual-slot workstation-class accelerator. The database contains no direct head-to-head benchmark comparisons between these two parts, but the recorded data for the RTX 5000 Ada shows an average benchmark score of 184,664, placing it in the 98th percentile of all GPUs. The Radeon 820M has an average benchmark score of 0 and sits at the 50th percentile, which reflects the absence of recorded benchmark entries rather than an actual performance measurement. The architectural and specification differences between these two products are substantial, and the data indicates they serve fundamentally different roles.

Where Each One Wins

The Radeon 820M occupies the integrated graphics segment, designed for systems where discrete graphics are not present. Its specifications confirm this positioning: it uses system-shared memory, has a 15 W TDP, and connects via PCIe 4.0 x8. The 820M has no power connectors and no slot width because it is an IGP, meaning it resides on the processor package itself. The RTX 5000 Ada Generation, by contrast, is a dedicated workstation card with a 250 W TDP, a dual-slot cooler, and a single 16-pin power connector. The RTX 5000 Ada also lists a suggested PSU of 600 W, a figure that does not appear for the 820M because integrated graphics do not require a dedicated power supply recommendation.

In terms of compute capability, the RTX 5000 Ada delivers 65.28 TFLOPS of FP32 performance, while the 820M provides 716.8 GFLOPS. That difference is roughly 91 times in favor of the RTX 5000 Ada, a gap that reflects their respective targets. The RTX 5000 Ada also offers 32 GB of dedicated GDDR6 memory with a 256-bit bus and 576.0 GB/s bandwidth, whereas the 820M relies on system memory with bandwidth described as system dependent. The RTX 5000 Ada clearly wins for memory-intensive professional workloads, while the 820M exists to provide basic graphics capability in portable devices without the power and space requirements of a discrete card.

Architecture Differences

The two GPUs use entirely different architectures from different manufacturers. The Radeon 820M is built on RDNA 3.5, uses the Krackan Point 2 chip, and belongs to the Navi III IGP (Strix Point Mobile) generation. It is manufactured on a 4 nm process at TSMC. The RTX 5000 Ada Generation uses the Ada Lovelace architecture, employs the AD102 chip, and belongs to the Workstation Ada generation. It is manufactured on a 5 nm process, also at TSMC. The transistor counts differ enormously: the RTX 5000 Ada contains 76,300 million transistors on a 609 mm² die, with a transistor density of 125.3M per mm². The 820M's transistor count and die size are listed as unknown in the database, which is typical for integrated graphics that share a die with the CPU.

The execution resources tell a similar story. The Radeon 820M has 128 shading units, 8 texture mapping units, 4 raster operation units, and 2 ray tracing cores. The RTX 5000 Ada has 12,800 shading units, 400 TMUs, 176 ROPs, 100 ray tracing cores, and 400 tensor cores. The RTX 5000 Ada also has dedicated tensor cores, which the 820M lacks entirely. Clock speeds differ as well: the 820M has a base clock of 400 MHz and a boost clock of 2800 MHz, while the RTX 5000 Ada has a base clock of 1155 MHz and a boost clock of 2550 MHz. The 820M boosts higher, but with far fewer execution units, so its aggregate throughput remains much lower.

Pixel and texture rates reflect the resource disparity. The 820M achieves 11.20 GPixel/s and 22.40 GTexel/s. The RTX 5000 Ada reaches 448.8 GPixel/s and 1,020.0 GTexel/s. The RTX 5000 Ada is roughly 40 times faster in pixel throughput and over 45 times faster in texture throughput. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature support is comparable. The RTX 5000 Ada lists four DisplayPort 1.4a outputs, while the 820M's display outputs are described as portable device dependent, which reflects its integrated nature.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Radeon 820M and the RTX 5000 Ada Generation. The winsA and winsB fields are both zero, and the headToHeadBenchmarks array is empty. The only benchmark data available belongs to the RTX 5000 Ada: it scored 175,286 in Geekbench OpenCL and 194,041 in Geekbench Vulkan. These two results average to 184,664, which is the recorded average benchmark score. The nearest rivals for the RTX 5000 Ada provide context for interpreting these numbers. The NVIDIA A100 SXM4 80 GB scored 183,725, which is 0.5% lower than the RTX 5000 Ada. The NVIDIA A100 SXM4 40 GB scored 187,147, which is 1.3% higher. The NVIDIA RTX PRO 5000 Blackwell scored 182,109, which is 1.4% lower. The NVIDIA GeForce RTX 4090 D scored 178,050, which is 3.7% lower.

This tells a clear story: the RTX 5000 Ada Generation performs at the upper tier of workstation and data center GPUs, within a few percentage points of the A100 variants and ahead of the RTX 4090 D by 3.7%. The Radeon 820M has no recorded benchmarks, so no quantitative comparison exists between the two in the database. The 820M's 50th percentile placement against all GPUs likely reflects its integrated-class positioning, but without benchmark entries, this is not a measured performance figure. The data simply does not support a numerical head-to-head comparison, and any attempt to construct one would require assumptions beyond the recorded facts.

The Verdict

The recorded data indicates that the RTX 5000 Ada Generation is a high-performance workstation GPU, while the Radeon 820M is an integrated graphics solution for portable devices. The RTX 5000 Ada delivers 65.28 TFLOPS of FP32 compute, 32 GB of GDDR6 memory, and 576.0 GB/s of bandwidth, placing it in the 98th percentile of all GPUs. Its nearest rivals include the A100 SXM4 variants and the RTX PRO 5000 Blackwell, all of which score within a narrow range around 184,000 in average benchmark score. The Radeon 820M offers 716.8 GFLOPS of FP32 compute, system-shared memory, and a 15 W TDP, which aligns with its role as an IGP in mobile systems.

For users selecting a GPU strictly from the database, the RTX 5000 Ada Generation is the clear choice for compute-heavy workstation workloads. Its benchmark scores, memory capacity, and throughput rates position it as a professional-grade accelerator. The Radeon 820M is appropriate only for systems where integrated graphics are the intended solution, such as thin-and-light laptops where a 250 W discrete card is not feasible. The 820M has no recorded benchmark scores, so its performance cannot be quantified from the database. The RTX 5000 Ada, by contrast, has two recorded benchmark entries and sits among the top 2% of all GPUs. The decision between these two products is effectively a decision between a dedicated workstation accelerator and an integrated graphics processor, and the data supports the RTX 5000 Ada for any workload that demands substantial compute resources.
