AMD Radeon 820M vs NVIDIA RTX 2000 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The database does not contain any recorded head-to-head benchmark scores for the AMD Radeon 820M versus the NVIDIA RTX 2000 Mobile Ada Generation. Both entries show an average benchmark score of zero, with no individual benchmark entries captured and no wins recorded for either side in the head-to-head table. This absence of data means a direct numerical comparison of application performance, gaming frame rates, or compute workloads cannot be constructed from the recorded information.

What can be established from the database is the theoretical peak throughput difference between the two parts. The AMD Radeon 820M delivers 716.8 GFLOPS of FP32 compute, while the NVIDIA RTX 2000 Mobile Ada Generation delivers 12.99 TFLOPS. That puts the NVIDIA part at roughly 18 times the raw single-precision throughput of the AMD part, a magnitude of difference that would dominate any real-world workload that scales with shader compute. Similarly, the pixel rate of the Radeon 820M is 11.20 GPixel/s against 101.5 GPixel/s for the RTX 2000 Mobile Ada, an approximate 9-fold gap. The texture rate shows 22.40 GTexel/s versus 203.0 GTexel/s, again a large margin in favor of the NVIDIA solution.

Both parts share the same DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 API support, so feature-level compatibility at the API layer does not differentiate them. The AMD part uses RDNA 3.5 architecture on a 4 nm TSMC process, while the NVIDIA part uses Ada Lovelace on a 5 nm TSMC process. The process node difference favors AMD in lithographic density, but the NVIDIA chip packs far more execution resources. The RTX 2000 Mobile Ada integrates 18,900 million transistors on a 159 mm² die, with a transistor density of 118.9M per mm². The AMD part's transistor count and die size are listed as unknown, so no density comparison can be made.

The power envelope also separates these products. The Radeon 820M is rated at 15 W TDP, while the RTX 2000 Mobile Ada is rated at 50 W TDP. The NVIDIA part consumes more than three times the power budget, which aligns with its substantially higher peak throughput figures. Both are integrated-class parts with no power connectors and portable-device-dependent display outputs, but the bus interface differs: the AMD part uses PCIe 4.0 x8, and the NVIDIA part uses PCIe 4.0 x16.

Architecture Differences

The AMD Radeon 820M is built on the RDNA 3.5 architecture, specifically from the Navi III IGP generation, with a chip designated as Krackan Point 2. The process node is 4 nm at TSMC. The NVIDIA RTX 2000 Mobile Ada Generation uses the Ada Lovelace architecture on a 5 nm TSMC process, with an AD107 chip. The AMD part belongs to a mobile integrated graphics lineage, while the NVIDIA part sits in the GeForce 20-series mobile workstation segment.

Execution resource counts differ sharply. The Radeon 820M has 128 shading units, 8 texture mapping units, and 4 raster operation pipelines. The RTX 2000 Mobile Ada has 3072 shading units, 96 TMUs, and 48 ROPs. That is 24 times the shading units, 12 times the TMUs, and 12 times the ROPs. The RTX 2000 Mobile Ada also includes 24 ray tracing cores and 96 tensor cores, while the Radeon 820M lists 2 ray tracing cores and no tensor cores. The tensor core presence gives the NVIDIA part a dedicated path for AI and deep learning workloads that the AMD part lacks entirely.

Clock behavior also differs. The Radeon 820M has a base clock of 400 MHz and a boost clock of 2800 MHz. The RTX 2000 Mobile Ada has a base clock of 1635 MHz and a boost clock of 2115 MHz. The AMD part has a much wider clock range, with a low idle base and a high boost, while the NVIDIA part operates in a narrower, higher band. The AMD boost clock is 685 MHz higher than the NVIDIA boost clock, but the NVIDIA part's massive shader count overwhelms that clock advantage in aggregate throughput.

Memory architecture is fundamentally different. The Radeon 820M uses system-shared memory with a system-dependent bandwidth, meaning its performance is tied to the host platform's memory configuration. The RTX 2000 Mobile Ada has 8 GB of dedicated GDDR6 memory on a 128-bit bus, with a fixed bandwidth of 256.0 GB/s. The memory clock for the NVIDIA part is 2000 MHz with 16 Gbps effective transfer rate. The AMD part has no dedicated VRAM, no fixed bus width, and no guaranteed bandwidth figure, which makes its memory performance platform-dependent rather than a fixed specification.

The production status for both is Active. The Radeon 820M released on 2025-02-28, while the RTX 2000 Mobile Ada released on 2023-03-20, so the AMD part is newer by a substantial margin. The AMD predecessor is listed as Navi II IGP, and the NVIDIA predecessor is Ampere-MW with a successor of Blackwell-MW.

Where Each One Wins

The recorded data does not include any benchmark wins for either product, so the win split cannot be derived from direct measurements. Instead, the specification deltas indicate where each part would hold an advantage based on architectural capability.

The AMD Radeon 820M wins on process node efficiency. Its 4 nm TSMC process is a smaller lithography than the 5 nm process used by the NVIDIA part, which typically enables lower leakage and better power efficiency at equivalent transistor counts. The Radeon 820M also has a far lower TDP at 15 W versus 50 W, making it suitable for ultra-portable, fanless or low-power designs. Its system-shared memory model simplifies board design and reduces cost, and its PCIe 4.0 x8 interface is sufficient for an integrated GPU with no dedicated VRAM. The 2800 MHz boost clock is the highest clock figure in either specification list, which could benefit lightly-threaded workloads that respond to clock speed rather than raw parallelism.

The NVIDIA RTX 2000 Mobile Ada Generation wins on nearly every raw performance metric in the database. Its FP32 throughput of 12.99 TFLOPS dwarfs the 716.8 GFLOPS of the AMD part. Its pixel rate of 101.5 GPixel/s is 9 times higher, and its texture rate of 203.0 GTexel/s is 9 times higher. The dedicated 8 GB GDDR6 memory with 256.0 GB/s bandwidth provides predictable, high-throughput memory access that the system-shared AMD configuration cannot guarantee. The 3072 shading units, 96 TMUs, and 48 ROPs provide massive parallel execution capacity. The 24 ray tracing cores and 96 tensor cores add hardware acceleration for ray-traced graphics and AI inference that the AMD part cannot match with its 2 ray tracing cores and no tensor cores.

For workloads that are memory-bandwidth sensitive, the NVIDIA part has a fixed 256.0 GB/s, while the AMD part's bandwidth is system-dependent, meaning its actual performance could vary significantly between platforms. For workloads that are compute-bound, the NVIDIA part's 12.99 TFLOPS is the dominant figure. For workloads that are power-constrained, such as thin-and-light laptops with small batteries, the AMD part's 15 W TDP is the more favorable specification.
