Architecture Differences

The two GPUs represent fundamentally different design philosophies. The AMD Radeon 820M is an integrated graphics processor built on the RDNA 3.5 architecture, fabricated by TSMC on a 4 nm process node. It belongs to the Navi III IGP generation for Strix Point Mobile. The NVIDIA RTX 2000 Max-Q Ada Generation is a discrete-class GPU using the Ada Lovelace architecture on a 5 nm TSMC process, built around the AD107 chip with 18,900 million transistors on a 159 mm² die size.

The transistor density metric further highlights the design gap. The NVIDIA chip achieves 118.9 million transistors per square millimeter, while the AMD part's transistor count and die size are not recorded in the database. This means the NVIDIA GPU packs significantly more hardware into its silicon.

The shading unit counts are the most dramatic divergence. The AMD Radeon 820M has 128 shading units, 8 texture mapping units, and 4 render output units. The NVIDIA RTX 2000 Max-Q Ada Generation has 3072 shading units, 96 TMUs, and 48 ROPs. The NVIDIA GPU also features 24 ray tracing cores and 96 tensor cores, whereas the AMD part has only 2 ray tracing cores and no tensor cores at all.

Clock behavior differs substantially as well. The AMD Radeon 820M runs at a 400 MHz base clock with a 2800 MHz boost clock. The NVIDIA RTX 2000 Max-Q Ada Generation operates at a 930 MHz base clock and a 1455 MHz boost clock. Despite its lower boost frequency, the NVIDIA GPU compensates through its massive parallel hardware.

Memory architecture is another major divider. The AMD Radeon 820M relies entirely on system-shared memory, with its bandwidth listed as system dependent. The NVIDIA RTX 2000 Max-Q Ada Generation has 8 GB of dedicated GDDR6 memory on a 128-bit bus, delivering 256.0 GB/s of bandwidth. The memory clock on the NVIDIA part runs at 2000 MHz with 16 Gbps effective data rate.

Both GPUs support PCIe 4.0, but with different lane widths. The AMD part uses an x8 interface, while the NVIDIA part uses an x16 interface. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level compatibility is identical.

Where Each One Wins

The AMD Radeon 820M wins in power efficiency and integration simplicity. Its 15 W TDP is less than half of the NVIDIA GPU's 35 W TDP. For thin-and-light portable devices where thermal budgets are tight, the AMD part offers a lower-power integrated solution that requires no dedicated memory allocation beyond system RAM.

The NVIDIA RTX 2000 Max-Q Ada Generation wins in every compute-heavy category. Its 3072 shading units versus 128 gives it overwhelming parallel processing capability. The 96 tensor cores enable AI-accelerated workloads that the AMD part cannot handle at all. The 24 ray tracing cores versus 2 means the NVIDIA GPU can handle real-time ray tracing far more effectively.

The dedicated 8 GB GDDR6 memory with 256.0 GB/s bandwidth gives the NVIDIA GPU a decisive advantage in memory-intensive applications. The AMD part's system-shared memory performance is entirely dependent on the host system's RAM speed and configuration, which introduces variability that the NVIDIA GPU avoids.

The NVIDIA GPU also has a higher pixel rate of 69.84 GPixel/s versus 11.20 GPixel/s on the AMD part, and a texture rate of 139.7 GTexel/s versus 22.40 GTexel/s. These fill rates translate directly to higher resolution rendering capability and more detailed texture work.

Specification Differences

The two GPUs differ across nearly every recorded specification. The process nodes are 4 nm for AMD versus 5 nm for NVIDIA, both fabricated by TSMC. The AMD chip uses the RDNA 3.5 architecture, while NVIDIA uses Ada Lovelace. The AMD part is from the Navi III IGP generation for Strix Point Mobile, while the NVIDIA part is from the Ada-MW generation.

Transistor count is recorded at 18,900 million for NVIDIA, with a die size of 159 mm² and a transistor density of 118.9M per mm². The AMD part's transistor count and die size are unknown. Clock speeds show AMD at 400 MHz base and 2800 MHz boost, while NVIDIA runs at 930 MHz base and 1455 MHz boost.

Memory configuration is entirely different. AMD uses system-shared memory with system-dependent bandwidth. NVIDIA uses 8 GB of GDDR6 on a 128-bit bus with 256.0 GB/s bandwidth and a 2000 MHz memory clock running at 16 Gbps effective.

The compute resources are starkly different: AMD has 128 shading units, 8 TMUs, 4 ROPs, and 2 ray tracing cores. NVIDIA has 3072 shading units, 96 TMUs, 48 ROPs, 24 ray tracing cores, and 96 tensor cores. The FP32 performance is 716.8 GFLOPS for AMD versus 8.940 TFLOPS for NVIDIA, and both have 1:1 FP16 ratios.

Pixel rate is 11.20 GPixel/s for AMD versus 69.84 GPixel/s for NVIDIA. Texture rate is 22.40 GTexel/s for AMD versus 139.7 GTexel/s for NVIDIA. TDP is 15 W for AMD versus 35 W for NVIDIA. The bus interface is PCIe 4.0 x8 for AMD versus PCIe 4.0 x16 for NVIDIA.

Both are IGP slot width with no power connectors and portable-device-dependent display outputs. The release dates are February 28, 2025 for AMD and March 20, 2023 for NVIDIA. AMD's predecessor is Navi II IGP, while NVIDIA's predecessor is Ampere-MW. NVIDIA's successor is Blackwell-MW, while AMD has no recorded successor.

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark scores in the database. However, the specification differences provide clear quantitative comparisons that predict relative performance.

The FP32 compute performance is the most informative metric. The NVIDIA RTX 2000 Max-Q Ada Generation delivers 8.940 TFLOPS, which is 12.5 times the 716.8 GFLOPS of the AMD Radeon 820M. This ratio applies directly to general-purpose compute workloads and shader-heavy rendering tasks.

The texture rate comparison shows NVIDIA at 139.7 GTexel/s versus AMD at 22.40 GTexel/s, a 6.2-fold advantage. The pixel rate comparison shows NVIDIA at 69.84 GPixel/s versus AMD at 11.20 GPixel/s, a 6.2-fold advantage as well. These fill rate differences indicate that the NVIDIA GPU can sustain much higher resolution and anti-aliasing workloads.

Memory bandwidth is another decisive gap. The NVIDIA GPU's 256.0 GB/s of dedicated bandwidth stands in contrast to the AMD part's system-dependent shared memory. In scenarios where memory bandwidth is the limiting factor, the NVIDIA GPU has a fixed, guaranteed bandwidth figure, while the AMD part's performance varies with the host system.

The ray tracing core count of 24 versus 2 indicates a 12-fold advantage for NVIDIA in ray-traced scenes. The tensor core presence, 96 versus zero, means the NVIDIA GPU can accelerate AI-based features like DLSS, while the AMD part has no such hardware.

Both GPUs share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This means software compatibility is equal, but the underlying hardware capabilities differ enormously.

The TDP difference of 15 W versus 35 W means the NVIDIA GPU consumes 20 W more power. This is a trade-off for its substantially higher performance. The AMD part's lower power draw makes it suitable for passively cooled or very low-power designs.

The Verdict

The data indicates a clear performance hierarchy between these two GPUs. The NVIDIA RTX 2000 Max-Q Ada Generation outperforms the AMD Radeon 820M across every compute metric recorded in the database. The FP32 throughput difference of 8.940 TFLOPS versus 716.8 GFLOPS, the texture rate difference of 139.7 GTexel/s versus 22.40 GTexel/s, and the pixel rate difference of 69.84 GPixel/s versus 11.20 GPixel/s all point to a dominant NVIDIA position.

The NVIDIA GPU is the choice for workloads that demand raw graphics performance. Its 3072 shading units, 96 texture mapping units, and 48 render output units provide the parallel hardware needed for modern games and GPU-accelerated applications. The 24 ray tracing cores and 96 tensor cores extend its capability into ray-traced rendering and AI-enhanced features. The 8 GB of dedicated GDDR6 memory with 256.0 GB/s bandwidth ensures consistent performance without dependence on system memory configuration.

The AMD Radeon 820M serves a different purpose. Its 15 W TDP makes it suitable for ultra-portable devices where power consumption is the primary constraint. The system-shared memory design simplifies the device architecture by removing the need for dedicated VRAM. For basic graphics output, video playback, and light productivity tasks, the AMD part provides adequate performance with minimal power draw.

The release timeline also matters. The AMD Radeon 820M launched on February 28, 2025, while the NVIDIA RTX 2000 Max-Q Ada Generation launched on March 20, 2023. The NVIDIA GPU is nearly two years older in release date but still holds a commanding lead in every measured specification.

Both GPUs are currently active in production. The NVIDIA part has a recorded successor in Blackwell-MW, while the AMD part does not. This suggests the NVIDIA GPU is nearing the end of its product cycle, while the AMD part may be earlier in its lifespan.

The percentile ranking for both GPUs is 50 out of all GPUs in the database, indicating they sit at the median of the overall distribution. This is a broad categorization, but the specification gap between them is anything but median. The NVIDIA RTX 2000 Max-Q Ada Generation is positioned as a high-performance mobile solution, while the AMD Radeon 820M is positioned as an entry-level integrated option. Users requiring serious graphics capability should select the NVIDIA GPU based on the recorded data. Users prioritizing minimal power consumption and system simplicity will find the AMD part adequate for basic needs.
