AMD Radeon 820M vs NVIDIA RTX 3500 Embedded Ada Generation Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results for the AMD Radeon 820M and NVIDIA RTX 3500 Embedded Ada Generation. Both entries have zero recorded benchmark scores, zero wins, and no nearest rival comparisons. The measured data sheet shows both GPUs at the 50th percentile of all GPUs, but with zero average benchmark scores, this percentile reflects their placement in the product stack rather than any measured performance.

What the recorded data does provide is a stark contrast in raw specification ceilings. The NVIDIA RTX 3500 Embedded Ada Generation delivers 23.04 TFLOPS FP32 performance, while the AMD Radeon 820M delivers 716.8 GFLOPS FP32. That is a 32.1x difference in theoretical peak compute, a ratio that dominates every other comparison between the two parts. The NVIDIA solution processes 144.0 GPixel/s and 360.0 GTexel/s, while the AMD part processes 11.20 GPixel/s and 22.40 GTexel/s. The pixel throughput gap is 12.9x, the texture throughput gap is 16.1x.

Memory bandwidth shows a similar chasm. The RTX 3500 Embedded Ada Generation uses 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s. The Radeon 820M uses system shared memory with bandwidth listed as system dependent, meaning its effective bandwidth cannot be stated as a fixed figure from the database. The NVIDIA part's fixed 432.0 GB/s is the only concrete bandwidth number recorded.

The Radeon 820M does hold advantages in certain clock metrics. Its boost clock reaches 2800 MHz, compared to 2250 MHz for the RTX 3500 Embedded Ada Generation. The AMD base clock of 400 MHz is far lower than NVIDIA's 1725 MHz base clock, indicating a wider dynamic range for the integrated part. The Radeon 820M also uses a smaller process node at 4 nm versus 5 nm for NVIDIA, though both are fabricated by TSMC.

Architecture Differences

The architectural divide between these two GPUs is absolute. The AMD Radeon 820M is an integrated graphics processor built on RDNA 3.5 architecture, part of the Navi III IGP generation designed for Strix Point Mobile platforms. Its chip is Krackan Point 2, built on a 4 nm TSMC process. The NVIDIA RTX 3500 Embedded Ada Generation is a discrete-class embedded GPU using Ada Lovelace architecture, built on the AD104 chip with a 5 nm TSMC process.

The NVIDIA part carries 35,800 million transistors on a 294 mm² die, with a transistor density of 121.8M per mm².

Both GPUs support DirectX 12 Ultimate (12_2) and OpenGL 4.6, and both support Vulkan 1.4. The memory subsystems diverge completely. The NVIDIA part uses dedicated 12 GB of GDDR6 with a 192-bit bus. The AMD part uses system shared memory with a system shared bus width, making its memory configuration dependent on the host platform. The NVIDIA GPU has a fixed 432.0 GB/s bandwidth; the AMD GPU's bandwidth is listed as system dependent.

The NVIDIA RTX 3500 Embedded Ada Generation has a TDP of 100 W and includes a suggested PSU of 300 W in its specifications. The AMD Radeon 820M has a TDP of 15 W. Both use PCIe 4.0, but the NVIDIA part uses x16 while the AMD part uses x8. The NVIDIA GPU lists no display outputs, while the AMD GPU's display outputs are portable device dependent. Both are listed as IGP slot width, meaning neither occupies a standard expansion slot. The NVIDIA part has no power connectors listed, and the AMD part also has no power connectors listed.

The release dates place the NVIDIA GPU first at March 20, 2023, with the AMD GPU following on February 28, 2025. The NVIDIA part is the successor to the Ampere-MW generation and has a successor listed as Blackwell-MW. The AMD part lists its predecessor as Navi II IGP and has no successor listed.

Where Each One Wins

The NVIDIA RTX 3500 Embedded Ada Generation wins decisively in every fixed performance metric recorded in the database. It delivers 23.04 TFLOPS FP32 versus 716.8 GFLOPS FP32 for the AMD part, a 32.1x advantage. Its 144.0 GPixel/s pixel rate exceeds the AMD part's 11.20 GPixel/s by 12.9x. Its 360.0 GTexel/s texture rate exceeds the AMD part's 22.40 GTexel/s by 16.1x. The NVIDIA GPU provides 12 GB of dedicated GDDR6 memory with a fixed 432.0 GB/s bandwidth, while the AMD GPU relies on system shared memory with system dependent bandwidth.

The NVIDIA part also carries more than 40x the shading units (5120 versus 128), 20x the TMUs (160 versus 8), and 16x the ROPs (64 versus 4). It has 40 ray tracing cores versus 2 for the AMD part, and it has 160 tensor cores while the AMD part has none listed. The NVIDIA GPU's 100 W TDP and 300 W suggested PSU reflect a power envelope appropriate for a discrete-class embedded part.

The AMD Radeon 820M wins in the metrics that matter for integrated graphics deployment. Its 15 W TDP is 6.7x lower than the NVIDIA part's 100 W TDP. Its boost clock of 2800 MHz is 24.4% higher than the NVIDIA part's 2250 MHz boost clock. Its 4 nm process node is one generation ahead of the 5 nm node used by the NVIDIA part. The AMD GPU is also newer, released on February 28, 2025, versus March 20, 2023, for the NVIDIA part.

The AMD Radeon 820M also carries a PCIe 4.0 x8 interface, which may be sufficient for an integrated part, while the NVIDIA GPU uses PCIe 4.0 x16. The AMD part lists portable device dependent display outputs, meaning it can drive displays in mobile form factors, while the NVIDIA part lists no outputs, indicating it is designed for compute or rendering workloads without direct display attachment.

The Verdict

The recorded data draws a clear line between these two products. The NVIDIA RTX 3500 Embedded Ada Generation is a high-throughput embedded GPU designed for workloads that demand maximum compute, memory bandwidth, and rendering capability. Its 23.04 TFLOPS FP32, 432.0 GB/s fixed bandwidth, 12 GB of dedicated GDDR6, and 160 tensor cores position it for compute-heavy tasks such as AI inference, professional rendering, and high-resolution graphics processing. Its 100 W TDP and 300 W suggested PSU indicate a system builder must plan for substantial power delivery.

The AMD Radeon 820M serves a different purpose entirely. Its 15 W TDP, system shared memory, and integrated design place it in low-power mobile platforms where efficiency and portability take priority over raw throughput. Its higher boost clock of 2800 MHz and newer 4 nm process node suggest it can operate efficiently within tight thermal envelopes. Its 128 shading units and 2 ray tracing cores are modest by comparison but appropriate for an integrated part that shares system resources.

The database shows no measured benchmark results for either GPU, so conclusions rest entirely on specification sheets. The NVIDIA part dominates every fixed performance metric by margins ranging from 12.9x in pixel rate to 32.1x in FP32 compute. The AMD part dominates in power efficiency and integration flexibility, with a 6.7x lower TDP and system shared memory that eliminates the need for dedicated VRAM allocation.

For users selecting a GPU for maximum compute throughput, dedicated memory bandwidth, or tensor core acceleration, the NVIDIA RTX 3500 Embedded Ada Generation is the only choice supported by the recorded data. For users selecting a GPU for low-power integrated graphics in a portable device, the AMD Radeon 820M offers the only viable power envelope. The two parts do not compete in the same segment; the data indicates they serve disjoint use cases.
