AMD Radeon 820M vs NVIDIA GeForce RTX 4060 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a stark performance disparity between the AMD Radeon 820M and the NVIDIA GeForce RTX 4060 Mobile. The database contains a full benchmark suite for the RTX 4060 Mobile, while the Radeon 820M has no recorded benchmark scores. This absence is itself informative: the RTX 4060 Mobile holds a 67th percentile ranking among all GPUs in the database, while the Radeon 820M sits at the 50th percentile.

Looking at the NVIDIA part's results, the strongest showing comes from the Geekbench Vulkan test, where it scores 89,569. The Geekbench OpenCL result is nearly identical at 89,420. These two numbers confirm that the RTX 4060 Mobile delivers consistent compute performance across different API workloads. The Passmark G3D score of 17,469 further supports this, as it represents a full 3D graphics workload rather than a synthetic compute test.

The RTX 4060 Mobile's Passmark GPU Compute score of 6,816 demonstrates that general-purpose compute tasks run at a substantially lower level than graphics workloads. The DirectX 11 Passmark score of 157 and DirectX 9 score of 216 both outpace the DirectX 12 score of 73, which suggests the architecture handles older API paths with relatively higher throughput. The DirectX 10 score of 107 sits between these values.

The Passmark G2D score of 730 shows 2D desktop and GUI acceleration performance. This is a separate metric from the 3D and compute numbers, and it indicates that the card handles basic display tasks without issue.

The Verdict

The data indicates two GPUs with fundamentally different performance envelopes. The RTX 4060 Mobile delivers 11.61 TFLOPS of FP32 throughput, while the Radeon 820M delivers 716.8 GFLOPS. That is a 16.2 times difference in raw floating-point compute. The texture rate tells the same story: 181.4 GTexel/s versus 22.40 GTexel/s, an 8.1 times gap. Pixel rate shows 90.72 GPixel/s versus 11.20 GPixel/s, a difference of 8.1 times.

The RTX 4060 Mobile compares closely with several desktop and mobile parts in the database. Its average benchmark score of 22,729 sits within 1.3% of the NVIDIA GeForce RTX 5060 Mobile, 0.8% above the AMD Radeon RX 7700 XT, 0.7% below the NVIDIA GeForce RTX 2080, and 1.3% above the Intel Arc B580. This places the RTX 4060 Mobile in a well-populated performance tier.

The Radeon 820M is an integrated graphics processor with 128 shading units, 8 TMUs, and 4 ROPs. The RTX 4060 Mobile, by contrast, has 3,072 shading units, 96 TMUs, and 48 ROPs. The NVIDIA part has 24 RT cores and 96 tensor cores, while the AMD part has 2 RT cores and no tensor cores. These are different classes of hardware.

Architecture Differences

The AMD Radeon 820M uses the RDNA 3.5 architecture, built on a 4 nm process at TSMC. It is part of the Navi III IGP generation for Strix Point Mobile, with a chip designated Krackan Point 2. The NVIDIA GeForce RTX 4060 Mobile uses Ada Lovelace, built on a 5 nm process at TSMC, with the AD107 chip and a transistor count of 18,900 million on a 159 mm² die. The transistor density works out to 118.9M per mm².

The AMD part has no dedicated memory. It uses system shared memory, with system-dependent bandwidth. The NVIDIA part has 8 GB of GDDR6 on a 128-bit bus, delivering 256.0 GB/s of bandwidth. The RTX 4060 Mobile's memory clock is listed at 2000 MHz with 16 Gbps effective data rate.

Clock behavior differs sharply. The AMD part runs at a 400 MHz base and 2800 MHz boost. The NVIDIA part runs at 1545 MHz base and 1890 MHz boost. The RTX 4060 Mobile's lower boost clock is offset by its much larger execution resource pool. Power draw reflects this: the Radeon 820M has a 15 W TDP, while the RTX 4060 Mobile has a 115 W TDP. Neither requires external power connectors, and both are classified as IGP slot width, meaning they are not discrete expansion cards.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both use a PCIe 4.0 x8 bus interface. Display outputs are portable device dependent for both. The Radeon 820M supports FP16 at 716.8 GFLOPS with a 1:1 ratio, and the RTX 4060 Mobile supports FP16 at 11.61 TFLOPS, also 1:1.

The Radeon 820M's predecessor is listed as Navi II IGP, and its release date is February 28, 2025. The RTX 4060 Mobile's predecessor is GeForce 30 Mobile, its successor is GeForce 50 Mobile, and its release date is January 2, 2023. Both parts are currently listed as Active in production status.

Where Each One Wins

The RTX 4060 Mobile wins in every measurable performance category where a direct comparison is possible. Its 3,072 shading units, 96 TMUs, and 48 ROPs give it overwhelming advantages in pixel rate, texture rate, and FP32 compute. The 8 GB GDDR6 memory with 256.0 GB/s bandwidth provides dedicated high-speed storage for frame buffers and textures, which is critical for modern game rendering.

The Radeon 820M's advantages are of a different nature. Its 15 W TDP means it draws 100 W less than the RTX 4060 Mobile. It is an integrated processor with no power connectors, designed for portable devices where battery life and thermal limits take priority. Its 4 nm process node is smaller than the RTX 4060 Mobile's 5 nm node, which contributes to its efficiency profile.

In terms of release timing, the Radeon 820M is the newer part, released in February 2025 versus January 2023 for the RTX 4060 Mobile. The Radeon 820M's generation is listed as Navi III IGP for Strix Point Mobile, while the RTX 4060 Mobile belongs to the GeForce 40 Mobile generation.

For users who need maximum graphics throughput, the RTX 4060 Mobile is the only viable option based on the data. Its average benchmark score of 22,729 places it in the 67th percentile of all GPUs, and its nearest rivals are all within a narrow 1.3% band. The Radeon 820M has no recorded benchmarks and no nearest rivals in the database, which means its real-world performance cannot be quantified with the available data.

For users who prioritize low power consumption in a portable device, the Radeon 820M's 15 W TDP and integrated design present a clear efficiency advantage. The RTX 4060 Mobile's 115 W TDP requires substantially more thermal headroom and battery capacity.
