AMD Radeon 820M vs NVIDIA GeForce RTX 4050 Mobile Comparison

Head-to-Head Benchmarks

The data shows a decisive performance gap between these two mobile graphics solutions. The NVIDIA GeForce RTX 4050 Mobile holds a commanding lead across every recorded benchmark, with the AMD Radeon 820M having no benchmark scores registered in the database. This absence of measurable results for the AMD part means the head-to-head comparison is one-sided by default.

The RTX 4050 Mobile posts an average benchmark score of 19049 across its recorded tests. Its nearest rivals include the AMD Radeon RX 6600 at 19036 (0.1% slower), the NVIDIA Quadro K6000 at 19030 (0.1% slower), and the NVIDIA RTX 2000 Ada Generation at 18954 (0.5% slower). The only listed competitor that edges it out is the NVIDIA Tesla K20m at 19089, which is 0.2% faster. These margins are extremely tight, indicating the RTX 4050 Mobile sits in a well-populated performance tier where even small percentage differences matter.

In raw compute tests, the RTX 4050 Mobile delivers an OpenCL score of 74748 and a Vulkan score of 75235 on Geekbench. These figures place it well above the median GPU percentile of 63, meaning it outperforms roughly three out of five GPUs in the database. The PassMark suite shows a G3D score of 14423 and a GPU compute score of 5947, alongside DirectX 9, 10, 11, and 12 scores of 184, 79, 130, and 61 respectively. The G2D score of 633 reflects 2D graphics acceleration capability.

The AMD Radeon 820M carries a percentile rank of 50, placing it exactly at the median of all GPUs in the database, but with zero benchmark scores recorded. Its average benchmark score is listed as 0, and it has no nearest rivals defined. This makes quantitative comparison impossible beyond the architectural specifications. The recorded data indicates that the RTX 4050 Mobile is the only one of the two with actual performance measurements, and those measurements show a part that is competitive with desktop-class discrete GPUs like the Radeon RX 6600.

Where Each One Wins

Based strictly on recorded data, the NVIDIA GeForce RTX 4050 Mobile wins every measurable category. It has benchmark scores across nine different tests, ranging from legacy DirectX 9 workloads to modern Vulkan and OpenCL compute. Its highest relative strength appears in Geekbench Vulkan (75235) and OpenCL (74748), suggesting strong general-purpose compute and modern API performance. The PassMark DirectX 9 score of 184 is its best legacy API result, while DirectX 12 scores 61, indicating newer API workloads are handled but with lower absolute numbers.

The AMD Radeon 820M has no wins in the database because no benchmarks are recorded for it. However, its architectural characteristics point to specific usage scenarios where it might be competitive. As an integrated graphics processor (IGP) with a 15 W TDP, it is designed for power-constrained portable devices. The RTX 4050 Mobile, despite also being listed with an IGP slot width, carries a 50 W TDP, which is more than three times higher. In fanless or passively cooled thin-and-light laptops, the Radeon 820M's lower power draw could be an advantage, but the database records no performance data to confirm this.

The RTX 4050 Mobile's memory configuration gives it a clear edge in bandwidth-sensitive workloads. It uses 6 GB of GDDR6 on a 96-bit bus with 192.0 GB/s bandwidth. The Radeon 820M relies on system shared memory with system-dependent bandwidth, which is typically slower and subject to contention with the CPU. For texture-heavy or large-dataset workloads, the dedicated memory interface of the NVIDIA part is a structural advantage.

Architecture Differences

The two GPUs come from different manufacturers and use fundamentally different architectures. The AMD Radeon 820M is built on RDNA 3.5, using the Krackan Point 2 chip, and belongs to the Navi III IGP (Strix Point Mobile) generation. It is fabricated on a 4 nm process at TSMC. The NVIDIA GeForce RTX 4050 Mobile uses Ada Lovelace architecture with the AD107 chip, part of the GeForce 40 Mobile generation, on a 5 nm process also from TSMC. The AMD part uses a more advanced process node by one nanometer, which typically allows higher transistor density and lower power per transistor.

The compute resources differ substantially. The Radeon 820M has 128 shading units, 8 texture mapping units (TMUs), and 4 render output units (ROPs). The RTX 4050 Mobile has 2560 shading units, 80 TMUs, and 48 ROPs. That is 20 times more shading units, 10 times more TMUs, and 12 times more ROPs. The NVIDIA part also includes 20 ray tracing cores and 80 tensor cores, while the AMD part has 2 ray tracing cores and no tensor cores listed.

Clock speeds show an interesting contrast. The Radeon 820M has a base clock of 400 MHz and a boost clock of 2800 MHz, a 7x increase from base to boost. The RTX 4050 Mobile runs at a base of 1455 MHz and boosts to 1755 MHz, a more modest 1.2x ratio. The AMD part relies heavily on boost behavior to reach its rated performance, while the NVIDIA part maintains higher sustained clocks.

The memory subsystem is radically different. The Radeon 820M uses system shared memory with system-dependent bandwidth, while the RTX 4050 Mobile has 6 GB of dedicated GDDR6 on a 96-bit bus delivering 192.0 GB/s. The NVIDIA part's memory clock is listed at 2000 MHz with 16 Gbps effective data rate.

Pixel and texture rates reflect the resource disparity. The Radeon 820M produces 11.20 GPixel/s and 22.40 GTexel/s. The RTX 4050 Mobile reaches 84.24 GPixel/s and 140.4 GTexel/s. FP32 compute is 716.8 GFLOPS for the AMD part versus 8.986 TFLOPS for the NVIDIA part, a 12.5x difference. Both support FP16 at 1:1 ratio, meaning the same throughput as FP32.

Transistor counts are only listed for the NVIDIA part: 18,900 million transistors on a 159 mm² die, giving a density of 118.9M per mm². The AMD part's transistor count and die size are unknown. The RTX 4050 Mobile also has a defined transistor density figure, while the Radeon 820M does not.

Both GPUs share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both use PCIe 4.0 x8 interfaces and have no power connectors, with portable device dependent display outputs. The RTX 4050 Mobile was released on 2023-01-02, while the Radeon 820M came later on 2025-02-28.

The Verdict

The recorded data leaves no ambiguity for performance-focused users. The NVIDIA GeForce RTX 4050 Mobile is the only one of the two with any benchmark scores, and those scores place it at the 63rd percentile of all GPUs, competitive with desktop parts like the Radeon RX 6600 and RTX 2000 Ada Generation. Its 8.986 TFLOPS FP32 compute, 192.0 GB/s memory bandwidth, and 20 ray tracing cores make it suitable for demanding gaming and compute workloads.

The AMD Radeon 820M, with zero recorded benchmarks and a 50th percentile rank, cannot be positioned against the RTX 4050 Mobile on measured performance. Its 15 W TDP and integrated design suggest it targets ultraportable systems where power efficiency is prioritized over raw throughput. The 4 nm process node and high boost clock of 2800 MHz indicate architectural efficiency, but without benchmark data, its real-world performance remains unquantified in this database.

Users who need discrete-level graphics performance in a laptop should select the RTX 4050 Mobile. Users who prioritize low power consumption in a thin-and-light chassis and do not require dedicated VRAM might consider the Radeon 820M, but they should be aware that no performance measurements support that choice. The data indicates the NVIDIA part is the only option with verified capability.
