AMD Radeon 820M vs NVIDIA GeForce RTX 4050 Max-Q Comparison

The Verdict

The recorded data shows a decisive performance hierarchy between these two mobile graphics solutions. The NVIDIA GeForce RTX 4050 Max-Q is in a completely different performance class, with its specifications indicating roughly 11.5 times the FP32 compute throughput of the AMD Radeon 820M. The RTX 4050 Max-Q should be selected for any workload involving 3D rendering, modern game titles, ray tracing, or AI-accelerated features. The AMD Radeon 820M, as an integrated graphics processor with 128 shading units and a 15 W TDP, is suited exclusively for basic desktop compositing, light 2D workloads, and legacy or esports-level 3D applications where its modest 716.8 GFLOPS of FP32 performance can suffice. The data indicates the RTX 4050 Max-Q delivers 8.218 TFLOPS FP32, 20 ray tracing cores, 80 tensor cores, and 6 GB of dedicated GDDR6 memory, making it the only viable option for compute-intensive tasks. The Radeon 820M holds no benchmark wins in the database, and its specifications place it below the RTX 4050 Max-Q in every measurable compute category.

Architecture Differences

The AMD Radeon 820M uses the RDNA 3.5 architecture on TSMC's 4 nm process node, fabricated as part of the Navi III IGP generation for Strix Point Mobile. Its chip is designated Krackan Point 2, and it operates with a base clock of 400 MHz and a boost clock of 2800 MHz. The GPU contains 128 shading units, 8 texture mapping units, 4 raster output pipelines, and 2 ray tracing cores. Its memory subsystem is entirely system-shared, with no dedicated VRAM, and memory bandwidth is listed as system dependent. The Radeon 820M draws a 15 W TDP and connects via PCIe 4.0 x8.

The NVIDIA GeForce RTX 4050 Max-Q uses the Ada Lovelace architecture on TSMC's 5 nm process node, built around the AD107 chip with 18,900 million transistors on a 159 mm² die, yielding a transistor density of 118.9 million per square millimeter. Its base clock is 1140 MHz with a boost clock of 1605 MHz, significantly lower clock speeds than the AMD part, but this is offset by a far larger compute configuration. The RTX 4050 Max-Q contains 2560 shading units, 80 texture mapping units, 48 raster output pipelines, 20 ray tracing cores, and 80 tensor cores. It has 6 GB of GDDR6 memory on a 96-bit bus with 192.0 GB/s bandwidth, and memory runs at 2000 MHz with 16 Gbps effective speed. The NVIDIA part has a 35 W TDP and also uses PCIe 4.0 x8.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and both are classified as IGP slot width with no power connectors and portable-device-dependent display outputs. The architectural gulf is defined by the NVIDIA part's dedicated memory and substantially larger execution resources, while the AMD part relies on shared system memory and a much smaller silicon footprint.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark scores for these two parts, but the specification comparison provides clear performance deltas. The RTX 4050 Max-Q delivers 8.218 TFLOPS of FP32 compute, which is exactly 11.47 times the 716.8 GFLOPS of the Radeon 820M. This ratio also applies to FP16 performance, as both parts operate at 1:1 FP16 to FP32 rates, with the NVIDIA part again at 8.218 TFLOPS versus 716.8 GFLOPS.

Pixel throughput shows a 6.88 times advantage for the RTX 4050 Max-Q at 77.04 GPixel/s versus 11.20 GPixel/s for the AMD part. Texture fill rate favors NVIDIA by 5.73 times, with 128.4 GTexel/s versus 22.40 GTexel/s. The RTX 4050 Max-Q has 20 ray tracing cores and 80 tensor cores, while the Radeon 820M has only 2 ray tracing cores and no tensor cores at all. Memory bandwidth is a separate category: the NVIDIA part has 192.0 GB/s on dedicated GDDR6, while the AMD part has system-dependent bandwidth with no dedicated memory. The RTX 4050 Max-Q also offers 6 GB of VRAM, whereas the Radeon 820M has none.

Clock speeds do not favor either part uniformly. The AMD Radeon 820M has a 2800 MHz boost clock versus 1605 MHz on the RTX 4050 Max-Q, a 74.5 percent higher boost frequency. However, the NVIDIA part compensates with 20 times the shading units, 10 times the texture mapping units, and 12 times the raster output pipelines. The TDP difference is also notable: 15 W for AMD versus 35 W for NVIDIA, but the performance per watt in raw throughput strongly favors the NVIDIA part given the compute ratio.

Specification Differences

The two GPUs differ in nearly every specification field. The AMD Radeon 820M uses the RDNA 3.5 architecture on a 4 nm process, while the NVIDIA RTX 4050 Max-Q uses Ada Lovelace on a 5 nm process. The AMD chip is Krackan Point 2 with unknown transistor count and die size, while the NVIDIA AD107 chip has 18,900 million transistors on a 159 mm² die. The AMD part has base and boost clocks of 400 MHz and 2800 MHz respectively, versus 1140 MHz and 1605 MHz on the NVIDIA part. The Radeon 820M uses system-shared memory with system-dependent bandwidth, while the RTX 4050 Max-Q has 6 GB GDDR6, a 96-bit bus, and 192.0 GB/s bandwidth. Shading units number 128 versus 2560, TMUs number 8 versus 80, ROPs number 4 versus 48, and ray tracing cores number 2 versus 20. The NVIDIA part additionally has 80 tensor cores, which the AMD part lacks entirely. Pixel rate is 11.20 GPixel/s versus 77.04 GPixel/s, texture rate is 22.40 GTexel/s versus 128.4 GTexel/s, and FP32 compute is 716.8 GFLOPS versus 8.218 TFLOPS. TDP is 15 W versus 35 W. Both parts share PCIe 4.0 x8, no power connectors, IGP slot width, and identical API support. Release dates differ, with the Radeon 820M released on 2025-02-28 and the RTX 4050 Max-Q on 2023-01-02. The AMD predecessor is Navi II IGP, while the NVIDIA predecessor is GeForce 30 Mobile and successor is GeForce 50 Mobile.

Where Each One Wins

The AMD Radeon 820M wins in power efficiency and clock frequency. Its 15 W TDP is 20 W lower than the RTX 4050 Max-Q's 35 W TDP, making it suitable for ultra-low-power portable devices where thermal and battery constraints are paramount. Its 2800 MHz boost clock exceeds the NVIDIA part's 1605 MHz boost by 74.5 percent, and its 4 nm process node is smaller than the 5 nm node used by NVIDIA. These advantages matter for basic integrated graphics duties: desktop rendering, video playback, and lightweight productivity applications where the system-shared memory and 716.8 GFLOPS of compute are sufficient. The Radeon 820M also has a newer release date of 2025-02-28 versus 2023-01-02 for the NVIDIA part.

The NVIDIA GeForce RTX 4050 Max-Q wins in every raw performance category. It has 20 times the shading units, 10 times the texture mapping units, 12 times the raster output pipelines, and 10 times the ray tracing cores. Its FP32 compute is 8.218 TFLOPS versus 716.8 GFLOPS, a 11.47 times advantage. Pixel rate is 77.04 GPixel/s versus 11.20 GPixel/s, and texture rate is 128.4 GTexel/s versus 22.40 GTexel/s. The dedicated 6 GB GDDR6 memory with 192.0 GB/s bandwidth eliminates reliance on system memory, and the 80 tensor cores enable AI-accelerated features that the AMD part cannot execute. The RTX 4050 Max-Q is the appropriate choice for 3D rendering, modern game titles, ray-traced effects, and any workload that benefits from tensor core acceleration. The Radeon 820M has no recorded benchmark wins, and its 50th percentile ranking across all GPUs matches the RTX 4050 Max-Q, but the specification gap indicates this parity reflects the AMD part's position among integrated graphics rather than competition with discrete-class mobile GPUs.
