AMD Radeon 820M vs NVIDIA GeForce RTX 4070 SUPER Comparison

Head-to-Head Benchmarks

The recorded data shows a fundamental performance gap between these two graphics solutions. The AMD Radeon 820M is an integrated graphics processor with 128 shading units, while the NVIDIA GeForce RTX 4070 SUPER is a discrete add-in card with 7,168 shading units. The benchmark database contains no direct head-to-head comparison entries, but the available individual benchmark results and architectural specifications establish a clear hierarchy.

The NVIDIA GeForce RTX 4070 SUPER delivers an average benchmark score of 43,223 across all recorded tests. This places it in the 83rd percentile of all GPUs in the database. Its nearest rivals in the database include the NVIDIA Quadro M6000 24 GB with an average score of 43,262, a delta of -0.1%, and the NVIDIA GeForce RTX 5050 Mobile with an average score of 43,268, also a delta of -0.1%. The NVIDIA Quadro M6000 scores 43,301, a delta of -0.2%, and the NVIDIA GeForce RTX 4090 Mobile scores 43,667, a delta of -1%. The RTX 4070 SUPER sits within 1% of these high-end competitors, confirming its position near the top of the performance distribution.

The AMD Radeon 820M has no recorded benchmark scores in the database. Its average benchmark score is listed as 0, and it holds a 50th percentile position among all GPUs. The absence of measured results means the database cannot provide a direct numerical comparison of application performance. However, the specification differences provide a basis for analysis.

The raw compute figures show the scale of the divide. The RTX 4070 SUPER produces 35.48 TFLOPS of FP32 compute, while the Radeon 820M produces 716.8 GFLOPS. That is a difference of roughly 49.5 times in raw floating-point throughput. The pixel throughput tells a similar story: the RTX 4070 SUPER renders 198.0 GPixel/s versus 11.20 GPixel/s for the 820M, a factor of approximately 17.7. Texture fill rates differ even more sharply, with the RTX 4070 SUPER at 554.4 GTexel/s compared to 22.40 GTexel/s for the 820M, a factor of about 24.8.

The RTX 4070 SUPER also carries dedicated ray tracing hardware in the form of 56 RT cores and 224 tensor cores. The Radeon 820M includes 2 RT cores but no tensor cores. The RTX 4070 SUPER supports 12 GB of GDDR6X memory across a 192-bit bus with 504.2 GB/s of bandwidth. The Radeon 820M uses system-shared memory, with bandwidth dependent on the host system, a figure the database cannot quantify.

Memory performance is one of the largest practical separators. The RTX 4070 SUPER's 504.2 GB/s dedicated bandwidth is a discrete design advantage. The 820M's memory bandwidth is labeled "System Dependent" in the database, meaning it shares the host's memory subsystem and is subject to the platform's capabilities. This affects texture streaming, frame buffer access, and overall responsiveness in memory-intensive workloads.

The Verdict

The data indicates two products aimed at entirely different segments. The NVIDIA GeForce RTX 4070 SUPER is a dual-slot, 220 W discrete graphics card with a 1x 16-pin power connector and a suggested PSU of 550 W. It measures 267 mm in length, 112 mm in height, and 42 mm in width. Its launch MSRP was 599 USD. The AMD Radeon 820M is an integrated graphics processor with a 15 W TDP, no power connectors, and no physical dimensions listed, as it is built into the host processor.

The RTX 4070 SUPER produces more than 49 times the FP32 compute of the 820M, 17.7 times the pixel rate, and 24.8 times the texture rate. It has 56 times the shading units, 28 times the texture mapping units, and 20 times the raster operation units. These ratios, drawn directly from the database, describe a product class difference rather than a generational difference.

The RTX 4070 SUPER was released on 2024-01-16 and is marked as End-of-life in production status, with the GeForce 50 as its successor. The Radeon 820M was released on 2025-02-28, is marked as Active, and belongs to the Krackan Point 2 chip family with RDNA 3.5 architecture. The RTX 4070 SUPER is based on the AD104 chip with Ada Lovelace architecture on a 5 nm process from TSMC. The Radeon 820M uses a 4 nm process from TSMC.

For users selecting between these two parts, the database shows that the Radeon 820M is a low-power integrated solution with no recorded performance benchmarks and a 50th percentile standing. The RTX 4070 SUPER is a high-performance discrete card with recorded scores in ten separate benchmarks and an 83rd percentile standing. No benchmark data exists to suggest the 820M can approach the RTX 4070 SUPER in any measured workload.

Where Each One Wins

The NVIDIA GeForce RTX 4070 SUPER wins every category where the database contains measurable data. Its recorded benchmarks include 3DMark Steel Nomad DX12 with a score of 4,627, Geekbench OpenCL with 172,795, Geekbench Vulkan with 205,624, Passmark DirectX 10 with 167, Passmark DirectX 11 with 273, Passmark DirectX 12 with 110, Passmark DirectX 9 with 344, Passmark G2D with 1,184, Passmark G3D with 29,995, and Passmark GPU Compute with 17,108. Its average benchmark score of 43,223 reflects consistent high-end performance across these synthetic tests.

The AMD Radeon 820M has no recorded benchmarks. Its advantage lies in power consumption and physical integration. The database lists its TDP at 15 W, compared to 220 W for the RTX 4070 SUPER. It requires no power connectors, no expansion slot beyond the integrated processor socket, and no dedicated cooling solution beyond what the host system provides. Its bus interface is PCIe 4.0 x8, while the RTX 4070 SUPER uses PCIe 4.0 x16. The 820M's display outputs are listed as "Portable Device Dependent," indicating it is designed for mobile and compact systems where the RTX 4070 SUPER's 267 mm length and dual-slot footprint would not fit.

The RTX 4070 SUPER supports 12 GB of dedicated GDDR6X memory. The 820M shares system memory, with size, type, and bus width all listed as "System Shared." For workloads that depend on dedicated frame buffer capacity, such as high-resolution rendering or large texture sets, the RTX 4070 SUPER has a structural advantage that the database quantifies through its 504.2 GB/s bandwidth figure.
