AMD Radeon 820M vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

Where Each One Wins

The data splits this comparison into two entirely separate performance classes. The AMD Radeon 820M is an integrated graphics processor with no recorded benchmark scores in the database, while the NVIDIA GeForce RTX 5070 Ti Mobile has a full set of nine recorded tests. The RTX 5070 Ti Mobile therefore wins every measurable category by default, but the more useful analysis lies in what each device is designed to do.

The RTX 5070 Ti Mobile delivers its strongest results in compute-oriented workloads. Its Geekbench OpenCL score of 143870 and Vulkan score of 139213 show high throughput in general-purpose GPU compute. The PassMark G3D score of 24004 indicates substantial rasterization performance, while the PassMark GPU Compute score of 10101 confirms strong non-graphics processing capability. The AMD Radeon 820M, by contrast, has no benchmark entries, meaning the database contains no direct performance measurements for it.

The AMD side occupies the low-power integrated segment. Its 15 W TDP, system-shared memory, and IGP slot width define a part meant for basic display output and light graphics work inside a portable device. The RTX 5070 Ti Mobile, with its 60 W TDP and dedicated 12 GB GDDR7 memory, targets demanding 3D applications. The 820M wins on power efficiency and system simplicity, though the database records no numbers to quantify that advantage. The RTX 5070 Ti Mobile wins on every recorded performance metric.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The AMD Radeon 820M uses RDNA 3.5 architecture, built on a 4 nm process at TSMC. Its chip is designated Krackan Point 2, and it belongs to the Navi III IGP generation for Strix Point Mobile. The NVIDIA GeForce RTX 5070 Ti Mobile uses Blackwell 2.0 architecture, built on a 5 nm process at TSMC, with the GB205 chip in the GeForce 50 Mobile generation.

Transistor counts reveal the scale difference. The RTX 5070 Ti Mobile contains 31,100 million transistors on a 263 mm² die, giving a transistor density of 118.3M per mm². The 820M's transistor count and die size are recorded as unknown. The RTX 5070 Ti Mobile is a large discrete processor; the 820M is an integrated design sharing a package with other system components.

Ray tracing hardware is present on both, but in very different quantities. The 820M has 2 ray tracing cores, while the RTX 5070 Ti Mobile has 46. Tensor cores exist only on the NVIDIA side, with 184 tensor cores recorded. The AMD part lists no tensor core count, indicating no equivalent AI acceleration hardware in its specification set. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so their API feature levels match at the software interface.

Memory architecture differs fundamentally. The 820M uses system-shared memory of system-dependent bandwidth; the RTX 5070 Ti Mobile has 12 GB of GDDR7 on a 192 bit bus with 672.0 GB/s bandwidth. The AMD part's memory clock is listed as system shared, while the NVIDIA part runs at 1750 MHz with 28 Gbps effective data rate. The bus interface also differs: PCIe 4.0 x8 for the AMD IGP versus PCIe 5.0 x16 for the NVIDIA mobile part.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries comparing these two directly. The RTX 5070 Ti Mobile's individual benchmark results stand as the only recorded performance numbers. Its PassMark G3D score of 24004 places it in the 80th percentile among all GPUs in the database. Its average benchmark score is 35435.

The RTX 5070 Ti Mobile's nearest rivals in the database provide context for its performance tier. The NVIDIA Quadro GV100 scores 35520, which is 0.2% higher than the RTX 5070 Ti Mobile's average. The AMD Radeon Pro Duo scores 35860, 1.2% higher. The NVIDIA A2 scores 34690, which is 2.1% lower. The NVIDIA T1000 scores 36289, 2.4% higher. These deltas show the RTX 5070 Ti Mobile sitting in a tight cluster of professional and workstation GPUs, all within roughly 2.4% of each other.

Individual test scores reinforce this positioning. The Geekbench OpenCL result of 143870 and Vulkan result of 139213 are the highest recorded numbers for this GPU. PassMark scores across different DirectX versions show a spread: DirectX 9 at 259, DirectX 10 at 151, DirectX 11 at 237, and DirectX 12 at 102. The G2D score of 981 covers 2D graphics operations, while the G3D score of 24004 covers 3D rendering. The GPU Compute score of 10101 measures non-graphics parallel processing.

The AMD Radeon 820M has no recorded scores, no average benchmark score, and no nearest rivals in the database. Its percentile versus all GPUs is listed at 50, but with a zero average benchmark score, this figure does not reflect measured performance. The RTX 5070 Ti Mobile's 80th percentile ranking is backed by actual test data across nine separate workloads.

Specification Differences

The core execution resources differ by an order of magnitude. The 820M has 128 shading units, 8 texture mapping units, and 4 render output units. The RTX 5070 Ti Mobile has 5888 shading units, 184 TMUs, and 80 ROPs. These numbers translate directly into pixel and texture throughput: 11.20 GPixel/s and 22.40 GTexel/s for the AMD part, versus 115.8 GPixel/s and 266.2 GTexel/s for the NVIDIA part.

Compute throughput shows the same pattern. The 820M delivers 716.8 GFLOPS FP32 and the same 716.8 GFLOPS FP16 with a 1:1 ratio. The RTX 5070 Ti Mobile delivers 17.04 TFLOPS FP32 and 17.04 TFLOPS FP16, also at a 1:1 ratio. The NVIDIA part offers roughly 24 times the FP32 throughput, though the AMD part's lower clock speed contributes to this gap. The 820M boosts to 2800 MHz from a 400 MHz base; the RTX 5070 Ti Mobile boosts to 1447 MHz from an 847 MHz base.

Power and physical configuration differ substantially. The 820M has a 15 W TDP; the RTX 5070 Ti Mobile has a 60 W TDP. Both use the IGP slot width and have no power connectors, with display outputs dependent on the portable device. The NVIDIA part uses PCIe 5.0 x16, while the AMD part uses PCIe 4.0 x8.

Release timing is identical. Both parts have a release date of 2025-02-28. The 820M's predecessor is listed as Navi II IGP, while the RTX 5070 Ti Mobile's predecessor is GeForce 40 Mobile. Neither has a successor recorded. Both are marked as Active in production status. Neither has a launch MSRP in the database. The 820M's series is null, while the RTX 5070 Ti Mobile belongs to the GeForce 50-series.

The Verdict

The recorded data separates these two GPUs into different application spaces. The RTX 5070 Ti Mobile is a high-performance discrete mobile GPU with substantial compute resources, dedicated GDDR7 memory, and a full set of benchmark results. Its 80th percentile ranking and average score of 35435 place it alongside professional workstation parts like the Quadro GV100 and Radeon Pro Duo, all within a few percentage points of each other. Its 5888 shading units, 184 tensor cores, and 672.0 GB/s memory bandwidth make it suitable for compute-heavy and graphics-intensive workloads in a portable device.

The AMD Radeon 820M is an integrated processor with no recorded performance data. Its 15 W TDP, system-shared memory, and 128 shading units define a low-power part for basic graphics duties. The 2 ray tracing cores provide hardware ray tracing support, but the overall resource count is minimal. Its 50th percentile listing carries no benchmark backing, so no performance claims can be made from the database.

Users requiring measured 3D rendering, GPU compute, or AI acceleration have one clear option in the RTX 5070 Ti Mobile. Users prioritizing minimal power draw and system integration would choose the 820M, which consumes 15 W versus 60 W and requires no dedicated memory. The RTX 5070 Ti Mobile's 31,100 million transistors on a 263 mm² die represent a high-end design, while the 820M's unknown transistor count reflects its integrated nature. The RTX 5070 Ti Mobile is the only one of the two with benchmark evidence, and that evidence shows a part performing at a professional GPU level.
