AMD Radeon 820M vs NVIDIA RTX 5880 Ada Generation Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for the AMD Radeon 820M versus the NVIDIA RTX 5880 Ada Generation. The Radeon 820M has no recorded benchmark scores, average score, or nearest rivals in the dataset. The RTX 5880 Ada Generation, by contrast, has a full set of recorded measurements across eight tests.

The RTX 5880 Ada Generation delivers a Geekbench OpenCL score of 326,898. Its PassMark G3D score is 25,096, which places it in the 85th percentile among all GPUs in the database. The average benchmark score across all recorded tests for this card is 45,972. In PassMark GPU compute, it records 14,208 points. Additional PassMark results include 777 for G2D, 335 for DirectX 9, 228 for DirectX 11, 167 for DirectX 10, and 70 for DirectX 12.

Because the Radeon 820M has no benchmark entries, there are no exact numeric deltas to calculate between the two parts. The absence of data for the integrated GPU means the comparison is defined entirely by the workstation card's recorded performance profile. The RTX 5880 Ada Generation's nearest rivals in the database are the NVIDIA RTX A2000 with an average score of 46,043 and a delta of -0.2%, the Intel Arc A730M at 45,592 with a delta of 0.8%, the AMD Radeon Pro 5500 XT at 45,384 with a delta of 1.3%, and the AMD Radeon RX 5600M at 46,601 with a delta of -1.4%. These figures show the RTX 5880 Ada Generation sits within a tight cluster of comparable workstation and mobile GPUs, with all deltas under 1.5%.

Where Each One Wins

The RTX 5880 Ada Generation wins every measurable category where data exists. Its shading unit count of 14,080, texture mapping units of 440, and render output units of 176 dwarf the Radeon 820M's 128 shading units, 8 TMUs, and 4 ROPs. The pixel rate of 433.0 GPixel/s and texture rate of 1,082.4 GTexel/s for the NVIDIA card are orders of magnitude above the Radeon 820M's 11.20 GPixel/s and 22.40 GTexel/s. Floating-point performance follows the same pattern: the RTX 5880 Ada Generation delivers 69.27 TFLOPS FP32 and the same value for FP16, while the Radeon 820M produces 716.8 GFLOPS for both FP32 and FP16.

Memory capacity and bandwidth show a similar divide. The RTX 5880 Ada Generation uses 48 GB of GDDR6 on a 384-bit bus with 864.0 GB/s of bandwidth. The Radeon 820M uses system-shared memory with a system-dependent bandwidth figure, and its memory clock is listed as system shared. The NVIDIA card's 110 ray tracing cores and 440 tensor cores provide dedicated acceleration for those workloads; the Radeon 820M has 2 ray tracing cores and no tensor cores recorded.

The Radeon 820M does hold advantages in certain physical and power characteristics. Its TDP is 15 W compared to the RTX 5880 Ada Generation's 285 W. It is an integrated graphics processor with no slot width and no power connectors, whereas the NVIDIA card is a dual-slot board requiring a single 16-pin power connector and a 600 W suggested power supply. The Radeon 820M uses a 4 nm process node from TSMC, while the RTX 5880 Ada Generation uses a 5 nm node. The AMD part's boost clock of 2800 MHz exceeds the NVIDIA card's boost clock of 2460 MHz, though the NVIDIA card has a higher base clock at 975 MHz versus 400 MHz.

The Verdict

The recorded data presents a clear split. The RTX 5880 Ada Generation is a workstation-class discrete GPU with substantial compute, memory, and rendering resources. Its average benchmark score of 45,972 and 85th percentile ranking confirm it operates at a high level among all GPUs in the database. The card's nearest rivals all score within 1.4% of its average, indicating it is competitively positioned against other professional and high-end mobile parts.

The AMD Radeon 820M has no benchmark scores in the database, no average score, and no nearest rivals. Its percentile ranking of 50 places it at the median of all GPUs, but this figure is not supported by any recorded test results. The hardware specifications suggest it is designed for low-power integrated use cases: 15 W TDP, system-shared memory, and a compact IGP form factor.

For workloads requiring 48 GB of VRAM, 864.0 GB/s of memory bandwidth, 69.27 TFLOPS of FP32 compute, and dedicated ray tracing and tensor cores, the RTX 5880 Ada Generation is the only option with recorded data supporting those capabilities. For systems constrained to 15 W of power, integrated graphics, and no additional power connectors, the Radeon 820M is the part that fits those physical parameters. The database contains no overlapping benchmark results, so any direct performance comparison between the two is unsupported by measurements.

Memory clocks are listed as system shared for the AMD part, while the NVIDIA card uses a 2250 MHz memory clock with 18 Gbps effective speed.

Physical and interface specifications diverge completely. The Radeon 820M is an integrated GPU with no slot width, no power connectors, and a PCIe 4.0 x8 bus interface. The RTX 5880 Ada Generation is a dual-slot, 267 mm (10.5 inches) long and 112 mm (4.4 inches) tall board with a PCIe 4.0 x16 interface, one 16-pin power connector, and four DisplayPort 1.4a outputs. The AMD part's display outputs are listed as portable device dependent. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Release dates and production status are recorded for both. The Radeon 820M launched on February 28, 2025, and is listed as active production with a predecessor of Navi II IGP. The RTX 5880 Ada Generation launched on January 4, 2024, is also active, and lists its predecessor as Workstation Ampere and successor as Blackwell PRO W. The NVIDIA card is assigned to the GeForce 50-series family, while the Radeon 820M has no series designation.
