AMD Radeon 840M vs NVIDIA RTX 5880 Ada Generation Comparison

The Verdict

The recorded data places these two GPUs at opposite ends of the performance spectrum. The AMD Radeon 840M is an integrated processor graphics solution in the 50th percentile of all GPUs, designed for mobility and low power draw. The NVIDIA RTX 5880 Ada Generation sits in the 85th percentile, a dual-slot workstation accelerator aimed at professional compute and rendering workloads. The benchmark data shows the RTX 5880 delivers an average benchmark score of 45,972, while the Radeon 840M has no recorded benchmark scores in the database, making direct numerical comparison impossible. The data indicates the RTX 5880 is the clear choice for any workload requiring substantial graphics processing power, while the 840M serves systems where integrated graphics and minimal power consumption are the priorities.

Architecture Differences

The two GPUs come from different manufacturers and use entirely different architectures. AMD builds the Radeon 840M on the Krackan Point chip using RDNA 3.5 architecture, manufactured on a 4 nm process at TSMC. It belongs to the Navi III IGP generation for Strix Point Mobile. The transistor count and die size are unknown in the database. NVIDIA's RTX 5880 Ada Generation uses the AD102 chip with Ada Lovelace architecture, built on a 5 nm process, also at TSMC. Its transistor count is recorded as 76,300 million and the die size is 609 mm², giving a transistor density of 125.3M per mm².

The RTX 5880 uses discrete GDDR6 memory with 48 GB capacity, a 384 bit bus, and 864.0 GB/s bandwidth. The Radeon 840M uses system shared memory, with the bus width and bandwidth listed as system dependent. The RTX 5880 has 14,080 shading units, 440 texture mapping units, and 176 raster output pipelines. It also includes 110 ray tracing cores and 440 tensor cores. The Radeon 840M has 256 shading units, 16 TMUs, 8 ROPs, and 4 ray tracing cores. The 840M has no tensor cores listed in the database.

Where Each One Wins

The RTX 5880 Ada Generation wins in every measurable metric recorded in the database. Its 69.27 TFLOPS FP32 performance dwarfs the 840M's 1,484.8 GFLOPS. The pixel rate of 433.0 GPixel/s versus 23.20 GPixel/s shows a massive fill rate advantage. Texture rate of 1,082.4 GTexel/s versus 46.40 GTexel/s confirms the same pattern. The 48 GB GDDR6 memory with 864.0 GB/s bandwidth provides a professional workstation class memory subsystem, while the 840M relies on system shared memory. The RTX 5880 also has 440 tensor cores, which the 840M lacks entirely, making the NVIDIA card suitable for AI and compute workloads that require tensor operations.

The Radeon 840M wins in power efficiency and physical integration. Its 15 W TDP is dramatically lower than the RTX 5880's 285 W. It requires no power connectors and fits as an IGP in portable devices, whereas the RTX 5880 is a dual-slot card with a 267 mm length and a 16-pin power connector. The 840M also has a higher boost clock at 2900 MHz versus 2460 MHz, though this does not translate into higher performance given the massive core count difference. The 840M uses a smaller 4 nm process node compared to the 5 nm node of the RTX 5880, which contributes to its low power draw.

The RTX 5880's nearest rivals in the database include the NVIDIA RTX A2000 at 46,043 average score, the Intel Arc A730M at 45,592, the AMD Radeon Pro 5500 XT at 45,384, and the AMD Radeon RX 5600M at 46,601. The RTX 5880's score of 45,972 places it in the middle of this cluster, slightly behind the RTX A2000 and RX 5600M, slightly ahead of the Arc A730M and Pro 5500 XT. This positioning suggests the RTX 5880 competes in the same performance tier as these workstation and high-end mobile GPUs.

The Radeon 840M's 50th percentile ranking among all GPUs and absence of benchmark scores indicate it targets basic graphics duties in thin-and-light laptops. Its 4 ray tracing cores and DirectX 12 Ultimate support provide modern API compatibility, but the hardware resources are minimal. The 840M's system shared memory architecture means performance scales with the host system's memory configuration, making it a flexible but modest solution.

For users requiring professional rendering, AI acceleration, or high-resolution compute workloads, the benchmark data points exclusively to the RTX 5880. For portable systems prioritizing low power consumption and integrated graphics, the Radeon 840M fits that role. The two GPUs serve entirely different market segments, with the RTX 5880 delivering workstation class performance in every recorded category and the 840M offering an efficient integrated alternative.
