AMD Radeon 840M vs NVIDIA RTX 5000 Embedded Ada Generation Comparison

The Verdict

The data presents two fundamentally different mobile graphics solutions. The AMD Radeon 840M is an integrated processor graphics unit (IGP) built on the Krackan Point chip with RDNA 3.5 architecture, aimed at thin, low-power portable devices. The NVIDIA RTX 5000 Embedded Ada Generation is a discrete-class mobile workstation GPU based on the AD103 chip with Ada Lovelace architecture, designed for demanding professional workloads. Based strictly on the recorded specifications, the RTX 5000 Embedded Ada holds decisive advantages in nearly every compute and rendering metric, while the Radeon 840M offers a dramatically lower power envelope and a more recent release timeline. The verdict is clear: the RTX 5000 Embedded Ada is for users who need maximum graphics throughput, while the Radeon 840M suits systems where power consumption is the primary constraint.

The RTX 5000 Embedded Ada delivers 32.69 TFLOPS of FP32 performance versus 1,484.8 GFLOPS (1.4848 TFLOPS) for the Radeon 840M, a 22x gap in raw shader output. It also provides 16 GB of dedicated GDDR6 memory on a 256-bit bus with 576.0 GB/s bandwidth, versus the Radeon's system-shared memory with bandwidth described as system dependent. The pixel rate of 188.2 GPixel/s and texture rate of 510.7 GTexel/s for the RTX 5000 dwarf the Radeon's 23.20 GPixel/s and 46.40 GTexel/s. For any workload that stresses GPU compute, memory bandwidth, or rasterization throughput, the RTX 5000 Embedded Ada is the only viable choice from this data.

The Radeon 840M, however, operates at a 15 W TDP, which is one-eighth of the RTX 5000's 120 W TDP. It also has a higher boost clock at 2900 MHz versus 1680 MHz, and a smaller 4 nm process node versus 5 nm. This makes it suitable for fanless or ultraportable designs where the RTX 5000 cannot physically fit or be cooled. The Radeon also has a newer release date in the database: 2025-02-28 versus 2023-03-20 for the RTX 5000.

Where Each One Wins

The RTX 5000 Embedded Ada Generation wins in every category that involves raw graphics processing capability. Its 9,728 shading units, 304 texture mapping units, and 112 ROPs provide the hardware resources needed for high-resolution rendering, complex geometry, and heavy pixel fill. The 76 RT cores and 304 tensor cores add dedicated hardware for ray tracing and AI-accelerated workloads, features the Radeon 840M lacks entirely, as its tensor core count is listed as null. The 576.0 GB/s memory bandwidth is essential for large datasets, high-resolution textures, and compute-heavy tasks such as machine learning inference. The RTX 5000 also uses a wider PCIe 4.0 x16 interface versus the Radeon's PCIe 4.0 x8, allowing faster host-device data transfers.

The Radeon 840M wins in power efficiency and integration. Its 15 W TDP makes it suitable for compact, battery-powered devices where the 120 W TDP of the RTX 5000 would be prohibitive. The Radeon's 4 nm process node (TSMC) versus the RTX 5000's 5 nm process node gives it a manufacturing advantage in transistor density, though the RTX 5000 compensates with a massive die (379 mm² and 45,900 million transistors). The Radeon's 400 MHz base clock and 2900 MHz boost clock show a wider dynamic range, allowing it to idle lower and boost higher relative to its power budget. For integrated graphics, the Radeon 840M's specifications are competitive within its class, but the data shows no scenario where it outperforms the RTX 5000 in absolute graphics throughput.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The AMD Radeon 840M uses RDNA 3.5 architecture on the Krackan Point chip, manufactured on a 4 nm process at TSMC. It belongs to the Navi III IGP generation (Strix Point Mobile), succeeding the Navi II IGP. The NVIDIA RTX 5000 Embedded Ada Generation uses Ada Lovelace architecture on the AD103 chip, manufactured on a 5 nm process, also at TSMC. It belongs to the Ada-MW generation, succeeding Ampere-MW and preceding Blackwell-MW.

The transistor counts and die sizes differ substantially. The RTX 5000 has 45,900 million transistors on a 379 mm² die, yielding a density of 121.1M per mm². The Radeon 840M's transistor count and die size are listed as unknown, so a direct density comparison is not possible from the data. The RTX 5000's larger die accommodates 9,728 shading units, 304 TMUs, 112 ROPs, 76 RT cores, and 304 tensor cores. The Radeon 840M has 256 shading units, 16 TMUs, 8 ROPs, and 4 RT cores, with no tensor cores.

Clock behavior also differs. The Radeon 840M has a base clock of 400 MHz and a boost clock of 2900 MHz. The RTX 5000 has a base clock of 930 MHz and a boost clock of 1680 MHz. The Radeon's lower base clock and higher boost suggest aggressive power management for an integrated part, while the RTX 5000 maintains a higher floor and a more modest boost ceiling, likely due to thermal and power constraints in a 120 W envelope. Memory architecture is completely different: the Radeon uses system-shared memory, while the RTX 5000 uses 16 GB of dedicated GDDR6 on a 256-bit bus.

Head-to-Head Benchmarks

The recorded data contains no direct benchmark scores for either GPU, and the head-to-head benchmark list is empty. Both GPUs hold a 50th percentile ranking against all GPUs in the database, with an average benchmark score of 0. This means the quantitative comparison must rely entirely on the specification sheet differences.

The most significant performance gap appears in FP32 throughput. The RTX 5000's 32.69 TFLOPS is 22x the Radeon 840M's 1,484.8 GFLOPS. In texture fill rate, the RTX 5000 achieves 510.7 GTexel/s versus 46.40 GTexel/s for the Radeon, an 11x advantage. Pixel fill rate shows a similar pattern: 188.2 GPixel/s versus 23.20 GPixel/s, an 8.1x difference. Memory bandwidth is the largest ratio: 576.0 GB/s versus system dependent, meaning the Radeon's bandwidth is not even quantified in the database.

The RTX 5000's advantage in shading units (9,728 versus 256), TMUs (304 versus 16), and ROPs (112 versus 8) provides the hardware basis for these ratios. The RT core count difference (76 versus 4) indicates a 19x gap in dedicated ray tracing hardware. The tensor core count of 304 on the RTX 5000 versus null on the Radeon means AI acceleration is exclusively available on the NVIDIA part.

The Radeon 840M does hold one notable clock advantage: its boost clock of 2900 MHz exceeds the RTX 5000's 1680 MHz by 72.6%. However, given the massive difference in shader count, this higher clock cannot compensate for the 38x difference in shading units. The Radeon's lower base clock of 400 MHz versus 930 MHz further suggests it spends more time at low power states.

Both GPUs share identical API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both use PCIe 4.0, though the RTX 5000 has a x16 interface versus the Radeon's x8. Both are listed as Active production status, and both have no launch MSRP recorded in the database.
