Architecture Differences

The AMD Radeon 840M and the NVIDIA RTX 5000 Mobile Ada Generation represent two fundamentally different approaches to mobile graphics. The Radeon 840M is an integrated graphics processor (IGP) built on the RDNA 3.5 architecture, fabricated on a 4 nm process at TSMC. Its chip is codenamed Krackan Point, and it belongs to the Navi III IGP generation under the Strix Point Mobile family. The RTX 5000 Mobile, in contrast, is a large discrete mobile GPU using the Ada Lovelace architecture, built on a 5 nm process at TSMC with the AD103 chip. The transistor counts tell a stark story: the RTX 5000 Mobile contains 45,900 million transistors on a 379 mm² die, while the Radeon 840M's transistor count and die size are recorded as unknown in the database.

The compute resource disparity is enormous. The Radeon 840M carries 256 shading units, 16 TMUs, and 8 ROPs, with 4 ray tracing cores and no tensor cores. The RTX 5000 Mobile fields 9,728 shading units, 304 TMUs, 112 ROPs, 76 ray tracing cores, and 304 tensor cores. This difference in raw execution resources explains the performance gap observed in the benchmark data. The Radeon 840M's RDNA 3.5 architecture includes ray tracing support, but with only 4 dedicated cores, its ray tracing throughput is structurally limited compared to the RTX 5000 Mobile's 76 RT cores.

Clock behavior also differs significantly. The Radeon 840M has a base clock of 400 MHz and a boost clock of 2,900 MHz, a very wide dynamic range typical of an integrated part that must scale aggressively to manage power within a shared thermal envelope. The RTX 5000 Mobile operates with a base clock of 1,425 MHz and a boost clock of 2,115 MHz, a narrower range with a higher floor, reflecting its dedicated power budget. The Radeon 840M's TDP is listed at 15 W, while the RTX 5000 Mobile's TDP is 120 W, an eightfold difference in power allocation.

The memory subsystem is another fundamental architectural split. The Radeon 840M uses system-shared memory, meaning its bandwidth and capacity are dependent on the host system's main memory configuration. The RTX 5000 Mobile has 16 GB of dedicated GDDR6 memory on a 256-bit bus, with 576.0 GB/s of bandwidth and a memory clock of 2250 MHz (18 Gbps effective). The bus interface also differs: the Radeon 840M uses PCIe 4.0 x8, while the RTX 5000 Mobile uses PCIe 4.0 x16. Both are marked as IGP slot width with no power connectors, and both are portable-device dependent for display outputs.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Radeon 840M and the NVIDIA RTX 5000 Mobile Ada Generation. The wins tally is 0 for each GPU. However, the recorded data for the RTX 5000 Mobile allows for meaningful positioning against its nearest rivals, which provides context for its performance level.

In the 3DMark Steel Nomad DX12 test, the RTX 5000 Mobile scores 3,596 points. Its nearest rival, the NVIDIA GeForce GT 545, scores 3,594 points, a delta of just 0.1%. This effectively places the two GPUs at parity, with the RTX 5000 Mobile holding a razor-thin edge. The next rival, the NVIDIA GeForce GT 735M, scores 3,616 points, which is 0.6% higher than the RTX 5000 Mobile. The NVIDIA GeForce GTX 1050 follows at 3,629 points, a 0.9% advantage over the RTX 5000 Mobile. The AMD Radeon HD 6770 rounds out the nearest rivals at 3,649 points, 1.5% ahead.

These deltas are remarkably small, all within a 1.5% band. The data indicates that the RTX 5000 Mobile sits at the 21st percentile among all GPUs in the database, meaning roughly four-fifths of recorded GPUs score higher. Its average benchmark score is 3,596, identical to its single Steel Nomad result.

For the Radeon 840M, there is no benchmark data to compare directly. Its percentile vs. all GPUs is listed at 50, but its average benchmark score is 0, and it has no nearest rivals defined. The database therefore cannot confirm any performance relationship between the two GPUs from recorded measurements. The architecture data, however, shows a 38x difference in shading units (9,728 vs. 256) and a 27.7x difference in FP32 throughput, as detailed in the specification comparison below.

The FP32 throughput difference is stark: the RTX 5000 Mobile delivers 41.15 TFLOPS compared to the Radeon 840M's 1,484.8 GFLOPS, which is roughly 27.7 times higher. The pixel rate difference is even more dramatic on a relative basis: 236.9 GPixel/s vs. 23.20 GPixel/s, a factor of about 10.2. The texture rate difference is approximately 13.9x, at 643.0 GTexel/s vs. 46.40 GTexel/s.

The release dates are separated by nearly two years, with the Radeon 840M launching on 2025-02-28 and the RTX 5000 Mobile on 2023-03-20. Both GPUs share the same API support (DirectX 12 Ultimate 12_2, OpenGL 4.6, Vulkan 1.4), the same foundry (TSMC), the same slot width (IGP), no power connectors, and portable-device-dependent display outputs.

The Verdict

The recorded data separates these two GPUs into distinct performance strata. The RTX 5000 Mobile Ada Generation has a measured 3DMark Steel Nomad DX12 score of 3,596 points, placing it at the 21st percentile among all GPUs. Its nearest rivals all sit within a 1.5% band, indicating a tightly clustered performance neighborhood. The Radeon 840M has no recorded benchmark scores in the database, so no direct measured comparison is possible.

The specification data, however, indicates that the RTX 5000 Mobile is the substantially larger and more capable processor. It carries 9,728 shading units, 304 TMUs, and 112 ROPs, versus the Radeon 840M's 256 shading units, 16 TMUs, and 8 ROPs. Its 16 GB of dedicated GDDR6 memory with 576.0 GB/s of bandwidth is a dedicated resource, whereas the Radeon 840M depends on system-shared memory with system-dependent bandwidth. The FP32 compute difference is approximately 27.7x in favor of the RTX 5000 Mobile.

The TDP figures reinforce this separation: 120 W for the RTX 5000 Mobile versus 15 W for the Radeon 840M. The RTX 5000 Mobile is designed for workloads that demand sustained high throughput, while the Radeon 840M is an integrated solution that shares power and thermal resources with the host processor. For applications that require maximum compute throughput, dedicated memory bandwidth, and extensive ray tracing resources, the RTX 5000 Mobile is the clear choice based on the data. For systems where a 15 W integrated GPU suffices and the host memory subsystem provides the necessary bandwidth, the Radeon 840M represents the integrated path. The database shows no benchmark overlap between them, so any performance comparison beyond the architectural specifications is not supported by recorded measurements.
