AMD Radeon 840M vs NVIDIA GeForce RTX 5070 Mobile Comparison

Where Each One Wins

The recorded data shows a stark asymmetry between these two mobile graphics solutions. The AMD Radeon 840M has no benchmark entries in the database, while the NVIDIA GeForce RTX 5070 Mobile carries nine recorded test scores. This means the use-case split is defined entirely by what the NVIDIA part can demonstrate and what the AMD IGP cannot currently substantiate with measured results.

For the RTX 5070 Mobile, the wins span compute, legacy API performance, and modern graphics workloads. Its Geekbench OpenCL score of 122,238 and Vulkan score of 116,960 indicate strong general-purpose compute and modern API utilization. The PassMark suite shows a distinct pattern: DirectX 9 scores 214, DirectX 10 scores 129, DirectX 11 scores 192, and DirectX 12 scores 93. The G2D score of 896 covers 2D operations, while the G3D score of 20,355 represents the overall 3D graphics workload. GPU compute adds 8,279.

The AMD Radeon 840M, by contrast, has zero recorded benchmarks. Its percentile rank of 50 places it at the median of all GPUs in the database, but without any actual test scores, the database cannot assign it wins in any category. The RTX 5070 Mobile sits at the 75th percentile, meaning it outperforms roughly three-quarters of all recorded GPUs. The practical implication is that any use case requiring measured performance data currently points exclusively to the NVIDIA part.

Architecture Differences

The two chips come from different design philosophies and process nodes. The AMD Radeon 840M uses the Krackan Point chip built on RDNA 3.5 architecture, fabricated on a 4 nm TSMC process. It belongs to the Navi III IGP generation for Strix Point Mobile. The NVIDIA GeForce RTX 5070 Mobile uses the GB206 chip on Blackwell 2.0 architecture, fabricated on a 5 nm TSMC process, and belongs to the GeForce 50 Mobile generation.

The transistor counts differ dramatically. The RTX 5070 Mobile packs 21,900 million transistors on a 181 mm² die, yielding a density of 121.0 million transistors per square millimeter. The Radeon 840M lists its transistor count and die size as unknown, so no direct density comparison is possible from the data.

Compute resources diverge sharply. The Radeon 840M has 256 shading units, 16 texture mapping units, 8 raster output pipelines, and 4 ray tracing cores. The RTX 5070 Mobile has 4,608 shading units, 144 TMUs, 48 ROPs, 36 RT cores, and 144 tensor cores. The NVIDIA part also has tensor cores, which the AMD IGP does not list at all.

Memory architecture is fundamentally different. The AMD Radeon 840M uses system shared memory with a system-dependent bus width and bandwidth. The RTX 5070 Mobile has dedicated 8 GB of GDDR7 memory on a 128-bit bus, delivering 384.0 GB/s of bandwidth. This dedicated memory arrangement gives the NVIDIA part a substantial resource advantage for graphics-heavy workloads.

Clock behavior also differs. The Radeon 840M has a base clock of 400 MHz and a boost clock of 2,900 MHz. The RTX 5070 Mobile has a base clock of 907 MHz, a boost of 1,425 MHz, and a memory clock of 1,500 MHz with 24 Gbps effective transfer. The AMD part boosts much higher, but with far fewer compute units.

The bus interface differs as well: the Radeon 840M uses PCIe 4.0 x8, while the RTX 5070 Mobile uses PCIe 5.0 x16. Both are listed as IGP slot width with no power connectors and portable device dependent display outputs. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for this pair, and the AMD Radeon 840M has no individual benchmark scores. The only measurable data comes from the RTX 5070 Mobile. Its average benchmark score is 29,928, calculated from the nine recorded tests. That average places it 0.1% behind the NVIDIA GeForce RTX 3070 Ti, which averages 29,945, and 0.5% ahead of the NVIDIA GeForce RTX 2080 Ti at 29,783. Against AMD desktop parts, it sits 0.6% behind the Radeon RX 6800 at 30,095 and 1.7% behind the Radeon RX 6700 at 30,433.

The PassMark G3D score of 20,355 is the single largest contributor to that average, representing the primary 3D graphics benchmark. The Geekbench OpenCL score of 122,238 and Vulkan score of 116,960 are large numbers that reflect compute capability. The GPU compute score of 8,279 from PassMark provides a separate compute measurement. The 2D score of 896 is comparatively small, as expected for a 2D workload.

The legacy API scores tell an interesting story. DirectX 9 scores 214, which is the highest of the DirectX tests. DirectX 10 scores 129, DirectX 11 scores 192, and DirectX 12 scores 93. The pattern suggests that the RTX 5070 Mobile handles older DirectX 9 workloads relatively well, while DirectX 12 performance appears lower in raw PassMark terms. However, without AMD data, no relative comparison is possible.

Since the Radeon 840M has no recorded scores, the database cannot quantify any win for it. The RTX 5070 Mobile wins every measurable category by default, but that is a function of data availability rather than demonstrated superiority in each specific test. The percentile difference reinforces the gap: the AMD part is at the 50th percentile, and the NVIDIA part is at the 75th percentile.

The Verdict

The data supports a clear choice for anyone requiring measured performance. The NVIDIA GeForce RTX 5070 Mobile delivers 29,928 average benchmark score across nine tests, covering compute, 2D, 3D, and multiple DirectX versions. Its 75th percentile ranking places it above the median in the database, and its nearest rivals are desktop-class GPUs like the RTX 3070 Ti and Radeon RX 6800, with deltas under 2%.

The AMD Radeon 840M has no benchmark scores, a 50th percentile ranking, and a specification sheet that shows far fewer compute resources. Its 256 shading units, 16 TMUs, and 8 ROPs contrast with 4,608 shading units, 144 TMUs, and 48 ROPs on the NVIDIA part. The FP32 compute difference is approximately 8.8x in favor of NVIDIA, and the memory system is dedicated versus shared.

The RTX 5070 Mobile also carries tensor cores, 144 of them, which the AMD part does not list. The 36 RT cores versus 4 RT cores indicates a substantial difference in ray tracing capability. The 384.0 GB/s memory bandwidth versus system-dependent bandwidth further separates the two in memory-intensive workloads.

The AMD part does have advantages in the specification sheet. Its boost clock of 2,900 MHz exceeds the NVIDIA boost of 1,425 MHz. Its TDP of 15 W is one-third of the NVIDIA 50 W TDP. Its 4 nm process node is smaller than the 5 nm node used by NVIDIA. These factors suggest lower power consumption and potentially better efficiency in light workloads, but the database contains no benchmarks to confirm actual performance at those settings.

The release timing shows the AMD part arrived earlier, on 2025-02-28, versus 2025-04-14 for NVIDIA. Neither part has a launch MSRP recorded, and neither has a successor listed. Both are active production parts.

The verdict from the recorded data is straightforward: the NVIDIA GeForce RTX 5070 Mobile is the only one of the two with measurable performance, and that performance is competitive with high-end desktop GPUs from prior generations. The AMD Radeon 840M, based on its specifications, targets a different class of workload, likely integrated graphics in low-power portable devices, but the database cannot confirm any performance claims without benchmark entries. For any use case where benchmark scores matter, the RTX 5070 Mobile is the only option with data to support it.
