AMD Radeon 840M vs NVIDIA GeForce RTX 5070 Comparison

Where Each One Wins

The AMD Radeon 840M and the NVIDIA GeForce RTX 5070 occupy completely different segments of the graphics market, and the recorded data confirms that each delivers wins in entirely separate use cases. The RTX 5070 wins every single measurable benchmark category where both products could be evaluated, but the 840M is not designed to compete on raw performance. The 840M is an integrated graphics processor (IGP) with a 15 W thermal design power, built for portable devices where power efficiency and space are the primary constraints. The RTX 5070 is a dual-slot discrete graphics card with a 250 W TDP, a 600 W suggested power supply, and a 245 mm physical length, aimed squarely at desktop gaming and high-performance compute workloads.

The data shows that the RTX 5070 dominates in every compute and graphics test recorded in the database. Its PassMark G3D score of 29,137 dwarfs anything an integrated solution could produce, and its Geekbench OpenCL score of 172,660 indicates massive compute throughput. The 840M, by contrast, has no recorded benchmark scores in the database, which means its wins are not measured in frame rates or synthetic scores but in its physical and electrical footprint. The 840M wins in portability, power draw, and system integration. It requires no power connectors, occupies no expansion slot, and uses system shared memory, making it suitable for thin-and-light laptops where a discrete GPU cannot physically fit.

The RTX 5070 wins in memory bandwidth by an enormous margin. It has 12 GB of dedicated GDDR7 memory on a 192 bit bus with 672.0 GB/s of bandwidth. The 840M uses system shared memory with bandwidth described as system dependent, meaning its performance scales with the host system's memory configuration rather than a dedicated VRAM pool. For gaming at high resolutions or for workloads that require large datasets to reside in fast memory, the RTX 5070 is the clear winner. For basic display output, office productivity, and light media acceleration in a portable device, the 840M provides the necessary functionality without the power and space demands of a discrete card.

The RTX 5070 also wins decisively in the API feature set comparison. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the feature-level API support is identical. However, the RTX 5070 has 48 ray tracing cores and 192 tensor cores, while the 840M has only 4 ray tracing cores and no tensor cores listed in the database. Any workload that relies on hardware-accelerated ray tracing or tensor operations, such as DLSS-style upscaling or AI inference, will perform substantially better on the RTX 5070. The 840M's 4 ray tracing cores are present but the hardware resources are minimal compared to the discrete card.

The Verdict

The data supports a clear verdict: the RTX 5070 is the superior product for any application that demands high graphics performance, and the 840M is the appropriate choice only for ultra-portable systems where the discrete card cannot be installed. The RTX 5070 sits at the 82nd percentile among all GPUs in the database, while the 840M sits at the 50th percentile. That percentile gap alone indicates that the RTX 5070 outperforms the vast majority of graphics hardware in the database, while the 840M sits exactly at the median, a position consistent with a modest integrated solution.

The RTX 5070's average benchmark score of 40,377 places it in the company of professional workstation cards. Its nearest rivals in the database are the AMD Radeon Pro 580 with an average score of 40,318 and a delta of 0.1%, the AMD Radeon Pro WX 7100 with 40,063 and a delta of 0.8%, and the AMD Radeon Pro 5300 with 40,870 and a delta of -1.2%. These deltas show the RTX 5070 performing within roughly 1% of established workstation GPUs, confirming that it delivers professional-grade compute capability in a consumer gaming card. The NVIDIA RTX A500 Mobile trails by 2%, further situating the RTX 5070 in a performance class far above entry-level or integrated graphics.

For a user building a desktop system with space for a 245 mm long, dual-slot card and a 600 W power supply, the RTX 5070 is the only rational choice between these two. For a user purchasing a thin-and-light laptop where the 840M is integrated into the processor, the discrete GPU is not an option at all, so the 840M wins by default in that form factor. The records show no head-to-head benchmark results between these two products, which makes direct comparison impossible, but the specification sheet alone settles the question. The RTX 5070 has 6,144 shading units versus 256 for the 840M, 192 texture mapping units versus 16, and 80 render output units versus 8. The arithmetic advantage is overwhelming.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for this pairing, and the 840M has no individual benchmark scores recorded. The RTX 5070, however, has a full set of ten recorded benchmark results that define its performance profile. Its highest single-test score is the Geekbench Vulkan result of 178,923, followed closely by the Geekbench OpenCL score of 172,660. These two results indicate that the card excels in both graphics and general-purpose compute workloads when accessed through modern APIs.

In the PassMark suite, the RTX 5070 shows a varied profile across DirectX versions. The DirectX 9 score of 320 and the DirectX 11 score of 277 are notably higher than the DirectX 12 score of 108, which may reflect driver optimization patterns or the specific workload characteristics of each test. The DirectX 10 score of 180 sits between these values. The PassMark G3D score of 29,137 is the overall graphics mark, and the GPU compute score of 15,787 indicates strong compute throughput. The G2D score of 1,305 covers 2D graphics operations, which are typically not the primary strength of high-performance gaming cards.

The 3DMark Steel Nomad DX12 score of 5,077 provides a modern DirectX 12 gaming workload result. This test is significant because it represents the current generation of gaming graphics demands. The RTX 5070's score here, combined with its 82nd percentile ranking, confirms that it handles contemporary gaming loads well. The 840M has no comparable recorded score, so any quantitative comparison of gaming performance between the two is impossible from the available data. What can be stated is that the RTX 5070's raw specifications, particularly its 30.87 TFLOPS of FP32 compute and 672.0 GB/s of memory bandwidth, place it in a performance tier that the 840M's 1,484.8 GFLOPS and system-dependent shared memory cannot approach.

Architecture Differences

The two GPUs come from different manufacturers and use fundamentally different architectures. The AMD Radeon 840M uses the RDNA 3.5 architecture on the Krackan Point chip, fabricated on a 4 nm process at TSMC. It belongs to the Navi III IGP generation for Strix Point Mobile, indicating its role as an integrated processor for mobile platforms. The RTX 5070 uses the Blackwell 2.0 architecture on the GB205 chip, fabricated on a 5 nm process, also at TSMC. It belongs to the GeForce 50 generation and has a predecessor in the GeForce 40 series and a successor in the GeForce 60 series.

The RTX 5070 has a transistor count of 31,100 million on a die size of 263 mm², giving it a transistor density of 118.3 million transistors per square millimeter. The 840M's transistor count and die size are listed as unknown in the database, so no direct comparison of silicon complexity is possible. The process node difference is notable: the 840M uses a 4 nm process while the RTX 5070 uses a 5 nm process, meaning the integrated GPU uses a slightly more advanced fabrication node despite its far smaller scale.

The ray tracing and tensor core counts represent the most significant architectural divergence. The RTX 5070 has 48 ray tracing cores and 192 tensor cores, enabling hardware-accelerated ray tracing and AI-based tensor operations. The 840M has 4 ray tracing cores and no tensor cores, which limits its capability in these workloads. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the software API surface is identical. The bus interface also differs: the 840M uses PCIe 4.0 x8 while the RTX 5070 uses PCIe 5.0 x16, giving the discrete card twice the lane count and a newer bus generation.

Specification Differences

The specification sheets reveal a product positioned at opposite ends of the graphics spectrum. The RTX 5070 has a base clock of 2,325 MHz and a boost clock of 2,512 MHz, while the 840M has a base clock of 400 MHz and a boost clock of 2,900 MHz. The 840M's boost clock is actually higher than the RTX 5070's boost clock, but this does not compensate for the enormous differences in shading units, memory bandwidth, and power envelope.

The FP32 compute figures illustrate the performance gap clearly. The RTX 5070 delivers 30.87 TFLOPS of FP32 performance, while the 840M delivers 1,484.8 GFLOPS. Both support FP16 at a 1:1 ratio with FP32. The pixel rate for the RTX 5070 is 201.0 GPixel/s versus 23.20 GPixel/s for the 840M, and the texture rate is 482.3 GTexel/s versus 46.40 GTexel/s. The RTX 5070's memory runs at 1,750 MHz with 28 Gbps effective speed, while the 840M's memory clock is listed as system shared, confirming that its memory performance depends entirely on the host system.

The RTX 5070 has a launch MSRP of 549 USD, a 250 W TDP, a dual-slot form factor, a 600 W suggested power supply, and display outputs of 1x HDMI 2.1b and 3x DisplayPort 2.1b. The 840M has no launch MSRP, a 15 W TDP, an IGP slot width, no power connectors, no suggested PSU, and display outputs described as portable device dependent. The RTX 5070 measures 245 mm by 115 mm by 40 mm, while the 840M has no listed dimensions because it is integrated into the processor. The 840M was released on February 28, 2025, and the RTX 5070 followed on March 3, 2025, a difference of three days. Both are listed as active in production status.
