AMD Radeon 840M vs NVIDIA GeForce RTX 4070 Ti Comparison

AMD Radeon 840M is an integrated graphics processor from AMD, built on the RDNA 3.5 architecture and using the Krackan Point chip. NVIDIA GeForce RTX 4070 Ti is a discrete add-in board from NVIDIA, based on the Ada Lovelace architecture with the AD104 chip. The database shows these two products occupy completely different segments of the GPU landscape, with the RTX 4070 Ti recording an average benchmark score of 44,795 and sitting at the 84th percentile of all GPUs, while the Radeon 840M has no recorded benchmark scores and a 50th percentile placement. This comparison highlights the structural differences between an IGP designed for low-power mobile systems and a high-end discrete card aimed at desktop performance.

The Verdict

The data indicates a clear split in intended use cases. The AMD Radeon 840M is an integrated solution with a 15 W TDP, designed to share system memory and rely on the host device's cooling and power delivery. Its production status is Active, and it was released on February 28, 2025, making it a current-generation IGP for portable devices. The NVIDIA GeForce RTX 4070 Ti, in contrast, is an end-of-life product with a 285 W TDP, a dual-slot footprint, a 600 W suggested power supply, and a 16-pin power connector. It carries a launch MSRP of 799 USD, a figure that reflects its discrete, high-performance positioning.

Benchmark results place the RTX 4070 Ti in the upper tier of GPUs. Its nearest rivals in the database include the NVIDIA GeForce RTX 5090 Mobile at 45,152 points (0.8% ahead), the AMD Radeon Pro 5500 XT at 45,384 points (1.3% ahead), the Intel Arc A730M at 45,592 points (1.7% ahead), and the NVIDIA RTX A6000 at 44,075 points (1.6% behind). These deltas are all within roughly two percent, indicating the RTX 4070 Ti sits in a tightly contested performance band among its recorded peers. For the Radeon 840M, no such comparisons exist in the database, as it has zero benchmark entries and an average score of zero.

The choice between these two hinges on the platform. The Radeon 840M is the only option for a system where the GPU is integrated into the processor, drawing from shared system memory and consuming minimal power. The RTX 4070 Ti is the only option for a desktop build requiring a dedicated card with its own 12 GB of GDDR6X memory on a 192-bit bus. The data does not support a direct performance comparison, as the IGP has no recorded scores, but the architectural and specification gaps are substantial.

Architecture Differences

The Radeon 840M is built on the RDNA 3.5 architecture, which represents AMD's integrated graphics design for the Navi III IGP generation, specifically the Krackan Point chip. This architecture is fabricated on a 4 nm process at TSMC, reflecting a newer manufacturing node compared to the RTX 4070 Ti's 5 nm process. The IGP nature of the Radeon 840M means it shares system memory and has no dedicated VRAM, with its memory bandwidth being System Dependent on the host platform.

The RTX 4070 Ti uses the Ada Lovelace architecture, which is NVIDIA's dedicated GPU design for the GeForce 40 series. It is built on the AD104 chip with 35,800 million transistors on a 294 mm² die, achieving a transistor density of 121.8M per mm². This discrete card features its own 12 GB of GDDR6X memory with a 192-bit interface. The architecture includes 60 ray tracing cores and 240 tensor cores, enabling dedicated hardware for ray tracing and AI workloads. The Radeon 840M, by contrast, has only 4 ray tracing cores and no tensor cores, indicating a more limited feature set for those specialized tasks.

The API support is identical between the two: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. However, the underlying hardware capabilities differ substantially. The RTX 4070 Ti's 7,680 shading units and 240 TMUs provide a massive parallel compute capability, while the Radeon 840M's 256 shading units and 16 TMUs are a fraction of that scale. The Radeon 840M's boost clock of 2,900 MHz is higher than the RTX 4070 Ti's 2,610 MHz boost, but the raw unit counts dominate the performance equation.

Specification Differences

The database records several distinct specification differences between the two products. The Radeon 840M has a base clock of 400 MHz and a boost clock of 2,900 MHz, while the RTX 4070 Ti has a base clock of 2,310 MHz and a boost clock of 2,610 MHz. Memory configurations diverge completely: the Radeon 840M uses System Shared memory with System Dependent bandwidth, whereas the RTX 4070 Ti uses 12 GB of GDDR6X on a 192-bit bus with 504.2 GB/s bandwidth.

Compute resources show a 30-fold difference in shading units (256 vs 7,680), a 15-fold difference in TMUs (16 vs 240), and a 10-fold difference in ROPs (8 vs 80). The pixel rate of the RTX 4070 Ti is 208.8 GPixel/s compared to 23.20 GPixel/s for the Radeon 840M, and the texture rate is 626.4 GTexel/s versus 46.40 GTexel/s. FP32 performance is 40.09 TFLOPS for the RTX 4070 Ti versus 1,484.8 GFLOPS for the Radeon 840M, with both having a 1:1 FP16 ratio.

Power and physical specifications differ entirely. The Radeon 840M has a 15 W TDP, is an IGP with no power connectors, and uses a PCIe 4.0 x8 interface. The RTX 4070 Ti has a 285 W TDP, is dual-slot, requires a 1x 16-pin power connector, a 600 W suggested PSU, and uses a PCIe 4.0 x16 interface. The RTX 4070 Ti measures 285 mm in length, 112 mm in height, and 42 mm in width, while the Radeon 840M has no physical dimensions listed. The RTX 4070 Ti's display outputs are 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the Radeon 840M's outputs are listed as Portable Device Dependent.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two products, and the Radeon 840M has no individual benchmark scores recorded. The RTX 4070 Ti, however, has a full suite of benchmark results. Its 3DMark Steel Nomad DX12 score is 5,024, which places it in a competitive position among its nearest recorded rivals. The Geekbench OpenCL score of 176,953 and Vulkan score of 213,808 show strong compute performance in those cross-platform tests.

In Passmark tests, the RTX 4070 Ti scores 31,624 in G3D and 18,396 in GPU Compute. Its DirectX 9 score is 352, DirectX 10 is 187, DirectX 11 is 288, and DirectX 12 is 116. The G2D score is 1,200. These figures provide a complete picture of the RTX 4070 Ti's performance across various APIs and workloads.

The Radeon 840M's lack of benchmark data means no direct comparison can be made. The database lists its percentile against all GPUs as 50, but with an average benchmark score of zero, this percentile likely reflects its position as a mid-range IGP rather than a measured performance score. The RTX 4070 Ti's 84th percentile is based on its 44,795 average score, which places it among the top tier of recorded GPUs.

Where Each One Wins

The RTX 4070 Ti wins decisively in every measurable performance dimension recorded in the database. Its 40.09 TFLOPS FP32 performance is 27 times higher than the Radeon 840M's 1,484.8 GFLOPS. Its 504.2 GB/s memory bandwidth is a dedicated, fixed resource, whereas the Radeon 840M's bandwidth is System Dependent and shared with the CPU. The RTX 4070 Ti's 60 ray tracing cores and 240 tensor cores provide hardware acceleration for ray tracing and AI workloads, capabilities that the Radeon 840M either lacks entirely (tensor cores) or has in minimal form (4 ray tracing cores).

The Radeon 840M wins in power efficiency and integration. Its 15 W TDP is 270 W lower than the RTX 4070 Ti's 285 W TDP, making it suitable for portable devices where power draw and heat dissipation are critical constraints. Its PCIe 4.0 x8 interface and lack of power connectors reflect its role as an integrated component, requiring no additional cabling or power supply headroom. The Radeon 840M's newer release date (February 28, 2025) and Active production status indicate ongoing availability for current mobile platforms, while the RTX 4070 Ti is End-of-life with a successor already listed.

The use-case split is clear. The Radeon 840M serves systems where a discrete GPU is impossible or undesirable, such as thin-and-light laptops or compact devices, prioritizing low power consumption and simplicity. The RTX 4070 Ti serves desktop builds where maximum compute throughput, dedicated memory, and advanced features like ray tracing are required, accepting high power draw and physical size. The data does not suggest any overlap: the RTX 4070 Ti's benchmark scores and architectural resources place it in a performance class that the Radeon 840M's hardware configuration cannot approach, while the Radeon 840M's integrated design offers a platform flexibility that a dual-slot, 285 W card cannot match.
