Analysis: AMD Radeon 840M vs NVIDIA GeForce RTX 4070 AD103
Where Each One Wins
The AMD Radeon 840M and NVIDIA GeForce RTX 4070 AD103 occupy completely different segments of the graphics hardware spectrum. The Radeon 840M is an integrated graphics processor (IGP) built into the Krackan Point mobile chip, designed for power-conscious portable devices. The RTX 4070 AD103 is a discrete, dual-slot desktop graphics card from the GeForce 40-series, built for high-performance desktop workloads.
The Radeon 840M wins in power efficiency and system integration. Its 15 W TDP is dramatically lower than the RTX 4070 AD103's 200 W TDP. The IGP requires no power connectors, uses system-shared memory, and has no physical dimensions listed, as it is embedded into the processor package. It targets devices where portability and battery life take priority over raw performance.
The RTX 4070 AD103 wins in every performance category. It delivers 29.15 TFLOPS of FP32 compute versus 1,484.8 GFLOPS for the Radeon 840M. It has 12 GB of dedicated GDDR6X memory on a 192-bit bus with 504.2 GB/s bandwidth, while the Radeon 840M relies on system-shared memory with bandwidth that is system dependent. The RTX 4070 AD103 has 5,888 shading units, 184 texture mapping units, 64 raster operations units, 46 ray tracing cores, and 184 tensor cores. The Radeon 840M has 256 shading units, 16 TMUs, 8 ROPs, and 4 ray tracing cores.
The RTX 4070 AD103 is also the only one of the two with a dedicated tensor core count, making it suitable for AI-accelerated workloads. The Radeon 840M has no tensor cores listed. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature support is identical.
The RTX 4070 AD103 has a 240 mm length, 110 mm height, and 40 mm width, requiring a dual-slot cooling solution and a 16-pin power connector. The Radeon 840M is an IGP with no slot width, no power connectors, and display outputs that are portable device dependent.

Q: Are both GPUs still in production?
A: The Radeon 840M is listed as Active, with a release date of 2025-02-28. The RTX 4070 AD103 is listed as End-of-life, with a release date of 2024-02-29.
Head-to-Head Benchmarks
The recorded data contains no head-to-head benchmark results between these two GPUs. Neither GPU has any benchmark entries in the database, and both have an average benchmark score of zero. Both GPUs sit at the 50th percentile among all GPUs in the database's ranking system.
The absence of measured benchmark data means direct performance comparisons must be derived from the specification differences. The FP32 compute gap is the most pronounced: 29.15 TFLOPS versus 1,484.8 GFLOPS. This represents a 19.6x advantage for the RTX 4070 AD103. In pixel throughput, the RTX card achieves 158.4 GPixel/s against 23.20 GPixel/s for the Radeon 840M, a 6.8x difference. Texture rate shows 455.4 GTexel/s versus 46.40 GTexel/s, a 9.8x gap.
Memory bandwidth separates the two even further. The RTX 4070 AD103 provides 504.2 GB/s of dedicated bandwidth, while the Radeon 840M's bandwidth is classified as system dependent with no fixed value. The RTX card also has a fixed memory clock of 1313 MHz with 21 Gbps effective speed, whereas the Radeon uses system-shared memory with no specified clock.
The RTX 4070 AD103 has a higher base clock at 1920 MHz versus 400 MHz, but the Radeon 840M has a higher boost clock at 2900 MHz versus 2475 MHz. The Radeon's boost advantage does not compensate for its far lower shading unit count: 256 versus 5,888.
Specification Differences
The two GPUs differ in nearly every measurable specification. The Radeon 840M has 256 shading units, 16 TMUs, 8 ROPs, and 4 ray tracing cores. The RTX 4070 AD103 has 5,888 shading units, 184 TMUs, 64 ROPs, and 46 ray tracing cores. The RTX card also has 184 tensor cores, while the Radeon has none listed.
The process nodes differ: the Radeon uses 4 nm, the RTX card uses 5 nm. The RTX card has a known transistor count of 45,900 million and a die size of 379 mm², with a transistor density of 121.1M per mm². The Radeon's transistor count and die size are listed as unknown.
Memory configurations are fundamentally different. The Radeon uses system-shared memory with system-dependent bandwidth. The RTX card uses 12 GB of GDDR6X with a 192-bit bus and 504.2 GB/s bandwidth.
Power requirements diverge sharply. The Radeon has a 15 W TDP, no power connectors, and no suggested PSU. The RTX card has a 200 W TDP, a single 16-pin power connector, and a suggested 550 W PSU.
The bus interface differs: PCIe 4.0 x8 for the Radeon versus PCIe 4.0 x16 for the RTX card. Display outputs also differ: the Radeon's outputs are portable device dependent, while the RTX card provides 1x HDMI 2.1 and 3x DisplayPort 1.4a.
Physical dimensions apply only to the RTX card: 240 mm length, 110 mm height, 40 mm width, and dual-slot width. The Radeon is classified as an IGP with no dimensions.
