AMD Radeon 840M vs NVIDIA GeForce RTX 4070 SUPER Comparison

Head-to-Head Benchmarks

The AMD Radeon 840M and NVIDIA GeForce RTX 4070 SUPER occupy entirely different segments of the graphics market, and the recorded data reflects a decisive performance gap. The GeForce RTX 4070 SUPER, with an average benchmark score of 43,223, sits in the 83rd percentile among all GPUs in the database. The Radeon 840M, by contrast, registers at the 50th percentile with an average benchmark score of 0, meaning no benchmark results are recorded for the integrated part. This absence of recorded scores for the 840M makes direct numerical comparisons impossible for individual tests, but the architectural specifications provide a clear picture of the performance chasm.

The RTX 4070 SUPER delivers 35.48 TFLOPS of FP32 compute, while the Radeon 840M delivers 1,484.8 GFLOPS, which converts to approximately 1.48 TFLOPS. That places the NVIDIA part at roughly 24 times the raw floating-point throughput of the AMD integrated graphics. In texture fill rate, the RTX 4070 SUPER reaches 554.4 GTexel/s versus 46.40 GTexel/s for the 840M, a margin of nearly 12 times. Pixel throughput shows a similar story: 198.0 GPixel/s for the RTX 4070 SUPER against 23.20 GPixel/s for the Radeon 840M, a factor of roughly 8.5.

Memory bandwidth amplifies the disparity further. The GeForce RTX 4070 SUPER uses 12 GB of GDDR6X on a 192-bit bus, delivering 504.2 GB/s of bandwidth. The Radeon 840M relies on system-shared memory with bandwidth described as system dependent, meaning its effective throughput varies by platform and cannot match a dedicated memory subsystem. Clock speeds also differ substantially: the RTX 4070 SUPER boosts to 2475 MHz from a 1980 MHz base, while the Radeon 840M boosts to 2900 MHz from a 400 MHz base. Despite the AMD part's higher boost clock, its smaller execution resource pool prevents it from approaching the NVIDIA card's output.

The RTX 4070 SUPER's nearest rivals in the database confirm its standing. Its average score of 43,223 sits within 0.1 percent of the NVIDIA Quadro M6000 24 GB (43,262) and the NVIDIA GeForce RTX 5050 Mobile (43,268). It trails the RTX 4090 Mobile (43,667) by 1 percent. These narrow deltas place the RTX 4070 SUPER in a tightly contested performance band among high-end mobile and workstation parts, far removed from the integrated graphics tier occupied by the Radeon 840M.

Where Each One Wins

The Radeon 840M claims advantages in power efficiency and physical footprint. Its thermal design power is 15 W, compared to 220 W for the RTX 4070 SUPER. It requires no power connectors, while the NVIDIA card uses a single 16-pin connector and recommends a 550 W power supply. The 840M is an integrated graphics processor, taking no expansion slot, whereas the RTX 4070 SUPER is a dual-slot discrete card measuring 267 mm in length, 112 mm in height, and 42 mm in width. The AMD part also carries a higher boost clock at 2900 MHz versus 2475 MHz, though this does not translate into higher throughput given its smaller shader array.

The RTX 4070 SUPER wins in every compute and rendering category that the database records. It has 7,168 shading units against 256, 224 texture mapping units against 16, and 80 render output units against 8. Its ray tracing core count stands at 56 versus 4, and it includes 224 tensor cores, a feature class entirely absent from the Radeon 840M's specification sheet. The NVIDIA card's pixel rate of 198.0 GPixel/s and texture rate of 554.4 GTexel/s dwarf the AMD part's corresponding figures. Its FP32 throughput of 35.48 TFLOPS is a direct multiple of the 840M's 1,484.8 GFLOPS.

The RTX 4070 SUPER also wins on memory capacity and bandwidth. Its 12 GB GDDR6X frame buffer with 504.2 GB/s bandwidth supports high-resolution textures and heavy geometry workloads. The 840M's system-shared memory offers no fixed bandwidth figure, making its performance dependent on the host platform's memory configuration. For gaming at high detail settings, ray tracing workloads, GPU compute, and content creation, the benchmark data and specifications indicate the RTX 4070 SUPER is the only viable option of the two.

Architecture Differences

The two GPUs come from different architectural lineages. The Radeon 840M uses AMD's RDNA 3.5 architecture, built on TSMC's 4 nm process node, and is part of the Navi III IGP generation for Strix Point Mobile. It is based on the Krackan Point chip. The RTX 4070 SUPER uses NVIDIA's Ada Lovelace architecture, built on TSMC's 5 nm process, and is part of the GeForce 40 series with the AD104 chip.

Transistor counts and die sizes are only disclosed for the NVIDIA part. The RTX 4070 SUPER contains 35,800 million transistors on a 294 mm² die, giving a transistor density of 121.8 million per square millimeter. The Radeon 840M's transistor count and die size are listed as unknown, so any comparison on those grounds cannot be made from the recorded data.

Compute resource allocation differs massively. The RTX 4070 SUPER fields 7,168 shading units, 224 TMUs, and 80 ROPs. The Radeon 840M fields 256 shading units, 16 TMUs, and 8 ROPs. The NVIDIA card includes 56 ray tracing cores and 224 tensor cores, while the AMD part lists 4 ray tracing cores and no tensor cores. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature parity exists at the software level.

Memory architecture separates the two entirely. The RTX 4070 SUPER uses dedicated GDDR6X on a 192-bit interface with 504.2 GB/s bandwidth. The Radeon 840M uses system-shared memory with a system-shared bus width, and its bandwidth is labeled system dependent. The NVIDIA card's memory clock runs at 1313 MHz with 21 Gbps effective transfer rate, while the AMD part has no fixed memory clock listed.

The bus interface also differs. The RTX 4070 SUPER uses PCIe 4.0 x16, while the Radeon 840M uses PCIe 4.0 x8. Display outputs are defined for the RTX 4070 SUPER as 1x HDMI 2.1 and 3x DisplayPort 1.4a, whereas the 840M's outputs are described as portable device dependent. The production status of the RTX 4070 SUPER is end-of-life, while the Radeon 840M remains active.
