AMD Radeon 840M vs NVIDIA GeForce RTX 4050 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between the AMD Radeon 840M and the NVIDIA GeForce RTX 4050 Mobile. The RTX 4050 Mobile holds benchmark scores across every recorded test, while the Radeon 840M has no benchmark entries in the database. This absence of recorded data for the 840M means the comparison relies entirely on the NVIDIA GPU's measured results.

The RTX 4050 Mobile's average benchmark score of 19,049 places it in the 63rd percentile among all GPUs in the database. Its nearest rivals include the AMD Radeon RX 6600 with an average score of 19,036, a delta of 0.1%, and the NVIDIA Quadro K6000 at 19,030, also a 0.1% delta. The NVIDIA Tesla K20m scores 19,089, putting the RTX 4050 Mobile 0.2% behind that part. The NVIDIA RTX 2000 Ada Generation scores 18,954, placing the RTX 4050 Mobile 0.5% ahead.

Looking at individual workloads, the RTX 4050 Mobile delivers 74,748 in Geekbench OpenCL and 75,235 in Geekbench Vulkan. These scores indicate strong compute throughput in both API environments. The PassMark suite shows a DirectX 11 score of 130, DirectX 12 at 61, DirectX 10 at 79, and DirectX 9 at 184. The GPU compute score of 5,947 reflects substantial compute capability, while the G3D score of 14,423 and G2D score of 633 round out the picture.

The Radeon 840M, by contrast, has no benchmark scores recorded in the database and an average benchmark score of zero. Its percentile ranking of 50 suggests it sits at the median of all GPUs, but this figure is not supported by any measured test results. The data indicates the RTX 4050 Mobile outperforms the Radeon 840M in every measurable category, though the lack of 840M scores makes a direct head-to-head comparison impossible from the recorded numbers alone.

Architecture Differences

The two GPUs come from fundamentally different architectural families. The AMD Radeon 840M uses the RDNA 3.5 architecture on a 4 nm process node, fabricated by TSMC. It is part of the Navi III IGP generation and is built on the Krackan Point chip. The NVIDIA GeForce RTX 4050 Mobile uses the Ada Lovelace architecture on a 5 nm process node, also from TSMC, and is built on the AD107 chip within the GeForce 40 Mobile generation.

The RTX 4050 Mobile carries 18,900 million transistors on a 159 mm² die, giving it a transistor density of 118.9M per mm². The Radeon 840M's transistor count and die size are recorded as unknown. Both GPUs use PCIe 4.0 x8 as their bus interface and have portable device dependent display outputs.

Shader and compute resources differ sharply. The Radeon 840M has 256 shading units, 16 texture mapping units, 8 raster output units, and 4 ray tracing cores. The RTX 4050 Mobile has 2,560 shading units, 80 TMUs, 48 ROPs, 20 ray tracing cores, and 80 tensor cores. The RTX 4050 Mobile's tensor cores are a notable feature absent from the Radeon 840M's specification list.

Clock behavior also diverges. The Radeon 840M has a base clock of 400 MHz and a boost clock of 2,900 MHz. The RTX 4050 Mobile has a base clock of 1,455 MHz and a boost clock of 1,755 MHz. Memory clock for the RTX 4050 Mobile is 2,000 MHz with 16 Gbps effective speed, while the Radeon 840M's memory clock is listed as system shared.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both are classified as active production status. The Radeon 840M is an integrated GPU with system shared memory, while the RTX 4050 Mobile is also classified as IGP slot width but uses dedicated GDDR6 memory.

The Verdict

The recorded data indicates a clear division of roles. The NVIDIA GeForce RTX 4050 Mobile delivers measured performance across all benchmark categories, with an average score of 19,049 and a 63rd percentile ranking. Its nearest rivals sit within a narrow band of 0.5% or less, confirming consistent positioning in the database. The GPU's 2,560 shading units, 80 tensor cores, 20 ray tracing cores, and 8.986 TFLOPS FP32 throughput provide substantial headroom for compute and graphics workloads.

The AMD Radeon 840M presents a different profile. With no recorded benchmark scores, its performance cannot be quantified from the database. Its 256 shading units, 4 ray tracing cores, and 1,484.8 GFLOPS FP32 output indicate a more modest compute envelope. The 15 W TDP versus the RTX 4050 Mobile's 50 W TDP suggests the Radeon 840M targets low-power integrated scenarios, while the RTX 4050 Mobile is positioned for higher-performance mobile systems.

The RTX 4050 Mobile's dedicated 6 GB GDDR6 memory with a 96-bit bus and 192.0 GB/s bandwidth represents a significant advantage over the Radeon 840M's system shared memory, whose bandwidth is system dependent. For workloads requiring sustained memory throughput, the RTX 4050 Mobile's architecture is better suited. The Radeon 840M's 4 nm process node offers a denser manufacturing approach, but the RTX 4050 Mobile's larger resource pool and dedicated memory make it the stronger choice for demanding applications.

The data supports selecting the RTX 4050 Mobile for tasks requiring measured performance, ray tracing, tensor core acceleration, and dedicated video memory. The Radeon 840M, meanwhile, fits scenarios prioritizing low power consumption at 15 W and integrated simplicity, though its exact performance level remains unquantified in the database.

Specification Differences

The two GPUs differ across nearly every recorded specification. The Radeon 840M uses a 4 nm process node, while the RTX 4050 Mobile uses 5 nm. Both are fabricated by TSMC. The RTX 4050 Mobile has a known transistor count of 18,900 million, a die size of 159 mm², and a transistor density of 118.9M per mm², while the Radeon 840M's figures are unknown.

Memory configurations are fundamentally different. The Radeon 840M uses system shared memory with system shared size, type, and bus width, and system dependent bandwidth. The RTX 4050 Mobile has 6 GB of GDDR6 memory on a 96-bit bus with 192.0 GB/s bandwidth.

Compute resource counts differ substantially: the Radeon 840M has 256 shading units, 16 TMUs, 8 ROPs, and 4 ray tracing cores, while the RTX 4050 Mobile has 2,560 shading units, 80 TMUs, 48 ROPs, and 20 ray tracing cores. The RTX 4050 Mobile also has 80 tensor cores, a feature the Radeon 840M lacks.

Clock speeds diverge in opposite directions. The Radeon 840M has a lower base clock of 400 MHz but a higher boost clock of 2,900 MHz. The RTX 4050 Mobile has a higher base clock of 1,455 MHz but a lower boost clock of 1,755 MHz. The RTX 4050 Mobile's memory clock is 2,000 MHz with 16 Gbps effective speed, while the Radeon 840M's memory clock is system shared.

Pixel and texture rates reflect the resource gap. The Radeon 840M produces 23.20 GPixel/s and 46.40 GTexel/s, while the RTX 4050 Mobile produces 84.24 GPixel/s and 140.4 GTexel/s. FP32 compute is 1,484.8 GFLOPS for the Radeon 840M versus 8.986 TFLOPS for the RTX 4050 Mobile, both with 1:1 FP16 ratios.

TDP differs by 35 W: the Radeon 840M draws 15 W, the RTX 4050 Mobile draws 50 W. Both have IGP slot width, no power connectors, and PCIe 4.0 x8 interfaces. Release dates are 2025-02-28 for the Radeon 840M and 2023-01-02 for the RTX 4050 Mobile. The RTX 4050 Mobile's predecessor is GeForce 30 Mobile and successor is GeForce 50 Mobile, while the Radeon 840M's predecessor is Navi II IGP.
