Analysis: AMD Radeon 840M vs NVIDIA GeForce RTX 4080 SUPER

Head-to-Head Benchmarks

The AMD Radeon 840M and NVIDIA GeForce RTX 4080 SUPER do not share any direct benchmark results in the database. The RTX 4080 SUPER has a full suite of recorded scores, while the Radeon 840M has no individual benchmark entries. The absence of overlapping data means a direct per-test comparison is impossible. What the database does show is the RTX 4080 SUPER's absolute performance level and its position against its nearest rivals. Its average benchmark score is 54,209, which places it at the 86th percentile of all GPUs in the database. The Radeon 840M sits at the 50th percentile with an average score of zero, reflecting the lack of recorded tests rather than a measured performance result.

The RTX 4080 SUPER's strongest recorded result comes from Geekbench Vulkan, where it scores 260,075. Its OpenCL result is 219,065. In Passmark's suite, the G3D score is 34,245, while GPU Compute reaches 19,822. The DirectX 9 test yields 381, DirectX 11 yields 301, and DirectX 10 yields 193. The DirectX 12 result is 134, and the G2D score is 1,270. The 3DMark Steel Nomad DX12 test shows 6,600 points. These scores confirm the GPU's placement in the 86th percentile, but they cannot be weighed against the 840M because the 840M has no comparable entries.

The nearest rival data for the RTX 4080 SUPER shows a tight cluster. The RTX 4080 averages 54,247, which is 0.1% higher than the SUPER's 54,209. The AMD Radeon Pro W5700X averages 54,828, which is 1.1% higher. The AMD Radeon RX 6750 GRE 12 GB averages 55,698, which is 2.7% higher. The AMD Radeon 8060S averages 55,757, which is 2.8% higher. The SUPER trails all four of its nearest recorded rivals by narrow margins, between 0.1% and 2.8%. This indicates that the recorded data places the RTX 4080 SUPER at the lower edge of its immediate performance tier, despite its high percentile rank overall.

Architecture Differences

The two GPUs come from fundamentally different design lineages. The AMD Radeon 840M uses the RDNA 3.5 architecture on a 4 nm process at TSMC, built as part of the Navi III IGP generation under the Krackan Point chip. It is an integrated graphics processor, denoted by its IGP slot width and its lack of power connectors. The NVIDIA GeForce RTX 4080 SUPER uses the Ada Lovelace architecture on a 5 nm process at TSMC, built around the AD103 chip with 45,900 million transistors on a 379 mm² die, giving a transistor density of 121.1M per mm². The 840M's transistor count and die size are recorded as unknown.

The compute resources differ by an order of magnitude. The 840M has 256 shading units, 16 texture mapping units, 8 ROPs, and 4 ray tracing cores. The RTX 4080 SUPER has 10,240 shading units, 320 TMUs, 112 ROPs, 80 ray tracing cores, and 320 tensor cores. The 840M has no tensor core field. The 840M's FP32 throughput is 1,484.8 GFLOPS, while the RTX 4080 SUPER reaches 52.22 TFLOPS. Both maintain a 1:1 ratio between FP16 and FP32.

Clock behavior also differs. The 840M has a base clock of 400 MHz and a boost clock of 2900 MHz. The RTX 4080 SUPER has a base clock of 2295 MHz and a boost clock of 2550 MHz. The 840M runs its memory from the system pool, with the bus width, capacity, and type all listed as System Shared, and bandwidth as System Dependent. The RTX 4080 SUPER uses 16 GB of GDDR6X on a 256 bit bus with 736.3 GB/s of bandwidth. Pixel rate for the 840M is 23.20 GPixel/s, versus 285.6 GPixel/s for the RTX 4080 SUPER. Texture rate is 46.40 GTexel/s versus 816.0 GTexel/s.

Power and physical characteristics separate them sharply. The 840M has a TDP of 15 W, uses no power connectors, and is an IGP. The RTX 4080 SUPER has a TDP of 320 W, uses a single 16-pin connector, requests a 700 W suggested power supply, and occupies a triple-slot footprint. Its dimensions are 310 mm in length, 140 mm in height, and 61 mm in width. The 840M's dimensions are not recorded.

The Verdict

The recorded data draws a clear separation. The RTX 4080 SUPER delivers measured performance at the 86th percentile, with an average benchmark score of 54,209 and a full set of DirectX, OpenCL, Vulkan, and compute results. The Radeon 840M has no recorded benchmark scores and sits at the 50th percentile, which in this database reflects the absence of test data rather than a measured outcome. The RTX 4080 SUPER is the only one of the two with verified performance evidence.

The RTX 4080 SUPER's nearest rival data adds context. It is marginally behind the RTX 4080, the Radeon Pro W5700X, the Radeon RX 6750 GRE 12 GB, and the Radeon 8060S, with deltas from -0.1% to -2.8%. This places it as a high-tier card that is slightly below the top of its own cluster in the database. Its production status is End-of-life, and its successor is the GeForce 50 series.

The Radeon 840M is an active product, released later, with a 15 W TDP and an integrated design. It targets a completely different power and physical envelope. The database contains no benchmark entries for it, so any performance claim would lack recorded support. The RTX 4080 SUPER is the clear choice for workloads requiring proven, high-level GPU throughput, based on the available measurements. The 840M is suitable for systems where an IGP with a 15 W TDP and no external power connector is the design constraint, but its performance cannot be quantified from the database.

Where Each One Wins

The RTX 4080 SUPER wins in every measurable performance domain, because the 840M has no recorded benchmark scores. The SUPER's Geekbench Vulkan score of 260,075 and OpenCL score of 219,065 demonstrate strong compute and API-level performance. Its Passmark G3D score of 34,245 and GPU Compute score of 19,822 reinforce that position. The DirectX 9 score of 381, DirectX 11 score of 301, DirectX 10 score of 193, and DirectX 12 score of 134 provide a full legacy and modern API profile. The 3DMark Steel Nomad DX12 result of 6,600 adds a dedicated modern gaming workload. The SUPER also wins on raw specifications: 10,240 shading units versus 256, 736.3 GB/s of dedicated memory bandwidth versus a system-shared pool, and 52.22 TFLOPS versus 1,484.8 GFLOPS.

The Radeon 840M wins on the parameters that define an integrated part. Its TDP of 15 W is dramatically lower than the SUPER's 320 W. It requires no power connectors, whereas the SUPER uses a 1x 16-pin connector and a 700 W suggested power supply. The 840M is an IGP with a portable-device-dependent display output, while the SUPER is a triple-slot discrete card with 1x HDMI 2.1 and 3x DisplayPort 1.4a. The 840M uses PCIe 4.0 x8, the SUPER uses PCIe 4.0 x16. The 840M is Active in production status, while the SUPER is End-of-life. For a system built around minimal power draw and integration, the 840M holds the advantage. For any workload requiring measured, high-end graphics throughput, the RTX 4080 SUPER is the only one with database evidence to support it.
