AMD Radeon 840M vs NVIDIA GeForce RTX 5080 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results between the AMD Radeon 840M and the NVIDIA GeForce RTX 5080. The head-to-head comparison fields are empty, and the win counts for both sides are zero. This means the two products have never been tested against each other in a controlled benchmark environment within this database. The absence of direct comparison data is notable given the extreme performance gulf implied by their individual specifications and placement in the overall GPU hierarchy.

What can be established from the available data is the relative standing of each product against all other GPUs in the database. The RTX 5080 sits at the 87th percentile of all GPUs, while the Radeon 840M sits at exactly the 50th percentile. This percentile gap indicates that the RTX 5080 outperforms a substantial majority of all recorded GPUs, whereas the Radeon 840M lands in the middle of the distribution. The RTX 5080 has a recorded average benchmark score of 56,083 across ten individual tests, while the Radeon 840M has an average benchmark score of zero, reflecting the absence of any recorded benchmark runs for the integrated part.

For the RTX 5080, the individual benchmark results provide a detailed performance profile. In 3DMark Steel Nomad DX12, it scores 8,637. In Geekbench OpenCL, it reaches 235,901, and in Geekbench Vulkan it achieves 255,450. The PassMark suite shows a G3D score of 36,565, a GPU compute score of 21,789, a G2D score of 1,415, and legacy DirectX tests ranging from 151 in DirectX 12 to 389 in DirectX 9. The DirectX 10 and DirectX 11 scores are 208 and 324 respectively. These numbers confirm a desktop discrete GPU operating at a very high performance tier.

The nearest rivals to the RTX 5080 in the database provide context for its positioning. The AMD Radeon 8060S averages 55,757, which places it 0.6% behind the RTX 5080. The AMD Radeon RX 6750 GRE 12 GB averages 55,698, a 0.7% deficit. The AMD Radeon Pro W5700X averages 54,828, sitting 2.3% behind. The AMD Radeon RX 9070 GRE averages 57,367, which is 2.2% ahead of the RTX 5080. These delta percentages are small, indicating that the RTX 5080 competes in a tightly packed performance band at the top of the desktop GPU market. The data shows a spread of only 4.5 percentage points between the slowest and fastest of these four rivals.

The Radeon 840M has no nearest rivals listed and no benchmark scores, so no comparative percentage analysis can be performed for it. Its 50th percentile standing is the only positional data available. The integrated nature of the part, with system-shared memory and a 15 W TDP, contrasts sharply with the discrete RTX 5080, which carries 16 GB of dedicated GDDR7 memory and a 360 W TDP. These specification gaps strongly suggest that any direct benchmark comparison would show a massive performance differential, but the database currently contains no numbers to quantify that gap.

The Verdict

The data indicates two products designed for entirely different segments of the GPU market. The AMD Radeon 840M is an integrated graphics processor with system-shared memory, a 400 MHz base clock, a 2,900 MHz boost clock, and a 15 W TDP. It has no recorded benchmark scores and no nearest rivals, placing it at the 50th percentile of all GPUs. The NVIDIA GeForce RTX 5080 is a discrete dual-slot desktop card with a 360 W TDP, a 2,295 MHz base clock, a 2,617 MHz boost clock, 16 GB of GDDR7 memory, and a 960.0 GB/s memory bandwidth. It has ten recorded benchmark scores and an average of 56,083, placing it at the 87th percentile.

From the recorded data alone, the RTX 5080 is the clear performance leader. Its average benchmark score of 56,083 versus the 840M's zero recorded scores means no comparison can be made on equal terms. The RTX 5080's nearest rival data shows it trading blows with other high-end desktop cards within a 2.3% margin, confirming its position near the top of the desktop GPU hierarchy. The Radeon 840M, by contrast, has no comparable data points and must be assessed solely on its specification sheet, which indicates an entry-level integrated solution.

The RTX 5080's benchmark scores reveal consistency across different test suites. Its Geekbench Vulkan score of 255,450 is higher than its OpenCL score of 235,901, suggesting strong low-level API performance. The PassMark G3D score of 36,565 is roughly 1.7 times its GPU compute score of 21,789, indicating that rasterization workloads perform relatively better than compute workloads in that suite. The legacy DirectX results show expected scaling, with DirectX 9 at 389, DirectX 10 at 208, DirectX 11 at 324, and DirectX 12 at 151, although these numbers are difficult to interpret without comparable data from the 840M.

The 50th percentile ranking for the 840M should not be misread as a mid-range discrete GPU. The integrated part's system-shared memory and 15 W TDP place it in a fundamentally different power and thermal envelope. The RTX 5080's 360 W TDP is 24 times higher, and its dedicated GDDR7 memory with 960.0 GB/s bandwidth bears no resemblance to the 840M's system-dependent memory bandwidth. For any workload that stresses GPU compute or graphics throughput, the RTX 5080 is the only choice supported by recorded data.

Specification Differences

The two GPUs differ in nearly every measurable specification category. The RTX 5080 uses the GB203 chip with Blackwell 2.0 architecture on a 5 nm TSMC process. The Radeon 840M uses the Krackan Point chip with RDNA 3.5 architecture on a 4 nm TSMC process. The RTX 5080 has 45,600 million transistors on a 378 mm² die with a transistor density of 120.6M per mm². The 840M has unknown transistor count and die size.

Clock speeds differ substantially. The RTX 5080 runs at a 2,295 MHz base clock and a 2,617 MHz boost clock, with memory at 1,875 MHz (30 Gbps effective). The 840M runs at a 400 MHz base clock and a 2,900 MHz boost clock, with system-shared memory. Despite the 840M's higher boost clock, the RTX 5080's massive shader count advantage dominates throughput calculations.

The shader configuration shows the scale of difference. The RTX 5080 has 10,752 shading units, 336 TMUs, 112 ROPs, 84 RT cores, and 336 tensor cores. The 840M has 256 shading units, 16 TMUs, 8 ROPs, and 4 RT cores, with no tensor cores listed. Pixel rate for the RTX 5080 is 293.1 GPixel/s versus 23.20 GPixel/s for the 840M. Texture rate is 879.3 GTexel/s versus 46.40 GTexel/s. FP32 compute is 56.28 TFLOPS versus 1,484.8 GFLOPS, a roughly 38-fold difference.

Power and physical specifications also diverge sharply. The RTX 5080 is a dual-slot card measuring 304 mm in length, 137 mm in height, and 40 mm in width, with a 1x 16-pin power connector and a suggested PSU of 750 W. The 840M is an IGP with no slot width, no power connectors, and no suggested PSU. The RTX 5080 uses PCIe 5.0 x16, while the 840M uses PCIe 4.0 x8. Display outputs differ as well: the RTX 5080 has 1x HDMI 2.1b and 3x DisplayPort 2.1b, while the 840M's outputs are portable device dependent.

Architecture Differences

The architectural divide between these two GPUs is fundamental. The RTX 5080 belongs to the GeForce 50-series generation, using Blackwell 2.0 architecture. The Radeon 840M belongs to the Navi III IGP generation for Strix Point Mobile, using RDNA 3.5 architecture. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical, but the underlying hardware implementations differ completely.

The RTX 5080's Blackwell 2.0 architecture includes 336 tensor cores, which are absent from the 840M's specification listing. Tensor cores enable AI-accelerated workloads, and their presence in the RTX 5080 but not the 840M indicates a capability gap in machine learning and neural network applications. The RTX 5080 also has 84 RT cores versus 4 in the 840M, a 21-fold difference in ray tracing hardware. The RTX 5080's FP16 throughput matches its FP32 at 56.28 TFLOPS, while the 840M's FP16 also matches its FP32 at 1,484.8 GFLOPS with a 1:1 ratio, so neither part uses a packed FP16 path.

The process nodes differ by one nanometer: the RTX 5080 uses 5 nm TSMC, while the 840M uses 4 nm TSMC. The 840M's smaller process node does not compensate for its far smaller shader count. The RTX 5080's 45,600 million transistors on 378 mm² give it a density of 120.6M per mm², while the 840M's transistor data is unknown. The RTX 5080's predecessor is the GeForce 40 series and its successor is the GeForce 60 series. The 840M's predecessor is the Navi II IGP, and it has no listed successor.

Memory architecture differs at the most basic level. The RTX 5080 has dedicated 16 GB GDDR7 on a 256-bit bus with 960.0 GB/s bandwidth. The 840M uses system-shared memory, meaning its bandwidth and capacity depend entirely on the host system's RAM configuration. This makes the 840M's memory performance variable and system-dependent, while the RTX 5080's memory performance is fixed and specified. The RTX 5080 also has a 1,875 MHz memory clock at 30 Gbps effective, a figure that has no equivalent for the 840M.

Where Each One Wins

The recorded data supports a clear use-case split based on specification differences and benchmark availability. The RTX 5080 wins in every scenario where recorded benchmark scores exist. Its ten benchmark results span 3DMark, Geekbench, and PassMark suites, covering modern DirectX 12 workloads, compute tasks, and legacy DirectX APIs. Its average score of 56,083 and 87th percentile ranking confirm its suitability for high-end desktop gaming, GPU compute, and any workload requiring substantial dedicated memory bandwidth.

The RTX 5080's 336 tensor cores and 84 RT cores give it dedicated hardware for AI and ray tracing workloads, features that the 840M lacks entirely in the case of tensor cores and has only 4 units of in the case of RT cores. The 960.0 GB/s memory bandwidth supports high-resolution textures and large datasets, while the 16 GB GDDR7 capacity handles modern game assets and compute workloads without spilling to system memory. The 360 W TDP and dual-slot cooling design indicate a product intended for sustained high-load operation in a desktop chassis.

The Radeon 840M wins only in the categories of power efficiency and physical integration. Its 15 W TDP is a fraction of the RTX 5080's 360 W, making it suitable for portable devices where battery life and thermal limits are primary constraints. Its IGP form factor with no power connectors and no slot width means it requires no additional cooling or power delivery hardware. The 4 nm process node is smaller than the RTX 5080's 5 nm node, though the 840M's unknown transistor count prevents a density comparison. The 840M's higher boost clock of 2,900 MHz versus the RTX 5080's 2,617 MHz is a clock speed advantage, but the 840M's 256 shading units cannot translate that clock advantage into competitive throughput.

The 840M's 50th percentile ranking, while based on no recorded benchmark scores, suggests it sits in the middle of the overall GPU distribution when considering all GPUs including other integrated parts and low-end discrete cards. For users constrained to a 15 W power envelope, the 840M is the only viable option between the two, as the RTX 5080's power and physical requirements preclude its use in such systems. For any scenario where performance is the priority and power consumption is not a limiting factor, the RTX 5080's recorded benchmark data makes it the clear choice.
