AMD Radeon 8065S vs NVIDIA GeForce RTX 4070 AD103 Comparison

Where Each One Wins

The recorded data presents a fundamental split between two very different mobile graphics solutions. The AMD Radeon 8065S operates as an integrated graphics processor (IGP) with a 55 W TDP, designed to share system memory and rely entirely on the host device for output and power delivery. The NVIDIA GeForce RTX 4070 AD103 is a discrete, dual-slot add-in board with a 200 W TDP, its own 12 GB GDDR6X frame buffer, and a dedicated 16-pin power connector.

Based on the specification data, the NVIDIA part wins decisively in raw compute throughput. Its FP32 performance of 29.15 TFLOPS is nearly double the AMD part's 15.36 TFLOPS. The RTX 4070 AD103 also fields 5888 shading units against 2560, 184 texture mapping units against 160, and 184 tensor cores where the AMD part lists none. The NVIDIA GPU further holds the advantage in memory bandwidth with 504.2 GB/s from a 192-bit GDDR6X interface, while the AMD 8065S's bandwidth is listed as system dependent. The RTX 4070 AD103 also has more ray tracing cores (46 versus 40).

The AMD Radeon 8065S wins in the efficiency and integration domain. Its 55 W TDP represents a fraction of the NVIDIA part's 200 W draw. The AMD GPU requires no power connectors at all, consumes no additional slot space beyond the portable device itself, and uses whatever system memory is available rather than a fixed 12 GB allocation. Its boost clock of 3000 MHz exceeds the NVIDIA part's 2475 MHz boost, and its base clock of 1295 MHz is lower than the NVIDIA's 1920 MHz base. The AMD part also achieves a higher pixel rate of 192.0 GPixel/s against 158.4 GPixel/s for the NVIDIA GPU, despite the latter's larger shader count. The texture rate is nearly even, with the AMD part at 480.0 GTexel/s and the NVIDIA part at 455.4 GTexel/s.

The AMD Radeon 8065S uses a newer PCIe 5.0 x16 bus interface, while the NVIDIA GeForce RTX 4070 AD103 uses PCIe 4.0 x16. In terms of production status, the AMD part is listed as active, while the NVIDIA part is end-of-life.

Architecture Differences

The AMD Radeon 8065S is built on the Gorgon Halo chip using RDNA 3.5 architecture, fabricated on a 4 nm process at TSMC with a die size of 308 mm². It belongs to the Navi Mobile (RX 8000M) generation. The NVIDIA GeForce RTX 4070 AD103 uses the AD103 chip with Ada Lovelace architecture, fabricated on a 5 nm process at TSMC. Its die size is larger at 379 mm², and it packs 45,900 million transistors with a transistor density of 121.1M per mm². The AMD part's transistor count is unknown.

Memory architecture differs fundamentally. The AMD Radeon 8065S has no dedicated VRAM; its memory size, type, and bus width are all listed as system shared, with bandwidth dependent on the host system. The NVIDIA GeForce RTX 4070 AD103 carries 12 GB of GDDR6X on a 192-bit bus, delivering 504.2 GB/s of bandwidth. The NVIDIA memory clock is listed at 1313 MHz with 21 Gbps effective speed.

The NVIDIA GPU includes 184 tensor cores, a feature absent from the AMD Radeon 8065S listing. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part's display outputs are specified as 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the AMD part's outputs are described as portable device dependent.

The AMD part has no power connectors and is an IGP, meaning it integrates into the host processor package. The NVIDIA part is a dual-slot card with a 16-pin connector and a suggested power supply of 550 W. Physical dimensions for the NVIDIA card are 240 mm in length, 110 mm in height, and 40 mm in width. The AMD part has no listed dimensions, consistent with its integrated nature.

Release timing differs: the AMD Radeon 8065S launched on 2025-12-31 (listed as active), while the NVIDIA GeForce RTX 4070 AD103 launched on 2024-02-29 and is now end-of-life, with the GeForce 50 series listed as its successor. The AMD part's predecessor is Polaris Mobile.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results or rival comparison scores for either GPU. Both parts have zero recorded benchmark entries, an average benchmark score of zero, and an identical percentile rank of 50 against all GPUs. The nearest rivals lists are empty for both items.

The specification data, however, provides measurable deltas that indicate clear performance separation. In FP32 compute, the NVIDIA GeForce RTX 4070 AD103 delivers 29.15 TFLOPS, which is 89.8% higher than the AMD Radeon 8065S's 15.36 TFLOPS. The shading unit count tells a similar story: 5888 versus 2560, a 130% advantage for NVIDIA. Texture rate favors AMD slightly at 480.0 GTexel/s versus 455.4 GTexel/s, a 5.4% edge. Pixel rate favors AMD more clearly, with 192.0 GPixel/s versus 158.4 GPixel/s, an advantage of 21.2%.

Memory bandwidth is a decisive NVIDIA win: 504.2 GB/s versus system dependent for the AMD part. If a portable device pairs the 8065S with dual-channel LPDDR5X memory, real-world bandwidth might approach several hundred GB/s, but the database lists no such figure. The NVIDIA part's 12 GB dedicated frame buffer also removes any contention with the CPU for memory resources.

Clock speeds tell a nuanced story. The AMD Radeon 8065S has a 3000 MHz boost clock, 21.2% higher than the NVIDIA's 2475 MHz boost. But the NVIDIA part's base clock of 1920 MHz is 48.3% higher than AMD's 1295 MHz base. The higher AMD boost clock helps explain its pixel rate advantage despite fewer ROPs (64 for both) and its texture rate edge despite fewer TMUs.

Ray tracing hardware shows near parity in count (40 for AMD, 46 for NVIDIA), but NVIDIA's Ada Lovelace architecture typically includes dedicated RT acceleration features not reflected in raw core counts. The database does not provide RT benchmark scores to quantify this.

The Verdict

The data indicates that the NVIDIA GeForce RTX 4070 AD103 is the performance leader for applications that demand maximum compute throughput. Its FP32 output of 29.15 TFLOPS, 5888 shading units, and 504.2 GB/s of dedicated memory bandwidth position it clearly ahead in rendering, compute, and AI workloads that can utilize its 184 tensor cores. The 12 GB GDDR6X frame buffer removes memory capacity concerns for modern game assets and creative workloads. This GPU is a dual-slot discrete card requiring a 550 W power supply, so it belongs in a laptop or desktop replacement chassis that can accommodate its 200 W TDP and physical footprint of 240 mm by 110 mm by 40 mm.

The AMD Radeon 8065S serves a different purpose entirely. As an IGP with a 55 W TDP, no power connectors, and system shared memory, it fits into slim portable devices where discrete graphics is not an option. Its 3000 MHz boost clock and higher pixel rate (192.0 GPixel/s versus 158.4 GPixel/s) suggest it can handle lighter rendering tasks efficiently. The texture rate of 480.0 GTexel/s actually exceeds the NVIDIA part's 455.4 GTexel/s, indicating competitive fill-rate performance in certain scenarios. Its PCIe 5.0 x16 interface provides headroom for system memory bandwidth, though the actual performance depends entirely on the host device's memory configuration.

For a user who needs maximum frame rates and compute performance in a system that can house a discrete card, the NVIDIA GeForce RTX 4070 AD103 is the clear choice from the data. For a user who prioritizes portability, low power draw, and integration, the AMD Radeon 8065S is the only option that fits those constraints. The AMD part's active production status versus NVIDIA's end-of-life status also matters for long-term availability. Neither part shows benchmark scores in the database, so the verdict rests on the specification deltas.
