AMD Radeon 8065S vs NVIDIA GeForce RTX 5080 Mobile Comparison

Where Each One Wins

The recorded data presents a stark contrast between these two mobile graphics solutions. The AMD Radeon 8065S, built on the Gorgon Halo chip with RDNA 3.5 architecture, currently holds no benchmark entries in the database, resulting in an average benchmark score of zero and a percentile ranking of 50 among all GPUs. In contrast, the NVIDIA GeForce RTX 5080 Mobile, using the GB203 chip with Blackwell 2.0 architecture, has ten recorded benchmark scores, an average score of 38349, and sits at the 81st percentile.

The RTX 5080 Mobile wins every measurable category where data exists. Its strengths appear across DirectX 12, Vulkan, OpenCL, and legacy DirectX workloads. The highest single benchmark score for the RTX 5080 Mobile comes from Geekbench Vulkan at 169754, followed closely by Geekbench OpenCL at 166986. The PassMark G3D score of 27711 indicates strong general 3D rendering performance, while the PassMark GPU Compute score of 12134 shows capable compute throughput. The RTX 5080 Mobile also delivers solid legacy performance with PassMark DirectX 9 at 314, DirectX 11 at 253, and DirectX 10 at 171, plus a DirectX 12 score of 116.

The 8065S, lacking any submitted benchmarks, cannot claim wins in any workload category. The database shows zero wins for the AMD part and zero wins for the NVIDIA part in head-to-head comparisons, meaning no direct comparative testing has been recorded. The 8065S relies on its architectural specifications, such as a 3000 MHz boost clock and 15.36 TFLOPS FP32 throughput, to define its theoretical capability, but no measured data confirms real-world performance.

FAQ

Architecture Differences

The architectural divide between these two mobile GPUs is substantial. The AMD Radeon 8065S uses the Gorgon Halo chip fabricated on a 4 nm TSMC process with a die size of 308 mm². The transistor count remains unknown. The RTX 5080 Mobile uses the GB203 chip on a 5 nm TSMC process with a larger 378 mm² die and 45,600 million transistors, yielding a transistor density of 120.6M per mm².

The compute configuration differs sharply. The RTX 5080 Mobile contains 7680 shading units, 240 texture mapping units, 96 render output units, 60 ray tracing cores, and 240 tensor cores. The 8065S has 2560 shading units, 160 TMUs, 64 ROPs, and 40 ray tracing cores, with no tensor core count listed. This gives the RTX 5080 Mobile three times the shading units and 3.5 times the tensor cores for AI workloads.

Clock behavior shows the AMD part runs much higher frequencies. The 8065S has a base clock of 1295 MHz and a boost clock of 3000 MHz, while the RTX 5080 Mobile operates at 975 MHz base and 1500 MHz boost. The higher boost clock helps the 8065S reach 192.0 GPixel/s pixel rate and 480.0 GTexel/s texture rate, compared to 144.0 GPixel/s and 360.0 GTexel/s for the RTX 5080 Mobile. Despite lower clocks, the RTX 5080 Mobile achieves higher absolute throughput due to its larger execution units.

Memory architecture represents a fundamental divergence. The 8065S uses system shared memory with system dependent bandwidth, tying performance to the host platform's memory subsystem. The RTX 5080 Mobile uses dedicated 16 GB GDDR7 on a 256-bit bus delivering 896.0 GB/s, providing predictable and high bandwidth independent of system configuration.

Both GPUs share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both use PCIe 5.0 x16 interfaces and are integrated processors with portable device dependent display outputs. The 8065S belongs to the Navi Mobile (RX 8000M) generation with RDNA 3.5, succeeding Polaris Mobile. The RTX 5080 Mobile belongs to the GeForce 50 Mobile generation with Blackwell 2.0, succeeding GeForce 40 Mobile. The RTX 5080 Mobile released in April 2025, while the 8065S carries a release date of December 2025.

The Verdict

The data supports a clear choice for most workloads: the NVIDIA GeForce RTX 5080 Mobile. With ten recorded benchmark scores averaging 38349 and an 81st percentile ranking, it demonstrates measurable performance across DirectX 9 through 12, Vulkan, OpenCL, and compute tasks. Its nearest rivals, including the RTX 4080 Mobile and MX570 variants, all sit within 1% of its average score, indicating the RTX 5080 Mobile competes at the high end of mobile graphics.

The AMD Radeon 8065S presents a different situation. Without any benchmark data, its 50th percentile ranking and zero average score offer no evidence of real-world capability. The specifications suggest a low-power integrated solution: 55 W TDP, system shared memory, and 15.36 TFLOPS FP32. The architecture includes 40 ray tracing cores and a 3000 MHz boost clock, but no measured results confirm these translate into competitive performance.

For users requiring dedicated memory bandwidth, the RTX 5080 Mobile's 896.0 GB/s GDDR7 clearly outperforms the system dependent memory of the 8065S. For compute-heavy tasks, the RTX 5080 Mobile's 23.04 TFLOPS FP32 and 240 tensor cores provide substantial headroom. The 8065S, conversely, offers lower power consumption at 55 W versus 80 W, which may suit thin-and-light designs where battery life matters more than raw performance.

The verdict follows the evidence: choose the RTX 5080 Mobile for any workload requiring measured, repeatable performance. The 8065S remains an unverified option with theoretical specifications but no data to support its adoption for specific tasks.

Head-to-Head Benchmarks

Direct comparisons between the two GPUs are impossible because the database contains no head-to-head benchmark entries. The 8065S has zero recorded scores, while the RTX 5080 Mobile has ten. The wins tally shows zero for each side, reflecting the absence of comparable tests rather than a competitive outcome.

The RTX 5080 Mobile's strongest results appear in Geekbench Vulkan at 169754 and Geekbench OpenCL at 166986. These scores indicate strong cross-platform API performance. The PassMark G3D score of 27711 and GPU Compute score of 12134 demonstrate balanced 3D rendering and compute capabilities. The 3DMark Steel Nomad DX12 score of 4952 provides a modern DirectX 12 gaming metric.

Legacy API support shows the RTX 5080 Mobile handles older workloads efficiently: PassMark DirectX 9 at 314, DirectX 11 at 253, DirectX 10 at 171, and DirectX 12 at 116. The PassMark G2D score of 1095 covers 2D operations. These varied scores paint a picture of a versatile GPU capable across API generations.

The 8065S offers no comparable numbers. Its specification sheet lists 15.36 TFLOPS FP32 and 15.36 TFLOPS FP16, but these are theoretical maxima. The pixel rate of 192.0 GPixel/s and texture rate of 480.0 GTexel/s suggest fill-rate advantages over the RTX 5080 Mobile's 144.0 GPixel/s and 360.0 GTexel/s, but without benchmarks, these advantages remain unconfirmed. The 8065S's 40 ray tracing cores could provide competitive ray tracing, yet no scores verify this.

Given the complete absence of 8065S data, the head-to-head analysis must defer to the RTX 5080 Mobile. Its benchmark suite provides the only measurable evidence of performance in the database, and those measurements place it among the top-tier mobile GPUs.
