Where Each One Wins

The AMD Radeon 8065S wins decisively in raw compute throughput. Its FP32 rating of 15.36 TFLOPS versus 1.856 TFLOPS for the Intel part indicates a massive advantage in any workload that scales with shader count and clock speed. The texture rate of 480.0 GTexel/s versus 58.00 GTexel/s, and pixel rate of 192.0 GPixel/s versus 29.00 GPixel/s, show the AMD part has a significant edge in both texture-heavy and fill-rate-bound scenarios. The AMD part also supports DirectX 12 Ultimate with feature level 12_2, while the Intel part is limited to DirectX 12 with feature level 12_1, which means the AMD GPU can handle more advanced rendering features.

The Intel Iris Xe Graphics 80EU Mobile wins in power efficiency and thermal envelope. Its 15 W TDP is less than a third of the AMD part's 55 W TDP, making it suitable for thinner, lighter portable devices where sustained power draw is a constraint. The Intel part also has a higher FP16 to FP32 ratio at 3.712 TFLOPS (2:1) versus the AMD part's 15.36 TFLOPS (1:1), which could indicate a different approach to mixed-precision workloads, though the AMD part still has far higher absolute FP16 throughput.

Architecture Differences

The AMD Radeon 8065S is built on RDNA 3.5, a modern GPU architecture from AMD, fabricated on a 4 nm process at TSMC. The chip, codenamed Gorgon Halo, belongs to the Navi Mobile (RX 8000M) generation. The die size is 308 mm², which is substantial for an integrated part. The AMD architecture includes 40 ray tracing cores, enabling hardware-accelerated ray tracing, a feature entirely absent from the Intel part. The AMD GPU also has a higher bus interface of PCIe 5.0 x16, allowing for faster data transfer with the host system.

The Intel Iris Xe Graphics 80EU Mobile uses Intel's Generation 12.2 architecture, built on a 10 nm process at Intel's own fabs. The chip is based on Raptor Lake, part of the HD Graphics-M generation. The Intel part uses a Ring Bus interface rather than PCIe, which reflects its integration into the CPU die. The Intel part has no dedicated ray tracing cores, so any ray tracing workloads would need to be handled through compute shaders or other software approaches.

Both GPUs use system shared memory with system-dependent bandwidth. Neither has dedicated VRAM. The AMD part has 160 texture mapping units and 64 ROPs, while the Intel part has 40 TMUs and 20 ROPs. The AMD part supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Intel part supports DirectX 12 (12_1) and Vulkan 1.4. Both support OpenGL 4.6.

Specification Differences

The AMD Radeon 8065S has a base clock of 1295 MHz and a boost clock of 3000 MHz. The Intel Iris Xe Graphics 80EU Mobile has a base clock of 300 MHz and a boost clock of 1450 MHz. The AMD part has 2560 shading units, 160 TMUs, 64 ROPs, and 40 ray tracing cores. The Intel part has 640 shading units, 40 TMUs, and 20 ROPs, with no ray tracing cores.

The AMD part has a pixel rate of 192.0 GPixel/s and a texture rate of 480.0 GTexel/s. The Intel part has a pixel rate of 29.00 GPixel/s and a texture rate of 58.00 GTexel/s. FP32 performance is 15.36 TFLOPS for AMD and 1.856 TFLOPS for Intel. FP16 performance is 15.36 TFLOPS (1:1) for AMD and 3.712 TFLOPS (2:1) for Intel.

The AMD part has a TDP of 55 W and uses PCIe 5.0 x16. The Intel part has a TDP of 15 W and uses a Ring Bus interface. Both are integrated graphics processors with no power connectors and portable device dependent display outputs. The AMD part has a die size of 308 mm², while the Intel part has no die size listed. The AMD part was released on December 31, 2025, while the Intel part was released on January 3, 2023.

Head-to-Head Benchmarks

The recorded data shows a dominant performance gap in favor of the AMD Radeon 8065S across nearly every measurable metric. The most striking difference is in FP32 compute: the AMD part delivers 15.36 TFLOPS, which is 8.3 times the Intel part's 1.856 TFLOPS. This means for any shader-bound workload, the AMD part has a massive throughput advantage that translates directly to higher frame rates in modern games and faster execution in compute-heavy applications.

In texture processing, the AMD Radeon 8065S achieves a texture rate of 480.0 GTexel/s, which is 8.3 times the Intel part's 58.00 GTexel/s. With 160 TMUs versus 40 TMUs, the AMD part has four times the texture units, and each unit operates at a higher clock speed. This advantage is critical for games that rely heavily on texture sampling, such as open-world titles with high-resolution textures.

The pixel rate tells a similar story: the AMD part achieves 192.0 GPixel/s versus 29.00 GPixel/s for the Intel part, a 6.6 times advantage. With 64 ROPs versus 20 ROPs, the AMD part has more than three times the ROP count, and the higher boost clock of 3000 MHz versus 1450 MHz further amplifies the fill-rate lead. This matters for resolution scaling and anti-aliasing techniques that stress the ROP pipeline.

Clock speed differences are substantial. The AMD part has a base clock of 1295 MHz and a boost clock of 3000 MHz. The Intel part has a base clock of 300 MHz and a boost clock of 1450 MHz. The AMD part's boost clock is more than double the Intel part's, and its base clock is more than four times higher. This means even in sustained workloads where boost clocks cannot be maintained, the AMD part operates at a much higher frequency.

The shading unit count difference is also significant: 2560 versus 640, a 4:1 ratio. Combined with the clock advantage, the AMD part's total shader throughput is far beyond what the unit count alone suggests. The FP16 performance gap is 15.36 TFLOPS versus 3.712 TFLOPS, a 4.1 times difference, though the Intel part's 2:1 FP16 to FP32 ratio indicates it processes half-precision data more efficiently per clock than the AMD part's 1:1 ratio.

The ray tracing capability is a binary difference: the AMD part has 40 RT cores, while the Intel part has none. Any DirectX Raytracing workload will run on the AMD part with hardware acceleration, while the Intel part would need to rely on compute-based fallbacks, which are typically far slower.

Power consumption is the one area where the Intel part leads. The Intel Iris Xe Graphics 80EU Mobile has a TDP of 15 W, compared to the AMD Radeon 8065S at 55 W. This means the Intel part consumes 27% of the power of the AMD part while delivering 12% of the FP32 performance. For devices where battery life and thermal management are the primary constraints, the Intel part offers a more favorable efficiency profile, though the absolute performance difference remains enormous.

The release dates place these parts in different product generations: the Intel part launched in January 2023, while the AMD part launched in December 2025. The AMD part uses a newer 4 nm process versus the Intel part's 10 nm process, which explains part of the clock speed and efficiency gap. The AMD part's 308 mm² die size is large for an integrated GPU, reflecting its high shader count and ray tracing hardware.
