AMD Radeon 8065S vs Intel Arc A580 Comparison

The Verdict

The database comparison between the AMD Radeon 8065S and the Intel Arc A580 shows two fundamentally different products aimed at different use cases. The Radeon 8065S is an integrated graphics processor (IGP) designed for portable devices, consuming 55 W with a PCIe 5.0 x16 interface and system-shared memory. The Arc A580 is a dual-slot discrete graphics card with a 175 W power draw, 8 GB of dedicated GDDR6 memory on a 256-bit bus, and a 450 W suggested power supply.

Benchmark data is only available for the Intel Arc A580, which has a percentile rank of 87 among all GPUs and an average benchmark score of 57,756. The Radeon 8065S has no recorded benchmark scores and sits at the 50th percentile. The Arc A580 delivers 12.29 TFLOPS of FP32 compute and 24.58 TFLOPS of FP16 compute, while the Radeon 8065S offers 15.36 TFLOPS in both FP32 and FP16 at a 1:1 ratio.

For users building a desktop system with a dedicated power supply and space for a dual-slot card, the Arc A580 is the only option with verified performance data. For users needing graphics in a thin, portable device without add-in card support, the Radeon 8065S is the appropriate choice based on its 55 W TDP, IGP slot width, and lack of power connectors. The data does not support a direct performance comparison, as the Radeon 8065S has no benchmark entries, but the architectural differences are clear: one is a system-on-chip integrated solution, the other is a standalone discrete GPU.

Architecture Differences

The Radeon 8065S uses the Gorgon Halo chip built on RDNA 3.5 architecture, fabricated on TSMC's 4 nm process. It belongs to the Navi Mobile (RX 8000M) generation. The die size is 308 mm², and the transistor count is listed as unknown. The GPU features 2560 shading units, 160 texture mapping units, 64 render output units, and 40 ray tracing cores. Base clock is 1295 MHz with a boost clock of 3000 MHz.

The Arc A580 uses the DG2-512 chip built on Intel's Xe-HPG architecture, fabricated on TSMC's 6 nm process. It belongs to the Alchemist (Arc 5) generation. The die size is 406 mm² with 21,700 million transistors, giving a transistor density of 53.4M per mm². The GPU features 3072 shading units, 192 texture mapping units, 96 render output units, and 24 ray tracing cores. Base clock is 1700 MHz with a boost clock of 2000 MHz.

Memory configurations differ substantially. The Radeon 8065S uses system-shared memory with system-dependent bandwidth, meaning performance scales with the host system's RAM. The Arc A580 has 8 GB of GDDR6 memory on a 256-bit bus, delivering 512.0 GB/s of dedicated bandwidth. This gives the Arc A580 predictable memory performance independent of the host system.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Radeon 8065S uses a PCIe 5.0 x16 bus interface, while the Arc A580 uses PCIe 4.0 x16. The Radeon 8065S has no power connectors and a 55 W TDP, while the Arc A580 requires two 8-pin power connectors and a 175 W TDP with a 450 W suggested power supply.

Pixel rates are identical at 192.0 GPixel/s for both GPUs. Texture rates differ: the Radeon 8065S reaches 480.0 GTexel/s, while the Arc A580 achieves 384.0 GTexel/s. The Radeon 8065S has a higher FP32 throughput at 15.36 TFLOPS versus 12.29 TFLOPS for the Arc A580. However, the Arc A580 has a significant FP16 advantage at 24.58 TFLOPS with a 2:1 ratio, while the Radeon 8065S offers FP16 at only 15.36 TFLOPS with a 1:1 ratio.

Where Each One Wins

The Radeon 8065S wins in power efficiency and integration. Its 55 W TDP is less than one-third of the Arc A580's 175 W TDP. The Radeon 8065S requires no power connectors and fits as an IGP, making it suitable for portable devices where power draw and physical space are constrained. Its 3000 MHz boost clock is 50% higher than the Arc A580's 2000 MHz boost clock, and its texture rate of 480.0 GTexel/s is 25% higher than the Arc A580's 384.0 GTexel/s. The Radeon 8065S also uses the newer PCIe 5.0 x16 interface and a more advanced 4 nm process node compared to the Arc A580's 6 nm node.

The Arc A580 wins in dedicated memory and verified performance. Its 8 GB of GDDR6 memory with 512.0 GB/s bandwidth provides consistent performance without depending on system RAM. The 256-bit memory bus is wider than the system-shared configuration of the Radeon 8065S. The Arc A580 has more shading units (3072 versus 2560), more texture mapping units (192 versus 160), and more render output units (96 versus 64). Its FP16 throughput of 24.58 TFLOPS exceeds the Radeon 8065S's 15.36 TFLOPS by a substantial margin.

The Arc A580 also has verified benchmark scores. In 3DMark Steel Nomad DX12, it scores 2229. In Geekbench OpenCL, it scores 91,657. In Geekbench Vulkan, it scores 79,381. Its average benchmark score of 57,756 places it at the 87th percentile among all GPUs. The Radeon 8065S has no recorded benchmark scores and sits at the 50th percentile.

The Radeon 8065S lacks any benchmark data, preventing quantitative comparison. Its 50th percentile rank among all GPUs is based on the absence of recorded scores rather than measured performance. The Arc A580's 87th percentile rank reflects its verified performance across multiple benchmarks.

The pixel rates being identical at 192.0 GPixel/s suggests similar rasterization throughput for both GPUs, though the Radeon 8065S achieves this with fewer render output units (64 versus 96). The Radeon 8065S's higher texture rate of 480.0 GTexel/s versus 384.0 GTexel/s indicates greater texture fill capability despite having fewer texture mapping units (160 versus 192). These specifications suggest the Radeon 8065S relies on its higher clock speeds to compensate for fewer execution units.

The Arc A580's transistor count of 21,700 million on a 406 mm² die gives a density of 53.4M per mm². The Radeon 8065S's transistor count is unknown, but its 308 mm² die on a 4 nm process suggests a denser manufacturing process. The Radeon 8065S's higher boost clock of 3000 MHz compared to 2000 MHz indicates a more aggressive clock strategy, likely enabled by the smaller process node.

Both GPUs support identical API levels, including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.
