AMD Radeon 8065S vs Intel Arc Graphics 64EU Comparison

The AMD Radeon 8065S and Intel Arc Graphics 64EU represent two fundamentally different approaches to integrated graphics. The Radeon 8065S, built on the RDNA 3.5 architecture, is a high-end mobile part with a 50th percentile ranking among all GPUs. The Intel Arc Graphics 64EU, based on Xe-LPG, sits at the 3rd percentile. The data shows a massive performance gap, yet each part has a distinct role depending on the platform and workload priorities.

The Verdict

The AMD Radeon 8065S is the clear performance leader based on every recorded specification. Its FP32 throughput of 15.36 TFLOPS dwarfs the Intel Arc Graphics 64EU's 1.946 TFLOPS, a difference of roughly 7.9x. The Radeon 8065S should be the choice for anyone needing serious compute capability from an integrated GPU, such as content creation, GPU-accelerated rendering, or high-end gaming at portable-device resolutions.

The Intel Arc Graphics 64EU serves a different purpose. It is a modest integrated solution for mainstream Arrow Lake-S desktop processors. Its benchmark score of 733 in 3DMark Steel Nomad DX12 places it in the lowest percentile tier, but it is on par with its direct sibling, the Intel Arc Graphics 32EU, which also scores 733. The data shows it is 1.4% faster than the AMD Radeon HD 6470M (score 723) and 2.4% slower than the NVIDIA GeForce GT 415M (score 751). This positions the Arc 64EU as a basic display and light-media solution, not a gaming or compute powerhouse.

Architecture Differences

The two GPUs come from different architectural generations and process nodes. The AMD Radeon 8065S uses the RDNA 3.5 architecture on a 4 nm process from TSMC, with a die size of 308 mm². The Intel Arc Graphics 64EU uses the Xe-LPG architecture on a 3 nm process, also from TSMC, with a die size of 243 mm² and a transistor count of 17,800 million. Intel's part has a transistor density of 73.3M per mm², a figure not listed for the AMD chip.

The compute configuration diverges sharply. The Radeon 8065S has 2560 shading units, 160 texture mapping units (TMUs), 64 raster operation units (ROPs), and 40 ray tracing cores. The Intel Arc Graphics 64EU has 512 shading units, 32 TMUs, and 16 ROPs, with no dedicated ray tracing cores listed. Clock behavior also differs: the Radeon 8065S runs at a 1295 MHz base and 3000 MHz boost, while the Intel part starts at a 300 MHz base and reaches a 1900 MHz boost.

The Intel Arc Graphics 64EU uses a Ring Bus interface, while the AMD Radeon 8065S connects via PCIe 5.0 x16. Both are integrated graphics processors (IGP) that share system memory, with bandwidth described as "System Dependent" for each. The AMD part's predecessor is Polaris Mobile, whereas the Intel part's predecessor is HD Graphics.

Head-to-Head Benchmarks

The recorded data includes no direct head-to-head benchmark results between these two specific parts, but the specification comparison provides clear performance indicators. The most striking difference is in raw compute throughput: the Radeon 8065S delivers 15.36 TFLOPS of FP32 performance, exactly 7.9 times the Intel Arc Graphics 64EU's 1.946 TFLOPS. This makes the AMD part decisively faster for any FP32 workload, including general 3D rendering and physics calculations.

Texture and pixel throughput follow the same pattern. The Radeon 8065S achieves 480.0 GTexel/s, which is 7.9 times the Intel part's 60.80 GTexel/s. Pixel fill rates show the Radeon 8065S at 192.0 GPixel/s versus 30.40 GPixel/s for the Intel Arc Graphics 64EU, a 6.3x advantage. The AMD part also has 40 ray tracing cores, whereas the Intel part lists no ray tracing hardware, so any ray-traced workload will necessarily run on the AMD side without a direct comparison.

In the one recorded benchmark, the Intel Arc Graphics 64EU scores 733 in 3DMark Steel Nomad DX12. Its nearest rivals include the Intel Arc Graphics 32EU and 24EU, both also scoring 733, indicating no performance delta between Intel's own low-end Arc variants. The AMD Radeon HD 6470M trails by 1.4%, and the NVIDIA GeForce GT 415M leads by 2.4%. This places the Intel part in a narrow band of legacy and entry-level GPUs, far below the Radeon 8065S's 50th percentile standing among all GPUs.

Specification Differences

The two parts differ across nearly every measurable specification. The process node is 4 nm for AMD and 3 nm for Intel. The AMD die measures 308 mm², while the Intel die is 243 mm². Intel lists 17,800 million transistors, while AMD's transistor count is unknown. The AMD Radeon 8065S has a base clock of 1295 MHz and a boost clock of 3000 MHz; the Intel Arc Graphics 64EU has a 300 MHz base and 1900 MHz boost.

Shading units number 2560 on the AMD side versus 512 on the Intel side. TMUs are 160 versus 32, and ROPs are 64 versus 16. The AMD part has 40 ray tracing cores; the Intel part has none listed. FP32 performance is 15.36 TFLOPS versus 1.946 TFLOPS. FP16 performance is 15.36 TFLOPS with a 1:1 ratio for AMD, while Intel delivers 3.891 TFLOPS with a 2:1 ratio, meaning Intel's FP16 throughput is double its FP32 rate. Pixel rates are 192.0 GPixel/s versus 30.40 GPixel/s, and texture rates are 480.0 GTexel/s versus 60.80 GTexel/s.

Power ratings differ: the Radeon 8065S has a TDP of 55 W, while the Intel Arc Graphics 64EU has a TDP of 65 W. The AMD part uses PCIe 5.0 x16; the Intel part uses a Ring Bus. Display outputs are portable-device dependent for AMD and motherboard dependent for Intel. The AMD part lists no power connectors, while the Intel part has no connector information. Release dates also differ, with the Intel part released in October 2024 and the AMD part dated late December 2025.

Where Each One Wins

The AMD Radeon 8065S wins decisively in every compute and rendering metric recorded. Its 2560 shading units, 160 TMUs, and 64 ROPs provide 7.9x the FP32 throughput, 7.9x the texture rate, and 6.3x the pixel rate of the Intel Arc Graphics 64EU. The presence of 40 ray tracing cores means it can handle ray-traced effects where the Intel part has no hardware support. The 3000 MHz boost clock and 55 W TDP indicate a performance-oriented design for portable devices that still maintains a relatively low power draw. Its 50th percentile ranking among all GPUs confirms it as a mid-tier performer capable of substantial GPU work.

The Intel Arc Graphics 64EU wins in efficiency of integration. Its 3 nm process node and 243 mm² die size with 17,800 million transistors offer a dense, compact solution for desktop motherboards. The 65 W TDP is modest, and the Ring Bus interface suits a mainstream processor package. Its benchmark score of 733 ties it with the Arc 32EU and 24EU, showing consistent performance across Intel's low-end Arc lineup. The FP16 ratio of 2:1 means it can double its FP32 rate to 3.891 TFLOPS when workloads support it, which may aid certain media or AI tasks.

For users, the choice depends on the platform. The Radeon 8065S is the pick for portable devices where GPU performance matters, such as gaming or creative work on the go. The Intel Arc Graphics 64EU suits desktop systems that need basic graphics output, video playback, and light acceleration without a discrete GPU. The data confirms that the AMD part is in a different performance class entirely, while the Intel part sits at the entry level alongside legacy GPUs like the HD 6470M and GT 415M.
