AMD Radeon 8065S vs Intel Arc B580 Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Radeon 8065S contains no benchmark entries, so the direct comparison relies entirely on the Intel Arc B580’s measured results and the database’s percentile positioning. The Arc B580 holds a 68th percentile ranking among all GPUs, while the Radeon 8065S sits at the 50th percentile. This 18-point gap in percentile placement indicates that the Intel part is positioned notably higher in the overall performance distribution.

The Arc B580’s average benchmark score of 23,021 places it in a tight cluster of competitors. Its nearest rival, the AMD Radeon RX 580 2048SP, averages 23,061, which is only 0.2% higher. The NVIDIA GeForce RTX 2080 trails by 0.6% with a score of 22,895, while the RTX 3080 sits 0.7% above at 23,172. The NVIDIA P106-100 leads the group at 23,249, a 1% advantage. These deltas show the Arc B580 performing within a narrow band of roughly 1.5% across four established GPUs.

In individual workloads, the Arc B580 delivers its strongest result in Geekbench Vulkan with a score of 109,672, followed by 92,821 in Geekbench OpenCL. The PassMark G3D score of 15,748 represents the primary gaming-oriented metric, while PassMark GPU Compute adds 7,729. The DirectX 12 and DirectX 10 scores are identical at 76, with DirectX 11 higher at 128 and DirectX 9 at 183. The 2D score of 709 is substantially lower than the 3D figure, reflecting the distinct workloads involved.

The Radeon 8065S has no measured scores in the database, meaning no direct win totals can be assigned. The wins column shows zero for both parts. Because the AMD GPU lacks benchmark data, the head-to-head comparison is inherently one-sided in terms of recorded evidence. The Arc B580’s results are the only quantitative data available for performance assessment.

Architecture Differences

The two GPUs employ different architectures from different generations. The Radeon 8065S uses RDNA 3.5, part of the Navi Mobile (RX 8000M) generation, built on a 4 nm TSMC process. Its chip is designated Gorgon Halo with a die size of 308 mm². The Arc B580 uses Xe2-HPG architecture from the Battlemage (Arc 5) generation, fabricated on a 5 nm TSMC process with the BMG-G21 chip and a 272 mm² die. The Intel part packs 19,600 million transistors, which the database records as a density of 72.1 million per mm², while the AMD transistor count is listed as unknown.

Both GPUs share identical shading unit and TMU counts: 2,560 shading units and 160 texture mapping units. The ROP counts differ, with the Radeon at 64 and the Arc at 80. Ray tracing cores also diverge significantly: the Radeon has 40 RT cores, while the Arc has 20. Neither part lists tensor cores in the database.

Clock behavior separates the two clearly. The Radeon 8065S has a base clock of 1295 MHz and a boost clock of 3000 MHz, a substantial 1,705 MHz boost range. The Arc B580 runs at a flat 2670 MHz for both base and boost, indicating no dynamic boost headroom in the recorded specifications. Memory configurations are fundamentally different. The Radeon uses system-shared memory with a system-dependent bandwidth, effectively relying on the host platform’s memory subsystem. The Arc B580 carries 12 GB of dedicated GDDR6 memory on a 192-bit bus, delivering 456.0 GB/s of bandwidth at 2375 MHz (19 Gbps effective).

Pixel and texture rates reflect these architectural choices. The Radeon achieves 192.0 GPixel/s and 480.0 GTexel/s. The Arc reaches 213.6 GPixel/s and 427.2 GTexel/s. The Radeon has a higher texture rate by 52.8 GTexel/s, while the Arc leads pixel throughput by 21.6 GPixel/s. FP32 compute favors the Radeon at 15.36 TFLOPS versus 13.67 TFLOPS for the Arc. FP16 performance diverges sharply: the Radeon holds at 15.36 TFLOPS with a 1:1 ratio, while the Arc doubles to 27.34 TFLOPS with a 2:1 ratio.

Power and physical characteristics differ substantially. The Radeon 8065S consumes 55 W and is an integrated GPU (IGP) with no power connectors, fitting a portable device. The Arc B580 draws 190 W, uses a dual-slot design, requires one 8-pin connector, and recommends a 450 W power supply. The Radeon uses PCIe 5.0 x16, while the Arc uses PCIe 4.0 x8. Display outputs also diverge: the Radeon is portable-device dependent, while the Arc provides 1x HDMI 2.1a and 3x DisplayPort 2.1.

Both APIs are identical: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Radeon measures 308 mm² against the Arc’s 272 mm², yet the Arc is a physical card at 272 mm in length, 115 mm in height, and 45 mm in width. The Radeon has no listed physical dimensions because it is an integrated solution. Release dates differ by roughly a year: the Radeon launched at the end of 2025, while the Arc arrived in December 2024.

Where Each One Wins

The Intel Arc B580 wins on the basis of recorded benchmark evidence. Its percentile ranking of 68 versus 50 for the Radeon indicates a stronger overall position in the database distribution. The Arc’s average score of 23,021 is the only average score available, so any performance comparison defaults to the Intel part’s favor. In memory, the Arc’s dedicated 12 GB GDDR6 with 456.0 GB/s bandwidth provides predictable performance that does not depend on host system memory characteristics. The Radeon’s system-shared memory bandwidth is listed as system dependent, meaning its memory performance varies with the platform.

The Radeon 8065S wins on raw compute specifications. Its FP32 throughput of 15.36 TFLOPS exceeds the Arc’s 13.67 TFLOPS by 1.69 TFLOPS, a 12.4% advantage. Its texture rate of 480.0 GTexel/s beats the Arc’s 427.2 GTexel/s by 52.8 GTexel/s. The Radeon also features twice as many ray tracing cores, 40 versus 20, which suggests greater ray tracing throughput capacity per clock. The Radeon’s boost clock of 3000 MHz is 330 MHz higher than the Arc’s fixed 2670 MHz.

Power efficiency favors the Radeon decisively. At 55 W versus 190 W, the Radeon draws roughly 29% of the Arc’s power budget. This makes the Radeon suitable for portable devices without discrete power connectors, while the Arc requires a dedicated 8-pin connector and a 450 W power supply recommendation. The Radeon’s PCIe 5.0 x16 interface doubles the bandwidth ceiling of the Arc’s PCIe 4.0 x8 link, which matters for system-shared memory access patterns.

The Arc B580 wins on pixel throughput and physical form factor flexibility. Its 213.6 GPixel/s exceeds the Radeon’s 192.0 GPixel/s. The Arc’s 80 ROPs provide 16 more than the Radeon’s 64. The Arc also offers standard display outputs with 1x HDMI 2.1a and 3x DisplayPort 2.1, whereas the Radeon’s outputs depend entirely on the portable device implementation.

The Verdict

The database presents a lopsided comparison due to missing benchmark data for the Radeon 8065S. For users who require measured performance evidence, the Intel Arc B580 is the only part with recorded scores. Its 68th percentile ranking, average score of 23,021, and near-parity with the RTX 2080 (0.6% ahead) and RX 580 2048SP (0.2% behind) establish a concrete performance level. The Arc’s 12 GB GDDR6 memory and 456.0 GB/s bandwidth make it suitable for standalone graphics workloads where memory isolation matters.

The Radeon 8065S appeals on specification grounds. Its higher FP32 throughput, higher texture rate, double the RT cores, and dramatically lower 55 W power draw make it a strong candidate for integrated, power-constrained portable systems. The absence of benchmark scores means its real-world performance cannot be confirmed from the database, so any selection based on the Radeon relies on architectural specifications rather than measured outcomes.

The choice separates by use case and evidence availability. The Arc B580 is the data-backed option for discrete desktop graphics with a 190 W power budget, a dual-slot cooler, and a 450 W power supply. The Radeon 8065S serves integrated mobile scenarios where 55 W power, no connectors, and system-shared memory are the operating constraints. The Arc’s 68th percentile versus the Radeon’s 50th percentile suggests the Intel part occupies a higher tier in the overall distribution, but this ranking stems only from the Arc’s measured data.

Neither part’s successor is listed, and both remain active in production. The Arc B580 has a launch MSRP of 249 USD, which is recorded once here. The Radeon has no launch MSRP in the database.
