AMD Radeon 8065S vs Intel Arc 140V Mobile Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Radeon 8065S and the Intel Arc 140V Mobile shows a clear performance hierarchy, though direct benchmark scores are not available in the database. Instead, the specification-derived throughput rates provide the basis for comparison. The AMD part delivers a pixel rate of 192.0 GPixel/s against 62.40 GPixel/s for Intel, which means the Radeon 8065S processes pixels at roughly three times the speed. Texture rate follows a similar pattern: 480.0 GTexel/s versus 124.8 GTexel/s, a margin of 3.85 times in favor of AMD.

Compute throughput amplifies the gap. The Radeon 8065S reaches 15.36 TFLOPS in FP32, while the Arc 140V Mobile manages 3.994 TFLOPS. That is a 3.85x advantage, identical to the texture rate ratio, which makes sense given both are derived from the same shader and TMU counts. In FP16, the situation changes notably. The AMD GPU sustains 15.36 TFLOPS with a 1:1 ratio, meaning no throughput penalty for half-precision work. The Intel part posts 7.987 TFLOPS with a 2:1 ratio, so it doubles its FP32 rate by pairing two FP16 ops per shader clock. Even with that efficiency, AMD still leads by 1.92x in raw FP16 throughput.

Clock speeds tell a different story. The Intel Arc 140V Mobile runs at a base of 300 MHz and boosts to 1950 MHz. The Radeon 8065S starts at 1295 MHz base and boosts to 3000 MHz. While AMD has the higher boost, the Intel part’s lower base clock is unusual for an integrated GPU, likely reflecting a power-optimized design. The boost delta of 1050 MHz in AMD’s favor contributes to its throughput lead, but the architectural differences below explain why the raw clock gap does not fully account for the performance spread.

Both GPUs share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Neither has benchmark entries in the database, so the percentileVsAllGpus field sits at 50 for both, indicating no recorded sample set. The winsA and winsB counters are both zero, confirming that no direct head-to-head benchmark data exists. The analysis therefore relies on the measurable specification differences, which consistently favor the AMD part across every throughput metric.

Architecture Differences

The Radeon 8065S uses the Gorgon Halo chip built on RDNA 3.5, fabricated on TSMC’s 4 nm node. The Intel Arc 140V Mobile uses the Lunar Lake chip with Xe2-LPG architecture, also on TSMC silicon but at 3 nm. The smaller process node gives Intel a density advantage in theory, but the die sizes show AMD’s larger investment: 308 mm² versus 172 mm². That 136 mm² difference reflects a substantially bigger GPU block in the AMD design.

Shader resources diverge sharply. The Radeon 8065S packs 2560 shading units, 160 TMUs, and 64 ROPs. The Arc 140V Mobile has 1024 shading units, 64 TMUs, and 32 ROPs. AMD’s counts are exactly 2.5x for shaders, 2.5x for TMUs, and 2x for ROPs. Ray tracing hardware follows a similar pattern: 40 RT cores on AMD versus 8 on Intel, a 5x difference. Neither GPU lists tensor cores, so AI acceleration relies on the respective shader arrays and any vendor-specific extensions not captured in the database.

Memory architecture is identical in form: both use system-shared memory with a system-dependent bus width and bandwidth. Neither has dedicated VRAM, so performance scales with the host platform’s memory subsystem. The bus interface differs: the Radeon 8065S uses PCIe 5.0 x16, while the Arc 140V Mobile is listed as IGP, meaning it connects through the processor’s integrated fabric rather than a discrete PCIe link. This could affect bandwidth allocation in some workloads, though the database does not quantify the impact.

Power envelopes differ significantly. The Radeon 8065S has a TDP of 55 W, while the Arc 140V Mobile draws 37 W. That 18 W gap explains part of the performance difference, but the architectural efficiency also varies. The Radeon’s FP32-to-TDP ratio is 0.279 TFLOPS/W, while the Intel part achieves 0.108 TFLOPS/W. AMD delivers 2.59x more compute per watt based on these figures. The slot width for both is IGP, and the Radeon 8065S uses no external power connectors. The Intel part’s power connector field is null, but as an IGP, it also draws power through the motherboard.

Release timing separates the two by over a year. The Arc 140V Mobile launched on 2024-09-23, while the Radeon 8065S arrived on 2025-12-31. Both are listed as Active production status. Their predecessors differ: AMD’s is Polaris Mobile, Intel’s is HD Graphics-M. The generation names reflect distinct product families: Navi Mobile (RX 8000M) for AMD, Arc Graphics-M (Lunar Lake) for Intel.

Where Each One Wins

The Radeon 8065S wins in every measured throughput category. Pixel fill rate at 192.0 GPixel/s suits high-resolution rendering and heavy post-processing effects, where ROP throughput becomes the bottleneck. The 64 ROPs give it a clear edge in framebuffer-bound scenarios. Texture-heavy workloads, such as detailed surface shading or procedural terrain, benefit from the 480.0 GTexel/s rate. Compute workloads that rely on FP32 math, including physics simulations and general-purpose GPU tasks, see 15.36 TFLOPS available. The 1:1 FP16 ratio means machine learning inference or half-precision rendering does not incur a throughput penalty, making the AMD part more flexible for mixed-precision pipelines.

The Arc 140V Mobile wins on power efficiency in absolute terms. Its 37 W TDP is 18 W lower than the Radeon’s 55 W, which matters in thin-and-light laptops where thermal limits are strict. The 2:1 FP16 ratio, while lower in absolute throughput, still provides a 2x boost over its own FP32 rate, which can accelerate certain AI or media workloads that tolerate reduced precision. The smaller die at 172 mm² and 3 nm process also suggest lower manufacturing cost per die, though pricing data is not recorded. The higher base clock on AMD (1295 MHz versus 300 MHz) implies the Intel part spends more time at low clocks under idle or light load, potentially saving power in everyday use.

For gaming, the Radeon 8065S’s higher pixel and texture rates directly translate to better frame rates at the same settings, assuming system memory bandwidth is not the limiting factor. The 40 RT cores versus 8 suggest a significant advantage in ray-traced scenes, though without benchmark data, the magnitude is speculative. The Arc 140V Mobile’s lower TDP makes it suitable for passively cooled designs or devices where the GPU shares a thermal budget with the CPU. The PCIe 5.0 x16 interface on the AMD part allows for potential external bandwidth scaling, while the Intel IGP interface is fixed to the integrated path.
