AMD Radeon 8065S vs Intel Arc G3 Comparison

Where Each One Wins

The AMD Radeon 8065S and Intel Arc G3 occupy different performance tiers despite both being integrated graphics solutions. The Radeon 8065S is positioned as the higher-throughput part, with its raw compute and pixel processing capabilities substantially exceeding those of the Arc G3. The database shows the 8065S delivering 15.36 TFLOPS of FP32 compute, while the Arc G3 sits at 6.144 TFLOPS, a 2.5x advantage for the AMD part.

The Radeon 8065S also holds decisive leads in texture and pixel throughput. Its 480.0 GTexel/s texture rate compares to 96.00 GTexel/s for the Arc G3, a 5x margin. Similarly, pixel fill rate stands at 192.0 GPixel/s versus 48.00 GPixel/s, again a 4x difference. For workloads that stress rasterization, texture filtering, or raw shader math, the AMD part wins across the board.

The Intel Arc G3 counters with efficiency-oriented strengths. Its 25 W TDP is less than half of the Radeon 8065S's 55 W envelope. The Arc G3 also uses a 3 nm process from Intel, while the Radeon 8065S uses a 4 nm process from TSMC. For thermally constrained portable devices, the Arc G3's lower power draw and denser process node give it a clear positioning advantage in scenarios where sustained performance per watt matters more than absolute throughput.

The Arc G3 further differentiates itself in FP16 compute. It delivers 12.29 TFLOPS at FP16 with a 2:1 ratio relative to FP32, meaning it can double its throughput on half-precision workloads. The Radeon 8065S offers 15.36 TFLOPS at FP16 but at a 1:1 ratio, meaning no such acceleration. For applications that leverage FP16 math, such as certain AI inference or compute shaders, the Intel part narrows the gap considerably, trailing by only 3.07 TFLOPS instead of the 9.216 TFLOPS gap seen in FP32.

Architecture Differences

The two GPUs come from fundamentally different architectural lineages. The AMD Radeon 8065S uses the Gorgon Halo chip built on RDNA 3.5, part of the Navi Mobile (RX 8000M) generation. The Intel Arc G3 uses the Panther Lake chip built on Xe3-LPG, part of the Arc Graphics-M (Panther Lake) generation.

The Radeon 8065S employs a 4 nm process from TSMC with a die size of 308 mm². The Arc G3 uses a 3 nm process from Intel, with the die size listed as unknown in the database. This process difference matters for power efficiency and density, though the Arc G3's smaller transistor budget is evident from its lower core counts.

Shader resources diverge sharply. The Radeon 8065S packs 2560 shading units, 160 texture mapping units, and 64 ROPs. The Arc G3 has 1280 shading units, 40 TMUs, and 20 ROPs. That is exactly half the shaders, a quarter of the TMUs, and under a third of the ROPs. Ray tracing hardware follows a similar pattern: the 8065S includes 40 RT cores, while the Arc G3 includes 10.

Both GPUs use system-shared memory, meaning they draw from the host's system RAM rather than dedicated VRAM. Memory bus width and type are likewise system-dependent for both parts. This makes memory bandwidth a function of the host platform rather than a fixed specification.

Clock behavior differs as well. The Radeon 8065S runs at a 1295 MHz base clock and boosts to 3000 MHz. The Arc G3 runs at a 300 MHz base clock and boosts to 2400 MHz. The Arc G3's low base clock suggests aggressive power gating, ramping up only when needed, while the Radeon part maintains a higher idle baseline.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs are listed as portable device dependent for both, reflecting their integrated nature. The Radeon 8065S interfaces via PCIe 5.0 x16, while the Arc G3 uses an IGP bus interface.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark scores for these two parts, and neither GPU has individual benchmark results in the database. Both sit at the 50th percentile among all GPUs with an average benchmark score of 0. This means the performance comparison below relies entirely on the architectural specifications recorded in the database.

The largest single-specification win for the AMD Radeon 8065S is in texture rate. At 480.0 GTexel/s, it outpaces the Arc G3's 96.00 GTexel/s by a factor of exactly 5. This stems from the combination of 160 TMUs versus 40 and a higher boost clock of 3000 MHz versus 2400 MHz. Texture-heavy workloads, including most modern game rendering, will see a decisive advantage on the AMD part.

Pixel fill rate shows a 4x advantage for the Radeon 8065S: 192.0 GPixel/s versus 48.00 GPixel/s. With 64 ROPs versus 20, the AMD part can resolve and write framebuffer data at a much higher rate, which benefits high-resolution rendering and multisampled anti-aliasing scenarios.

FP32 compute follows at 15.36 TFLOPS versus 6.144 TFLOPS, a 2.5x difference. This gap reflects the 2560 shading units versus 1280, compounded by the clock advantage. General-purpose compute workloads, vertex processing, and pixel shader execution all favor the Radeon part.

The FP16 comparison narrows the gap but still favors AMD: 15.36 TFLOPS versus 12.29 TFLOPS, a 1.25x advantage. The Arc G3's 2:1 FP16 ratio effectively doubles its throughput on half-precision operations, while the Radeon 8065S maintains a 1:1 ratio. In FP16-specific workloads, the Intel part is far more competitive than the raw shader count would suggest.

Boost clocks show a 600 MHz advantage for the Radeon 8065S (3000 MHz versus 2400 MHz), while base clocks show a 995 MHz advantage for the AMD part (1295 MHz versus 300 MHz). The Arc G3's low base clock is unusual and indicates a design focused on idle power savings rather than sustained low-frequency operation.
