Architecture Differences

The AMD Radeon 8040S and Intel Arc G3 represent fundamentally different architectural approaches from their respective manufacturers. The AMD part is based on RDNA 3.5, built on the Strix Halo chip, and belongs to the Navi Mobile (RX 8000M) generation. It uses a 4 nm process from TSMC with a die size of 308 mm². The Intel Arc G3, by contrast, employs Xe3-LPG architecture on the Panther Lake chip, part of the Arc Graphics-M (Panther Lake) generation, manufactured on Intel's own 3 nm process with an unknown die size.

The compute resource allocation differs notably. AMD's Radeon 8040S packs 1024 shading units, 64 texture mapping units, and 32 render output units. Intel's Arc G3 has more shading units at 1280, but fewer TMUs at 40 and fewer ROPs at 20. RT core counts also differ: AMD includes 16 ray tracing cores, while Intel provides 10.

Clock behavior shows a significant contrast. The AMD GPU has a base clock of 1295 MHz and a boost clock of 2800 MHz. Intel's part starts much lower at 300 MHz base but boosts to 2400 MHz. The power envelopes diverge sharply as well: AMD's TDP is 55 W, while Intel's is 25 W. Both are integrated graphics processors (IGP) with no power connectors and portable-device-dependent display outputs.

Memory architecture is shared in concept: both use system-shared memory with system-dependent bandwidth, and neither has dedicated VRAM. The bus interface differs, with AMD using PCIe 5.0 x16 while Intel uses an IGP bus interface. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The release dates are far apart, with AMD launching on January 5, 2025, and Intel scheduled for May 31, 2026.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Radeon 8040S and Intel Arc G3. The head-to-head benchmark array is empty, and neither GPU records any wins in direct competition. This absence of comparative data means any performance differentiation must be derived from the individual benchmark scores available for the AMD part and the architectural specifications of both.

The AMD Radeon 8040S has a full set of PassMark benchmark results. Its DirectX 10 score is 48, DirectX 11 score is 80, DirectX 12 score is 47, and DirectX 9 score is 134. The G2D score reaches 1052, while the G3D score is 10578. The GPU compute score is 5138. These results place the AMD GPU at the 17th percentile among all GPUs, with an average benchmark score of 2440.

The Intel Arc G3 has no recorded benchmark scores in any category. Its average benchmark score is 0, and it has no nearest rivals listed. Despite this lack of measured data, its 50th percentile ranking reflects a database position based on expected or projected performance rather than actual measurements.

Looking at the AMD GPU's nearest rivals provides context for its performance tier. The AMD Radeon 8040S sits 0.3% above the NVIDIA GeForce 710M (average score 2433), 0.6% above the Intel HD Graphics 610 (2425), and 0.7% above the NVIDIA GeForce GT 710M (2422). It trails the AMD Radeon RX 7400 by 1.1% (2467). These narrow margins indicate the Radeon 8040S operates in a performance bracket typical of entry-level integrated graphics.

Without Intel Arc G3 benchmark data, the comparison relies on compute specifications. The Intel part's FP32 throughput of 6.144 TFLOPS exceeds AMD's 5.734 TFLOPS by approximately 7%. In FP16, Intel shows a 2:1 ratio delivering 12.29 TFLOPS, while AMD achieves 5.734 TFLOPS at a 1:1 ratio. Pixel rate favors AMD at 89.60 GPixel/s versus 48.00 GPixel/s for Intel, a difference of roughly 87%. Texture rate similarly favors AMD at 179.2 GTexel/s against Intel's 96.00 GTexel/s.

The Verdict

The data indicates two very different products with distinct positioning. The AMD Radeon 8040S is a measured, shipping product with concrete benchmark results and a clear performance profile. Its average score of 2440 places it among older entry-level discrete GPUs and modern integrated solutions, as evidenced by its proximity to the GeForce 710M and HD Graphics 610.

The Intel Arc G3, by contrast, has no measured performance data in the database. Its 50th percentile ranking appears to be a placeholder or projection, not a result of actual testing. The architectural specifications suggest higher raw compute potential in FP32 and FP16, but the lower pixel rate and texture rate indicate potential bottlenecks in rasterization-heavy workloads.

For users relying on measured performance, the AMD Radeon 8040S is the only option with verifiable results. It delivers 10578 in PassMark G3D and 5138 in GPU compute, with a modest 55 W TDP. The Intel Arc G3's 25 W TDP suggests better energy efficiency, but without benchmark scores, that advantage cannot be quantified.

The AMD part's higher pixel rate of 89.60 GPixel/s and texture rate of 179.2 GTexel/s compared to Intel's 48.00 GPixel/s and 96.00 GTexel/s suggest AMD may handle fill-rate-bound scenarios better. Conversely, Intel's higher shading unit count and FP32 throughput point toward compute-bound advantages, though these remain theoretical until benchmark data emerges.

Specification Differences

The two GPUs differ across nearly every measurable specification. The AMD Radeon 8040S uses RDNA 3.5 architecture on a 4 nm TSMC process with a 308 mm² die, while the Intel Arc G3 uses Xe3-LPG on Intel's 3 nm process with an unknown die size. Manufacturing is split between TSMC for AMD and Intel for the Arc G3.

Clock speeds differ substantially: AMD's base is 1295 MHz and boost is 2800 MHz, versus Intel's 300 MHz base and 2400 MHz boost. Power consumption shows AMD at 55 W TDP and Intel at 25 W TDP. The bus interface also differs, with AMD using PCIe 5.0 x16 and Intel using an IGP connection.

Compute unit counts diverge: AMD has 1024 shading units, 64 TMUs, and 32 ROPs, while Intel has 1280 shading units, 40 TMUs, and 20 ROPs. Ray tracing cores number 16 for AMD and 10 for Intel. Pixel rate is 89.60 GPixel/s for AMD versus 48.00 GPixel/s for Intel, and texture rate is 179.2 GTexel/s versus 96.00 GTexel/s.

FP32 performance favors Intel at 6.144 TFLOPS against AMD's 5.734 TFLOPS. FP16 also favors Intel at 12.29 TFLOPS (2:1) versus AMD's 5.734 TFLOPS (1:1). Both use system-shared memory with system-dependent bandwidth. Release dates are January 5, 2025, for AMD and May 31, 2026, for Intel. AMD's predecessor is Polaris Mobile, while Intel has no listed predecessor. Both GPUs are active production parts with no launch MSRP recorded.
