AMD Radeon 860M vs Intel Arc G3 Extreme Comparison

Head-to-Head Benchmarks

The recorded data provides a direct comparison only for AMD Radeon 860M, which has two benchmark scores in the database. The Intel Arc G3 Extreme currently has no recorded benchmark scores, so a direct head-to-head numerical comparison is not possible from the available measurements. The database lists the AMD Radeon 860M’s Geekbench OpenCL score at 22759 and its Geekbench Vulkan score at 30043. Its average benchmark score is 26401.

The AMD Radeon 860M sits at the 72nd percentile of all GPUs in the database. Its nearest rivals, based on average score, are the NVIDIA GeForce MX550 at 26421 (a delta of -0.1%), the NVIDIA GeForce RTX 5060 at 26331 (a delta of 0.3%), the AMD Radeon RX 5700 XT 50th Anniversary at 26553 (a delta of -0.6%), and the NVIDIA RTX A4000 at 26683 (a delta of -1.1%). These deltas are all within a narrow band around 1%, meaning the Radeon 860M performs essentially on par with these discrete and professional GPUs in aggregate benchmark terms.

The Intel Arc G3 Extreme has an average benchmark score of 0 and no nearest rivals listed. Its percentile rank is 50, which is the median of the database distribution, but this is based on no recorded performance data. The absence of scores means the database cannot confirm any performance relationship between the two parts. The data indicates that the Radeon 860M has measurable performance, while the Arc G3 Extreme’s performance remains unquantified.

Architecture Differences

The AMD Radeon 860M uses the Krackan Point chip, built on the RDNA 3.5 architecture, and belongs to the Navi III IGP generation for Strix Point Mobile. It is fabricated on a 4 nm process at TSMC. The Intel Arc G3 Extreme uses the Panther Lake chip, built on the Xe3-LPG architecture, and belongs to the Arc Graphics-M generation for Panther Lake. Intel fabricates this chip on a 3 nm process at its own foundry.

The Radeon 860M has 512 shading units, 32 texture mapping units, 16 render output units, and 8 ray tracing cores. The Arc G3 Extreme has 1536 shading units, 48 texture mapping units, 24 render output units, and 12 ray tracing cores. The Intel part therefore triples the shading unit count, offers 1.5 times the TMUs, 1.5 times the ROPs, and 1.5 times the ray tracing cores compared to the AMD part.

Clock behavior differs significantly. The Radeon 860M has a base clock of 600 MHz and a boost clock of 3000 MHz. The Arc G3 Extreme has a base clock of 300 MHz and a boost clock of 2500 MHz. Despite the lower boost clock, the Intel part’s much larger execution resource pool yields higher theoretical throughput. The Radeon 860M delivers 3.072 TFLOPS of FP32 performance and 3.072 TFLOPS of FP16 performance at a 1:1 ratio. The Arc G3 Extreme delivers 7.680 TFLOPS of FP32 performance and 15.36 TFLOPS of FP16 performance at a 2:1 ratio. The Intel part offers 2.5 times the FP32 throughput and 5 times the FP16 throughput.

Pixel and texture rates follow the same pattern. The Radeon 860M reaches 48.00 GPixel/s and 96.00 GTexel/s. The Arc G3 Extreme reaches 60.00 GPixel/s and 120.0 GTexel/s. The Intel part has a 25% advantage in both rates.

Power characteristics diverge sharply. The Radeon 860M has a TDP of 15 W, while the Arc G3 Extreme has a TDP of 80 W. Both are listed as IGP (integrated graphics processor) slot width with no power connectors, and both use portable device dependent display outputs. The Radeon 860M uses a PCIe 4.0 x8 bus interface, while the Arc G3 Extreme’s bus interface is listed simply as IGP.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both use system shared memory, with system dependent bandwidth. Neither part has a listed dedicated memory size, type, or bus width; memory is system shared in both cases.

The Radeon 860M was released on 2025-02-28, and its predecessor is Navi II IGP. The Arc G3 Extreme was released on 2026-05-31, and no predecessor is listed. Both are marked as Active in production status. Neither part has a listed launch MSRP.

Where Each One Wins

The AMD Radeon 860M wins in power efficiency and clock speed. Its 15 W TDP is dramatically lower than the Intel part’s 80 W TDP. Its 3000 MHz boost clock is 500 MHz higher than the Intel part’s 2500 MHz boost clock. For thermally constrained portable devices, the Radeon 860M’s low power envelope makes it the practical choice, assuming the host platform can deliver sufficient memory bandwidth, since bandwidth is system dependent for both.

The Intel Arc G3 Extreme wins in raw compute resources and theoretical throughput. Its 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores all exceed the AMD part’s counts. Its FP32 throughput of 7.680 TFLOPS is 2.5 times the Radeon 860M’s 3.072 TFLOPS. Its FP16 throughput of 15.36 TFLOPS at a 2:1 ratio is 5 times the Radeon’s 3.072 TFLOPS at a 1:1 ratio. Its pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s exceed the Radeon’s 48.00 GPixel/s and 96.00 GTexel/s.

The Radeon 860M has measurable real-world benchmark data. Its average score of 26401 places it at the 72nd percentile of all GPUs, and its nearest rivals are all within roughly 1% of its average score. The Arc G3 Extreme has no benchmark data, so its actual performance cannot be verified against the Radeon’s recorded results.

The Radeon 860M also has an earlier release date, 2025-02-28, compared to the Intel part’s 2026-05-31. The Radeon has an established predecessor in Navi II IGP, while the Intel part has no predecessor listed.

The Verdict

The data supports a clear split based on power and performance priorities. The AMD Radeon 860M is the only one of the two with recorded benchmark scores. Its Geekbench OpenCL score of 22759, Geekbench Vulkan score of 30043, and average score of 26401 place it at the 72nd percentile of all GPUs, with nearest rivals including the NVIDIA GeForce MX550, NVIDIA GeForce RTX 5060, AMD Radeon RX 5700 XT 50th Anniversary, and NVIDIA RTX A4000, all within a 1.1% delta band. For a 15 W integrated GPU, this level of measured performance is substantial.

The Intel Arc G3 Extreme offers far higher theoretical specifications. Its 1536 shading units, 7.680 TFLOPS FP32, 15.36 TFLOPS FP16, and 120.0 GTexel/s texture rate put it in a different compute class on paper. Its 80 W TDP, however, means it requires a much larger power budget, which limits its applicability in the same class of low-power portable devices as the Radeon 860M.

The database cannot validate the Intel part’s real-world performance because no benchmark scores exist for it. A user choosing between these two parts should recognize that the Radeon 860M has verified performance data, while the Arc G3 Extreme’s capabilities are entirely theoretical at this time. The Radeon 860M is the safer choice for a low-power integrated GPU with proven results. The Arc G3 Extreme is the choice only when the host device can supply 80 W and the workload demands the higher compute throughput that its specifications suggest.
