AMD Radeon 860M vs Intel Arc Graphics 128EU Mobile Comparison

Head-to-Head Benchmarks

The database contains benchmark results for the AMD Radeon 860M, while the Intel Arc Graphics 128EU Mobile has no recorded benchmark scores. This makes a direct numerical comparison impossible for compute workloads. The AMD Radeon 860M achieves an average benchmark score of 26401, placing it in the 72nd percentile of all GPUs. Its recorded scores include 22759 in Geekbench OpenCL and 30043 in Geekbench Vulkan.

The nearest rivals for the AMD Radeon 860M provide context for its standing. The NVIDIA GeForce MX550 scores 26421, which is 0.1% higher than the Radeon 860M. The NVIDIA GeForce RTX 5060 scores 26331, placing it 0.3% behind. The AMD Radeon RX 5700 XT 50th Anniversary scores 26553, which is 0.6% ahead. The NVIDIA RTX A4000 scores 26683, leading by 1.1%. These deltas are all within a narrow band, indicating the Radeon 860M sits in a tightly contested performance cluster.

The Intel Arc Graphics 128EU Mobile has no benchmark entries and no nearest rivals listed. Its average benchmark score is recorded as 0, and its percentile is 50. This means the data set cannot establish any head-to-head wins for either part, since only one side has measurable performance. The wins counters are both zero.

Architecture Differences

The AMD Radeon 860M uses the RDNA 3.5 architecture on a 4 nm process from TSMC. It belongs to the Navi III IGP generation for Strix Point Mobile, with the chip named Krackan Point. The Intel Arc Graphics 128EU Mobile uses the Xe-LPG architecture on a 10 nm process from Intel. Its chip is Meteor Lake, and it belongs to the Arc Graphics-M generation for Meteor Lake.

The process node difference is substantial: 4 nm versus 10 nm. The AMD part is fabricated by TSMC, while Intel fabricates its own chip. Transistor counts and die sizes are unknown for both parts in the database.

The AMD Radeon 860M has 512 shading units, 32 texture mapping units, and 16 render output units. It includes 8 ray tracing cores. The Intel Arc Graphics 128EU Mobile has 1024 shading units, 64 texture mapping units, and 32 render output units. It has no ray tracing cores listed. The Intel part doubles the AMD part in shading units, TMUs, and ROPs.

Clock behavior differs significantly. The AMD Radeon 860M has a base clock of 600 MHz and a boost clock of 3000 MHz. The Intel Arc Graphics 128EU Mobile has a base clock of 300 MHz and a boost clock of 2250 MHz. The AMD part boosts 750 MHz higher and starts at double the base frequency.

The AMD Radeon 860M supports DirectX 12 Ultimate (12_2), while the Intel Arc Graphics 128EU Mobile supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The AMD part uses PCIe 4.0 x8 as its bus interface, while the Intel part uses a Ring Bus interface.

Both parts have system shared memory with system dependent bandwidth. Neither has dedicated memory. The AMD part is rated at 15 W TDP, while the Intel part is rated at 28 W TDP.

Where Each One Wins

The recorded data shows the AMD Radeon 860M holds an average benchmark score of 26401, while the Intel Arc Graphics 128EU Mobile has no recorded scores. This means the AMD part wins in every measurable benchmark category by default, since the Intel part has no data. The AMD part's Geekbench Vulkan score of 30043 is its stronger result, exceeding its OpenCL score of 22759 by a significant margin.

The AMD Radeon 860M's nearest rivals all score within 1.1% of its average, which suggests it competes in a performance tier populated by discrete mobile GPUs like the GeForce MX550 and the RTX 5060, as well as the older Radeon RX 5700 XT 50th Anniversary and the RTX A4000. The small deltas indicate the Radeon 860M is not dominant in its tier; it sits near the middle of a narrow band.

For the Intel Arc Graphics 128EU Mobile, the absence of benchmark data means no wins can be identified. The part has a higher theoretical FP32 throughput at 4.608 TFLOPS versus 3.072 TFLOPS for the AMD part, and a higher pixel rate at 72.00 GPixel/s versus 48.00 GPixel/s. It also has a higher texture rate at 144.0 GTexel/s versus 96.00 GTexel/s. These raw specifications suggest the Intel part could be competitive in certain workloads, but the database contains no scores to confirm actual performance.

The AMD part has a lower TDP at 15 W, which may indicate efficiency advantages in thermally constrained systems. The Intel part is rated at 28 W, nearly double the power envelope. Without benchmark data for the Intel part, the practical impact of this difference cannot be quantified.

The Verdict

The data clearly favors the AMD Radeon 860M in terms of measurable performance. It has a substantial average benchmark score of 26401, placing it in the 72nd percentile of all GPUs. The Intel Arc Graphics 128EU Mobile has no recorded benchmark scores, so its real-world performance cannot be assessed from the database.

The AMD Radeon 860M also holds advantages in clock speeds, with a 3000 MHz boost clock versus 2250 MHz for the Intel part. It has a more advanced process node at 4 nm versus 10 nm, and it includes 8 ray tracing cores while the Intel part has none. Its DirectX 12 Ultimate support exceeds the Intel part's DirectX 12 (12_1) support.

The Intel Arc Graphics 128EU Mobile has theoretical advantages in raw compute specifications. It doubles the shading units, TMUs, and ROPs. Its FP32 throughput is 4.608 TFLOPS versus 3.072 TFLOPS, and its FP16 throughput is 9.216 TFLOPS versus 3.072 TFLOPS. It also has higher pixel and texture rates. However, none of these specifications translate into recorded benchmark scores in the database.

The AMD Radeon 860M is the only part with any performance evidence. It sits within 1.1% of four discrete GPUs, which indicates it performs at a level comparable to those parts. The Intel Arc Graphics 128EU Mobile cannot be recommended based on the data, since no scores exist to validate its theoretical specifications.

For systems where measured performance matters, the AMD Radeon 860M is the choice. Its 15 W TDP also suggests lower power consumption than the Intel part's 28 W. The Intel part may have higher theoretical throughput, but the database provides no confirmation of that in practice.
