AMD Radeon 780M vs Intel Arc Graphics 4 Xe Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark entries between the AMD Radeon 780M and the Intel Arc Graphics 4 Xe Mobile. The head-to-head benchmark field is empty, and neither part registers a win in direct comparison testing. This absence of matched testing means all comparative analysis must rely on the individual benchmark scores each adapter has generated under the database's standard test suite.

The AMD Radeon 780M has three recorded benchmark results. In 3DMark Steel Nomad DX12, it scores 480 points. In Geekbench OpenCL, it records 18602 points. In Geekbench Vulkan, it reaches 33683 points. These results combine into an average benchmark score of 17588 points. The Intel Arc Graphics 4 Xe Mobile has no recorded benchmark scores, no average score, and no percentile ranking beyond its 50th percentile placement among all GPUs. The database shows zero recorded performance entries for the Intel part.

The absence of Intel benchmark data creates a significant gap in quantitative comparison. The AMD part's 17588 average score places it at the 61st percentile of all GPUs in the database. The Intel part sits at the 50th percentile, but with no score to anchor that position, the percentile alone carries limited analytical weight. The nearest rival data for the AMD Radeon 780M helps contextualize its performance. The AMD Radeon Pro 560 averages 17551 points, a 0.2 percent difference. The NVIDIA GeForce RTX 4060 averages 17639 points, which is 0.3 percent below the 780M's score. The AMD Radeon HD 7790 averages 17666 points, 0.4 percent lower. The AMD Radeon Pro 460 averages 17509 points, 0.5 percent above the 780M. These four rivals sit within half a percentage point of the 780M's average, indicating a tightly clustered performance neighborhood around 17500 to 17700 points.

The Intel Arc Graphics 4 Xe Mobile has no nearest rivals listed in the database. Without benchmark scores or rival comparisons, its performance envelope cannot be quantified from the recorded data. The 50th percentile placement suggests a mid-pack position, but the database confirms no measured performance to validate that placement.

Architecture Differences

The two integrated GPUs diverge sharply in their underlying design. The AMD Radeon 780M uses the Phoenix chip built on RDNA 3.0 architecture, manufactured on a 4 nm process at TSMC. The Intel Arc Graphics 4 Xe Mobile uses the Panther Lake chip built on Xe3-LPG architecture, manufactured on a 3 nm process at Intel's own foundry. The AMD part belongs to the Navi III IGP generation, while the Intel part belongs to the Arc Graphics-M generation.

The AMD chip carries 25,390 million transistors on a 178 mm² die, yielding a transistor density of 142.6 million transistors per square millimeter. The Intel chip's transistor count and die size are listed as unknown in the database, so no density figure can be computed.

Clock behavior differs substantially. The AMD Radeon 780M runs a base clock of 800 MHz and boosts to 2900 MHz. The Intel Arc Graphics 4 Xe Mobile starts at a 300 MHz base and boosts to 2300 MHz. The AMD part's boost clock is 600 MHz higher than the Intel part's boost clock. Both use system-shared memory with system-dependent bandwidth.

Execution resources show a clear imbalance. The AMD Radeon 780M contains 768 shading units, 48 texture mapping units, 32 raster operation pipelines, and 12 ray tracing cores. The Intel Arc Graphics 4 Xe Mobile contains 512 shading units, 32 TMUs, 16 ROPs, and 4 ray tracing cores. The AMD part delivers 2.25 times the TMU count of the Intel part, exactly double the ROP count, and three times the ray tracing core count. Neither part lists tensor cores.

Rasterization and texture throughput follow the resource counts. The AMD Radeon 780M reaches 92.80 GPixel/s pixel rate and 139.2 GTexel/s texture rate. The Intel Arc Graphics 4 Xe Mobile reaches 36.80 GPixel/s and 73.60 GTexel/s. The AMD part's pixel throughput is 2.5 times higher, and its texture throughput is 1.9 times higher.

Compute performance diverges even more. The AMD Radeon 780M delivers 8.909 TFLOPS FP32 and 8.909 TFLOPS FP16 with a 1:1 ratio. The Intel Arc Graphics 4 Xe Mobile delivers 2.355 TFLOPS FP32 and 4.710 TFLOPS FP16 with a 2:1 ratio. The AMD part's FP32 throughput is 3.8 times higher than the Intel part's. The Intel part's FP16 output is double its own FP32 output, while the AMD part maintains a 1:1 ratio.

Power envelopes differ as well. The AMD Radeon 780M carries a 15 W TDP, while the Intel Arc Graphics 4 Xe Mobile carries a 25 W TDP. Both are integrated graphics processors with no power connectors and no slot width. The AMD part uses a PCIe 4.0 x8 bus interface, while the Intel part's bus interface is listed simply as IGP. Display outputs are motherboard dependent for the AMD part and portable device dependent for the Intel part.

API support matches across both parts. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Release dates differ by roughly two years: the AMD part launched January 30, 2024, and the Intel part launched January 26, 2026. Both remain in active production. The AMD part lists a predecessor in Navi II IGP and a successor in Navi III IGP.

Where Each One Wins

The AMD Radeon 780M wins on every measured performance metric in the database. Its FP32 compute of 8.909 TFLOPS exceeds the Intel part's 2.355 TFLOPS. Its pixel rate of 92.80 GPixel/s exceeds 36.80 GPixel/s. Its texture rate of 139.2 GTexel/s exceeds 73.60 GTexel/s. Its shading unit count of 768 exceeds 512. Its ROP count of 32 doubles the Intel part's 16. Its ray tracing core count of 12 triples the Intel part's 4. Its boost clock of 2900 MHz exceeds 2300 MHz. Its average benchmark score of 17588 stands against zero recorded scores for the Intel part.

The AMD part also carries architectural advantages in transistor count, with 25,390 million transistors documented versus an unknown count for the Intel part. The AMD part's die size is documented at 178 mm², while the Intel part's die size is unknown. The AMD part's 61st percentile placement among all GPUs exceeds the Intel part's 50th percentile.

The Intel Arc Graphics 4 Xe Mobile wins on process technology. Its 3 nm Intel process node is smaller than the 4 nm TSMC node used by the AMD part. The Intel part also carries a higher TDP at 25 W versus 15 W, which could indicate additional power headroom, though no performance data confirms what that headroom delivers. The Intel part's FP16 output of 4.710 TFLOPS exceeds its own FP32 output, a 2:1 ratio that the AMD part does not match. However, the AMD part's FP16 output of 8.909 TFLOPS still exceeds the Intel part's FP16 figure. The Intel part's later release date of January 26, 2026 places it two years newer than the AMD part.

The database records no wins for either part in direct head-to-head testing because no head-to-head benchmark entries exist. The comparative wins described here derive from the individual specification and benchmark fields.

The Verdict

The recorded data indicates the AMD Radeon 780M is the stronger performer on measured specifications. Its FP32 compute is 3.8 times higher, its pixel rate is 2.5 times higher, its texture rate is 1.9 times higher, and its shading unit count is 50 percent higher. The AMD part holds a 61st percentile ranking with an average benchmark score of 17588, while the Intel part holds a 50th percentile with no recorded score. The AMD part's nearest rivals cluster within half a percentage point of its average score, which suggests the 780M competes in a well-established performance tier.

The Intel Arc Graphics 4 Xe Mobile presents a newer design on a smaller 3 nm process node, but the database contains no benchmark results to support its performance claims. Its 25 W TDP exceeds the AMD part's 15 W TDP, and its FP16 ratio of 2:1 differs from the AMD part's 1:1 ratio, but without measured scores these differences cannot be interpreted as advantages. The Intel part's 50th percentile placement, while lower than the AMD part's 61st percentile, lacks the score data needed to understand its position.

For anyone selecting between these two integrated GPUs based on the database records, the AMD Radeon 780M offers documented performance across multiple benchmark tests, a clear percentile ranking, and superior specifications in every execution resource category. The Intel Arc Graphics 4 Xe Mobile offers a newer process node and a higher TDP, but its performance profile remains unquantified. The data supports the AMD part as the better-characterized and higher-performing option. The Intel part requires benchmark validation before its capabilities can be assessed against the AMD part's recorded results.
