AMD Radeon 780M vs Intel Arc G3 Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Radeon 780M and the Intel Arc G3 presents an unusual comparison because the Intel Arc G3 has no benchmark entries in the database. Its average benchmark score is listed as 0, and its benchmark array is empty. This means a direct score-by-score comparison is not possible for any individual test. The AMD Radeon 780M, in contrast, has three recorded benchmark scores: 480 in 3DMark Steel Nomad DX12, 18602 in Geekbench OpenCL, and 33683 in Geekbench Vulkan. These scores produce an average benchmark score of 17588 for the 780M.

Because the Intel Arc G3 lacks any recorded scores, the database shows zero wins for each product in head-to-head testing. The head-to-head benchmark array is empty. The data indicates that the Radeon 780M sits at the 61st percentile among all GPUs, while the Arc G3 sits at the 50th percentile. This percentile gap alone suggests the 780M occupies a higher position in the overall performance distribution, but without actual Arc G3 scores, the delta cannot be quantified.

The Radeon 780M's nearest rivals in the database are instructive for context. Its average score of 17588 is 0.2% above the AMD Radeon Pro 560 (17551) and 0.5% above the AMD Radeon Pro 460 (17509). It sits 0.3% below the NVIDIA GeForce RTX 4060 (17639) and 0.4% below the AMD Radeon HD 7790 (17666). These deltas are all within one percentage point, meaning the 780M clusters tightly with those discrete and older integrated parts. The Intel Arc G3 has no nearest rivals listed, so no similar positioning can be established for it.

The practical consequence is that any assessment of relative performance must rely on architectural specifications and raw compute figures rather than measured benchmark outcomes. The 780M delivers 8.909 TFLOPS of FP32 compute, while the Arc G3 delivers 6.144 TFLOPS. In FP16, the 780M also provides 8.909 TFLOPS at a 1:1 ratio, whereas the Arc G3 provides 12.29 TFLOPS at a 2:1 ratio. The 780M leads in pixel rate at 92.80 GPixel/s versus 48.00 GPixel/s and in texture rate at 139.2 GTexel/s versus 96.00 GTexel/s. These figures indicate the 780M has a substantial lead in rasterization throughput, while the Arc G3 has a notable advantage in half-precision compute.

The Verdict

The data points to the AMD Radeon 780M as the stronger choice for anyone prioritizing measured performance and established benchmark results. It has a full set of recorded scores, a 61st percentile ranking, and an average score of 17588. The Intel Arc G3, by contrast, has no recorded benchmarks and a 50th percentile ranking, which is a lower position despite the lack of data. The 780M also leads in FP32 compute, pixel rate, and texture rate, all of which are fundamental to rasterized gaming and general graphics workloads. The Arc G3's higher FP16 throughput (12.29 TFLOPS at 2:1) is its only clear compute advantage, but that comes at half precision and may not translate to typical graphics tasks.

For a system builder choosing between these two integrated GPUs, the 780M is the safer pick based on the database. Its transistor count is listed at 25,390 million on a 178 mm² die, and it uses TSMC's 4 nm process. The Arc G3 uses Intel's 3 nm process but has unknown transistor and die size data. The 780M also has a higher boost clock at 2900 MHz versus 2400 MHz for the Arc G3, and a higher base clock at 800 MHz versus 300 MHz. The 780M has more TMUs (48 versus 40), more ROPs (32 versus 20), and more RT cores (12 versus 10), though the Arc G3 has more shading units (1280 versus 768). The 780M is rated at 15 W TDP, while the Arc G3 is rated at 25 W TDP.

Specification Differences

The two integrated GPUs differ across several core specification fields. The AMD Radeon 780M uses a Phoenix chip with RDNA 3.0 architecture, while the Intel Arc G3 uses a Panther Lake chip with Xe3-LPG architecture. The 780M is built on a 4 nm process by TSMC, whereas the Arc G3 uses a 3 nm process by Intel. The 780M has a base clock of 800 MHz and a boost clock of 2900 MHz, compared to the Arc G3's base clock of 300 MHz and boost clock of 2400 MHz.

Shading units differ significantly: the 780M has 768, while the Arc G3 has 1280. The texture mapping units are 48 for the 780M and 40 for the Arc G3, and the ROPs are 32 for the 780M and 20 for the Arc G3. Ray tracing cores are 12 for the 780M and 10 for the Arc G3. The pixel rate is 92.80 GPixel/s for the 780M versus 48.00 GPixel/s for the Arc G3, and the texture rate is 139.2 GTexel/s versus 96.00 GTexel/s. FP32 compute is 8.909 TFLOPS for the 780M and 6.144 TFLOPS for the Arc G3. FP16 compute is 8.909 TFLOPS (1:1) for the 780M and 12.29 TFLOPS (2:1) for the Arc G3.

The TDP is 15 W for the 780M and 25 W for the Arc G3. The bus interface is PCIe 4.0 x8 for the 780M, while the Arc G3 lists "IGP" as its bus interface. Display outputs are "Motherboard Dependent" for the 780M and "Portable Device Dependent" for the Arc G3. The 780M has a release date of 2024-01-30, while the Arc G3 has a release date of 2026-05-31.

Architecture Differences

The architectural split is clear: the AMD Radeon 780M uses RDNA 3.0, and the Intel Arc G3 uses Xe3-LPG. The 780M belongs to the Navi III IGP (Phoenix) generation, while the Arc G3 belongs to the Arc Graphics-M (Panther Lake) generation. The 780M is manufactured on TSMC's 4 nm node and contains 25,390 million transistors on a 178 mm² die, yielding a transistor density of 142.6M per mm². The Arc G3 uses Intel's 3 nm node, but its transistor count and die size are listed as unknown.

The 780M's RDNA 3.0 architecture provides FP16 at a 1:1 ratio with FP32, meaning half-precision throughput matches full-precision throughput. The Arc G3's Xe3-LPG architecture provides FP16 at a 2:1 ratio, meaning half-precision throughput is double the FP32 figure. This is the defining architectural difference in compute capability. The 780M has 12 RT cores versus 10 for the Arc G3, and the 780M has 48 TMUs versus 40, plus 32 ROPs versus 20.

Both products support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both use system-shared memory with system-dependent bandwidth. Neither product has a launch MSRP listed in the database. The 780M's predecessor is listed as "Navi II IGP" and its successor as "Navi III IGP," while the Arc G3 has no predecessor or successor listed. The 780M's production status is Active, and the Arc G3's production status is also Active.

Where Each One Wins

The AMD Radeon 780M wins in every category where measured data exists. It has all three benchmark scores recorded, while the Arc G3 has none. The 780M wins on FP32 compute (8.909 TFLOPS versus 6.144 TFLOPS), pixel rate (92.80 GPixel/s versus 48.00 GPixel/s), texture rate (139.2 GTexel/s versus 96.00 GTexel/s), TMUs (48 versus 40), ROPs (32 versus 20), and RT cores (12 versus 10). It also has higher base and boost clocks, a lower TDP (15 W versus 25 W), and a higher percentile ranking (61 versus 50).

The Intel Arc G3 wins on shading units (1280 versus 768), FP16 compute (12.29 TFLOPS at 2:1 versus 8.909 TFLOPS at 1:1), and manufacturing process (3 nm versus 4 nm). These wins are real but narrower in practical impact. Higher shading unit count does not automatically translate to higher throughput when the 780M's higher clocks and TMU/ROP counts compensate. The FP16 advantage matters for compute workloads that use half precision, but the 780M's 1:1 ratio means its FP16 performance is identical to its FP32, which is simpler for developers to exploit.

For gaming and typical graphics workloads, the 780M is the clear winner based on rasterization throughput and measured scores. For compute-heavy tasks that can leverage FP16, the Arc G3 has a theoretical edge, but without benchmark data, that edge remains unverified. The 780M's lower TDP also makes it more suitable for compact or power-constrained systems. The Arc G3's 25 W TDP and portable-device-dependent display outputs suggest it targets a different form factor, possibly handhelds or ultra-portables, where the higher FP16 throughput might be useful for AI or compute tasks. The data supports the 780M for general graphics and the Arc G3 for specialized half-precision compute, with the caveat that the Arc G3's performance is entirely unmeasured.
