AMD Radeon 880M vs Intel Arc G3 Extreme Comparison

The Verdict

The data presents an unusual comparison. The AMD Radeon 880M is a fully measured part with a substantial set of benchmark results, while the Intel Arc G3 Extreme appears in the database with no recorded benchmarks, no average score, and no rival comparisons. The Intel part has a higher theoretical compute ceiling, but the absence of any measured performance data makes a direct performance verdict impossible.

For users who need a working integrated GPU with validated scores today, the AMD Radeon 880M is the only option with actual data. It sits at the 43rd percentile of all GPUs, with an average benchmark score of 8436. Its nearest rivals include the NVIDIA GeForce GTX 675MX (8427, 0.1% ahead), the AMD Radeon HD 8870M (8462, 0.3% ahead), and the AMD Radeon R9 M375X (8325, 1.3% behind). This places it in a narrow performance band where small percentage swings separate it from older discrete mobile parts.

The Intel Arc G3 Extreme, by contrast, is a 50th percentile GPU by database classification, but that percentile is not backed by any recorded test scores. The database shows it as a future-dated part with a 2026 release, using a 3 nm process and featuring double the shading units of the AMD part. Its theoretical FP32 throughput is 7.680 TFLOPS versus 4.454 TFLOPS for the AMD, and its pixel rate is 60.00 GPixel/s versus 46.40 GPixel/s. However, without benchmark results, those specifications cannot be translated into real-world performance.

The practical verdict: the AMD Radeon 880M is the part with proven measurements. The Intel Arc G3 Extreme is a specification sheet with promise but no validated data. Buyers who need confirmed performance should look at the AMD. Buyers considering the Intel part must wait for actual benchmark results to appear in the database.

Architecture Differences

The two integrated GPUs come from different manufacturers, use different process nodes, and are built on different architectures. The AMD Radeon 880M uses the Strix Point chip, built on RDNA 3.5 architecture, fabricated by TSMC on a 4 nm process. The chip contains 34,000 million transistors on a 233 mm² die, giving a transistor density of 145.9M per mm². The Intel Arc G3 Extreme uses the Panther Lake chip, built on Xe3-LPG architecture, fabricated by Intel on a 3 nm process. Intel's transistor count and die size are listed as unknown in the database, so no density comparison is possible.

The AMD part belongs to the Navi III IGP (Strix Point Mobile) generation, with a predecessor listed as Navi II IGP. The Intel part belongs to the Arc Graphics-M (Panther Lake) generation, with no predecessor listed. Both are active production parts, but the Intel release date is nearly two years after the AMD part.

The shading unit count differs substantially: the AMD has 768 shading units, while the Intel has 1536, exactly double. Both have 48 texture mapping units, but the AMD has 16 ROPs versus 24 on the Intel. Both have 12 ray tracing cores. Neither has tensor cores listed.

Clock behavior differs. The AMD runs at a 400 MHz base clock with a 2900 MHz boost, while the Intel runs at a 300 MHz base with a 2500 MHz boost. The AMD's higher boost clock partially compensates for its lower shader count, but the Intel's raw FP32 output is still higher.

Memory architecture is identical in form: both use System Shared memory, with system-dependent bandwidth. Both are IGP slot width, use no power connectors, and have portable-device-dependent display outputs. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The power envelope differs significantly: the AMD is rated at 15 W TDP, while the Intel is rated at 80 W TDP. This is a major architectural and practical difference, as the Intel part draws substantially more power for its higher theoretical throughput.

The bus interface also differs: the AMD uses PCIe 4.0 x8, while the Intel is listed simply as IGP.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two GPUs. The wins counter shows 0 for both parts. This is the central limitation of this comparison: there is no directly measured performance data where both parts ran the same test.

The AMD Radeon 880M does have its own benchmark scores, which can be interpreted against its nearest rivals. Its best single score is the Geekbench Vulkan result of 40006, followed by Geekbench OpenCL at 31285. In Passmark tests, the G3D score of 7615 dominates its other Passmark results, with G2D at 969 and GPU Compute at 3719. The DirectX-specific Passmark scores are low: DX11 at 73, DX9 at 97, DX10 at 31, DX12 at 32. The 3DMark Steel Nomad DX12 score is 535.

Against its nearest rivals, the AMD Radeon 880M is effectively tied with the NVIDIA GeForce GTX 675MX (8427 average, 0.1% behind), effectively tied with the AMD Radeon HD 8870M (8462 average, 0.3% behind), and 1.3% ahead of the AMD Radeon R9 M375X (8325 average). It is 0.3% behind the NVIDIA GeForce MX330 (8458 average). This indicates the AMD 880M performs in a very tight band around these older discrete mobile GPUs.

For the Intel Arc G3 Extreme, there are no benchmark scores to walk through. Its theoretical specifications suggest it should outperform the AMD in raw compute, given the FP32 and pixel rate advantages, but the database provides no measured confirmation. Any head-to-head analysis must stop at the specification level.

Where Each One Wins

Based strictly on recorded data, the AMD Radeon 880M wins in every measurable category because it is the only part with measurements. It has an average benchmark score of 8436, a 43rd percentile ranking, and ten individual test results. The Intel Arc G3 Extreme has no scores, no average, and no rivals.

The AMD part also wins on power efficiency. At 15 W TDP, it delivers its measured performance at a fraction of the Intel part's 80 W TDP. For portable devices where power draw is a constraint, the AMD is the clear choice based on the recorded data.

The Intel part wins on theoretical specification headroom. Its 1536 shading units, 7.680 TFLOPS FP32, 15.36 TFLOPS FP16, 60.00 GPixel/s pixel rate, and 24 ROPs all exceed the AMD's corresponding specifications. The Intel also uses a newer 3 nm process node. If those specifications translate into benchmark performance, the Intel could occupy a higher performance tier. But the database does not confirm this.

For users who need a working integrated GPU with validated performance today, the AMD Radeon 880M is the only option with data. For users who can wait for the Intel part's benchmark results to appear, the specifications suggest potential, but that potential is unverified. The AMD sits in a narrow competitive band around older discrete parts like the GTX 675MX and HD 8870M. The Intel remains an unknown quantity until its measurements are recorded.
