Architecture Differences
The two GPUs come from different manufacturers and use different process nodes. The Intel Arc G3 uses a 3 nm node fabricated by Intel, while the NVIDIA GeForce RTX 5080 Mobile uses a 5 nm node fabricated by TSMC. The Arc G3 is built on the Xe3-LPG architecture with the Panther Lake chip, part of the Arc Graphics-M (Panther Lake) generation. The RTX 5080 Mobile uses the Blackwell 2.0 architecture with the GB203 chip, part of the GeForce 50 Mobile generation.
The RTX 5080 Mobile has 45,600 million transistors on a 378 mm² die, giving a transistor density of 120.6 million per square millimeter. The Arc G3's transistor count and die size are listed as unknown in the database.
Memory architecture separates the two clearly. The Arc G3 uses system shared memory, with system shared type, bus width, and system dependent bandwidth. The RTX 5080 Mobile has 16 GB of GDDR7 memory on a 256 bit bus with 896.0 GB/s bandwidth and a memory clock of 1750 MHz (28 Gbps effective).
Core counts differ dramatically. The Arc G3 has 1,280 shading units, 40 texture mapping units, 20 ROPs, and 10 ray tracing cores. The RTX 5080 Mobile has 7,680 shading units, 240 TMUs, 96 ROPs, 60 ray tracing cores, and 240 tensor cores. The Arc G3 lists no tensor cores in the database.
Clock behavior is distinct. The Arc G3 has a base clock of 300 MHz and a boost clock of 2400 MHz. The RTX 5080 Mobile has a base clock of 975 MHz and a boost clock of 1500 MHz. The Arc G3's boost clock is significantly higher, but the RTX 5080 Mobile's larger core count compensates.
The bus interface differs as well. The Arc G3 uses an integrated graphics processor (IGP) interface, while the RTX 5080 Mobile uses PCIe 5.0 x16. Both are listed with IGP slot width and no power connectors.
Where Each One Wins
The Arc G3's advantages come from its architecture and efficiency profile. Its 3 nm process node from Intel is smaller than the RTX 5080 Mobile's 5 nm TSMC node. The Arc G3 has a 25 W TDP, compared to the RTX 5080 Mobile's 80 W TDP. The Arc G3's boost clock of 2400 MHz exceeds the RTX 5080 Mobile's 1500 MHz boost clock. These factors point to a lower power draw and potentially better efficiency in thermally constrained systems.
The RTX 5080 Mobile wins on raw compute metrics. Its FP32 throughput is 23.04 TFLOPS against the Arc G3's 6.144 TFLOPS. FP16 performance is 23.04 TFLOPS for the RTX 5080 Mobile and 12.29 TFLOPS for the Arc G3. The pixel rate is 144.0 GPixel/s for the RTX 5080 Mobile versus 48.00 GPixel/s for the Arc G3. Texture rate is 360.0 GTexel/s versus 96.00 GTexel/s. Each of these figures shows the RTX 5080 Mobile at roughly 3.75 times the Arc G3's pixel rate and texture rate, and 3.75 times the FP32 throughput.
The RTX 5080 Mobile's 16 GB GDDR7 memory with 896.0 GB/s bandwidth is a major advantage over the Arc G3's system shared memory, which has system dependent bandwidth. The dedicated memory pool allows the RTX 5080 Mobile to sustain high bandwidth workloads without competing with the CPU for system memory.
The RTX 5080 Mobile also has more ray tracing cores, 60 versus 10 for the Arc G3, and it has 240 tensor cores while the Arc G3 has none listed. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Q: Are there any benchmark scores for the Arc G3?
A: The database lists no benchmark scores for the Arc G3. The RTX 5080 Mobile has an average benchmark score of 38,349 across tests including Geekbench Vulkan at 169,754, Geekbench OpenCL at 166,986, and PassMark G3D at 27,711.
The Verdict
The data supports a clear split. The NVIDIA GeForce RTX 5080 Mobile is the stronger performer by every measured compute metric. Its FP32 throughput of 23.04 TFLOPS, pixel rate of 144.0 GPixel/s, texture rate of 360.0 GTexel/s, and 60 ray tracing cores place it well above the Arc G3 in rendering capability. Its 16 GB GDDR7 memory with 896.0 GB/s bandwidth provides a dedicated memory pool that the Arc G3's system shared memory cannot match. The recorded benchmark results, including an average score of 38,349 and an 81st percentile ranking, confirm its position among all GPUs.
The Intel Arc G3 offers a different profile. Its 3 nm process node and 25 W TDP suggest a lower power envelope. Its 2400 MHz boost clock is higher than the RTX 5080 Mobile's 1500 MHz boost clock. For systems where power draw is the primary constraint, the Arc G3's specifications align with that requirement. The lack of benchmark data means its real-world performance cannot be verified from the database.
Users needing maximum graphics throughput, large dedicated memory, and ray tracing capability should look at the RTX 5080 Mobile. Users prioritizing low power consumption and a smaller process node may find the Arc G3 more suitable, though its performance remains unmeasured in the database. The RTX 5080 Mobile's nearest rivals, including the RTX 4080 Mobile and MX570 variants, all fall within about one percent of its average score, so the competition at this level is tight.
