Analysis: Intel Arc B570 vs Intel Arc G3 Extreme
Head-to-Head Benchmarks
The Intel Arc B570 and Intel Arc G3 Extreme occupy very different positions in the database. The B570 is a discrete desktop GPU with a substantial benchmark history, while the G3 Extreme is an integrated graphics solution with no recorded benchmark scores. This makes direct numerical comparison impossible for most tests.
The B570 posts an average benchmark score of 20556 across its recorded tests. Its nearest rival in the database is the NVIDIA GeForce RTX 3070 Mobile with an average score of 20534, a delta of 0.1 percent in favor of the B570. The Intel Arc A750 sits 0.1 percent behind the B570 with an average score of 20582, while the AMD Radeon R9 M390X trails by 0.5 percent at 20662.
The G3 Extreme has an average benchmark score of 0 and no recorded test results. Its percentile ranking of 50 places it at the midpoint of all GPUs in the database, but this ranking reflects its classification rather than measured performance. The B570 ranks in the 65th percentile, placing it above the median GPU in the database.
In individual tests, the B570 demonstrates its strongest showing in Geekbench Vulkan with a score of 96844. Its OpenCL score reaches 83514. The Passmark G3D test returns 14195, while GPU Compute scores 7281. Legacy DirectX tests show smaller numbers: DirectX 9 scores 164, DirectX 11 scores 118, DirectX 10 scores 65, and DirectX 12 scores 72. The 2D test scores 661.
The B570 also records a 3DMark Steel Nomad DX12 score of 2649. No comparable figures exist for the G3 Extreme, as the database contains no benchmark entries for that part.
Where Each One Wins
The B570 wins every measurable category because it is the only one with recorded data. It delivers 11.52 TFLOPS of FP32 compute, which is 50 percent higher than the G3 Extreme's 7.680 TFLOPS. Texture rate favors the B570 at 360.0 GTexel/s versus 120.0 GTexel/s for the G3 Extreme, a threefold advantage. Pixel rate tells a similar story: the B570 achieves 200.0 GPixel/s against 60.00 GPixel/s for the G3 Extreme.
Memory separates the two decisively. The B570 has 10 GB of dedicated GDDR6 memory on a 160-bit bus, delivering 380.0 GB/s of bandwidth. The G3 Extreme uses system shared memory with system dependent bandwidth, meaning its performance scales with the host platform's memory configuration rather than a fixed specification.
The B570's shading unit count of 2304 exceeds the G3 Extreme's 1536 by 768 units. Texture mapping units number 144 versus 48, and ROPs number 80 versus 24. Ray tracing cores follow the same pattern: 18 on the B570, 12 on the G3 Extreme.
For gaming and GPU compute workloads, the B570's dedicated memory and higher throughput give it a clear advantage. The G3 Extreme's integrated design targets portable devices where power consumption matters more than raw performance.
Architecture Differences
The B570 uses the BMG-G21 chip built on the Xe2-HPG architecture, part of the Battlemage generation (Arc 5). It is fabricated on a 5 nm process at TSMC, packing 19,600 million transistors into a 272 mm² die. Transistor density reaches 72.1 million per square millimeter.
The G3 Extreme uses the Panther Lake chip built on the Xe3-LPG architecture, part of the Arc Graphics-M (Panther Lake) generation. It is fabricated on a 3 nm process at Intel. Transistor count and die size are listed as unknown in the database.
Both architectures support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B570 operates as a discrete card with a dual-slot form factor, a 1x 8-pin power connector, and a 450 W suggested PSU. The G3 Extreme is an integrated graphics processor (IGP) with no power connectors and no suggested PSU rating.
Clock behavior differs significantly. The B570 runs at a constant 2500 MHz for both base and boost clocks. The G3 Extreme has a 300 MHz base clock that boosts to 2500 MHz, indicating a power-saving design that ramps up under load. Memory clocks also diverge: the B570 uses 2375 MHz (19 Gbps effective) GDDR6, while the G3 Extreme relies on system shared memory.
The B570 was released on January 15, 2025, with a launch MSRP of 219 USD. The G3 Extreme has a release date of May 31, 2026. The B570 lists Alchemist as its predecessor; the G3 Extreme has no predecessor listed.
Specification Differences
The B570 provides 10 GB of GDDR6 memory with a 160-bit bus and 380.0 GB/s bandwidth. The G3 Extreme uses system shared memory with system dependent bandwidth.

The Verdict
The Intel Arc B570 is the clear choice for desktop users who need dedicated graphics performance. Its 11.52 TFLOPS FP32 compute, 380.0 GB/s memory bandwidth, and 18 ray tracing cores provide a complete feature set for gaming and compute workloads. The 65th percentile ranking among all GPUs in the database reflects its position as a solid mid-range discrete option. Its nearest rival, the NVIDIA GeForce RTX 3070 Mobile, trails by 0.1 percent, putting the B570 in competitive territory.
The Intel Arc G3 Extreme serves a different purpose entirely. As an integrated graphics processor with an 80 W TDP and no power connectors, it targets portable devices where efficiency matters more than raw throughput. Its 3 nm Intel process node and 300 MHz base clock indicate a design focused on power conservation rather than peak performance. The lack of benchmark data means its real-world capabilities cannot be quantified from the database.
The B570 wins on every measurable specification: shading units, TMUs, ROPs, ray tracing cores, pixel rate, texture rate, and FP32 compute. Its dedicated memory eliminates the system dependency that limits the G3 Extreme's bandwidth. For any workload that benefits from sustained GPU throughput, the B570 is the superior part.
The G3 Extreme wins on power efficiency and form factor. Its 80 W TDP is nearly half the B570's 150 W, and its IGP design requires no additional cooling or power delivery hardware. For thin-and-light portable systems, this integration is a practical advantage.
Choose the B570 for desktop builds where performance and dedicated memory are priorities. Choose the G3 Extreme for portable devices where integration and low power draw take precedence. The data does not support using the G3 Extreme as a performance-oriented GPU, but its architectural role as an integrated solution with DirectX 12 Ultimate support makes it a capable option for its intended market segment.
