Intel Arc G3 Extreme vs Intel Arc Pro B60 Dual Comparison

Intel Arc G3 Extreme and Intel Arc Pro B60 Dual represent two distinct approaches within Intel’s graphics lineup, one integrated into a mobile processor and the other a dedicated professional add-in board. The recorded data shows both cards occupy the 50th percentile in the database’s global ranking, yet their specifications and intended operating environments diverge sharply. The G3 Extreme uses the Panther Lake chip with Xe3-LPG architecture on Intel’s 3 nm process, while the Pro B60 Dual uses the BMG-G21 chip with Xe2-HPG architecture on TSMC’s 5 nm process. This comparison relies solely on the database records, including physical dimensions, memory configurations, and compute throughput figures.

The Verdict

The database indicates two different buyers. The Intel Arc G3 Extreme is an integrated processor solution, with an 80 W TDP, no power connectors, and system-shared memory. It suits compact portable devices where space and power are constrained; its 300 MHz base clock rising to 2500 MHz boost suggests a design tuned for burst workloads within a tight thermal envelope. The Arc Pro B60 Dual, by contrast, is a 400 W dual-slot card with a 16-pin connector and an 800 W suggested power supply. It targets professional workstations needing 24 GB of dedicated GDDR6 memory and four mini-DisplayPort 2.1 outputs.

Given the compute figures, the Pro B60 Dual holds a clear advantage in raw throughput: 12.29 TFLOPS FP32 versus 7.680 TFLOPS, and 24.58 TFLOPS FP16 versus 15.36 TFLOPS. Its pixel rate of 192.0 GPixel/s and texture rate of 384.0 GTexel/s dwarf the G3 Extreme’s 60.00 GPixel/s and 120.0 GTexel/s. The G3 Extreme, however, consumes one-fifth the power and requires no external power delivery. The data does not include benchmark scores or rival comparisons, so the verdict rests on specification deltas: the Pro B60 Dual for sustained, high-throughput rendering tasks, the G3 Extreme for integrated, low-power mobile deployments.

Head-to-Head Benchmarks

No head-to-head benchmark entries exist in the database for these two cards, and neither has recorded benchmark scores or nearest rivals. The comparison therefore falls entirely on measured specification data. In FP32 compute, the Pro B60 Dual’s 12.29 TFLOPS exceeds the G3 Extreme’s 7.680 TFLOPS by 4.61 TFLOPS. In FP16, the Pro B60 Dual’s 24.58 TFLOPS exceeds the G3 Extreme’s 15.36 TFLOPS by 9.22 TFLOPS. Texture rate shows a similar pattern: 384.0 GTexel/s versus 120.0 GTexel/s, a threefold difference. Pixel rate scales to 192.0 GPixel/s versus 60.00 GPixel/s, also a threefold gap.

Memory bandwidth is not comparable in absolute terms because the G3 Extreme shares system memory and its bandwidth is System Dependent. The Pro B60 Dual provides a fixed 456.0 GB/s over a 192 bit GDDR6 interface. Clock behavior also differs: the G3 Extreme has a lower base clock of 300 MHz but a higher boost of 2500 MHz, while the Pro B60 Dual idles at 2000 MHz and boosts to 2400 MHz. The Pro B60 Dual’s higher base clock suggests sustained operation closer to peak, whereas the G3 Extreme’s wide clock range implies aggressive power management.

The shading unit count favors the Pro B60 Dual: 2560 shading units, 160 TMUs, and 80 ROPs against 1536 shading units, 48 TMUs, and 24 ROPs. Ray tracing cores number 20 on the Pro B60 Dual versus 12 on the G3 Extreme. Every compute-related metric in the database favors the dedicated card, with the G3 Extreme’s advantages limited to lower power and integrated form factor.

Specification Differences

The two cards differ across nearly every recorded field. The Arc G3 Extreme uses the Panther Lake chip with Xe3-LPG architecture, built on a 3 nm process at Intel’s foundry. The Arc Pro B60 Dual uses the BMG-G21 chip with Xe2-HPG architecture, built on a 5 nm process at TSMC. Transistor count is unknown for the G3 Extreme, while the Pro B60 Dual lists 19,600 million transistors on a 272 mm² die with a density of 72.1M per mm².

Clock speeds: the G3 Extreme runs at 300 MHz base and 2500 MHz boost; the Pro B60 Dual runs at 2000 MHz base and 2400 MHz boost. Memory: the G3 Extreme has System Shared memory with System Dependent bandwidth; the Pro B60 Dual has 24 GB GDDR6, 192 bit bus, 456.0 GB/s, and a 2375 MHz memory clock with 19 Gbps effective speed. Compute units: 1536 shading units, 48 TMUs, 24 ROPs, 12 RT cores for the G3 Extreme; 2560 shading units, 160 TMUs, 80 ROPs, 20 RT cores for the Pro B60 Dual.

Rates: the G3 Extreme posts 60.00 GPixel/s and 120.0 GTexel/s; the Pro B60 Dual posts 192.0 GPixel/s and 384.0 GTexel/s. Power: 80 W TDP with no connectors for the G3 Extreme; 400 W TDP, 1x 16-pin connector, and 800 W suggested PSU for the Pro B60 Dual. Form factor: IGP for the G3 Extreme; dual-slot for the Pro B60 Dual, measuring 300 mm by 110 mm by 40 mm. Bus interface: IGP for the G3 Extreme; PCIe 5.0 x8 for the Pro B60 Dual. Display outputs: Portable Device Dependent for the G3 Extreme; 4x mini-DisplayPort 2.1 for the Pro B60 Dual.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Architecture Differences

The G3 Extreme uses Xe3-LPG, Intel’s low-power graphics architecture, implemented on a 3 nm Intel process. The LPG designation typically aligns with integrated graphics, and the data supports this: System Shared memory, IGP bus interface, no power connectors, and an 80 W TDP. The base clock of 300 MHz is exceptionally low, indicating a power-saving idle state, while the 2500 MHz boost shows the architecture can scale up when thermal headroom allows. The 12 RT cores and 1536 shading units reflect a design balanced for mobile efficiency rather than maximum throughput.

The Pro B60 Dual uses Xe2-HPG, Intel’s high-performance graphics architecture, on a 5 nm TSMC process. The HPG designation aligns with discrete, high-performance parts, and the data confirms this: 24 GB GDDR6, PCIe 5.0 x8, a dual-slot cooler, and a 400 W TDP. The transistor count of 19,600 million on a 272 mm² die gives a density of 72.1M per mm². The 2560 shading units, 160 TMUs, and 80 ROPs provide a substantially wider execution width. The 20 RT cores double the ray tracing hardware of the G3 Extreme’s 12.

Process node differences are notable: 3 nm for the G3 Extreme versus 5 nm for the Pro B60 Dual. The foundries also differ, with Intel fabricating the G3 Extreme and TSMC fabricating the Pro B60 Dual. Both architectures share API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, so software feature parity exists at the API level. The architectural split is clear: one low-power integrated design, one high-power discrete design, with the compute and memory systems scaled accordingly.

Where Each One Wins

The Intel Arc G3 Extreme wins in power efficiency and integration. Its 80 W TDP is one-fifth of the Pro B60 Dual’s 400 W, and it requires no external power connectors or suggested PSU. As an IGP with system-shared memory, it fits into portable devices where the Pro B60 Dual’s 300 mm length and dual-slot width would be impossible. The G3 Extreme’s boost clock of 2500 MHz exceeds the Pro B60 Dual’s 2400 MHz, indicating it can reach higher peak frequencies when power and thermals permit. It is also the newer entry in the database, with a release date of 2026-05-31 versus the Pro B60 Dual’s 2025-09-04.

The Intel Arc Pro B60 Dual wins in every raw performance metric recorded. FP32 compute of 12.29 TFLOPS exceeds the G3 Extreme’s 7.680 TFLOPS. FP16 compute of 24.58 TFLOPS exceeds 15.36 TFLOPS. Pixel rate of 192.0 GPixel/s is three times the G3 Extreme’s 60.00 GPixel/s, and texture rate of 384.0 GTexel/s is three times 120.0 GTexel/s. The 24 GB GDDR6 memory with 456.0 GB/s bandwidth provides dedicated, predictable memory performance, whereas the G3 Extreme relies on system memory with bandwidth marked System Dependent. The 4x mini-DisplayPort 2.1 outputs give the Pro B60 Dual a fixed multi-display capability, while the G3 Extreme’s outputs depend on the host portable device.

Use-case split follows the data. The G3 Extreme suits low-power integrated systems where space, cooling, and power draw are primary constraints. The Pro B60 Dual suits workstation or professional rendering environments where 24 GB of dedicated memory, high pixel throughput, and multi-display output are required. The database records no benchmark scores for either card, so these conclusions derive from specification differences alone. The 50th percentile ranking for both cards places them in the middle of the database’s global distribution, but that percentile does not reflect any recorded head-to-head result.
